SQL中的INT数据类型表示整数值,可以进行多种操作
SELECT column1 + column2 AS total FROM table_name;
SELECT * FROM table_name WHERE column > 50;
SELECT age, AVG(income) AS average_income FROM table_name GROUP BY age;
SELECT * FROM table_name ORDER BY income DESC;
SELECT employees.name, departments.department_name
FROM employees
JOIN departments ON employees.department_id = departments.department_id;
这些只是使用INT数据类型的一些基本操作。实际上,您可以根据需求执行更复杂的查询和操作。
