postgres: Combining filter() with a percentile_cont()
0
Trying to use a filter() clause within a call to percentile_const and I am not sure I can do this. Is there a way? Here's the example query:
select
count(*) as n1,
count(*) filter(where ha >= 0) as n2,
percentile_cont(.9) within group (order by es asc) as p1,
percentile_cont(.9) filter (where ha >= 0) within group (order by es asc) as p2
from mytable where mypid = 123;
The query works fine without the p2 call of course, but you can see what I want to do.

The filter needs to go after the within group part:
select
count(*) as n1,
count(*) filter(where ha >= 0) as n2,
percentile_cont(.9) within group (order by es asc) as p1,
percentile_cont(.9) within group (order by es asc) filter (where ha >= 0) as p2
from mytable
where mypid = 123;
