Signatures & examples

percentile_cont ( fraction double precision ) WITHIN GROUP ( ORDER BY double precision ) → double precision
Computes the continuous percentile, a value corresponding to the specified fraction within the ordered set of aggregated argument values. This will interpolate between adjacent input items if needed.
percentile_cont ( fraction double precision ) WITHIN GROUP ( ORDER BY interval ) → interval
Computes the continuous percentile, a value corresponding to the specified fraction within the ordered set of aggregated argument values. This will interpolate between adjacent input items if needed.
percentile_cont ( fractions double precision[] ) WITHIN GROUP ( ORDER BY double precision ) → double precision[]
Computes multiple continuous percentiles. The result is an array of the same dimensions as the fractions parameter, with each non-null element replaced by the (possibly interpolated) value corresponding to that percentile.
percentile_cont ( fractions double precision[] ) WITHIN GROUP ( ORDER BY interval ) → interval[]
Computes multiple continuous percentiles. The result is an array of the same dimensions as the fractions parameter, with each non-null element replaced by the (possibly interpolated) value corresponding to that percentile.
