Snowflake ARA-C01 Exam - Topic 6 Question 24 Discussion

Actual exam question for Snowflake's ARA-C01 exam

Question #: 24
Topic #: 6

Consider the following COPY command which is loading data with CSV format into a Snowflake table from an internal stage through a data transformation query.

This command results in the following error:

SQL compilation error: invalid parameter 'validation_mode'

Assuming the syntax is correct, what is the cause of this error?

AThe VALIDATION_MODE parameter supports COPY statements that load data from external stages only.

BThe VALIDATION_MODE parameter does not support COPY statements with CSV file formats.

CThe VALIDATION_MODE parameter does not support COPY statements that transform data during a load.

DThe value return_all_errors of the option VALIDATION_MODE is causing a compilation error.

Show Suggested Answer

Suggested Answer: C

Effective pruning in Snowflake relies on the organization of data within micro-partitions. By using an ORDER BY clause with clustering keys when loading data into the reporting tables, Snowflake can better organize the data within micro-partitions. This organization allows Snowflake to skip over irrelevant micro-partitions during a query, thus improving query performance and reducing the amount of data scanned12.

D is definitely a possibility, return_all_errors can be tricky.

Wait, I thought VALIDATION_MODE was universal? This is surprising!

C sounds right to me, transformations can mess things up.

I disagree, I think B makes more sense. CSV should be fine.

A is correct! VALIDATION_MODE only works with external stages.

I wonder if the error could be related to the specific value 'return_all_errors' in option D. That seems like a possible source of the problem.

I think we had a practice question about transformation queries causing issues with COPY commands. That makes me lean towards option C.

I'm not entirely sure, but I feel like we discussed how CSV formats should work with validation modes. Maybe option B is misleading?

I remember reading that the VALIDATION_MODE parameter is specific to external stages, so I think option A might be correct.

Aha, I think I see the problem. The 'return_all_errors' value for VALIDATION_MODE is likely causing the compilation error. I'll try a different value for that parameter and see if that resolves the issue.

Wait, I'm a bit confused. The question says the syntax is correct, so the issue must be something else. Maybe the VALIDATION_MODE parameter just isn't supported for CSV file formats or data transformations. I'll need to review the documentation to be sure.

Alright, I think I've got this. The VALIDATION_MODE parameter is only supported for COPY statements that load data from external stages, not internal stages like this one. That must be the cause of the error.

Okay, let's see. The error says the 'validation_mode' parameter is invalid, so that's clearly the issue. I'll need to double-check the valid options for that parameter.

return_all_errors, huh? Sounds like a recipe for a comedy of errors. I bet the engineers at Snowflake are just chuckling away at this one.

Wait, so they're trying to transform the data while loading it? That's a bold move, Cotton. Let's see if it pays off for them.

Hmm, I'm stumped. Validation mode is usually for external stages, but this is an internal stage. Guess I'll have to dig deeper to figure out what's going on here.
