Sql view not updating
For example, you could create a view for a salesperson that only displays her own orders, or you might create a view for the manager, who is only interested in seeing the total sales for each salesperson. Figure 9.1 shows the Permissions dialog box for vw Customeraddress List.Views give you a mechanism for presenting the same data to different users in different ways. As long as both the view and the Customers table are owned by dbo, the permissions granted on the view will take precedence over permissions removed from the Customers table. Because views allow you to restrict the rows and columns that are available, using them as a security tool is very convenient.So, a view that returns the top 100% by sales would essentially be a sorted view.The triggers in views are covered later in this chapter.Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.Visit Stack Exchange Database Administrators Stack Exchange is a question and answer site for database professionals who wish to improve their database skills and learn from others in the community.

Im working with Sql Server 2008 R2 thanxs If you use two-part-naming and your script has to be run on multiple databases you will run into a problem when there are different Schemas across databases.
Did you know that you can easily generate the list of columns from Object Explorer by right-clicking and saying Script View/Table As is okay.In that scenario you have to use dynamic SQL to create the scripts.Visit Stack Exchange Database Administrators Stack Exchange is a question and answer site for database professionals who wish to improve their database skills and learn from others in the community. Sign up to join this community I am creating a number of proxy views for views in a separate database.A view can be used to wrap up complex queries containing subqueries, outer joins, and aggregation. Another problem you'll encounter with Access projects (ADPs) is that if you want users to be able to update data using a view, you also have to grant them permissions on the underlying tables.
This simplifies access to the data because the underlying query does not have to be written on the client and then submitted each time a report is run. Although you can set column-level security in SQL Server, it is tricky to maintain because it's pretty well buried in the table properties.
Columns and rows can be restricted, allowing users to focus on specific data that interests them. This also helps network performance because less data is traveling over the wire to client applications. For example, you could create two views on an Employees table, one with a sensitive salary column included that only managers had permissions on, and a second view with that column omitted for everyone else.
