MySQL REGEXP完全相同的字符串

Question

I am trying to fetch all those results with same exact string, but the query below is returning results matching all strings having Cars, but I need only results which match exact to Cars

SELECT i.name
FROM table_name i
WHERE i.name REGEXP '[[:<:]]Cars[[:>:]]'

I thought [[:<:]] [[:>:]] would restrict the result to having only exact value

EDIT:

MY bad I didnt mention, the above is just an example, Instead of just cars there will be multiple strings, like

SELECT i.name
    FROM table_name i
    WHERE i.name REGEXP '[[:<:]]Cars[[:>:]].[[:<:]]Movies[[:>:]].[[:<:]]Camping[[:>:]]''

There will be multiple strings to match depending on the conditions. I am trying Regexp because else I will have to explicitly declare LIKE without % for all strings.

The Only reason I am using REGEXP is because I can pass my strings at once by concatenating, which is not possible using LIKE as much as I know

My table

**ColumnName**
Cars
Racing Cars
Movies
Romantic Movies

By using the above query I get all results related to cars and movies, instead I only need the exact match

Cars & Movies only

Answer 1

Why to use Regex when you want the exact match. Simply try this

SELECT i.name
FROM table_name i
WHERE i.name = 'CARS'

or

SELECT i.name
FROM table_name i
WHERE i.name like '%CARS%'

Remove the left or right wild character % as per your string and pattern

EDIT:-

So as per your edit, if you want to match only Cars and Movies then you can write like this:

SELECT i.name
FROM table_name i
WHERE i.name IN ('CARS','MOVIES')

@Deepanshu, I see that you use REGEXP, perhaps because your implementation limits you in a way that you give as a parameter to a function the whole string that will be used in a REGEXP expression. [[:<:]] and [[:>:]] match the beginning and the end of a certain matching word and not the whole string. So, you want to use ^ and $ respectively and the exact query you will use is :

SELECT i.name
FROM table_name i
WHERE i.name REGEXP '(^Cars$)|(^Movies$)|(^Camping$)'

However, since I notice a lot of people keep on using mySQL REGEXP for straight equality comparison, this is not a good practice and I suggest changing your implementation so that it uses LIKE ,equality or something similar. You could also produced dynamically a LIKE statement using a programming language.
