【Nodejs】讀取mysql

exports.get_onwer_club_count = function (userId, callback) {
    console.log("get_onwer_club_count");
    callback = callback == null ? nop : callback;
    var sql = 'SELECT COUNT(id) FROM club WHERE club.clubowner = ' + userId + ';'
    query(sql, function (err, rows, fields) {
        if (err) {
            callback(null);
            throw err;
        } else {
            callback(rows[0]['COUNT(id)']);
        }
    })
};

Nodejs 讀取mysql 數據，要取數據條數 'COUNT(id)' 或者 ‘COUNT(*)'

如代碼中，rows[0]['keyName']，直接讀取就可以
