Shweta Soparkar Trigger for updating the details object in a master details relationship
I have a master detail relationship wherein I have a master custom object named Contact and a detail relationship object Associated Account.
Now , in associated Account there is a field named primary account. One contact can be associated with many accounts but a contact can have only one primary account. So, here I want to write a trigger where whenever a user tries to create a record in associated account the trigger should fire and set all the primary account except the latest one to false(primary account is a checkbox). and the same should be reflected in contact.

Set<Id> contactIds = new Set<Id>();
for(Associated_Account__c d : trigger.new){
if(d.Primary_Account__c== true)
{
contactIds.add(d.Contact__c);
associatedAccountIds.add(d.id);
}
}
vwo = [SELECT id,Primary_Account__c FROM Associated_Account__c
WHERE Primary_Account__c=true AND Contact__c IN :contactIds AND Id NOT IN :associatedAccountIds];
for(Associated_Account__c d:vwo)
d.Primary_Account__c=false;
update vwo;
// Updating the Master Record- Contact Object
List<Id> accName= new List<Id>();
List<Associated_Account__c> aa= new List<Associated_Account__c>();
aa =[select id, Associated_Account__c from Associated_Account__c WHERE Primary_Account__c=true AND Contact__c IN :contactIds];
for(Associated_Account__c d: aa)
accName.add(d.Associated_Account__c);
List<Contact> con= new List<Contact>();
con= [select AccountId from Contact where Id IN :contactIds];
for(Contact c : con)
c.AccountId= accName.get(0);
update con;
