我的表格如下：
[Table A][1]
B_NUMBER_COUNTRY OUTGOING_CARRIER MINUTES
CAN A 1,045.71
CAN B 7.98
CAN C 973.52
FRA A 566.19
FRA B 521.52
FRA C 27.03
FRA D 549.14
FRA E 0.21
USA A 32.57
USA B 303.17
USA C 9,837.53
USA D 3.91
USA E 0.07
USA F 2,469.00
USA G 67.68
USA H 0.37
USA I 933.72
我需要根据分钟总和对b_number_country进行排名。
在上述情况下，美国的总分钟数为13K，CAN为2K，FRA为1.6K。所以排名应该是USA - 1，CAN - 2和FRA - 3.通过添加排名列，它应该显示如下：
[Table A (rank)][2]
B_NUMBER_COUNTRY OUTGOING_CARRIER MINUTES RANK
CAN A 1,045.71 2
CAN B 7.98 2
CAN C 973.52 2
FRA A 566.19 3
FRA B 521.52 3
FRA C 27.03 3
FRA D 549.14 3
FRA E 0.21 3
USA A 32.57 1
USA B 303.17 1
USA C 9,837.53 1
USA D 3.91 1
USA E 0.07 1
USA F 2,469.00 1
USA G 67.68 1
USA H 0.37 1
USA I 933.72 1
我无法获得正确的查询来执行此操作。每次尝试，它都包括b_number_country和outgoing_carrier作为排名的一部分。
答案 0 :(得分：3)
根据评论编辑：
您需要两个步骤，先计算分钟总和，然后对它们进行排名：
SELECT ...,
DENSE_RANK()
OVER (ORDER BY sumMinutes DESC) -- must be DENSE_RANK
FROM
(
SELECT b_number_country, interval_of_day, outgoing_carrier,
SUM (call_duration)/60 AS Minutes,
SUM (call_count) AS attempt,
SUM (answered_count) AS answered,
SUM (seizure_count) AS seizure,
SUM(start_call_count) AS Count_X,
SUM(ner_count) AS NER_COUNT,
SUM(SUM (call_duration)/60)
OVER (PARTITION BY B_NUMBER_COUNTRY) AS sumMinutes
FROM bm_archived_cdr
WHERE call_direction = 'O'
AND call_date = DATE '2016-04-21'
GROUP BY b_number_country, interval_of_day, outgoing_carrier
) dt;
