Help I have gone brain dead

I have create a table called production. Where production information is entered on each shift for each day (3 shifts). When I first created the table, there was no need to track equipment without production. Now it is!! What I need to do is be able to query the table by line, shift and date for a date range and determine which lines, shifts and date are missing production data. The machines are numbered from 2 to 12 and the column name is LineNum. I have columns named Production, Shift, and EntryDate. I know that I am probably going to feel stupid when I see the fix, but for the life of me, I just don't see how to do it without recordset and then processing it in vbscript.
Thanks in advance,
LeeLee, I'm not sure if I eally understand the problem, but it sounds like the following

SELECT LineNum, Shift, EntryDate
FROM production
WHERE Production IS NULL
AND EntryDate BETWEEN @.begindate AND @.enddate

@.begindate and @.enddate represent the date range you're searching for. This seems awfully simple, though, perhaps I'm misunderstanding the problem?|||If you can, post here the tables structure in order for us to have a good understanding of your situation.

ionut|||I keep playing until I found something that give me an "okay" way of getting the information. I created a table called NumLine with all possible lines in it then joined the two tables. This method returns me data (count) as long as the line has ran at least one shift. The problem is if the line does not run at least one shift, I will not know it. My manager said that he would deal with this short term.

SELECT DISTINCT Prod.ProDate, Prod.Line, Max(Prod.Shift) AS MaxOfShift, Count(Prod.Shift) AS CountOfShift, Prod.ProDate, Prod.Dept

FROM Prod RIGHT JOIN tblNumLine ON Prod.Line = tblNumLine.NumLine

GROUP BY Prod.ProDate, Prod.Line, Prod.ProDate, Prod.Dept, tblNumLine.NumLine

HAVING (((Prod.ProDate) Between 'MMColParamBeg' And 'MMColParamEnd') AND ((Count(Prod.Shift))<3) ))

tblNumLine
NumLine

tblProd
LineNum
Shift
Production
EntryDate

Thanks,
Lee|||Yes! When I thought over what I had accomplished by creating a new table and the structure of the query, end result NOTHING! I could have accomplished the same with a simple Select and Count(Shift) Where Count(Shift) < 3 Group by Shift. What I need is to be able to return missing production even if it is all 3 shifts.

Thanks to all for your patience with an knucklehead,
Lee
