STDisjoint (geometry Data Type)
Returns 1 if a geometry instance is spatially disjoint from another geometry instance. Returns 0 if it is not.
Składnia
.STDisjoint ( other_geometry )
Arguments
- other_geometry
Is another geometry instance to compare against the instance on which STDisjoint() is invoked.
Return Types
SQL Server return type: bit
CLR return type: SqlBoolean
Uwagi
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.
Examples
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);
