SELECT description FROM products WHERE price<25;

(4) 检索customers表中编号大于3 的用户的信息，并输出行号和行标识符。

SELECT * ,@rownum:=@rownum+1 rownum FROM customers,(SELECT @rownum:=0) b WHERE customer_id>3;

(5) 检索employees表中工资大于1000的员工编号、姓名、职务和工资，并为输出列定义别名：ID,NAME,TITLE,SALARY。

SELECT e.employee_id AS ID,CONCAT (e.first_name,e.last_name) AS NAME,e.title AS TITLE,e.salary AS SALARY FROM employees e WHERE SALARY>1000;

(6) 检索employees表中，编号为2的管理者手下的所有员工的信息。

SELECT e.* FROM employees e WHERE employee_id=2;

(7) 检索employees表中，编号为2和4的员工信息。

SELECT e.* FROM employees e WHERE employee_id IN(2,4);

(8)检索用户表中last_name以’B’开头的用户的所有信息。

SELECT e.* FROM employees e WHERE SALARY <=500000 AND first_name LIKE 'F%';

1、检索顾客表中：顾客编号、姓名、出生日期。如果出生日期为NULL，则输出1970-01-01。

SELECT c.customer_id,CONCAT(c.first_name,c.last_name),IFNULL (dob,'1970-01-01') dob FROM customers c;

2、检索产品表，输出产品编号，产品名，类型编号，类型名，价格。

SELECT p.product_id,p.name,p.product_type_id,p.description,p.price FROM products p;

3、查询purchases表，统计每个产品被多少个顾客订购，共订购了多少件。

SELECT p.product_id,SUM(product_id) AS '订购数' FROM purchases p GROUP BY p.product_id;

4、查询purchases表，统计每个顾客，共购买了多少次商品，总共订购了多少件。

SELECT p.customer_id,SUM(customer_id) AS '购买商品次数' FROM purchases p GROUP BY
p.customer_id;

1、检索产品表中，每个产品的编号、名称以及所属类型的编号和名称

-- 1、检索产品表中，每个产品的编号、名称以及所属类型的编号和名称。
SELECT p.`product_id`,p.`name`,t.`product_type_id`,t.`name`
FROM products p,product_types t
WHERE p.`product_type_id` = t.`product_type_id`;

方式二

FROM products p
JOIN product_types t
ON p.`product_type_id` = t.`product_type_id`;

2、检索员工表中，每个员工的编号、姓名以及他的上司的编号、姓名，没有上司就输出空。

SELECT e1.`employee_id`,CONCAT(e1.`first_name`,e1.`last_name`),e2.`manager_id`,CONCAT(e2.`first_name`,e2.`last_name`)
FROM employees e1
LEFT JOIN employees e2
ON e1.`manager_id` = e2.`employee_id`;

3、检索每个产品的购买信息，包括：产品编号、名称、订购者编号、名称、订购数量。没有被购买过的产品也要输出。

SELECT p.`product_id`,p.`name`,c.`customer_id`,CONCAT(c.`first_name`,c.`last_name`) AS '名称',r.quantity
FROM products p
LEFT JOIN purchases r
ON p.`product_id` = r.`product_id`

ON r.`customer_id` = c.`customer_id`;

4、检索顾客表中，出生日期为NULL的顾客的编号、姓名和电话。

SELECT c.`customer_id`,CONCAT(c.`first_name`,c.`last_name`) AS '姓名',c.`phone`
FROM customers c
WHERE c.`phone` IS NULL;

– 子查询

1、基于products表，查询其价格是同类产品中价格最高或者是最低的产品的编号、产品名称。

SELECT p.`product_id` AS "MAX_id",p.`name` AS "MAX_name"
FROM products p
WHERE price IN (SELECT MAX(price) FROM products GROUP BY product_type_id);

2、基于employees表，查询手下没有下级的员工编号、姓名。

SELECT e1.`employee_id` AS "员工编号",CONCAT(e1.`first_name`,e1.`last_name`) AS "姓名"
FROM employees e1
WHERE NOT EXISTS(SELECT 1 FROM employees e2 WHERE e1.`employee_id` = e2.`manager_id`);

3、基于employees表，查询手下员工超过两名的管理人员的编号和姓名。

SELECT e1.`employee_id`,CONCAT(e1.`first_name`,e1.`last_name`)AS "姓名"
FROM employees e1
WHERE EXISTS (SELECT COUNT(1) FROM employees e2 WHERE e2.`manager_id` = e1.`employee_id` GROUP BY e2.`manager_id` HAVING COUNT(1)>=2);

《中华小厨师》单行VS爱藏：姜是老的辣，书是新的好 cicoky
《汉书·郦食其传》有曰：“王者以民为天，而民以食为天。”自古以来，吃饱饭是每一个人的基本要求，而吃好饭却是每一个人的最终追求。于是，厨师这一职业孕育而生，其渊源之久，甚至可追溯到4000年前的奴隶时代。职业本身无贵贱，但职业能力却有高低之分。所以一家餐馆生意好不好，厨师的水平决定一切，而站在所有厨师顶端的就被称之为“特级厨师”。今天要说的就是一个关于“特级厨师刘昴星”的故事。连载历程1995年第4
