Statement 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 Statement object that is already
closed has no effect.
Note:When a Statement object is closed, its current ResultSet
object, if one exists, is also closed.

The Connection and DataSource property escapeProcessing may be used
to change the default escape processing behavior. A value of true (the default) enables escape
Processing for all Statement objects. A value of false disables escape processing for
all Statement objects. The setEscapeProcessing method may be used to specify
the escape processing behavior for an individual Statement object.
Note: Since prepared statements have usually been parsed prior to making this call,
disabling escape processing for PreparedStatements objects will have no effect.

StatementsetQueryTimeout(int)public void setQueryTimeout(int seconds)
throws SQLException
Statement object to execute
to the given number of seconds. By default there is no limit on the amount of time allowed for
a running statement to complete. If the limit is exceeded, an SQLTimeoutException
is thrown. A JDBC driver must apply this limit to the execute, executeQuery
and executeUpdate methods.
Note: JDBC driver implementations may also apply this limit to ResultSet methods (consult your driver vendor documentation for details).
Note: In the case of Statement batching, it is implementation
defined as to whether the time-out is applied to individual SQL commands added via the addBatch method or to the entire batch of SQL commands invoked by the executeBatch
method (consult your driver vendor documentation for details).

StatementSQLFeatureNotSupportedException - if the JDBC driver does not support this methodpublic SQLWarning getWarnings() throws SQLException
Statement object. Subsequent
Statement object warnings will be chained to this SQLWarning object.
The warning chain is automatically cleared each time a statement is (re)executed. This
method may not be called on a closed Statement object; doing so will cause an
SQLException to be thrown.
Note: If you are processing a ResultSet object, any warnings associated
with reads on that ResultSet object will be chained on it rather than on the
Statement object that produced it.
getWarnings in interface StatementSQLWarning object or null if there are no warningsSQLException - if a database access error occurs or this method is called on a closed

String, which will be used by subsequent
Statement object execute methods. This name can then be used in SQL
positioned update or delete statements to identify the current row in the ResultSet
object generated by this statement. If the database does not support positioned
update/delete, this method is a noop. To insure that a cursor has the proper isolation level to
support updates, the cursor's SELECT statement should have the form
SELECT FOR UPDATE. If FOR UPDATE is not present, positioned updates may
fail.
Note: By definition, the execution of positioned updates and deletes must be done by
a different Statement object than the one that generated the ResultSet
object being used for positioning. Also, cursor names must be unique within a
connection.

The execute method executes an 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).

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:
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:
EXECUTE_FAILED -- indicates that the command failed to execute
successfully and occurs only if a driver continues to process commands after a command
fails
The possible implementations and return values have been modified in the Java 2 SDK,
Standard Edition, version 1.3 to accommodate the option of continuing to process commands in a
batch update after a BatchUpdateException object has been thrown.

INSERT statement, or an SQL statement able to return
auto-generated keys (the list of such statements is vendor-specific).
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 an 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).
Note:This method cannot be called on a PreparedStatement or
CallableStatement.

Statement be pooled or not pooled. The value specified is a hint
to the statement pool implementation indicating whether the application wants the statement to
be pooled. It is up to the statement pool manager as to whether the hint is used.
The poolable value of a statement is applicable to both internal statement caches implemented by the driver and external statement caches implemented by application servers and other applications.
By default, a Statement is not poolable when created, and a
PreparedStatement and CallableStatement are poolable when created.

Statement will be closed when all its dependent result sets are
closed. If execution of the Statement does not produce any result sets, this method has
no effect.
Note: Multiple calls to closeOnCompletion do not toggle the effect
on this Statement. However, a call to closeOnCompletion does effect both the
subsequent execution of statements, and statements that currently have open, dependent, result
sets.

If the receiver implements the interface then the result is the receiver or a proxy for the
receiver. If the receiver is a wrapper and the wrapped object implements the interface then the
result is the wrapped object or a proxy for the wrapped object. Otherwise return the the result
of calling unwrap recursively on the wrapped object or a proxy for that result. If
the receiver is not a wrapper and does not implement the interface, then an SQLException
is thrown.
