It's not 'referring', you've cut and paste 90% of the text from BOL. Without even providing a reference.

If you copy random chunks of your article and put the whole phrase in Google, result number 1 is MSDN with an article with the same name as your section heading and the exact phrase in the MSDN article.

e.g. "Common table expression (CTE) can be thought of as a temporary result", "A recursive CTE is one in which an initial CTE", "following example first creates a synonym for the base object"

The exact word-for-word phrases are returned on MSDN. If you use word-for-word without putting it in quotes and providing where the original is located it is plagiarism, you would be thrown out of a University, fired from a Newspaper, never be able to work in the field again. To do it not once but as an entire 'article' is extreme.

And you've still not provided the references you used:
