Visual Studio 2005 - Crystal - Oracle

Question

 I hope that someone will be able to help me with this error I am having.  I have migrated program from Visual Studio 2003 to  Visual Studio 2005.  I'm using DB Oracle. In VS 2003 it functioned perfectly, but in VS 2005 the reports (using Crystal)present the following error: "This field name is not known / Error in formula <subtitulo> / ''De: '+cstr({?v_de})+'Ate'+cstr({?v_ate})' " (The error occurs in the ticket of parametros for the formula)

Other error:"Failed to open a rowset
Details: ADO Error Code: 0x
Source: MicrosoftOLE DB Provider for Oracle
Native Error
Failed to open a rowset"

 

Answer 1

Are you using an identical datasource and/or data connection? For example, if you're using MS ODBC for Oracle for this version, vs the native Orahome9x or Oracle ODBC connector for the other, the table and/or column names may have variations in the translation.

What is highlighted in the formula editor when you do this? "failed to open a rowset" typically means a communication errror, or a syntax error in your field names.
