An SQL ____ is a virtual table, whose contents are based on the SQL statement's results.*ConcatenateVirtualViewNone of the above

The correct answer is View.

Explanation

An SQL view is essentially a virtual table that does not store data itself but derives its contents from a query that selects data from one or more underlying tables. When you query a view, you are executing the SQL statement that defines the view, effectively providing a dynamic window into a specific set of data.

In the context of the provided options:

1. Concatenate - This term relates to combining strings or data but does not refer to a virtual table.
2. Virtual - While this could imply the concept of a virtual table, it specifically does not define the SQL object.
3. View - Correct term for a virtual table in SQL, representing the results of a query.
4. None of the above - Incorrect since "View" is the right answer.

Therefore, the answer is "View."
