Question

I’m new to mysql and wanted to consult about using mysql for my mini game. The idea is that from a game i get two variables – one is email, and another is score.

I’m thinking of creating a table with two columns and setting email as the primary.

The question is how do I make php script replace score value for a player which tries for the second time?

For example [e-mail] scores 100 in the first try, script adds that as INSERT INTO table VALUES ($email,$score); then user tries another time, same script tries to add but gets duplicate error. Any help on script logic would be great! cheers

Answer 1

INSERT
INTO    mytable (email, score)
VALUES  ($email, $score)
ON DUPLICATE KEY
UPDATE
SET     score = $score

This requires email to be the PRIMARY KEY of mytable.
