Date formula that adds hours and changes date

    Hi,

    I'm in need of a formula that would account for next day change. I am working on a view that adds 2 hours (due to changing time zone) to the "create date". However, if adding the 2 hours to the create date falls into the next day, the DATE does NOT change. How can I account for that? Im using

    dateadd(hh,2)

    to add the date, but I'm not sure how to account for the next date if the time falls into that.

    The date does change or am I missing something?

    DECLARE @Date DATETIME = '2019-07-19 22:42:45.880'
    SELECT DATEADD(hh, 2, @Date)

    Result:

    2019-07-20 00:42:45.880

    One thing that I can say for certain is that the DATEADD function takes 3, not 2, parameters.  See the post that rVadim posted on this thread.

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
