Question

我有WHERE的join语句和OR WHERE的多个LIKE，下面是我尝试过的内容，很遗憾，即使LIKE值无效，它也无法正常工作。 LIKE %0000%，而且我确定在给定的类似查询中没有这样的相关数据，但是下面的sql仍然返回行。任何帮助，想法将不胜感激。

SELECT `a`.`id`, `a`.`subcategory_id`, `a`.`ps_id`, `b`.`id` AS `b_id`, `b`.`ps_keyword`, `b`.`created_at`
FROM `buss_subcategory_products_services` `a`
LEFT JOIN `buss_products_services` `b` ON `b`.`id` = `a`.`ps_id`
WHERE `b`.`is_deleted` =0
AND `a`.`subcategory_id` = '11'
OR   (
`a`.`subcategory_id` = '1'
OR `a`.`subcategory_id` = '8'
OR `a`.`subcategory_id` = '5'
OR `a`.`subcategory_id` = '2'
OR `a`.`subcategory_id` = '3'
OR `a`.`subcategory_id` = '9'
OR `a`.`subcategory_id` = '4'
OR `a`.`subcategory_id` = '10'
OR `a`.`subcategory_id` = '6'
OR `a`.`subcategory_id` = '7'
 )
AND  `b`.`ps_keyword` LIKE '%xxxxxxxxxxxxxxxxxxxxxxxxxxxx%' ESCAPE '!'
ORDER BY `b`.`ps_keyword` ASC

这似乎是一个逻辑上的先发问题。

此：

WHERE 
    `b`.`is_deleted` =0
    AND `a`.`subcategory_id` = '11'
    OR  (
        `a`.`subcategory_id` = '1'
        OR `a`.`subcategory_id` = '8'
        OR `a`.`subcategory_id` = '5'
        OR `a`.`subcategory_id` = '2'
        OR `a`.`subcategory_id` = '3'
        OR `a`.`subcategory_id` = '9'
        OR `a`.`subcategory_id` = '4'
        OR `a`.`subcategory_id` = '10'
        OR `a`.`subcategory_id` = '6'
        OR `a`.`subcategory_id` = '7'
    )
    AND `b`.`ps_keyword` LIKE '%xxxxxxxxxxxxxxxxxxxxxxxxxxxx%' ESCAPE '!'

应该写成：

WHERE 
    `b`.`is_deleted` =0
    AND (
        `a`.`subcategory_id` = '11'
        OR `a`.`subcategory_id` = '1'
        OR `a`.`subcategory_id` = '8'
        OR `a`.`subcategory_id` = '5'
        OR `a`.`subcategory_id` = '2'
        OR `a`.`subcategory_id` = '3'
        OR `a`.`subcategory_id` = '9'
        OR `a`.`subcategory_id` = '4'
        OR `a`.`subcategory_id` = '10'
        OR `a`.`subcategory_id` = '6'
        OR `a`.`subcategory_id` = '7'
    )
    AND `b`.`ps_keyword` LIKE '%xxxxxxxxxxxxxxxxxxxxxxxxxxxx%' ESCAPE '!'

我建议用OR替换同一列中的多个IN条件：

WHERE
    `b`.`is_deleted` = 0
    AND `a`.`subcategory_id` IN (11, 1, 8, 5, ..., 7)
    AND `b`.`ps_keyword` LIKE '%xxxxxxxxxxxxxxxxxxxxxxxxxxxx%' ESCAPE '!'

请注意，我将值列表更改为数字而不是字符串-这些值看起来像数字，因此应将其存储和处理。

LIKE查询不适用于WHERE和多个OR WHERE
