sathya_sam3 Access sobject field which is defined dynamically
Hi I have a custom setting(CS) field where am saving a SOQL Query. I am passing this query thru the CS field to a global SOBJECT. Now I want to access the field in the sObject which was predefined in the Query.
Query saved in CustomSetting: "login_cred " field "Soqlogin" = "SELECT Id,Registration_Approved__c,SiteProfile__c,SiteProfile__r.Name__c,SiteProfile__r.Default_Home_Page__r.Name__c FROM Contact WHERE UserName__c = username.toLowerCase() AND Password__C = :password "
global static SObject currentContact;
List<login_cred__c> logcredlist =[SELECT soqlogin__c FROM login_cred__c LIMIT 1];
string logcred = logcredlist[0].soqlogin__c;
currentContact = Database.query(logcred);
String profileName = currentContact.SiteProfile__r.Name__c;
Here am getting an error something like :"Save error: Field expression not allowed for generic SObject "
Thanks in advance.

To ger relationship field from generic sObject like this -
SObject c = Database.query('SELECT Id, FirstName, AccountId, Account.Name FROM Contact LIMIT 1'); String accountName = String.valueOf(c.getSObject('Account').get('Name')); System.debug(accountName);With custom relationships you'd use soemthing similar to:
s.getSObject('Your_Custom_Object__r').('Some_Field__c')

Thats correct! You can not access fields directly using sObject. You can typecast it or use sobject method get() to retrieve the value.
For your code, I can not see any specific reason to use sObject. You can directly use Contact type.
for example
global static Contact currentContact;
Try it and let us know if it helps.
NOTE: If you want to use sObject then You can not get values of relationship fields using sObject get method. i.e. currentContact.get('Registration_Approved__c') will work but currentContact.get('SiteProfile__r.Name__c') will not work.
Cheers!
Thanku crmtech21.
Now am stuck up with the same. I am getting the direct field. but am not getting the value of relationship field in SObject :"CurrentContact" ..... i want to access the relationship field. Is there any other way?
And i can't Use Contact directly as i want it to be a variable and change it to another object in future whenever I want from Custom Settings.
