Description
The
&&
operator returns
TRUE
if the 2D bounding box of geometry A intersects the 2D bounding box of geometry B.
This operand will make use of any indexes that may be available on the geometries. |
Enhanced: 2.0.0 support for Polyhedral surfaces was introduced.
Availability: 1.5.0 support for geography was introduced.
This method supports Circular Strings and Curves.
This function supports Polyhedral surfaces.
