@sanjay Gupta Thanks you sir ❤🎉 but aap agar thoda Hindi language used krke samjhauge to aur better samjhega 😊😅

It's complicated to understand

Thank you for creating this useful video. For the AfterDelete use case, I believe we can use Aggregate Queries to simplify the code further.

Sir, pls remove this video lot of confusion in this scenario. U could have done a lot better than this explanation

}

Method

{
set<id> s1 = new set<id>();
list<contact> c2 = new list<contact>();
for(contact c3 : c1)
{
if(c3.AccountId != null)
{
s1.add(c3.accountid);
c2.add(c3);
}
}
list<account> a1 = [select left_contact__c from account where id in :s1];
for(account a2 : a1)
{
for(contact c4 : c2)
{
if(a2.id==c4.accountid)
{
if(a2.left_contact__c==null)
{
a2.left_contact__c = 0;
