我需要列出SQL Server数据库中的所有触发器表名和表的模式。
我马上就要讲到这个了:
SELECT trigger_name = name, trigger_owner = USER_NAME(uid),table_schema = , table_name = OBJECT_NAME(parent_obj),
isupdate = OBJECTPROPERTY( id, 'ExecIsUpdateTrigger'), isdelete = OBJECTPROPERTY( id, 'ExecIsDeleteTrigger'),
isinsert = OBJECTPROPERTY( id, 'ExecIsInsertTrigger'), isafter = OBJECTPROPERTY( id, 'ExecIsAfterTrigger'),
isinsteadof = OBJECTPROPERTY( id, 'ExecIsInsteadOfTrigger'),
[disabled] = OBJECTPROPERTY(id, 'ExecIsTriggerDisabled')
FROM sysobjects INNER JOIN sysusers ON sysobjects.uid = sysusers.uid
WHERE type = 'TR'
我还需要得到表的模式。
一个困难是文本或描述有换行。我的笨拙的拼凑,使它在更表格的东西,是添加一个HTML文字到SELECT子句,复制并粘贴到记事本,保存与HTML扩展,在浏览器中打开,然后复制并粘贴到一个电子表格。
例子
SELECT obj.NAME AS TBL,trg.name,sm.definition,'<br>'
FROM SYS.OBJECTS obj
LEFT JOIN (SELECT trg1.object_id,trg1.parent_object_id,trg1.name FROM sys.objects trg1 WHERE trg1.type='tr' AND trg1.name like 'update%') trg
ON obj.object_id=trg.parent_object_id
LEFT JOIN (SELECT sm1.object_id,sm1.definition FROM sys.sql_modules sm1 where sm1.definition like '%suser_sname()%') sm ON trg.object_id=sm.object_id
WHERE obj.type='u'
ORDER BY obj.name;
你可能仍然需要使用标签将描述放到一个字段中,但至少它会在一行上,我发现这非常有帮助。
不需要与其他表连接…所有信息都可以从sys.objects中获取。
SELECT name as trigger_name
, object_name(parent_obj) as tableName
, object_schema_name(parent_obj) as schemaName
,OBJECTPROPERTY( id, 'ExecIsUpdateTrigger') AS isupdate
,OBJECTPROPERTY( id, 'ExecIsDeleteTrigger') AS isdelete
,OBJECTPROPERTY( id, 'ExecIsInsertTrigger') AS isinsert
,OBJECTPROPERTY( id, 'ExecIsAfterTrigger') AS isafter
,OBJECTPROPERTY( id, 'ExecIsInsteadOfTrigger') AS isinsteadof
,OBJECTPROPERTY(id, 'ExecIsTriggerDisabled') AS [disabled]
FROM sysobjects s
WHERE s.type = 'TR'
Necromancing。
只是发布,因为到目前为止所有的解决方案都不够完整。

-- https://stackoverflow.com/questions/5340638/difference-between-a-for-and-after-triggers
-- Difference between a FOR and AFTER triggers?
-- CREATE TRIGGER trgTable on dbo.Table FOR INSERT,UPDATE,DELETE
-- Is the same as
-- CREATE TRIGGER trgTable on dbo.Table AFTER INSERT,UPDATE,DELETE
-- An INSTEAD OF trigger is different, and fires before and instead of the insert
-- and can be used on views, in order to insert the appropriate values into the underlying tables.
-- AFTER specifies that the DML trigger is fired only when all operations
-- specified in the triggering SQL statement have executed successfully.
-- All referential cascade actions and constraint checks also must succeed before this trigger fires.
-- AFTER is the default when FOR is the only keyword specified.
