Re: table structure question

I would do it a little bit different:

1. I would add ID's for each of the tables.
2. I would split teams in 2 tables; the captain stuff would be in a
separate table (captain_team let's say), simply because I would have
different players as captains in different games. If you keep the
structure as it is now, you'll have a lot of duplication.
So, I would do it like this:

teams
---
IDteam | name | ...

teams_captain
---
IDteam| IDplayer| Game (this could be date format)


players
----
IDplayer |...

Then, if you want to see the players who were captains for a given team,
you can write smth. like:

select distinct p.lname from players p, teams_captain t, teams tt where
p.IDplayer=t.IDplayer and t.IDteam=tt.IDteam and tt.name like 'Real
Madrid'

Check also the normalization forms of a database, which you can find in
any database book, simply because you'll have complications if you record
more than 1 season and some teams can move in different leagues.

Hope this helps.
