ST_WITHIN

Syntax

ST_WITHIN(g1,g2)

Description

Returns 1 or 0 to indicate whether geometry g1 is spatially within geometry g2.

This tests the opposite relationship as ST_CONTAINS().

ST_WITHIN() uses object shapes, while WITHIN(), based on the original MySQL implementation, uses object bounding rectangles.

Examples

SET @g1 = ST_GEOMFROMTEXT('POINT(174 149)');

SET @g2 = ST_GEOMFROMTEXT('POLYGON((175 150, 20 40, 50 60, 125 100, 175 150))');

SELECT ST_WITHIN(@g1,@g2);
+--------------------+
| ST_WITHIN(@g1,@g2) |
+--------------------+
|                  1 |
+--------------------+

SET @g1 = ST_GEOMFROMTEXT('POINT(176 151)');

SELECT ST_WITHIN(@g1,@g2);
+--------------------+
| ST_WITHIN(@g1,@g2) |
+--------------------+
|                  0 |
