SQL Unit Testing: Working with exceptions

May 21, 2019 by

With this article, we will complete our journey with SQL Unit Testing. But first, let’s remember the main theme of the SQL Unit Testing again briefly. With the help of the SQL Unit Testing, we can detect and find out the flaws and bugs in database projects. This reduces the possible loss of time and money and reputation during the use of the product. However, it should be kept in mind that no matter how many tests are carried out, there will still be some bugs in the project, but SQL unit tests provide a greater degree of confidence. The fact that there are no bugs or flaws in the application at that time does not mean that the application is perfect. We cannot test all combinations and probabilities of the database objects. That is why in real life, considering certain parameters (risk, priority, etc.) we must ensure that a “reasonably sufficient” test is done.

SQL unit testing best practices

April 8, 2019 by

SQL unit testing is a testing method which allows us to test the smallest, atomic programmable part of a database object. SQL unit testing plays a key role in the modern database development cycle because it allows us to test individual parts of the database objects work as expected. SQL unit testing adds a great worth to the database project because unit tests are more reliable then manual test methods.

SQL unit testing with the tSQLt framework for beginners

March 18, 2019 by

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.

How to use JSON data in SSRS

November 6, 2018 by

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?

JSON is an abbreviation for JavaScriptObjectNotation. The main purpose of JSON data was to provide data transfer between server and web applications for JavaScript but today’s JSON is the most popular data interchange format. JSON offers two advantages to us. These are; light-weight text based format easily readable by humans. Currently, JSON is not only used in JavaScript applications, it is also used in all popular software programing languages like JavaScript, C++, C#, Perl, Java, Python, Php etc.

Forecast SQL backup size

October 23, 2018 by

This article will cover the process of analyzing and predicting/forecasting the size of a SQL backup as a means to better handle/manage retention of backups.

One of the main database management tenets is “Do not lose your data”. According to this; a database administrator incurs huge responsibilities to protect data. Under these circumstances, taking database backups and archiving SQL backup files is a key task for database administrators. In data protection strategy, taking database backups and archiving backup file processes play the leading role. Especially, backup planning is very significant for disaster recovery scenarios because backup file will be used for restore operation after any failure or data corruption. For this reason, every dba must generate recovery strategies for possible disaster scenarios and ensure that these scenarios can be solvable. At the same time, these backup files must be tested for data integrity; thus process provides to evaluate the recovery time and integrity of backup files. In this Backup and Restore (or Recovery) strategies for SQL Server database article you can find all details about backup and restore strategies.

How to add parameters to SSRS mobile reports

October 12, 2018 by

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.

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.
