Order by Error but no Order By Clause (1 Viewer)

I've been fighting with this problem for a while now. I have a union query that joins the results of about 10 select queries that are all structured the same way but for some reason, two of the select queries are causing an error. I can run all of the queries individually except two of them error out.

The error is:
"A column has been specified more than once in the order by list."

That would be easy to fix but there is NO ORDER BY in the code for these queries! I've narrowed the problem down to the Where clause. When I eliminate part of that clause the error stops. Other than the tables, there is no difference between the clause in the queries that work and the clause in the queries that error out. How do I track this down so I can fix it? Here is the code for one of the queries that isn't working:

Code:
SELECT NorthCompressorRoundT.LoggedAt AS [Time], NorthCompressorRoundT.CompressorID AS ID, NorthCompressorRoundT.CompressorIntegrity AS Integrity, Null AS Integrity2, NorthCompressorRoundT.Status, NorthCompressorRoundT.Notes AS Comments, NorthCompressorT.Type
FROM NorthCompressorT INNER JOIN (LatestCompressorRoundQ INNER JOIN NorthCompressorRoundT ON (LatestCompressorRoundQ.Time = NorthCompressorRoundT.LoggedAt) AND (LatestCompressorRoundQ.ID = NorthCompressorRoundT.CompressorID)) ON NorthCompressorT.AssetNumber = NorthCompressorRoundT.AssetNumber
WHERE (((NorthCompressorRoundT.LoggedAt)=[LatestCompressorRoundQ]![Time]) AND ((NorthCompressorRoundT.CompressorIntegrity)="Known Defect" Or (NorthCompressorRoundT.CompressorIntegrity)="New Defect" Or (NorthCompressorRoundT.CompressorIntegrity)="DFM"));

Are any of the entities that you're selecting FROM, linked sql server objects?

May or may not be contributing to issue but do all the queries use a field named Time? Time is a reserved word and advise not to use reserved words as names.

Remove NorthCompressorRoundT.LoggedAt = [LatestCompressorRoundQ]![Time] from WHERE clause because already have these two fields linked in INNER JOIN clause.

Yes, the tables (ending with a "T") are linked sql server objects but the queries (ending with a "Q" are local.

Are you able to successfully double-click on the linked objects (ending in T) and they open correctly?

Ok thanks ... That's where I was going with all of these questions. That error is not from MS Access...it's from SQL Server. Which tells me either there is something wrong with the sql server objects you've been given (most likely Views), or (since you're able to successfully 'run' them by opening them in MS Access) something unique about those objects in combination with your access Union. I will post back if I come up with any ideas on this.. Thanks for all the info.

Thanks for trying Isaac,

One weird thing is I have about 8 or nine other queries that are coded the same with tables linked to the same server database and they don't produce that error. Only difference is they are pointing to different tables. I wonder if it has something to do with the ODBC version is a bit old on these links. Perhaps I'll try updating them and see if that clears it up.

It definitely seems like, if it were a problem with the SQL Server View definition, a) I'm not sure how create view even worked, though I don't have time to test now, and b) If that were the case you shouldn't have been able to run the view by opening the Access linked table...

Weird.

You could also post the entire SQL of your final query in case that sheds any light to anyone?

If you open a form or query and manually sort it, Access saves that action when you close the object. If a change is made to the table schema, you may later get errors.

Open the query in design view and look at the properties to see if there is a saved sort on a column that is no longer in the query.

Thanks Pat,

I actually copied the SQL code from the query into an entirely new query for troubleshooting and I get the same error. That probably rules out any saved actions on the object.

If the tables are SQL Server (or other RDBMS or spreadsheet), try relinking the table. Access automatically updates source table changes when the source table is Jet/ACE but it does not update the definitions automatically for other linked tables.
