データベース内のすべてのテーブルで、PK (複合または非複合) の一部であるすべての列を特定したいと考えています。SQLステートメントでそれを行うにはどうすればよいですか? 望ましい結果セット:

テーブル名 | 列名 | データ型 | 制約 |

これはずっと前に自分のスニペット フォルダにコピーしたものなので、信用はできませんが、これはうまく機能します...

select s.name as TABLE_SCHEMA, t.name as TABLE_NAME, k.name as CONSTRAINT_NAME, c.name as COLUMN_NAME, ic.key_ordinal AS ORDINAL_POSITION
  from sys.key_constraints as k
  join sys.tables as t
    on t.object_id = k.parent_object_id
  join sys.schemas as s
    on s.schema_id = t.schema_id
  join sys.index_columns as ic
    on ic.object_id = t.object_id
   and ic.index_id = k.unique_index_id
  join sys.columns as c
    on c.object_id = t.object_id
   and c.column_id = ic.column_id
 where k.type = 'PK';
