Coordinates of the vertices of centroid

Question

Hello!
I have a geometry of polygon
and I would to return only coordinates X, Y of the vertices of CENTROID of the input geometry
If I do this return the geometry
SELECT SDO_AGGR_CENTROID(SDOAGGRTYPE(GEOMETRY, 0.005)) FROM LAND_AREA WHERE LAND_AREA.ID =12725
(SDO_GTYPE, SDO_SRID, SDO_POINT(X, Y, Z), SDO_ELEM_INFO, SDO_ORDINATES)
SDO_GEOMETRY(3001, NULL, SDO_POINT_TYPE(579940,339, 4998349,92, 0), NULL, NULL)
But if I do this the query don't work
SELECT t.X, t.Y
FROM
LAND_AREA,
TABLE(SDO_UTIL.GETVERTICES ( SDO_AGGR_CENTROID(SDOAGGRTYPE(GEOMETRY, 0.005)))) t
WHERE
LAND_AREA.ID =12725;
Anyone can please help me with this.
Thank you very much in advance.

Does this give you what you want?
SELECT
    CENTROID_VERTICES.X,
    CENTROID_VERTICES.Y
FROM
        SELECT
            SDO_AGGR_CENTROID(SDOAGGRTYPE(LAND_AREA.GEOMETRY, 0.005)) AS GEOMETRY
        FROM
            LAND_AREA
        WHERE
            LAND_AREA.ID = 12725
    ) CENTROID,
    TABLE(SDO_UTIL.GETVERTICES(CENTROID.GEOMETRY)) CENTROID_VERTICESHope this helps.
