Description

Determines whether the geometry shape1 intersects with the geometry shape2.

Syntax

ST_INTERSECTS( <shape1>, <shape2> )

Parameters

Parameters	Instructions
<shape1>	The passed geometry used to determine whether it intersects with shape2
<shape2>	The passed geometry used to determine whether it intersects with shape1

Return Value
