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：
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：
:: 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"
