Hi @shyam sundar 112

Let's assume, You have a child object is "Account". parent one is the "Country" object.

There is one name field in "Country".

1) Name of Country

One Country record is - India

There is a picklist in the account object is the "Selected country".

EX value is - 'India'.

The trigger in Account is ->


Trigger accountTrigger on Account (before Insert) {
    Set<Id> SelectedCountryId = new Set<Id>();
    for (Account acc : Trigger.New) {
    Map<Id, Country__c> countries = new Map<Id, Country__c>([SELECT Id, Name FROM countries WHERE Id IN: SelectedCountryId]);
    for (Account acc : Trigger.New) {
        //countryName__c  is the picklist field name
        acc.countryName__c = countries.get(acc.Country__c).Name;
