STGeomFromText (geography Data Type)
Returns a geography instance from an Open Geospatial Consortium (OGC) Well-Known Text (WKT) representation augmented with any Z (elevation) and M (measure) values carried by the instance.
This geography data type method supports FullGlobe instances or spatial instances that are larger than a hemisphere.
Applies to: SQL Server (SQL Server 2008 through current version), Azure SQL Database.
The following example uses STGeomFromText() to create a geography instance.
DECLARE @g geography; SET @g = geography::STGeomFromText('LINESTRING(-122.360 47.656, -122.343 47.656)', 4326); SELECT @g.ToString();
