Java如何在数据库中创建表？
在此示例中，您可以看到如何在MySQL数据库中创建表。我们创建了一个称为表books具有以下字段，isbn，title，published_year和price。我们首先创建与数据库的连接，然后执行创建表查询。
package org.nhooo.example.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/nhooo";
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();
}
}
