Nicht ohne dynamisches SQL für die Abfrage zu verwenden.
Aber wenn Sie bereit sind, die Werte fest zu codieren, dann:
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;
Abfrage 1 :

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
