# ST_INTERSECTS¶

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

참고

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

참고 항목:

ST_DISJOINT

## 구문¶

ST_INTERSECTS( <geography_expression_1> , <geography_expression_2> )

ST_INTERSECTS( <geometry_expression_1> , <geometry_expression_2> )


## 인자¶

geography_expression_1

GEOGRAPHY 오브젝트입니다.

geography_expression_2

GEOGRAPHY 오브젝트입니다.

geometry_expression_1

A GEOMETRY object.

geometry_expression_2

A GEOMETRY object.

BOOLEAN.

## Usage Notes¶

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

TO_GEOGRAPHY('POLYGON((0 0, 2 0, 2 2, 0 2, 0 0))'),
TO_GEOGRAPHY('POLYGON((1 1, 3 1, 3 3, 1 3, 1 1))')
);
