SOQL Query on child related records

Hello Everyone,

I am new to salesforce development and need help on SOQL query.

We follow account hierarchy (Parent-Child relationship) and all opportunities which we create are associated with child accounts. Need help in querying all the opportunities of the child records which I want to show on parent record.

Regards,
Rahul

HI Rahul ,

In salesforce we have two different types of relationship query .

In salesforce Account is parent and Opportunity is child .  There are two way parent to child and child to parent .

If parent to child then you need to write inner query .
If child to parent then you need to use relationship names in query .

Please check below link it will help .

Let me know incase you have any issue .

Thanks
Manoj

Hi Manoj,

Thanks for the info.

Actually, I want to query related objects of the child object on the parent object.

Here is the scenario:

Parent Account : A
Associated Child Accounts : Child A, Child B
Opportunities are associated with child A and B. 

Now, I want to write a query which provides all the opportunities associated with child accounts (Child A&B) of parent account A.
My actual requirement is to display all the child accounts opportunities, tasks on the parent account related list using VF page.

Regards,
Rahul
