mysql - 混淆 mysql select 结果与 LIKE 和多个零 (%00%)

Question

我创建了一个搜索查询来在表中搜索多个字段中的字符串。它适用于每个字符串，除非该字符串仅包含一个或多个零，例如:%000% 返回包含 2 个或更少零的行。

搜索字段:

`par_partno` varchar(20) utf8_general_ci
`par_group_id` varchar(16) utf8_bin
`par_desc` text utf8_general_ci
`par_details` text utf8_general_ci

我已经尝试将 par_partno 转换为 char CAST(par_partno AS CHAR) 但结果是相同的。

查询:

select `par_id`, `pag_id`, `par_partno`, `par_group_id`,`par_cond`, `par_desc`,`par_price`,
`par_stock`, `par_feature`, `par_weight`, `par_details`, `par_related`, `par_meta`,
`par_picture`, `par_lastmod`
from `parts`
where concat(`par_partno`, `par_group_id`, `par_desc`, `par_details`) like "%000%"
order by `par_group_id` asc 

错误结果:

[

Answer 1

我可能会误解你的问题，但检查的字符串不是例如的串联

par_partno":"7101263500","par_group_id":"01-00-12"

所以

710126350001-00-12

其中包含“000”子字符串。
