我想将一组数据分发到如下所示的表中：

RANGE(days)  No of days.       Amount
0-30            -                0

SQL Fiddle

Oracle 11g R2架构设置：

CREATE TABLE data ( SN, START_DATE, Details, TranAmt ) AS
  SELECT 1, DATE '2015-05-22', 'A', 448749.14 FROM DUAL UNION ALL
  SELECT 2, DATE '2015-09-22', 'B',   4883.02 FROM DUAL UNION ALL
  SELECT 3, DATE '2015-11-04', 'C',  45646.27 FROM DUAL UNION ALL
  SELECT 4, DATE '2016-04-26', 'D',  42861.99 FROM DUAL UNION ALL
  SELECT 5, DATE '2016-06-16', 'E',  23144.23 FROM DUAL UNION ALL
  SELECT 6, DATE '2016-07-27', 'F',  21913.70 FROM DUAL UNION ALL
  SELECT 7, DATE '2017-08-11', 'G',  61396.94 FROM DUAL UNION ALL
  SELECT 8, DATE '2017-11-30', 'H',  12659.92 FROM DUAL UNION ALL
  SELECT 9, DATE '2018-03-19', 'I',   4185.78 FROM DUAL;

查询1 ：

WITH end_date ( end_date ) AS (
  SELECT DATE '2018-06-30' FROM DUAL
),
ranges ( first, last ) AS (
  SELECT   0,   30 FROM DUAL UNION ALL
  SELECT  31,  180 FROM DUAL UNION ALL
  SELECT 181,  365 FROM DUAL UNION ALL
  SELECT 366, NULL FROM DUAL
)
SELECT NVL2(
         r.first,
         r.first || NVL2(
                      MAX( r.last ),
                      ' - ' || MAX( r.last ),
                      ' and above'
                    ),
         'Total'
       ) AS range,
       COUNT( d.sn ) AS "No of days",
       COALESCE( SUM( d.TranAmt ), 0 ) AS Amount
FROM   data d
       CROSS JOIN end_date e
       RIGHT OUTER JOIN ranges r
       ON (    d.start_date < e.end_date + 1 - r.first
           AND (  r.last IS NULL
               OR d.start_date >= e.end_date - r.last ) )
GROUP BY ROLLUP( r.first )
ORDER BY r.first

Results ：

|         RANGE | No of days |    AMOUNT |
|---------------|------------|-----------|
|        0 - 30 |          0 |         0 |
|      31 - 180 |          1 |   4185.78 |
|     181 - 365 |          2 |  74056.86 |
| 366 and above |          6 | 587198.35 |
|         Total |          9 | 665440.99 |
