Defined List Types
Diese Funktion wird in zukünftigen Versionen von Microsoft SQL Server nicht mehr bereitgestellt. Verwenden Sie diese Funktion beim Entwickeln neuer Anwendungen nicht, und planen Sie das Ändern von Anwendungen, in denen es zurzeit verwendet wird.
Where appropriate, SQL-DMO member functions that return a reference on a SQLObjectList object are implemented to return a reference on a typed list of objects. For example, the ListIndexedColumns member function, that returns an SQLObjectList object enumerating the columns on which a Microsoft® SQL Server™ index is defined, uses the syntax:
HRESULT ListIndexedColumns(LPSQLDMOCOLUMNLIST* ppList);
That the list object returned contains only SQL-DMO Column objects is visible from the function prototype, and for the C/C++ application developer, the typed list forces a specific type recognition and aids in program readability.
SQL-DMO defines the following object list types.
