Parameters:

resultSetType - the ResultSet type

See Also:

ResultSet.TYPE_FORWARD_ONLY, ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.TYPE_SCROLL_SENSITIVE

---

setUpdatableResults

public void setUpdatableResults(boolean updatableResults)

Set whether to use prepared statements capable of returning updatable ResultSets.

---

setReturnGeneratedKeys

public void setReturnGeneratedKeys(boolean returnGeneratedKeys)

---

setNativeJdbcExtractor

public void setNativeJdbcExtractor(NativeJdbcExtractor nativeJdbcExtractor)

Specify the NativeJdbcExtractor to use for unwrapping PreparedStatements, if any.

---

newPreparedStatementSetter

public PreparedStatementSetter newPreparedStatementSetter(List params)

Return a new PreparedStatementSetter for the given parameters.

Parameters:

params - List of parameters (may be null)

---

newPreparedStatementSetter

public PreparedStatementSetter newPreparedStatementSetter(Object[] params)

Return a new PreparedStatementSetter for the given parameters.

Parameters:

params - the parameter array (may be null)

---

newPreparedStatementCreator

public PreparedStatementCreator newPreparedStatementCreator(List params)

Return a new PreparedStatementCreator for the given parameters.

Parameters:
