Question

我正在尝试将选择查询日志中的结果输出到控制台，但我得到以下内容：

代码：

connection.query("SELECT userID FROM inventories WHERE ?", invCheckedIDres, function(result) {
  message.channel.send(result)
});

错误：

C:\Users\apixe\Documents\GS Bot\node_modules\mysql\lib\protocol\Parser.js:79
        throw err; // Rethrow non-MySQL errors
        ^

TypeError: Cannot read property 'embed' of null

这里有什么我想念的吗？

Answer 1

您使用哪个模块进行sql集成？

您没有将其记录到控制台，您正在向discord发送消息。查询返回row / rows []对象，而message.send也接受字符串，而不是行。但是，我没有在您提供的代码中看到任何内容正在访问＆＃34;嵌入＆＃34;这段代码来自哪个行号？
