-- Assuming MySQL

-- Create a table to demonstrate using prepared statements
CREATE TABLE users (
    id INT PRIMARY KEY AUTO_INCREMENT,
    name VARCHAR(100),
    age INT
);

-- Using a prepared statement to insert data into the table
PREPARE insert_user FROM 'INSERT INTO users (name, age) VALUES (?, ?)';
SET @name = 'John';
SET @age = 30;
EXECUTE insert_user USING @name, @age;

-- Using a prepared statement to fetch data from the table
PREPARE select_users FROM 'SELECT * FROM users WHERE age > ?';
SET @min_age = 25;
EXECUTE select_users USING @min_age;

-- Deallocate the prepared statements to free resources
DEALLOCATE PREPARE insert_user;
DEALLOCATE PREPARE select_users;
