In the recent past, I have heard this issue, at least once or twice every month. Whenever I try to help a such client and I think I know the issue, I get something new. They said that they have applied a patch and after that they were not able to access the SQL server and it is going offline. Here is a blog post where I discuss about Unable to Start Services After Patching (sqlagent_msdb_upgrade.sql).
SQL SERVER – Fix: The Cluster Resource Could not be Deleted Since it is a Core Resource

SQL SERVER 2016 – Creating Clustered ColumnStore with InMemory OLTP Tables
I have been writing a lot of my findings with SQL Server 2016 in the recent past. This is also being something I have been investing big time keeping my session at SQLPASS coming in the October timeframe. I will be talking on a number of capabilities and enhancements around SQL Server 2016 from a performance standpoint that it is critical for me to explore some. I invest considerable time in preparation for any session and every single year going to SQLPASS has been the highlight and most of the time it is about hard work to make sure everyone attending my session gets the best of content. Also, it is a great way for me to do due diligence and homework as I prepare with real world problem statement with possible alternatives and solutions as part of my session. Let us learn about Creating Clustered ColumnStore with InMemory OLTP Tables.

SQL SERVER – Fix Error Msg 35336 Working with ColumnStore Indexes
Since my consulting have started around performance tuning, I am able to see a number of customers who want to start using the new capabilities of SQL Server for their existing application as they plan to do an upgrade of their infrastructure. In one of engagement with a bank, who was upgrading their SQL Server 2012 to SQL Server 2016, they were interested in knowing how some of the new InMemory or even usage of ColumnStore Indexes can be used. It was an interesting conversation that started which I am using as a blog here.
SQL SERVER – Performance Choice – Coding or Automation
We talk a lot about optimizing SQL with building the most efficient queries and application architectures. It’s what we enjoy doing and what we’re paid to do. We love to twiddle bits and tweak code, and can spend day after day doing this. But are we looking at the big picture? Is what we are working on the highest priority for the business or organization we work for? Are we extending our value beyond just implementing and optimizing SQL databases and applications? Can we deliver value that has a return on investment (ROI) to organizations? That ROI can be in terms of making people more productive, saving infrastructure costs, and even making trade-offs for when we should code and when we should automate. This even applies to when to use consultants like me. Can an hour of consultation with me save days or weeks of research and trial-and-error in addressing a major performance roadblock?

PowerShell – Create a User with Read Rights on a Database
I have written a number of PowerShell script in the blog and they have been used by many. Most of these scripts are there because someone wanted something different and I got about creating something simple. After I create something for a given use case, I tend to share it in the blog so that people can start using the same.
SQL SERVER – Simple Example of BCP Command Line Utility
I was recently asked if I know the fastest way to export data from SQL Server table. This was very interesting question personally, as I have not run any such tests in the past. However, everytime when I had to export data, I have used in past BCP command line utility and I have found it does a pretty good job.
