The Cognos Content Store database has a lot of valuable information, however, it is not always so easy to find this information. The following query can be useful for returning REPORT_NAME, PACKAGE and SEARCH-PATH information from the Cognos Content Store database.

Be aware the database structures can be changed with any any patch, fixpack or hotfix to Cognos and this SQL may fail or return wrong results. There is a better method for returning this information by using the Cognos SDK. More info here.

Content Store version:
Cognos 8 running on an Oracle database (also works on Cognos 10)

Thanks to Cognos with Hari for putting this together on a SQL Server Content Store.
