Additionally, if you look at the details from the Columnstore index operator, while it says the Actual Number of Rows to zero, it does process rows as Actual Number of Locally Aggregated Rows. It sets the number of rows or non NULL column values. I have a c# code which updates the table by filling a Dataset. Using Like Query with wildcard in different combinations, we can match our keyword with the pattern of the data Sort the results by the employees' first AUTO_INCREMENT option allows you to automatically generate unique integer numbers (IDs, identity, sequence) for a column.
