Hi I am trying to preview articles from blogger on a separate site, where the most recent article would show up and could link to the blog itself. I have googled enough and read about rss. I can code html, xml etc. I would really appreciate any help.

I have visited this very informative post many times, I have used mainly the scuttle design without even knowing what its name was, but in some other more controled environments I used the toxi solution. For a structured (admin controled tag solution I would go for toxi, but for a any other solution I still consider scuttle a suitable one

@Dhiraj: I don’t see any token “item” in your query – did you post the query you actually tried?

In the intersection for toxi solution i got following error : what should i do

Msg 8120, Level 16, State 1, Line 1
Column ‘item.id’ is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.

sql:
SELECT b.*
FROM tagmap bt, bookmark b, tag t
WHERE bt.tag_id = t.tag_id
AND (t.name IN (‘bookmark’, ‘webservice’, ’semweb’))
AND b.id = bt.bookmark_id
GROUP BY b.id
HAVING COUNT( b.id )=3

This is by far the best article on the world wide web that not only illustrates in clear concise language how to implement tags three different ways but also gives real world easy to follow examples and illustrations. My hat’s off to you sir. You deserve all the accolades endowed to you by your readers.

What if The primary index on the Tags table was the tag itself? So it would look like this

Tags
—-
Tag
PostID

Posts
—-
PostID
Post

QUERY
—–
SELECT * FROM Posts WHERE PostID IN (SELECT PostID FROM Tags WHERE Tag = ‘$tag1′ OR Tag = ‘$tag2′)
