SQL Server Tutorials
At MSSQLTips, we are committed to deliver a valuable technical tip on SQL Server every day of the week. We plan to continue our commitment and have expanded our educational opportunities to the SQL Server community with tutorials. Our intention with the tutorials is to provide a step-by-step progression on a single topic such as backups or the SELECT statement. We think some topics naturally start at A and end at Z. As such, each tutorial serves as a building block for the next one. So pick your topic below, start with the first lesson and navigate to the rest by either clicking on the links on the left of the tutorial pages or on the 'next' icon (above right and directly below the lesson).
We plan on adding new tutorials on a regular basis, so be sure to visit this page frequently to expand your knowledge. If you have any feedback on the tutorials or would like to suggest a tutorial, please let us know.

In a BI project, data is the currency and analytics is the merchandise. Without having the right type, amount and shape of data, one cannot get the right kind of analytics. In this tutorial, we will look at different types of data sources as well as relational data modeling. Data makes many hops from one layer of the solution to another in any BI solution architecture. During this data movement from source to destination, the shape of the data keeps transforming. This facilitation of data movement and transformation along the way is typically known as Extract, Transform and Load (ETL). We will look at typical ETL needs and the associated topics like data staging and master data management concepts.
In this tutorial we will go over the basics of Snowflake, introducing the product and features which makes it stand out against its competitors. We look at how to load and query data as well as how to use Power BI to create reports using the Snowflake data.
SQL Server Analysis Services (SSAS) is the technology from the Microsoft Business Intelligence stack to develop Online Analytical Processing (OLAP) solutions. Over the years SSAS has evolved and has emerged as a leader in the area of analytical solutions. SSAS generally uses a data warehouse as a data source and contains data objects like cubes, dimensions, measures, aggregations hosted in a SSAS database. SSAS also offers options to select a variety of server modes like Multi-dimensional, Tabular and PowerPivot. Multi-dimensional expressions (MDX) and Data Analysis Expressions (DAX) are the two primary query and expression languages which are used to query SSAS database objects.
This tutorial is intended to help experienced T-SQL Developers, DBAs, Data Analysts and Data Science enthusiasts to start using Python language with T-SQL. This enables data science and analytics tasks closest to the actual data, without the need to follow a traditional BI methodology of transporting and transforming data across repositories. The tutorial is structured in five lessons, with each lesson focused on explaining corresponding key points.
Administration of a SSAS instance / database is similar to SQL Server Database Engine management in some ways. There are some administration aspects which are also unique to SSAS like processing dimensions, facts and cubes. Any IT environment employing SSAS as its OLAP technology typically involves the following administrative tasks. These tasks are an integral part of any SSAS solution that Developers as well as DBAs need to perform in production and/or non-production environments depending on their role on the team.

Database Administration Tutorials
From time to time companies initiate projects to move from one database platform to another. Such migrations can involve switching between database engines such as SQL Server, MySQL, Oracle, Sybase, DB2, etc. In this tutorial we will explore the differences between MySQL and Microsoft SQL Server and the key components that you should be aware of when making that move.
Since its initial release in 1989, SQL Server has come a long way from its base functionality as an enterprise level database platform. While the core of SQL Server is still it's database engine, it is now so much more than just a relational database platform. We now have Analysis Services for online analytical processing, Reporting Services for developing reports, Integration Services for developing and running ETL programs as well as many other tools and services that work with and/or support these core components.
One of your last lines of defense for just about any system is to have a backup in place in case there is a need to recover some or all of your data. This is also true for SQL Server. In this tutorial we will discuss selecting the correct recovery models, what backup options are available, and how to create backups using T-SQL commands and SQL Server Management Studio.
In this tutorial / reference guide we cover several SQL Server functions that are related to dates such as YEAR, MONTH, DATEPART, DATENAME, GETDATE and many more. Each function also includes several examples of the usage and the syntax.
Learn about SQL Server Extended Events including the architecture, numerous ways to setup new sessions, templates, editor tips, creating or altering sessions, associated DMVs and more.
When SQL Server executes a query it uses a query plan to determine how to access data and complete the query. SQL Server offers DBAs and developers the ability to see these query plans to assist in query optimization. Without query plans it would be difficult to figure out how to tune and optimize your queries. In this tutorial we explore how to read and use Graphical Execution Plans.
Although there are many different things that can be done to improve the performance of a database system, creating indexes is the main tool in every DBA's toolbox that is used when we are trying to improve the performance of a query. This tutorial covers different types of SQL Server indexes and how they can be used.
The INFORMATION_SCHEMA views allow you to retrieve metadata about the objects within a database. These views can be found in the master database under Views / System Views and be called from any database in your SQL Server instance. In this tutorial we look at some of these INFORMATION_SCHEMA views and how they can be used.
SQL Server Management Studio, also known as SSMS, is an intuitive and multi-purpose database development and administration tool primarily used by SQL Professionals including SQL database developers, database administrators and infrastructure teams to manage SQL Server environments.
This tutorial is focused on SQL Server Management Studio (SSMS) essentials alongside some short walkthroughs, links and tips for beginners to get started and for experienced professionals to learn something new about this highly productive tool.

In this tutorial we will cover common questions related to the SQL Server msdb database. This is one of the standard system databases that are part of every SQL Server installation. This tutorial will give you a better idea of what the msdb database is used for, how to configure and maintain it and how to know what data and objects are stored in the msdb database.
In this tutorial we will cover some of the common issues with performance such as: deadlocks, blocking, missing and unused indexes, I/O bottlenecks, poor query plans, statistics, wait stats and fragmentation.
SQL Profiler is a tool that provides a user interface to the SQL Trace utility which gathers events as they occur in your SQL Server instance. It gives you the ability to monitor everything that is going on inside your SQL Server instance. SQL Profiler provides you with an easy to use interface that allows you to select the events you want to monitor and where you want the output to be saved without having to know all the system stored procedures that are a part of SQL Trace. Without this tool you would have to go through the tedious process of manually setting up each event and filter with individual stored procedure calls for every event you want configured in your trace.
In my years being a DBA I’ve seen many (even made some myself) common mistakes when reviewing the SQL queries that run against the systems I maintain. With this experience I’ve found that there are a some general guidelines that should be followed when writing queries and also when designing a database schema. In this tutorial we will take a look at a few different areas where these common mistakes are made and what can be done to fix them. These areas include: Query writing, Indexing and Schema design.
What good is a backup if you do not know to restore the backup. In this tutorial we will look at what restore options are available and which options are only accessible using T-SQL commands.
In this tutorial / reference guide we cover several SQL Server functions that are related to strings such as LEN, TRIM, SUBSTRING, LOWER, UPPER and many more. Each function also includes several examples of the usage and the syntax.
In this tutorial, we’ll go over some of the tasks you can do to manage the transaction log. The transaction log is very important to SQL Server and there are books alone that discuss how to manage the log so this will be an introduction tutorial to the transaction log.
In this tutorial learn about SQL Server triggers and how these can be used to run additional code after an event occurs like inserting or changing data.
Performance Monitor (PerfMon) is a tool that comes built-in with Windows and allows you to look into the performance of your system and the applications that are running on it. It gives you a way to view data points that are associated with these applications and link them with the effect they have on your system. You can monitor data points both in real-time or collect them for analysis at a later time. Collection can also be scheduled for specific times of the day if there are only specific windows of time where you are experiencing an issue that you would like to monitor.
SQL Server Data Tools (SSDT) SQL Projects offer excellent functionality to relieve developers of the mundane, manual tasks involved with maintaining databases. If your company licenses Visual Studio 2010 or 2012 Professional or greater, you have the ability to create Visual Studio SSDT SQL Projects. With these projects, you can add your database objects and the Visual Studio engine will figure out for you the dependencies between objects as well as the differences between schemas and apply them which can mitigate some of the errors that can occur when working with scripts manually.
The goal of this tutorial is to help non-database and database professionals alike recognize sound development practices and to recognize practices and techniques that could lead to future technical headaches.
In this video tutorial we will look at the different data types that SQL Server offers for storing date and times in a database table. We will compare the differences for the data types as well as do a storage test to determine the difference for each date data type.
The INSERT command is used in SQL Server to add records to a table. It is a fairly straightforward command that can be used in ad-hoc code and stored procedures. In this tutorial we cover the following topics: simple INSERT statement, verify the INSERT commands, INSERT command with variables, INSERTs using stored procedures and more.
We can use regular expressions (sometimes called Regex) with T-SQL to tackle some common problems with data using this tool. In this tutorial, we will practice using regular expressions for filtering precise phrases involving alphabetic, numeric and special characters. By the end of this tutorial, we should have another skill for precisely filtering data if needed.
If you are starting to learn the T-SQL language then starting with the SELECT statement makes a great deal of sense. The SELECT statement is the core command to access data in SQL Server.
A stored procedure is nothing more than prepared SQL code that you save so you can reuse the code over and over again. So if you think about a query that you write over and over again, instead of having to write that query each time you would save it as a stored procedure and then just call the stored procedure to execute the SQL code that you saved as part of the stored procedure. In this tutorial we cover how to create stored procedures in SQL Server.
In this tutorial, we’ll give you an introduction to the concepts and usage of the window functions. Learning about these functions and applying them in your everyday programming will make you write better and more efficient T-SQL. After some introduction work, we’ll go over some of the different categories of window functions like: row_number, over, lag, lead and more.
Visual Studio 2010 Database Projects offer excellent functionality to relieve developers of the mundane, manual tasks involved with maintaining databases. If your company licenses Visual Studio 2010 Professional or greater, you have the ability to create Visual Studio Database Projects.
