How to delete all duplicate records from SQL Table?

Question

Hello I have table name FriendsData that contains duplicate records as shown below

fID UserID  FriendsID       IsSpecial      CreatedBy
---         


        

Answer 1

Try this query,

  select * from FriendsData f1, FriendsData f2
  Where f1.fID=f2.fID and f1.UserID  =f2.UserID  and f1.FriendsID  =f2.FriendsID

If it returns you the duplicate rows, then replace Select * by "Delete"

that will solve your problem
