How can you update Salesforce record using Apex, when you don’t know Object API name, but you know record Id ?

Using Dynamic Apex we can achieve this :

view source

print?

1	//Lets assume this is record Id

2	Id recId = 'a0P9000000ESXcV';

3

4	Schema.SObjectType token = recId.getSObjectType();

5	Sobject s = token.newSobject();

6	s.put('Id',recId );

7	s.put('Name', 'om');

8

update s;
