plsql - How do i format Oracle Output for this Block? -


i'm stuck on block of statements , don't know how program output when code runs show amount of payment $10.00 , balance remaining in same format. code prompts me twice idpledge... i've got markup in code topics don't quite understand. using oracle 11g 2e , book isn't helpful. if there recommendation beginner books or resources listening (reading). code below:

set serveroutput on;  declare   pay_num           number(2) := 0; /*initialize 0 */   loop_count        number(2) := 12; /*intialize max number of months */   pay_amt           number(8,2);   pledge_bal        number(8,2);   v_pledgeamt       number(8,2);   start_date        date := '04-oct-2012';   due_date      date;   v_due_date        varchar2(15);  begin    select pledgeamt v_pledgeamt   dd_pledge   idpledge=&idpledge;    pay_amt := (v_pledgeamt / loop_count);   due_date := start_date;   pledge_bal := (v_pledgeamt - pay_amt);    in 1..loop_count loop      pay_num := pay_num + 1;     v_due_date := to_char(due_date, 'mm-dd-yyyy');     due_date := add_months(due_date, 1);     pledge_bal := (pledge_bal - pay_amt);      dbms_output.put_line (       'payment num: ' || pay_num       || ' ' || 'due date: ' || v_due_date       || ' ' || 'amount due: ' || pay_amt         || ' ' || 'balance: ' || to_char(pledge_bal, '$')); /* how format $*/    end loop; end;

as mentioned @ docs can use to_char proper formatter. in case to_char(pledge_bal, '$9,999.99') using format '$9,999.99' fulfills following objectives :

  • returns comma in specified position. can specify multiple commas in number format model.

  • returns decimal point, period (.) in specified position.

  • returns value leading dollar sign.

if required can check more parameters @ link mentioned.
