MYSQL REGEXP查询关键字列

我需要一个正则表达式来获得用户只有关键字52，谁拥有的关键字52,53，但低于54不被用户表结构MYSQL REGEXP查询关键字列

CREATE TABLE `User` (
    `id` int NOT NULL AUTO_INCREMENT, 
    `first_name` varchar(100) NOT NULL, 
    `last_name` varchar(100) NOT NULL, 
    `keywords` text, 
    PRIMARY KEY (`id`) 
) ENGINE=InnoDB DEFAULT CHARSET=utf8; 

Sample record1: 100, Sam, Thompson, "50,51,52,53,54" 
Sample record2: 100, Wan, Thompson, "50,52,53" 
Sample record3: 100, Kan, Thompson, "53,52,50,54" 

50 = sports 
51 = cricket 
52 = soccer 
53 = baseball 
54 = tennis

到目前为止是这样的查询我想出了。它给记录了所有3

SELECT * FROM `User` WHERE keywords REGEXP '[[:<:]]52,53,54[[:>:]]'

尝试使用FIND_IN_SET()而不是一个复杂的正则表达式：

SELECT u.* 
FROM User 
WHERE text = '52' OR 
    (FIND_IN_SET('52', text) > 0 AND FIND_IN_SET('53', text) > 0 AND 
    FIND_IN_SET('54', text) = 0)

说明：

WHERE text = '52' -- users who have keyword 52 and only this keyword 
WHERE FIND_IN_SET('52', text) > 0 AND FIND_IN_SET('53', text) > 0 AND 
    FIND_IN_SET('54', text) = 0 
        -- users who have keywords 52 and 53 but not 54

SELECT * FROM `User` WHERE keywords RLIKE "^52$"; --only 52 
SELECT * FROM `User` WHERE keywords RLIKE "(.*(52|53)){2}" AND keywords not RLIKE "54"; -- users who have keywords 52 and 53 but not 54

编辑：备案：第二个查询应该真的是not rlike [[:<:]]54[[:>:]] ，正如在OP的最初想法中一样，为了防止匹配，比方说，154。
