Question

An Architect runs the following SQL query:

How can this query be interpreted?

Exhibit

Options

AFILEROWS is a stage. FILE_ROW_NUMBER is line number in file.
BFILEROWS is the table. FILE_ROW_NUMBER is the line number in the table.
CFILEROWS is a file. FILE_ROW_NUMBER is the file format location.
DFILERONS is the file format location. FILE_ROW_NUMBER is a stage.

Explanation

In Snowflake, when querying data from an external or internal stage, FILEROWS refers to a stage alias (the source of the files being read). FILE_ROW_NUMBER is a Snowflake metadata column (accessed via METADATA$FILE_ROW_NUMBER) that returns the sequential line number of each record within its source file - not the row number in a table. This metadata is useful for debugging data load issues, identifying which specific line in a source file caused an error, and validating file parsing. Option B is incorrect because FILEROWS is not a table. Option C is incorrect because FILE_ROW_NUMBER is not a file format location. Option D is incorrectly swapping the definitions of both identifiers.
