The function ADD_DAYS, ADD_HOURS, ADD_MINUTES, ADD_SECONDS, ADD_YEARS exist on DB2 LUW, but not on DB2 for i. However the function ADD_MONTHS is implemented on DB2 for i. Adding those missing functions on DB2 for i would be very useful to manage temporal datas provided by different sources.

    This enhancement was delivered in May 2023 with IBM i 7.5 PTF Group level 4 and IBM i 7.4 PTF Group level 25.

    The ADD_DAYS, ADD_HOURS, ADD_MINUTES, ADD_SECONDS, and ADD_YEARS scalar functions have been added for Db2 for i.
    These functions are equivalent to the existing date and time arithmetic, but provide additional compatibility with the Db2 family.

    You can read about them on a new fact page here:
    And in IBM Documentation here:

    what is the advantage of the future function

    ADD_DAYS(current_date, 1)

    versus available syntax

    values(current_date +1 days)


    same question for YEARS, MONTH, HOUR, MINUTE, SECOND

    IBM will use this Idea as input to planning, but no commitment is made or implied. This Idea will be updated in the future if IBM implements it.
