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。
SELECT
ServerName = @@servername,
DatabaseName = db_name(),
SchemaName = isnull( s.name, '' ),
TableName = isnull( o.name, 'DDL Trigger' ),
TriggerName = t.name,
Defininion = object_definition( t.object_id )
FROM sys.triggers t
LEFT JOIN sys.all_objects o
ON t.parent_id = o.object_id
LEFT JOIN sys.schemas s
ON s.schema_id = o.schema_id
ORDER BY
SchemaName,
TableName,
TriggerName
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.
