SQL Having

The HAVING clause was added to SQL because the WHERE keyword could not be used with aggregate functions.

SQL HAVING Syntax

SELECT column_name, aggregate_function(column_name)
FROM table_name
WHERE column_name operator value
GROUP BY column_name
HAVING aggregate_function(column_name) operator value 

The "custmast"  Then

custcode	custname	city	qty	rate
1	Siva	Srivilliputtur	50	70
2	Bala	Sivakasi	30	56
3	Kanna	Madurai	100	200
4	Vijay	Chennai	30	30
5	Kodee	Sandnes	60	80
5	Kodee	Srivilliputtur	60	30

SELECT CustName,SUM(Qty) FROM custmast
GROUP BY CustName
HAVING SUM(Qty)>110


Output :

custname	qty
Kodee	120
