Defines the frame boundaries, from start (inclusive) to end (inclusive).
Both start and end are relative positions from the current row. For example, 0 means "current row", -1 means the row before the current row, and 5 means the fifth row after the current row.
Syntax
rowsBetween(start, end)
Parameters
| Parameter | Type | Description |
|---|---|---|
start |
int | Boundary start, inclusive. The frame is unbounded if this is Window.unboundedPreceding, or any value less than or equal to max(-sys.maxsize, -9223372036854775808). |
end |
int | Boundary end, inclusive. The frame is unbounded if this is Window.unboundedFollowing, or any value greater than or equal to min(sys.maxsize, 9223372036854775807). |
Returns
WindowSpec
Notes
Use Window.unboundedPreceding, Window.unboundedFollowing, and Window.currentRow to specify special boundary values rather than using integral values directly.
