Question

This function that I have does what I want, but just wondering if there is a way to do it in one go:

drop table ##aa
select s.storeid,cast(LEFT(p.paytype,1) as varchar(50)) as Paytype,SUM(amount) as Total
into ##aa
from RPTrs s, rpPay p
where s.storeid=p.StoreID and s.ReceiptNO=p.ReceiptNo 
and trsdate between '1/1/06' and '1/1/13'
group by s.storeid,LEFT(p.paytype,1)

update A set a.paytype=b.currencydesc
from ##aa a, Currencies b
where a.Paytype=b.POSCurrency

select * from ##aa order by Paytype, StoreID

What I am asking is, I want to apply the b.CurrencyDesc to the initial p.paytype. The Paytype just displays C as example but I want it to stand for Cash, and V for Visa and such as it is described in the Currencies table

Seems like you can add a JOIN:

select   s.storeid
       , b.currencydesc as Paytype
       , SUM(amount)    as Total
into     ##aa
from     RPTrs s

join     rpPay p
on       s.storeid=p.StoreID
     and s.ReceiptNO=p.ReceiptNo

join     Currencies b 
on       b.POSCurrency=cast(LEFT(p.paytype,1) as varchar(50))

where    trsdate between '1/1/06' and '1/1/13'
group by s.storeid
       , b.currencydesc

Converted to use explicit join syntax. Can’t tell what table contributes trsdate. And I’m not sure the CAST is needed on the join condition.
