In this example you’ll learn how to create a program to insert data into a database table. To insert a data we need to get connected to a database. After a connection is obtained you can create a java.sql.Statement object from it, and using this object we can execute some query strings.
package org.kodejava.jdbc;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;
public class InsertStatementExample {
private static final String URL = "jdbc:mysql://localhost/kodejava";
private static final String USERNAME = "root";
private static final String PASSWORD = "";
public static void main(String[] args) {
try (Connection connection =
DriverManager.getConnection(URL, USERNAME, PASSWORD)) {
// Create a statement object.
Statement stmt = connection.createStatement();
String sql = "INSERT INTO books (isbn, title, published_year) " +
"VALUES ('9781617291999', 'Java 8 in Action', 2015)";
// Call an execute method in the statement object
// and pass the query.
stmt.execute(sql);
} catch (SQLException e) {
e.printStackTrace();
}
}
}
Below is the script from creating the books table.
CREATE TABLE `books` (
`isbn` varchar(50) COLLATE utf8_unicode_ci NOT NULL,
`title` varchar(100) COLLATE utf8_unicode_ci DEFAULT NULL,
`published_year` int(11) DEFAULT NULL,
`price` decimal(10,2) DEFAULT NULL,
PRIMARY KEY (`isbn`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
