What is the function used primarily for querying records in Appian?

The function used primarily for querying records in Appian is a!queryRecordType. This function is designed specifically to retrieve data from a specified record type, which represents a collection of related data entities stored in Appian's data management system. By utilizing this function, developers can access and manipulate records efficiently while applying various filters, sorts, and pagination options to return precisely the data required for their applications.

In the context of Appian, records serve as a foundational element, allowing for a structured view of business data that can be easily queried and displayed. The a!queryRecordType function effectively pulls data from these structured records, facilitating the development of dynamic and data-driven applications.

Other options refer to different functionalities within Appian: a!startProcess is used to initiate a process model, a!recordType defines the structure and attributes of a specific record type rather than querying it, and a!initializeVariables is utilized to declare and configure variables, but it does not handle data queries. Hence, a!queryRecordType is clearly the choice that aligns directly with querying records.
