PHP Criteria::getComment方法代码示例

 /**
  * Method used to update rows in the DB.  Rows are selected based
  * on selectCriteria and updated using values in updateValues.
  * <p>
  * Use this method for performing an update of the kind:
  * <p>
  * WHERE some_column = some value AND could_have_another_column =
  * another value AND so on.
  *
  * @param      $selectCriteria A Criteria object containing values used in where
  *		clause.
  * @param      $updateValues A Criteria object containing values used in set
  *		clause.
  * @param      PropelPDO $con The PropelPDO connection object to use.
  * @return     int	The number of rows affected by last update statement.  For most
  * 				uses there is only one update statement executed, so this number
  * 				will correspond to the number of rows affected by the call to this
  * 				method.  Note that the return value does require that this information
  * 				is returned (supported) by the Propel db driver.
  * @throws     PropelException
