SQL Views
Views in SQL are a type of virtual table that simplifies how users interact with data across one or more tables. Unlike traditional tables, a view in SQL does not store data on disk; instead, it dynamically retrieves data based on a pre-defined query each time it’s accessed.
SQL views are particularly useful for managing complex queries, enhancing security, and presenting data in a simplified format. In this guide, we will cover the SQL create view statement, updating and deleting views, and using the WITH CHECK OPTION clause.
What is a View in SQL?
A view in SQL is a saved SQL query that acts as a virtual table.
It can fetch data from one or more tables and present it in a customized format, allowing developers to:
- Simplify Complex Queries: Encapsulate complex joins and conditions into a single object.
- Enhance Security: Restrict access to specific columns or rows.
- Present Data Flexibly: Provide tailored data views for different users.
We will be using these two SQL tables for examples.
