JDBC - Create Database Example


This instructional exercise gives a precedent on the most proficient method to make a Database utilizing JDBC application. Prior to executing the accompanying precedent, ensure you have the accompanying set up −

  • You ought to have administrator benefit to make a database in the given pattern. To execute the accompanying model, you have to supplant the username and password with your genuine client name and password.

  • Your MySQL or whatever database you are utilizing, is up and running.

Required Steps

The following advances are required to make another Database utilizing JDBC application −

  • Import the packages: Requires that you incorporate the bundles containing the JDBC classes required for database programming. Regularly, utilizing import java.sql.* will suffice.

  • Register the JDBC driver: Requires that you introduce a driver so you can open a correspondences channel with the database.

  • Open a connection: Requires utilizing the DriverManager.getConnection() strategy to make a Connection object, which speaks to a physical association with the database server.

    To make another database, you need not give any database name while getting ready database URL as referenced in the beneath example.

  • Execute a query: Requires utilizing an object of sort Statement for building and presenting a SQL articulation to the database.

  • Clean up the earth . Requires unequivocally shutting all database assets as opposed to depending on the JVM's waste collection.

Sample Code

Copy and past the accompanying model in JDBCExample.java, aggregate and keep running as pursues −

//STEP 1. Import required packages 

import java.sql.*; 

public class JDBCExample { 

//JDBC driver name and database URL 

static final String JDBC_DRIVER = "com.mysql.jdbc.Driver"; 

static final String DB_URL = "jdbc:mysql://localhost/";

//Database credentials 

static final String USER = "username"; 

static final String PASS = "password"; 

public static void main(String[] args) { 

Connection conn = null; 

Statement stmt = null; 


//STEP 2: Register JDBC driver 


//STEP 3: Open a connection 

System.out.println("Connecting to database..."); 

conn = DriverManager.getConnection(DB_URL, USER, PASS); 

//STEP 4: Execute a query 

System.out.println("Creating database..."); 

stmt = conn.createStatement(); 



System.out.println("Database made successfully..."); 

}catch(SQLException se){ 

//Handle mistakes for JDBC 

}catch(Exception e){ 

//Handle blunders for Class.forName 



//at long last square used to close resources 




}catch(SQLException se2){ 

}//nothing we can do 




}catch(SQLException se){ 


}//end at long last try 

}//end try 


}//end main 

}//end JDBCExample

Now, let us order the above precedent as pursues −

C:\>javac JDBCExample.java 


When you run JDBCExample, it creates the accompanying outcome −

C:\>java JDBCExample 

Connecting to database... 

Creating database... 

Database made successfully...
