Aborting/ Killing A Long Running Stored Procedure

This blog acquaints you with aborting/ killing a long running stored procedure.

Take a scenario, where you wrote a SQL stored procedure in MS SQL Server DBMS and made some mistake of not handling a scenario, where SP keeps running for an infinite time or takes hours to finish the required task.

In this case, basically you are stuck with SQL Server, which is consuming a huge amount of memory and blocking the Server for further use.

There can be 2 ways to handle this.

1. Shutdown/Restart MS SQL Server
2. Abort/ kill/ stop SP

Option 1 is not a practical way to handle it in some environments where other people are using SQL Server.

The way given below tells about using a second option.

This has 2 steps.

Step 1

Identify the Thread/ process which, is executing SP

Step 2

Kill the process

declare @spid int

select session_id,*
from sys.dm_exec_requests handle
outer apply sys.fn_get_sql(handle.sql_handle) spname
where spname.text like '%USP_LongRunningSP%'
print @spid

exec ('kill ' + @spid)

USP_LongRunningSP is the procedure name or the part of the procedure name, if you do not remember the entire name.
