Question

我可以选择具有多个更新触发器的所有表吗？以下代码选择具有多个触发器的所有表，但我只需要具有多个更新触发器的表。此查询还返回具有一个插入触发器和一个更新一个的表，这不是我想要的。

SELECT * FROM sys.triggers
WHERE parent_id IN(SELECT parent_id
FROM sys.triggers
GROUP BY parent_id
HAVING COUNT(*)>1)

Answer 1

您应该能够从sys.trigger_events中告诉它，例如：

SELECT *
  FROM sys.trigger_events AS te
  INNER JOIN sys.triggers AS t
  ON t.[object_id] = te.[object_id]
  WHERE te.[type] IN (1,2,3);

因此要获得具有多个更新触发器的表：

SELECT OBJECT_NAME(parent_id)
  FROM sys.triggers AS t
  INNER JOIN sys.trigger_events AS te
  ON t.[object_id] = te.[object_id]
  WHERE te.type_desc = 'UPDATE'
  GROUP BY OBJECT_NAME(parent_id)
  HAVING COUNT(*) > 1;

Answer 2

不太可靠，但如果您需要快速而肮脏的东西，它应该可以使用。

SELECT * FROM sys.triggers
WHERE parent_id IN
(SELECT parent_id
FROM sys.triggers tt
JOIN sys.syscomments sc on sc.id=tt.object_id
WHERE sc.text LIKE '%AFTER UPDATE%'
GROUP BY parent_id
HAVING COUNT(*)>1)

我可以选择具有多个更新触发器的所有表
