Subj:   Order of Records in Source file for MLOAD

Hi,

If a source file has more than one record with same primary index (unique) value, what happens when an UPSERT MLOAD is run to load this file into a teradata table (with unique primary index)?.

Will the first record (as per the sequence in the file) be INSERTED (assuming the table did not have the record before) and will the second record update the just INSERTED record ? If yes, where does this UPDATE happen; in the WORK table before applying to target table or while applying to the target table ?


Thanks and Regards
