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 AdventureWorks2008R2;
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 AdventureWorks2008R2;
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');
