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, 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 −



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...
