mysql - 从 js 运行时插入错误，xampp shell 使用相同的 sql 工作正常

Question

这是我尝试运行的sql，当我使用xampp时，我能够得到插入表的响应。但如果我将 sql 传递到查询函数中，我无法将查询插入到我的表中。我收到以下错误:

START TRANSACTION;
INSERT INTO address_tbl (address_ln_1, address_ln_2, address_town, address_county, address_postcode) VALUES ('place', '', 'Town', 'county', 'postcode');
SELECT LAST_INSERT_ID();
COMMIT;

使用js:

var query= function (sql){
    return new Promise(resolve => {
        con.query(sql, (err, result) => {
            if(err) throw err;
                resolve(result);
        });
    });
}

错误:

C:\node_modules\mysql\lib\protocol\Parser.js:437
      throw err; // Rethrow non-MySQL errors
      ^

Answer 1

因此，只需阅读错误消息并与上面的(工作)查询进行比较即可:

Working:         INSERT INTO address_tbl (address_ln_1, address_ln_2, address_town, address_county, address_postcode) VALUES ('place', '', 'Town', 'county', 'postcode');

Error Message:  'INSERT INTO address_tbl (address_ln_1, address_ln_2, address_town, address_count'

您缺少表格插入的一些参数。我会看看这是为什么。
