Stored Procedures and Caching

  • Big applause. Great article. Nice and tight delievery.

  • Hm, I would call it a bit of article recycling.

    Without compromising the quality, Brian.

  • I would agree, Frank, but I had nothing to do with it, honest!!! Every so often they re-schedule some of the older articles and I guess it was my time. I'm not complaining!

  • Hey, Brian, why should you complain anyway? I like the article, too.

    And I'd rather read a good article twice or more than a not so good article once.

  • Brian,

    Really nice job on the "Stored Procedures and Caching" article.  Looks like a few other folks share my sentiment.  Definitely above the norm of what I've come to expect from "authors", professional or not.  Thanks for the great read.

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.

  • Great article. As a former mainframe DB2 DBA, I was used to having more control over buffering and caching than what SqlServer allows - for better and for worse. and it's good to know a little bit more of the internal behaviour, even if just at a glance, to avoid some future pitfalls. Your article enlightened me.

    Anyway, I think there may be a way around the recompilation problem of procedures with interleaved DML and DDL using nested stored procedures, but I may be wrong... I should try it some time.

  • Brian, i was unable to reproduce the CacheMiss when i executed a SP without specifying owner name. I followed the steps which u mentioned like creating a non-dbo account, creating a dbo owned SP etc., for testing this scenario. But i always got the ExecContextHit event instead of CacheMiss from the second execution.

    Could you please give me some more details on how to reproduce this.

    Thanks for such a great article.
