Retrieve last inserted id with Mysql

Question

Good day,

I am willing to retrieve the id value of a freshly inserted row in Mysql.

I know there is mysqli_insert_id function, but:

1. I can't specify the table
2. Maybe there would be a risk of retrieving the wrong id, if a query is made in the meanwhile.
3. I am using node.js MySQL

I don't want to take the risk to query the highest id since there are a lot of queries, it could give me the wrong one...

(My id column is on auto-increment)

Answer 1

https://github.com/mysqljs/mysql#getting-the-id-of-an-inserted-row describes the solution perfectly well:

connection.query('INSERT INTO posts SET ?', {title: 'test'}, function(err, result, fields) {
  if (err) throw err;

  console.log(result.insertId);
});

Answer 2

var table_data =  {title: 'test'};

connection_db.query('INSERT INTO tablename SET ?', table_data , function(err, result, fields) {
  if (err) {
      // handle error
    }else{
       // Your row is inserted you can view  
      console.log(result.insertId);
    }
});
