mysql触发器显示错误

Question

我想在我的一个表中发生插入时转换字段。

检查和 ged 的​​ => 检查和 geds。

    DELIMITER $$
    CREATE
    TRIGGER `perma_limk_insertion` AFTER INSERT
    ON `tbl_magazine`
    FOR EACH ROW BEGIN

    DECLARE magazine_name VARCHAR(100); 
    @magazine_name := REPLACE(FieldName,'&','and');
    @magazine_name := REPLACE(FieldName,"'",'');
    UPDATE tbl_magazine SET perma_link = magazine_name WHERE MAGAZINE_ID = NEW.MAGAZINE_ID;
   END$$
   DELIMITER ;

这是我的触发器。但我收到一个错误

 #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 '@magazine_name := REPLACE(FieldName,'&','and'); @magazine_name := REPLA' at line 7

如果有人知道这件事。请帮助我

提前致谢

Answer 1

您需要将变量 FieldName 更改为要对其运行函数 REPLACE 的列的名称(在本例中为列名称 perma_link)。

您的代码将是:

...
@magazine_name := REPLACE(perma_link,'&','and');
@magazine_name := REPLACE(perma_link,"'",'');
UPDATE tbl_magazine SET perma_link = magazine_name WHERE MAGAZINE_ID = NEW.MAGAZINE_ID;
...
