Dear all,

I have an ODBC connection with a Universe database. When trying to get some data with a SELECT statement, I get the following error:

Unexpected error: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
Details:
Microsoft.Mashup.Evaluator.Interface.ErrorException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. ---> System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. ---> System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Am I doing something wrong? 

Kind regards,
