Updating data in a view sql Webcamskorean live
For example, you might define an INSTEAD OF INSERT trigger on a view to replace the standard INSERT statement.Assume you created the below view: ** A view can be used in a query that updates data, subject to a few restrictions.
Provided that you have permissions, you can do the same data manipulation in views that you can do to a table directly.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. Also, executing ALTER TABLE statements on tables that participate in views that have schema binding fail if these statements affect the view definition. VIEW_METADATA Specifies that the instance of SQL Server will return to the DB-Library, ODBC, and OLE DB APIs the metadata information about the view, instead of the base table or tables, when browse-mode metadata is being requested for a query that references the view. When SCHEMABINDING is specified, the base 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 to be modified.
