SALESFORCE-PD1 Developer Fundamentals Practice Question
An Apex trigger needs to query related Account records for a list of newly inserted Contact records. What is the most robust way to handle the relationship query in SOQL to avoid governor limits?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Collect Account IDs into a Set and execute a single SOQL query outside the loop using the IN clause.
Using a parent-to-child or child-to-parent relationship query inside a single SOQL statement executed on the Trigger.new collection prevents hitting the SOQL query governor limit.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Access standard relationship fields directly without querying if the records are in Trigger.new.
Why it's wrong here
Trigger.new only contains fields for the object itself, not parent fields unless queried.
- ✗
Loop through each Contact and issue a separate SOQL query for its Account.
Why it's wrong here
This violates governor limits by issuing SOQL queries inside a loop.
- ✗
Use the Database.getQueryLocator method with Trigger.new.
Why it's wrong here
getQueryLocator is used primarily for batch apex, not standard trigger context.
- ✓
Collect Account IDs into a Set and execute a single SOQL query outside the loop using the IN clause.
Why this is correct
This is a best practice for bulkification, avoiding queries inside loops.
