heroku node.js錯誤

Question

代碼因此，我決定使用heroku和node.js制作一個不一致的機器人，但我不斷收到此錯誤：

錯誤：“ DUPLICATE”處或附近的語法錯誤

我嘗試調試，但沒有結果，所以是的...我需要幫助。 我用JavaScript東西將什么發送到sql postgresql數據庫：

'INSERT INTO points (Roblox_name, Points) VALUES (' + name + ', ' + amount + ') ON DUPLICATE KEY UPDATE Points=VALUES(' + amount + ')'

示例{數量= 322，名稱=喬治}

編輯：原始應用程序日志[值（'+數量+'）'更改為'+數量]：

Answer 1

您無需在語句的此部分中重新指定值Points=Values(' + amount + ')'

相反，它可以是Points = amount 。 也許你會需要CAST或CONVERT amount為整數值，但應該是它。

Answer 2

如果Roblox_name和Points是字符串，則必須在' values '中設置value

"INSERT INTO points (Roblox_name, Points) VALUES ('" + name + "','" + amount + "')
ON DUPLICATE KEY UPDATE Points=VALUES('" + amount + "')"

你應該用

if(err !== null){
    console.error(err);
    return;
}

代替

if (err) throw err;
