Question

I am writing a function to get overall score in SQL

What I have is;

out of 20 points I got 12.4 points

so if I transform that, to take percentage over 100% how would I do it?

Thanx,
Adnan

Answer 1

Presuming you mean “function” as in stored procedure, it would look like this in Oracle:

create or replace function pct
    (p_score in number
     , p_total in number)
    return number
    deterministic
is
begin
    return p_score * (100/p_total);
end;

Different flavours of database have different specifications for writing stored procedures.
