Key columns in SQL Server Everywhere Edition

I have noticed that Microsoft SQL Server 2005 Everywhere Edition OLE DB Provider doesn't support DBPROP_UNIQUEROWS property from
DBPROPSET_ROWSET property set. Does it mean that I have to use the KEY_COLUMN_USAGE rowset to get list of key columns in table?

Moving to the "Transact-SQL" forum.|||Thank you for your help
