問題描述
如何在 Google 表格中使用 ArrayFormula 計算總數和唯一性（基於 2 個單獨的列）？ (How to count totals and uniques (based on 2 separate columns) using ArrayFormula in Google Sheets?)
我有以下電子表格：
https://docs.google.com/spreadsheets/d/1pBL21fyuxYNb5YfERsFl7Y‑CTdQEH7SgJQfuOdQ0V6c/edit?usp=sharing
前 2 列計算操作總數並對其進行排序。我想要做的也是使用相同的公式生成接下來的 2 列。第 3 列用於計算基於用戶 ID 的唯一操作數，第 4 列用於計算基於用戶名的唯一操作數。我可以做一個單獨計算唯一性的公式，但理想情況下，我希望它與前 2 列一起使用。
非常感謝任何幫助。<

方法 1:
Try the following formula in cell A10 or any free cell except in columns F,G and H:
=arrayformula({query({F3:F,F3:F},"select Col1,count(Col2) where Col1<>'' group by Col1 label count(Col2) 'Total'",1),iferror(vlookup(query(query({F3:F,F3:F},"select Col1,count(Col2) where Col1<>'' group by Col1 label count(Col2) 'Total'",1),"select Col1"),query(query({F3:G,G3:G},"select Col1,Col2,count(Col3) where Col1<>'' group by Col1,Col2 label count(Col3) 'Total'",1),"select Col1,count(Col2) group by Col1 label count(Col2) 'Unique (for id)'",1),2,0)),iferror(vlookup(query(query({F3:F,F3:F},"select Col1,count(Col2) where Col1<>'' group by Col1 label count(Col2) 'Total'",1),"select Col1"),query(query({F3:F,H3:H,H3:H},"select Col1,Col2,count(Col3) where Col1<>'' group by Col1,Col2 label count(Col3) 'Total'",1),"select Col1,count(Col2) group by Col1 label count(Col2) 'Unique (for name)'",1),2,0))})
To get sorted (by column 2) result, try:
=arrayformula({query({F3:F,F3:F},"select Col1,count(Col2) where Col1<>'' group by Col1 order by count(Col2) desc label count(Col2) 'Total'",1),iferror(vlookup(query(query({F3:F,F3:F},"select Col1,count(Col2) where Col1<>'' group by Col1 order by count(Col2) desc label count(Col2) 'Total'",1),"select Col1"),query(query({F3:G,G3:G},"select Col1,Col2,count(Col3) where Col1<>'' group by Col1,Col2 label count(Col3) 'Total'",1),"select Col1,count(Col2) group by Col1 label count(Col2) 'Unique (for id)'",1),2,0)),iferror(vlookup(query(query({F3:F,F3:F},"select Col1,count(Col2) where Col1<>'' group by Col1 order by count(Col2) desc label count(Col2) 'Total'",1),"select Col1"),query(query({F3:F,H3:H,H3:H},"select Col1,Col2,count(Col3) where Col1<>'' group by Col1,Col2 label count(Col3) 'Total'",1),"select Col1,count(Col2) group by Col1 label count(Col2) 'Unique (for name)'",1),2,0))})
方法 2:
use:
=ARRAYFORMULA(QUERY({F3:H,
IF((G3:G<>"")*(COUNTIFS(F3:F&G3:G, F3:F&G3:G, ROW(G3:G), "<="&ROW(G3:G))=1), F3:F&G3:G, ),
IF((H3:H<>"")*(COUNTIFS(F3:F&H3:H, F3:F&H3:H, ROW(H3:H), "<="&ROW(H3:H))=1), F3:F&H3:H, )},
"select Col1,count(Col1),count(Col4),count(Col5)
where Col1 !=''
group by Col1
order by count(Col1) desc
label count(Col1)'Total',
count(Col4)'Unique (for id)',
count(Col5)'Unique (for name)'", 1))
