在更新后进行批量更新时触发mysql

Question

table DI_WF_NAMESPACE having columns
 `ID` int(11) NOT NULL AUTO_INCREMENT,
  `NAMESPACE_KEY` varchar(100) DEFAULT NULL,
  `NAMESPACE_VALUE` varchar(250) DEFAULT NULL,
  `OVERRIDABLE_FLAG` bit(1) DEFAULT NULL,
  `FILE_PATTERN_ID` int(11) DEFAULT NULL

我正在创建触发器

CREATE TRIGGER TGR_WF_NAMESPACE AFTER UPDATE ON DI_WF_NAMESPACE
         FOR EACH ROW
             DELETE FROM DI_WF_NAMESPACE WHERE FILE_PATTERN_ID IS NULL

更新表时，列FILE_PATTERN_ID的多行变为NULL，我想删除NULL列中FILE_PATTERN_ID的所有行。

这样做时我收到错误
