Чтобы написать статью в блоге об извлечении информации о студентах и ​​курсах с примерами кода, вы можете использовать различные языки программирования и платформы. Вот несколько методов на разных языках:

1. SQL (язык структурированных запросов):

   SELECT
   student.id AS student_id,
   student.full_name AS student_name,
   course.id AS course_id
   FROM
   student
   JOIN
   course ON student.course_id = course.id;

2. Python с SQLAlchemy (набор инструментов Python SQL и объектно-реляционный преобразователь):

   from sqlalchemy import create_engine, Column, Integer, String
   from sqlalchemy.orm import sessionmaker
   from sqlalchemy.ext.declarative import declarative_base
   # Define the database schema
   Base = declarative_base()
   class Student(Base):
   __tablename__ = 'student'
   id = Column(Integer, primary_key=True)
   full_name = Column(String)
   course_id = Column(Integer)
   class Course(Base):
   __tablename__ = 'course'
   id = Column(Integer, primary_key=True)
   # Create a session and query the data
   engine = create_engine('your_database_connection_string')
   Session = sessionmaker(bind=engine)
   session = Session()
   result = session.query(Student.id.label('student_id'), Student.full_name.label('student_name'), Course.id.label('course_id')) \
   .join(Course, Student.course_id == Course.id) \
   .all()
   # Process the result
   for row in result:
   student_id = row.student_id
   student_name = row.student_name
   course_id = row.course_id
   # Do something with the data
   session.close()

3. Java с JDBC (подключение к базе данных Java):

   import java.sql.*;
   public class Main {
   public static void main(String[] args) {
       String url = "jdbc:your_database_connection_url";
       String username = "your_username";
       String password = "your_password";
       try (Connection conn = DriverManager.getConnection(url, username, password);
            Statement stmt = conn.createStatement()) {
           String query = "SELECT student.id AS student_id, student.full_name AS student_name, course.id AS course_id " +
                   "FROM student " +
                   "JOIN course ON student.course_id = course.id";
           ResultSet rs = stmt.executeQuery(query);
           while (rs.next()) {
               int studentId = rs.getInt("student_id");
               String studentName = rs.getString("student_name");
               int courseId = rs.getInt("course_id");
               // Do something with the data
           }
       } catch (SQLException e) {
           e.printStackTrace();
       }
   }
   }

4. Ruby с ActiveRecord (объектно-реляционное сопоставление Ruby):

   require 'active_record'
   # Configure the database connection
   ActiveRecord::Base.establish_connection(
   adapter: 'your_database_adapter',
   database: 'your_database_name',
   username: 'your_username',
   password: 'your_password'
   )
   # Define the models
   class Student < ActiveRecord::Base
   belongs_to :course
   end
   class Course < ActiveRecord::Base
   has_many :students
   end
   # Query the data
   results = Student.select("student.id AS student_id, student.full_name AS student_name, course.id AS course_id")
                .joins(:course)
   # Process the result
   results.each do |row|
   student_id = row.student_id
   student_name = row.student_name
   course_id = row.course_id
   # Do something with the data
   end
