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);
