Description:
||Function||Direct Argument Type(s)||Aggregated Argument Type(s)||Return
Type||Partial Mode||Description||
|{{mode() WITHIN GROUP (ORDER BY sort_expression)}}| |any sortable type|same as
sort expression|No|returns the most frequent input value (arbitrarily choosing
the first one if there are multiple equally-frequent results)|
|{{percentile_cont(_fraction_}}) WITHIN GROUP (ORDER BY
{{sort_expression}})|{{double precision}}|{{double precision}} or
{{interval}}|same as sort expression|No|continuous percentile: returns a value
corresponding to the specified fraction in the ordering, interpolating between
adjacent input items if needed|
|{{percentile_cont(_fractions_}}) WITHIN GROUP (ORDER BY
{{sort_expression}})|{{double precision[]}}|{{double precision}} or
{{interval}}|array of sort expression's type|No|multiple continuous percentile:
returns an array of results matching the shape of the _{{fractions}}_
parameter, with each non-null element replaced by the value corresponding to
that percentile|
|{{percentile_disc(_fraction_}}) WITHIN GROUP (ORDER BY
{{sort_expression}})|{{double precision}}|any sortable type|same as sort
expression|No|discrete percentile: returns the first input value whose position
in the ordering equals or exceeds the specified fraction|
|{{percentile_disc(_fractions_}}) WITHIN GROUP (ORDER BY
{{sort_expression}})|{{double precision[]}}|any sortable type|array of sort
expression's type|No|multiple discrete percentile: returns an array of results
matching the shape of the _{{fractions}}_ parameter, with each non-null element
replaced by the input value corresponding to that percentile|
