Re: [MS_AccessPros] QUERY TOO COMPLEX

 

Thanks John. The suggestion did not make a difference.

First thing to try is to give RptMultcounts a short alias - maybe RM.  That will shorten your SQL statement significantly.

SELECT RM.IDNo, RM.Win1, … etc.

FROM (((((RptMultCounts AS RM LEFT JOIN Skppost ON RM.Win1 = Skppost.[No]) LEFT JOIN …

Copy off to Notepad and do a Replace of all occurrences of RptMultCounts (except the first one in the FROM clause) with RM, then add the alias.

This worked perfectly in Access 2007.

Ade-

Please post the SQL from one of the queries that's failing.

The query engine / optimizer does change some between releases.  I has to be able to "compile" your SQL in its buffer before it can execute it.  It may have been close to the limit in 2007, but now won't fit in 2010, but there's no indication other than the Too Complex message.

There are things you can do to try to reduce the compile size - such as substitute short alias names.

Kindly assist. I have some queries which worked perfectly on an older computer. I get the message QUERY TOO COMPLEX when I tried running some of them on a newer computer.

Would you know how to resolve this ?

Thanks.

Ade.
