Question

I am writing a database for a quiz module. There are two tables one for teams and one for submitted data. The teams are able to play a joker in one round only and get their scores doubled for that round.

So the teams table has a filed fldJoker that is an int and can be 1 to 8.

The data table contains a teamid (who submitted it), plus a round number and a score.

When I calculate the total scores, I want to double the scores in the round that had the joker played, and this is the sticking point for me.

Could anyone give me any pointers please?

Answer 1

You want to do something like this:

select teamid, sum(score * if(fldJoker = round, 2, 1)) ...
