Delete table example

In this example we shall show you how to delete a table. To delete a table one should perform the following steps:

  • Load the JDBC driver, using the forName(String className) API method of the Class. In this example we use the MySQL JDBC driver.
  • Create a Connection to the database. Invoke the getConnection(String url, String user, String password) API method of the DriverManager to create the connection.
  • Create a Statement, using the createStatement() API method of the Connection.
  • Invoke the executeUpdate(String sql) API method of the Statement in order to execute the DELETE statement,

as described in the code snippet below.

package com.javacodegeeks.snippets.core;

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

public class DeleteTable {
 
  public static void main(String[] args) {

    Connection connection = null;
    try {

  // Load the MySQL JDBC driver

  String driverName = "com.mysql.jdbc.Driver";

  Class.forName(driverName);


  // Create a connection to the database

  String serverName = "localhost";

  String schema = "test";

  String url = "jdbc:mysql://" + serverName +  "/" + schema;

  String username = "username";

  String password = "password";

  connection = DriverManager.getConnection(url, username, password);

  

  System.out.println("Successfully Connected to the database!");

  
    } catch (ClassNotFoundException e) {

  System.out.println("Could not find the database driver " + e.getMessage());
    } catch (SQLException e) {

  System.out.println("Could not connect to the database " + e.getMessage());
    }

    try {


  // Delete table test_table

  Statement statement = connection.createStatement();

  statement.executeUpdate("DROP TABLE test_table");


  System.out.println("Successfully dropped test_table");

    } catch (SQLException e) {

  System.out.println("Could not drop the database table " + e.getMessage());
    }

  }
}

Example Output:

Successfully Connected to the database!
Successfully dropped test_table
