Unknown Database Connector Error using Oracle stored procedures


We are using an Oracle database for the first time with our Crystal Reports, and I am attempting to modify a report to use a new stored procedure. When I attempt to add either the new procedure, or to add a new copy of the existing procedure, I get an error message:

Unknown Database Connector Error

If I remove the existing procedure first (leaving no database objects at all), and then attempt to add back exactly the same stored procedure that I just removed, I get a different error message:

Database Connector Error: '42000:[Oracle][ODBC]Syntax error or access violation'

Neither of these errors is particularly helpful. The stored procedure in question works as is. I can run it in SQL Developer, and it also executes within the existing report if I run it. Unfortunately, it needs to be modified and given a new name, so I need to be able to add the new stored procedure to the report.

The operating system is Windows XP Professional version 2002 SP3. The Oracle version is 11g ( Crystal reports version is Crystal Reports 2008 ( The stored procedure returns a refcursor. The ODBC connection is created using the "Oracle in OraClient11g_home1" driver. When I test the connection, it tells me it was successful.

If it matters, the report is a Saba report.

Can anyone shed any light on what the problem is and how to fix it. If the solution is to upgrade the Windows version, that is under the control of our tech support and there is no information available as to when it will happen.
