我对创建一个TRIGGER(在创建表时创建TRIGGER)感兴趣.

在mysql数据库中闲逛,我注意到返回的架构表如下：

从information_schema.TABLES中选择TABLE_NAME,TABLE_SCHEMA；

以下是创建触发器,创建绑定到其他模式的触发器的正确​​方法吗？

DELIMITER //
CREATE TRIGGER `information_schema`.`argus_table_creation`
    AFTER INSERT on `TABLES`
    BEGIN
        --trigger here
        CREATE TRIGGER `argus`.`after_argus_insert` --create trigger bound to DB 'argus', titled 'after_insert'
        AFTER INSERT ON `argus_table_2013_06_27` FOR EACH ROW -- perform the trigger, `after insert`, on the `argus_table_2013_06_27` table, `for each row` that is inserted.
        BEGIN
                INSERT INTO argus.historic_argus_saddrdaddr(saddr, daddr)
                (
                SELECT saddr, daddr
                FROM (SELECT NEW.saddr, NEW.daddr) as derived
                WHERE NOT EXISTS (SELECT saddr, daddr FROM argus.historic_argus_saddrdaddr where historic_argus_saddrdaddr.saddr = derived.saddr and historic_argus_saddrdaddr.daddr = derived.daddr)
                );
        END//
    END//
DELIMITER;

推理：

我使用一个客户端应用程序(rasqlinsert),该应用程序会自动创建与给定命名方案匹配的新表(您可以在其中使用strftime(f)).我需要在这些自动生成的表上创建触发器.这就是为什么我在寻找解决方案.

另一种可能的解决方案

是否可以建议软件开发人员使用类似于CREATE TABLE n LIKE x的命令,但要复制触发器？

附言
与开发人员联系.将在3.0.7.11中进行更改以接受任意SQL与新数据库的创建一起执行.预计代码将在周一发布.

解决方法:

您不能在information_schema数据库中的表上设置触发器.

Usage Notes for the INFORMATION_SCHEMA Database

INFORMATION_SCHEMA is a database within each MySQL instance, the place that stores information about all the other databases that the MySQL server maintains. The INFORMATION_SCHEMA database contains several read-only tables. They are actually views, not base tables, so there are no files associated with them, and you cannot set triggers on them.
