Access 07 - Cumul Sum Field that starts at 0 each Day

Posted on 2014-02-16

Hello All

I have to get a query that includes a cumulative sum field of TransAmt that starts at zero for each day and accumulates the Day's total for each consecutive ShiftID.

Attached is a stripped down db.  

I'm too stupid to figure out how to accomplish this in 1 query so it takes me 3 to get to this point BUT in the qry_CumulSum_Step3 my column or field y: is accumulating it by ShiftID but I tried copying that query to a qry_TEST and adding a criteria for the field [BusDay] (which is my Day field) but I get #Error.

My code is
SELECT qry_CumulSum_Step2.ShiftID, qry_CumulSum_Step2.BusDay, qry_CumulSum_Step2.CashFdActID, qry_CumulSum_Step2.TransAmtTtl, Val(DSum("TransAmtTtl","qry_CumulSum_Step2","ShiftID <=" & [a].[ShiftID] & " AND #[BusDay]# <=#" & [a].[BusDay] & "#")) AS y
FROM qry_CumulSum_Step2 INNER JOIN qry_CumulSum_Step2 AS a ON (qry_CumulSum_Step2.ShiftID = a.ShiftID) AND (qry_CumulSum_Step2.BusDay = a.BusDay);

Cumulative sums always need more then one query, so it is impossible to do it in one query. You can, of course, use nested queries. It will look like one query, but you will have one select inside another select. Dsum is also query, so you should count it also :)
