ST_DISJOINT

Syntax

ST_DISJOINT(g1,g2)

Description

Returns 1 or 0 to indicate whether geometry g1 is spatially disjoint from (does not intersect with) geometry g2.

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

ST_DISJOINT() tests the opposite relationship to ST_INTERSECTS().

Examples

SET @g1 = ST_GEOMFROMTEXT('POINT(0 0)');

SET @g2 = ST_GEOMFROMTEXT('LINESTRING(2 0, 0 2)');

SELECT ST_DISJOINT(@g1,@g2);
+----------------------+
| ST_DISJOINT(@g1,@g2) |

SET @g2 = ST_GEOMFROMTEXT('LINESTRING(0 0, 0 2)');

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