Explanation

Snowflake's COPY INTO command supports a VALIDATION_MODE parameter that allows you to validate the data processing without actually performing the operation. For unloading, specifying VALIDATION_MODE causes Snowflake to check for errors and return diagnostic information rather than writing output files. Options such as RETURN_ERRORS or RETURN_ALL_ERRORS surface any issues with the data or transformation. This is a dry-run mechanism - no files are written, no data is moved - making it the correct approach to validate the unload operation before committing it.
