Is a view a table?
In SQL, a view is a virtual table based on the result-set of an SQL statement. A view contains rows and columns, just like a real table. The fields in a view are fields from one or more real tables in the database.
Why do we use views instead of tables?
Views can provide advantages over tables: Views can represent a subset of the data contained in a table. Consequently, a view can limit the degree of exposure of the underlying tables to the outer world: a given user may have permission to query the view, while denied access to the rest of the base table.
What is the difference between Oracle table and view?
Unlike a table, a view does not store any data. To be precise, a view only behaves like a table. And it is just a named query stored in the database. When you query data from a view, Oracle uses this stored query to retrieve the data from the underlying tables.
Is view better than table?
A Table is defined as a database object which is used to store data in a database. Tables stores data in a logically organized row-column format. A View is just like a virtual table that holds data from one or more than one table. A view includes a set of SQL queries for retrieving data from the database.
