HAVING is an important feature. Finally SELECT statement is complete.
I would like to show you another thing about HAVING.

prova=> select sno,qty  from sp  group by sno,qty having qty = 300;
sno  |qty
-----+---
S1   |100
S1   |200
S1   |300
S1   |400
S2   |300
S2   |400
S3   |200
S4   |200
S4   |300
S4   |400
(10 rows)

prova=> select oid,sno,qty  from sp  group by sno,qty having qty = 300;
   oid|sno  |qty
------+-----+---
147004|S1   |100
147001|S1   |200
147000|S1   |300
147002|S1   |400
147006|S2   |300

Solid give me another result. Who are rigth ?

SOLID SQL Editor (teletype) v.02.20.0007
select sno,qty  from sp  group by sno,qty having qty = 300;
SNO                          QTY
---                          ---
S1                           300.
S2                           300.
S4                           300.
3 rows fetched.

Maybe this one is illegal, but it give me a strange output:

prova=> select oid,sno,qty  from sp  having qty = 300;
      |     |               <---------where is the title  ????
------+-----+---
147000|S1   |300
147001|S1   |200
147002|S1   |400
147003|S1   |200
147004|S1   |100
147005|S1   |100
147006|S2   |300
147007|S2   |400
147008|S3   |200
147009|S4   |200
147010|S4   |300
147011|S4   |400
