Returns 1 if a geometry instance is spatially disjoint from another geometry instance. Returns 0 if it is not.
.STDisjoint ( other_geometry ) other_geometry
Is another geometry instance to compare against the instance on which STDisjoint() is invoked.
SQL Server return type: bit
CLR return type: SqlBoolean
Two geometry instances are disjoint if the intersection of their point sets is empty.
This method always returns null if the spatial reference IDs (SRIDs) of the geometry instances do not match.
The following example uses STDisjoint() to test two geometry instances for spatial disjoint.
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.STDisjoint(@h);
