8. 查询数据：

SELECT column1, column2, ... FROM table_name WHERE condition ORDER BY column_name ASC/DESC;

9. 连接表：

10. 聚合函数：

SELECT COUNT(column_name), SUM(column_name), AVG(column_name), MIN(column_name), MAX(column_name) FROM table_name;

11. 子查询：

SELECT column_name(s) FROM table_name WHERE column_name OPERATOR (SELECT column_name FROM table_name WHERE condition);

12. 分组：

SELECT column_name(s) FROM table_name GROUP BY column_name(s);

13. 过滤分组：

SELECT column_name(s) FROM table_name WHERE condition GROUP BY column_name(s);
