STSrid (geography Data Type)

STSrid is an integer representing the spatial reference identifier (SRID) of the instance.


.STSrid

SQL Server type: int

CLR type: SqlInt32

This property can be modified.

For more information on SRIDs, see Spatial Reference Identifiers (SRIDs).

The first example creates a geography instance with the SRID value 4326 (WGS84) and uses STSrid to confirm the SRID.

DECLARE @g geography;
SET @g = geography::STGeomFromText('LINESTRING(-122.360 47.656, -122.343 47.656)', 4326);
SELECT @g.STSrid;

The second example uses STSrid to change the SRID value of the instance to 4267 (NAD27) and then confirms the modified SRID value.

SET @g.STSrid = 4267;
SELECT @g.STSrid;
