In today’s time where data breaches are highly expected to happen, there is a high need to ensure sensitive data in the Azure SQL databases is secured and which is why data security implementation is gaining momentum across each community. We covered one of the features of Advanced Data Security here in Advanced Data Security […]
This article talks about the three standard SQL unit tests which can be written against any stored procedure ultimately becoming SQL unit testing object to meet internal or external business specification.
In this article, we will review SQL Server MERGE statement, alternatives to MERGE statement, different clauses and examples of MERGE statement in SQL Server.
We extract data from SQL Server tables along with various conditions. Usually, we have data in large amounts and SQL Between operator helps to extract a specific range of data from this huge data. For example, suppose we want to know the product sales between Jan 2019 to May 2019. In this case, we can […]
DBATools is an open-source PowerShell that contains a collection of useful commands. In this series of articles on DBATools (see TOC at the bottom) we performed installation of it. We also explored commands to do database backups, database restoration, Identity column maximum range threshold and create a SQL database.
This article explores the Identity function in SQL Server with examples and differences between these functions.
This article is focussed on clever database object naming from both development and SQL unit testing point of view. This article also highlights the importance of naming database objects going through different development transitions including the SQL unit testing phase due to the agile nature of requirements.
In this article we’ll review the SQL varchar data type including a basic definition and overview, differences from varchar(n), UTF-8 support, Collation, performance considerations and more.
SQLSELECT statements are used to retrieve data from the database and also, they populate the result of the query into the result-sets. The SQL examples of this article discourse and explain the fundamental usage of the SELECT statement in the queries.
Our testing or development may call for dynamic creation on the database level for Azure Cosmos DB rather than the account level. As we’ve seen with dynamically working with a Cosmos database account using PowerShell, we can create, remove, and obtain properties of the account. Identically, we can do this on the database level as […]
Introduction to SQL Server Statistics SQL Server Statistics are an essential part of query performance in SQL Server. They help the query optimizer to prepare a query plan using the distribution of values in participating rows. If we do not have updated statistics, it might lead to resource intensive query execution plan. For example, for […]
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 […]
In this article, we will review how to create a Kubernetes cluster in Azure Kubernetes Service, provision the persistent volume to store the database files and deploy SQL server on Kubernetes cluster.
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 […]
This article explains the SQL Notebook feature in Azure Data Studio along with the Markdown language to customize it.
In this article, we will review triggers in SQL Server, different types of trigger events, trigger order and NOT FOR REPLICATION in triggers. A trigger is a database object that runs automatically when an event occurs. There are three different types of events.
This is the last article, but not least, in the SQL Server Audit series. In this series (see TOC at the bottom), we explained deeply the concept of the SQL Server Audit, why it becomes mandatory for each company to have a SQL Server Audit solution to track and log the different types of events […]
If this is your first visit to this SQL Server Transaction Log series, I recommend you first review the previous articles (see the TOC below), in order not to be familiar with the concepts that we will discuss in this article. Reviewing the previous articles, you will have a good idea about the following:
In previous articles of this SQL Server Audit series (see the TOC at the bottom), we discussed the main concept and real-life needs for having a SQL Server Audit solution. After that, we went through the different methods that can be used to audit the SQL Server instances and databases. In this article, we will […]
This article explores the SQL ISNULL function to replace NULL values in expressions or table records with examples.
Introduction The Python programming language is object oriented, easy to use and, widely used programming language. We can write simple Python SQL Scripts and it performs the task that is not easy to do with t-SQL.
In this SQL Unit testing article, we will continue our journey with SQL unit testing. In the previous articles of this series (see the TOC at the bottom), we mentioned about SQL unit testing essentials and designing approaches as well and then we reinforce these notions with various tSQLt framework practical examples. In this article, […]
A SQL Server cursor is a database object that is used to process the data in a set row by row. In this article, we will review how to create a cursor and different attributes used while declaring a cursor.
In this article series, we are exploring SQL unit testing, in general, and also we are reinforcing details and topics with various practical examples. We are using the tSQLt framework because it is the quite powerful and handy tool in order to develop and code SQL unit tests.
This article gives an overview of Orphan users and fixing them using DBATools PowerShell.
