Which of the following statements is TRUE regarding the query SELECT DurableKey FROM <TableName>?

The statement that the query is valid if is a snapshot table is correct because snapshot tables in the Caboodle data model are designed to store historical data. When you run a SELECT query on a snapshot table, including one that retrieves the DurableKey, it adheres to the expected structure and data types associated with such tables.

Snapshot tables typically maintain a consistent schema and data integrity that supports querying without causing errors, making them suitable targets for this kind of query. The DurableKey serves as a unique identifier, allowing for effective data retrieval. Because of this, the query can effectively extract the DurableKey values from a snapshot table without issues, affirming that option B is true in this context.

In contrast, the other options relate to aspects that either cannot be guaranteed or are overly restrictive. The first option implies universality across all tables, which is not accurate, as certain systems have specific requirements that must be met. The assertion about the uniqueness of the DurableKey in the results is not universally applicable since DurableKeys can repeat depending on the structure of the data model being queried. Finally, limiting the query to execute only in the PatientDim table is incorrect, as the query format provided can function with any suitable table adhering to the
