Example text

Things are fuzzy here because the TOP option is not standard. But if you try to think in terms of sets, the ORDER BY clause is meaningless because you’re selecting all rows that meet the filter expression. Chapter 1 Views 5 When querying the view, SQL Server does not have to guarantee any order of the output unless the outer query has an ORDER BY clause. SQL Server 2008 Books Online has a helpful statement describing this behavior: “The ORDER BY clause is used only to determine the rows that are returned by the TOP clause in the view definition.

The view’s cname value for order 1001 was the cname value from the Customers table associated with o ­ rder 1001’s customer (customer number 1, as stored in the Orders table). The view returned ­customer number 1’s cname value for all three of customer number 1’s orders. Customers; View Options When you create or alter a view, you can specify options that will control the view’s behavior and functionality. The options ENCRYPTION, SCHEMABINDING, and VIEW_METADATA are specified in the view’s header, and the CHECK OPTION is specified after the query.

Customers DROP COLUMN address; You get the following error: Msg 5074, Level 16, State 1, Line 1 The object 'CustsWithOrders' is dependent on column 'address'. Msg 4922, Level 16, State 9, Line 1 ALTER TABLE DROP COLUMN address failed because one or more objects access this column. The error indicates which objects depend on the column that you’re trying to drop. Using SQL Server 2008, you can query new dynamic management objects that provide reliable ­dependency information to identify object dependency before you attempt a schema change.
