Hi Rahul,

 

Here is code which hopefully will resolve your problem :

 

 

List<AggregateResult> AG = [select name N from account group by name] ;
String NameString = '' ;
for(AggregateResult A : ag)
{
    if(NameString == '')
         NameString += A.get('N') ;
   else
         NameString += ' , ' + A.get('N') ;
}
System.Debug('NameString :::::::::::::::: ' + NameString) ;

 

Thanks

Hi Ankit,

 

    Thanks for sending the code.  The Code which you have send is getting complied successfully in Apex class, but when I am trying to display the Plot_Area field Venture object on the Visualforce page I am getting the following error message.

 

 

Attempt to de-reference a null object

 

 

An unexpected error has occurred. Your development organization has been notified.     

 

 

I am posting the code, could you please look into it and provide a better solution.

 

 

 

 

List<AggregateResult> AG = [select sum(plot_area__c) N from plot__c where plot_status__c = 'sold'];

String NameString = '' ;
for(AggregateResult A : ag)
{
    if(NameString == '')
         NameString += A.get('N') ;
   else
         NameString += ' , ' + A.get('N') ;
}
System.Debug('NameString :::::::::::::::: ' + NameString) ;
v.Plot_Area__c=NameString;
update v;

 

 

 

Actually I have a requirement, where in I need to calculate the sum of the Plot_Area field from the Plots Object and convert it to text in Plot_area field of Venture Object.  Could you please send the solution.    

 

 

Thanks and Regards

 

Rahul

Please let me know if you are getting proper values in debug System.Debug('NameString :::::::::::::::: ' + NameString) ; ?

Also error occurs where in code , when you update the object? If error occur where you updating the object then there must be some problem within the creation of instance of object.

 

Thanks
