how can you know which record is the duplicate and which record is the original one?

| What you mentioned is right .We dont have distinction between original and duplicates.My basic requiremnt is to find out whether any name in this table has the same start values or stop values as others. |

Not sure but try this:select * from YourTable where start in (select start from YourTable group by start having count * > 1)or stop in (select stop from YourTable group by stop having count * > 1)

The problem is: we are on MS SQL Sever only in these forums. You are using MySQL and I don't know what is possible in MySQL.Maybe you can get better help in http://www.dbforums.com/mysql/Sorry
