Question

I am storing pages for websites in a ‘pages’ database table, they are referenced by their path (i.e. ‘articles/my-first-blog-post’), I need to select all the children of a particular page, but without selecting grandchildren.

So if I run:

SELECT * FROM pages WHERE path LIKE 'articles%'

I’ll get pages with the following paths:

articles/one
articles/two
articles/two/more
articles/three
articles/three/more/even-more

I need to filter them (in the query) to just:

articles/one
articles/two
articles/three

Is there anyway to do something like:

SELECT * FROM pages WHERE path LIKE 'articles%' AND path NOT LIKE 'articles%/%'

Any ideas? Cheers.

You can use regular expressions for that. The keyword REGEXP works both for mysql and sqlite:

... WHERE path REGEXP '^articles/[^/]+'
