new query[500];
public OnGameModeInit()
{
     format(query, sizeof(query), "CREATE TABLE IF NOT EXIST `user` (`name`, `money`)");
}
public OnPlayerDisconnect(playerid)
{
     format(query, sizeof(query), "UPDATE `user` SET `money` = %d, WHERE `name` = '%e', GetPlayerMoney(playerid), GetPlayerName(playerid));
     mysql_query(Database, query);
}

try this , untested.
hope it works.
