如何在 mySql 中获取所有具有值的条目，然后遍历 foreach

Question

我想向不和谐 id(VERIFICATIONLINK) 发送消息，我知道如何发送带有 id 的消息，但我想知道如何循环遍历每个具有 'VERIFIED'=InProgress 的条目，获取该条目中要在 foreach 循环中使用的其他值。

下面的代码是我现在连接到mysql部分的代码

  host: config.mysqlhost,
  port: config.mysqlport,
  user: config.mysqluser,
  password: config.mysqlpassword,
  database: config.mysqldatabase,

})
connection.connect(err => {
  if(err) throw err;
  console.log("Connected to db")
})
client.connection = connection;

function continueVerification(){
  let Playervals = connection.query("SELECT * FROM " + config.mysqltable + " WHERE VERIFIED='InProgress'", console.log);
//take that above info and loop into foreach
//in the foreach, I will send a message to each entry via the 'LINKVERIFICATION' entry which is their discordID
}```

Answer 1

你这样做：

function continueVerification() {
   connection.query("SELECT * FROM " + config.mysqltable + " WHERE VERIFIED='InProgress'", (err, rows) => {
        rows.forEach(row => {
            /// our code
        })
    })
}

或者如果你想要 mysql 选择结果的 const 值，你需要使用promise，因为mysql.query 是一个callback 函数。

const Playervals = await getVerifiedUsers()

const getVerifiedUsers = () => {
    return new Promise(resolve => {
        connection.query("SELECT * FROM " + config.mysqltable + " WHERE VERIFIED='InProgress'", (err, rows) => {
            resolve(rows)
        })
    })
}
