Examples

The following example creates a Point instance that contains Z (elevation) and M (measure) values. STAsText() selects the WKT values, (1 2); AsTextZM() selects the same WKT values and also returns the values for Z and M, yielding (1 2 3 4).

DECLARE @g geometry;  
SET @g = geometry::STGeomFromText('POINT(1 2 3 4)', 0);  
SELECT @g.STAsText();  
SELECT @g.AsTextZM();
