What have you tried? What does your data look like? What is the output that you get when you run your query? What does the output look like that you want to get?

Hi, you can use a statement with Group and Having clause to find duplicates:

SQL

Select Name, Count(Name) as Cnt from voters
Group by Name
Having Count(Name) > 1
