Prediction, is it a new thing for you? You won’t believe you are predicting from the bed to the office and to back to the bed. Just imagine, you have a meeting at 9 AM at the office. If you are using public transport, you need to predict at what time you have to leave so that you can reach the office for the meeting on time. Time may vary by considering the time and the day of the week, and the traffic condition etc. Before you leave your home, you might predict whether it will rain today and you might want to take an umbrella or necessary clothes with you. If you are using your vehicle then the prediction time would be different. If so, you don’t need to worry about the rain but you need to consider the fuel level you need to have to reach to the office. By looking at this simple example, you will understand how critical it is to predict and you understand that all these predictions are done with your experience but not by any scientific method.Read more »
Whilst Power BI continues to be the leading data visualisation tool in Gartner’s BI quadrant, Dynamics 365 for Customer Engagement (formerly Dynamics CRM) remains one of popular business platforms for driving sales and facilitating customer communications. Thus, an integration of Power BI into Dynamics 365 for Customer Engagement ensures that you get to explore your Dynamics 365 for Customer Engagement data via a powerful and rich data visualisation tool. However, as indicated in Figure 1, Dynamics 365 for Customer Engagement plans often come with a Power BI free license thereby limiting the type of Power BI features available to you. In this article, we look at how you can get the best out of your Power BI free license for the purposes of embedding Power BI artefacts into Dynamics 365 for Customer Engagement. Going forward, any references to Dynamics 365 for Customer Engagement plan in this article will be shortened to Dynamics 365.Read more »
Power BI Desktop is a useful reporting and analytical tool to represent data in various formats. These presentations help us to quickly understand information and circulate it to stakeholders in a visual fashion.
Power BI Desktop amplifies the value of data. We can connect to multiple data sources and visualize the data interactively. One of the best parts of Power BI Desktop is the custom visual feature. It allows developers to create custom visuals and users can then download these visuals from the marketplace and use it as per the data set requirements. We can prepare reports using Power BI Desktop and share the reports using the Power BI service.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 »

Over the past three years, I read some interesting news about Microsoft which was “Microsoft acquires mobile business intelligence leader Datazen”. This news made me excited because showing Reporting Service reports in mobile devices can be painful and often not effective for end users. After this acquisition, Microsoft developers worked quickly to adapt the Datazen application to SQL Server Reporting Services and this effort culminated in Microsoft SQL Server Mobile Report Publisher.Read more »
We’ve recently had production failures because our developers changed an important reference. In this case, we had a view which several procedures and views referenced. A developer made a change to the referenced view by removing columns, which caused several procedures and a view that referenced it to fail. We’re considering whether we should stop this practice, or if there are other ways we can prevent changes to an object that’s being referenced by other objects (in our case, a view).Read more »
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.Read more »
As with everything else, all good things must come to an end. After hanging around for a good decade SQL Server 2008 and SQL Server 2008 R2 has started the countdown to its End of Life.
D-day for SQL Server 2008 and SQL Server 2008 R2 is set to the 19th of July 2019. Which is approximately a year from now, give or take a couple of months.

In today’s get together, we shall be looking at doing just this!Read more »
A few months back, I presented a paper at SQL Saturday 327 in Johannesburg, South Africa. Late last month I received an email from one of the attendees. His issue was quite interesting and I decided to share it with you. The gentleman wanted a SSIS script that would permit him to extract data from a SQL Server database table and place it in a CSV file with a dynamically allocated name. Being a strong advocate of using the SSIS toolbox, I experimented with an alternative solution. We are going to construct THIS SOLUTION in today’s get together.
Let’s get started.Read more »
