在執(zhí)行建庫(kù)腳本時(shí)，往往會(huì)先將原有的數(shù)據(jù)庫(kù)drop掉，由于SqlServer檢測(cè)到有數(shù)據(jù)連接時(shí)禁止執(zhí)行drop database操作，所以建庫(kù)腳本經(jīng)常執(zhí)行失敗，為此我們需要一種能強(qiáng)制斷開數(shù)據(jù)庫(kù)已有連接的方法，可以過如下t-sql實(shí)現(xiàn)： 

復(fù)制代碼代碼如下:

declare @i int declare cur cursor for select spid from sysprocesses where db_name(dbid)= 'Your_Database_Name' open cur fetch next from cur into @i while @@fetch_status=0 begin exec('kill '+@i) fetch next from cur into @i end close cur deallocate cur 

我們可以把這條sql寫到建庫(kù)的批處理腳本里，放在腳本的開始： 

復(fù)制代碼代碼如下:

:: Disconnect existing Fortune database connections 
osql -S"%1" -U"%2" -P"%3" -Q"declare @i int declare cur cursor for select spid from sysprocesses where db_name(dbid)= ' Your_Database_Name ' open cur fetch next from cur into @i while @@fetch_status=0 begin exec('kill '+@i) fetch next from cur into @i end close cur deallocate cur"
