QUESTION POSED ON: 05 February 2007
I have a control file and a CSV file, and now I have a form where I can browse these two files and on submission of this form I want to write a PL/SQL procedure which can actually perform the action of a SQL Loader and then load that Excel file into the database table specified in the control file.
Actually I can do that from the command prompt like this: c:sqlldr username/password control="control file path"

I want the process for how I can execute this command using a PL/SQL procedure. Thanks in advance.

In Oracle 9i, there is no direct way to execute an operating system command directly from PL/SQL. But you can write an external file using Perl, C or C++, using sys.DBMS_PIPE.

If you are using Oracle 10g, you can use sys.DBMS_SCHEDULER. The script below shows an example of how to set up a dbms_scheduler to execute the command '/app/oracle/x.sh':

BEGIN
  dbms_scheduler.create_job(job_name        => 'myjob',
                            job_type        => 'executable',
                            job_action      => '/app/oracle/x.sh',
                            enabled         => TRUE,
                            auto_drop       => TRUE);
END;
/

exec dbms_scheduler.run_job('myjob');
