mysql - mysql : nodejs 上的语法无效

Question

nodejs新手。 我遇到了无效的语法错误。 这可能是由于试图转义字符而引起的。

let i = 0;
while(i < answered.length){
    let td = [
        connection.escape(questionnaireId),
        connection.escape(sId),
        connection.escape(questionId),
        connection.escape(answered[i]),
        connection.escape(hutk)
    ];
    values.push(td);
    i++;
}

let sql = "INSERT INTO answers (qId, sId, key, value, hutk) VALUES ?";
connection.query(sql, [values], function(err, result){
    if(err) throw err;
    console.log("Successfull Insert");
    connection.release();
});

我明白了

"errno": 1064, "sqlMessage": "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'key, value, hutk) VALUES ('18', '\'yZfXqYnvIXmLMuDAthbRr7IHtkFp5cl2ZSPCsEwY\'', ' at line 1", "sqlState": "42000", "index": 0,

"sql": "INSERT INTO answers (qId, sId, key, value, hutk) VALUES ('18', '\\'yZfXqYnvIXmLMuDAthbRr7IHtkFp5cl2ZSPCsEwY\\'', '5','\\'23@sd.lk\\'', '\\'f98a7585ce8d984a902df90263cdab5d\\'')"

Answer 1

在mysql中键入一个保留字，请尝试

 let sql = "INSERT INTO answers (qId, sId, `key`, value, hutk) VALUES ?";

您可以放置​​所有列，但这也有效
