code should be like this:
Check whether the pk is present, if present, its a duplicate record.
then check for the null values
then check for invalid date columns
iif(not isnull(pk),error_code_dup_rec,
iif(isnull(col1)
or (is null(col2),null_value_
present,
or is null(date),invalid_date,valid_record))
