Question

I have two tables

Master   
Detail 

In the Master & Detail table

I get the SUM of Amount Applied in Detail and subtract it from Initial Amount in Master and display in “REMAIN”

select m.ID, m.Init_Amnt, m.Cur_Amnt, max(m.Init_Amnt) - sum(d.Amnt_appl) REMAIN   
from AMASTER m   
left join ADETAIL D on m.ID = d.Master_ID   
group by m.ID, m.Init_Amnt, m.Cur_Amnt  

Is there a way to show only those where the remain in not null OR remain > 0.00

Answer 1

Because this is a filter on an aggregated result, you need a HAVING clause. Depending on your flavour of SQL, something like this:

HAVING ISNULL(max(m.Init_Amnt) - sum(d.Amnt-Appl), 1) > 0

In this, 1 is just a “magic number” to meet the > 0 condition in the case of a null.
