Dear members ,
I am trying to brush up my SQL (Oracle) , and before I dust my books ,
I
decided to take an assignment :-
Q) Get all the suppliers and the total number of parts they are supplying.
table s :-
s# not null varchar2(3)
s_name varchar2(7)
status number
city varchar2(6)
table sp :-
s# not null varchar2(3)
p# not null varchar2(3)
qty number
s# means supplier's ID and p# means product ID
This is what I tried : - select count(p#) from s,sp where s.s#=sp.s# group by
sp.s#
But when I tried select sname,count(p#) from s,sp where s.s#=sp.s# group by
sp.s# ,
I am shown an error that says something like : " Single-group .... "
Please help me.
Thanks in advance,
