Лявото присъединяване не дава нулевите стойности в таблицата sql

Има няколко проблема, които съм посочил по-долу

  1. Използвали сте това като INNER JOIN както следва, но ON условие се състои от колона от таблица:PAY_PAYROLL_ACTIONS което ще направи условието невярно, ако няма данни за служител в PAY_PAYROLL_ACTIONS таблица.

    JOIN PAY_TIME_PERIODS PTP ON ( PPA.EARN_TIME_PERIOD_ID = PTP.TIME_PERIOD_ID )

  2. Използвали сте следните 5 условия WHERE.

    • PPA.ACTION_TYPE IS NULL
    • TO_CHAR(NVL(PPA.EFFECTIVE_DATE, '2019-09-01'), 'YYYY-MM-DD') BETWEEN ( '2019-09-01' ) AND ( '2019-12-01' )
    • PPA.CONSOLIDATION_SET_ID = PCS.CONSOLIDATION_SET_ID
    • NVL(PPA.EFFECTIVE_DATE, TRUNC(SYSDATE)) BETWEEN PAYREL.START_DATE AND PAYREL.END_DATE
    • NVL(PPA.EFFECTIVE_DATE, TRUNC(SYSDATE)) BETWEEN PAPD.START_DATE AND PAPD.END_DATE

Тези условия също влияят върху крайния резултат въз основа на наличието на данните в таблицата PAY_PAYROLL_ACTIONS .Опитвам се да ви дам решението (вижте вградените коментари за описание на промяната) според познанията ми за тези таблици, както следва:
