The correct answer is A. GET_RELATIVE_PATH .
The GET_RELATIVE_PATH function is used to return the relative path of a staged file. The relative path identifies the file name and path of the file within the stage.
Why A is correct:
A file stored in a stage can be referenced by its relative path. GET_RELATIVE_PATH retrieves that relative path, which includes the file name.
Why the other options are incorrect:
B. GET_STAGE_LOCATION returns the URL or location of a stage, not the filename of a specific staged file.
C. BUILD_STAGE_FILE_URL creates a URL for accessing a staged file, but it is not used simply to retrieve the filename.
D. GET_OBJECT_REFERENCES is related to object references, not staged file names.
Official Snowflake documentation reference:
Snowflake documentation describes GET_RELATIVE_PATH as a function that returns the relative path for a staged file.
