Oracle 11g R2 Schema Setup:
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;
Query 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 |
