Ikke uden at bruge dynamisk SQL til at lave forespørgslen.
Men hvis du er villig til at hardkode værdierne så:
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;
Forespørgsel 1 :
