MYSQL:不喜欢%(从table_name中选择column_name)%

i try to find %column_name% from another table_name i see the result but he seems to ignore the %%

我试图从另一个table_name中找到%column_name%，但他似乎忽略了%%。

Why it does not work for me?

为什么它对我不起作用?

SELECT column_name FROM table_name WHERE NOT LIKE '%(SELECT column_name FROM table_name)%'

thanks, Apologies if I do not act according to the rules, this is my first question.

谢谢，如果我不按规定办事，这是我的第一个问题。

Try this:

试试这个:

SELECT column_name FROM table_name WHERE NOT LIKE (SELECT CONCAT('%', column_name, '%') FROM table_name)

You can't just include a query in a string, so put the wildcards next to the column name in a query and return that to the NOT LIKE.

您不能只在字符串中包含查询，因此将通配符放在查询的列名旁边，然后返回给不喜欢的。

SELECT column_name
FROM table_name T
WHERE NOT EXISTS ( SELECT column_name from other_table O
                   WHERE O.column_name LIKE CONCAT('%',T.column_name,'%')
                 )
