Generate list of working day according to rule defined.

  • I have table workingDates that has 3 columns

    wd:(type int ) This column has all working dates in int format for a year weekends and holidays are not included.

    fulldate (datatype date): same as wd but in date format.

    dayname : this contains weekdayname like monday,tuesday.

    I want to generate list of two dates for each month as per following rule.

    second friday of each month (if second friday is holiday for that month then that date would not be there workingDates.wd in this case i need previous working i,e thrusday or wednesday whatever is working day availble in table )

    Monday after third friday for each month ( in this case if monday is holiday i need next working day i.e tuesday or wednesday whatever is working day availble in table )

    I need your help to create the query in this scenario.

    output expected :

    year month rule_1_dates rule_2_dates

    2019 Jan 20190111 20190121

    and so on.......
