The selection of Transact-SQL for configuring firewall rules for databases in Azure is appropriate due to the functionality it provides in managing Azure SQL Database. Transact-SQL (T-SQL) is the primary programming language used to interact with SQL Server and Azure SQL Database, allowing you to execute a range of commands directly on the database, including the creation and management of firewall rules.

Configuring firewall rules using T-SQL is particularly beneficial because it allows for direct execution within the context of the database, providing precise control over the rules applied to that specific instance. This can include defining which IP addresses or ranges are allowed to connect to the database, making it a straightforward and efficient method for securing access.

Other methods like Azure PowerShell, the REST API, and the Azure Portal can also be used to configure firewall rules, each with its specific interfaces and purposes. However, T-SQL specifically allows the user to perform database-specific commands seamlessly within SQL Server Management Studio or through other database query tools. This level of integration and specificity makes it an advantageous choice for configuring firewall rules in Azure, particularly for users who are already familiar with T-SQL and working within the database environment.
