SQLServer死锁的解除方法
SQL Server死锁使我们经常遇到的问题，下面就为您介绍如何查询SQL Server死锁，希望对您学习SQL Server死锁方面能有所帮助。
SQL Server死锁的查询方法：
-
exec master.dbo.p_lockinfo 0,0 ---显示死锁的进程,不显示正常的进程
-
-
exec master.dbo.p_lockinfo 1,0 ---杀死死锁的进程,不显示正常的进程
SQL Server死锁的解除方法：
-
Create proc p_lockinfo
-
@kill_lock_spid bit=1, --是否杀掉死锁的进程,1 杀掉, 0 仅显示
-
@show_spid_if_nolock bit=1 --如果没有死锁的进程,是否显示正常进程信息,1 显示,0 不显示
-
