hibernate的批量更新

String hqlUpdate = "update Customer c set c.name = :newName where c.name = :oldName";

int updatedEntities = s.createQuery( hqlUpdate )

.setString( "newName", newName )

.setString( "oldName", oldName )

.executeUpdate();





String hqlDelete = "delete Customer c where c.name = :oldName";

int deletedEntities = s.createQuery( hqlDelete )

.setString( "oldName", oldName )

.executeUpdate();



这种方法的批量更新确实不错。
