SQL 错误:查询已超时 或者 查询其他表正常,但指定某个表一直显示"正在执行中..."
解决方法:先通过 查询 阻塞/死锁 的进程模块,找到进程ID,然后杀死 阻塞/死锁 的进程
1、查询
方法1:
select * from sys.sysprocesses where blocked<>0
方法2:
use master
go
select spid, blocked, loginame, last_batch, status, cmd, hostname, program_name from sysprocesses
where spid in ( select blocked from sysprocesses where blocked <> 0 ) or (blocked <>0)
方法3:
declare
@spid int,
@bl int
DECLARE s_cur CURSOR FOR
select 0 ,blocked from (select * from sys.sysprocesses where blocked>0 ) a
where not exists(select * from (select * from sys.sysprocesses where blocked>0 ) b where a.blocked=spid)
union
select spid,blocked from sys.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
2、解决( kill spid(进程号) )
例如:
kill 56
