Check if one MBR is covered by another. Returns 1 if the MBR of the first geometry is entirely contained within the MBR of the second geometry.

MBRCoveredBy is available from MariaDB 12.0.

Syntax

MBRCoveredBy(g1, g2)

Description

Returns 1 if the minimum bounding rectangle of g1 is covered by the minimum bounding rectangle of g2, otherwise 0.

Returns NULL If any argument is NULL, or an argument is an empty geometry.

Examples

SET @g1a = ST_GeomFromText('Point(5 6)');
SET @g1b = ST_GeomFromText('Point(5 11)');
SET @g2 = ST_GeomFromText('Polygon((0 0,0 10,10 10,10 0,0 0))');

SELECT MBRCoveredby(@g1a,@g2), MBRCoveredby(@g1b,@g2);
+------------------------+------------------------+
| MBRCoveredby(@g1a,@g2) | MBRCoveredby(@g1b,@g2) |
