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:>
