How to create a Calculated Column in MySQL? -


i'm working on sports bookkeeping project , create calculated field. there 4 values of interest: risk: how risked odds: float value (e.g 2.5) result: 'w', 'l', 'd' win, lose or draw returned: calculated field

the returned value can determined follows:

if (result == 'w'){     $returned = $risked*odds } else if ($result == 'l') {     $returned = $risked*-1 } else {     $returned = 0 }

but i'm @ loss how create calculated column.

supposing have table named tablename fields named risked, odds, , result, query select 3 fields plus calculated one, called returned:

select      result,     risked,     odds,      case result         when 'w' risked*odds         when 'l' risked*-1         else 0         end returned tablename;

it's not column per se, can create view select.
