In particular, this article will focus about unit test theory in terms of SQL Server database development aspect and illustrate SQL unit testing with a detailed example.Read more »
In this article, we will show how to work with SQL random numbers in SSIS. To demonstrate this, we will have a table with people and we will create a winner randomly from that list.Read more »
We have been exploring the SQL Server FILESTREAM feature in this ongoing series of articles. In this previous article, Managing data with SQL Server FILESTREAM tables, we wrote about inserting FILESTREAM data into a FILESTREAM table and performing DML activities on it. Suppose we have created the FILESTREAM database in our instance and now we want to insert a large number of files into a FILESTREAM container. It is easy to write out the insert queries for a small number of files, but if the numbers of files were in huge quantity, it would be difficult to write out the code and insert data into it. It is difficult to manage such kind of requests regularly in the environment.Read more »
CSV (comma separated values) is one of the most popular formats for datasets used in machine learning and data science. MS Excel can be used for basic manipulation of data in CSV format. We often need to execute complex SQL queries on CSV files, which is not possible with MS Excel. See this article for what is possible with Power BI.
However, before we can execute complex SQL queries on CSV files, we need to convert CSV files to data tables.Read more »
The Q&A feature in Power BI desktop provides a way to move towards Artificial Intelligence. In my previous article, we learned about the prominent Q&A in Power BI Desktop feature. We can get the desired result from Power BI Desktop by asking a question in Natural language. It converts the result set in tabular, chart format based on the requirement. It also helps users to build the question with its intelligence. It is one of the most incredible features of Power BI.
In this article, we are going to learn how to use Power BI Desktop Q&A functionality to enable users to ask the question from the data set and easily get the results without any configuration or write complex codes.
In this article, we will explore the Flow Map chart in Power BI Desktop. Power BI is helpful to visualize the data through various form of the inbuilt and the custom charts. We have explored few such important charts in previous articles. Below is the list of articles for reference
In this article, we will learn Key Performance Indicators usage in Power BI and solve a business case problem through Power BI.Read more »
One calculation that you are almost guaranteed to have to produce in your career as a T-SQL developer relates to the calculation of a turnaround time. This is often a key KPI for measuring the performance of both individuals and teams, particularly when the business operates within a service-oriented sector i.e. customer support, transportation, healthcare etc. Turnaround time calculation does not only refer to business metrics rather any activity (i.e. ordering a pizza) with a recorded start and an end time can have its own turnaround time calculated. In this article we evaluate different options for calculating a turnaround time including using DATEDIFF function, creating your own user-defined function (UDF) as well as an integration with SQL Server Master Data Services.Read more »
SQL Server Agent is a Microsoft Windows service which helps to execute, schedule and automatize T-SQL queries, Integration Service Package, SQL Server Analysis Service queries, executable programs, operating system, and PowerShell commands. These actions which are performed by SQL Server can be called by the SQL Server Agent. Maybe, we can liken SQL Server Agent to an alarm clock because the agent will execute the scheduled task when the time comesRead more »
Power BI has a rich set of visuals to represent data according to our requirements. These custom visuals make it easy for us to highlight data effectively to understand and share the data in reports. We have learned many customized visuals so far in ongoing series of Power BI Desktop.Read more »
In the article, How to embed a Power BI Report Server report into an ASP.Net web application, we looked at available options for embedding a Power BI Report Server report into an ASP.NET web application. Since the publication of the article, I have received several questions relating to how one goes about programmatically passing credentials for report server connection within an embedded Power BI Report Server report. The simple answer to such questions is that it is currently not possible to implement user impersonation in an embedded Power BI Report Server. However, like in most scenarios, there are workarounds that one could temporarily employ – at least until Microsoft comes up with a permanent solution to what is becoming a top requested feature at ideas.powerbi.com.Read more »
CDS for Apps VS Power Query – is there a difference? If so, what is that difference? Are they mutually exclusive or complement each other? Later I briefly outline
Common Data Services for Analytics no, Power BI Datapools no again, actually Power BI Data Flows. It is difficult to keep up with the correct naming.

In my last articles on Power BI Desktop (see the index at the bottom of the article), we have explored that Power BI has a rich set of visualizations. We can present data using various custom visuals available from Microsoft AppSource. These visuals are available free to download and use it as per our requirements.Read more »
In this article, we will explore the concept of using JSON data in SQL Server Reporting Services (SSRS). This usage concept will include a different approach than the usual methodologies because we will take advantage of SQL Server R service support.
What is JSON?
In this article, I’ll share some of the tricks and tips that I had to employ in order to successfully replicate Excel’ XY Scatter Report Chart.Read more »
This article will explain detailed usage of parameters in mobile reports in SSRS. Parameterized reports are important because report readers want to filter and customize their report data with parameters and this option helps report readers to focus on particular data. A parameterized SSRS report uses parameters as an input value and filters the report data according to these parameters. In this article we will focus, in particular, on how to use parameters and data sources together and how can we manage the parameters in mobile SSRS reports.Read more »

Performance monitoring is a very significant and essential topic for database or system administrators. This is no different with SSRS load testing. In some cases, performance problems can lead to significant system downtime. Most of the time in the background of the problem is having insufficient resources or improper settings. Therefore, before experiencing performance issues, we have to take some time to review preventive measures related to current system configurations or new installations. The load test (or stress test) is the most commonly used approach to tune systems before real-life staging conditions. Now we will discuss the details of load test, and in particular SSRS load testing.Read more »
Every once in a while, teams from different functional areas of the business (i.e. business intelligence, software development, web development etc.) would join forces to form a cross-functional development team with a common goal of integrating a business intelligence artefact such as a SQL Server Reporting Services (SSRS) report into a front-end web application. There are many reasons for forming such a partnership including a lack of report-development skill by web developers, BI team owns a better reporting tool for data visualization, or maybe to prevent the software team from “reinventing the wheel” by developing a report that has already been produced elsewhere.Read more »
