收到一個錯誤而執行蜂房查詢涉及在FROM子句

Question

子查詢我與模式的表，如下圖所示：

CREATE TABLE Table1 (`membertype` varchar(1)); 

INSERT INTO Table1 (`membertype`) 
VALUES 
    ('Y'),('H'),('U'),('W'),('W'),('W'),('H'),('H'),('U'), 
    ('U'),('P'),('P'),(''),('P'),('P'),('P'),(''),('W'), 
    ('Y'),('Y'),('Y'),('H'),('D'),('D'),('D'),('D'),('H'), 
    ('W'),('W'); 

我試圖做到的，是讓每一個計數在列中輸入以及它們的百分比與列中類型的總數。

我測試在MySQL中下面的查詢，並得到所期望的結果：

select (case when m.membertype='Y' then 'Young Adult' 
    when m.membertype='H' then 'Head' 
    when m.membertype='W' then 'Spouse' 
    when m.membertype='P' then 'Aged Parent' 
    when m.membertype='U' then 'Unknown' 
    when m.membertype='D' then 'Deceased' else 'No Match' end) as type, 
    count(*) as typecount, 
    count(*)/t.total*100 as percentage from Table1 as m, 
    (select count(*) as total from Table1) as t group by membertype; 

type  typecount percentage 
No Match  2   6.8966 
Deceased  4   13.7931 
Head   5   17.2414 
Aged Parent 5   17.2414 
Unknown  3   10.3448 
Spouse  6   20.6897 
Young Adult 4   13.7931

相同的查詢在HIVE失敗，並在下面錯誤：

select (case when h.member='Y' then 'Young Adult' 
when h.member='H' then 'Head' 
when h.member='W' then 'Spouse' 
when h.member='P' then 'Aged Parent' 
when h.member='U' then 'Unknown' 
when h.member='D' then 'Deceased' else 'No Match' end) as type, 
count(*) as typecount, 
count(*)/t.total*100 as percentage from hhinfo as h, 
(select count(*) as total from hhinfo) as t group by member; 


FAILED: SemanticException [Error 10025]: Line 1:277 Expression not in GROUP BY key 'total' 

我在這裏錯過了什麼？任何幫助，將不勝感激。

Answer 1

嘗試顯式添加total到group by clause

...as t group by member, total
