Use following reference

There are two types of SOQL queries that we can use :

 

1.      Child to parent

2.      Parent to child

 

If you want to get data from child object, then can use parent to child query. For an example Account and contact have parent- child relationship. For accessing data from contact query would be like :

 

List<Account> acc=[select id,Name,(select id,lastName,firstname from Contact) from Account limit 100];

 

This query returns 100 accounts and all contacts related to each account.
