PDI Question #169: Real Exam Question with Answer & Explanation

Question

A developer is debugging the following code to determinate why Accounts are not being created Account a = new Account(Name = 'A'); Database.insert(a, false); How should the code be altered to help debug the issue?

Options

• AAdd a System.debug() statement before the insert method
• BAdd a try/catch around the insert method
• CSet the second insert method parameter to TRUE
• DCollect the insert method return value a Saveresult variable

Explanation

When using Database.insert() with allOrNone set to false, exceptions are suppressed, and the method returns a SaveResult object that must be inspected to determine success or failure and retrieve error details.

Common mistakes.

• A. Adding a System.debug() before the insert method would only display the record's state prior to the operation, not the actual outcome or any errors that occurred during the insert.
• B. A try/catch block will not catch exceptions when allOrNone is false because Database.insert() suppresses exceptions and returns error information in the SaveResult object instead.
• C. Changing the allOrNone parameter to true would alter the method's behavior to throw an exception on failure, which changes the original debugging scenario where exceptions are suppressed.
