Hello Everyone. My intention of having this site is to have one repository location for my SQL Server Learning's. Most of the information here is already available on Web but I want to have it in one global location, so I can reference whenever I need . I would be more than happy, if you find anything on this blog useful. Also, Please use your own caution when running any code on your systems.Thank you for visiting.
