My data looks like this:

queryable_type   queryable_id 
User             1 
User             2
User             2

I'd like to return dupes so that my result would look like this:

queryable_type  queryable_id count 
User            2            2

I'm assuming some multiple group by but it wasn't working.

This is a most basic group by query:

select queryable_type, queryable_id, count(*)
from the_table
group by queryable_type, queryable_id 
having count(*) > 1
