Re: Why doesn't this query work? Puzzle to hard for me to crack

These queries are identical!

I'm guessing your query works because there is only one player named
Robert.  If there were more than one Robert; the query will likely also
produce incorrect results.

IAC, try adding "GROUP BY players.player_id".
