sql-server - partitioned - view with encryption sql server




Why do SQL Server Views needs to be refreshed every once in a while (2)

Why do I have to write 'refresh view' scripts, and execute them every time I add or edit some fields to a view?

SQL Server understands that it needs to refresh the view when editing it in the fancy view-edit windows in Management Studio, so why can't it just tell its view to go refresh itself after editing the view through a script?


Use WITH SCHEMABINDING in the view definition to remove the need for any refreshes

And in combination with ALTER VIEW, not the designer

Edit, Jul 2012, from link above. My bold

SCHEMABINDING

Binds the view to the schema of the underlying table or tables. When SCHEMABINDING is specified, the base table or tables cannot be modified in a way that would affect the view definition. The view definition itself must first be modified or dropped to remove dependencies on the table that is to be modified. When you use SCHEMABINDING, the select_statement must include the two-part names (schema.object) of tables, views, or user-defined functions that are referenced. All referenced objects must be in the same database.

Views or tables that participate in a view created with the SCHEMABINDING clause cannot be dropped unless that view is dropped or changed so that it no longer has schema binding. Otherwise, the Database Engine raises an error. Also, executing ALTER TABLE statements on tables that participate in views that have schema binding fail when these statements affect the view definition.


Views need to be refreshed if the underlying tables change at all. That can change the datatypes of the view's columns or rearrange its indexes. Therefore, it needs to know. Otherwise, you'd run a query against it, and it'd blow up pretty quickly.

You shouldn't have to run sp_refreshview for altering a view. Only for altering its underlying tables.

Also, please do not taunt happy fun ball.

Edit: Just ran this code (in succession) to attempt to reproduce your problem. I was, unfortunately, unable to, as it worked as expected (SQL Server 2008):

create view MyView
as
select ProductKey, ProductID, ProductName, Price
from dbo.Products

select v.* from MyView v

alter view MyView
as
select ProductKey, ProductID, ProductName, Price*100 as MyPrice
from dbo. Products

select v.* from MyView v
