It has been a while since I wrote a blog post for TSQL Tuesday and there is no better time then now following on from Brent Ozar’s Invite about our favourite data types in SQL server.

Azure SQL Database – Contained user Model
I always follow a contained user model when setting up users within my Azure SQL Database. I do this so the user in question has access to only specific database(s) and does not have a login to the server. It becomes even more apparent the importance of this when you design a solution based on failover groups.
When a failover occurs to the secondary, I want a pleasant experience for the user. With the contained user model, the user goes with the database. I don’t want to do admin work on the new primary (post failover). Let’s see.
Azure SQL Database F and M series
Taking a screen shot from my Azure Portal, you will see the available hardware configurations available for Azure SQL Database.
Azure SQL Database Gen4 to Gen 5
For the past year Microsoft have said that Generation 4 hardware is soon coming to its end of life. I know many installations that have used Generation 4 over 5 so its time to think of the plan to facilitate this move.
Azure SQL DB – Troubleshooting CPU issues
When you have the need to find out real time what is causing high CPU issues within your Azure SQL Database, there is nothing better than using TSQL and SSMS. Azure portal will highlight the below, this is when I made CPU contention.
Azure SQL Database and Long-Term Backups
There is a new (ish) interface to looking and configuring backups for your Azure SQL Database. This can be found within the settings section of the SQL Server.
As you can see, by default we have 7 days retention to allow for PITR – Point In Time Recovery, anything longer you will need to setup long term retention.
SQL server Linux and SQLCMD
Following on from a previous blog post (https://blobeater.blog/2021/01/15/sql-server-linux/) on installing SQL Linux, a common requirement will be the need to connect to it to issue queries, typically via SQLCMD). There isn’t too much to it but still an important step.
Azure SQL vCore vs DTU
If you are building database solutions in Azure , using Azure SQL Database then you will know that you have a purchasing option decision to make. That being should you use a vCore model or DTU approach?
SQL Server Linux
If you have come from a windows background you may be curious about the world of SQL Server Linux. Yes, the operating system and the implementation of it differs to the traditional Windows environment but once installed, it’s just good old SQL server and those lovely DBCC commands and backup statements work, all your DMVs are ready for you too.
Azure SQL Database Connectivity
Have you ever wondered how your connection from outside of Azure to your database is handled? It is important to understand that there is a difference between route(s) from when connecting inside to that of outside of Azure.
