ACC: ORDER BYs Must Be Output Columns in DISTINCT Queries
ID: Q96895
|
The information in this article applies to:
-
Microsoft Access versions 1.0, 1.1, 2.0, 7.0
SYMPTOMS
Moderate: Requires basic macro, coding, and interoperability skills.
If you create a query and use the DISTINCT predicate in conjunction
with the ORDER BY clause, the fields that are being ordered must be
output columns. If the ORDER BY fields are not output columns, you
may receive the following error message:
ORDER BY clause ([Table Name].[Field Name]) conflicts with DISTINCT.
RESOLUTION
Use the DISTINCTROW predicate or remove the specified field from the ORDER
BY clause.
MORE INFORMATION
Steps to Reproduce Behavior
Follow these steps in the sample database NorthWind (or NWIND.MDB in
versions 1.x and 2.0):
- Create a new query and add the Customers table.
- Place the Address and City fields in the query design grid.
Query: MyQuery
----------------------
Field Name: Address
Sort: Ascending
Show: False
Field Name: City
Show: True
- On the View menu, click SQL. Modify the SQL statement as follows:
SELECT DISTINCT Customers.City
FROM Customers
ORDER BY Customers.Address;
- Run the query. Note that you receive the following error message:
ORDER BY clause (Customers.Address) conflicts with DISTINCT
To resolve this, you must Show the Address field or use DISTINCTROW in
place of DISTINCT in the SQL statement.
