Execute SOQL On Chatter in Salesforce

Today I am providing a piece of code which will introduce a new way to run your simple SOQL on Chatter it self without opening developer console(that might take some time while loading).

To use this tool you just need to keep this trigger code in your org and then you can execute simple SOQL queries as follows.

Step1 : Post a SOQL in chatter on any object in the org.
Step2 : Refresh the screen you will get your result as below.

trigger ChatterAsConsole on FeedItem (after insert)
{   
    if(UtilClass.noOfExecution == 0)
    { 
        String queryString = '';  
        FeedItem post ; 
        for (FeedItem f: trigger.new)
        {  
            Try
            {                 
                //Adding a Text post
                post = new FeedItem();
                post.ParentId = f.ParentId; //eg. Opportunity id, custom objectid
                queryString = f.Body ;
                String idString = '';
                
                for(Sobject s : Database.query(queryString))
                {
                        idString += s.id+', ';
                }        
                if(idString.endsWith(', '))
                    idString = idString.substring(0,idString.length()-2);
                post.Body = idString ;
                UtilClass.noOfExecution ++ ;
                insert post;
            }catch(Exception e)
            {
                post = new FeedItem(ParentId = f.ParentId , Body  = e.getMessage() );
                insert post;
            }
        }
    }
}

Helper Class : 

public Class UtilClass
{
 public static Integer noOfExecution = 0; 
}

This code has its own limitation but you can customize it as per your need.

How to get Record Type Id without SOQL

Whenever we would like to fetch data from Database SOQL comes as first option in our mind but it will be added in query consumption limit. Here is a way to do this without any query:

// User need to pass two parameters SObject Type & 
    //RecordType Label ( not Record Type Developer Name)
    public static ID getRecordTypeId(String ObjectType, String RecordTypeLabel)
    { 
      SObject OBJ;
      // Describing Schema
      Schema.SObjectType Res = Schema.getGlobalDescribe().get(ObjectType);
      if (Res != null)
      {
  OBJ = Res.newSObject();
  // Describing Object 
  Schema.DescribeSObjectResult DesRes = OBJ.getSObjectType().getDescribe(); 
  if (DesRes != null)
  {
            Map RecordTypeMap =      DesRes.getRecordTypeInfosByName();
     if (RecordTypeMap != null) 
     {
        Schema.RecordTypeInfo RecordTypeRes = RecordTypeMap.get(RecordTypeLabel);
        if (RecordTypeRes != null) 
        {
           return RecordTypeRes.getRecordTypeId();
        }
      }
   }
        }
 return null;
    } 

Let's say there are two Record Type of Account so we can get Record Type ID of Account Like this

ID RecordTypeId = getRecordTypeId('Account' , 'RecordType1');
