I recently had to work on a requirement which included nested queries and nested tables. Thanks to the forums and the developer guides, i got the information from a couple of posts and articles.
This article is just a consolidation of information spread over many places.
Scenario:
I will have to display a list of Accounts. Under each account i will have to display the associated Account Team Members.
SOQL Query:
The SOQL Query to retrieve both the Account Details as well as the Account Team Member details will be as follows..
This is what is called a nested query which is quite obvious from the fact that you can see two "Select" statements in a single query..
Now, let us create a simple visualforce page to display the query results.
Visualforce Page:
Controller (Apex Class):
Your final output will look like this.

Visualforce Page:
<apex:page tabstyle="Account" controller="nestedqueryexample">
<apex:pageblock>
<apex:pageblocktable value="{!accsandtmember}" var="accdet">
<apex:column >
<apex:facet name="header">
Team Members
</apex:facet>
<apex:pageblocktable value="{!accdet.AccountTeamMembers}" var="tm">
<apex:column headerValue="Team Member">
<apex:outputfield value="{!tm.User.Name}"/>
</apex:column>
<apex:column headerValue="Role">
<apex:outputfield value="{!tm.TeamMemberRole}"/>
</apex:column>
</apex:pageblocktable>
</apex:column>
<apex:column headervalue="Account Name">
<apex:outputtext value="{!accdet.Name}"/>
</apex:column>
<apex:column headervalue="Billing Country">
<apex:outputtext value="{!accdet.BillingCountry}"/>
</apex:column>
</apex:pageblocktable>
</apex:pageblock>
</apex:page> Controller (Apex Class):
public class nestedqueryexample
{
public List<Account> getaccsandtmember()
{
List<Account> accounts = [Select Id,(Select TeamMemberRole, User.Name From Account.AccountTeamMembers), Name, BillingCountry from Account];
return accounts;
}
}
Your final output will look like this.
Looks messy rite?. We will add a expand/collapse button for the nested table to make it look clean.
