AsTextZM (geometry)#
Returns the Open Geospatial Consortium (OGC) Well-Known Text (WKT) representation of a geometry instance augmented with any Z (elevation) and M (measure) values carried by the instance.
Syntax#
.AsTextZM ()
Return type#
nvarchar(max)
Example#
Create 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();
