に応じて列内のグループフィールドに、クエリでどのように：私はTOS値のグループ、特定の値に必要

RSA_CASTLEMEAD_1941$.TOS 
FULL OUTER JOIN RSA_CHELMSFORD_1941$  ON REF.TOS = 
RSA_CHELMSFORD_1941$.TOS 

と出力されますTOS値列に直接関係する他の列には影響を与えずに、「親」グループの下にある列を選択します。

は私が達成するために必要なものの考え方については、以下の画像を参照してください。

あなたが長いったらしい自己結合を行うことができますが、これはSQL Serverですので、我々は、ピボットテーブルを活用することができますクエリ。
