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.

Overview of the SQL Update statement

October 8, 2018 by

In this article, we’ll walk-through the SQL update statement to modify one or more existing rows in the table. 

In order to modify data in a table, we’ll use an Update statement, a DML (data manipulation language) statement. A SQL update statement comes with a SET clause where we define the column-and-value as a pair of items. In addition, you can enforce the conditional clause. In order to limit the number of rows, we’ll need to set up a where clause. The condition is defined in the where clause that identifies what rows to modify in the table.

Load testing for SQL Server Reporting Services (SSRS)

September 25, 2018 by

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.

How to embed a Power BI Report Server report into an ASP.Net web application

September 20, 2018 by

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.

Available options for generating heatmaps in an SSRS report

September 17, 2018 by

As developers of business intelligence solutions, we tend to service different types of business users. Whilst a call center supervisor is more likely to consume reports that offer detailed breakdown of day-to-day performance of her call center agents, senior managers on the other hand often prefer big-picture analytical reports that represent data in a form of colorful graphs and charts. Not surprisingly, such reports often make use of heatmap controls to provide visually effective comparative view of business metrics against set targets.

The requirement of data refactoring is very common and vital in data mining operations. In the previous article SQL string functions for Data Munging (Wrangling), you’ll learn the tips for getting started with SQL string functions, including the SQL substring function for data munging with SQL Server.
