Improving the Quality of SQL Server Database Connections in the Cloud

To access SQL Server from the client, you use TDS protocol over TCP. This is fine over reliable LANs but over the internet these connections are relatively slow and fragile. TDS is still used to connect to databases in the cloud, but you need to use a combination of the new features such as connection pools and idle connection resiliency to make applications faster and more reliable. Edward Elliott shows you how.

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?
