SQL Profiler query cleaner

I just open-sourced a tool that I wrote that I've been using internally at Zimbra (previously Telligent) for almost a year. It's an ugly little tool that I wrote out of frustration, but I've gotten so much use and time savings out of it that I thought I would share it. It's called SQL Profiler Query Cleaner.

SQL Profiler is a great tool to show you exactly what SQL is being executed, along with the parameters. This is especially useful when debugging, because sometimes you aren't sure what SQL is being executed. However, often times I will find myself having to pull that SQL+parameters out of SQL Profiler and paste it into SQL Server Studio in order to analyze, tweak, debug, etc. However, notce the output of SQL Profiler (bottom part of the screenshot):

The SQL string is there, but there are escaped characters. The parameters and arguments are there, but they're first declared, then assigned, "doubling" the syntax. It executes fine in SQL Studio, but if there's a syntax error, you can't really pinpoint exactly where in the query the error is, because you have to unescape the strings, manipulate the parameters (in two spots), and it's just time-consuming if you're doing this a lot (which I was).

So, fire up Sql Profiler Query Cleaner, paste the SQL Profiler output into the top text box, click the "Clean" button, and the bottom text box will have a more SQL Studio friendly query. I pasted the query from the above screenshot, and this is the result:

Please let me know if you find this useful. My guess is that if you use SQL Profiler a lot, this tool will save you some time.
