get data from multiple tables in sql and node js

Sure! Here is an example of how you can get data from multiple tables in SQL and Node.js.

Step 1: Install necessary packages

npm install mysql

Step 2: Create a connection to the MySQL database

const mysql = require('mysql');

const connection = mysql.createConnection({
  host: 'your-hostname',
  user: 'your-username',
  password: 'your-password',
  database: 'your-database'
});

connection.connect();

Step 3: Write the SQL query to retrieve data from multiple tables

const query = `SELECT table1.column1, table2.column2
              FROM table1
              JOIN table2 ON table1.id = table2.table1_id
              WHERE condition`;

Step 4: Execute the SQL query

connection.query(query, (error, results, fields) => {
  if (error) throw error;
  console.log(results);
});

connection.end();
