A. Create a secure view that joins tables from different databases using fully qualified names (e.g., 'DATABASEI .SCHEMAI . TABLET) and implement row-level security using a masking policy based on the CURRENT_ROLE() function.

B. Create a standard view that joins tables from different databases using aliases and implement row-level security using a UDF that checks the consumer's role and filters the data accordingly.

C. Create a secure view that joins tables from different databases and implement row-level security using a row access policy based on the CURRENT ROLE() function. Masking policy cannot provide role based access control so will not work.

D. Create a view for each table and then build a final view using 'UNION ALL' to combine data from all the views and implement row-level security with a role based row access policy. Standard views should not be used in data sharing.

E. Create a standard view with a stored procedure to handle the joins across databases and use EXECUTE AS OWNER to avoid permission issues. This standard view should be shared.
