Hi AdmiralRonton,

The only option available at this time is the one presented in the tech note.

can i ask...
if i am looking to find out if a task belongs to a lead or a contact how exactly to i code that...
?

Well i found something a User poited out on ideas, HE SAID:

"[Select Who.name from task where id = :taskid];

Polymorphic relationships like who and what on task/event or owner on queue-ownable objects can be traversed. The object that is returned is called "Name". Here's the information you can access through this traversal:

(from the enterprise WSDL)
Alias
FirstName
LastName
Name
Type
UserRole
UserRoleId
"

But i could not understand how I could read these columns in APEX class?
My query is like this:
Select Subject,WhoId,WhatId,Who.FirstName,Who.Name,Who.type,What.type From task

Now i get a Collection NAME here which contains (FirstName,Name,Type), but how I could read these Values in APEX class? Any idea ?

you can use prefixes like this:

 

String contact_prefix = Schema.SObjectType.Contact.getKeyPrefix();

 

 

 

 

enjoy it ....

 

Thanks. Yes that would also work.

what tech note are you referring to?  the URL in the previous post is dead... please let us know!!!

The best way is to query for the type when you query for the Id, e.g.

 

select id, subject, who.id, who.type from Task

 

oh thanks, i ended up doing what another user posted and it worked!

 

 

if(ta.WhatId != null){

String account_prefix = Schema.SObjectType.Account.getKeyPrefix();

String task_whatid = ta.WhatId;

System.debug('who: ' + ta.WhoId + ' what: ' + ta.WhatId + ' prefix: ' + account_prefix + ' eval: ' + task_whatid.startsWith(account_prefix) + ' id: ' + ta.id );

 

if(task_whatid.startsWith(account_prefix)){
