Use the following code to run a test with base CTE cardinality of 2 (requires 5 additional levels of CTEs): DECLARE @low AS BIGINT = 1 , @high AS BIGINT = 100000000 ; WITH. I tested my solutions in SQL Server 2019 Enterprise edition. SQL Server chose row mode processing for all previously shown solutions by default.
