? CREATE VIEW in SQL

A View is a virtual table based on the result set of a SQL query. It does not store data physically, but you can query it like a regular table.

? Syntax

CREATE VIEW view_name ASSELECT column1, column2, ...FROM table_nameWHERE condition;

? Example

Create a view that shows employees in the Sales department:

CREATE VIEW sales_employees ASSELECT id, first_name, last_name, emailFROM employeesWHERE department = 'Sales';

? Using the View

After creating the view, you can query it like a table:

SELECT * FROM sales_employees;

? Notes

• Views simplify complex queries.

• They help with security by restricting access to certain columns or rows.

• Views reflect changes in the underlying tables dynamically.

• Some databases support updatable views (you can insert/update through the view), others do not.

If you want, I can show examples of updatable views, dropping views, or views with joins!
