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.

Continuous Database Delivery (CD) using SQL Server Tools SqlPackage.exe

August 14, 2018 by

A little curiosity on my part led me to research a little further on the available pieces of SQL Server Tools. A cross-platform tool for continuous integration and deployment, called SqlPackage, is part of SQL Server Data Tools. I picked it up because continuous integration, delivery and deployment are now must-have in the modern-day application development paradigm.

We’d talk about the following in this article:

  1. The Database Management Life Cycle
  2. Complexities of the database release management process
  3. Introduction to SQL Server Data Tools and SqlPackage
  4. Using SqlPackage.exe, with examples

The BCP (Bulk Copy Program) command in action

August 13, 2018 by

There are various methods available for bulk data operations.

  1. BCP utility
  2. BULK INSERT
  3. Using OPENROWSET
  4. Import/Export wizard

The BCP (Bulk Copy Program) utility is a command line that program that bulk-copies data between a SQL instance and a data file using a special format file. The BCP utility can be used to import large numbers of rows into SQL Server or export SQL Server data into files. The BCP data files don’t include any schema details or format information. Hence, it is recommended to create a format file to record the data format so in case of any failures, you can refer to the format file and better understand the data format to determine what may have gone wrong..

We’ve been using the BCP tool for a long time, the reason being that it has a very low overhead, and works great for bulk exporting and importing of data. It is one of the most efficient ways to handle bulk import and export of data.
