Which of the following items is not a configurable parameter of the a!query() function?

The a!query() function in Appian is used to retrieve data from a data source, and it features a variety of configurable parameters that can influence how data is selected and presented.

Among these parameters, entity, aggregation, filters, and sorting each play a crucial role in defining the structure and content of the query results. However, "entity" refers to the specific data type or table from which data is being pulled, and this is more of a static reference in the context of the function rather than a configurable parameter that modifies how the query behaves.

On the other hand, the aggregation parameter allows for functions like sum or average to be applied to specific fields; filters enable criteria to be set that narrow down the returned results according to certain conditions; and sorting facilitates the ordering of the resulting data set based on specified criteria such as ascending or descending order.

Therefore, while the other items represent aspects of the query that can be customized for various outcomes, the entity serves as a fundamental input that does not alter the functionality of the a!query() method itself, making it distinct in this context.
