rowsBetween (WindowSpec)

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.
