Hi friend, These days I become little bit Lazy. The reason was my long leave from work. I visited my Hometown in Durga Puja. It was really very cheerful moment for me to meeting with parents and cousins. Please don’t ask about my last 7 Days I was suffered with Eye-Flue. It isolated me becouse I was not unable to use TV/Computer/Phone/Book, social media and SQL. After 6 days now i become OK. Session of Diwali festival also comes up. So I should wake up and write some Diwali special Query. I started my SQL Server, opened SSMS and New Query Editor new problem ….. How to generate Running Average of Last two days?
