Get report name, package, and path from Cognos content store database

Query the Cognos Content Store Database

While working with a client on a Cognos upgrade effort, I was asked to provide a list of each report by the package it sourced. Since I am a database fanatic I prefer to get this information directly from the Cognos content store. Ultimately, I was able to provide a list with each Report name, package and path for each report by using the query provided below.

The Cognos content store has a lot of valuable information. Unfortunately, it is not always so easy to find this information. Have you ever been asked where a specific report can be found in Cognos? Or better yet, have you had to find all the existing reports that use a certain package? Below you will find a query useful for finding Report Name, Package and Path information from the Cognos content store database.

Let us know in the comments if you have done something similar or encountered any challenges around using the content store as a data source.

This example works with Cognos 10 running on an Oracle database. In addition, it will also work on the Cognos 8 content store.

Be aware that future patches or hotfixes from the vendor may cause this SQL to fail or return incorrect results. There is a better method for returning this information by using the Cognos SDK. More info here.

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