In this example you can see how to create a table in MySQL database. We create a table called books
with the following fields, isbn
, title
, published_year
and price
. We start by creating a connection to the database and execute the create table query.
package org.kodejava.jdbc;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;
public class CreateTableExample {
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)) {
String sql = "CREATE TABLE books (" +
" isbn varchar(50) NOT NULL, " +
" title varchar(100) DEFAULT NULL, " +
" published_year int(11) DEFAULT NULL, " +
" price decimal(10,2) DEFAULT NULL, " +
" PRIMARY KEY (isbn) " +
")";
Statement statement = connection.createStatement();
statement.execute(sql);
} catch (SQLException e) {
e.printStackTrace();
}
}
}
