SqlServer强制断开数据库已有连接的方法

在执行建库脚本时,往往会先将原有的数据库drop掉,由于SqlServer检测到有数据连接时禁止执行drop database操作,所以建库脚本经常执行失败,为此我们需要一种能强制断开数据库已有连接的方法,可以过如下t-sql实现:
代码如下:
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
我们可以把这条sql写到建库的批处理脚本里,放在脚本的开始:
代码如下:
:: 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"
