While running the following query it returns only one duplicate account name but not all the accounts that has the same name.How to get other matching duplicate names?

acc = [SELECT Name,count(id),AccountNumber FROM Account GROUP BY Name,AccountNumber HAVING count(Name)>1];

Result while adding inner loops:

   Set<String> duplicateNames = new Set<String>();
Public DuplicateAccNames()
acc = [SELECT Name,count(id) FROM  Account group by Name having  count(Name)>1];
System.debug('acc count'+acc);
//acc = [select  id,Name,AccountNumber, Phone from Account group by id,name,AccountNumber,Phone having count(Name)>1 ];
for(AggregateResult ac1 : acc)
List<Account> duplicates = [SELECT Name, AccountNumber
    FROM Account
    WHERE Name IN :duplicateNames];

enter image description here


Right now, you're getting a List<AggregateResult>. You need a List<Account> if you want to see the individual records. Probably the simplest way to take what you have already and get what you want is to collect a Set<String> duplicateNames then add another query.

Set<String> duplicateNames = new Set<String>();
for (AggregateResult aggregate : [/*existing query*/])
for (Account account : [
    SELECT Name, AccountNumber
    FROM Account
    WHERE Name IN :duplicateNames

    And we have to do this because we can't do: select id, name from account where name in (select name from account group by name having count(id) > 1). Silly SOQL. – sfdcfox Aug 16 '16 at 17:33
  • @sfdcfox Yeah added flexibility on inner-joins would be slick. But it would probably still have to be on indexed fields for performance reasons. I wonder if there's an Idea out there for that. – Adrian Larson Aug 16 '16 at 17:34
  • Nope@adrian and sfdcfox,.Its still returning only the count expr0 as 2 but not both the names – Priyalakshmi Aug 16 '16 at 17:55
  • You need to look at the List<Account>, which doesn't use count or GROUP BY or HAVING. You won't get individual records when you use aggregation. – Adrian Larson Aug 16 '16 at 17:57
  • Yeah but its returning multiple account Names instead of 4.I have update my Question – Priyalakshmi Aug 16 '16 at 18:09

Does this work for you ?

SELECT Name,count(id),AccountNumber FROM Account GROUP BY CUBE( Name,AccountNumber) HAVING count(Name)>1

List<AggregateResult> aggregate =   [SELECT Name,count(id),AccountNumber FROM Account GROUP BY CUBE( Name,AccountNumber) HAVING count( Name)>1 ];
system.debug ((string)aggregate[0].get('AccountNumber'));
