java Simple Java JDBC Program To Execute SQL Update Statement

Below is a sample Java JDBC program which takes database connection string as command line arguments and executes the SQL update statement.


Value to be updated in the table is passed as a command line argument.


Replace the SQL update statement in the below code with the desired update statement.

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class Run_SQL_Update {
    static Connection sqlConn = null;
    static Statement sqlStmt = null;
    static ResultSet sqlResultset = null;
    public static void main(String[] args) throws SQLException {
        try {
        } catch (ClassNotFoundException exception) {
            System.out.println("Oracle Driver Class Not found Exception: " + exception.toString());
        try {

	    String db_host=args[0];
            String db_serviceName=args[1];
            String db_username=args[2];
            String db_password=args[3];
            String jdbc_conn_string="jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST="+db_host+")(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME="+db_serviceName+")))";
	    sqlConn = DriverManager.getConnection(jdbc_conn_string, db_username, db_password);
        catch (SQLException e) {
            System.out.println("Connection Failed! Check output console");
        sqlStmt = sqlConn.createStatement();
        String var1 = args[4];
	String var2 = args[5];
	sqlResultset = sqlStmt.executeQuery("update SAMPLE_TABLE SET SAMPLE_COLUMN1='"+var1+"' where SAMPLE_COLUMN2=='"+var2+"'");

Copy paste the above code in a file having same name as the class name.


Replace the SQL update statement as per your requirement.


Compile the code:
