What will be the outcome of executing the command cells intended to register a view of sales that occurred in African countries?

What will be the outcome of executing the command cells intended to register a view of sales that occurred in African countries?

• A. Both commands will succeed, showing countries_af and sales_af registered as views.
• B. Cmd 1 will succeed, and Cmd 2 will fail because the view does not exist.
• C. Cmd 1 will succeed and Cmd 2 will fail, with countries_af being a Python variable.
• D. Cmd 1 will succeed and Cmd 2 will complete successfully.

Answer: (C)

When executing commands intended to register views, understanding the command's context and the nature of the variables being utilized is critical. For part one, if the command is designed to register a view of countries in Africa (let's say `countries_af`), and it executes without errors, it indicates that the view has been successfully registered in the session. Therefore, `cmd 1` is expected to succeed. In the context of `cmd 2`, if it tries to reference `countries_af`, but this identifier is being treated as a Python variable rather than a valid SQL view, then `cmd 2` would encounter an error. This would be because the system expects a SQL view but will not recognize a simple variable if it hasn't been appropriately defined or cast in the right context for SQL execution. The fact that `countries_af` is treated as a variable indicates that it might not have been registered correctly as a SQL view before `cmd 2` is executed, leading to a failure in that command while `cmd 1` succeeds. Thus, the correct answer reflects the scenario where the first command executes successfully, establishing the SQL view, while the second command fails due to improper recognition or context of a Python variable, leading to the conclusion that
