如何使用正则表达式

Question

I have 'tags' table with columns (id, link). Link possible values:

id link
1  index
2  index/index
3  index/.*

when I got index, I need to select id 1. And:

index -> 1
index/index -> 2
index/test -> 3

I use something like this:

SELECT * FROM tags WHERE 'index/test' REGEXP link LIMIT 1

But it's return me id 1, if I remove LIMIT second row will be id 3. I need just full math - only id 3.

Also for regexp, the column identifier comes first, then the search value. When I get you right, you want to get id -> 3 whenever the search term is not index or index/index. So your regex could be something like

SELECT * FROM tags WHERE link REGEXP '[^index/index|^index]$'
