Question

我正在尝试创建一个监视表上更改的触发器，然后将这些更改插入到另一个表中，如下所示

CREATE TRIGGER userChangePasswd
BEFORE UPDATE ON originalTable
FOR EACH ROW
BEGIN
INSERT INTO logs (email,clear,name ) SELECT email,clear,name FROM  originalTable
END

mysql一直显示以下错误

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'INSERT INTO logs (email,clear,name ) SELECT email,clear,name FROM ' originalTable at line 5

以下语句使用where子句标准

INSERT INTO logs (email,clear,name ) SELECT email,clear,name FROM  originalTable

触发器中的insert语句有什么问题

Answer 1

CREATE TRIGGER `orgTbl_before_upd_tr` BEFORE UPDATE ON `orgTbl`
FOR EACH ROW
BEGIN
  INSERT INTO newTbl (field1, field2) VALUES (old.field1, old.field2);
END;

MySQL触发器：ERROR 1064（42000）：您的SQL语法有错误
