Hi
I am doing this:
SELECT distinct cc.trader_id, t.credit_card_number, t.expiry_date, t.name_on_card, sum(to_number(cc.debit_credit,'999999.99')),cc.approval_number, t.business_name FROM credit_card_history AS cc INNER JOIN traders AS t USING (trader_id) GROUP by cc.trader_id, t.credit_card_number, t.expiry_date, t.name_on_card, cc.approval_number, t.business_name having sum(to_number(cc.debit_credit,'999999.99')) != 0
And I expect to get one line as I only have I trader-id in my table(s) but I get this:
1493 4321442143314432 09/09 two duck -200 2 Duck Trading Company
1493 4321442143314432 09/09 two duck 200 5678 2 Duck Trading Company
In fact I don’t actually expect to get any response as the sum should have summed to zero.
Does anyone know what I am doing wrong?
