SnowPro Advanced Architect

An Architect is collaborating with a healthcare company’s Enterprise data-governance team to review how company-sensitive data is protected in Snowflake. Physicians in the company network can query views. Two views exist: one displays mental-health information, and the other displays physical-health information:

create view mental_health_view as select * from patients where category = 'MentalHealth';  
  
create view physical_health_view as select * from patients where category = 'PhysicalHealth';  

Most physicians do not have direct access to the table. Instead, they are assigned one of two roles:

1. MentalHealth, which has privileges to read from mental_health_view; or
2. PhysicalHealth, which has privileges to read from physical_health_view.

A physician with the PhysicalHealth role wants to determine whether any mental-health patients exist in the table and runs the following query:

select * from physical_health_view where 1/iff(category = 'MentalHealth', 0, 1) = 1;  

How will this query affect the sensitive data?
