BUG: "Degree of Derived Table" Error When Using Table Name in Select List

ID: Q228943

The information in this article applies to:

SYMPTOMS

When attempting to issue a SQLSetPos() (UPDATE a record) on a SELECT statement that uses table names in the field/column list, you will receive the following error message:

[Microsoft][ODBC driver for Oracle]Degree of derived table does not match column list.
A simple SELECT statement similar to the following causes the error:

SELECT customer.customer_ID, customer.name FROM customer
Also, using alias names for the table, as in the following, also causes the error: 

SELECT a.name FROM customer a


CAUSE

This is a bug in the statement parsing routine for the Microsoft Oracle ODBC driver.
