Question

我在下面有一个很长的选择语句，当我运行它时，我在Node服务器上收到的错误数据太长了，但是当我将它粘贴到MySQL Workbench时它工作正常。我该如何解决此问题？

SELECT `199_roster`.`first`, `199_roster`.`last`, `199_roster`.`gender`, `199_roster`.`grade`, `199_results`.`ath_id`, `199_results`.`place`, `199_results`.`date`, `199_results`.`comment`, `199_results`.`100m Hurdles (F)`, `199_results`.`110m Hurdles (M)`, `199_results`.`100m Dash (F)`, `199_results`.`100m Dash (M)`, `199_results`.`1600m Run (F)`, `199_results`.`1600m Run (M)`, `199_results`.`4x100m Relay (F)`, `199_results`.`4x100m Relay (M)`, `199_results`.`400m Dash (F)`, `199_results`.`400m Dash (M)`, `199_results`.`200m Hurdles (F)`, `199_results`.`200m Hurdles (M)`, `199_results`.`800m Run (F)`, `199_results`.`800m Run (M)`, `199_results`.`200m Dash (F)`, `199_results`.`200m Dash (M)`, `199_results`.`4x400m Relay (F)`, `199_results`.`4x400m Relay (M)`, `199_results`.`High Jump (F)`, `199_results`.`High Jump (M)`, `199_results`.`Long Jump (F)`, `199_results`.`Long Jump (M)`, `199_results`.`Shot Put (F)`, `199_results`.`Shot Put (M)`, `199_results`.`Discus (F)`, `199_results`.`Discus (M)`, `199_results`.`Pole Vault (F)`, `199_results`.`Pole Vault (M)`, `199_results`.`3200m Run (M)`, `199_results`.`3200m Run (F)`, `199_results`.`300m Hurdles (M)`, `199_results`.`300m Hurdles (F)`, `199_results`.`4x800m Relay (M)`, `199_results`.`4x800m Relay (F)`, `199_results`.`100m Hurd.

这是我进行查询的.js文件的一部分。（通常我在客户端创建查询并动态发送，但是为了调试，我将变量设置如下）

var fullQuery = "SELECT * FROM  `199_results` INNER JOIN `199_roster` ON `199_roster`.`ath_id` = `199_results`.`ath_id` WHERE `199_results`.`date` BETWEEN '2018-04-01 00:00:01' AND '2018-05-08 23:59:59';"

    const db = require("../db"); 
    db.query(fullQuery, (err, rows, fields) => {
        if (err) { 
            res.render("results", { 
                title: "Results",
                mysqlError: err.message
                })
            return console.error('stupid error', err)
        } else {
            req.session.results = rows;
            res.send(rows)
        }
    })

如果有帮助，可以在错误消息中找到更多内容：

由于您要检索如此多的数据，所以不能只做

SELECT * FROM   FROM `199_results` INNER JOIN `199_roster` ON 
`199_roster`.`ath_id` = `199_results`.`ath_id` WHERE `199_results`.`date` 
BETWEEN '2018-04-01 00:00:01' AND '2018-05-08 23:59:59';

错误：ER_DATA_TOO_LONG：第1行的列'数据'的数据太长
