Delete duplicate rows

Question

I have a table that looks like this

Table1

Id, Name

How can I write a query that delete all rows with duplicate names but kee

Answer 1

The duplicates can be removed with a simple self join query. The below script would do the trick for you.

delete t2
from Table1 t1
join Table1 t2
   on t1.Name = t2.Name
where t1.Id < t2.Id

This logic can be used for cases where duplicates need to be removed. We should avoid "cursor" as much as possible as it blocks the table.
