Question

I have a question about views. Consider we have a view that I insert a record in it’s base table. Does my view update after this insert or I should do a SELECT to update?

I think my question obvious – is view just a SELECT or it’s result save in database and if it’s base table, so when it’s updated it then becomes update?

Answer 1

Normal Views are not persisted. If an updateable view is inserted into then selecting from the view (or the affected underlying tables) will show your results.

Not entirely sure what problem you are trying to solve. Views (non-indexed) suffice for most applications.

Have a look at Indexed Views: Improving Performance with SQL Server 2008 Indexed Views:

In the case of a nonindexed view, the portions of the view necessary
to solve the query are materialized at run time. Any computations such
as joins or aggregations are done during query execution for each
query referencing the view. After a unique clustered index is
created on the view, the view’s result set is materialized immediately
and persisted in physical storage in the database, saving the overhead
of performing this costly operation at execution time.

The typical use of an indexed view is when you have expensive aggregations to perform.
