Finds the minimum value in a column given by
MIN(expression)
expression.
Finds the maximum value in a column given by
MAX(expression)
expression.
Generates a relative rank for a hypothetical row
PERCENT_RANK(value_list) WITHIN GROUP by dividing that row's rank less 1 by the number
(ORDER BY sort_list)
of rows in the group.
Generates an interpolated value that, if added
PERCENTILE_CONT (percentile) WITHIN
GROUP (ORDER BY sort_list) to the group, would correspond to the
percentile given.
Returns the value with the smallest cumulative
PERCENTILE_DISC (percentile) WITHIN distribution value greater than or equal to
GROUP (ORDER BY sort_list)
percentile.
Generates a rank for a hypothetical row
RANK(value_list) WITHIN GROUP (ORDER (value_list) in a group of rows generated by
BY sort_list)
GROUP BY.
