Question

I’m using Oracle. My sql returns a column like this

Name:
John Smith
David Lee
…

If I do Order by Name, it will order by first name. How do I order by Last name? If I do Order by Lastname, Firstname oracle returns invalid identifiers. I tried substr, instr but it doesn’t work. I know the sql is tedious but just want the data to quickly fix this issue.

First, in order to sort by LastName, it needs to be one of the columns you return in each of the queries in your Union All. Second, you can greatly simplify your query by using a common-table expression. Third, do not use the comma delimited syntax for Joins (e.g. From TableA, TableB, TableC…). Instead use the ISO Join syntax.

With RootQuery As
    (
    Select MeetingID
        , FirstName || ' ' || LastName AS Name
        , LastName
        , CASE WHEN RSVP = 1 THEN 1 ELSE NULL END AS Yes
        , CASE WHEN RSVP = 0 THEN 1 ELSE NULL END AS No
        , CASE WHEN RSVP = 2 THEN 1 ELSE NULL END AS Phone
        , CASE WHEN RSVP = -1 THEN 1 ELSE NULL END AS No_Reply
        , MysteryTable0.Response1
        , MysteryTable1.Response2
        , Note
        , groupname      
      From Attendance A
        Join Allusers As B
            And B.MemberId = A.PersonId
        Join MembershipGroups As M
            And M.MemberId = B.MemberID
        Join    (
                SELECT TD.MEMBERID AS MEM0
                    , Response AS Response1
                FROM TRACKINGDETAILS TD, ALLUSERS U
                Where TD.MEMBERID = U.MEMBERID 
                    And TD.TRACKINGID = 64
                ) MysteryTable0
            On MysteryTable0.Mem0 = B.MemberId

        Join    (
                SELECT TD.MEMBERID AS MEM1
                    , Response AS Response2
                FROM TRACKINGDETAILS TD, ALLUSERS U
                Where TD.MEMBERID = U.MEMBERID 
                    And TD.TRACKINGID = 65
                ) As MysteryTable1
            On MysteryTable1.Mem1 = B.MemberId
        Where Meetingid = :1
        )
Select MeetingId, Name, LastName, Yes, No, Phone, No_Reply
    , Response1, Response2
    , Note, GroupName
From RootQuery
Union All
Select Null, 'Total', LastName, SUM(Yes), SUM(No), SUM(Phone), SUM(No_Reply)
    , TO_CHAR(SUM(Response1))
    , TO_CHAR(SUM(Response2))
    , NULL, Groupname 
From RootQuery
Group By GroupName
Union All 
Select Null, 'Grand Total', LastName, SUM(Yes), SUM(No), SUM(Phone), SUM(No_Reply)
    , TO_CHAR(SUM(Response1))
    , TO_CHAR(SUM(Response2))
    ,NULL, ' '
From RootQuery
Group By ???
Order By GroupName Desc, LastName Asc, Name Asc

Btw, the last query will probably have a problem in that it did not have a Group By (which I denoted with Group By ???) but you are using aggregate functions.
