Another re-post of a video from last year, this time showing you an in-built protection of setting max server memory for your SQL Server. You can clearly see that if you enter a silly figure such as 50 MB, the minimum memory amount allowable for max server memory is 128 MB. You will see SSMS (SQL Server Management Studio) change it to 128MB.
SQL Server Deadlocks
A quick video clip showing how to create a deadlock in SQL Server and find information about it.
T-SQL Tuesday Sharing Cookies
It has been a while since I have participated in a T-SQL Tuesday but I felt the urge to do so this month because of the host – Shane O’Neill (a good friend) and the topic of cookies (not the edible type).

Azure SQL Data Warehouse Query Store
I personally think that query store has been a fantastic feature. I find myself using it for query performance troubleshooting (plan regressions is a big one). This has always been available since SQL Server 2016 and even Azure SQL Database but now Microsoft have made it available for Azure SQL Data Warehouse (DW).
If you connect to the Azure SQL DW via SQL Server Management Studio (SSMS) there is no Query Store Node (for the version, I was checking 17.9.1). I was even wondering if it was on by default?
Azure SQL Database and Trace Flags
You cannot enable trace flags (globally or by session) within Azure SQL Database but did you know that some global trace flags are enabled by default?
What is on?
