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(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(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(String sqlToUse,
                                                                     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)
