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:>
