Here’s an example to show you how to insert a record into table via JDBC statement. To issue a insert statement, calls the Statement.executeUpdate() method like this :


Statement statement = dbConnection.createStatement();
// execute the insert SQL stetement
statement.executeUpdate(insertTableSQL);

Full example…


package com.mkyong.jdbc;

import java.sql.DriverManager;
import java.sql.Connection;
import java.sql.SQLException;
import java.sql.Statement;
import java.text.DateFormat;
import java.text.SimpleDateFormat;

public class JDBCStatementInsertExample {

	private static final String DB_DRIVER = "oracle.jdbc.driver.OracleDriver";
	private static final String DB_CONNECTION = "jdbc:oracle:thin:@localhost:1521:MKYONG";
	private static final String DB_USER = "user";
	private static final String DB_PASSWORD = "password";
	private static final DateFormat dateFormat = new SimpleDateFormat(
			"yyyy/MM/dd HH:mm:ss");

	public static void main(String[] argv) {

		try {

			insertRecordIntoDbUserTable();

		} catch (SQLException e) {

			System.out.println(e.getMessage());

		}

	}

	private static void insertRecordIntoDbUserTable() throws SQLException {

		Connection dbConnection = null;
		Statement statement = null;

		String insertTableSQL = "INSERT INTO DBUSER"
				+ "(USER_ID, USERNAME, CREATED_BY, CREATED_DATE) " + "VALUES"
				+ "(1,'mkyong','system', " + "to_date('"
				+ getCurrentTimeStamp() + "', 'yyyy/mm/dd hh24:mi:ss'))";

		try {
			dbConnection = getDBConnection();
			statement = dbConnection.createStatement();

			System.out.println(insertTableSQL);

			// execute insert SQL stetement
			statement.executeUpdate(insertTableSQL);

			System.out.println("Record is inserted into DBUSER table!");

		} catch (SQLException e) {

			System.out.println(e.getMessage());

		} finally {

			if (statement != null) {
				statement.close();
			}

			if (dbConnection != null) {
				dbConnection.close();
			}

		}

	}

	private static Connection getDBConnection() {

		Connection dbConnection = null;

		try {

			Class.forName(DB_DRIVER);

		} catch (ClassNotFoundException e) {

			System.out.println(e.getMessage());

		}

		try {

			dbConnection = DriverManager.getConnection(
                               DB_CONNECTION, DB_USER,DB_PASSWORD);
			return dbConnection;

		} catch (SQLException e) {

			System.out.println(e.getMessage());

		}

		return dbConnection;

	}

	private static String getCurrentTimeStamp() {

		java.util.Date today = new java.util.Date();
		return dateFormat.format(today.getTime());

	}

}

Result

A record is inserted into a table named “DBUSER”.


INSERT INTO DBUSER(USER_ID, USERNAME, CREATED_BY, CREATED_DATE) 
VALUES(1,'mkyong','system', to_date('2011/04/04 13:59:03', 'yyyy/mm/dd hh24:mi:ss'))
Record is inserted into DBUSER table!
