Interface Methods

GetProperties	Returns the values of properties in the Data Source, Data Source Information, and Initialization property groups that are currently set on the data source object or the values of properties in the Initialization property group that are currently set on the enumerator.
GetPropertyInfo	Returns information about all properties supported by the provider.
SetProperties	Sets properties in the Data Source and Initialization property groups, for data source objects, or the Initialization property group, for enumerators.

Remarks

IDBProperties is a mandatory interface for data source objects and an optional interface for enumerators. However, if an enumerator exposes IDBInitialize, it must expose IDBProperties. IDBPropertiesImpl implements IDBProperties by using a static function defined by BEGIN_PROPSET_MAP.

Requirements

Header: atldb.h
