sql - How to get list of tables without any active triggers?

Question

I have database in SQL Server 2008 with triggers on almost every table. I need to review tables without active triggers.
How to get list of all tables without any active triggers (tables without any triggers or those tables where all triggers are disabled)?

Answer 1

sys.tables您可以在和之间进行反半连接sys.triggers。

例如与NOT IN

SELECT *
FROM   sys.tables
WHERE  object_id NOT IN (SELECT parent_id
                         FROM   sys.triggers
                         WHERE  is_disabled = 0)

或者NOT EXISTS

SELECT *
FROM   sys.tables t
WHERE  NOT EXISTS (SELECT *
                   FROM   sys.triggers tr
                   WHERE  is_disabled = 0
                          AND tr.parent_id = t.object_id) 

sys.tables.object_id两者或 都不能sys.triggers.parent_id为空，在这种情况下，两者都给出相同的语义和计划。
