SQL Server Views Best Practices

Create a View with Limited Columns

Create a view that selects only the CustomerID and Email columns from the Customers table where customers are active.

Expected output: A view named ActiveCustomerEmails that returns CustomerID and Email for active customers.

Hint: Use a WHERE clause to filter active customers and specify columns explicitly.

Implement Schema Binding on a View

Modify an existing view to include schema binding.

Expected output: A schema-bound view that prevents underlying table changes.

Hint: Add WITH SCHEMABINDING clause and ensure all referenced objects use two-part names.

A view is a virtual table based on a SELECT query. It simplifies complex queries, improves security by restricting data access, and promotes code reuse.

Schema binding locks the view to the underlying table schema, preventing changes to those tables that would break the view.

Indexed views are useful when you have complex aggregations or joins that are frequently queried and need improved performance.
