Applies to: SQL Server (SQL Server 2008 through current version), Azure SQL Database.

.STDisjoint ( other_geography )

other_geography

Is another geography instance to compare against the instance on which STDisjoint() is invoked.

SQL Server return type: bit

CLR return type: SqlBoolean

Two geography 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 geography instances do not match.

The following example uses STDisjoint() to test two geography instances to see if they are spatially disjoint.

DECLARE @g geography;
DECLARE @h geography;
SET @g = geography::STGeomFromText('LINESTRING(-122.360 47.656, -122.343 47.656)', 4326);
SET @h = geography::STGeomFromText('POINT(-122.34900 47.65100)', 4326);
SELECT @g.STDisjoint(@h);
