[prcgolf]

现在可以了，多谢J老师！！

可得多向大虾们多学学！

[CCEO]

收藏，

J9988:
看你的另一个贴（触发器问题），测试过对2000没问题，6.5肯定不行。但是还时不敢保证对2000正确（微软未公开）。

[qdubit]

谢谢楼主了！俺要收藏！

[cadinfo]

不错我测试过了，不过有点疑问，请路过的朋友指点一二，必谢
------------------------------------------------------------
……
1.
set @sql1='ALTER TRIGGER '+@objectname+' ON '+OBJECT_NAME(@parentid)+' WITH ENCRYPTION FOR INSERT AS PRINT 1 '
~~~~~~~~~~这里的 as print 1 什么意思，for insert是不是不管具体是delete，update或者insert都没有关系
……
2.我得到了SQLExplore的解密过程，它采用：
SET @trigtype=(SELECT CASE WHEN dbo.sysobjects.deltrig > 0 THEN 'DELETE'
WHEN dbo.sysobjects.instrig > 0 THEN 'INSERT'
WHEN dbo.sysobjects.updtrig > 0 THEN 'UPDATE' END
FROM dbo.sysobjects INNER JOIN dbo.sysobjects sysobjects_1 ON dbo.sysobjects.parent_obj = sysobjects_1.id WHERE (dbo.sysobjects.type = 'TR') AND (dbo.sysobjects.name = @ObjectName))
来得到触发器类型，可是实际上并非如此，我的insert类型的触发器也是在deltrig字段有反应，那结果还是正确的？

3.本段解密脚本的前面部分Alter @objectname做什么用的啊？

[j9988]

1.先修改原过程，然后比较用。print 1没意义，只不过让触发器完整。
2.SQLExplore这样做太麻烦了。画蛇添足，且它那种判断触发器方法也不行。我上面已经说过了。
3.同1 ，比较用。

[passionke]

呵呵,省事了

[j9988]

本贴200分归CCEO，详见：
http://expert.csdn.net/Expert/TopicView1.asp?id=2377806

[cadinfo]

要知道触发器是否enable，必须根据不同类型进行判断！

SELECT NAME,CASE WHEN STATUS & 0X2000<>0 THEN 'Y' ELSE NULL END AS [INSTEAD OF],
CASE WHEN STATUS & 0X100<>0 THEN 'Y' ELSE NULL END AS [DELETE],
CASE WHEN STATUS & 0X200<>0 THEN 'Y' ELSE NULL END AS [UPDATE],
CASE WHEN STATUS & 0X400<>0 THEN 'Y' ELSE NULL END AS [INSERT],
CASE WHEN STATUS & 0X900<>0X900 AND STATUS & 0XA00<>0XA00 AND STATUS & 0XC00<>0XC00 THEN 'Y' ELSE 'N' END AS [ENABLED]
FROM SYSOBJECTS
WHERE TYPE='TR'
