Java & MySQL - Create Table Example

Quiz

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

To execute the following example you can replace the username and password with your actual user name and password.
Your MySQL is up and running.

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.
Execute a query − Requires using an object of type Statement for building and submitting an SQL statement to create a table in a seleted database.
Clean up the environment − try with resources automatically closes the resources.

Sample Code

Copy and paste the following example in TestApplication.java, 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/TUTORIALSPOINT";
   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 = "CREATE TABLE REGISTRATION " +
                   "(id INTEGER not NULL, " +
                   " first VARCHAR(255), " + 
                   " last VARCHAR(255), " + 
                   " age INTEGER, " + 
                   " PRIMARY KEY ( id ))"; 

         stmt.executeUpdate(sql);
         System.out.println("Created table in given database...");   	  
      } catch (SQLException e) {
         e.printStackTrace();
      } 
   }
}

Now let us compile the above example as follows −

C:\>javac TestApplication.java
C:\>

When you run TestApplication, it produces the following result −

C:\>java TestApplication
Created table in given database...
C:\>
