STIntersects (geometry Data Type)
Returns 1 if a geometry instance intersects another geometry instance. Returns 0 if it does not.
Syntax
.STIntersects ( other_geometry )
Arguments
- other_geometry
Is another geometry instance to compare against the instance on which STIntersects() is invoked.
Return Types
SQL Server return type: bit
CLR return type: SqlBoolean
Remarks
This method always returns null if the spatial reference IDs (SRIDs) of the geometry instances do not match.
Examples
The following example uses STIntersects() to determine if two geometry instances intersect each other.
DECLARE @g geometry;
DECLARE @h geometry;
SET @g = geometry::STGeomFromText('LINESTRING(0 2, 2 0, 4 2)', 0);
SET @h = geometry::STGeomFromText('POINT(1 1)', 0);
SELECT @g.STIntersects(@h);
