The first example creates a geometry instance with the SRID value 13 and uses STSrid to confirm the SRID.

DECLARE @g geometry;  
SET @g = geometry::STGeomFromText('POLYGON((0 0, 3 0, 3 3, 0 3, 0 0))', 13);  
SELECT @g.STSrid;

The second example uses STSrid to change the SRID value of the instance to 23 and then confirms the modified SRID value.

SET @g.STSrid = 23;  
SELECT @g.STSrid;
