query help

[userZ]

From tableA, need a query to get to something like TableB.
TableA:

ID, ProdID, BatchID,ProdType,inpdate, inptime, CarrierID, CarrierName, delivered, comments, fieldn,fieldn+1,location

TableB:

ID, prodID, BatchID, MAx(inpdate+inptime), CarrierName, delivered, location
where delivered is "yes" and location is "loc1"

In Access, i tried multiple queries to get it done. I like one query that does it. It may use less resources.

Readers really need to know what you are trying to accomplish. you are telling us HOW you are doing something. We need to understand what that something is.

TableA and tableB don't give many hints as to the purpose of the tables and database.

TableA stores product shipment information. inpdate, inptime are the entered date and time for each product.

Need to query the last , MAX(date+time), entry for each product where the "delivered" is yes and location is "loc1". The fields to query are shown in TableB.

So in this case, what will be the best solution?
