Long (geography Data Type)

The longitude property of the geography instance.



Return Value

SQL Server type: float

CLR type: SqlDouble


In the OpenGIS model, Long is defined only on geography instances composed of a single point. This property will return NULL if geography instances contain more than a single point. This property is precise and read-only.


This example creates a Point instance and retrieves the longitude of the point.

DECLARE @g geography;
SET @g = geography::STGeomFromText('POINT(-122.34900 47.65100)', 4326);
SELECT @g.Long;
