A few days ago, I have asked a question on this blog. The question was – What would you like to see in the next episodes of SQL in Sixty Seconds. The poll is still active and posted over here: SQL SERVER – Poll – What would you love to see in SQL in Sixty Seconds? The contest was to suggest the next item of SQL in Sixty Seconds and vote for the your choice of subject. There have been plenty of votes to this contest, however, there were only 4 comments to this blog post. Hence, selecting a winner was very simple.

Result of Poll

It is very clear from result, most of the people would like to watch Performance Tuning subjects. I will continue to build video on this subject in future.

Contest Winner

Now is the time for the winner of the contest, who left comments on the blog. The winner is Raelyard. Here is the comment which he has left on the blog.

raelyard please reach out to me via email and I will send you the gift card.

SQL SERVER – Copy Database – SQL in Sixty Seconds #067

There are multiple reasons why a user may want to make a copy of the database. Sometimes a user wants to copy the database to the same server and sometime wants to copy the database on a different server. The important point is that DBA and Developer may want copies of their database for various purposes. I copy my database for backup purpose. However, when we hear coping database – the very first thought which comes to our mind is – Backup and Restore or Attach and Detach. Both of these processes have their own advantage and disadvantages. The matter of the fact, those methods is much efficient and recommended methods.

However, if you just want to copy your database as it is and do not want to go for advanced feature. You can just use the copy feature of the SQL Server. Here are the settings, which you can use to copy the database.

SQL SERVER – Reset SA Password – SQL in Sixty Seconds #066

It has been quite a long time since I posted SQL in Sixty Seconds Video. Here we are back with the new video.

One of the most popular question, I often receive is very similar to following:

“How do I reset the password for SA username?”

“I have forgotten the SA password, what should I do?”

“Our DBA just left the job and now noone knows how to reset the SA password. Please help.”

Solution

Honestly, it is pretty simple to reset the password for SA username. You just have to login to the system where your SQL Server is installed. Open SQL Server Management Studio and login with the help of Windows Authentication. As local system is the admin of the SQL Server, you will get access with administration privileges. Now, open the database, expand Security >> Login folder and right click over SA username. Now, it will bring up the screen where you can change the password for SA.

SQL SERVER – How to Install SQL Server 2014 – A 99 Seconds Video

Last month I presented at 3 community and 5 corporate events. Every single time I have been asked by others what is my experience with SQL Server 2014. Every single time I have told the audience that they should try this out themselves, however, the response has been very lukewarm. Everybody wants to know how SQL Server 2014 works, but no one wants to try out themselves.

Upon asking why users are not installing SQL Server 2014, pretty much the same answer I received from everyone – “The Fear of Uknown”. Everybody who have not installed SQL Server 2014 are not sure how the installation process works and what if they face any issue while installing SQL Server 2014. If you have installed an earlier version of SQL Server, installing SQL Server 2014 is very easy process.

I have created a quick video of 99 seconds where I explain how we can easily install SQL Server 2014. This is a straight forward default installation of SQL Server.

MySQL – MySQL Query Optimization and Performance Tuning – Online Video Courses

In year 2013, I had focused on MySQL along with SQL Server in database products. As I learn more and more MySQL, I quickly realized that there is no proper course or structured information for MySQL Performance Tuning.  I had decided to build a course around common MySQL Performance Problems. I have decided to build the performance tuning course in two parts. 1) MySQL Indexing for Performance and 2) MySQL Query Optimization and Performance Tuning. I had released MySQL Indexing for Performance course earlier this year and right before the end of the year 2013 the second course MySQL Query Optimization and Performance Tuning has released as well.

MySQL Query Optimization and Performance Tuning

Performance is one of the most essential aspects of any application. Everyone wants their server to perform optimally and at the best efficiency. In this course we will understand the basics of query optimization and look at practical tips and tricks for performance tuning.

Here is the broad outline of the course MySQL Query Optimization and Performance Tuning.

Introduction

In this module we go over why MySQL Performance Tuning is different from other database products. We also explained with the help of few interesting analogies where exactly we should look into when there is a problem with MySQL Performance.

Optimizing Data Access

We cannot directly jump into performance tuning before taking care of a few of the best practices around MySQL. In this module we discuss few of the best practices which one must implement various techniques explained in this course.

In this module we will see the following topics in depth:

  • Understanding Data Needs
  • Demo: Setup
  • Demo: Best Practices for Data Access
  • Demo: Why SELECT Star (*) is a Bad Idea

Understanding MySQL Query Optimization

It is very important to understand the internals of the car if we are going to participate in a car race. Similarly it is important to understand what is under MySQL Query Engine if we are going to do query optimization with MySQL.

In this module we will see the following topics in depth:

  • Execution Path of a Query
  • Client Protocols
  • Query Cache
  • Parser
  • Preprocessor
  • Query Optimizer
  • Query Optimizer Responsibilities
  • Query Optimizer Limitations
  • Query Execution Engine and Storage
  • Returning Result to Client
  • Additional Notes on Query Optimizer
  • Maximizing Query Optimizer Performance
  • Understanding Query States
  • Demo: Show Full Processlist
  • Understanding Explain Command
  • Demo: Explain Command
  • Demo: Explain Extended Command

Performance Optimization by Practical Query Tuning

In the real world we get thousands of the different scenario where the performance of our query is not upto the mark. In this module we will discuss the most common query patterns which reduces the performance of any query. In this demo oriented session we will also understand how we can tune the performance of bad query with the help of query rewrite and by implementing performance best practices.

In this module we will see the following topics in depth:

  • Demo: Index Used for SELECT clause
  • Demo: One Complex Query vs Multiple Simple Queries
  • Demo: One Complex Query vs Multiple Simple Queries – Part 2
  • Demo: One Complex Query vs Multiple Simple Queries with Index
  • Demo: Table Order in Join Clause – INNER JOIN
  • Demo: Table Order in Join Clause – OUTER JOIN
  • Demo: Most Optimal Choice – Subquery vs Exists vs Joins
  • Demo: Most Optimal Choice – Subquery vs Exists vs Joins – Part 2
  • Demo: Tuning Aggregate Function
  • Demo: Optimizing Group By Clause
  • Demo: Optimizing Paging with LIMIT Clause
  • Demo: Impact on Performance of UNION and UNION ALL
  • Demo: Index and Not Equal to Operator

Best Practices

In this final module we sum up the course in the format of Best Practices. Though the length of this module is short, it contains some really good gem inside it.

You need a valid Pluralsight subscription to watch the courses. You can sign up for free trial as well.
