Hi,
[code]
SQL> select job, count(*)
from scott.emp
group by job
order by 1;
[/code]
[code]
SQL>select job, count(distinct deptno), count(*)
from scott.emp
group by job
order by 1;
[/code]
[code]
select job, deptno, count(*)
from scott.emp
group by job,deptno
order by 1,2;
[/code]
In order to put that in a PLSQL procedure, for each SQL you can do
set serverout on
[code]
begin
for i in ( “yoursql” )
loop
dbms_output.put_line( “attributes” );
end loop;
end;
[/code]
hope this help.
