Need help eliminating duplicates and keeping the last record
Need a SQL statement that eliminates duplicates and chooses the last record entered.
Ex. WO1002421 has two entries. I want to keep the record of the last person Wilmer Tamayo-Sanchez.
This statement below is what I am using but as unfortunately, it still brings in duplicates.

How do you define "last one"? Typically, there is a date field or something like that to order by to determine which one is first or last.
