| addBatch | | public void addBatch(String sql) throws DatabaseException(Code) | | Adds the given SQL command to the current list of commmands for this
Statement object. The commands in this list can be
executed as a batch by calling the method executeBatch.
If an exception is thrown, this DbStatement is
automatically closed and an ongoing transaction will be automatically
rolled back if it belongs to the executing thread.
Parameters:
sql - typically this is a static SQL INSERT orUPDATE statement

| clone | | public Object clone()(Code) | | Simply clones the instance with the default clone method. This creates
a shallow copy of all fields and the clone will in fact just be another
reference to the same underlying data. The independence of each cloned
instance is consciously not respected since they rely on resources that
can't be cloned.
since:
1.0 |
| close | | public void close() throws DatabaseException(Code) | | Releases this DbStatement object's database and JDBC
resources immediately instead of waiting for this to happen when it is
automatically closed. It is generally good practice to release
resources as soon as you are finished with them to avoid tying up
database resources.
Calling the method close on a DbStatement
object that is already closed has no effect.
Note: A DbStatement object is automatically
closed when it is garbage collected. When a DbStatement
object is closed, its current ResultSet object, if one
exists, is also closed.

| execute | | public boolean execute(String sql) throws DatabaseException(Code) | | Executes the given SQL statement, which may return multiple results. In
some (uncommon) situations, a single SQL statement may return multiple
result sets and/or update counts. Normally you can ignore this unless
you are (1) executing a stored procedure that you know may return
multiple results or (2) you are dynamically executing an unknown SQL
string.
The execute method executes a SQL statement and
indicates the form of the first result. You must then use the methods
getResultSet or getUpdateCount to retrieve
the result, and getMoreResults to move to any subsequent
result(s).
If an exception is thrown, this DbStatement is
automatically closed and an ongoing transaction will be automatically
rolled back if it belongs to the executing thread.
Parameters:
sql - any SQL statement true if the first result is aResultSet object; or false if it is an update count or there are no results

| executeBatch | | public int[] executeBatch() throws DatabaseException(Code) | | Submits a batch of commands to the database for execution and if all
commands execute successfully, returns an array of update counts. The
int elements of the array that is returned are ordered to
correspond to the commands in the batch, which are ordered according to
the order in which they were added to the batch. The elements in the
array returned by the method executeBatch may be one of
the following:
- A number greater than or equal to zero -- indicates that the
command was processed successfully and is an update count giving the
number of rows in the database that were affected by the command's
execution
- A value of
SUCCESS_NO_INFO -- indicates that the
command was processed successfully but that the number of rows affected
is unknown
If one of the commands in a batch update fails to execute properly,
this method throws a BatchUpdateException, and a JDBC
driver may or may not continue to process the remaining commands in the
batch. However, the driver's behavior must be consistent with a
particular DBMS, either always continuing to process commands or never
continuing to process commands. If the driver continues processing
after a failure, the array returned by the method
BatchUpdateException.getUpdateCounts will contain as many
elements as there are commands in the batch, and at least one of the
elements will be the following:
- A value of
EXECUTE_FAILED -- indicates that the
command failed to execute successfully and occurs only if a driver
continues to process commands after a command fails
A driver is not required to implement this method.
If an exception is thrown, this DbStatement is
automatically closed and an ongoing transaction will be automatically
rolled back if it belongs to the executing thread.
an array of update counts containing one element for eachcommand in the batch. The elements of the array are ordered accordingto the order in which commands were added to the batch.
exception:
DatabaseException - if a database access error occurs or thedriver does not support batch statements. The cause is a java.sql.BatchUpdateException (a subclass of SQLException)if one of the commands sent to the database fails to execute properlyor attempts to return a result set.

specified affects only result sets created using this statement. If the
value specified is zero, then the hint is ignored. The default value is
zero.
If an exception is thrown, this DbStatement is
automatically closed and an ongoing transaction will be automatically
rolled back if it belongs to the executing thread.
Parameters:
rows - the number of rows to fetch
exception:
DatabaseException - if a database access error occurs, or thecondition 0 <= rows <=this.getMaxRows() is not satisfied.

| setMaxFieldSize | | public void setMaxFieldSize(int max) throws DatabaseException(Code) | | Sets the limit for the maximum number of bytes in a
ResultSet column storing character or binary values to the
given number of bytes. This limit applies only to BINARY,
VARBINARY, LONGVARBINARY, CHAR,
VARCHAR, and LONGVARCHAR fields. If the limit
is exceeded, the excess data is silently discarded. For maximum
portability, use values greater than 256.
If an exception is thrown, this DbStatement is
automatically closed and an ongoing transaction will be automatically
rolled back if it belongs to the executing thread.
Parameters:
max - the new column size limit in bytes; zero means there is nolimit
exception:
DatabaseException - if a database access error occurs or thecondition max >= 0 is not satisfied

1.0 |
| setMaxRows | | public void setMaxRows(int max) throws DatabaseException(Code) | | Sets the limit for the maximum number of rows that any
ResultSet object can contain to the given number. If the
limit is exceeded, the excess rows are silently dropped.
If an exception is thrown, this DbStatement is
automatically closed and an ongoing transaction will be automatically
rolled back if it belongs to the executing thread.
Parameters:
max - the new max rows limit; zero means there is no limit
exception:
DatabaseException - if a database access error occurs or thecondition max >= 0 is not satisfied

| setQueryTimeout | | public void setQueryTimeout(int max) throws DatabaseException(Code) | | Sets the number of seconds the driver will wait for a
DbStatement object to execute to the given number of
seconds. If the limit is exceeded, an DatabaseException is
thrown.
Parameters:
max - the new query timeout limit in seconds; zero means there isno limit
exception:
DatabaseException - if a database access error occurs or thecondition seconds >= 0 is not satisfied

| setResultset | | protected void setResultset(ResultSet resultSet) throws DatabaseException(Code) | | Set the current ResultSet object and cleans up the
previous ResultSet object automatically.
Parameters:
resultSet - the new current ResultSet object
exception:
DatabaseException - if a database access error occurred.

| startTrace | | protected long startTrace()(Code) | | |
| waitForConnection | | void waitForConnection() throws DatabaseException(Code) | | Waits until the DbConnection method is available for use.
This method is used by all the execution methods to effectively
integrate with the connection pool.
exception:
DatabaseException - when a database access error occurs or theconnection isn't open or has timed-out
since:

| wasNull | | public boolean wasNull() throws DatabaseException(Code) | | Reports whether the last column read had a value of SQL
NULL. Note that you must first call one of the getter
methods on a column to try to read its value and then call the method
wasNull to see if the value read was SQL NULL.
If an exception is thrown, this DbStatement is
automatically closed and an ongoing transaction will be automatically
rolled back if it belongs to the executing thread.
true if the last column value read was SQLNULL; or false otherwise
exception:
DatabaseException - if a database access error occurs
