i have a table called memebrs which consist of memberid(Autogenerated), First name, lastname, dob, and so on...

but since user clicked twice or thrice during registration the Recoreds are duplicated..

now i want to remove duplicated record based on comparing
firstname,lastname,dob,and palce...

i cannot compare all fields because even if the records are same there are two fields unique one is Autoincrementing serialnumber and Php auto generated Memberid

so someone please help me to solve this problem
thank you....
