Management asked for opportunities to be automatically created for accounts with annual revenue greater than $1, 000,000. A developer created the following trigger on the Account object to satisfy this requirement.

for (Account a : Trigger.new) {

if (a.AnnualRevenue > 1000000) {

List oppList = [SELECT Id FROM Opportunity WHERE AccountId = :a.Id];

if (oppList.size() == 0) {

Opportunity oppty = new Opportunity(Name = a.Name, StageName = 'Prospecting', CloseDate = System.today().addDays(30));

insert oppty;

}

}

}

Users are able to update the account records via the UI and can see an opportunity created for high annual revenue accounts. However, when the administrator tries to upload a list of 179 accounts using Data Loader, it fails with system, Exception errors.

Which two actions should the developer take to fix the code segment shown above?
