ST_INTERSECTS¶

Returns TRUE if the two GEOGRAPHY objects or the two GEOMETRY objects intersect (i.e. share any portion of space).

注釈

This function does not support using a GeometryCollection or FeatureCollection as input values.

構文¶

ST_INTERSECTS( <geography_expression_1> , <geography_expression_2> )

ST_INTERSECTS( <geometry_expression_1> , <geometry_expression_2> )

引数¶

geography_expression_1: GEOGRAPHY オブジェクトです。
geography_expression_2: GEOGRAPHY オブジェクトです。
geometry_expression_1: A GEOMETRY object.
geometry_expression_2: A GEOMETRY object.

戻り値¶

BOOLEAN

Usage Notes¶

For GEOMETRY objects, the function reports an error if the two input GEOMETRY objects have different SRIDs.
