How to delete duplicate records in Salesforce?

Hi Ankit,

How you identify that the record was duplicate.  Can you please explain more on that.

Hello Ankit,

If you consider duplicate's in terms of name or any particular field of any object might be the below code would be helpful to get your answer. I tried below code to remove duplicate name records of Accounts object.

List<Account> fullList = [Select Id, name From Account limit 200];
Set<String> orderObj = new Set<String>(); 
List<Account> dupList = new List<Account>();

for(Account a : fullList)
{
 if(orderObj.contains(a.name))
 {
 dupList.add(a);
 }
 else
 {
 orderObj.add(a.name);
 }
}

delete dupList;

Hope the answer would be helpful!!
