All Implemented Interfaces:

InitializingBean

Direct Known Subclasses:

SqlQuery, SqlUpdate

public abstract class SqlOperation
extends RdbmsOperation

Operation object representing a SQL-based operation such as a query or update, as opposed to a stored procedure.

Configures a PreparedStatementCreatorFactory based on the declared parameters.

Method Detail

compileInternal

protected final void compileInternal()

Overridden method to configure the PreparedStatementCreatorFactory based on our declared parameters.

Specified by:

compileInternal in class RdbmsOperation

onCompileInternal

protected void onCompileInternal()

Hook method that subclasses may override to post-process compilation. This implementation does nothing.

See Also:

compileInternal()

getParsedSql

protected ParsedSql getParsedSql()

Obtain a parsed representation of this operation's SQL statement.

Typically used for named parameter parsing.

newPreparedStatementSetter

protected final PreparedStatementSetter newPreparedStatementSetter(java.lang.Object[] params)

Return a PreparedStatementSetter to perform an operation with the given parameters.

Parameters:

params - the parameter array (may be null)

newPreparedStatementCreator

protected final PreparedStatementCreator newPreparedStatementCreator(java.lang.Object[] params)

Return a PreparedStatementCreator to perform an operation with the given parameters.

Parameters:

params - the parameter array (may be null)

newPreparedStatementCreator

protected final PreparedStatementCreator newPreparedStatementCreator(java.lang.String sqlToUse,
                                                                     java.lang.Object[] params)

Return a PreparedStatementCreator to perform an operation with the given parameters.

Parameters:

sqlToUse - the actual SQL statement to use (if different from the factory's, for example because of named parameter expanding)

params - the parameter array (may be null)
