Which of these queries is better to use?

For one of my scripts I want to use a SEO friendly URL that involves something like this:

http://example.com/page-title.html

This may be a bit hard to explain so I'll give an example:

MySQL Database Structure:
id Ś seo Ścontent
1 Ś page-title Ś the page content here
2 Ś page_no_2 Śpage #2's content here
etc...

Someone goes to http://example.com/page-title.html (I have the htaccess code etc setup for all this).

The script gets the variable "page-title" from the URL and does a mysql search to find the content of that page.

I want to avoid using the id for this as it just seems cleaner to me to use something like above rather than domain.com/1/page-title.html

Now my real question is whats a better thing to do:

- Run 2 queries, the first something like:
"SELECT `id` FROM table_name WHERE seo = 'page-title' LIMIT 1"

and then get the ID and do another query:
"SELECT * FROM table_name WHERE id = '1' LIMIT 1"
To get the rest of the items from the database?

Or should I just do the first query and get all of the information I need from that?
("SELECT * FROM table_name WHERE seo = 'page-title' LIMIT 1")

Thanks! (Any other ideas on how I can optimize the above would be great too!)
