I have a dataset with about 20-50 records on it. Some of has the same value
for a key column, those duplicates need to be removed.
How can I remove duplicate itmes from a dataset????
I know some poeple will tell me to use GROUP BY and DISTINCE to filter out
duplicates in SQL, but in my case, I am not able to do this!
Any help?
