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?

Show Suggested Answer Hide 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.

* Community article on recognizing unsatisfactory pruning and improving it1

D is definitely a possibility, return_all_errors can be tricky.

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.
