    POPS
    DBCC DROPCLEANBUFFERS
    Osolage
    by Osolage  6-7-2007    1
     I saw one of my colleagues using this procedure. I haven't used it myself, but I think I'm about to start experimenting with it. I think the part about executing a CHECKPOINT first makes sense.

    Indexes have their disadvantages
    Osolage
    by Osolage  6-7-2007   
     I've seen a lot of people talk about the consumption of disk space with respect to indexes, but I don't remember seeing mention of how it could consume memory space. I believe that makes sense. And seeing how I'm fighting with memory right now, it makes me think twice about slapping yet another index on my tables.

     I'm not sure I usually have to worry about this one, but we'll see.

     Yep, this is definitely something I should take a look at then.

    Design queries using SHOWPLAN turned on
    Osolage
    by Osolage  4-10-2007   
     Yeah, this makes a lot of sense to do. I hadn't thought of it like that before. I've found myself turning Execution Plan on when working on complex procedures, but I don't make it part of my regular habit. I think this practice will be good for me to start doing.

    Table Spool should alert you to a potential problem
    Osolage
    by Osolage  3-26-2007   
     I was looking at a query plan today and saw a Table Spool icon. I had never seen one of those before. I thought that it might not be so great. I found this little bit of text on spooling data to work tables and thought it was interesting.
