JDBC - Insert Records Example

This section gives a model on the best way to embed records in a table utilizing JDBC application. Prior to executing following precedent, ensure you have the accompanying set up −

  • To execute the accompanying model you can 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 a database server.

  • Execute a query: Requires utilizing an object of sort Statement for building and presenting a SQL explanation to embed records into a table.

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

Sample Code

Copy and glue the accompanying model in JDBCExample.java, incorporate 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/STUDENTS"; 

//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 a chose database..."); 

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

System.out.println("Connected database successfully..."); 

//STEP 4: Execute a query 

System.out.println("Inserting records into the table..."); 

stmt = conn.createStatement(); 

String sql = "INSERT INTO Registration " + 

"VALUES (100, 'Zara', 'Ali', 18)";

sql = "INSERT INTO Registration " + 

"VALUES (101, 'Mahnaz', 'Fatma', 25)"; 


sql = "INSERT INTO Registration " + 

"VALUES (102, 'Zaid', 'Khan', 30)"; 


sql = "INSERT INTO Registration " + 

"VALUES(103, 'Sumit', 'Mittal', 28)"; 


System.out.println("Inserted records into the table..."); 

}catch(SQLException se){ 

//Handle blunders for JDBC 


}catch(Exception e){ 

//Handle blunders for Class.forName 



//at long last square used to close resources 




}catch(SQLException se){ 

}//do nothing 




}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 delivers the accompanying outcome −

C:\>java JDBCExample 

Connecting to a chose database... 

Connected database successfully... 

Inserting records into the table... 

Inserted records into the table...
