how create query gives me list of tables composite primary key in sql server? maybe using sys.tables or information_schema.tables or else?

select col.table_name  information_schema.table_constraints tc  join information_schema.constraint_column_usage col   on col.constraint_name = tc.constraint_name  , col.table_name = tc.table_name  , tc.constraint_type = 'primary key ' group col.table_name having count(*) > 1
