thanks for the reply,
I am unable to insert data other than 0-9 and a-f into BLOB, as it is giving 'ORA-00911: invalid character' message.
So does it only allow Hexadecimal numbers.
If so, why it is allowing Hexadecimal numbers when it's name is Binary LOB?
And one more thing when I take a word document as InputStream through JDBC and insert it into BLOB how I am able to insert word document into BLOB, as word document contains characters other than 0-9 and a-f.
I am not getting low level clarity as how data is managed in BLOB, can you give some clarity on this.
