>PMJI. This might be an interesting test with the VFPOLEDB provider. Basically, in the SPROC, you'd just change your SELECT to an 'INTO CURSOR' and then 'RETURN SETRESULTSET('cursorname').

I have been trying to figure out the proper syntax to use such an approach. I have the following code presently and I am not sure if there is something I could do to support that approach:
                oCommand.Connection.Open()

                ' Add all command text
                If oCommandText.Count > 0 Then
                    For Each lcCommandText In oCommandText
                        oCommand.CommandText = lcCommandText
                        oCommand.ExecuteNonQuery()
                    Next
                End If

                oCommand.CommandText = tcSQL + " INTO CURSOR Temp"
                oCommand.ExecuteNonQuery()
                oCommand.CommandText = "RETURN SETRESULTSET(""Temp"")"
                oCommand.ExecuteNonQuery()

                oDataAdapter.SelectCommand = oCommand
                oDataSet = New DataSet

                ' By default, .NET does not add the specific field length, which is needed in XML as at the other end
                ' someone would always get memo field instead of character field
                oDataAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey

                oDataAdapter.Fill(oDataSet)
Basically, the RETURN SETRESULTSET line is the one which is not working. I obtain:

"One or more errors occurred during processing of command."

I guess there is some adjustments that has to be done as I am using the data adapter to fill the dataset. Using that design, is your approach still applicable?
