Ordered Columnstore Indexes in SQL Server 2022

One of the more challenging technical details of columnstore indexes that regularly gets attention is the need for data to be ordered to allow for segment elimination. In a non-clustered columnstore index, data order is automatically applied based on the order of the underlying rowstore data. In a clustered columnstore index, though, data order is not enforced by any SQL Server process. This leaves managing data order to us, which may or may not be an easy task.

Question of the Day

Switching Schemas I

I run this query:

SELECT 
 s.name AS schemaname
 , o.name AS objectname
 FROM sys.objects o
 INNER JOIN sys.schemas s ON s.schema_id = o.schema_id
 WHERE o.name = 'Beer'
I get one row back for an object named dbo.beer. There is an ETL schema and both of these are nonpartitioned tables. I run this code:
ALTER TABLE dbo.beer switch TO etl.beer
What happens?
