This example is to show you how to delete or drop a table from your database. Basically we just send a "drop table" command and specify the table name to be deleted to the database.

 
package org.kodejava.example.sql;
 
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;
 
public class DropTableExample {
	public static void main(String[] args) throws Exception {
		Connection connection = null;
		try
		{
			// This is the JDBC driver class for Oracle database
			Class.forName("oracle.jdbc.driver.OracleDriver");
			
			// We use an Oracle express database for this example
			String url = "jdbc:oracle:thin:@localhost:1521:xe";
			
			// Define the username and password for connection to
			// our database.
			String username = "kodejava";
			String password = "welcome";
			
			// To delete a table from database we use the DROP TABLE
			// command and specify the table name to be dropped
			String sql = "DROP TABLE books";		
 
			// Connect to database
			connection = DriverManager.getConnection(url, username, password);
			// Create a statement
			Statement statement = connection.createStatement();
			// Execute the statement to delete the table
			statement.execute(sql);
		} catch (SQLException e) {
			e.printStackTrace();
		} finally {
			if (connection != null && !connection.isClosed()) {
				connection.close();
			}
		}
	}
}
