STIntersects (geography Data Type)

Returns 1 if a geography instance intersects another geography instance. Returns 0 if it does not.

.STIntersects ( other_geography )


Is another geography instance to compare against the instance on which STIntersects() is invoked.

SQL Server return type: bit

CLR return type: SqlBoolean

This method always returns null if the spatial reference IDs (SRIDs) of the geography instances do not match.

The following example uses STIntersects() to determine whether two geography instances intersect each other.

DECLARE @g geography;
DECLARE @h geography;
SET @g = geography::STGeomFromText('POLYGON((-122.358 47.653, -122.348 47.649, -122.348 47.658, -122.358 47.658, -122.358 47.653))', 4326);
SET @h = geography::STGeomFromText('LINESTRING(-122.360 47.656, -122.343 47.656)', 4326);

SELECT CASE @g.STIntersects(@h)

WHEN 1 THEN '@g intersects @h'

ELSE '@g does not intersect @h'
