Remarks

The OGC type of the geometry instance returned by STGeomFromText() is set to the corresponding WKT input.

Examples

The following example uses STGeomFromText() to create a geometry instance.

DECLARE @g geometry;  
SET @g = geometry::STGeomFromText('LINESTRING (100 100, 20 180, 180 180)', 0);  
SELECT @g.ToString();
