Using striped backups with SQL Clone

If you’re a Redgate SQL Backup customer, occasionally you’ll need to convert your SQL Backup (.sqb) files to the native SQL Server backup format (.bak), perhaps to perform native database restores on a server where SQL Backup isn’t installed.

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?
