When using the copy into

command with the CSV file format, how does the match_by_column_name parameter behave?

Show Suggested AnswerHide Answer
Suggested Answer: D

When a new table (table_6) is added to a schema in the provider's account that is part of a data share, the consumer will not automatically see the new table. The consumer will only be able to access the new table once the appropriate privileges are granted by the provider. The correct process, as outlined in option D, involves using the provider's ACCOUNTADMIN role to grant USAGE privileges on the database and schema, followed by SELECT privileges on the new table, specifically to the share that includes the consumer's database. This ensures that the consumer account can access the new table under the established data sharing setup. Reference:

It needs a header in the CSV, totally case-sensitive!

I think the match_by_column_name parameter requires a header in the CSV file, but I'm not sure if it's case-sensitive.

I'm feeling pretty confident about this one. The parameter expects a header in the CSV file, and the column names need to match the table column names. I'll select option A.

Okay, I've got a strategy for this. The key is understanding how the match_by_column_name parameter works. I'll review the documentation and then make my best guess.
