SQL Server Central Webinar Series #23: Safeguard your data offsite with SQL Backup Pro

You may already have a great backup and recovery plan. However, if something were to happen to your databases and you needed to restore from your backups, you’d want to be in control, with the ability to access a copy of those backups quickly, restoring them with minimal downtime and minimal fuss.

In this session Grant Fritchey, SQL Server MVP, will discuss the key reasons why you need to have offsite backups, and the advantages of hosted storage. He’ll address some of the fears surrounding cloud backups, and show how offsite backup is made quick and easy with the new ‘backup to hosted storage’ features in SQL Backup Pro 7.3.

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?
