You can use UTL_FILE and use standard/basic file I/O calls like fread() and fwrite() - common amongst most (if not all) programming languages.
You can define an external table for the file, and SQL*Load the contents of the file dynamically via a SQL SELECT statement.
You can load the file into a CLOB using DBMS_LOB and then process it - quite useful if the text file is XML as the XMLTYPE supports parsing a a CLOB containing XML.
I want to pick Each object name put in a separate file line by line.That in turn will need to use UTL_FILE to create an external file.
Keep in mind though that your in a database environment with PL/SQL. The very best place for data is inside the database in SQL tables. Not outside as external files. Thus you need to ask yourself whether dealing this way with external files is the best solution, and a robust and scalable one.
Granted, many times from the database side we need to deal with external files. The optimal method usually is to load that file's data into a database table as structured data - data that can be accessed via SQL and sorted, filtered, aggregated and analysed.
To provide a "file" as output - this should ideally be done directly from structured data (SQL tables). And can be done using HTTP (via a web enabled PL/SQL procedure that supplies the file content as a http Mime stream), using FTP (via <i>UTL_TCP</i>) or as a CLOB via a PL/SQL call interface. Using UTL_FILE is not necessarily the only option.
