Enhanced Apex Functionality: Dive Deeper with Five-Level Parent-to-Child Relationship SOQL Queries

• Now, in the latest version of Apex, you can dig deeper into your data than ever before. Imagine you have different types of records connected to each other, like a family tree. Previously, you could only look at a certain number of "branches" in that tree at once, but now you can go five levels deep. This means you can explore relationships between different types of data in more detail.
• So, let's say you're looking at a record, like a person in a family tree, you can now easily see their parents, grandparents, great-grandparents, and even further up the family tree. This gives you a much better understanding of how different pieces of information are connected.
• And to ensure everything runs smoothly, In API version 61.0 and later, Apex keeps track of how much of this detailed exploration you're doing. So, you can confidently dive into your data without worrying about overwhelming the system.

This example SOQL query statement includes five levels of parent-child relationships.

List<Account> accts = 
[SELECT Name,
    (SELECT LastName,
        (SELECT AssetLevel,
            (SELECT Description,
                (SELECT LineItemNumber FROM WorkOrderLineItems)    
            FROM WorkOrders)    
        FROM Assets)    
    FROM Contacts)    
FROM Account];
