How to write a trigger to count records based on particular field & storing the count value in another field?

Prashant Pandey07Prashant Pandey07
Hi Thulasi,

Check this example http://developer.salesforce.com/forums/?id=9060G0000005OKkQAM  (http://developer.salesforce.com/forums/?id=9060G0000005OKkQAM )

or let me know if you have a specific situation where you would like to count the record.

If you are using a master/detail relationship I would first suggest rollup fields

I have the task of counting how many Events per user, per month have a checkbox (Request Meeting Bonus) selected. How can this be done? That number will determine the amount Bonus_MR__c is per user. That part should be easily done with a process or workflow. My main problem is calulating the number of Requests.

Hi,

You can check this code..Here I'm updated the user Total_Request_Meeting_Bonus__c fields based on number of events which has Request_Meeting_Bonus__c true
Note-  I have not compiled this code
  
trigger Counteventon event(after insert, after update) {
    
    public List<ecent> ltask1 = new List<event>();
    public id userids;
    public integer inp=0;   
    public integer inr=0;
    for(event t:Trigger.New){
        userids = t.WhatId;
      
        
    }
	ltask1 = [select id,Requested_meeting_bonus__c from task where whatid=:oppid];

    
    
    for(event t:ltask1){
        if(t.Requested_meeting_bonus__c==true){
            inp = inp+1;
        } else{
            inr = inr +1;
        }                
    }
    List<user> uopp = new List<user>();	
    List<user> userop = [select id from user where id = :userids];

    for(user u: userop){
        u.Total_Requested_meeting_bonus__c = inp;
    
        uopp.add(u);  
    }
    if(uopp.size()>0){
    	update uopp;
	}        
 
}

Error: Compile Error: Variable does not exist: oppid at line 12 column 76 ltask1 = [select id,Requested_meeting_bonus__c from task where whatid=:oppid]; Best, Angie

Update the line 8 and 12

userids = t.ownerid;

ltask1 = [select id,Requested_meeting_bonus__c from event where ownerid=:userids];

One more question; how to reset this at a new calendar month?
 
Prashant Pandey07Prashant Pandey07
@Angela,
You can try something like this and update the line 12

Date startOfMonth = Date.today().toStartOfMonth();
Date startOfNextMonth = startOfMonth.addMonths(1);

ltask1 = [select id,Requested_meeting_bonus__c from event where ownerid=:userids where CreatedDate >= :startOfMonth AND                                                                                                                                            CreatedDate < :startOfNextMonth];
