今天工作需要，想要实现将仅对状态更新的表进行历史记录显示，于是考虑在原表中建立触发器，将更新的内容同时写入另一张表
于是进行测试
| -- 建立测试表 CREATE TABLE `triggletest_triggle` (`id` INT(11) NOT NULL, | |
| `name` VARCHAR(5) NULL DEFAULT NULL, | |
| PRIMARY KEY (`id`) | |
| ) | |
| COLLATE='latin1_swedish_ci' | |
| ENGINE=InnoDB |
| -- 建立目标表 | |
| CREATE TABLE `triggletest` (`seq` INT(11) NOT NULL, | |
| `id` INT(11) NOT NULL, | |
| `name` VARCHAR(5) NULL DEFAULT NULL, | |
| PRIMARY KEY (`seq`), | |
| INDEX `id` (`id`) | |
| ) | |
| COLLATE='latin1_swedish_ci' | |
| ENGINE=InnoDB; |
| --- 写入测试数据 | |
| INSERT INTO `triggletest_triggle` VALUES(1,'A'); |
| -- 建立触发器 | |
| DROP TRIGGER if EXISTS test1 | |
| CREATE TRIGGER test1 | |
| AFTER UPDATE ON triggletest_triggle | |
| FOR EACH ROW | |
| BEGIN | |
| INSERT INTO triggletest(id) values (new.id); | |
| END |
执行触发器语句，报错，报错内容如下：
/* SQL 错误（1064）：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 ‘CREATE TRIGGER test1
AFTER UPDATE ON triggletest_triggle
FOR EACH ROW
BEGIN ‘ at line 2 */
问题待查
