Question

How is a view created in SQL?

Answer 1

SQL CREATE VIEW statement is used to create a virtual table that is based on the result set of a SELECT statement. A view does not store any data of its own; instead, it references data from one or more tables in the database. Views are used to simplify complex queries and to provide a consistent interface to the underlying data.

Syntax

CREATE VIEW view_name AS
SELECT column1, column2, ...
FROM table_name
WHERE condition;

In the above syntax, view_name is the name of the view that you want to create. The AS keyword is used to indicate that you are defining a view. The SELECT statement specifies the columns that you want to include in the view. The FROM clause specifies the table(s) from which the view will retrieve data. The WHERE clause is optional and is used to specify a condition that filters the rows returned by the SELECT statement.
