Question

Hypothetically I have two tables Employee and Locations. Additionaly I have a view viewEmpLocation which is made by joining Employee and Locations.

If I update the view, will the data in the original table get updated?

Answer 1

see Using Views in Microsoft SQL Server

When modifying data through a view
(that is, using INSERT or UPDATE
statements) certain limitations exist
depending upon the type of view. Views
that access multiple tables can only
modify one of the tables in the view.
Views that use functions, specify
DISTINCT, or utilize the GROUP BY
clause may not be updated.
Additionally, inserting data is
prohibited for the following types of
views:

* views having columns with derived (i.e., computed) data in the SELECT-list  
* views that do not contain all columns defined as NOT NULL from the tables from which they were defined

It is also possible to insert or
update data through a view such that
the data is no longer accessible via
that view, unless the WITH CHECK
OPTION has been specified.
