Question

I have a parameter called pmday which I want to, when it is enetered, check if the day is on a saturday or sunday, and, if so, show the monday after.

I am relatively new to mySQL and I am running a SELECT statement to use pmday in other ways. Can I create a column which will show the monday after, only if the day falls on a weekend?

Here is an example of what I have been trying (and failing) to do. Im not sure if this is just a problem of me not knowing how, functions within select statements not being allowed, or general formatting and use of commas.

Thank you!

SELECT
    pmday AS EnteredDate,
    IF DateFormat(pmday, '%W') = 'Saturday' then
         Date_Add('pmday', INTERVAL 2 DAY) AS FollowingMonday
    Else If  DateFormat(pmday, '%W') = 'Sunday'  then
         Date_Add('pmday', INTERVAL 1 DAY) AS FollowingMonday
    END IF;

Answer 1

SELECT
    pmday AS EnteredDate,
    CASE Date_Format(pmday, '%W')
        WHEN 'Saturday' THEN Date_Add(pmday, INTERVAL 2 DAY)
        WHEN 'Sunday' THEN Date_Add(pmday, INTERVAL 1 DAY)
        ELSE pmday
    END AS FollowingMonday
