搜索2列并返回转置行中的所有匹配项

Question

我正在尝试使用此QUERY：

=IFERROR(TRANSPOSE(QUERY(Items!$A$2:$D,"SELECT D WHERE A = '"&A2&"' and B = '"&B2&"' and C = '"&C2&"' and C is not NULL and D is not NULL", 0)),)

将其转换为公式，我可以在工作表顶部输入一次，并将其应用于以下列中的所有单元格。

我已经尝试处理在SO上找到/收到的其他各种公式和答案，但是除了错误什么都没有。

=ARRAYFORMULA(IFERROR(VLOOKUP(Estimate!A2:A&Estimate!B2:B, 
 TRIM(IFERROR(SPLIT(TRIM(TRANSPOSE(QUERY(TRANSPOSE(
 {INDEX(QUERY(IFERROR(SPLIT(SORT(UNIQUE(IF((LEN(Items!A2:A&Items!B2:B))*(LEN(Items!C2:C)),
 Items!A2:A&Items!B2:B&"♦"&Items!C2:C, )), 1, 1), "♦")), 
 "select Col1,count(Col1) where Col1 is not null group by Col1 pivot Col2", 0),,1), IF(
 ISNUMBER(QUERY(IFERROR(SPLIT(SORT(UNIQUE(IF((LEN(Items!A2:A&Items!B2:B))*(LEN(Items!C2:C)),
 Items!A2:A&Items!B2:B&"♦"&Items!C2:C, )), 1, 1), "♦")), 
 "select count(Col1) where Col1 is not null group by Col1 pivot Col2", 0)),
 QUERY(IFERROR(SPLIT(SORT(UNIQUE(IF((LEN(Items!A2:A&Items!B2:B))*(LEN(Items!C2:C)), 
 Items!A2:A&Items!B2:B&"♦♥"&Items!C2:C, )), 1, 1), "♦")),
 "select count(Col1) where Col1 is not null group by Col1 pivot Col2 limit 0", 0), )})
 ,,999^99))), "♥"))), {2,3,4,5,6,7,8,9,10,11,12,13,14,15,16}, 0)))

Answer 2

谢谢您提供这么大的公式！想想我正在尝试使用一个简单的FILTER完成此操作。在搜索条件中加入另一列（C列）是否合适？

=ARRAYFORMULA(IFERROR(VLOOKUP('task-itemAssociationsDV'!A2:A&'task-itemAssociationsDV'!B2:B&'task-itemAssociationsDV'!C2:C, 
 TRIM(IFERROR(SPLIT(TRIM(TRANSPOSE(QUERY(TRANSPOSE(
 {INDEX(QUERY(IFERROR(SPLIT(SORT(UNIQUE(IF((LEN(taskData!A2:A&taskData!B2:B&taskData!C2:C))*(LEN(taskData!D2:D)), 
 taskData!A2:A&taskData!B2:B&taskData!C2:C&"♦"&taskData!D2:D, )), 1, 1), "♦")), 
 "select Col1,count(Col1) where Col1 is not null group by Col1 pivot Col2", 0),,1), IF(
 ISNUMBER(QUERY(IFERROR(SPLIT(SORT(UNIQUE(IF((LEN(taskData!A2:A&taskData!B2:B&taskData!C2:C))*(LEN(taskData!D2:D)), 
 taskData!A2:A&taskData!B2:B&taskData!C2:C&"♦"&taskData!D2:D, )), 1, 1), "♦")), 
 "select count(Col1) where Col1 is not null group by Col1 pivot Col2", 0)),
 QUERY(IFERROR(SPLIT(SORT(UNIQUE(IF((LEN(taskData!A2:A&taskData!B2:B&taskData!C2:C))*(LEN(taskData!D2:D)), 
 taskData!A2:A&taskData!B2:B&taskData!C2:C&"♦♥"&taskData!D2:D, )), 1, 1), "♦")),
 "select count(Col1) where Col1 is not null group by Col1 pivot Col2 limit 0", 0), )})
 ,,999^99))), "♥"))), {2,3,4,5,6,7,8,9,10,11,12,13,14,15,16}, 0)))
