Java & MySQL - Drop Database Example

This chapter provides an example on how to drop an existing Database using JDBC application. Before executing the following example, make sure you have the following in place −

  • To execute the following example you need to replace the username and password with your actual user name and password.

  • Your MySQL is up and running.

NOTE − This is a serious operation and you have to make a firm decision before proceeding to delete a database because everything you have in your database would be lost.

Required Steps

The following steps are required to create a new Database using JDBC application −

  • Import the packages − Requires that you include the packages containing the JDBC classes needed for database programming. Most often, using import java.sql.* will suffice.

  • Open a connection − Requires using the DriverManager.getConnection() method to create a Connection object, which represents a physical connection with a database server.

  • Deleting a database does not require database name to be in your database URL. Following example would delete STUDENTS database.

  • Execute a query − Requires using an object of type Statement for building and submitting an SQL statement to delete the database.

  • Clean up the environment − try with resources automatically closes the resources.

Sample Code

Copy and paste the following example in, compile and run as follows −

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;

public class TestApplication {
   static final String DB_URL = "jdbc:mysql://localhost/";
   static final String USER = "guest";
   static final String PASS = "guest123";

   public static void main(String[] args) {
      // Open a connection
      try(Connection conn = DriverManager.getConnection(DB_URL, USER, PASS);
         Statement stmt = conn.createStatement();
      ) {		      
         String sql = "DROP DATABASE STUDENTS";
         System.out.println("Database dropped successfully...");   	  
      } catch (SQLException e) {

Now let us compile the above example as follows −


When you run TestApplication, it produces the following result −

C:\>java TestApplication
Database dropped successfully...
