SSMS ToolsPack – Powershell Turboboost

I have been using the rather brilliant SSMSToolsPack from Mladen Prajdić recently and love the query execution history feature.

I like to keep my history around for a while – I do a lot of work that then has to be repeated later – and this tool lets me not worry about forgetting to save that important query I ran for someone weeks ago.

I ran in to a little problem though.  All those query executions have to be stored somewhere, this is done by setting a folder to store the query text. 

SSMSToolsPack stores the query text in txt files, these can get out of control if you run enough queries.  They are then stored per day in a folder; so for today the queries would be stored in the folder “2010-12-03”.

If you want to search through the history and have a great number of files and folders, the search can get very slow (I suspect this has to do with the directory and file traversal).  I am lucky to have a small SSD on my main machine, I store source code and the execution history files/folders on there.  This speeds things up, but it seems that even then the search is sluggish (takes about 30 seconds to index on my machine).

I took a quick look at these files and saw that they were basically all the same content wise.  I tried just combining the files to see if that could improve the performance of searching and lo-and-behold search was blazingly fast!

Being lazy, I whipped up a script in Powershell to make this easier/semi-automatic and here it is:

clear host
$path = "" #Set path here!
foreach ($folder in Get-ChildItem $path)
  if ($folder.PSIsContainer -eq "False")
      foreach ($file in Get-ChildItem $folder.FullName)
         $target = $path+$folder.Name+"\output.txt" #set output file
         if ($file.Name -ne "output.txt")
          { #concatenate content of all files except output
            cat $file.FullName > $target 
            #del $file.FullName #delete the file after processing

It is nothing special, but maybe if you use SSMSToolsPack and have experienced a similar slowdown, you can use this to help.
