如何使用node.js在数组中插入sql查询数据
我想在 mysql 数据库中插入数据，也在使用 node.js 的数组中插入数据，请给出正确的解决方案。

var conn = mysql.createConnection({
      host: "localhost",
      user: "root",
      password: "root@123",
      database: "abc"

});
conn.connect(function(err) {
  if (err) throw err;
  console.log("Connected!");
});

var temp = [1, 2];
sql =
  "INSERT INTO  student(`name`, `email`) VALUES (?) ";

conn.query(sql, [temp], function (err, result) {
    console.log(temp);
     if (err) throw err;
     conn.end();
});```

嘿，请像这样更改您的代码...

var conn = mysql.createConnection({
      host: "localhost",
      user: "root",
      password: "root@123",
      database: "abc"
});
conn.connect(function(err) {
  if (err) throw err;
  console.log("Connected!");
});

var temp = [1, 2];
var sql =
  "INSERT INTO  student(`name`, `email`) VALUES (?,?) ";

conn.query(sql, temp, function (err, result) {
    console.log(temp);
     if (err) throw err;
     conn.end();
});
