Get All Object:-
Map<String, Schema.SObjectType>schemaMap=Schema.getGlobalDescribe(); for(SObjectType obj: schemaMap.values()){ if (obj.getDescribe().isCreateable() && obj.getDescribe().isUpdateable()) { System.debug('-->Object Name = '+obj.getDescribe().getLabel()); System.debug('-->Object API Name = '+obj.getDescribe().getName()); } }
Get Child Record From Inner Query Dynamically:-
List<Account> listOfAccount = [SELECT Id,Name,(SELECT Id,Name FROM Contacts) FROM Account LIMIT 1 ]; List<sObject> listOfChild = listOfAccount[0].getSObjects(childRelationshipName);

Related to Fields
Get All Field:-
Map<String, Schema.SObjectType> schemaMap=Schema.getGlobalDescribe(); Map<String,Schema.SObjectField> fieldMap=schemaMap.get(objectName).getDescribe().fields.getMap(); for(Schema.SObjectField obj : fieldMap.values()){ if(obj.getDescribe().isCreateable() && obj.getDescribe().isUpdateable()){ System.debug('--->Field Name ='+obj.getDescribe().getLabel()); System.debug('--->Field API Name ='+obj.getDescribe().getName()); } }
Get the Field Type:-
1. <String,Schema.SObjectField>objectFields=Schema.getGlobalDescribe().get(objectName).getDescribe().fields.getMap(); Schema.DescribeFieldResult fieldLabel = objectFields.get(fieldName).getDescribe(); Schema.DisplayType dataType = fieldLabel.getType(); String fieldType = String.ValueOf(dataType); System.debug('fieldType--> '+fieldType); 2. Map<String,Schema.SObjectField> objectFields=Schema.getGlobalDescribe().get(objectName).getDescribe().fields.getMap(); Schema.SObjectField field = objectFields.get(objectName); Schema.DisplayType fieldType = field.getDescribe().getType(); System.debug('...fieldType '+fieldType);
Related to Record Type
Get List Of All Record Types :-
Map<String,RecordTypeInfo> mapOfRecTypeInfo = Schema.getGlobalDescribe().get(objectName).getDescribe().getRecordTypeInfosByName(); for(String recInfo:mapOfRecTypeInfo.keySet()){ RecordTypeInfo recType = mapOfRecTypeInfo.get(recInfo); System.debug('==>Id'+recType.getRecordTypeId()); System.debug('==>Id'+recType.getName()); }
Get Record Type Id by Name:-
String recordTypeId= Schema.SObjectType.Account.getRecordTypeInfosByName().get(recordTypename).getRecordTypeId(); System.debug('--->recordTypeId '+recordTypeId);
