Creating VIEW Table
The syntax of the view table is the same as the creation of any other table in SQL. Still, as it is a result of another query, an original table must exist from where the data or records can be inserted into the view table. Let’s see how the view table is created,
Syntax:
CREATE VIEW view_name AS
SELECT column_1,column_2,…..
FROM table_name;
The view can be created from any number of columns in a table and can be used along with the where condition.
Which is Faster Simple Query or VIEW in SQL?
In SQL, a view is a virtual table that can be created and accessed when required similar to the tables in a database. A virtual table or view is a saved query that can be frequently accessed and does not require any storage in a database. It is created and used to reduce the complexity of subqueries.
Consider a situation where you want to retrieve the records in a table related to your work from a huge data, and you can’t perform operations or manipulate the original table data. Virtual tables (VIEWS) are used. You can filter out the records from the table using SQL queries and work on the view table. This way, the data integrity is maintained and you can easily query the view table.
