我需要在两个数据库之间有一个触发器，当一行插入到db1中的tbl1时，这一行插入到db2中的tbl2中。在mysql中触发两个数据库之间的mysql
CREATE TRIGGER `update_users` AFTER INSERT ON `db1`.`tbl1`
FOR EACH ROW INSERT INTO `db2`.`tbl2` (id,email,password)
VALUES
(???)
在VALUES中写什么？
参见例如：
mysql> CREATE DATABASE `db1`;
Query OK, 1 row affected (0.00 sec)
mysql> CREATE DATABASE `db2`;
Query OK, 1 row affected (0.00 sec)
mysql> USE `db1`;
Database changed
mysql> CREATE TABLE `tbl1` (
-> `id` INT UNSIGNED,
-> `email` VARCHAR(255),
-> `password` VARCHAR(255)
->);
Query OK, 0 rows affected (0.01 sec)
mysql> DELIMITER //
mysql> CREATE TRIGGER `update_users` AFTER INSERT ON `tbl1`
-> FOR EACH ROW
-> BEGIN
-> INSERT INTO `db2`.`tbl2` (`id`, `email`, `password`)
-> VALUES
-> (NEW.`id`, NEW.`email`, NEW.`password`);
-> END//
Query OK, 0 rows affected (0.00 sec)
mysql> DELIMITER ;
mysql> USE `db2`;
Database changed
mysql> CREATE TABLE `tbl2` (
-> `id` INT UNSIGNED,
-> `email` VARCHAR(255),
-> `password` VARCHAR(255)
->);
Query OK, 0 rows affected (0.00 sec)
mysql> USE `db1`;
Database changed
mysql> INSERT INTO `tbl1` VALUES (1, '[email protected]', 'secret');
Query OK, 1 row affected (0.00 sec)
mysql> SELECT `id`, `email`, `password` FROM `tbl1`;
+------+-----------------+----------+
| id | email | password |
+------+-----------------+----------+
| 1 | [email protected] | secret |
+------+-----------------+----------+
1 row in set (0.00 sec)
mysql> SELECT `id`, `email`, `password` FROM `db2`.`tbl2`;
+------+-----------------+----------+
| id | email | password |
+------+-----------------+----------+
| 1 | [email protected] | secret |
+------+-----------------+----------+
1 row in set (0.00 sec)
变化''???通过：'NEW.id，NEW.email，NEW.password'，理解的是，列名这两个数据库的两个表中是相同的。 – wchiquito
谢谢@wchiquito –
@wchiquito这是在本地工作，但用户root没有密码，但在服务器用户和密码都设置为数据库和这个触发器不工作！帮帮我！ –
