SQL SERVER – Free Online Training on .net and SQL

I around 10 Free Online Training Codes available of .NET and SQL Training from Pluralsight. I am willing to give it to someone who wants learn technology this weekend. You just have to go to my Facebook page and leave a comment explaining in one line – what course will you learn during weekend. I will send all this codes to 10 winners whom I will randomly select using Facebook.

Meanwhile do you know how can you generate Zero without using any numbers in T-SQL. My friend Madhivanan has done that and I find it very interesting.Run following T-SQL code – ‘SELECT $’. He has written many other tricks how to generate zero also on his blog.

On another note – I have published my answer for question about SELECT * vs SELECT COUNT(*) here.

    It ‘s really good.

    FYI –

    Your Hyperlink for SELECT * vs SELECT COUNT(*) here is not working.

    It is going to URL — *%20vs%20SELECT%20COUNT%28*%29

    Please update accordingly.

  • Sir, Kindly consider me for this online training for SQL. Your blog is very helpful for the ppl like us.. Thanks a lot.. :)

  • select count(*)-count(*)


  • you know what, i went to the site at the same day you posted the link for free TSQL, and happened to sign up with the sight, nice teaching. but no in-depth explanations or real time scenarios for MSBI sessions.

    do you know any site or place (including SOLIDQ, where you teach) where we can see end-to-end dwh development. like explaining starting from requirement specifications and then coming up for a solutions, rather than just learning technical. I mean total business perspective, that is real useful for students. if possible you implement the approach. at least give an insight.

    its just a suggestion.
