Selected Answer: A
You can use the OBJECT_CONSTRUCT function combined with the COPY command to convert the rows in a relational table to a single VARIANT column and unload the rows into a file.

Hence answer B. It doesn't specify file compression in the statement.

Agree, it's A. Because it's copy into @message from (select object_construct('id', 1, 'first_name', 'Snowflake', 'last_name', 'User', 'city', 'Bozeman')) file_format = (type = json) It has only 1 row here.

Selected Answer: B
OBJECT_CONSTRUCT function combined with the COPY command to convert the rows in a relational table to a single VARIANT. The question is a single or multiple files. The compression bof data is by defaut. So it's between A and B but since the parameter SINGLE=TRUE is not sprecified, shouldn't the answer be multiple compressed files hence B?
