Return Values

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.
