    if anybodys facing a problem while ssms installation and you got a fatal error.. go to this path in your registry editor : Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager and delete the file called 'pendingfilerenameoperations'. try installing again by running as an admin..it will work.. Good Luck

    Well Done, Another Awesome Tutorial Crystal Clear and Concise. Like you stressed right away from the beginning, Null is unknow or missing value, different from zero, I cant see any circumstances null should be replaced by zero except in the division in order to secure the operation validity and return Null. Fair enough. In other operations like aggregation if not replaced with the mean, mode, or some other imputation means, Nulls values are often ignored, I mean dropped at the time of calculations or simply all the records kicked out. Again, it was an amazing tutorial, thank you a lot for the hard work. I hope to see you sooner on subqueries
