2 つのテーブルを結合し、次のように出力を取得する必要があります

T1

S    B   C   P
---  --  --  --
ABC  B1  C1  10
ABC  B2  C2  11
ABC  B3  C3  12

T2

S    B   C   P
---  --  --  --
ABC  B1  C1  12
ABC  B2  C2  13
ABC  B5  C5  14

以下の出力が必要です

S    B   C   P1  P2
---  --  --  --  --
ABC  B1  C1  10  12
ABC  B2  C2  11  13
ABC  B3  C3  12  0
ABC  B5  C5  0   14

注: Microsoft Access を使用していますが、Access SQL は FULL OUTER JOIN クエリを直接サポートしていません。
