    I am making a simple select query. I want to compare 2 values and if one is
    bigger than the other, then I want my selection to be limited by that. The
    problem seems to be that one of the values is an expression so it won't let
    me compare it to the other. I know I could make an additional query that adds
    the where clause but was wondering if I can do this without doing that.
    Here's my SQL:

    SELECT tblMutualcustomers.Customer,
    tblMutualcustomers.AverageDaysBetweenPickups,
    Max(tblinvoiceorderlinemaketable.ShipDate) AS MaxOfShipDate,
    Date()-[maxofshipdate] AS Dayssincelastpickup,
    tblinvoiceorderlinemaketable.InvoiceLineItemRefFullName, "Computer Generated"
    AS RequestType
    FROM tblinvoiceorderlinemaketable RIGHT JOIN tblMutualcustomers ON
    tblinvoiceorderlinemaketable.CustomerRefFullName = tblMutualcustomers.Customer
    GROUP BY tblMutualcustomers.Customer,
    tblMutualcustomers.AverageDaysBetweenPickups,
    tblinvoiceorderlinemaketable.InvoiceLineItemRefFullName, "Computer Generated"
    HAVING (((tblinvoiceorderlinemaketable.InvoiceLineItemRefFullName) Like
    "Mutual:pallet Pickup"));

    I want records to show up where the expression
    [dayssincelastpickup]>=[tblMutualcustomers].[AverageDaysBetweenPickups]

    Thanks!

Since you're here... we have a small favor to ask...

More people are visiting & reading SPN than ever but far fewer are paying to sustain it. Advertising revenues across the online media have fallen fast. So you can see why we need to ask for your help. Donating to SPN's is vote for free speech, for diversity of opinions, for the right of the people to stand up to religious bigotry. Without any affiliation to any organization, this constant struggle takes a lot of hard work to sustain as we entirely depend on the contributions of our esteemed writers/readers. We do it because we believe our perspective matters – because it might well be your perspective, too... Fund our efforts and together we can keep the world informed about the real Sikh Sikhi Sikhism. If everyone who writes or reads our content, who likes it, helps us to pay for it, our future would be much more secure. Every Contribution Matters, Contribute Generously!
