Answer: An empty string

According to Snowflake's official documentation for the SPLIT_PART function, when the partNumber parameter is out of range (either greater than the number of parts or less than 1), the function returns an empty string. This is explicitly stated in the usage notes section of the documentation. The community discussion strongly supports this with 80% of users selecting option B, and multiple comments citing the official documentation that confirms this behavior. Option C (the full string) is incorrect as that would only occur in specific scenarios like when the delimiter is not found, not when partNumber is out of range. Option A (-1) and Option D (an error) are also incorrect as the function is designed to handle out-of-range part numbers gracefully by returning an empty string rather than throwing an error or returning a numeric value.
