GROUP BY CASE语句输出

Question

如何更改下面的脚本，以便我可以执行GROUP BY YR，QTR，CODE值QTR_PCT给出的值以获得我想要的输出？

CREATE VIEW REPORTS.MY_VIEW 
(YR, QTR, QTR_PCT, CODE) 
AS 
SELECT YR, QTR 
, CASE WHEN PCTPERF>=85 THEN ROUND(AVG(PCTPERF)) 
    ELSE NULL 
    END QTR_PCT 
, CODE 
FROM ANOTHER_VIEW 
GROUP BY YR, QTR, PCTPERF, CODE 
ORDER BY CODE ASC; 

实际输出：（我没有包括列QTR_PCT）

+------+-----+------+ 
| YR | QTR | CODE | 
+------+-----+------+ 
| 2012 | 1 | 1039 | 
| 2012 | 1 | 1039 | 
| 2012 | 1 | 1039 | 
| 2012 | 2 | 1039 | 
| 2012 | 2 | 1039 | 
| 2012 | 2 | 1039 | 
+------+-----+------+ 

所需的输出：（我没有包括列QTR_PCT）

+------+-----+------+ 
| YR | QTR | CODE | 
+------+-----+------+ 
| 2012 | 1 | 1039 | 
| 2012 | 2 | 1039 | 
+------+-----+------+

我不知道我理解你的问题，但也许这可以帮助，请尝试：

SELECT YR, qtr, code,max(qtr_pct) aa 
FROM (
SELECT YR, qtr, code, pctref, CASE WHEN pctref >= 85 THEN round(avg(pctref) over (partition BY YEAR, qtr, code)) 
    ELSE NULL END qtr_pct 
FROM ANOTHER_VIEW) t 
GROUP BY YR, qtr, code;
