Hello people,
I have a table "tbl" with fields ID, f1, f2.
I want to know if there are repeated rows for each value of f1, with
a condition for f2.

I have:
select f1, count (*) as quantity from tbl
where f2="myCondition"
group by f1


There I have all values, but I only want to know if in this query any
row has a value of quantity > 1

Ideas ?
Thanks !
