What do we call an SQL virtual table constructed from one or more base tables using a saved SELECT definition?

Introduction / Context:
Views are a core abstraction in SQL that present data from base tables through a stored query, often to simplify access or enforce security.

Given Data / Assumptions:

• A virtual table is mentioned.
• The definition is created from other tables via a SELECT.

Concept / Approach:
A view is defined with CREATE VIEW ... AS SELECT ... and behaves like a table in queries, though it does not store its own data (except materialized variants). It is distinct from ad hoc query results, which are transient.

Step-by-Step Solution:

Verification / Alternative check:
Attempt SELECT * FROM view_name after creation; this works like selecting from a table.

Why Other Options Are Wrong:

• “Just another table”: physical tables store rows; a view is virtual.
• “A relation”: generic term for a table, not specific to virtual constructs.
• “Query results”: ephemeral; a view is persistent metadata.

Common Pitfalls:
Assuming views permanently store data; unless materialized, they compute results at query time.

Final Answer:
A view
