trigger to insert, update and delete records in contact when account is created

Suraj Tripathi 47Suraj Tripathi 47

Hi Akshata,

I am giving you a sample of the code. You can take references from it.

Case 1: Insert

trigger InsertContact on Account (after insert)
{
    List <Contact> cntLst = new List<Contact>();
        for(Account acc: Trigger.New)
        {
            Contact cnt = new Contact();
            cnt.LastName = 'chirag'+''+ acc.name;
             cnt.AccountId=acc.id;
            cntLst.Add(cnt);
         }
             insert cntLst;
}


Case 2: Update 

trigger accountcontat on Account (after update){
   List<Contact> contactList = new List<Contact>();
   List<Contact> contactList1 = new List<Contact>();
for(Account acc: [SELECT Id,(SELECT Id,checkbox__c FROM Contacts) FROM Account WHERE Id in: Trigger.new]){
   If(acc.Contacts.size()>0){
     contactList.addAll(acc.Contacts);
    }
}
for(contact c:contactList){
       c.checkbox__c=true;
       contactList1.add(c);
}
update contactList1;
}

Case 3: Delete

trigger deleteAccountRecord on Contact (after delete) {


    RecordType donorRecType = [SELECT ID FROM RecordType WHERE sObjectType = 'Contact' AND DeveloperName = 'Donor_Contact'];
    if(Trigger.isDelete){
        List<ID> accIds = new List<ID>();
        for(Contact contactToDelete: Trigger.old) {
            if (contactToDelete.RecordTypeId != donorRecType.Id ) {
                  
                    contactIDList.add(contactToDelete.AccountId);
            }
        }
      
       
       List<Account> DelAccountRecordList = [select id from Account where Id IN:accIds];

        if(DelAccountRecordList.size() >0){
           delete DelAccountRecordList ;
         
        }
     }
  }

Hii Akshata
Try Below Code 
trigger AccountRElatedContact on Account (After insert, After update,Before delete) {
    Set<Id> lstIds = new Set<Id>();
    list<Account>lstAcc=new list<Account>();
    if (trigger.isAfter && trigger.IsInsert) {
        for (Account Acc : trigger.new) {
            Contact Con = new Contact();
            Con.FirstName = Acc.Name;
            Con.LastName = 'Test';
            Con.AccountId = Acc.Id;
            Insert Con;
        }
    }
    if (trigger.isAfter && trigger.IsUpdate) {
        for (Account Acc : trigger.new) {
            if(Acc.Name != Trigger.oldMap.get(Acc.Id).Name){
                lstIds.Add(Acc.Id);
            }
        }
    }
    if (trigger.isBefore && trigger.IsDelete) {
        for (Account Acc : trigger.old) {   
                lstIds.Add(Acc.Id);  
        }
    }
    
	for(Account acc :[Select Id,Name,(Select id,FirstName,LastName from Contacts) from Account where Id IN : lstIds]);	
    string Name = Acc.name;
        for(Contact Con : acc.Contacts){ 
			Con.FirstName = Name;
            lstCon.Add(Con);
        }
    lstAcc.Add(Acc);
    }
    if(lstAcc.size()>0){
        update lstAcc;     
    }

	if (trigger.isBefore && trigger.IsDelete) {
        list<Contact> lstConDelete = [Select id,FirstName,LastName,AccountId from Contact Where AccountId IN:lstIds];
        if(lstConDelete.size()>0){
            delete lstConDelete;
        }
	}

}

Hi,

Trigger:

trigger InsertContact on Account (after undelete, before delete,After Insert,After Update,before insert,before update)
{

if(Trigger.isAfter && trigger.isInsert) {
	  data.createData(trigger.new);
}else if(Trigger.isAfter && trigger.isUpdate){
     data.updateData(trigger.new);
}else if(Trigger.isAfter && trigger.isDelete){
       data.deleteData(trigger.old);
}
 
}


Helper class:

public class data{

 public static void createData(List<Account> newAccountList){
 
 List <Contact> cntLst = new List<Contact>();
        for(Account acc: newAccountList)
        {
            Contact cnt = new Contact();
            cnt.LastName = 'chirag'+''+ acc.name;
             cnt.AccountId=acc.id;
            cntLst.Add(cnt);
         }
             insert cntLst;
 
 }




 public static void updateData(List<Account> newAccountList){
 List<Contact> contactList = new List<Contact>();
   List<Contact> contactList1 = new List<Contact>();
for(Account acc: [SELECT Id,(SELECT Id,checkbox__c FROM Contacts) FROM Account WHERE Id in: newAccountList]){
   If(acc.Contacts.size()>0){
     contactList.addAll(acc.Contacts);
    }
}
for(contact c:contactList){
       c.checkbox__c=true;
       contactList1.add(c);
}
update contactList1;
 }



 public static void deleteData(List<Account> oldAccountList){
 RecordType donorRecType = [SELECT ID FROM RecordType WHERE sObjectType = 'Contact' AND DeveloperName = 'Donor_Contact'];
    
        List<ID> accIds = new List<ID>();
        for(Contact contactToDelete: oldAccountList) {
            if (contactToDelete.RecordTypeId != donorRecType.Id ) {
                  
                    contactIDList.add(contactToDelete.AccountId);
            }
        }
      
       
       List<Account> DelAccountRecordList = [select id from Account where Id IN:accIds];

        if(DelAccountRecordList.size() >0){
           delete DelAccountRecordList ;
         
        }
 }

 }
