  • 0

I’m using MS SQL, and here is my query…

SELECT SUM(Quantity) FROM table1
WHERE [item_no]='0052556'
AND [qty_to_ship] > 0
AND [type] = 5

Interestingly, the query as it stands above returns ‘NULL’…however, if I remove either one of the last 2 conditions it works fine (returns a real number)

to clarify, these queries work fine:

SELECT SUM(Quantity) FROM table1
WHERE [item_no]='0052556'
AND [type] = 5

and

SELECT SUM(Quantity) FROM table1
WHERE [item_no]='0052556'
AND [qty_to_ship] > 0

also note: ‘type’ is a PK, int, not null

what might be causing this?

    Do you have a record that fullfils all the requirement in your (most restrictive) WHERE?

    If not – there’s your anwer.

    Edit: RedFilter’s comment is correct is well. You can add your own logic (ISNULL, etc.) in the SELECT Portion to change NULL to values you like (like 0, for instance)
