Default Correlated Subquery doesn't work

Hi,


ah. Try

.... (SELECT MAX(NextCertDue) FROM ... ) ...


instead of

.... ( SELECT TOP 1 NextCertDue FROM ... ORDER BY NextCertDue )


since it may occur you there is more than just one record with a given
NextCertDue value, and thus, the TOP 1 would return more than one record
(in Jet, by default, in MS SQL Server, through option WITH TIES).



Hoping it may help,

Geesh ! Thanks...

Now I get this problem however....

It seems that it doesn't like using Top 1. Arg!

At most one record can be returned by this subquery. (Error 3354)
A subquery of this kind cannot return more than one record. Revise the
SELECT statement of the subquery to request only one record.

Dear D:

You have misspelled "Gauge" as "Guage"

That should do it!

Whenever I try and run this query a pop-up box comes up asking for the
value of tblWorkLog_Main.GuageID.

Why is this happening. According to the following 2 articles my query
should work. I've never had this problem in SQL Server.

http://support.microsoft.com/?kbid=209066

Both queries work fine independantly (as long as I remove the reference
to tblWorkLog_Main in the sub query if I run it by itself).

I'm using MS Access 2000.


SELECT WorkLogID, GaugeID, NextCertDue,

(SELECT TOP 1 NextCertDue
FROM tblWorkLog wl
WHERE GaugeID =tblWorkLog_Main.GuageID
AND
WorkLogID 1
ORDER BY NextCertDue Desc) AS DueDate


FROM tblWorkLog tblWorkLog_Main
ORDER BY GaugeID, NextCertDue DESC;
