What are view tables in SQL?

Question

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.

What is the use of view tables?

Views can join and simplify multiple tables into a single virtual table. Views can act as aggregated tables, where the database engine aggregates data (sum, average, etc.) and presents the calculated results as part of the data. Views can hide the complexity of data.

What is a view vs a table?

A table is structured with columns and rows, while a view is a virtual table extracted from a database. The table is an independent data object while views are usually depending on the table.

What is a view and table in DB?

Definition. A view is a database object that allows generating a logical subset of data from one or more tables, while a table is a database object or an entity that stores the data of a database.

Why use views instead of tables SQL?

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.
