I'm looking to perform a sum calculation on a SQL table to find the quantity of a particular stock item held against a particular salesperson up to and including a specific date.
I'm able to perform the sum function to find the quantities on a Salesperson/item basis whenever I do not factor in the date range criteria, but as soon as i add that aspect, it all goes a bit pear shaped! Here is my code so far:
SELECT Salesperson, Item No, Sum(Quantity) AS 'Quantity'
FROM dbo
WHERE (Location Code='VAN')
GROUP BY Salesperson, Item No,
HAVING (Registering Date<={ts '2017-05-03 00:00:00'})
The location code = VAN filter is required to ensure it ignores Warehouse quantities.My SQL knowledge is limited to the few instances I run into it at work and my interaction is largely based through Microsoft Query in Excel. When looking at the above code, i figured that the 'Registering date' criteria should be in the 'WHERE' section, however when i add the criteria using the options available in Microsoft Query, it creates the 'HAVING' line.
If anyone could provide any pointers, it would be much appreciated!
Cheers
Peter
