Where 'VALUE' is the common value of your fields that you want to be deleted.

I meant I want to find all the entries which are repeatimg anddelete them keepimg one copy. I dont want to enter the syntax for each and every name
You don't want to have duplicate names ? Then modify field types. Make them Unique or Index. That way when you try to insert the same value again, you will get an error and your database won't be redundant.
That's a good question..
Primary it's used for indexing if you plan to select frequent amount of data based on that field match.
Judging by the purpose of the field you should use unique but you still have no primary field. I would go with primary.
