This example converts Geodetic coordinates in the “WGS 84” spatial reference system to MGRS.
SELECT TO_MGRS( new ST_GEOMETRY('ST_POINT', 30, 45), (select SRTEXT from sysspatial.spatial_ref_sys where srid = 1619), 5);
Returns:
TO_MGRS(NEW ST_GEOMETRY('ST_POINT', 30, 45),<Scalar Subquery>,5 ) ----------------------------------------------------------------- 36TTQ6355387329
