Convert DD to DMS using sdo_coord_ops = 101 returns ORA-13199

Question

Hi,
I need to convert lat/long DD to DMS.
There is an operation in sdo_coord_ops (coord_op_id = 101) to do that but returns ORA-13199 when i try sdo_cs.add_preference_for_op
I know that i can do that conversion with a function (Re: SDO_UTIL.BEARING_TILT_FOR_POINTS in a Select statement - thanks Simon!).
How i know which operation that exists in sdo_coord_ops are actually implemented or not?
Thanks!

Well, if you check the documentation it's quite clear: Coordinate Systems (Spatial Reference Systems)
Of course you could also run something like this:
select co.coord_op_id,
       co.coord_op_name,
       com.coord_op_method_name,
       com.is_implemented_forward,
       com.is_implemented_reverse
from sdo_coord_ops co,
     sdo_coord_op_methods com
where co.coord_op_id = 101 and
      com.coord_op_method_id = co.coord_op_method_id;
0 = not implemented, 1 = implemented.
