SQL & PL/SQL

Hello All,
I am having a problem that how to display the data of the BLOB column in a table.
by simple select statement it just give me that result.

Table FILEDATA has only two columns:
ID number,
DATA BLOB

Select * from FILEDATA;

ID DATA
1 (BLOB)
2 (BLOB)
3 (BLOB)

Now i want to get the actual string that i have inserted in the DATA(BLOB) column.

Is there any way in SQL Or PL/SQL though which i can get the data in the string format.

Kindly give me the code that will solve the reqired problem.

Thanks in Advance,
Regards,
Omer.
