1. Syntax of Creating a View
CREATE VIEW view_name AS
SELECT column_name(s)
FROM table_name
WHERE condition;
view_name: Name of the view.SELECT statement: Defines the data to be retrieved.Let’s assume we have a table employees with columns id, name, department, and salary. We want to create a view that only displays employees from the "IT" department.
CREATE VIEW IT_Employees AS
SELECT id, name, salary
FROM employees
WHERE department = 'IT';
In this example:
IT_Employees view filters only employees from the IT department.SELECT * FROM IT_Employees;
MySQL Views provide an efficient way to simplify database management by allowing users to create reusable virtual tables. They enhance security, simplify queries, and improve database efficiency.
