Can I use Snowflake Row Access Policies on External Tables?
Yes. You can use Row Access Policies on External Tables. Similar to regular tables, you can add a row access policy for when you CREATE the external table or you can ALTER the external table and add a Row Access Policy. \n\nKEY POINTS on EXTERNAL TABLES and ROW ACCESS POLICIES (RAP)\n*You cannot add a row access policy to a virtual column directly [The only way to work around this would be to create a view on top of the external table and apply the RAP to the view columns)\n*When you clone \n*You cannot use an external table as a mapping table within a row access policy at this time. \n\nIf the data in the external table is necessary for the row access policy, consider moving the external table data to a dedicated schema within the database in which the row access policy exists prior to completing a clone operation. Update the row access policy to reference the fully qualified table name to ensure the policy refers to a table in the cloned database.
