Your investigation shows the root cause is a query against a read-only table that has a clustered index. The query returns the following six columns: * One column in its WHERE clause contained in a non-clustered index * Four additional columns * One COUNT (*) column based on a grouping of the four additional columns.

CREATE DATABASE ENCRYPTION KEY
WITH ALGORITHM = AES_256
ENCRYPTION BY SERVER CERTIFICATE TDE_Certificate;
