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!
