    Is there any way to know if you have data in a BLOB field?
    I can't visualize the field with my SQL* Plus worksheet,but maybe I can guess just if I have data or not in it...
    Thanks

    Yes. Assume that your table is calle BLOB_TABLE and the BLOB column is called PHOTO.

    Run:

    Code:
    select DBMS_LOB.GETLENGTH(PHOTO) from BLOB_TABLE;
    If there is data, then the integer returned will be a big number.
