EXISTS 操作符
在 where 子句的 查询条件中，exists 操作符，会在子查询有返回行时，返回true；不论返回几行。
因此，子查询中的查询字段仅写1就好；标准的写法：EXISTS (SELECT 1 FROM tbl WHERE condition)
SELECT
first_name,
last_name
customer
WHERE
EXISTS (
SELECT
payment
WHERE
payment.customer_id = customer.customer_id
NO EXISTS ,与之相反，当子查询返回0行时，返回true
SELECT first_name,
last_name
FROM customer c
WHERE NOT EXISTS
(SELECT 1
FROM payment p
WHERE p.customer_id = c.customer_id
AND amount > 11 )
ORDER BY first_name,
last_name;
当子查询返回 NULL，会返回true, 也就是返回所有行。
SELECT
first_name,
last_name
customer
WHERE
EXISTS( SELECT NULL )
ORDER BY
first_name,
last_name;
与任何子查询返回的 值 匹配就 返回 true
expresion operator ANY(subquery)
表达式一般为 字段
操作符为 >,<,=,<>,>=,<=
ANY 可以与 SOME 替换
子查询 返回的 必须是 一列，
SELECT title
FROM film
WHERE length >= ANY(
SELECT MAX( length )
FROM film
INNER JOIN film_category USING(film_id)
GROUP BY category_id );
The = ANY is equivalent to IN operator.
Note that the <> ANY operator is different from NOT IN. The following expression:
x <> ANY (a,b,c)
is equivalent to
x <> a OR x <> b OR x <> c
所有子查询返回的值 匹配 则 返回 true
也就是 大于最大，小于最小
SELECT
film_id,
title,
length
WHERE
length > ALL (
SELECT
ROUND(AVG (length),2)
GROUP BY
rating
ORDER BY
length;
