ST_WITHIN¶
Returns true if the the first geospatial object is fully contained by the second geospatial object. In other words:
The first GEOGRAPHY object
g1
is fully contained by the second GEOGRAPHY objectg2
.The first GEOMETRY object
g1
is fully contained by the second GEOMETRY objectg2
.
Calling ST_WITHIN(g1, g2)
is equivalent to calling ST_CONTAINS(g2, g1)
.
Although ST_COVEREDBY and ST_WITHIN might seem similar, the two functions have subtle differences. For details on the differences between 《covered by》 and 《within》, see the Dimensionally Extended 9-Intersection Model (DE-9IM).
참고
이 함수는 GeometryCollection 또는 FeatureCollection을 입력 값으로 사용하는 것을 지원하지 않습니다.
