Which query type would you use to modify existing records in a database?

• A. Select query
• B. Action query
• C. Data query
• D. Report query

Answer: (B)

The appropriate query type to use for modifying existing records in a database is an action query. Action queries are specifically designed for operations that perform actions on the data, such as updating, inserting, or deleting records. When you execute an action query, you can change the data in the table based on specified criteria, which is essential for maintaining or correcting information within the database. In contrast, a select query is intended for retrieving data from the database without making any changes. It simply fetches records based on defined conditions but does not alter them. Data queries, while related, do not specifically refer to a recognized category of queries in most database systems. Similarly, report queries are designed to format and present data, typically for viewing or printing, rather than for making modifications. Therefore, the action query is the correct choice for modifying records, as it encapsulates the necessary functionality for performing updates and other changes to the data.
