mysql - 触发器中的语法不正确

Question

我有两个表，称为帐户和交易。帐户插入数据时，我需要自动将数据插入事务。我在 MySQL 中创建了这个触发器。它给出错误 1064（语法错误）。问题是什么？

CREATE TRIGGER upTransaction AFTER INSERT ON account FOR EACH ROW
BEGIN
  INSERT INTO transaction VALUES (2,account.openDate,CURTIME(),
    account.deposit,account.accNo,
    "Teller","Cash","Deposit");
END

Answer 1

MySQL 与 BEGIN END 块内的分号混淆，因此您必须使用 DELIMITER 临时强制 MySQL 使用不同的分隔符。
文档：http ://dev.mysql.com/doc/refman/5.5/en/create-trigger.html

DELIMITER //
CREATE TRIGGER upTransaction AFTER INSERT ON account FOR EACH ROW
BEGIN
  INSERT INTO transaction VALUES (2,account.openDate,CURTIME(),account.deposit,account.accNo,"Teller","Cash","Deposit");
END//
DELIMITER ;

您可能需要更换：

      INSERT INTO transaction VALUES (2,account.openDate,CURTIME(),account.deposit,account.accNo,"Teller","Cash","Deposit");

和：

      INSERT INTO transaction VALUES (2,NEW.openDate,CURTIME(),NEW.deposit,NEW.accNo,"Teller","Cash","Deposit");

Answer 2

这是你原来的触发器

CREATE TRIGGER upTransaction AFTER INSERT ON account FOR EACH ROW
BEGIN
  INSERT INTO transaction VALUES (2,account.openDate,CURTIME(),
    account.deposit,account.accNo,
    "Teller","Cash","Deposit");
END

替换account.为NEW.（可选：替换"为'）

DELIMITER $$
CREATE TRIGGER upTransaction AFTER INSERT ON account FOR EACH ROW
BEGIN
  INSERT INTO transaction VALUES (2,NEW.openDate,CURTIME(),
    NEW.deposit,NEW.accNo,
    'Teller','Cash','Deposit');
END $$
DELIMITER ;

Answer 3

CREATE
TRIGGER `event_name` AFTER INSERT
ON `database`.`table`
FOR EACH ROW BEGIN
    -- trigger body
    -- this code is applied to every
    -- inserted/updated/deleted row
END;

好像您在“帐户”之后缺少表名。（编辑：或帐户之前的数据库名称，我不确定帐户属于什么）
