Name

&& — Returns TRUE if A's 2D bounding box intersects B's 2D bounding box.

Synopsis

boolean &&( geometry A , geometry B );

boolean &&( geography A , geography B );

Descripción

The && operator returns TRUE if the 2D bounding box of geometry A intersects the 2D bounding box of geometry B.

[Note]

This operand will make use of any indexes that may be available on the geometries.

Mejora: 2.0.0 se introdujo soporte de superficies poliédricas.

Availability: 1.5.0 support for geography was introduced.

This method supports Circular Strings and Curves.

This function supports Polyhedral surfaces.

Ejemplos

SELECT tbl1.column1, tbl2.column1, tbl1.column2 && tbl2.column2 AS overlaps
FROM ( VALUES
        (1, 'LINESTRING(0 0, 3 3)'::geometry),
        (2, 'LINESTRING(0 1, 0 5)'::geometry)) AS tbl1,
( VALUES
        (3, 'LINESTRING(1 2, 4 6)'::geometry)) AS tbl2;

 column1 | column1 | overlaps
---------+---------+----------
           1 |       3 | t
           2 |       3 | f
