Im making a mysql table which will be holding my blog posts and some of their information. I want to be able to add comments the the blog posts and have them saved in mysql. My question is weather I should make a table called comments and have all the comments there have the blog post id, so I would only select the corresponding comments like this:
select from comments where id = blogpostid
Or my other idea was to put all the comments in an array, and save them in a longtext field in my blog posts table, so each row(blog post) will contain its comments.
I will accept any other ideas, but for me speed comes first.
Having a nicely normalized, separate comments table is the right thing.
With the proper indexes, it will work fine. I doubt whether there’ll ever be the kind of traffic that would justify de-normalizing the structure for speed.
