Based on Column Day concatenated with Date as Heading

Question

I have the data from my table as shown below

╔═════════╦════════════╦═════════════╗
║ PROD_ID ║ START_DATE ║ TOT_HOURS   ║
╠═════════╬════════════╬═════════════╣
║ PR220   ║ 19-Sep-17  ║ 0           ║
║ PR2230  ║ 19-Sep-17  ║ 2           ║
║ PR9702  ║ 19-Sep-17  ║ 3           ║
║ PR9036  ║ 19-Sep-17  ║ 0.6         ║
║ PR9036  ║ 18-Sep-17  ║ 3.4         ║
║ PR9609  ║ 18-Sep-17  ║ 5           ║
║ PR91034 ║ 18-Sep-17  ║ 4           ║
║ PR7127  ║ 18-Sep-17  ║ 0           ║
╚═════════╩════════════╩═════════════╝

Based on the START_DATE, could it be possible to have headings with Day concatenated with Date?

Expected output is

╔═════════╦════════════╦════════╦════════╦═══════════╗
║ PROD_ID ║ START_DATE ║ MON-18 ║ TUE-19 ║ TOT_HOURS ║
╠═════════╬════════════╬════════╬════════╬═══════════╣
║ PR220   ║ 19-Sep-17  ║        ║ 0      ║ 0         ║
║ PR2230  ║ 19-Sep-17  ║        ║ 2      ║ 2         ║
║ PR9702  ║ 19-Sep-17  ║        ║ 3      ║ 3         ║
║ PR9036  ║ 19-Sep-17  ║        ║ 0.6    ║ 0.6       ║
║ PR9036  ║ 18-Sep-17  ║ 3.4    ║        ║ 3.4       ║
║ PR9609  ║ 18-Sep-17  ║ 5      ║        ║ 5         ║
║ PR91034 ║ 18-Sep-17  ║ 4      ║        ║ 4         ║
║ PR7127  ║ 18-Sep-17  ║ 0      ║        ║ 0         ║
╚═════════╩════════════╩════════╩════════╩═══════════╝

Answer 1

Not without using dynamic SQL to make the query.

But if you are willing to hardcode the values then:

SQL Fiddle

Oracle 11g R2 Schema Setup:

CREATE TABLE PROD_TIMINGS( PROD_ID, START_DATE, TOT_HOURS ) AS
SELECT 'PR220',   DATE '2017-09-19', 0 FROM DUAL UNION ALL
SELECT 'PR2230',  DATE '2017-09-19', 2 FROM DUAL UNION ALL
SELECT 'PR9702',  DATE '2017-09-19', 3 FROM DUAL UNION ALL
SELECT 'PR9036',  DATE '2017-09-19', 0.6 FROM DUAL UNION ALL
SELECT 'PR9036',  DATE '2017-09-18', 3.4 FROM DUAL UNION ALL
SELECT 'PR9609',  DATE '2017-09-18', 5 FROM DUAL UNION ALL
SELECT 'PR91034', DATE '2017-09-18', 4 FROM DUAL UNION ALL
SELECT 'PR7127',  DATE '2017-09-18', 0 FROM DUAL;

Query 1:

SELECT PROD_ID,
       START_DATE,
       CASE START_DATE WHEN DATE '2017-09-18' THEN TOT_HOURS END AS "MON-18",
       CASE START_DATE WHEN DATE '2017-09-19' THEN TOT_HOURS END AS "TUE-19",
       TOT_HOURS
FROM   PROD_TIMINGS

Results:

| PROD_ID |           START_DATE | MON-18 | TUE-19 | TOT_HOURS |
