BA row access policy can be applied to the VALUE column of an existing external table.

CA row access policy cannot be directly added to a virtual column of an external table.

Show Suggested Answer

Suggested Answer: C

Enabling the search optimization service on the table can improve the performance of queries that have selective filtering criteria, which seems to be the case here. This service optimizes the execution of queries by creating a persistent data structure called a search access path, which allows some micro-partitions to be skipped during the scanning process. This can significantly speed up query performance without increasing compute costs1.

This is all great, but I'm just wondering - can we use row access policies to control who sees the external table's secret ingredient recipe? Asking for a friend, of course.

B is a bit surprising. I thought we could only create the policy when the external table is made, not apply it later. Interesting twist!

C and F make sense. Can't apply a policy to a virtual column or a view on an external table. Gotta keep those policies on the base table.

A, D, and E - Looks like we can create an external table with a row access policy, use it as a mapping table, and even clone the policy along with the table. Handy stuff!
