MBRDisjoint

Check if two MBRs are disjoint. Returns 1 if the Minimum Bounding Rectangles of the two geometries do not intersect or touch at all.

Syntax

MBRDisjoint(g1,g2)

Description

Returns 1 or 0 to indicate whether the Minimum Bounding Rectangles of the two geometries g1 and g2 are disjoint. Two geometries are disjoint if they do not intersect, that is touch or overlap.

Examples

SET @g1 = GeomFromText('Polygon((0 0,0 3,3 3,3 0,0 0))');
SET @g2 = GeomFromText('Polygon((4 4,4 7,7 7,7 4,4 4))');
