ICommand::GetDBSession

Returns an interface pointer to the session that created the command.

HRESULT GetDBSession (
   REFIID         riid,
   IUnknown **   ppSession);

Parameters

riid

[in]
The IID of the interface on which to return a pointer.

ppSession

[out]
A pointer to memory in which to return the interface pointer. If the provider does not have an object that created the command, it sets *ppSession to a null pointer. If GetDBSession fails, it must attempt to set *ppSession to a null pointer.

Return Code

S_OK
The method succeeded.

S_FALSE
The provider did not have an object that created the command. Therefore, it set *ppSession to a null pointer.

E_FAIL
A provider-specific error occurred.

E_INVALIDARG
ppSession was a null pointer.

E_NOINTERFACE
The session did not support the interface specified in riid.
