The Need for a Data Catalog

In the event of a breach of personal data, any organization must produce proof that they understand what data they hold and where, and how it is being used, and that they have enforced the required standards for access control and security. To make all this possible, it is essential to build a complete model of the data and its lineage, and a data catalog is the first step in this process.

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?
