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 masterdbop_lockinfo 显示死锁的进程不显示正常的进程
exec masterdbop_lockinfo 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= 是否杀掉死锁的进程 杀掉 仅显示
@show_spid_if_nolock bit= 如果没有死锁的进程是否显示正常进程信息 显示 不显示
