怎么解除SQL Server死锁的问题

Answer 1

查看被锁表：
select request_session_id spid,OBJECT_NAME(resource_associated_entity_id) tableName
from sys.dm_tran_locks where resource_type='OBJECT'

--spid 锁表进程
--tableName 被锁表名

解锁：

declare @spid int
Set @spid = 57 --锁表进程
declare @sql varchar(1000)
set @sql='kill '+cast(@spid as varchar)
exec(@sql)

--查询出死锁的SPID
select 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)

--输出引起死锁的操作
DBCC INPUTBUFFER (@spid)
--查询当前进程数

select count(-1) from sysprocesses
where dbid in (select dbid from sysdatabases where name like '%telcount%');
