task is to select image data from LONG RAW column of first table
and insert it int ORDImage column of second table.

what I have done so far:

          ORDSYS.ORDSource( TO_BLOB(T1.picture),NULL,NULL,NULL,SYSDATE,1 ),
  FROM table1 T1;

curiously I get the error:
ORA-00932: inconsistent datatypes: expected BINARY got BINARY

Thank You in advance

michelek - I get the same error trying to convert LONG RAW into a BLOB using TO_BLOB. I reckon there's something wrong with the implementation of TO_BLOB. It doesn't seem to do what it says it should!

The best (only!) workaround I can come up with which avoids this ora-932 is to use TO_LOB (not TO_BLOB) to convert PICTURE into a normal BLOB column and then move that directly into the ORDIMAGE, e.g.

create table blob_stage (id number, picture BLOB) ;
insert into blob_stage select t1.id,to_lob(t1.picture) from table1 ;
insert into table2 select id, ORDSYS.ORDImage( ORDSYS.ORDSource( picture, NULL, NULL, NULL, SYSDATE, 1 ), NULL, NULL, NULL, NULL, NULL, NULL, NULL )
 FROM blob_stage ;

which seems OK. Annoyingly if I use TO_LOB with ORDSource I also get the ora-932.
