Updates the metadata for the specified non-schema-bound view. Persistent metadata for a view can become outdated because of changes to the underlying objects upon which the view depends.

Syntax

sp_refreshview [ @viewname = ] 'viewname'

Arguments

[ @viewname= ] 'viewname'
Is the name of the view. viewname is nvarchar, with no default. viewname can be a multipart identifier, but can only refer to views in the current database.

Return Code Values

0 (success) or a nonzero number (failure)

Remarks

If a view is not created with schemabinding, sp_refreshview should be run when changes are made to the objects underlying the view that affect the definition of the view. Otherwise, the view might produce unexpected results when it is queried.

Permissions

Requires ALTER permission on the view and REFERENCES permission on common language runtime (CLR) user-defined types and XML schema collections that are referenced by the view columns.

Examples

A. Updating the metadata of a view

The following example refreshes the metadata for the view Sales.vIndividualCustomer.

USE AdventureWorks2012;
GO
EXECUTE sp_refreshview N'Sales.vIndividualCustomer';

B. Creating a script that updates all views that have dependencies on a changed object

Assume that the table Person.Person was changed in a way that would affect the definition of any views that are created on it. The following example creates a script that refreshes the metadata for all views that have a dependency on table Person.Person.

USE AdventureWorks2012;
GO
SELECT DISTINCT 'EXEC sp_refreshview ''' + name + '''' 
FROM sys.objects AS so 
INNER JOIN sys.sql_expression_dependencies AS sed 
    ON so.object_id = sed.referencing_id 
WHERE so.type = 'V' AND sed.referenced_id = OBJECT_ID('Person.Person');
