Hello everybody,

I need your help to write the following procedure. I did it but dont get the out put so please help me that where I made mistake. I written the procedure just after the specification.


Write a program that computes a salesperson’s commission according to the specifications outlined below.

A particular company computes a salesperson’s weekly commission as follows:

If the salesperson sold less than or exactly equal to $ 500 in
products / services, then the salesperson’s commission rate
is 3.00

If the salesperson sold more than $ 500 but not more than $ 1,000 in products / services, then the salesperson’s commission rate
is 5.00

If the salesperson sold more than $ 1,000 in products / services,
then the salesperson’s commission rate is 10.00

To compute a salesperson’s commission, multiply the commission rate by his / her total sales.
*************** *************** *************** ***
I WRITE DOWN AS UNDER.
set serveroutput on;
set verify off;
declare
sales number := &sales;
comm_rate number(5,2);
commission number(6,2);

begin
if sales <= 500
then comm_rate := 0.03;
else if sales <= 1000
then comm_rate := 0.05;
else
comm_rate := 0.10;
end if;

commission := comm_rate * sales;
dbms_output.put _line('Employee s commission is' || commission);

End;

BUT ITS NOT WORKING . PLEASE LET ME KNOW WHERE I MADE MISTAKE.

Thank you.

What you typed in should work.

One thing to watch for in SQL*Plus is avoid putting blank lines in your anonymous PL/SQL block.

It could fool the interpreter and think that the code did not belong together.

As with all PL/SQL code, issue a slash ( / ) all by itself in the first column to execute the code.

Good luck!
