List<Schema.SObjectType> gd = Schema.getGlobalDescribe().Values();

Map<String,String> objectMap = new Map<String,String>();
for(Schema.SObjectType f : gd)
{
     objectMap.put(f.getDescribe().getKeyPrefix(), f.getDescribe().getName()));
}

 

ID sampleId ="a0190000003LIVw";

 

String prefix = sampleId.split(0,3);

 

String objectName = objectMap.get(prefix);

 

Map<String, Schema.SObjectField> desResult = Schema.getGlobalDescribe().get(objectName).getDescribe().Fields.getMap();


List<String> fieldList = new List<String>();


fieldList.addAll(desResult.keySet());


for(integer i =0;i<fieldList.size();i++)
    System.debug(fieldList[i]);

For the getting the the object name

 

List<Schema.SObjectType> gd = Schema.getGlobalDescribe().Values();

Map<String,String> objectMap = new Map<String,String>();
for(Schema.SObjectType f : gd)
{
     objectMap.put(,f.getDescribe().getKeyPrefix(), f.getDescribe().getName()));
}

 

ID sampleId ="a0190000003LIVw";

 

String prefix = sampleId.split(0,3);

 

String objectName = objectMap.get(prefix);

 

Similary  you can get the fields of the object and then query it

Schema.DescribeFieldResult F = Account.AccountNumber.getDescribe();

        For Query

 

RecordType rt = [SELECT Id,Name FROM RecordType WHERE SobjectType='Account' LIMIT 1];

 objectMap.put(,f.getDescribe().getKeyPrefix(), f.getDescribe().getName()));

 

comma is present after opening parenthesis. For getting field I've posted the code in previous reply

how can i write a query to  display the cureent account record details.

By using the Sobject.

 
Gunners_23Gunners_23

Cont from Previous

 

Below we're creating a Query

 

String Query = 'SELECT ';
for(integer i =0;i<fieldList.size();i++)
    Query += fieldList.get(i) + ',';

Query = Query.subString(0,Query.length()-1);

Query += ' FROM ' + objectName;

 

Now to run Query use Database.Query

 

List<Account> listAccount = Database.Query(Query);

 

Note i've used List<Account> you can't define  something like List<objectName>. So before running the Query determine the object type

If i want  to retrive only one Record. not list.that to only the current record am getting all the Record

how can i do it
