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。
上面的代码是错误的,如下所示:
SELECT
sysobjects.name AS trigger_name
--,USER_NAME(sysobjects.uid) AS trigger_owner
--,s.name AS table_schema
--,OBJECT_NAME(parent_obj) AS table_name
--,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
/*
INNER JOIN sysusers
ON sysobjects.uid = sysusers.uid
*/
INNER JOIN sys.tables t
ON sysobjects.parent_obj = t.object_id
INNER JOIN sys.schemas s
ON t.schema_id = s.schema_id
WHERE sysobjects.type = 'TR'
EXCEPT
SELECT OBJECT_NAME(parent_id) as Table_Name FROM sys.triggers
上面的代码是错误的,如下所示:
SELECT
sysobjects.name AS trigger_name
--,USER_NAME(sysobjects.uid) AS trigger_owner
--,s.name AS table_schema
--,OBJECT_NAME(parent_obj) AS table_name
--,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
/*
INNER JOIN sysusers
ON sysobjects.uid = sysusers.uid
*/
INNER JOIN sys.tables t
ON sysobjects.parent_obj = t.object_id
INNER JOIN sys.schemas s
ON t.schema_id = s.schema_id
WHERE sysobjects.type = 'TR'
EXCEPT
SELECT OBJECT_NAME(parent_id) as Table_Name FROM sys.triggers
这是我使用的(通常包装在模型中):
Select
[Parent] = Left((Case When Tr.Parent_Class = 0 Then '(Database)' Else Object_Name(Tr.Parent_ID) End), 32),
[Schema] = Left(Coalesce(Object_Schema_Name(Tr.Object_ID), '(None)'), 16),
[Trigger name] = Left(Tr.Name, 32),
[Type] = Left(Tr.Type_Desc, 3), -- SQL or CLR
[MS?] = (Case When Tr.Is_MS_Shipped = 1 Then 'X' Else ' ' End),
[On?] = (Case When Tr.Is_Disabled = 0 Then 'X' Else ' ' End),
[Repl?] = (Case When Tr.Is_Not_For_Replication = 0 Then 'X' Else ' ' End),
[Event] = Left((Case When Tr.Parent_Class = 0
Then (Select Top 1 Left(Te.Event_Group_Type_Desc, 40)
From Sys.Trigger_Events As Te
Where Te.Object_ID = Tr.Object_ID)
Else ((Case When Tr.Is_Instead_Of_Trigger = 1 Then 'Instead Of ' Else 'After ' End)) +
SubString(Cast((Select [text()] = ', ' + Left(Te.Type_Desc, 1) + Lower(SubString(Te.Type_Desc, 2, 32)) +
(Case When Te.Is_First = 1 Then ' (First)' When Te.Is_Last = 1 Then ' (Last)' Else '' End)
From Sys.Trigger_Events As Te
Where Te.Object_ID = Tr.Object_ID
Order By Te.[Type]
For Xml Path ('')) As Character Varying), 3, 60) End), 60)
-- If you like:
-- , [Get text with] = 'Select Object_Definition(' + Cast(Tr.Object_ID As Character Varying) + ')'
From
Sys.Triggers As Tr
Order By
Tr.Parent_Class, -- database triggers first
Parent -- alphabetically by parent
正如你所看到的,这是一个McGyver,但我认为这是值得的:
Parent Schema Trigger name Type MS? On? Repl? Event
-------------------------------- ---------------- -------------------------------- ---- ---- ---- ----- -----------------------------------------
(Database) (None) ddlDatabaseTriggerLog SQL X DDL_DATABASE_LEVEL_EVENTS
Employee HumanResources dEmployee SQL X Instead Of Delete
Person Person iuPerson SQL X After Insert, Update
PurchaseOrderDetail Purchasing iPurchaseOrderDetail SQL X X After Insert
PurchaseOrderDetail Purchasing uPurchaseOrderDetail SQL X X After Update
PurchaseOrderHeader Purchasing uPurchaseOrderHeader SQL X X After Update
SalesOrderDetail Sales iduSalesOrderDetail SQL X X After Insert, Update, Delete
SalesOrderHeader Sales uSalesOrderHeader SQL X After Update (First)
Vendor Purchasing dVendor SQL X Instead Of Delete
WorkOrder Production iWorkOrder SQL X X After Insert
WorkOrder Production uWorkOrder SQL X X After Update
