麻煩建立一個SQL連接

Question

我想檢查表「T2」的3個字段的值一起出現在表「T1」每個用戶的東西加入這樣的：

] 1

預期的結果：

這是可能的呢？如果是的話，你可以幫忙建立一個查詢嗎？

謝謝

假設基礎上發佈的例子：只有3個因素和因素在T1的任何領域。

需要在每個表中的唯一標識符字段，自動編號應該服務。

查詢：T1_UNION（A UNION查詢必須輸入（或在查詢生成器的SQLView複製/粘貼）。）
SELECT RecID_T1, "R1" AS Cat, R1 AS Data FROM T1 UNION SELECT RecID_T1, "R2", R2 FROM T1 UNION SELECT RecID_T1, "R3", R3 FROM T1;

查詢：T2_CROSSTAB
TRANSFORM First(T2.R) AS FirstOfR SELECT T2.U FROM T2 GROUP BY T2.U PIVOT DCount("*","T2","U='" & [U] & "' AND RecID_T2<" & [RecID_T2])+1;

查詢：
SELECT T2_CROSSTAB.U, DLookUp("Data","T1_UNION","Data='" & [1] & "'") AS IsMatch1, DLookUp("Data","T1_UNION","Data='" & [2] & "'") AS IsMatch2, DLookUp("Data","T1_UNION","Data='" & [3] & "'") AS IsMatch3 FROM T2_CROSSTAB WHERE ((Not (DLookUp("Data","T1_UNION","Data='" & [1] & "'")) Is Null) AND (Not (DLookUp("Data","T1_UNION","Data='" & [2] & "'")) Is Null) AND (Not (DLookUp("Data","T1_UNION","Data='" & [3] & "'")) Is Null));

使用Joe C的想法，CROSSTAB是不需要的。

查詢：Data_GROUPED
SELECT T2.U, T2.R FROM T2 INNER JOIN T1_UNION ON T2.R = T1_UNION.Data GROUP BY T2.U, T2.R ORDER BY T2.U;

查詢：
SELECT Data_GROUPED.U, Count(Data_GROUPED.R) AS CountOfR FROM Data_GROUPED GROUP BY Data_GROUPED.U HAVING (((Count(Data_GROUPED.R))=3));
