Use cases for Query Store in SQL Server

July 18, 2018 by

Query store was introduced in SQL Server 2016. It is often referred to as a “flight data recorder” for SQL Server. Its main function is that it captures the history of executed queries as well as certain statistics and execution plans. Furthermore, the data is persistent, unlike the plan cache in which the information is cleared upon a server restart or reboot. You can customize, within Query Store, how much and how long the query store can hold the data.

Useful T-SQL techniques for development in SQL Server

July 17, 2018 by

When we’re developing solutions, we can sometimes forget useful commands we can use in T-SQL that make it convenient to remove data, eliminate objects, or carefully remove data. We look at three of these commands with a few examples of where we might consider using them in development, or in rare production cases. While they may offer us speed and convenience in some cases, we also look at some situations where they may not be the best tool to use.

It is important to understand object dependencies, particularly if you want to update an object that depends upon other objects.

Sharpen your ax

July 4, 2018 by

This is a popular story which illustrates the advantages of not just plowing away at your work, but improving your knowledge, planning, skills and preparation first to achieve a better outcome in the end

Once upon a time there were two men who lived in the same forest and decided to have a contest chopping wood.  The first man was in good physical shape and very muscular.  The second man was in good shape but smaller in statute and wiry.  They would chop wood all day and at the end of the day compare to see who had chopped the most wood.  The first man laughed to himself that there was no way this wiry little man would beat him and so they began the contest.  Every 45 minutes the second smaller man would take a break and seems to just wonder off somewhere.  The first man laughed again to himself and said “Yep there’s no way this wiry little man is going to beat me.”  This happens several times during the day.  At the end of the day the two men compare their piles of chopped wood and unbelievably enough the wiry little man has chopped twice as much wood as the more physically fit man.  He says “I don’t understand.  First I’m twice your size and twice your strength!  On top of that every 45 minutes you rolled off and took a break or a nap or something.  You must have cheated!”  The smaller man says “I didn’t cheat.  It was easy to beat you because every 45 minutes when you thought I was taking a break, I was out back sharpening my ax.” 1

When you submit a T-SQL query, you tell the SQL Server Engine what you want, but without specifying how to do it for you. Between submitting the T-SQL query to the SQL Server Database Engine and returning the query result to the end user, the SQL Server Engine will perform four internal query processing operations, to convert the query into a format that can be used by the SQL Server Storage Engine easily use to retrieve the requested data, using the processes assigned to the SQL Engine from the Operating System to work on the submitted query.

Reading the transaction log in SQL Server – from hacks to solutions

July 3, 2018 by

The SQL Server transaction log is akin to a ‘Black box’ in an airliner. It contains all of the records of transactions made against a database. This information is a proverbial goldmine for database audits, recoveries etc but it was never meant to be exposed to end users let alone visualized in an easy to read manner nor used for DBA tasks. As such, utilizing this information can be a challenge, to say the least.
