i have a list of data which actually have duplicates, thus i will like to use
group by to group them together to prevent the duplicates. i'm grouping them
according to the id available. however, some data does not contain id num,so
when i do grp by, all data that does not have id will become one records. is
that anyway i can sort my data where duplicates records will become one
record and for those without id, it will just remain as what it is.
