深入探讨如何解决数据库中的死锁问题

Answer 1

具体的解决方法如下：1.再死锁发生时,我们可以通过下面的语法,查询到引起死锁的操作： use master go declare @spid int,@bl int DECLARE s_cur CURSOR FOR select 0 ,blocked from (select * from sysprocesses where blocked>0 ) a where not exists(select * from (select * from sysprocesses where blocked>0 ) b where a.blocked=spid) union select spid,blocked from sysprocesses where blocked>0 OPEN s_cur FETCH NEXT FROM s_cur INTO @spid,@bl WHILE @@FETCH_STATUS = 0 begin if @spid =0 select '引起数据库死锁的是: '+ CAST(@bl AS VARCHAR(10)) + '进程号,其执行的SQL语法如下' else select '进程号SPID：'+ CAST(@spid AS VARCHAR(10))+ '被' + '进程号SPID：'+ CAST(@bl AS VARCHAR(10)) +'阻塞,其当前进程执行的SQL语法如下' DBCC INPUTBUFFER (@bl ) FETCH NEXT FROM s_cur INTO @spid,@bl end CLOSE s_cur DEALLOCATE s_cur exec sp_who2 2.然后查找程序/数据库,此t_sql语法具体在什么地方使用。3.分析已经找到的,解决问题。
