Defined List Types
この機能は、将来のバージョンの Microsoft SQL Server では削除される予定です。 新しい開発作業では、この機能の使用を避け、現在この機能を使用しているアプリケーションは修正するようにしてください。
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.
