What is a recommended approach when checking for the existence of an entity?

The recommended approach of verifying that the results of a targeted query are not empty is a practical and efficient strategy in checking for the existence of an entity. This method ensures that you specifically search for the entity you are interested in, using a focused query that targets the exact parameters relevant to that entity.

By executing a query and checking if the results return values, you can directly assess whether the entity exists in the dataset. This approach minimizes the resources used compared to counting all entities or filtering with select().Count, as those methods may involve unnecessary processing overhead.

Thus, querying and checking for an empty result is both efficient and straightforward, making it the best practice when you need to determine the existence of a specific entity in Guidewire.
