CREATE VIEW command creates a virtual table based on a saved query. The resulting view can be accessed via a
SELECT statement, just like a normal table in the database.
CREATE VIEW viewname AS
viewname is a valid SQL name and
SELECT statements can be any valid
SELECT query involving any number of tables and may include
HAVING, or any type of
JOIN. A view can also reference other views as well as tables.
Note: A view will require each column to have a unique name.
The following example creates a view named
student_count_by_country based on a
SELECT statement grouping the
students table by
CREATE VIEW student_count_by_countryASSELECT COUNT(student_name) AS student_count,birth_countryFROM studentsGROUP BY birth_country
