1.0 Overview

The BaseRowSet class provides the following:

• Properties
  • Fields for storing current properties
  • Methods for getting and setting properties

• Event notification

• A complete set of setter methods for setting the parameters in a RowSet object's command

• Streams
  • Fields for storing stream instances
  • Constants for indicating the type of a stream

2.0 Setting Properties

NOTE: In order to use a DataSource object for making a connection, the DataSource object must have been registered with a naming service that uses the Java Naming and Directory Interface^TM (JNDI) API. This registration is usually done by a person acting in the capacity of a system administrator.

3.0 Setting the Command and Its Parameters

The following code fragment illustrates how the CachedRowSet^TM object crs might have its command property set. Note that if a tool is used to set properties, this is the code that the tool would use.

 crs.setCommand("SELECT FIRST_NAME, LAST_NAME, ADDRESS FROM CUSTOMERS" +
 "WHERE CREDIT_LIMIT > ? AND REGION = ?");
 

In this example, the values for CREDIT_LIMIT and REGION are placeholder parameters, which are indicated with a question mark (?). The first question mark is placeholder parameter number 1, the second question mark is placeholder parameter number 2, and so on. Any placeholder parameters must be set with values before the query can be executed. To set these placeholder parameters, the BaseRowSet class provides a set of setter methods, similar to those provided by the PreparedStatement interface, for setting values of each data type. A RowSet object stores the parameter values internally, and its execute method uses them internally to set values for the placeholder parameters before it sends the command to the DBMS to be executed.

The following code fragment demonstrates setting the two parameters in the query from the previous example.

 crs.setInt(1, 5000);
 crs.setString(2, "West");
 

 "SELECT FIRST_NAME, LAST_NAME, ADDRESS FROM CUSTOMERS" +
 "WHERE CREDIT_LIMIT > 5000 AND REGION = 'West'"
 

4.0 Handling of Parameters Behind the Scenes

The placeholder parameters set with the BaseRowSet setter methods are stored as objects in an internal Hashtable object. Primitives are stored as their Object type. For example, byte is stored as Byte object, and int is stored as an Integer object. When the method execute is called, the values in the Hashtable object are substituted for the appropriate placeholder parameters in the command. A call to the method getParams returns the values stored in the Hashtable object as an array of Object instances. An element in this array may be a simple Object instance or an array (which is a type of Object). The particular setter method used determines whether an element in this array is an Object or an array.

The majority of methods for setting placeholder parameters take two parameters, with the first parameter indicating which placeholder parameter is to be set, and the second parameter giving the value to be set. Methods such as getInt, getString, getBoolean, and getLong fall into this category. After these methods have been called, a call to the method getParams will return an array with the values that have been set. Each element in the array is an Object instance representing the values that have been set. The order of these values in the array is determined by the int (the first parameter) passed to the setter method. The values in the array are the values (the second parameter) passed to the setter method. In other words, the first element in the array is the value to be set for the first placeholder parameter in the RowSet object's command. The second element is the value to be set for the second placeholder parameter, and so on.

Several setter methods send the driver and DBMS information beyond the value to be set. When the method getParams is called after one of these setter methods has been used, the elements in the array will themselves be arrays to accommodate the additional information. In this category, the method setNull is a special case because one version takes only two parameters (setNull(int parameterIndex, int SqlType)). Nevertheless, it requires an array to contain the information that will be passed to the driver and DBMS. The first element in this array is the value to be set, which is null, and the second element is the int supplied for sqlType, which indicates the type of SQL value that is being set to null. This information is needed by some DBMSs and is therefore required in order to ensure that applications are portable. The other version is intended to be used when the value to be set to null is a user-defined type. It takes three parameters (setNull(int parameterIndex, int sqlType, String typeName)) and also requires an array to contain the information to be passed to the driver and DBMS. The first two elements in this array are the same as for the first version of setNull. The third element, typeName, gives the SQL name of the user-defined type. As is true with the other setter methods, the number of the placeholder parameter to be set is indicated by an element's position in the array returned by getParams. So, for example, if the parameter supplied to setNull is 2, the second element in the array returned by getParams will be an array of two or three elements.

Some methods, such as setObject and setDate have versions that take more than two parameters, with the extra parameters giving information to the driver or the DBMS. For example, the methods setDate, setTime, and setTimestamp can take a Calendar object as their third parameter. If the DBMS does not store time zone information, the drivern uses the Calendar object to construct the Date, Time, or Timestamp object being set. As is true with other methods that provide additional information, the element in the array returned by getParams is an array instead of a simple Object instance.

The methods setAsciiStream, setBinaryStream, setCharacterStream, and setUnicodeStream (which is deprecated, so applications should use getCharacterStream instead) take three parameters, so for them, the element in the array returned by getParams is also an array. What is different about these setter methods is that in addition to the information provided by parameters, the array contains one of the BaseRowSet constants indicating the type of stream being set.

NOTE: The method getParams is called internally by RowSet implementations extending this class; it is not normally called by an application programmer directly.

5.0 Event Notification

A listener is an object that has implemented the RowSetListener interface. If it has been added to a RowSet object's list of listeners, it will be notified when an event occurs on that RowSet object. Each listener's implementation of the RowSetListener methods defines what that object will do when it is notified that an event has occurred.

There are three possible events for a RowSet object:

1. the cursor moves
2. an individual row is changed (updated, deleted, or inserted)
3. the contents of the entire RowSet object are changed

The BaseRowSet method used for the notification indicates the type of event that has occurred. For example, the method notifyRowChanged indicates that a row has been updated, deleted, or inserted. Each of the notification methods creates a RowSetEvent object, which is supplied to the listener in order to identify the RowSet object on which the event occurred. What the listener does with this information, which may be nothing, depends on how it was implemented.

6.0 Default Behavior

• Has a scrollable cursor and does not show changes made by others.
• Is updatable.
• Does not show rows that have been deleted.
• Has no time limit for how long a driver may take to execute the RowSet object's command.
• Has no limit for the number of rows it may contain.
• Has no limit for the number of bytes a column may contain. NOTE: This limit applies only to columns that hold values of the following types: BINARY, VARBINARY, LONGVARBINARY, CHAR, VARCHAR, and LONGVARCHAR.
• Will not see uncommitted data (make "dirty" reads).
• Has escape processing turned on.
• Has its connection's type map set to null.
• Has an empty Vector object for storing the values set for the placeholder parameters in the RowSet object's command.

If other values are desired, an application must set the property values explicitly. For example, the following line of code sets the maximum number of rows for the CachedRowSet object crs to 500.

 crs.setMaxRows(500);
 

A listener might, for example, be a table or graph that needs to be updated in order to accurately reflect the current state of the RowSet object.

Note: if the RowSetListener object is null, this method silently discards the null value and does not add a null reference to the set of listeners.

In general, parameter values remain in force for repeated use in this RowSet object's command.

Drivers that support the JDBC 3.0 API will create Connection objects with an associated type map.

When an application calls a method that changes a row, such as the CachedRowSet methods insertRow, updateRow, or deleteRow, that method calls notifyRowChanged internally.

When an application calls methods that change the entire contents of the RowSet object, such as the CachedRowSet methods execute, populate, restoreOriginal, or release, that method calls notifyRowSetChanged internally (either directly or indirectly).

The command property may not be needed if the RowSet object gets its data from a source that does not support commands, such as a spreadsheet or other tabular file. Thus, this property is optional and may be null.

The parameter value set by this method is stored internally and will be supplied as the appropriate parameter in this RowSet object's command when the method execute is called.

The JDBC specification specifies a standard mapping from Java Object types to SQL types.

The parameter value set by this method is stored internally and will be supplied as the appropriate parameter in this RowSet object's command when the method execute is called.

A listener might, for example, be a table or graph that needs to be updated in order to accurately reflect the current state of the RowSet object.

Note: if the RowSetListener object is null, this method silently discards the null value and does not add a null reference to the set of listeners.

Note: if the listener is already set, and the new RowSetListerner instance is added to the set of listeners already registered to receive event notifications from this RowSet.
Parameters:
  listener - an object that has implemented thejavax.sql.RowSetListener interface and wants to be notifiedof any events that occur on this RowSet object; May benull.
See Also:   BaseRowSet.removeRowSetListener

In general, parameter values remain in force for repeated use in this RowSet object's command. Setting a parameter value with the setter methods automatically clears the value of the designated parameter and replaces it with the new specified value.

This method is called internally by the setCommand method to clear all of the parameters set for the previous command.

Furthermore, this method differs from the initParams method in that it maintains the schema of the RowSet object.
throws:
  SQLException - if an error occurs clearing the parameters

The SQL query returned by this method is used by RowSet methods such as execute and populate, which may be implemented by any class that extends the BaseRowSet abstract class and implements one or more of the standard JSR-114 RowSet interfaces.

The command is used by the RowSet object's reader to obtain a ResultSet object. The reader then reads the data from the ResultSet object and uses it to to populate this RowSet object.

The default value for the command property is null. the String that is the value for thisRowSet object's command property;may be null
See Also:   BaseRowSet.setCommand

An application can call the method setConcurrency at any time to change a RowSet object's concurrency.

the concurrency type for this RowSetobject, which must be one of the following:ResultSet.CONCUR_READ_ONLY orResultSet.CONCUR_UPDATABLE
throws:
  SQLException - if an error occurs getting the concurrencyof this RowSet object
See Also:   BaseRowSet.setConcurrency
See Also:   BaseRowSet.isReadOnly

Users should set either the url or the data source name property. The driver will use the property set most recently to establish a connection. a String object that identifies theDataSource object to be used for making a connection; if no logical name has been set, null is returned.
See Also:   BaseRowSet.setDataSourceName

Each element in the array that is returned is an Object instance that contains the values of the parameters supplied to a setter method. The order of the elements is determined by the value supplied for parameterIndex. If the setter method takes only the parameter index and the value to be set (possibly null), the array element will contain the value to be set (which will be expressed as an Object). If there are additional parameters, the array element will itself be an array containing the value to be set plus any additional parameter values supplied to the setter method. If the method sets a stream, the array element includes the type of stream being supplied to the method. These additional parameters are for the use of the driver or the DBMS and may or may not be used.

NOTE: Stored parameter values of types Array, Blob, Clob and Ref are returned as SerialArray, SerialBlob, SerialClob and SerialRef respectively. an array of Object instances that includes the parameter values that may be set in this RowSet object'scommand; an empty array if no parameters have been set
throws:
  SQLException - if an error occurs retrieveing the object array ofparameters of this RowSet object or if not all parameters havebeen set

Note: Allowing deleted rows to remain visible complicates the behavior of some of the methods. However, most RowSet object users can simply ignore this extra detail because only sophisticated applications will likely want to take advantage of this feature. true if deleted rows are visible;false otherwise
throws:
  SQLException - if an error occurs determining if deleted rowsare visible or not
See Also:   BaseRowSet.setShowDeleted

For RowSet implementations such as the CachedRowSet that operate in a disconnected environment, the SyncProvider object offers complementary locking and data integrity options. The options described below are pertinent only to connected RowSet objects (JdbcRowSet objects). one of the following constants:Connection.TRANSACTION_NONE,Connection.TRANSACTION_READ_UNCOMMITTED,Connection.TRANSACTION_READ_COMMITTED,Connection.TRANSACTION_REPEATABLE_READ, orConnection.TRANSACTION_SERIALIZABLE
See Also:   javax.sql.rowset.spi.SyncFactory
See Also:   javax.sql.rowset.spi.SyncProvider
See Also:   BaseRowSet.setTransactionIsolation

Drivers that support the JDBC 3.0 API will create Connection objects with an associated type map. This type map, which is initially empty, can contain one or more fully-qualified SQL names and Class objects indicating the class to which the named SQL value will be mapped. The type mapping specified in the connection's type map is used for custom type mapping when no other type map supersedes it.

If a type map is explicitly supplied to a method that can perform custom mapping, that type map supersedes the connection's type map. the java.util.Map object that is the type mapfor this RowSet object's connection

The Url property will be null if the underlying data source is a non-SQL data source, such as a spreadsheet or an XML data source. a String object that contains the JDBC URLused to establish the connection for this RowSetobject; may be null (default value) if not set
throws:
  SQLException - if an error occurs retrieving the URL value
See Also:   BaseRowSet.setUrl

When an application calls a method to move the cursor, that method moves the cursor and then calls this method internally. An application should never invoke this method directly.
throws:
  SQLException - if the class extending the BaseRowSetabstract class does not implement the RowSet interface orone of it's sub-interfaces.

When an application calls a method that changes a row, such as the CachedRowSet methods insertRow, updateRow, or deleteRow, that method calls notifyRowChanged internally. An application should never invoke this method directly.
throws:
  SQLException - if the class extending the BaseRowSetabstract class does not implement the RowSet interface orone of it's sub-interfaces.

When an application calls methods that change the entire contents of the RowSet object, such as the CachedRowSet methods execute, populate, restoreOriginal, or release, that method calls notifyRowSetChanged internally (either directly or indirectly). An application should never invoke this method directly.
throws:
  SQLException - if the class extending the BaseRowSetabstract class does not implement the RowSet interface orone of it's sub-interfaces.

The parameter value set by this method is stored internally and will be supplied as the appropriate parameter in this RowSet object's command when the method execute is called. Methods such as execute and populate must be provided in any class that extends this class and implements one or more of the standard JSR-114 RowSet interfaces.

Note: JdbcRowSet does not require the populate method as it is undefined in this class.

After this method has been called, a call to the method getParams will return an object array of the current command parameters, which will include the Array object set for placeholder parameter number parameterIndex. Note that because the numbering of elements in an array starts at zero, the array element that corresponds to placeholder parameter number parameterIndex is element number parameterIndex -1.
Parameters:
  parameterIndex - the ordinal number of the placeholder parameter in this RowSet object's command that is to be set. The first parameter is 1, the second is 2, and so on; must be1 or greater
Parameters:
  array - an Array object representing an SQL ARRAY value; cannot be null. The Array objectpassed to this method must return a non-null Object for all getArray() method calls. A null value will cause aSQLException to be thrown.
throws:
  SQLException - if an error occurs; the parameter index is out of bounds or the ARRAY is null

When a very large ASCII value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream object. A JDBC technology-enabled driver will read the data from the stream as needed until it reaches end-of-file. The driver will do any necessary conversion from ASCII to the database CHAR format.

Note: This stream object can be either a standard Java stream object or your own subclass that implements the standard interface.

The parameter value set by this method is stored internally and will be supplied as the appropriate parameter in this RowSet object's command when the method execute is called. Methods such as execute and populate must be provided in any class that extends this class and implements one or more of the standard JSR-114 RowSet interfaces.

Note: JdbcRowSet does not require the populate method as it is undefined in this class.

Calls made to the method getParams after setAsciiStream has been called will return an array containing the parameter values that have been set. The element in the array that represents the values set with this method will itself be an array. The first element of that array is the given java.io.InputStream object. The second element is the value set for length. The third element is an internal BaseRowSet constant specifying that the stream passed to this method is an ASCII stream. The parameter number is indicated by an element's position in the array returned by the method getParams, with the first element being the value for the first placeholder parameter, the second element being the value for the second placeholder parameter, and so on. In other words, if the input stream being set is the value for the second placeholder parameter, the array containing it will be the second element in the array returned by getParams.

Note that because the numbering of elements in an array starts at zero, the array element that corresponds to placeholder parameter number parameterIndex is element number parameterIndex -1.
Parameters:
  parameterIndex - the ordinal number of the placeholder parameter in this RowSet object's command that is to be set. The first parameter is 1, the second is 2, and so on; must be1 or greater
Parameters:
  x - the Java input stream that contains the ASCII parameter value
Parameters:
  length - the number of bytes in the stream. This is the number of bytesthe driver will send to the DBMS; lengths of 0 or less are are undefined but will cause an invalid length exception to bethrown in the underlying JDBC driver.
throws:
  SQLException - if an error occurs, the parameter index is out of bounds,or when connected to a data source, the number of bytes the driver readsand sends to the database is not equal to the number of bytes specified in length
See Also:   BaseRowSet.getParams

When a very large binary value is input to a LONGVARBINARY parameter, it may be more practical to send it via a java.io.InputStream object. A JDBC technology-enabled driver will read the data from the stream as needed until it reaches end-of-file.

Note: This stream object can be either a standard Java stream object or your own subclass that implements the standard interface.

The parameter value set by this method is stored internally and will be supplied as the appropriate parameter in this RowSet object's command when the method execute is called. Methods such as execute and populate must be provided in any class that extends this class and implements one or more of the standard JSR-114 RowSet interfaces.

NOTE: JdbcRowSet does not require the populate method as it is undefined in this class.

Calls made to the method getParams after setBinaryStream has been called will return an array containing the parameter values that have been set. In that array, the element that represents the values set with this method will itself be an array. The first element of that array is the given java.io.InputStream object. The second element is the value set for length. The third element is an internal BaseRowSet constant specifying that the stream passed to this method is a binary stream. The parameter number is indicated by an element's position in the array returned by the method getParams, with the first element being the value for the first placeholder parameter, the second element being the value for the second placeholder parameter, and so on. In other words, if the input stream being set is the value for the second placeholder parameter, the array containing it will be the second element in the array returned by getParams.

When a very large Unicode value is input to a LONGVARCHAR parameter, it may be more practical to send it via a Reader object. A JDBC technology-enabled driver will read the data from the stream as needed until it reaches end-of-file. The driver will do any necessary conversion from Unicode to the database CHAR format. The byte format of the Unicode stream must be Java UTF-8, as defined in the Java Virtual Machine Specification.

Note: This stream object can be either a standard Java stream object or your own subclass that implements the standard interface.

The parameter value set by this method is stored internally and will be supplied as the appropriate parameter in this RowSet object's command when the method execute is called. Methods such as execute and populate must be provided in any class that extends this class and implements one or more of the standard JSR-114 RowSet interfaces.

NOTE: JdbcRowSet does not require the populate method as it is undefined in this class.

Calls made to the method getParams after setCharacterStream has been called will return an array containing the parameter values that have been set. In that array, the element that represents the values set with this method will itself be an array. The first element of that array is the given java.io.Reader object. The second element is the value set for length. The parameter number is indicated by an element's position in the array returned by the method getParams, with the first element being the value for the first placeholder parameter, the second element being the value for the second placeholder parameter, and so on. In other words, if the reader being set is the value for the second placeholder parameter, the array containing it will be the second element in the array returned by getParams.

Note that because the numbering of elements in an array starts at zero, the array element that corresponds to placeholder parameter number parameterIndex is element number parameterIndex -1.
Parameters:
  parameterIndex - the ordinal number of the placeholder parameter in this RowSet object's command that is to be set. The first parameter is 1, the second is 2, and so on; must be1 or greater
Parameters:

The parameter value set by this method is stored internally and will be supplied as the appropriate parameter in this RowSet object's command when the method execute is called. Methods such as execute and populate must be provided in any class that extends this class and implements one or more of the standard JSR-114 RowSet interfaces.

NOTE: JdbcRowSet does not require the populate method as it is undefined in this class.

Calls made to the method getParams after this version of setDate has been called will return an array with the value to be set for placeholder parameter number parameterIndex being the Date object supplied as the second parameter. Note that because the numbering of elements in an array starts at zero, the array element that corresponds to placeholder parameter number parameterIndex is parameterIndex -1.
Parameters:
  parameterIndex - the ordinal number of the placeholder parameter in this RowSet object's command that is to be set. The first parameter is 1, the second is 2, and so on; must be1 or greater
Parameters:

Methods such as execute and populate must be provided in any class that extends this class and implements one or more of the standard JSR-114 RowSet interfaces.

NOTE: JdbcRowSet does not require the populate method as it is undefined in this class.

Calls made to the method getParams after this version of setDate has been called will return an array containing the parameter values that have been set. In that array, the element that represents the values set with this method will itself be an array. The first element of that array is the given java.sql.Date object. The second element is the value set for cal. The parameter number is indicated by an element's position in the array returned by the method getParams, with the first element being the value for the first placeholder parameter, the second element being the value for the second placeholder parameter, and so on. In other words, if the date being set is the value for the second placeholder parameter, the array containing it will be the second element in the array returned by getParams.

Note that because the numbering of elements in an array starts at zero, the array element that corresponds to placeholder parameter number parameterIndex is parameterIndex -1.
Parameters:

throws:
  SQLException - if an error occurs setting the underlying JDBCtechnology-enabled driver to process the escape syntax

A RowSet object inherits the default properties of the ResultSet object from which it got its data. That ResultSet object's default fetch direction is set by the Statement object that created it.

This method applies to a RowSet object only while it is connected to a database using a JDBC driver.

A RowSet object may use this method at any time to change its setting for the fetch direction.
Parameters:
  direction - one of ResultSet.FETCH_FORWARD,ResultSet.FETCH_REVERSE, orResultSet.FETCH_UNKNOWN
throws:
  SQLException - if (1) the RowSet type is TYPE_FORWARD_ONLY and the given fetch direction is notFETCH_FORWARD or (2) the given fetch direction is notone of the following:ResultSet.FETCH_FORWARD,ResultSet.FETCH_REVERSE, orResultSet.FETCH_UNKNOWN
See Also:   BaseRowSet.getFetchDirection

A RowSet object inherits the default properties of the ResultSet object from which it got its data. That ResultSet object's default fetch size is set by the Statement object that created it.

This method applies to a RowSet object only while it is connected to a database using a JDBC driver. For connected RowSet implementations such as JdbcRowSet, this method has a direct and immediate effect on the underlying JDBC driver.

A RowSet object may use this method at any time to change its setting for the fetch size.

For RowSet implementations such as CachedRowSet, which operate in a disconnected environment, the SyncProvider object being used may leverage the fetch size to poll the data source and retrieve a number of rows that do not exceed the fetch size and that may form a subset of the actual rows returned by the original query. This is an implementation variance determined by the specific SyncProvider object employed by the disconnected RowSet object.

Parameters:
  rows - the number of rows to fetch; 0 to let thedriver decide what the best fetch size is; must not be lessthan 0 or more than the maximum number of rowsallowed for this RowSet object (the number returnedby a call to the method BaseRowSet.getMaxRows)
throws:
  SQLException - if the specified fetch size is less than 0or more than the limit for the maximum number of rows
See Also:   BaseRowSet.getFetchSize

Note that the second parameter tells the DBMS the data type of the value being set to NULL. Some DBMSs require this information, so it is required in order to make code more portable.

The parameter value set by this method is stored internally and will be supplied as the appropriate parameter in this RowSet object's command when the method execute is called. Methods such as execute and populate must be provided in any class that extends this class and implements one or more of the standard JSR-114 RowSet interfaces.

NOTE: JdbcRowSet does not require the populate method as it is undefined in this class.

Calls made to the method getParams after this version of setNull has been called will return an Object array containing the parameter values that have been set. In that array, the element that represents the values set with this method will itself be an array. The first element of that array is null. The second element is the value set for sqlType. The parameter number is indicated by an element's position in the array returned by the method getParams, with the first element being the value for the first placeholder parameter, the second element being the value for the second placeholder parameter, and so on. In other words, if the second placeholder parameter is being set to null, the array containing it will be the second element in the array returned by getParams.

Note that because the numbering of elements in an array starts at zero, the array element that corresponds to placeholder parameter number parameterIndex is parameterIndex -1.
Parameters:
  parameterIndex - the ordinal number of the placeholder parameter in this RowSet object's command that is to be set. The first parameter is 1, the second is 2, and so on; must be1 or greater
Parameters:
  sqlType - an int that is one of the SQL type codesdefined in the class java.sql.Types. If a non-standard sqlType is supplied, this method will not throw a SQLException. This allows implicit support for non-standard SQL types.
throws:
  SQLException - if a database access error occurs or the givenparameter index is out of bounds
See Also:   BaseRowSet.getParams

Note: To be portable, applications must give the SQL type code and the fully qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-defined type, the name is the type name of the parameter itself. For a REF parameter, the name is the type name of the referenced type. If a JDBC technology-enabled driver does not need the type code or type name information, it may ignore it.

If the parameter does not have a user-defined or REF type, the given typeName parameter is ignored.

The parameter value set by this method is stored internally and will be supplied as the appropriate parameter in this RowSet object's command when the method execute is called. Methods such as execute and populate must be provided in any class that extends this class and implements one or more of the standard JSR-114 RowSet interfaces.

NOTE: JdbcRowSet does not require the populate method as it is undefined in this class.

Calls made to the method getParams after this version of setNull has been called will return an Object array containing the parameter values that have been set.

The parameter number is indicated by an element's position in the array returned by the method getParams, with the first element being the value for the first placeholder parameter, the second element being the value for the second placeholder parameter, and so on. In other words, if the second placeholder parameter is being set to null, the array containing it will be the second element in the array returned by getParams.

Note that because the numbering of elements in an array starts at zero, the array element that corresponds to placeholder parameter number parameterIndex is parameterIndex -1.
Parameters:

Note: To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-defined type the name is the type name of the parameter itself. For a REF parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for user-defined and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the given typeName is ignored.
Parameters:
  parameterName - the name of the parameter
Parameters:
  sqlType - a value from java.sql.Types
Parameters:
  typeName - the fully-qualified name of an SQL user-defined type;ignored if the parameter is not a user-defined type orSQL REF value

The driver converts this object to the specified target SQL type before sending it to the database. If the object has a custom mapping (is of a class implementing SQLData), the driver should call the method SQLData.writeSQL to write the object to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, Struct, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

Note that this method may be used to pass database- specific abstract data types.

The parameter value set by this method is stored internally and will be supplied as the appropriate parameter in this RowSetexecute is called. Methods such as execute and populate must be provided in any class that extends this class and implements one or more of the standard JSR-114 RowSet interfaces.

NOTE: JdbcRowSet does not require the populate method as it is undefined in this class.

Calls made to the method getParams after this version of setObject has been called will return an array containing the parameter values that have been set. In that array, the element that represents the values set with this method will itself be an array. The first element of that array is the given Object instance, and the second element is the value set for targetSqlType. The third element is the value set for scale, which the driver will ignore if the type of the object being set is not java.sql.Types.NUMERIC or java.sql.Types.DECIMAL. The parameter number is indicated by an element's position in the array returned by the method getParams, with the first element being the value for the first placeholder parameter, the second element being the value for the second placeholder parameter, and so on. In other words, if the object being set is the value for the second placeholder parameter, the array containing it will be the second element in the array returned by getParams.

Note that because the numbering of elements in an array starts at zero, the array element that corresponds to placeholder parameter number parameterIndex is element number parameterIndex -1.
Parameters:
  parameterIndex - the ordinal number of the placeholder parameter in this RowSet object's command that is to be set. The first parameter is 1, the second is 2, and so on; must be1 or greater
Parameters:
  x - the Object containing the input parameter value;must be an Object type
Parameters:
  targetSqlType - the SQL type (as defined in java.sql.Types)to be sent to the database. The scale argument may further qualify this type. If a non-standard targetSqlTypeis supplied, this method will not throw a SQLException.This allows implicit support for non-standard SQL types.
Parameters:
  scale - for the types java.sql.Types.DECIMAL and java.sql.Types.NUMERIC, this is the numberof digits after the decimal point. For all other types, this value will be ignored.
throws:
  SQLException - if an error occurs or the parameter index is out of bounds

The JDBC specification defines a standard mapping from Java Object types to SQL types. The driver will use this standard mapping to convert the given object to its corresponding SQL type before sending it to the database. If the object has a custom mapping (is of a class implementing SQLData), the driver should call the method SQLData.writeSQL to write the object to the SQL data stream.

If, on the other hand, the object is of a class implementing Ref, Blob, Clob, Struct, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one interface.

Note that this method may be used to pass database-specific abstract data types.

The parameter value set by this method is stored internally and will be supplied as the appropriate parameter in this RowSet object's command when the method execute is called.

The JDBC specification specifies a standard mapping from Java Object types to SQL types. The given argument will be converted to the corresponding SQL type before being sent to the database.

Note that this method may be used to pass datatabase- specific abstract data types, by using a driver-specific Java type. If the object is of a class implementing the interface SQLData, the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, NClob, Struct, java.net.URL, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of the interfaces named above.
Parameters:
  parameterName - the name of the parameter
Parameters:
  x - the object containing the input parameter value
exception:
  SQLException - if a database access error occurs,this method is called on a closed CallableStatement or if the givenObject parameter is ambiguous

  parameterIndex - the ordinal number of the placeholder parameter in this RowSet object's command that is to be set. The first parameter is 1, the second is 2, and so on; must be1 or greater
Parameters:
  ref - a Ref object representing an SQL REF value; cannot be null
throws:
  SQLException - if an error occurs; the parameter index is out ofbounds or the Ref object is null; orthe Ref object returns a null base typename.

The parameter value set by this method is stored internally and will be supplied as the appropriate parameter in this RowSet object's command when the method execute is called. Methods such as execute and populate must be provided in any class that extends this class and implements one or more of the standard JSR-114 RowSet interfaces.

NOTE: JdbcRowSet does not require the populate method as it is undefined in this class.

Parameters:
  parameterIndex - the ordinal number of the placeholder parameter in this RowSet object's command that is to be set. The first parameter is 1, the second is 2, and so on; must be1 or greater
Parameters:
  x - the parameter value
throws:
  SQLException - if an error occurs or the parameter index is out of bounds
