A developer has written an After Update trigger on Account. A workflow rule and field update cause the trigger to repeatedly update the Account records.
How should the developer handle the recursive trigger?

Which of the following about Dynamic Apex is incorrect?

A custom field Exec_Count_c of type Number is created on an Account object. An account record with value of "1" for a: Exec__Count_c is saved. A workflow field update is defined on the Exec_Count_c field, to increment its value every time an account record is created or updated. The following trigger is defined on the account:
trigger ExecOrderTrigger on Account (before insert, before update, after insert, after update){ for (Account accountlnstance: Trigger.New){ if (Trigger . isBefore){ accountlnstance Exec_Count_c += 1; } System, debug (accountlnstance.Exec_Count_c); } }
