To get more information about the cause of an “ODBC–call failed.” error we can loop through the DBEngine.Errors
collection and see if there are other messages that might be a bit more descriptive. For example, with the code
qdf.Connect = strConnectionString
qdf.SQL = " EXEC [dbo].[SAMPLE_TEST]"
qdf.ReturnsRecords = True
On Error GoTo oops
Set rst = qdf.OpenRecordset
Debug.Print rst!RecordCount
rst.Close
Set rst = Nothing
Exit Sub
oops:
Dim dbeError As Error
For Each dbeError In DBEngine.Errors
Debug.Print "(" & dbeError.Number & "): " & dbeError.Description
Next
End Sub
we might see the following in the VBA Immediate window:
(229): [Microsoft][ODBC SQL Server Driver][SQL Server]The EXECUTE permission was denied on the object 'SAMPLE_TEST', database 'myDb', schema 'dbo'.
(3146): ODBC--call failed.
Certainly
The EXECUTE permission was denied on the object ‘SAMPLE_TEST’, database ‘myDb’, schema ‘dbo’.
is considerably more helpful than just
ODBC–call failed.
