Detailed Description

Parse tree node for one or both of a window extent's borders, cf.

<window frame extent> in SQL 2003.

Constructor & Destructor Documentation

◆ PT_borders()

PT_borders::PT_borders	(	const POS &	pos,
		PT_border *	start,
		PT_border *	end
	)

inline

Constructor.

Frames of the form "frame_start no_frame_end" are translated during parsing to "BETWEEN frame_start AND CURRENT ROW". So both 'start' and 'end' are non-nullptr.
