Using RANK and DENSE_RANK Functions in MySQL

Overview of MySQL Window Functions

October 1, 2021 by

In this article, we are going to learn about the different types of MySQL Window Functions and how to use them as per different use cases. MySQL is one of the most commonly used databases in the software world today. Almost every other web application running uses MySQL as a database, either on-premise or on the cloud. It becomes extremely necessary for developers and database users to master their querying abilities such that they can query the databases as per the requirements and produce suitable results. In this article, we are going to focus on the MySQL Window Functions and how to use them with practical examples. An important point to note is that most of the MySQL Window Functions are applicable only to versions 8 or higher.

Check encryption state after TDE SCAN

Understanding the TDE SCAN process in Transparent Data Encryption

September 30, 2021 by

Transparent Data Encryption is a SQL Server feature that is used to protect data stored in SQL Server databases. The process to enable TDE on any user database is a straightforward method. Once we enable TDE on any user database, SQL Server performs a scan for each data page into the buffer pool and then writes the encrypted pages back to disk. The process of scanning each data page is known as TDE scan. Any database is fully encrypted once the TDE scan will be completed for all data pages of the database.

In this article, we are going to learn how we can write a SQL query with space in the column name. Blanks spaces are restricted in the naming convention of the database object’s name and column name of the table. If you want to include the blanks space in the object name or column name, the query and application code must be written differently. You must be careful and precise while writing dynamic SQL queries. This article explains how we can handle object names and columns with blank space in SQL Server and MySQL.

Queue Function triggered - Queue Storage in Azure

Triggering Function Apps from Azure Queue Storage

September 23, 2021 by

In this article, we are going to learn how to trigger Function Apps from Queue Storage in Azure. Function Apps has been one of the most popular cloud services of Microsoft Azure. Function Apps allow users to write code in any language and then execute the code in the cloud. There is no infrastructure to be managed and hence is very flexible for writing and building applications on the go. Every Function App can be triggered in multiple ways, for example, by calling the function URL using an HTTP endpoint or from some other functions in Azure. In this article, we are going to trigger the Function App from Queue Storage in Azure and see how to pass a message from the queue to the Function App.

Check transparent data encryption state of tempdb and user database after enabling it

Impact of TDE (Transparent Data Encryption) on Tempdb databases

September 15, 2021 by

This article will explain the impact of TDE (Transparent Data Encryption) on one of the crucial system databases, tempdb. Everybody wants to secure their data to prevent unauthorized access and use. SQL Server is a very popular enterprise RDBMS system that is used to store client’s data inside their databases. It also offers multiple features to secure the data stored in the databases. TDE (Transparent Data Encryption) is one of those features which is used to secure SQL Server databases by encrypting their database files. TDE protects data by applying encryption using a certificate which is also protected by the master key.
