Question of the Day

The Updated Columns List

I have this table in SQL Server 2022: 

CREATE TABLE CustomerLarge
  (CustomerID               INT NOT NULL IDENTITY(1, 1) CONSTRAINT CustomerLargePK PRIMARY KEY CLUSTERED
 , CustomerName             VARCHAR(20)
 , CustomerContactFirstName VARCHAR(40)
 , CustomerContactLastName  VARCHAR(40)
 , Address                  VARCHAR(20)
 , Address2                 VARCHAR(20)
 , City                     VARCHAR(20)
 , CountryCode              CHAR(3)
 , Postal                   VARCHAR(20)
)
GO
If I check the columns_updated() function return in a trigger, what is the data returned?
