SQL Server2000 触发器修改数据范围错误,高手帮忙,多谢!
我用SQL Server2000的触发器来修改数据,即当修改表Tb_SPPrcPM的数据时,修改和它用外键对应的表Tb_SPPrc的SPPRC_AddDate字段为当前日期。但它有时能正确的修改它对应的信息,有时会把表Tb_SPPrc中所有的数据的SPPRC_AddDate都修改为当前日期。不知道为什么?各位前辈帮忙给看看,多谢了!


-----------------------------------------
触发器代码:
CREATE TRIGGER [Tri_UpdateAddDate_Tb_SPPRCPM]
ON [dbo].[Tb_SPPRCPM]
FOR UPDATE
AS
UPDATE Tb_SPPRC
SET SPPRC_AddDate = GETDATE()
FROM Tb_SPPRCPM a INNER JOIN INSERTED b
ON a.SPPRC_ID = b.SPPRC_ID

修改用的SQL语句(运行这条语句后,所有数据都给修改了):
update tb_spprcpm set spprcpm_delflag='1' where spprcpm_id in('11852','11853','11854')


------解决方案--------------------
[color=#FF0000][/color]
SQL code

CREATE   TRIGGER   [Tri_UpdateAddDate_Tb_SPPRCPM] 
ON   [dbo].[Tb_SPPRCPM] 
FOR   UPDATE 
AS 
UPDATE   Tb_SPPRC 
SET   SPPRC_AddDate   =   GETDATE() 
FROM   [color=#FF0000]Tb_SPPRC[/color]   a   INNER   JOIN   INSERTED   b 
ON   a.SPPRC_ID   =   b.SPPRC_ID

------解决方案--------------------
这样试试

SQL code


CREATE   TRIGGER   [Tri_UpdateAddDate_Tb_SPPRCPM] 
ON   [dbo].[Tb_SPPRCPM] 
AFTER   UPDATE 
AS 
UPDATE   Tb_SPPRC 
SET   SPPRC_AddDate   =   GETDATE() 
WHERE SPPRC_ID IN (SELECT SPPRC_ID FROM INSERTED )
