Combining values from two separate tables

[benjam]

I have a chess script and I would like to add the total wins, draws, and losses collected in one instance (table) to the wins, draws, and losses collected in another instance (table).

For instance:

table 1 is like:
player
p_id
p_username
p_wins
p_draws
P_losses

and table 2 is like:
wc2_player
p_id
p_username
p_wins
P_draws
p_losses

I would like to add the wins from `player` into `wc2_player`, but only if the value for p_username is the same.

Can I do this in one query?  Both tables are in the same DB.

Try the following (UNTESTED, so back up your DB!)
[code]
UPDATE wc2_player INNER JOIN player USING p_username
SET wc2_player.p_wins += player.p_wins
[/code]
