EnumCandidateKeys Method
This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
The EnumCandidateKeys method returns a QueryResults object that enumerates the user tables of a Microsoft SQL Server database and the constraints on those tables that could define primary keys.
