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.

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.

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.

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.

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.

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.

In this article, we are going to see how to create a multi subnet cluster spanning across multiple subnets for lab purposes. Creating such an environment should help creating Availability groups simulating a far replica residing in a different Data Center (Subnet) acting as a disaster recovery site in your lab for learning/experimenting real world scenarios.

This SQL Server FILETABLE article is the continuation of the SQL Server FILESTREAM series. The SQL Server FILESTREAM feature is available from SQL Server 2008 on. We can store unstructured objects into FILESTREAM container using this feature. SQL Server 2012 introduced a new feature, SQL Server FILETABLE, built on top of the SQL FILESTREAM feature. In this article, we will explore the SQL FILETABLE feature overview and its comparison with SQL FILESTREAM.

One big component of DevSecOps surrounding security testing involves how we build and deploy with shared information access of details that may be valuable to an attacker. In order to understand these risks, we must think like attacker who wants to compromise an environment that is focusing on quickly writing code, building the code, testing it, and deploying it across multiple environments. An attacker’s ultimate target will be the highest environment – often a production environment, but some attackers may target lower environments because they may be able to inject code that is deployed to production. In addition, an attacker may only be trying to learn about how an environment is laid out to attack in other ways, such as using social engineering with key information.

In this article, we will learn the step by step configuration of SQL Server AlwaysOn High availability Group for two nodes. Once nodes are added to the cluster group, we will able to use the AlwaysOn feature in the SQL server.
A key component of DevSecOps and identical to running unit tests to validate code after a build, running automated security testing after an application has been deployed (such as automated penetration tests) can provide us with a tool that identifies security risks. As we’ve seen recently, there’s been a growth of many companies experiencing information being compromised and with the development culture of “move fast and break things”, I expect this trend of successful attacks will continue. Before we look at our options for automating this testing, we want to be aware of its limits, evaluate the requirements, and consider common designs that are useful.
