  • Do you think killing the Spid will resolve issue? What about the transaction running behind that?

  • The KILL command does end the transaction being run under the specified SPID. It then has to roll back of course so there may be a delay depending on how big the transaction was.

  • I think KILL command will automatically ROLLBACK the transaction my point is if we use KILL command there will be a data loss.

  • Yes if you use KILL to end a transaction it will be rolled back and any changes made by that transaction will no longer exist. Unfortunately sometimes there is no option. For example if a developer runs an update query but forgets to commit the transaction and then leaves for the night. Then later that evening your batch process won't complete because it's blocked. Your only real option is to kill the developers session and roll back their transaction.

    Another example of using KILL is when you have a runaway query that is taking FAR longer than you intended or can allow.

    KILL is an emergency fix it's not something that should be used on any regular basis.

    I thought you were speaking of killing the developer. That seemed extreme but slightly reasonable. :hehe:

  • I've had days where killing the developer was discussed. Primarily when an Access query was left open over the weekend and blocked the batch cycle that ran at 2am Sat morning. Generally I've found killing the session and a discussion with the developer (after time to cool off) works better and causes the police less concern.

  • We are using the sp_whoisactive stored procedure. You can check it:

    http://sqlmag.com/sql-server/spwhoisactive

    or downloaded it from here:

  • Excellent point. I should have included sp_whoisactive in the article. It is an awesome tool.
