SQL Tips and Tricks

ColumnStore Index, SQL Extended Events, SQL Index, SQL Server

In the recent past, I have written a number of posts around ColumnStore Index and how they function. Some of the nuances of working with ColumnStore Indexes are available in this blog for reference. I have also written a few posts around Extended Events. One of my DBA friends pinged me to check if there were any way to use Profiler to see how ColumnStore Indexes worked. Obviously, there was nothing much of help I could offer because there were actually none in reality.

SQL Interview Questions and Answers

SQL Scripts, SQL Server, SQL Stored Procedure

I have kept busy with SQL Consultancy now a days. Just the other day, while doing performance tuning exercise we had made major changes in the data stored in one of the main tables. The impact was so huge that we realized that it will impact how the SQL Server engine is building execution plans for that table. This brought up a question among us that – How to Recompile Stored Procedure for Specific Table? Well, this time the question was really not asked in the interview, but I really feel that it will be nice to address it here in this series.

SQL SERVER – Introduction to SQL Azure Database Throttling

Pinal Dave

SQL Tips and Tricks

SQL Azure, SQL Scripts, SQL Server

In standalone versions of SQL Server, if your SQL Server receives more concurrent requests than it can service simultaneously, it will queue the requests for later processing (subject to certain limits—generally available memory on the box). For example, if you have the max worker thread configuration option set to 100 and there are already 100 queries submitted to the server than any new requests are simply queued until one of the worker threads completes and can pick up the request. Except in fatal circumstances where DBA intervention is required this will allow all of the requests to eventually complete (or potentially timeout, if the client specified this setting). Let us understand about SQL Azure Database Throttling.

SQL Tips and Tricks

Notes from the Field, SQL DateTime, SQL Function, SQL Scripts, SQL Server

SQL Server 2016 is around the corner. We already have SQL Server 2016 RC0 released and many of us have started to test out various aspects of the same. For many years users have created temporary tables as well as used cross apply functions to split a large string and make it a table. I think every single time when I was assigned this task, I disliked it as the methods I used never made me happy. Well, the situation is now changed now with STRING_SPLIT function in SQL Server 2016.

In this episode of the Notes from the Field series database expert Kathi Kellenberger explains about easy and amazing functions of SQL Server. Kathi is an amazing instructor, she was the SQL author I have read in my early career. Today she brings a very new topic for database experts. Read the experience of Kathi in her own words.
