sql - SELECT columns OVER (PARTITION BY column) -

table being queried (tablea)

suppose want retrieve swimmer , time @ 75th percentile each day.

this trying do:

select tablea.date, tablea.swimmer, tablea.time                 on (partition tablea.date)                 tablea                 rank = ceil(0.75 * num_of_swimmers);

but errors @ on statement.

what's best way data need?

thanks!

your error on clause of windowing function requires order clause.

but assuming num_swimmers , why not return

select    date, swimmer, time tablea  rank = ceil(0.75 * num_of_swimmers)

?

the clause ensure rows returned 75th percentile given day
