java.lang.Object

dev.frostlake.executor.FileFormatReference

public final class FileFormatReference
extends Object

A FILE_FORMAT that names a file format. Every spelling that gives a NAME rather than a TYPE reaches the same refusal on a real account when nothing holds the name - a bare word, a string literal and FORMAT_NAME = … alike, on CREATE STAGE, ALTER STAGE and COPY INTO:

   SQL compilation error:
   File format 'NOSUCHFORMAT' does not exist or not authorized.
 

A bare word is a NAME, not a type: FILE_FORMAT = CSV is refused unless a file format called CSV exists, where FILE_FORMAT = (TYPE = CSV) declares the type and needs nothing. A qualified name is echoed in full. The check comes before existence is answered, so CREATE STAGE IF NOT EXISTS over a stage that already stands still refuses (live-verified).
