Why is your ASP.NET application running slow?

Any queries run against SQL Server or Oracle databases are recorded, along with how many times those queries were run and how long they took. That information is shown alongside your .NET code, so you can quickly see why the code you wrote resulted in those queries being executed. This can be particularly powerful if you’re using ORMs like Entity Framework to access data, which tend to be an impenetrable black box where performance issues can arise, but where it’s difficult to understand why.

Question of the Day

Getting the Average

I have this data in the dbo.Commission table in a SQL Server 2022 database. 

salesperson commission
Brian       12
Brian       16
Andy        7
Andy        14
Andy        21
Steve       20
Steve       NULL
All the data is a varchar, and I decide to run this query to get the totals for each salesperson. 
SELECT SalesPerson
     , AVG(TRY_PARSE(Commission AS int)) AS TotalCommission
 FROM commission
 GROUP BY SalesPerson
GO
What average commission is calculated for Steve?
