Defined List Types (SQL-DMO)

Where appropriate, SQL-DMO member functions returning a reference on a SQLObjectList object are implemented to return a reference on a typed list of objects. For example, the ListIndexedColumns member function, returning a 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.
