如果字符串包含特殊字符，MYSQL搜索？

I need to search table field contains special characters. I found a solution given here something like:

我需要在搜索表字段中包含特殊字符。我找到了一个解决方案，例如：

SELECT * 
FROM `tableName` 
WHERE `columnName` LIKE "%#%" 
OR `columnName` LIKE "%$%" 
OR (etc.)

But this solution is too broad. I need to mention all the special characters. But I want something which search something like:

但这个解决方案太宽泛了。我需要提到所有特殊字符。但我想要一些搜索类似的东西：

SELECT *
FROM `tableName`
WHERE `columnName` LIKE '%[^a-zA-Z0-9]%'

That is search column which contains not only a-z, A-Z and 0-9 but some other characters also. Is it possible with MYSQL

这是搜索列，它不仅包含a-z，A-Z和0-9，还包含其他一些字符。是否可以使用MYSQL

1 个解决方案

#1

Use regexp

使用正则表达式

SELECT *
FROM `tableName`
WHERE `columnName` REGEXP '[^a-zA-Z0-9]'

This would select all the rows where the particular column contain atleast one non-alphanumeric character.

这将选择特定列包含至少一个非字母数字字符的所有行。

or

要么

REGEXP '[^[:alnum:]]'
