| jdbcResultSet | | public class jdbcResultSet implements ResultSet(Code) | |
A table of data representing a database result set, which
is usually generated by executing a statement that queries the database.
A ResultSet object maintains a cursor pointing
to its current row of data. Initially the cursor is positioned
before the first row. The next method moves the
cursor to the next row, and because it returns false
when there are no more rows in the ResultSet object,
it can be used in a while loop to iterate through
the result set.
A default ResultSet object is not updatable and
has a cursor that moves forward only. Thus, you can
iterate through it only once and only from the first row to the
last row. It is possible to
produce ResultSet objects that are scrollable and/or
updatable. The following code fragment, in which con
is a valid Connection object, illustrates how to make
a result set that is scrollable and insensitive to updates by others,
and that is updatable. See ResultSet fields for other
options.
Statement stmt = con.createStatement(
ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_UPDATABLE);
ResultSet rs = stmt.executeQuery("SELECT a, b FROM TABLE2");
// rs will be scrollable, will not show changes made by others,
// and will be updatable
The ResultSet interface provides
getter methods (getBoolean, getLong,
and so on) for retrieving column values from the current row.
Values can be retrieved using either the index number of the
column or the name of the column. In general, using the
column index will be more efficient. Columns are numbered from 1.
For maximum portability, result set columns within each row should be
read in left-to-right order, and each column should be read only once.
For the getter methods, a JDBC driver attempts
to convert the underlying data to the Java type specified in the
getter method and returns a suitable Java value. The JDBC specification
has a table showing the allowable mappings from SQL types to Java types
that can be used by the ResultSet getter methods.
Column names used as input to getter methods are case
insensitive. When a getter method is called with
a column name and several columns have the same name,
the value of the first matching column will be returned.
The column name option is
designed to be used when column names are used in the SQL
query that generated the result set.
For columns that are NOT explicitly named in the query, it
is best to use column numbers. If column names are used, there is
no way for the programmer to guarantee that they actually refer to
the intended columns.
A set of updater methods were added to this interface
in the JDBC 2.0 API (JavaTM 2 SDK,
Standard Edition, version 1.2). The comments regarding parameters
to the getter methods also apply to parameters to the
updater methods.
The updater methods may be used in two ways:
- to update a column value in the current row. In a scrollable
ResultSet object, the cursor can be moved backwards
and forwards, to an absolute position, or to a position
relative to the current row.
The following code fragment updates the NAME column
in the fifth row of the ResultSet object
rs and then uses the method updateRow
to update the data source table from which rs was
derived.
rs.absolute(5); // moves the cursor to the fifth row of rs
rs.updateString("NAME", "AINSWORTH"); // updates the
// NAME column of row 5 to be AINSWORTH
rs.updateRow(); // updates the row in the data source
- to insert column values into the insert row. An updatable
ResultSet object has a special row associated with
it that serves as a staging area for building a row to be inserted.
The following code fragment moves the cursor to the insert row, builds
a three-column row, and inserts it into rs and into
the data source table using the method insertRow.
rs.moveToInsertRow(); // moves cursor to the insert row
rs.updateString(1, "AINSWORTH"); // updates the
// first column of the insert row to be AINSWORTH
rs.updateInt(2,35); // updates the second column to be 35
rs.updateBoolean(3, true); // updates the third row to true
rs.insertRow();
rs.moveToCurrentRow();
A ResultSet object is automatically closed when the
Statement object that
generated it is closed, re-executed, or used
to retrieve the next result from a sequence of multiple results.
The number, types and properties of a ResultSet
object's columns are provided by the ResulSetMetaData
object returned by the ResultSet.getMetaData method.
HSQLDB-Specific Information:
A ResultSet object generated by HSQLDB is by default of
ResultSet.TYPE_FORWARD_ONLY (as is standard JDBC behavior)
and does not allow the use of absolute and relative positioning
methods. However, since 1.7.0, if a statement is created
with:
Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
then the ResultSet objects it produces support
using all of the absolute and relative positioning methods of JDBC2
to set the position of the current row, for example:
rs.absolute(5);
String fifthRowValue = rs.getString(1);
rs.relative(4);
String ninthRowValue = rs.getString(1);
Note: An HSQLDB ResultSet object persists, even after its
connection is closed. This is regardless of the operational mode of
the
Database Database from which it came. That is, they
persist whether originating from a Server,
WebServer or in-process mode Database.
Including HSQLDB 1.7.2, there is no support for any of the methods
introduced in JDBC 2 relating to updateable result sets. These methods
include all updateXXX methods, as well as the
jdbcResultSet.insertRow ,
jdbcResultSet.updateRow ,
jdbcResultSet.deleteRow ,
jdbcResultSet.moveToInsertRow (and so on)
methods; invoking any such method throws an SQLException
stating that the operation is not supported.
JRE 1.1.x Notes:
In general, JDBC 2 support requires Java 1.2 and above, and JDBC 3 requires
Java 1.4 and above. In HSQLDB, support for methods introduced in different
versions of JDBC depends on the JDK version used for compiling and building
HSQLDB.
Since 1.7.0, it is possible to build the product so that
all JDBC 2 methods can be called while executing under the version 1.1.x
Java Runtime EnvironmentTM.
However, some of these method calls require int values that
are defined only in the JDBC 2 or greater version of the
ResultSet interface. For this reason, when the
product is compiled under JDK 1.1.x, these values are defined here, in this
class.
In a JRE 1.1.x environment, calling JDBC 2 methods that take or return the
JDBC2-only ResultSet values can be achieved by referring
to them in parameter specifications and return value comparisons,
respectively, as follows:
jdbcResultSet.FETCH_FORWARD
jdbcResultSet.TYPE_FORWARD_ONLY
jdbcResultSet.TYPE_SCROLL_INSENSITIVE
jdbcResultSet.CONCUR_READ_ONLY
// etc.
However, please note that code written in such a manner will not be
compatible for use with other JDBC 2 drivers, since they expect and use
ResultSet, rather than jdbcResultSet. Also
note, this feature is offered solely as a convenience to developers
who must work under JDK 1.1.x due to operating constraints, yet wish to
use some of the more advanced features available under the JDBC 2
specification.

| absolute | | public boolean absolute(int row) throws SQLException(Code) | |
Moves the cursor to the given row number in
this ResultSet object.
If the row number is positive, the cursor moves to
the given row number with respect to the
beginning of the result set. The first row is row 1, the second
is row 2, and so on.

| getAsciiStream | | public java.io.InputStream getAsciiStream(int columnIndex) throws SQLException(Code) | |
Retrieves the value of the designated column in the current row
of this ResultSet object as
a stream of ASCII characters. The value can then be read in chunks
from the stream. This method is particularly
suitable for retrieving large LONGVARCHAR values.
The JDBC driver will
do any necessary conversion from the database format into ASCII.
Note: All the data in the returned stream must be
read prior to getting the value of any other column. The next
call to a getter method implicitly closes the stream. Also, a
stream may return 0 when the method
InputStream.available
is called whether there is data available or not.
HSQLDB-Specific Information:
The limitation noted above does not apply to HSQLDB.
In 1.6.1 and previous, getAsciiStream was identical to
getUnicodeStream and both simply returned a byte stream
constructed from the raw
jdbcResultSet.getBytes(int) getBytes representation.
Starting with 1.7.0, this has been updated to comply with the
java.sql specification.
When the column is of type CHAR and its variations, it requires no
conversion since it is represented internally already as a
Java String object. When the column is not of type CHAR and its
variations, the returned stream is based on a conversion to the
Java String representation of the value. In either case,
the obtained stream is always equivalent to a stream of the low order
bytes from the value's String representation.
HSQLDB SQL CHAR and its variations are all Unicode strings
internally, so the recommended alternatives to this method are
jdbcResultSet.getString(int) getString ,
jdbcResultSet.getUnicodeStream(int) getUnicodeStream (deprecated)
and new to 1.7.0:
jdbcResultSet.getCharacterStream(int) getCharacterStream (now prefered over the deprecated getUnicodeStream alternative).
Parameters:
columnIndex - the first column is 1, the second is 2, ... a Java input stream that delivers the database column valueas a stream of one-byte ASCII characters;if the value is SQL NULL, thevalue returned is null
exception:
SQLException - if a database access error occurs |
| getAsciiStream | | public java.io.InputStream getAsciiStream(String columnName) throws SQLException(Code) | |
Retrieves the value of the designated column in the current row
of this ResultSet object as a stream of
ASCII characters. The value can then be read in chunks from the
stream. This method is particularly
suitable for retrieving large LONGVARCHAR values.
The JDBC driver will
do any necessary conversion from the database format into ASCII.
Note: All the data in the returned stream must be
read prior to getting the value of any other column. The next
call to a getter method implicitly closes the stream. Also, a
stream may return 0 when the method available
is called whether there is data available or not.
Parameters:
columnName - the SQL name of the column a Java input stream that delivers the database column valueas a stream of one-byte ASCII characters.If the value is SQL NULL,the value returned is null.

HSQLDB-Specific Information:
Example:
The following code fragment creates a ResultSet object rs,
creates a ResultSetMetaData object rsmd, and uses rsmd
to find out how many columns rs has and whether the first column
in rs can be used in a WHERE clause.
ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2");
ResultSetMetaData rsmd = rs.getMetaData();
int numberOfColumns = rsmd.getColumnCount();
boolean b = rsmd.isSearchable(1);
Warning:
Including 1.7.1, HSQLDB did not generate accurate
ResultSetMetaData. Below were the the most important
methods to consider:
- isAutoIncrement(int) always returned
false
- isCurrency(int) always returned
false
- isNullable(int) always returned
columnNullableUnknown
- getColumnDisplaySize(int) returned zero for all valid column
numbers
- getSchemaName(int) always returned
""
- getPrecision(int) always returned zero
- getScale(int) always returned zero
- getCatalogName(int) always returned
""
Starting with 1.7.2, ResultSetMetaData has been split out into its own
interface implemenation (jdbcResultSetMetaData), support has been
improved considerably for a number of methods and behaviour has
been altered slightly in many areas.

| getObject | | public Object getObject(int columnIndex) throws SQLException(Code) | |
Gets the value of the designated column in the current row
of this ResultSet object as
an Object in the Java programming language.
This method will return the value of the given column as a
Java object. The type of the Java object will be the default
Java object type corresponding to the column's SQL type,
following the mapping for built-in types specified in the JDBC
specification. If the value is an SQL NULL,
the driver returns a Java null.
This method may also be used to read datatabase-specific
abstract data types.
In the JDBC 2.0 API, the behavior of method
getObject is extended to materialize
data of SQL user-defined types. When a column contains
a structured or distinct value, the behavior of this method is as
if it were a call to: getObject(columnIndex,
this.getStatement().getConnection().getTypeMap()).

| getUnicodeStream | | public java.io.InputStream getUnicodeStream(int columnIndex) throws SQLException(Code) | |
Retrieves the value of the designated column in the current row
of this ResultSet object as
as a stream of two-byte Unicode characters. The first byte is
the high byte; the second byte is the low byte.
The value can then be read in chunks from the
stream. This method is particularly
suitable for retrieving large LONGVARCHARvalues. The
JDBC driver will do any necessary conversion from the database
format into Unicode.
Note: All the data in the returned stream must be
read prior to getting the value of any other column. The next
call to a getter method implicitly closes the stream.
Also, a stream may return 0 when the method
InputStream.available
is called, whether there is data available or not.
HSQLDB-Specific Information:
The limitation noted above does not apply to HSQLDB.
Up to and including 1.6.1, getUnicodeStream (and getAsciiStream)
both simply returned a byte stream constructed from the
raw
jdbcResultSet.getBytes(int) getBytes representation.
Starting with 1.7.0, this has been corrected to comply with the
java.sql specification.
When the column is of type CHAR and its variations, it requires no
conversion since it is represented internally already as
Java Strings. When the column is not of type CHAR and its variations,
the returned stream is based on a conversion to the
Java String representation of the value. In either case,
the obtained stream is always equivalent to a stream of
bytes from the value's String representation, with high-byte first.
Parameters:
columnIndex - the first column is 1, the second is 2, ... a Java input stream that delivers the database column valueas a stream of two-byte Unicode characters;if the value is SQL NULL, the value returned isnull
exception:
SQLException - if a database access error occurs |
| getUnicodeStream | | public java.io.InputStream getUnicodeStream(String columnName) throws SQLException(Code) | |
Retrieves the value of the designated column in the current row
of this ResultSet object as a stream of two-byte
Unicode characters. The first byte is the high byte; the second
byte is the low byte.
The value can then be read in chunks from the
stream. This method is particularly
suitable for retrieving large LONGVARCHAR values.
The JDBC technology-enabled driver will
do any necessary conversion from the database format into Unicode.
Note: All the data in the returned stream must be
read prior to getting the value of any other column. The next
call to a getter method implicitly closes the stream.
Also, a stream may return 0 when the method
InputStream.available is called, whether there
is data available or not.
Parameters:
columnName - the SQL name of the column a Java input stream that delivers the database column valueas a stream of two-byte Unicode characters.If the value is SQL NULL, the value returnedis null.

| getWarnings | | public SQLWarning getWarnings() throws SQLException(Code) | |
Retrieves the first warning reported by calls on this
ResultSet object.
Subsequent warnings on this ResultSet object
will be chained to the SQLWarning object that
this method returns.
The warning chain is automatically cleared each time a new
row is read. This method may not be called on a ResultSet
object that has been closed; doing so will cause an
SQLException to be thrown.
Note: This warning chain only covers warnings caused
by ResultSet methods. Any warning caused by
Statement methods
(such as reading OUT parameters) will be chained on the
Statement object.
HSQLDB-Specific Information:

| isLast | | public boolean isLast() throws SQLException(Code) | |
Retrieves whether the cursor is on the last row of
this ResultSet object.
Note: Calling the method isLast may be expensive
because the JDBC driver
might need to fetch ahead one row in order to determine
whether the current row is the last row in the result set.

| moveToInsertRow | | public void moveToInsertRow() throws SQLException(Code) | |
Moves the cursor to the insert row. The current cursor position is
remembered while the cursor is positioned on the insert row.
The insert row is a special row associated with an updatable
result set. It is essentially a buffer where a new row may
be constructed by calling the updater methods prior to
inserting the row into the result set.
Only the updater, getter,
and insertRow methods may be
called when the cursor is on the insert row. All of the columns in
a result set must be given a value each time this method is
called before calling insertRow.
An updater method must be called before a
getter method can be called on a column value.
HSQLDB-Specific Information:
Including 1.7.2, HSQLDB does not support updateable result sets.
This method always throws an SQLException stating that
the operation is not supported.

| next | | public boolean next() throws SQLException(Code) | |
Moves the cursor down one row from its current position.
A ResultSet cursor is initially positioned
before the first row; the first call to the method
next makes the first row the current row; the
second call makes the second row the current row, and so on.
If an input stream is open for the current row, a call
to the method next will
implicitly close it. A ResultSet object's
warning chain is cleared when a new row is read.

| refreshRow | | public void refreshRow() throws SQLException(Code) | |
Refreshes the current row with its most recent value in
the database. This method cannot be called when
the cursor is on the insert row.
The refreshRow method provides a way for an
application to
explicitly tell the JDBC driver to refetch a row(s) from the
database. An application may want to call refreshRow when
caching or prefetching is being done by the JDBC driver to
fetch the latest value of a row from the database. The JDBC driver
may actually refresh multiple rows at once if the fetch size is
greater than one.
All values are refetched subject to the transaction isolation
level and cursor sensitivity. If refreshRow is called
after calling an updater method, but before calling

| relative | | public boolean relative(int rows) throws SQLException(Code) | |
Moves the cursor a relative number of rows, either positive or
negative. Attempting to move beyond the first/last row in the
result set positions the cursor before/after the
the first/last row. Calling relative(0) is valid, but does
not change the cursor position.
Note: Calling the method relative(1)
is identical to calling the method next() and
calling the method relative(-1) is identical
to calling the method previous().
