Mysql Query: find all the posts along with x ascending which has nggallery id in post_content column

I have a table wp_posts with a column post_content. some of the post entry has [nggallery id=x] inside post_content column. I want to find all the posts along with x (gallery id no, it is different for different gal开发者_如何学Golery) ascending which has nggallery id in post_content column. How can I do it?

You can try something like this:

SELECT * FROM wp_posts WHERE post_content LIKE '%[nggallery id=%';

Try this, just don't ask :)

select
left(substring(post_content,locate('[nggallery id=',post_content)+14,5),locate(']',substring(post_content,locate('[nggallery id=',post_content)+14,5))-1)  as NumValue, post_content
from wp_posts
WHERE post_content LIKE "[nggallery id=%]"
ORDER BY 1

Maybe he meant this:

SELECT * FROM wp_posts WHERE post_content LIKE "[nggallery id=%]"
