Formatting SQL query as of iSQL*PLUS query output format through PL/SQL

Question

This is my procedure through which i m sending an e-mail. In my e-mail i want to show output from error log query. I can show it in simple text but i want the output for the error log to be formatted as the query result is formated in iSQLPlus.
In simple words instead of the message i want to send the query result which is formatted as iSqlPlus query output. Thankx in advance. Please provide a simple solution that iSqlPlus engine recieves my any given query and gives the formatted output for that query in the e-mail
DECLARE
conn utl_smtp.connection;
v_log number;
BEGIN
conn := demo_mail.begin_mail(
sender => '<sender-email>',
recipients => '<recipient-email>',
subject => 'HTML E-mail Test',
mime_type => 'text/html');
</h1>
-- This method will be used for oracle error reporting');
demo_mail.write_text(
conn => conn,
message => '<h1>Hi! This is a <i>test msg</i>);
demo_mail.end_mail( conn => conn );
END;

    select * from
    (select rownum r1, p.promo_id, promo_name from promotions p where rownum <5)
    full outer join
    (select rownum r2, w.warehouse_id from warehouses w where rownum <4)
   on (r1 = r2)

        R1   PROMO_ID PROMO_NAME                   R2 WAREHOUSE_ID

         2          2 blowout sale                  2            2

I am joining on ROWNUM, Do you want every row from emp related to every row from stocks (like a cartesian join)?
Trying to understand the requirement.
