Around the QTY as before (and just in case there is no occurrence and the
SUM is NULL additionally around the whole expression)

Subject: Re: SQL question combine 3 queries into 1?
I've had to use ifnull on quantities before. Where do I put ifnull in the
case statements? Thank you.
Select Sum(Case When Substr(Tlc, 1, 1) = '9' Then QTY End),
Sum(Case When Substr(Tlc, 1, 1) = '6' Then QTY End),
Sum(Case When Substr(Tlc, 1, 1) = '1' Then QTY End)
