Re: sql question

select sum(case when ordertype='A' then 1 else 0 end) as TotA,
sum(case when ordertype='B' then 1 else 0 end) as TotB,
sum(case when ordertype='C' then 1 else 0 end) as TotC
From Thetable
where Date="May"

This works if you know how many columns(OrderTypes) that you have.  If you
do not know this query can be built dynamically.
