Same advice as before - shorten all the alias names. For example, instead of using AS DMSkips_1, use something like DMS1 or S1.

Hi John,
i have an issue similar to the previous one. The expression DMSkips is what repeats and I am trying to shorten this. Any hint regarding this one expressed below ?
FROM ((((((DM LEFT JOIN DMSkips ON DM.Win1 = DMSkips.Number) LEFT JOIN DMSkips AS DMSkips_1 ON DM.Win2 = DMSkips_1.Number) LEFT JOIN DMSkips AS DMSkips_2 ON DM.Win3 = DMSkips_2.Number) LEFT JOIN DMSkips AS DMSkips_3 ON DM.Win4 = DMSkips_3.Number) LEFT JOIN DMSkips AS DMSkips_4 ON DM.Win5 = DMSkips_4.Number) LEFT JOIN DMSkips AS DMSkips_5 ON DM.Win6 = DMSkips_5.Number) LEFT JOIN GameSumCountRank ON DM.Sum = GameSumCountRank.Sum
Thanks.
Ade.

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.

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.
