SQL Server FILETABLE provides benefits over SQL FILESTREAM available from SQL Server 2012. We can manage unstructured objects in the file system using SQL Server. It stores metadata in particular fixed schema tables and columns. It provides compatibility between an object in SQL Server table and Windows.Read more »
This article is about basics of conventional SQL unit testing concepts and its implementation through tSQLt, a highly acclaimed SQL unit testing framework because of being written in T-SQL and its built-in design support for SQL SQL unit testing needs ranging from simple to complex scenarios.

This article is the sequel in a series about SQL Server monitoring tools and common performance issues. The first article SQL Server monitoring tools for disk I/O performance is about how to detect and solve high input/output on hard disk subsystems when doing too much work during peak or maintenance times.
Nested Triggers in SQL Server are actions that automatically execute when a certain database operation is performed, for example, INSERT, DROP, UPDATE etc.Read more »
Both log shipping and mirroring are high availability and disaster recovery options available in SQL Server. This article will review on how to configure log shipping on a mirrored database.Read more »
This article will review on how to configure SQL Server Replication along with mirroring on a database.
We have a convenient tool for working with PowerShell and SQL Server when using Invoke-SqlCmd. As we saw when running statements, we can run DDL and DML changes with the command without writing our own custom scripts. This carries advantages when we need to quickly develop with PowerShell, but it can come with drawbacks on security if we’re not careful how we use this function. We’ll look at security when using this function by starting with a few examples of what we can do when we have unlimited access along with how we can design to limit our environment to be strict with our use of this tool.Read more »
In my earlier PowerShell SQL Server article, SQL Database Backups using PowerShell Module – DBATools, we explored the importance of a disaster recovery solution for an organization. Microsoft offers various disaster recovery solutions in SQL Server.Read more »
In this article, we will review PowerShell SQL Server module DBATools to identify IDENTITY columns about to reach the threshold.Read more »
In the previous article SQL unit testing with the tSQLt framework for beginners in this series, we covered tSQLt framework essentials and installation. we also demonstrated basic SQL unit testing through the tSQLt framework. In this article, we will continue to explore SQL unit testing and we will also discuss the benefits of SQL unit testing. Additionally, we will learn how we can use the tSQLt framework in a SQL Server Database Project.Read more »
This article will provide information about requirements and step-by-step instructions on how to set up automated image based database provisioning including configuring the host environment to fulfilling basic requirements.Read more »
In this guide, we’ll discuss more about migrating a SQL Server database to Azure SQL Database using SQL Server Transactional Replication.
SQL Server FILETABLE is a next generation feature of SQL FILESTREAM. We can use it to store unstructured objects into a hierarchal directory structure. SQL Server manages SQL FILETABLE using computed columns and interacts with the OS using extended functions. We can manage SQL FILETABLEs similar to a relational table.Read more »
In my previous article in this series Accelerated Database Recovery; Instant Rollback and Database Recovery, we talked about a potential DBA painkiller to resolve long waiting times for database recovery and rollback scenarios using Accelerated Database Recovery. In this article, we will look at one more painful challenge for DBAs, Long Running Transaction with Transaction log growth.Read more »
This article will be first article of series for SQL database backup and restoration using DBAtools, a powerful open source library of PowerShell automation scripts.Read more »
In the previous article of this series on the SQL Server transaction log, we discuss the SQL Server database recovery models, Full, Simple and Bulk-Logged, and the how the recovery model option of the database affects the way the SQL Server Engine works with the transaction logs. In this article, we will discuss the different types of high availability and disaster recovery solutions and the role of the SQL Server transaction log in these technologies.
Today, with DevOps, the need for database cloning is urgent. The development and testing process is shorter and it is required to work and test the data faster.
PowerShell features many one-line commands for working with SQL Server, one of which is Invoke-SqlCmd. This tool can be useful in many development contexts where we need to quickly execute scripts or test code and it helps to know some of the parameters we’ll often use. In addition, because we may want a custom script using some of the underlying .NET objects, we’ll look at an alternative where we will be able to create a custom PowerShell script that connects to SQL Server in order to run commands. The latter can be useful because one-line scripts have a tendency to change in future versions of PowerShell and working with the library directly can sometimes avoid this challenge.Read more »
tSQLt is a powerful, open source framework for SQL Server unit testing. In this article, we will mainly focus on how to create and run SQL unit testing with help of the tSQLt framework. Before we begin to learn tSQLt framework details, let’s discuss essentials and importance of the database unit testing approach, in general. SQL unit testing is a vital and inseparable part of the modern database development approach and it makes possible to prevent errors before producing the release deployment process. Some database developers are still discussing the needs of the SQL unit testing concept; however, database unit testing is very significant to control and check the behavior of the individual parts of the database. For this reason, we cannot ignore the need to write unit test cases.Read more »
The PowerShell execution policy was developed with a vision to be friendly to administrators, and at the same time, be accessible to end users. More than the former, the latter goal was a little challenging to pull off, considering that convenience is, more often than not, inversely proportional to security.Read more »
