+Clear the plan cache for all batches and stored procedures that access the table to refresh parameters encryption information.

+   > Use `ALTER DATABASE SCOPED CONFIGURATION CLEAR PROCEDURE_CACHE` or `DBCC FREEPROCCACHE` to clear the plan cache carefully, as it can result in temporary query performance degradation. To minimize the negative impact of clearing the cache, you can selectively remove the plans for only the impacted queries.
