Question

How can i use same file (like ABC.txt) to write using UTL_FILE.

Currently what is happening is whenever i am trying to write on ABC.txt previous entry is getting deleted or replaced with latest entry. I want all the entries I have made be present.
I am using Oracle 10g PL/SQL.

If I understood you well, you want to append new lines to an existing file (keeping existing content). In this case you need to open the file in append mode:

file_handle = utl_file.fopen( directory, 'file_name', 'a' );

That should be it.
