Please create more videos. Very helpful
v good explanation 👌👌
Thanks for your feedback!!
Hi, you have used in trigger:
Trigger.operationType == triggerOperation.After_undelete? Is it constants class you have created?
Hi Sachin,
Trigger.operationType is the enum type(TriggerOperation) context variable which is available under Trigger class.
TriggerOperation is enum which has all the trigger operation types as values like 'BEFORE_INSERT', 'BEFORE_UPDATE'.....
I have explained this in first video of this series, please refer that for more updates..
@@forcefellow thank you
I'm new to salesforce.
Help me to understand better.
You created new lead record and assign the recycle bin record id to new lead record.
When you recover the deleted record you have one or two records?? or will it update the recycle bin record? But you said after update record is in read only mode. Pls clarify.
Delete means record has moved into recycle bin with all the details including record I'd.
And while undelete record will move back to the original object with same details.
Which means whole record is same while undelete including record I'd.
Hope now you understood. Connect me over below mail for more details -

Got it. 👍
@@forcefellow So basically when you created a new instance of lead , you overwrite that instance with undelete record values and ID ---> hence there is only 1 Bertha record in SF ...is this correct ?
Correct. Here we are performing update operation and record Id is same which we have undeleted, so only 1 record will be there in DB.
