Hi Pinal,
I liked the blog SQL Joes 2 Pros Development Series – Ranking Functions – RANK( ), DENSE_RANK( ), and ROW_NUMBER( ), because in this blog these functions are explained well. Earlier while finding rank I was using temporary table and now I am using RANK() function.

Best Regards,
S Kumar

I’m not sure I have a favorite article, I like a lot of them. I really enjoyed learning about all the things you can do with Rank, Row_number and NTile. I didn’t know about NTile before this. I think these would simply some of our old reporting code where we pretty much do this, but the long way. I’d like to update the code using these methods

Option C) is wrong. The idea of the Identity value is an incremental feature (That is possible in int, bigint, smallint, tinyint,decimal or numeric data types). With a VARCHAR datatype is not possible to do that..

Ans : Identity value can be of datatype VARCHAR

Identity column must be of data type int, bigint, smallint, tinyint, or decimal or numeric.

Identity is possible on only following datatype int, bigint, smallint, tinyint, or decimal or numeric.
Hence answer c) Identity value can be of datatype VARCHAR is wrong
