Mysql relating two tables with functions

Question

I have two tables one contains a list of teams, the other contains a list of schedules for these teams and score results. I want to be able to update the teams table when I insert a row into the schedules table. So for example if I have:

Teams table

Team1
Team2

.

Schedules table

team1, 3
team2, 1

what I want to be able to do is when the score fields are updated I need to update different fields in the teams table. So when I update this schedule row,

It would insert 3 into one of the rows for team1, and 1 for the team2

Also I would like to be able to calculate the difference between the scores and also insert this into the teams table.

What would be the best way to implement this?

And I would need a function in order to do the comparison of the scores right?

Thanks,

So far I thought of doing something like this.

update table teams set teams.gamesplayed = teams.gameplayed +1  /*this would add one to the games played field because they just played.*/

then for the goals scored something like

update teams set teams.gf =
(

select t.goalsscored
from schedule t, teams s
where t.teamname = s.team1name AND )

)

Answer 1

you need add ON UPDATE and ON INSERT triggers to Teams table - thats all. In trigger you can do anything you need. Of course you can create standalone function and call it from triggers.
