Two where condition for same column using group by

Question

I am having two tables, t1, t2. My tables and expected result are given below. My table schema is in sqlfiddle

t1:

id    branch_name
1     branch1
2              


        

Answer 1

I think this is the query you are looking for:

SELECT t1.branch_name, 
       COALESCE(SUM(send.vqty), 0) AS send, 
       COALESCE(SUM(receive.vqty), 0) AS received 
FROM t1  
LEFT JOIN t2 AS send on t1.id = send.VBRNCH  
LEFT JOIN t2 AS receive on t1.id = receive.VTOBRN 
GROUP BY t1.branch_name
