When I run the metadate wizzard to connect to MS SQL server 2005 Express I just see the tables as query subject information, but no columns.
Isn't it possible to connect Cognos 8.3 with Microsoft Sql server 2005 Express ??
Problem solved :D :D
At first I selected signons and password with my MS SQL password and username. When selecting Cognos Credentials I see column names too.
