What is the difference between SQL table and SQL view?
The primary distinction is that a table is an object made up of rows and columns. And it is mainly used to store and retrieve data whenever the user requires it. The view, on the other hand, is a virtual table based on the result set of a SQL statement that will be lost when the current session ends.
What is a view of a table?
A view is actually a composition of a table in the form of a predefined SQL query. A view can contain all rows of a table or select rows from a table. A view can be created from one or many tables which depends on the written SQL query to create a view.
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.
Why do we use view 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.
