JDBC : Create Database Example

In this section you will learn how to create database using JDBC with example.

Create Database :

Database is an organized collection of data. It is the easy way of accessing ,managing and updating the data.In Our discussion we are using MYSQL database. It is Relational DBMS so we don't need to think how data is related and how to get data from database. We store the data in the form of table.
For creation of database we need to understand some terms which are important in creation of databse.

Connection: This  interface specifies connection with specific databases like: MySQL, Ms-Access, Oracle etc and java files. The SQL statements are executed within the context of this interface.

Class.forName(String driver): It loads the driver.

DriverManager  :  The DriverManager class will attempt to load the driver classes referenced in the "jdbc.drivers" system property

getConnection(String url, String userName, String password): This method establishes a connection to specified database url.

The MySQL connection URL has the following format:

  • host :The host name where MySQL server is running. Default is - the IP address of localhost.
  • port : The port number where MySQL is listening for connection. Default is 3306.
  • dbName : The name of an existing database on MySQL server. If not specified, the connection starts no current database.
  • Property : The name of a supported connection properties. "userName" and "password" are 2 most important properties.

Statement: This interface executes the SQL statement and returns the result it produces.

createStatement(): It is a method of Connection interface which returns Statement object.

executeUpdate(String table): This method of Statement interface execute sql statements(insert or delete or update) which takes the sql query of string type and returns int.

Example : In this example we are creating database, named students.

package jdbc;

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

class CreateDatabase{
public static void main(String[] args){
System.out.println("Database Creation Example!");
Connection conn = null;
Statement statement=null;
String url = "jdbc:mysql://localhost:3306/";
String driverName = "com.mysql.jdbc.Driver";
String userName = "root";
String password = "root";
conn = DriverManager.getConnection(url, userName, password);
statement = conn.createStatement();

String sql = "CREATE DATABASE students";
System.out.println("Database created successfully...");
}catch (Exception e) {

Output :

Database Creation Example!
Database created successfully...
