Create table as select on Oracle使用Jdbc创建不含行的表

CREATE TABLE new_table AS
SELECT column1, column2, ...
FROM existing_table
WHERE condition;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.Statement;

public class CreateTableExample {
    public static void main(String[] args) {
        String url = "jdbc:oracle:thin:@localhost:1521:xe";
        String username = "your_username";
        String password = "your_password";
        
        try {
            // 建立数据库连接
            Connection conn = DriverManager.getConnection(url, username, password);
            
            // 创建Statement对象
            Statement stmt = conn.createStatement();
            
            // 执行SQL语句，创建新表并插入数据
            String sql = "CREATE TABLE new_table AS SELECT column1, column2 FROM existing_table WHERE condition";
            stmt.executeUpdate(sql);
            
            // 关闭Statement和数据库连接
            stmt.close();
            conn.close();
            
            System.out.println("新表创建成功！");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
