I came here from your other question, and you've done it right. The query result is just telling you that you've created a geometry object. There's no way of showing a geometry object in a table so it just gives the data type in square brackets. You could try converting it back into WKT to confirm that it's worked using the SDO_UTILS.TO_WKTGEOMETRY(geom) function. If that looks ok try using SDO_UTILS.SDO_DISTANCE to calculate distance between them.
