[All COF-C02 Questions]

What is a limitation of a Materialized View?

AA Materialized View cannot support any aggregate functions

BA Materialized View can only reference up to two tables

CA Materialized View cannot be joined with other tables

DA Materialized View cannot be defined with a JOIN

Show Suggested Answer

Suggested Answer: D

Materialized Views in Snowflake are designed to store the result of a query and can be refreshed to maintain up-to-date data. However, they have certain limitations, one of which is that they cannot be defined using a JOIN clause. This means that a Materialized View can only be created based on a single source table and cannot combine data from multiple tables using JOIN operations.

A Materialized View can support aggregate functions, that's not true.

I think D sounds familiar, but I can't quite remember if you can define a materialized view with a JOIN or not.

I vaguely recall that materialized views can be joined with other tables, so C might not be correct either.

I’m not sure about the limit on tables, but I feel like I’ve seen questions about materialized views referencing more than two tables.

I think I remember that materialized views can actually support aggregate functions, so A seems wrong.

I’m confused about D; I thought you could define a materialized view with a JOIN, but I need to double-check that.

I practiced a question about joins with materialized views, and I think they can be joined with other tables, so C seems off.

I’m not entirely sure, but I feel like materialized views can reference more than two tables. Maybe that rules out B?
