    Hi raj,

    What have you tried so far? How does it fail for you?

    See How do I post a question effectively?.

    You should be able to fetch an item from your database using the DBI and DBD::Oracle.

    You may want to pay particular attention to the LongReadLen attribute when using them.

    Hope this helps!


    The way forward always starts with a minimal test.

    Well it depends ...

    Probably you just need to read binmode

    Did you try using the Super Search link here at the monastery, and looking for the word "blob"? I got this node on the second page of results. I expect there are probably more (in case that one doesn't have enough info for you).
