Null Coalescing Operator (Spring 24 Apex)

The ?? Operator returns the left-hand argument if the left-hand argument isn't null. Otherwise, it returns the right-hand argument.

 

// Left operand SOQL is empty, return defaultAccount from right operand:

Ex :

Account defaultAccount = new Account(name = 'Acme');

Account a = [SELECT Id FROM Account WHERE Id = '001000000FAKEID'] ?? defaultAccount;

Assert.areEqual(defaultAccount, a);
