SQL Server Interview Topic 34: Views and Report Security
This topic checks whether you can use views to simplify reports and protect data exposure.
You should be able to explain what a view is, when it helps, and how it can support secure reporting.
Q205. What is a view in SQL Server?
Quick interview answer:
A view is a saved SELECT query that can be used like a table. It does not normally store data by itself. It helps simplify repeated joins or report queries.

Q206. Why do developers use views?
Quick interview answer:
Developers use views to reuse common query logic, simplify complex joins, and make reports easier to read. For example, a view can show active students with class details.

Q207. Can views improve security?
Quick interview answer:
Yes. A view can expose only selected columns and hide sensitive columns from users or reports. Permissions can be given on the view instead of the base table in some designs.

Q208. Can a view replace all stored procedures?
Quick interview answer:
No. A view is mainly for reusable SELECT logic. Stored procedures can accept parameters and run multiple statements. Use each one for the right purpose.

Q209. What should you avoid in report views?
Quick interview answer:
Avoid making a view too large, too slow, or unclear. A view should not hide bad query design. If the report is heavy, check indexes, filters, and execution plan.

Say views are useful for reusable read logic, not as a magic performance fix.
