Pinal Dave

SQL Tips and Tricks

JSON, SQL Scripts, SQL Server, SQL Server 2016

I have been wanting to write about the various operators that govern to use JSON and my first shot has been with: SQL SERVER – Getting started and creating JSON using SQL Server 2016.

Pinal Dave

SQL Tips and Tricks

Notes from the Field, SQL Analysis Services, SQL Backup and Restore, SQL Server, SSAS

[Note from Pinal]: This is a new episode of Notes from the Field series. When I was new to SSAS it took me quite a while to understand the various terminology of SSAS.

I am sure if you are not familiar with SSAS the very first line of this blog “Analysis Services Perspectives are a feature that enable the designer to control which portions of the data model are exposed to the users.” may be confusing. It is alright if you are not familiar with the concept, the goal of this blog post is to understand what is perspective and how it helps user experience.

Pinal Dave

SQL Tips and Tricks

SQL Scripts, SQL Server, SQL TempDB

Before I start explaining the situation, I got into while experimenting with the SQL Server instance on my machine, let me air a word of caution – Please DONOT try this on your production environments. Unless you want to grab unwanted attention from your seniors, this is not something I would want you to ever experiment. In a recent configuration change on my local instance, I was facing an unique issue as I was standing in front of an audience for a SQL Server based session. Rarely does it happen that I get into Murphy’s law of demo not working in front of an audience because I carry multiple backups. Interestingly, this time when I tried to connect to the SQL Server using SSMS, it just refused to connect. I was completely taken aback and what happened after that is a different story about how to start SQL Server Service.
