我再試試去，謝謝。

小無賴

有個(gè)很簡單的方法，把這個(gè)用戶庫備份出來重建之后再load進(jìn)去不就行了嗎。

好，我再試試，非常感謝。
很想知道第二句的3是指的什么，沒看出來，21，我猜是objid=21

或者要等很長時(shí)間？

再幫我看看，629錯(cuò)誤還在繼續(xù)。

if you have much time to confirm what is the situation of your user database,I suggest you do full-database check(command: dbcc checkalloc(db1) & dbcc checkdb(db1)).the time dbcc checkalloc & dbcc checkdb would be in accord with your user data.more data exists,more time is needed.you must not do any transactions in terms of dbcc.
if time is luxury to you,you could check as dbcc tablealloc(3,FULL) & dbcc indexalloc(3,1,FULL). the same check should be did on object 21.if no more error information appear,full-database check is the only option left.
ps:since dbcc tablealloc & dbcc indexalloc have no obvious dbid or dbname parameter,you should make sure check your objects on the database you want.good luck.
