ACC2: Constant in ORDER BY Clause of Union Query Is Ignored

ID: Q123587


The information in this article applies to:
  • Microsoft Access 2.0


SYMPTOMS

Novice: Requires knowledge of the user interface on single-user computers.

When you run a union query containing an ORDER BY clause that references a constant, the constant value is ignored.

If the reference to the constant is the only item in the ORDER BY clause, no ordering of the data is performed. If the ORDER BY clause contains additional items, however, ordering by the other items is performed.


RESOLUTION

Create another query based on the union query, and then sort the data in the new query.


STATUS

Microsoft has confirmed this to be a problem in Microsoft Access version 2.0. This problem no longer occurs with the Microsoft Jet database engine version 2.5, which is available with the Microsoft Access version 2.0 Service Pack.

MORE INFORMATION

Steps to Reproduce Problem


  1. Start Microsoft Access and open the sample database NWIND.MDB.

          SELECT DISTINCTROW Employees.[Last Name], Employees.Title,
           "Emp" AS Source
          FROM Employees
          UNION SELECT DISTINCTROW Customers.[Contact Name],
           Customers.[Contact Title], "Cust"
          FROM Customers ORDER BY [Source]; 


  3. Run the query. Note that the data is not ordered as you expect.
