问题 I am using Oracle 11g r2 . I have a table that stores images as ORDImage : PHOTOS (phot_id integer , phot_filename varchar2(256) , phot_source ordsys.ordimage) And another temporary table that stores an image uploaded by a user as BLOB . INSERT_TEMP (itemp_id integer, itemp_source blob) I want to move the BLOB image to the PHOTOS table only if does not already exists, by comparing the two images. I need to use SQL/MM Still Image methods as ORDImageSignature methods are deprecated in Oracle
