You can restrict a view to only n rows or m percent of the rows in an underlying base table by specifying a TOP n or TOP m PERCENT clause, respectively, in the view definition. This option provides a fast method to obtain a restricted, statistically non-random sample of table rows without scanning the entire table. For example, you might create a view that specifies only the top 10 rows, or only the top 10 percent of the rows, from an orders table.
