Node.js MySQL Drop Table

The DROP TABLE command in MySQL is used to permanently delete an existing table from the database. Once a table is dropped, all the data stored within it is also removed.

In this guide, we’ll learn how to drop a table named employee2 using Node.js and the MySQL module.

Step 1: Create a JavaScript File

First, create a new file named delete.js inside your DBexample folder. Then, add the following code to it:

var mysql = require('mysql');  
var con = mysql.createConnection({  
  host: "localhost",  
  user: "root",  
  password: "12345",  
  database: "updategadh"  
});  

con.connect(function(err) {  
  if (err) throw err;  
  var sql = "DROP TABLE employee2";  
  con.query(sql, function (err, result) {  
    if (err) throw err;  
    console.log("Table deleted");  
  });  
});  

Step 2: Run the Script

Once you’ve saved the file, open your terminal or command prompt, navigate to the DBexample directory, and run the following command:

node delete.js

If everything is set up correctly, you’ll see the message:

Table deleted

Step 3: Verify the Deletion
