What is Views?
VIEW:
A view is nothing more than a SQL statement that is stored in the
database with an associated name. A view is actually a composition of a
table in the form of a predefined SQL query. A view can contain all rows of a table or select rows from a table. A
view can be created from one or many tables which depends on the
written SQL query to create a view.
Views, which are kind of virtual tables, allow users to do the following:- Structure data in a way that users or classes of users find natural or intuitive.
- Restrict access to the data such that a user can see and (sometimes) modify exactly what they need and no more.
- Summarize data from various tables which can be used to generate reports.
Creating Views:
Database views are created using the CREATE VIEW statement. Views can be created from a single table, multiple tables, or another view.To create a view, a user must have the appropriate system privilege according to the specific implementation.
The basic CREATE VIEW syntax is as follows:
CREATE VIEW view_name AS SELECT column1, column2..... FROM table_name WHERE [condition];
