Returns the smallest number_of_values in the value_expression for each group, with or without ties. BOTTOM is a single-threaded function.

To invoke the time series version of this function, use the GROUP BY TIME clause. For more information, see GROUP BY TIME Clause.

Return Values

The return values are actual values from the input data set.

Nulls are not included in the computation.

Usage Notes

BOTTOM is valid only for numeric data.

WITH TIES implies that the rows returned include the specified number of rows in the ordered set for each timebucket. It includes any rows where the sort key value is the same as the sort key value in the last row that satisfies the specified number or percentage of rows. If this clause is omitted and ties are found, the earliest value in terms of timecode is returned.
