[英]MySQL: Select rows where a column is part of a given string
I search for a way to find a part of a given string in my table entries. 我在表项中寻找一种找到给定字符串一部分的方法。 The field is varchar in table.
该表中的字段为varchar。
Search for 搜索
/brands/brand/actona/kitchen-article/item/01945
/品牌/品牌/ actona /厨房文/项/ 01945
and want to find this row: 并想找到此行:
/brands/brand/actona/$
- or maybe this row -或者也许这一行
/brands/brand/actona/kitchen-$
Is there a way to solve this issue? 有办法解决这个问题吗? The problem is that the table have at least 57k entries.
问题在于该表至少具有57k条目。 I import the data from a old (too large) nginx-config file which are all permanent redirects.
我从旧的(太大)nginx-config文件中导入了数据,这些文件都是永久重定向。
Updated: What I need a roughly the opposite of "LIKE", because just a part of the string i search for is stored in table with a wildcard ($), that can match also another string that starts with the same. 更新:我需要大致上与“ LIKE”相反的内容,因为我搜索的字符串的一部分仅存储在带有通配符($)的表中,该字符串也可以匹配以该字符串开头的另一个字符串。
/brands/brand/actona/$
can match /brands/brand/actona/123
but also /brands/brand/actona/abc/def
. /brands/brand/actona/$
可以匹配/brands/brand/actona/123
,也可以匹配/brands/brand/actona/abc/def
。
So when I search for /brands/brand/actona/abc/def
or even /brands/brand/actona/abc/def/xyz
it need to match the row /brands/brand/actona/$
因此,当我搜索
/brands/brand/actona/abc/def
甚至是/brands/brand/actona/abc/def/xyz
它需要匹配/brands/brand/actona/$
I actually try to outsource 57k permanent redirects from a nginx.config file to avoid checking a 6MB config file on each request. 我实际上尝试从nginx.config文件中外包57k永久重定向,以避免在每个请求中检查6MB的配置文件。
I'm so sorry for my terrible english :( 我很抱歉我的英语不好:(
Perhaps something like 也许像
SELECT * FROM TABLE
WHERE '/brands/brand/actona/kitchen-article/item/01945'
LIKE CONCAT('%', URLCOLUMN, '%');
How about something like this? 这样的事情怎么样?
SELECT * FROM table
WHERE
column REGEXP '(/[a-zA-Z0-9-]+)+\$?'
