Introduction to SQL Views

Create a Department Employees View

Create a View that shows employee names and their department names from the Employees and Departments tables.

Expected output: A View that lists employee names alongside their department names.

Hint: Use a JOIN between Employees and Departments tables.

Query a View with Filters

Write a query to select all records from your created View where the department is 'Sales'.

Expected output: All employees who work in the Sales department.

Hint: Use a WHERE clause on the department name.

An SQL View is a virtual table defined by a query. It is used to simplify complex queries, restrict data access, and provide a consistent interface to data without storing it physically.

You can update data through a View only if it is updatable, meaning it meets certain conditions such as referencing a single table and not including aggregations or DISTINCT.

Views can restrict user access to specific columns or rows by exposing only the necessary data, preventing direct access to sensitive underlying tables.
