I triggered a very inefficient query against a Azure SQL Server instance that has been running now for hours. I have tried looking at the active spid and trying to kill the process that started it but couldn’t find it.

On the performance reports I get a query id. Maybe there is a way to trace the queryid back to a spid and terminate it?

I also can't restart the Azure SQL Server database to terminate it. I tried scaling up and down but no luck.

I can find it by querying:

SELECT * FROM sys.query_store_plan where query_id = 1111

What can I do?

  • Well, what's in sys.dm_exec_requests? – Aaron Bertrand Dec 11 '18 at 14:16
  • Is it still running? If so, run sp_who2 ‘active’ which will give you the SPID, which you can then Kill(spid). if you’re not sure which it is then run it through DBCCInputBuffer(spid) – pix1985 Dec 11 '18 at 15:25
  • Nothing much really. I can't also see nothing strange by doing sp_who2. All are in sleeping or background mode and the only "running" is my own process to do the query (tried KILL on it and couldn't). The way I know it is running is by doing an "Overall Resource Consumption" query where the query is shown as still running (over a day already). – despuestambien Dec 11 '18 at 15:41
  • Might it be that the query id is not related to a running query in the background but rather the same query executed over and over by the application? My concern was that I had triggered a very expensive (with 3 nested SELECTs) on a table with 2Million records that was running in the background, but maybe this is not the case? – despuestambien Dec 11 '18 at 16:09
  • Can you show a screen shot that suggests the query is still running? If it's not in sys.dm_exec_requests and it doesn't show up in sp_who2 then I think your performance report is either wrong or being misinterpreted. – Aaron Bertrand Dec 11 '18 at 19:42
