[SqlServer] 处理死锁

1. 查看所有当前被锁的表

select distinct request_session_id  spid,b.namefrom sys.dm_tran_locks a join sysobjects b on a.resource_associated_entity_id=b.idwhere a.resource_type='OBJECT' and b.xtype='u'

2. 查看导致某个死锁的操作

DBCC INPUTBUFFER (88); -- spid=88

3. 杀死指定死锁进程

exec('kill 88'); -- spid=88

4. 杀死所有死锁进程
