触发器在插入时尝试插入另一个数据库时抛出错误

Question

我试图从本地主机下同一服务器上的 'fold' 数据库插入 'latestdb'，抛出此错误：

错误 SQL查询：

CREATE trigger after_insert_db1_t1 AFTER INSERT ON  `fold`.pr_users
FOR each
ROW BEGIN INSERT INTO  `latestdb`.pr_users(

username,
userpass,
email
)
VALUES (
NEW.username, NEW.userpass, NEW.email
);

MySQL 说：文档

1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use

near '' at line 1

两个表具有相同的名称，具有这些字段 -

id、username、userpass、email、departmentid、userroleid、managerid、userlevel、branchid、is_global、registrationtime、timemodified、modifierid、status、deleted、temppass , temppassvalidtill, lastlogin, lastrefresh, lastloginip, if_online, pfield, company

但我只想复制 3 个字段 - 用户名、用户密码、电子邮件

Answer 1

删除 BEGIN 和 END; 似乎消除了此处的语法错误问题。

CREATE TRIGGER after_insert_db1_t1 
    AFTER INSERT ON `fold`.pr_users 
FOR EACH ROW
    INSERT INTO `latestdb`.pr_users(
       username, userpass, email
    )
    VALUES (
       NEW.username, NEW.userpass, NEW.email
    );
