Label:The use of SQL Server as a database application system, will not be able to sometimes create a deadlock, after the deadlock, the maintenance personnel or developers will mostly only through the sp_who to find the deadlock process, and then killed with Sp_kill. With Sp_who_lock This stored procedure, it is easy to

Label:Many times, deadlocks are requested by two or more sessions to hold the other session of the lock while holding other session, but there are some special deadlock only by a single session lock triggered, today saw a related article, transported to share with you! The code that caused the deadlock: Execution Environment SQL SERVER 2012 (11.0.5058) BEGIN TRAN

Using SQL Server as a database application system, can not avoid the sometimes deadlock, deadlock, maintenance personnel or developers will only through the sp_who to find the deadlock process, and then kill with Sp_kill. Using Sp_who_lock, this stored procedure makes it easy to know which process is deadlocked and whe

. status nchar (+) Process ID status. The possible values are: dormant= SQL Server is resetting the session. The running= The session is running one or more batches. When multiple Active Result sets (MARS) is enabled, a session can run multiple batches. For more information, seeusing multiple Active Result sets (MARS). Background= The session is running a background task, such as

sp_lock, it is possible to get different results because new locks have taken place, and some of the old locks have been lifted. If you find that sp_lock returns a large number of results with the same SPID, it is likely that the process is undergoing large processing, and these locks may begin to prevent new transactions from occurring.When you find that a SPID acquires a large number of database locks, this will help determine what stored procedures or statements are running. To achieve this,
