我的数据进入我的系统（格式无法更改），如下所示：
Row, C001, C002, C003, to C029 (Columns for FY values)
1, Name, 0910, 1011
2, Eqt1 (Speed), 60, 100
3, Eqt1 (Cost), 20, 30
4, Eqt2 (Speed), 50, 60
5, Eqt2 (Cost), 30, 45
我需要将其更改为：
Name, Start_Date, End_Date, Speed, Cost
Eqt1, 01-APR-2009, 30-MAR-2010, 60, 20
Eqt1, 01-APR-2010, 30-MAR-2011, 100, 30
Eqt2, 01-APR-2009, 30-MAR-2010, 50, 30
Eqt2, 01-APR-2010, 30-MAR-2011, 60, 45
我可以使用子选择分割日期，其中row = 1。 我可以替换名称中的（速度）（成本）。 但我无法做到。
WITH survey_query AS (
SELECT *
FROM tbl_data
)
SELECT (CASE WHEN upper(sq.c001) LIKE '%FLEET SIZE%' THEN TRIM(REPLACE(upper(sq.c001), 'FLEET SIZE', ''))
WHEN upper(sq.c001) LIKE '%FLYING HOURS%' THEN TRIM(REPLACE(upper(sq.c001), 'FLYING HOURS', ''))
END) equipment_name
,(select TO_DATE(2000+dbms_lob.substr(c002,2,1)||'0101', 'yymmdd') FROM survey_query where line = 1) start_date
,(select TO_DATE(2000+dbms_lob.substr(c002,2,4)||'0330', 'yymmdd') FROM survey_query where line = 1) end_date
,(case when UPPER(sq.c001) like '%FLEET SIZE%' THEN sq.c002 END) fleet_size
,(case when UPPER(sq.c001) like '%FLYING HOURS%' THEN sq.c002 END) flying_hours
FROM survey_query sq
WHERE line > 1
UNION
SELECT (CASE WHEN upper(sq.c001) LIKE '%FLEET SIZE%' THEN TRIM(REPLACE(upper(sq.c001), 'FLEET SIZE', ''))
WHEN upper(sq.c001) LIKE '%FLYING HOURS%' THEN TRIM(REPLACE(upper(sq.c001), 'FLYING HOURS', ''))
END) equipment_name
,(select TO_DATE(2000+dbms_lob.substr(c003,2,1)||'0101', 'yymmdd') FROM survey_query where line = 1) start_date

,(case when UPPER(sq.c001) like '%FLYING HOURS%' THEN sq.c003 END) flying_hours
FROM survey_query sq
WHERE line > 1;
有什么想法吗？我必须有一个更好的方法，因为我有28列的数据，所以27＆＃34;工会＆＃34;

它不是很优雅，因为它使用了旧式的旋转，但我无法通过11g PIVOT功能来解决这个问题：

感谢您的回答，他们让我思考。也很抱歉在回复中等了很长时间，我已经工作了2周。
