List All SSIS Packages Deployed On Your Integration Server

One way of checking wich SSIS packages you've deployed on your integration server and wich version build numbers they have is by running a TSQL query against the MSDB database on the server where your integration services  is running.

I found the following blogpost with a very usefull TSQL script:

NOTE: the query was written for SQL Server 2008. For SQL Server 2005: sysssispackagefolders => sysdtspackagefolders90 and sysssispackages => sysdtspackages90.
