// Collect all Account IDs from the trigger Set accountIds = new Set(); for (Account acc : Trigger.new) { accountIds.add(acc.Id); } // Query all Contacts related to the Accounts in the trigger List conList = [SELECT Id, AccountId FROM Contact WHERE AccountId IN :accountIds]; // Process each Contact for (Contact con : conList) { // Your logic here }

1. DML Exception - Required Field Missing (LastName) 2. QueryException - No records returned or trying to assign more than 1 record to a singleton sObject Account variable.

[@TechJourneyWithAnkit]

Correct

[@kaustubhpatne6320]

In 1st scenario Where you iterate over accounts Mistake is that Dml statement used inside for loop So to overcome this use separate list and insert list outside for loop

[@TechJourneyWithAnkit]

Very good

It may throw the query exception. More than one record to a singleton sObject variable.

[@janac7510]

Nice

[@awesomekj5812]

Curious ..have you done the video on Apex Replay Debugger ? Also for last question --> will you get LIST HAS NO ROWS FOR ASSIGNMENT TO SObject error ??? And we can fix it by converting that account instance to List

[@TechJourneyWithAnkit]

Not yet, will plan for it.

[@vaibhavchaubey4748]

required field is missing in last question , cont.LastName

[@TechJourneyWithAnkit]

Please tell me the name of exception
