SYMPTOMS
========

This is a list of nonconformance problems that may occur:

IDBProperties->GetPropertyInfo is not level 0 compliant for certain
properties.

IOpenRowset::OpenRowset gives incorrect results when rgPropertySets = NULL and
cPropertySets <> 0.

IOpenRowset::OpenRowset fails when rgProperties is NULL and cPropertySets
<> 0.

IOpenRowset::OpenRowset returns incorrect error when TableID is NULL.

Opening rowset produces incorrect error when a SETIFCHEAP property set is not
set.

IOpenRowset::OpenRowset fails to return an error when properties are set
incorrectly.

IOpenRowset::OpenRowset does not give correct errors when table ID = NULL.

IDBProperties::GetPropertyInfo causes an exception.

When IDBProperties::GetProperties fails, *prgPropertySets should be NULL but is
not.

IDBProperties tests cause an assertion failure.

QueryInterface for IID_IConnectionPointContainer gives E_NOINTERFACE.

CODBProperty::Save makes unsmurfy call to VariantChangeType--this breaks
IPersistFile::Save.

Attempting to set data to the bookmark column does not result in correct status
value IRowsetNewRow::BMK_key_curs_immed v1.

IRowsetupdate::Insertrow should return DB_E_BADACCESSORHANDLE when accessor = 0
iRowsetNewRow::bound_key_immed v1.

ISessionProperties::GetProperties needs to return null prgPropertySets when error
occurs.

An exception is caused in CODBPropertyManager::GetProperties when it gets invalid
arguments.

Assertion fails in CODBPropertyManager::GetAllProperties -- ulcount = 0.

Another assertion failure--in CODBPropertyManager::GetProperties
rgPropertyIDSets[i].cPropertyIDs = 0.

An exception is caused in CODBPropertyManager::SetProperties when it gets invalid
arguments.

CreateAccessor does not detect binding err conditions well and if it did detect
an error condition, it would not return an error code
IAccessor::TCCreateValidRowAccessors v12.

IConvertType::CanConvert has no validity checking (or use of) dwConvertFlags
icnvttyp::TCcanconvert v5.

Getting DBSCHEMA_INDEXES causes an exception.

GetPropertyInfo does not return correct output values when E_INVALIDARG occurs.

IRowset->TCIRowset_RetrieveData variation 5 causes an exception in
IdataConvert.

CODBIRowsetLocate::GetNextRows does not return correct values when given invalid
arguments IRowset::TCIRowset_Boundary::V7.

CODBIRowsetUpdate::SetData needs to validate arguments before returning with no
error.

When IOpenRowset::OpenRowset fails, ppRowset should be null.

IOpenRowset::OpenRowset returns incorrect error when TableID's pwszName is bad
IOpenrowset::Openrowset v68,69,72, 73.

Opening rowset produces incorrect error when a SETIFCHEAP property is not
succesfully set.

CODBPropertyManager::SetProperties never notices if dwOptions specifies a bad
option.

IOpenRowset::OpenRowset deliberately sets properties even though they are
read-only.

An invalid colid (in the DBPROP structure) is ignored by
CODBPropertyManager::SetProperties.

IOpenRowset::OpenRowset does not check that the interface in riid is supported
when pprowset = NULL.

IOpenrowset::Openrowset v46 fails because we return an invalid hr.

STATUS
======

Microsoft has confirmed this to be a problem in SNA Server 4.0's OLE DB Provider
for AS/400 and VSAM version 1.0.


A supported fix is now available, but has not been fully regression tested and
