Interface StatementEventListener
- All Superinterfaces:
- EventListener
 The JDBC 3.0 specification added the maxStatements
 ConnectionPooledDataSource property to provide a standard mechanism for
 enabling the pooling of PreparedStatements
 and to specify the size of the statement
 pool.  However, there was no way for a driver to notify an external
 statement pool when a PreparedStatement becomes invalid.  For some databases, a
 statement becomes invalid if a DDL operation is performed that affects the
 table.  For example an application may create a temporary table to do some work
 on the table and then destroy it.  It may later recreate the same table when
 it is needed again.  Some databases will invalidate any prepared statements
 that reference the temporary table when the table is dropped.
 
 Similar to the methods defined in the ConnectionEventListener interface,
 the driver will call the StatementEventListener.statementErrorOccurred
 method prior to throwing any exceptions when it detects a statement is invalid.
 The driver will also call the StatementEventListener.statementClosed
 method when a PreparedStatement is closed.
 
 Methods which allow a component to register a StatementEventListener with a
 PooledConnection have been added to the PooledConnection interface.

Method Details- 
statementClosedThe driver calls this method on allStatementEventListeners registered on the connection when it detects that aPreparedStatementis closed.- Parameters:
- event- an event object describing the source of the event and that the- PreparedStatementwas closed.

statementErrorOccurredThe driver calls this method on allStatementEventListeners registered on the connection when it detects that aPreparedStatementis invalid. The driver calls this method just before it throws theSQLException, contained in the given event, to the application.- Parameters:
- event- an event object describing the source of the event, the statement that is invalid and the exception the driver is about to throw. The source of the event is the- PooledConnectionwhich the invalid- PreparedStatementis associated with.
