方法1.先删除,再重新建立
if exists (select * from dbo.systypes where name = N'dt_ac_area')
exec sp_droptype N'ssn'
GO
setuser --默认是DBO
GO
EXEC sp_addtypeN'dt_ac_area', N'char (3)', N'not null'
GO
方法2.直接通过数据库全部山删除SRX的 User Defined Data Types:
USE master
go
EXEC sp_configure 'allow updates', '1'
go
RECONFIGURE WITH OVERRIDE
go
use t --database name
go
begin transaction
delete systypes where uid=user_id('srx')
if @@rowcount0
commit transaction
else
rollback transaction
go
use master
go
EXEC sp_configure 'allow updates', '1'
go
RECONFIGURE WITH OVERRIDE
go
还忘记一点，如果你不想删除，你可以用第二种方法直接更新为DBO：
USE master
go
EXEC sp_configure 'allow updates', '1'
go
RECONFIGURE WITH OVERRIDE
go
use t --database name
go
begin transaction
UPDATE systypes SET UID=1 where uid=user_id('srx') --直接更新
if @@rowcount0
commit transaction
else
rollback transaction
go
use master
go
EXEC sp_configure 'allow updates', '1'
go
RECONFIGURE WITH OVERRIDE
go
