Sql DDL触发一切

我用著名的DDL触发器触发数据库中发生的一切

在本例中，它被设置为

FOR CREATE_PROCEDURE, ALTER_PROCEDURE, DROP_PROCEDURE

但我假装要为每个DDL更改进行扩展，所以我搜索：

超过200项活动

我们可以用类似的东西吗？

CREATE TRIGGER DDLTrigger_Sample
    ON DATABASE
    FOR ABSOLUTELY_EVERYTHING
AS
BEGIN

---

简短的回答是的。DDL触发器事件是分层的。您可以在

sys.trigger\u event\u types

中看到这些关系。例如，让我们看看

DROP\u PROCEDURE

所在的层次结构，我们可以使用以下查询：

WITH e AS (
    SELECT tet.type ,
           tet.type_name ,
           tet.parent_type, 1 AS level
    FROM sys.trigger_event_types AS tet
    WHERE tet.type_name = 'DROP_PROCEDURE'

    UNION ALL

    SELECT parent.type ,
           parent.type_name ,
           parent.parent_type, child.level + 1 AS level
    FROM e AS child
    JOIN sys.trigger_event_types AS parent
        ON child.parent_type = parent.type
)

SELECT *
FROM e
ORDER BY level DESC;

从中，我可以看到（在我的服务器上），

DROP\u PROCEDURE

属于

DDL\u PROCEDURE\u EVENTS

，

DDL\u DATABASE\u LEVEL\u EVENTS

，以及

DDL\u EVENTS

（按粒度递减顺序）。假设您选择了

DDL\u DATABASE\u LEVEL\u EVENTS

，您可以计算出下面将要讨论的所有内容

WITH e AS (
    SELECT tet.type ,
           tet.type_name ,
           tet.parent_type, 1 AS level
    FROM sys.trigger_event_types AS tet
    WHERE tet.type_name = 'DDL_DATABASE_LEVEL_EVENTS'

    UNION ALL

    SELECT child.type ,
           child.type_name ,
           child.parent_type ,
           parent.level + 1 AS level
    FROM e AS parent
    JOIN sys.trigger_event_types AS child
        ON child.parent_type = parent.type
)

SELECT *
FROM e
ORDER BY level
