What is a view? is View updatable?..

Answer / rhys

A view is a "virtual" (isn't physically stored) table. It hides complex details (you can join multiple tables together), provides security/privacy (users can set which columns are available for different people) and it allows read-only access.

The view data dictionary will be updated along side the master data dictionary. For example, if I updated a client's name in the master table, the view would also be amended.

What is a view? is View updatable?..

Answer / waseem

a view is a virtual table based on the result-set of an SQL
statement.
The fields in a view are fields from one or more real tables
in the database.

You can add SQL functions, WHERE, and JOIN statements to a
view and present the data as if the data were coming from
one single table.
A view always shows up-to-date data! The database engine
recreates the data, using the view's SQL statement, every
time a user queries a view.

What is a view? is View updatable?..

Answer / gunjan sapra

View is a virtual table,created by users for their own
convienience.
views can be updated as required but the updated data will
not reflect in the base table, since view is the virtual
table not the original table.
so, if we want to update the table we have to update that
outside the view or directly but not using view.
if we update through view its temporary means just in the
view only but will not reflect in the base table.
