Question

我正在使用以下代码：

//Handles every game and their attributes
function handleGames(){
    sql.query('SELECT id FROM games', function (err, rows){
        if(err){
            console.log(String(err).error.bgWhite);
        } else {
            for(var i = 0; i < rows.length; i++) {
            /** ["id"]
                ["starttime"]
                ["status"]
                ["ct_name"]
                ["ct_avatar"]
                ["ct_steamid"]
                ["ct_bet"]
                ["t_name"]
                ["t_avatar"]
                ["t_steamid"]
                ["t_bet"]           **/

                var timeNow = new Date().getTime();
                //console.log(String(timeNow).info.bgWhite);

                //Game Expiration
                //0 = Open | 4 = Expired | 5 = Generic Error

                //Generic error --> Expired
                if(rows[i]["status"] == 5){
                    sql.query('UPDATE games SET status = 4 WHERE id = "' + rows[i]["id"] + '"', function (err, rows){
                        if(err) console.log(String(err).error.bgWhite);
                        console.log(("Updating status for game " + rows[i]["id"] + " to 4").info.bgWhite);
                    });
                }

                //Gamestatus set to expired if game has lasted 5m (300s)
                if(((rows[i]["starttime"] + 300) >= timeNow) && (rows[i]["status"] == 0)){
                    sql.query('UPDATE games SET status = 4 WHERE id = "' + rows[i]["id"] + '"', function (err, rows){
                        if(err) console.log(String(err).error.bgWhite);
                    });
                }
            };
        }
    });
}

使用以下数据：

该程序是为Node编写的，应该会改变任何持续5分钟（300s）的游戏的状态，但是我无法使用键进行导航。 游戏状态未更新。

Answer 1

所以((new Date()).getTime()-starttime)/1000会给你持续时间，以秒为单位你能在任何在线javascript编辑器中发布代码，如plunker！你在这？

INSERT INTO `games` (`id`, `starttime`, `status`, `ct_name`, `ct_avatar`, `ct_steamid`, `ct_bet`, `t_name`, `t_avatar`, `t_steamid`, `t_bet`) VALUES 
(3, 1461862619, 0, 'Robinlemon > CSGOVoid.net', 'steamcdn-a.akamaihd.net/…', 76561198065346589, 3, 'Yuuta', 'cdn.akamai.steamstatic.com/…', 76561198052096214, 3);

这是你的转储sql！这是插入一个id（带AUTO_INCREMENT）3的实体!! 所以对于下一个插入，AUTO_INCREMENT将是4 !!!

如果你想改变你删除表中的行和重置AUTO_INCREMENT计数器

ALTER TABLE tablename AUTO_INCREMENT = 1
