Defined List Types

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.

Type	SQLObjectList object contains
LPSQLDMODBOBJECTLIST	DBObject objects
LPSQLDMOPERMISSIONLIST	Permission objects
LPSQLDMOCONFIGVALUELIST	ConfigValue objects
LPSQLDMOBACKUPDEVICELIST	BackupDevice objects
LPSQLDMOCOLUMNLIST	Column objects
LPSQLDMOUSERDEFINEDDATATYPELIST	UserDefinedDatatype objects
LPSQLDMOSTOREDPROCEDURELIST	StoredProcedure objects
LPSQLDMOLOGINLIST	Login objects
LPSQLDMOUSERLIST	User objects
LPSQLDMODATABASELIST	Database objects
LPSQLDMOKEYLIST	Key objects
