Multiple Unique Keys

Hello everyone. I attempting to construct a table where a single row can be
individually identified by a unique value that is composed of more than one
column. How can define multiple unique keys for a table? Thanks to everyone
for being there to help.Simply include all the appropriate columns in the PK definition:
CREATE TABLE [dbo].[Demo] (
[a] [int] NOT NULL ,
[b] [int] NOT NULL ,
[c] [int] NOT NULL ,
CONSTRAINT [PK_Demo] PRIMARY KEY CLUSTERED
(
[a],
[b],
[c]
)
)
