Method Detail

prepare

public java.sql.PreparedStatement prepare(java.lang.String sql,
                                          java.sql.Connection connection)
                                   throws java.sql.SQLException,
                                          PersistenceException

Description copied from interface: IPreparedStatementManager

Returns a PreparedStatement prepared from the SQL and the connection. Implement this method if the default implementation in PreparedStatementManagerBase doesn't match your needs. For instance, if you need to call a different Connection.prepare(...) method.

Specified by:

prepare in interface IPreparedStatementManager

Parameters:

sql - The SQL to prepare the PreparedStatement for.

connection - The connection to use to prepare the PreparedStatement.

Returns:

A PreparedStatement.

Throws:

java.sql.SQLException - If the preparation fails.

PersistenceException - If something else goes wrong during the prepare method.

init

public void init(java.sql.PreparedStatement statement)
          throws java.sql.SQLException,
                 PersistenceException

Description copied from interface: IPreparedStatementManager

Initializes the PreparedStatement. Typicially this means setting the correct parameters on the statement (setString(1, "value"), setLong(1, 45) etc.).

Specified by:

init in interface IPreparedStatementManager

Parameters:

statement - The PreparedStatement to initialize.

Throws:

java.sql.SQLException - If the initialization fails in the JDBC driver.

PersistenceException - If something else goes wrong during initialization.

execute

public java.lang.Object execute(java.sql.PreparedStatement statement)
                         throws java.sql.SQLException,
                                PersistenceException

Description copied from interface: IPreparedStatementManager

Executes the PreparedStatement.

Specified by:

execute in interface IPreparedStatementManager

Parameters:

statement - The PreparedStatement to execute.

Returns:

The result of the execute() method. For instance a ResultSet.

Throws:

java.sql.SQLException - If the executing fails.

PersistenceException - If something else fails during execution.

postProcess

public void postProcess(java.sql.PreparedStatement statement)
                 throws java.sql.SQLException,
                        PersistenceException

Description copied from interface: IPreparedStatementManager

Post processes the PreparedStatement after execution. Typically post processing will be reading of generated id's. You do not need to close the PreparedStatement in this method.

Specified by:

postProcess in interface IPreparedStatementManager

Parameters:

statement - The PreparedStatement to post process.

Throws:

java.sql.SQLException - If post processing fails in the driver.

PersistenceException - If something else fails during post processing.
