ID: Q228943

The information in this article applies to:

Microsoft ODBC for Oracle (Build 2.73.7269), version 2.0
Microsoft ODBC for Oracle (Build 2.73.7283.03), version 2.0
Microsoft ODBC for Oracle (Build 2.573.2927), version 2.5
Microsoft ODBC for Oracle (Build 2.573.3513), version 2.5

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.
