Which of the following statements is true regarding the ability of queries to write data?

The statement that queries never write data is accurate because in the context of Appian and many other database systems, queries are typically designed for data retrieval rather than modification. Queries utilize Structured Query Language (SQL) commands like SELECT to fetch data without altering the underlying dataset. This is a foundational aspect of how queries function, as their primary role is to provide access to data for reading and analysis.

In contrast, operations that involve writing data—such as INSERT, UPDATE, or DELETE—fall under transactional commands rather than queries. Queries do not possess the capability to alter or write to a database unless explicitly designed to include such commands. Hence, recognizing these distinctions helps in understanding the limitations and roles of queries in both Appian and broader data management systems.
