Snowflake Exam ARA-C01 Topic 3 Question 39 Discussion

Actual exam question for Snowflake's ARA-C01 exam

Question #: 39
Topic #: 3

When loading data into a table that captures the load time in a column with a default value of either CURRENT_TIME () or CURRENT_TIMESTAMP () what will occur?

AAll rows loaded using a specific COPY statement will have varying timestamps based on when the rows were inserted.

BAny rows loaded using a specific COPY statement will have varying timestamps based on when the rows were read from the source.

CAny rows loaded using a specific COPY statement will have varying timestamps based on when the rows were created in the source.

DAll rows loaded using a specific COPY statement will have the same timestamp value.

Show Suggested Answer

Suggested Answer: D

When using the COPY command to load data into Snowflake, if a column has a default value set to CURRENT_TIME() or CURRENT_TIMESTAMP(), all rows loaded by that specific COPY command will have the same timestamp. This is because the default value for the timestamp is evaluated at the start of the COPY operation, and that same value is applied to all rows loaded by that operation.

I'm not sure, but I think the answer might be C) Any rows loaded using a specific COPY statement will have varying timestamps based on when the rows were created in the source.

I disagree, I believe the answer is A) All rows loaded using a specific COPY statement will have varying timestamps based on when the rows were inserted.

Hold up, is this a trick question? What if the table has a trigger that updates the timestamp on every insert? Gotta be option A then!

I'm channeling my inner Sherlock Holmes for this one. Option C seems to be the logical choice - the timestamps should be based on the source data, not the load time.

This is a tricky one, but I'm leaning towards option D. Can't have varying timestamps if the default is a single function call, right?

I see your point, it does make sense that all rows loaded at the same time would have the same timestamp.

That's a good point, maybe option A would be more accurate then.

But wouldn't the timestamp be based on when the rows were inserted, not when they were created in the source?

I think you're right, option D seems to be the most logical choice.

Haha, the question says the default value is CURRENT_TIME() or CURRENT_TIMESTAMP(), so of course the timestamps will vary. I'm picking option B.

Definitely, the default values will give different timestamps. Option B is the way to go.

Yeah, the default values will result in varying timestamps. Option B makes the most sense.

I agree, the timestamps will definitely vary. Option B seems like the right choice.

I'm going with option A. The timestamps should vary based on when each row was inserted during the COPY operation.

Hmm, I think option D is the correct answer. All the rows loaded using a COPY statement should have the same timestamp value based on when the COPY statement was executed.
