Trigger to check duplicate name to custom object in Salesforce
Hey guys, today in this post we are going to learn about How can we prevent duplicate name insert on custom object in Salesforce.
Real time scenarios:- Write a trigger on custom object When a Object (childObjTrigger__c) is being created, if a record exists with the same EmployeeName (EmployeeName__c), the trigger should throw an error.
Create a custom object with custom field name as EmployeeName
Custom Object:- childObjTrigger__c >> custom field:- EmployeeName__c (Text
type)
Files we used in this post example:-
childTriggerhandler.apxt

childObjHandler.apxc
Apex Class Handler
It is call into cildTriggerhandler.apxt file.
Custom Field:- EmployeeName__c
Custom Child Object with Custom Field
It is custom object with custom field used for display an error if same name being inserted.
