Optimizing SQL Server index strategies

July 2, 2019 by

Index strategies overview

This article is about techniques for optimizing the SQL Server indexes strategy. It is an appendix of the SQL index overview and strategy article in which I covered different areas like what indexes actually do, how to create them, and I briefly mentioned some index design guidelines. Furthermore, I also presented an example of how to design them by tuning and optimizing queries, so I’ve really tried to cover all but there is always more when it comes to SQL Server indexes.

How to markup, annotate content like a boss

December 5, 2018 by

Overview

As a writer and content creator, I often use annotation and drawing markup tools to add value to the content I’m creating. You might not think of it as a big deal, but the human brain processes visuals 60,000 times faster than text. Is it true? Probably not. There’s no scientific evidence to back up this figure. However, it’s a fact that humans process visual data better. Therefore, I always try to deliver helpful, value-added content with a lot of visuals suitable for easy reading and understanding.

A SQL index is used to retrieve data from a database very fast. Indexing a table or view is, without a doubt, one of the best ways to improve the performance of queries and applications.

A SQL index is a quick lookup table for finding records users need to search frequently. An index is small, fast, and optimized for quick lookups. It is very useful for connecting the relational tables and searching large tables.

SQL Join introduction and overview

November 15, 2018 by

A SQL Join clause is put within a Select statement and at the end, it’s given a join condition, which tells the database how to fetch your data. The column specified within the join condition must be preceded by a table name if the column name is the same in both tables. When a column is preceded with a table name, it’s known as a qualified column.

How to collect performance and system information in SQL Server

August 16, 2018 by

In this article, we’re going to through many of the tools we can use for monitoring SQL Server. SQL Server is chock-full of lots of good reports that allows a DBA to quickly spot whether there is any current performance bottleneck on the SQL Server. Many of these sit on top of DMVs but they give us a visually interactive way to look and work with the data. We’re going to start with SQL Server Performance Dashboard Reports.

Dashboard Reports

Let’s jump into SQL Server Management Studio (SSMS) and the first thing we’re going to take you through out-of-the-box dashboard reports of all levels. They can be found by right-clicking the SQL Server instance in Object Explorer, and from the context menu, you’ll find Reports > Standard Reports:

How to implement error handling in SQL Server

June 15, 2018 by

Error handling overview

Error handling in SQL Server gives us control over the Transact-SQL code. For example, when things go wrong, we get a chance to do something about it and possibly make it right again. SQL Server error handling can be as simple as just logging that something happened, or it could be us trying to fix an error. It can even be translating the error in SQL language because we all know how technical SQL Server error messages could get making no sense and hard to understand. Luckily, we have a chance to translate those messages into something more meaningful to pass on to the users, developers, etc.

4K resolution and high DPI: What you need to know about it to have great visuals

April 26, 2018 by

4K resolution, AKA Ultra HD, refers to a horizontal screen display resolution in the order of approximately 3,840 pixels. On two-dimensional display devices such as computer monitors, it represents display resolution of 3840×2160 pixels which is four times as many pixels as regular Full High Definition (1920×1080). What this means for users is the more pixels per inch (PPI) the higher resolution on the monitor. In other words, you can be closer to the monitor and still enjoy a crisp, clear picture.

How to configure Database Mail in SQL Server

November 22, 2017 by

Database Mail, as you would expect from its name, is a solution for sending e-mail messages from the SQL Server Database Engine to users. Using Database Mail, database applications can send e-mail messages that can, for example, contain query results or simply alert a user about an event that occurred in the database.

The process of Database Mail configuration has three main steps. In order to complete this successfully, we need to:

  • create a Database Mail account,
  • create a Database Mail profile,
  • and configure those two to work together
