How do I know if the column is BLOB or BFILE?

I have one table which contains five columns. One of the columns is defined as LONG RAW. How do I know whether it is BLOB or BFILE?

My other question is how can I convert BFILE data to BLOB? Is there any utility or do I need to write PL/SQL statements?

Thanks in advance.

Just like the BLOB datatype differs from the BFILE datatype, the LONG RAW datatype is different too. The LONG RAW datatype is not a BLOB or a BFILE. The BLOB and BFILE datatypes replace the LONG RAW datatype.

For information on how to convert, please look at the Oracle documentation.
