STDisjoint (geometry Data Type)

THIS TOPIC APPLIES TO: yesSQL Server (starting with 2012)noAzure SQL DatabasenoAzure SQL Data Warehouse noParallel Data Warehouse

Returns 1 if a geometry instance is spatially disjoint from another geometry instance. Returns 0 if it is not.

Syntax


.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

Remarks

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);
