Ora-13497 during SDO_GEOR.MOSAIC

Question

we are testing sdo_geor.mosaic on 2 georasters but we get this error:
SQL> DECLARE
2 GR SDO_GEORASTER;
3 BEGIN
4 GR := SDO_GEOR.INIT('MO');
5 SDO_GEOR.MOSAIC('GEORASTER_TABLE', 'GEORASTER', GR, NULL);
6 INSERT INTO MO (GEORASTER) VALUES (GR);
7 COMMIT;
8 END;
9 /
DECLARE

The georasters are valid, the metadata of 1 of them:

we are using Oracle Database 10g Enterprise Edition Release 10.2.0.1.0
So, is there any solution?
Thanks in advance,

Answer 1

Michael,
1. have you properly created the RDT table, called "MO"? if not yet, please follow section 3.1 of the GeoRaster guide to do it first.
2. In section 3.2 of the GeoRaster guide, "you must register an initialized GeoRaster object in the GeoRaster system views by inserting the GeoRaster object into a GeoRaster table, and do this before you perform any other operations on the GeoRaster object. Any GeoRaster operations that need to manipulate the raster data table raise an exception if the source or target GeoRaster object is not registered." In other words, you need to INSERT your GR into a physical georaster table FIRST, then retrieve it back into your plsql block, then do sdo_geor.mosaic, then update that GR object in the table. For this, please follow the sample code in the sdo_geor.mosaic in chapter 4.
hope this helps,
Jeffrey
