Can be a zero-length string (i.e. empty path) if the outermost element is to be flattened. Default: Zero-length string (i.e. empty path) OUTER => TRUE | FALSE 1 Answer Sorted by: 0 The best answer I can think of using Snowflake SQL to do ARRAY_SIZE (OBJECT_KEYS (x)). However, this seems more complicated than it needs to be. For the special case of checking for empty OBJECT (cardinality 0), I could compare x = OBJECT_CONSTRUCT ().
