SYMPTOMS

When using ActiveX Data Objects (ADO), it is not possible to return two resultsets from a single Oracle package/procedure. If you attempt to return two resultsets, the following error occurs:
"The operation requested by the application is not supported by the Provider"

CAUSE

The Microsoft ODBC driver for Oracle does have this capability, but only for the special feature of returning resultsets from packages/procedures. The driver itself does not support returning multiple results on a single statement. When the Microsoft OLEDB Provider for ODBC attempts to determine if the ODBC driver supports multiple resultsets, it returns FALSE. Because the OLEDB Provider for Oracle does not support the IMultipleResults interface either, that call fails with the above error message.

RESOLUTION

There is no workaround for this problem. When using ADO, you are limited to one resultset returned per Oracle package/stored procedure.

STATUS

This behavior is by design.
