[@aslambagwan6032]

[@asish681]

Thanks for the video.. It's really helpful

[@SanjayGuptaTechSchool]

Thank you 🙏

[@ShivamSangam-re6qn]

I am in Salesforce domain from last 1 year but i never touch code yesterday my TL assigned me one task and I just gone through your 1-2 basic videos and 2-3 scenario videos ,now most of the things are crystal clear.. A big thanx to you 😊

[@SanjayGuptaTechSchool]

Glad that videos helped you to understand the concepts.

[@kguliyev1998]

Hello Sanjay. I have a question. Instead of initiating a new Contact record (conRec) inside the loop, and assigning the values to that, can't we just update the current Contact, and then update the conList at the end (instead of updating 'consToBeUpdated)? As following:
con.Phone = accIdToAccountMap.get(con.AccountId).Phone
This way we wouldn't need to create a new contact list and initiate a new contact record. Thank you

[@SanjayGuptaTechSchool]

Just test this way as well if it works then perfectly fine.

[@kguliyev1998]

@@SanjayGuptaTechSchool Thank you for the reply. I just ran this way, and it works.

[@nehajamdade2983]

We are already fetching contacts from account map then why to check again contains key condition at line 20 11:35 ? Is it necessary

[@SanjayGuptaTechSchool]

Yes we can skip that condition but i just used it to show how to check keys available in map or not.

[@shivakumarreddyp8764]

Bro create playlist for this so that we can access easily

[@nowsathkhana533]

Sorry , not understand this.. why are we adding a comRec in a loop, and y create
List contact conList = new List contact();
Shall we directly call con phone replace acc phone ... Explain

[@SanjayGuptaTechSchool]

Actually we cannot perform DML operations in loop so we are creating a list and after completion of loop we can apply dml on list.
