Failed to retrieve data from the database

Hi,

I'm currently getting this error when I'm trying to view the report by using the SDK in a .NET application:

"Failed to retrieve data from the database.

Details: [Database Vendor Code: 6550]....."

I can preview the report in Crystal Reports 2008 without any issues. The data comes back fine. However, whenever I'm using the SDK to view the report through the CrystalReportViewer I would get that message. Has someone experienced the same error? I'm accessing data from an Oracle database.

thanks,
