Snowflake Exam COF-C02 Topic 6 Question 18 Discussion

Actual exam question for Snowflake's COF-C02 exam
Question #: 18
Topic #: 6
[All COF-C02 Questions]

Which types of subqueries does Snowflake support? (Select TWO).

Show Suggested Answer Hide Answer
Suggested Answer: B

According to the Snowflake documentation1, a directory table stores a catalog of staged files in cloud storage and can be queried to retrieve theSnowflake-hosted file URLto each file in the stage. A file URL has the following format:

https:///api/files/<db_name>.<schema_name>.<stage_name>/<relative_path>

Based on this information, I think the query that contains a Snowflake hosted file URL in a directory table for a stage named bronzestage isB. select * from directory(@bronzestage);

Wait, Snowflake supports subqueries? I thought it was just for storing snowballs! All these options are making my head spin like a snowglobe.

B and E, baby! Uncorrelated scalar subqueries and correlated/uncorrelated EXISTS, ANY/ALL, and IN subqueries. Snowflake's got my back, that's for sure.

Hmm, tricky one. I'm going to go with C. Uncorrelated subqueries are where it's at. Correlated subqueries? That's so last season, am I right?

E, E, E! That's the one that makes the most sense. Correlated or uncorrelated, I'll take it! Snowflake really does have it all, doesn't it?

I prefer having the option to use correlated or uncorrelated subqueries. It gives me more flexibility in my queries.

A and B, for sure! Uncorrelated scalar subqueries are the way to go in Snowflake. I can't believe they even included those other options - correlated subqueries? In my Snowflake? Not a chance!
