This question runs in a pre-configured Salesforce environment - no personal connection required.

Create a method that updates an Account's AnnualRevenue using DML operations.

Parameters:

  • accountId (Id): The ID of the account to update
  • newRevenue (Decimal): The new annual revenue value

Returns:

  • Boolean: true if update successful, false otherwise

Requirements:

  • Use DML update operation
  • Handle null accountId by returning false
  • Query the account first to ensure it exists
  • Handle DML exceptions gracefully

Example:

Boolean success = updateAccountRevenue(accountId, 1000000);
// Returns: true if successful
