HI ,
I have written written apex class to create a case and return a case by Id using REST API and JSON.I am not sure how to use REST API to update a Case record by passing the the updated value in JSON format. For instance if I want to update the priority of an existing case from High to Low. Can somebody help on this?


-------------------------------------------
@RestResource(urlMapping='/Case/*')

global with sharing class CaseCreater {
 @HttpGet
    global static Case getCaseById() {
        RestRequest req = RestContext.request;        
            String caseId = req.requestURI.substring(
                                      req.requestURI.lastIndexOf('/')+1);
        Case result =
                       [SELECT  Status,Origin from Case where  Id = :caseId];
        return result;
    }
    @HttpPost
    global static String createCase(String priority,String type, String status,
        String origin,String reason, String subject, String description ) {
        Case c = new Case(
         
            Priority=priority,
            Type= type,            
            Status=status,
            Origin=origin,
            Reason=reason,
            Subject=subject,
            Description=description          
                            );
        insert c;
        return c.Id;
    }
}
//SELECT  Status,Origin,priority,Product__c,Type,Reason,
//Subject,Description,account.name,case.contact.name from Case where status='New'

 

Any idea on how to display two tables on a vf page and compare each row of the two tables and display the output as matched or not matched on click of a button ?In the second table there should be a flag column that should be updated with true or false if any of the rows from two table match.

Thanks

I have developed a Visualforce page which contains two dropdownsWill show all Objects in my organisation.
​Will show all fields based on selection of objects.​I can multiselect fields from second dropdown, and a SELECT query is generated.
I have fetched all deatil records of those fields but I am not able to display those records on Visualforce Page as the data is Dynamic, every time you choose different object their corresponding fileds I need to display different columns,thier records. 
Please help me to sort this problem.
