Invalid Argument for Function

[ErinL]

Hi Everyone!

I have the following in a query to assign a sequence number to each record:

(SELECT Count(*) FROM
[qryPTLActivity] AS T WHERE T.EmployeeID=[qryPTLActivity].[EmployeeID] AND T.PickDateTime <= [qryPTLActivity].[PickDateTime] AND T.PickAisle=[qryPTLActivity].[PickAisle])

I have used this in other databases without issue but for some reason this time I keep getting an "Invalid Argument for Function" error.

Does anyone see a problem with the SELECT statement above? To me it looks just like the one I have that is working.

Thank you in advance.

Notice the ( in front and end, by chance is this a sub-query in a larger query?
Sometimes the SQL view window exceeds the text limit and adds a carrage return.

Also, if the Count is removed, does it work stand-alone?

Is you main query a GROUP BY? if so then this subquery won't work - you'll need to remove the GROUP BY.

If you have other aggregations then you need to use another subquery

Thank you for the quick response.

Yes to both of your questions. It is a sub-query in a larger query and without the statement everything runs fine.

I continued to try different things after I posted and found that when I set a sort order on the fields in the grid (EmployeeID, PickDateTime) the query ran and did what it is supposed to.

However, another problem has surfaced...

Many times a selector will selector in an aisle, move to another aisle and then move back to the original aisle all in the same shift. The way I have it written now, the second time the selector goes to the original aisle the counter continues when I actually want it to reset.

Here is an example of how it looks now:

EmployeeID PickDateTime Aisle Sequence
39 1/6/2014 5:32:00PM 71 1
39 1/6/2014 6:45:47PM 71 2
39 1/6/2014 7:12:54PM 72 1
39 1/6/2014 8:15:56PM 71 3 <---Continues sequence

This is what I would like it to do:

EmployeeID PickDateTime Aisle Sequence
39 1/6/2014 5:32:00PM 71 1
39 1/6/2014 6:45:47PM 71 2
39 1/6/2014 7:12:54PM 72 1
39 1/6/2014 8:15:56PM 71 1 <---Want it to reset

Thank you again!!

With regards the sort order - Sounds like that is a presentation thing - if the dates are not in order, nor will the sequence appear to be(which is in date order)

To solve your next problem - needs some thinking about

OK here we go, this should do the trick

(SELECT count(*) FROM qryPTLActivity as T where EmployeeID=qryPTLActivity.EmployeeID and PickAisle=qryPTLActivity.PickAisle and PickDateTime<=qryPTLActivity.PickDateTime and PickDateTime>=nz((SELECT max(PickDateTime) from qryPTLActivity as t2 where EmployeeID=qryPTLActivity.EmployeeID and PickAisle<>qryPTLActivity.PickAisle and PickDateTime<qryPTLActivity.PickDateTime),(SELECT min(PickDateTime) from qryPTLActivity as t3 where EmployeeID=qryPTLActivity.EmployeeID and PickAisle=qryPTLActivity.PickAisle)))
