Methods

Modifier and Type	Method and Description
void	initializeJdbcConnection(JdbcConnectionDescriptor jcd, java.sql.Connection conn) Called immediately after a JDBC connection has been created by a ConnectionFactory implementation (not used for DataSource connections).
java.sql.CallableStatement	prepareNextValProcedureStatement(java.sql.Connection con, java.lang.String procedureName, java.lang.String sequenceName) Create stored procedure call for a special sequence manager implementation SequenceManagerStoredProcedureImpl, because it seems that jdbc-driver differ in handling of CallableStatement.

initializeJdbcConnection

public void initializeJdbcConnection(JdbcConnectionDescriptor jcd,
                            java.sql.Connection conn)
                              throws PlatformException

Description copied from interface: Platform

Called immediately after a JDBC connection has been created by a ConnectionFactory implementation (not used for DataSource connections).

Specified by:

initializeJdbcConnection in interface Platform

Overrides:

initializeJdbcConnection in class PlatformDefaultImpl

conn - the Connection to be initialized

Throws:

PlatformException

prepareNextValProcedureStatement

                                                            throws PlatformException

Description copied from interface: Platform

Create stored procedure call for a special sequence manager implementation SequenceManagerStoredProcedureImpl, because it seems that jdbc-driver differ in handling of CallableStatement.
Note: The out-parameter of the stored procedure must be registered at first position, because lookup for new long id in the implementation:

 Connection con = broker.serviceConnectionManager().getConnection();
 cs = getPlatform().prepareNextValProcedureStatement(con, PROCEDURE_NAME, sequenceName);
 cs.executeUpdate();
 return cs.getLong(1);
 

Specified by:

prepareNextValProcedureStatement in interface Platform

Overrides:

prepareNextValProcedureStatement in class PlatformDefaultImpl

Throws:

PlatformException
