Composite or Primary Key

How do determine within SQL Server if key is a Primary Key
or Composite Key (Take two or more fields to uniquely
adentify a record.)? List Primary Key properties?
Thank You,
JimHi,
If a primary key is constructed with more than 1 columns then it is named as
Composite primary key.
Use the system stored procedure to identify the primary key.
sp_primary_keys_rowset @.table_name
If we have multiple entries with Ordinal (1,2,3..) then it is Composite key.
Note: you can even use sp_help <table name> to get the key information.
Thanks
