BUG: RDO Doesn't Work with Schema and Oracle Stored Procedures

 Last reviewed: February 4, 1998
Article ID: Q180198
The information in this article applies to:
  • Microsoft Visual Basic Enterprise Edition for Windows, version 5.0

SYMPTOMS

When using RDO v2.0 with Microsoft Oracle ODBC Driver v2.0, you cannot use schema names when calling Oracle stored procedures.

CAUSE

This bug has been traced back to the way RDO v2.0 implements the ODBC API call SQLProcedureColumns. When a fundamental change was made to the Microsoft Oracle ODBC Driver (moving from v1.0 to v2.0), this bug in RDO v2.0 was exposed.

RESOLUTION

There is no workaround for this bug in RDO v2.0. If you need to access Oracle stored procedures using schema, you have to switch to ADO v1.5 (or later) or use the Microsoft Oracle ODBC Driver v1.0. The Microsoft Oracle ODBC Driver v1.0 shipped with Visual Basic 5.0 Professional and Enterprise editions. The version number of this older ODBC driver is 2.00.006325.

STATUS

Microsoft has confirmed this to be a bug in VB 5.0/RDO 2.0. We are researching this bug and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

This bug was identified and reproduced using the Microsoft Oracle ODBC Driver v2.0 (from the MDAC 1.5 stack: see the REFERENCES section below for Knowledge Base article Q175018), Oracle v7.3, and RDO v2.0 from Visual Basic Enterprise Version 5.0. Other versions of these components may produce different results.

As noted above, using the Microsoft Oracle ODBC Driver v1.0 allows you to access Oracle stored procedures with schema names. You should note, however, that this is not recommended; it is recommended that you switch to ADO v1.5 (or later). Please the REFERENCES section below for details about using ADO to access Oracle stored procedures.
