Node-MySQL 无法插入 TIME

Question

我正在尝试在 Express.JS 中构建一个 API，后台有一个 MySQL-Server 运行。其中一个 table 包含类型为 TIME 的列。但是，当尝试插入 table 时，我得到 {code: 'ER_PARSE_ERROR', errno: 1064, sqlState: '42000'}

使用单个 ?，消息是：

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 \'\'23:00:41\'\' at line 1

使用双 ??，消息是：

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 \'`23:00:41`\' at line 1

实际的代码行是这样的：

let query = "INSERT INTO Zeiterfassung (Break_Start) VALUES ? ";
let data = Break_Start; //Break_Start is a string like "23:40:39"
dbConn.query(query, data, (err, rows) => {...});

MySQL-版本：8.0.22-0ubuntu0.20.04.2

节点版本：v10.19.0

Answer 1

如果你有一个字符串参数，那么你需要用括号把?括起来：

let query = "INSERT INTO Zeiterfassung (Break_Start) VALUES (?)";
dbConn.query(query, [ Break_Start ], function(err, rows) => {...});

带有单个 ? 且不带括号的语法旨在传递对象。
