How to read a blob (binary file) from database ?

 Hi,

I have a binary file that I want to load into a blob column of my database (10.2.0.4).

My datafile contains 10 numbers : 0.01,0.02,0.03,0.04 ....0.10.

But, If I tried to edit this file with a text editor, I obtain something like this :

{®Gáz„?{®Gáz”?¸…ëQ¸ž?{®Gáz¤?š™™™™™©?¸…ëQ¸®?ìQ¸…ë±?{®Gáz´?
×£p=
·?š™™™™™¹?

To load this file into the blob column, I use the following procedure :

PROCEDURE P_LOAD_FILE_MEASUREMENTS(p_cycle_id    in NUMBER,
                    p_variable_id in NUMBER,
                   p_engine_id   in NUMBER,
                   pv_file_name  in VARCHAR2,
                   pv_err_num    out VARCHAR2,
                   pv_err_mess   out VARCHAR2)
is
