Subtraction Issue

Subtraction Issue

(OP)
I have a query that has an inner join. everything works fine except I'm trying to subtract two fields to get a remaining balance. both fields are int.

CODE -->

SUM(MY_TABLE.TRANSFERED) AS TRANSFERED
,SUM(MY_TABLE.RECEIVED - MY_TABLE.TRANSFERED) AS REMAINING 

what is happening is the value will not zero out if it's supposed to be a 0

e.g.

so the sum of RECEIVED = 4074 and the sum of TRANSFERED = 4074 the remaining amout is showing 4074 and not 0

what causes this and how can I fix it ?

any help would be appreciated

thanks

RE: Subtraction Issue

do

CODE

SUM(MY_TABLE.TRANSFERED) AS TRANSFERED
,SUM(MY_TABLE.RECEIVED) - sum(MY_TABLE.TRANSFERED) AS REMAINING 

But to verify that indeed what you expect is correct do

CODE

SUM(MY_TABLE.TRANSFERED) AS TRANSFERED
,SUM(MY_TABLE.RECEIVED) AS RECEIVED
,SUM(MY_TABLE.RECEIVED) - sum(MY_TABLE.TRANSFERED) AS REMAINING
