Allowing additional data to be added after a join with blank rows

I've got a left join query that returns the correct number of rows (equal to the left table), but because the right table is empty, there are no corresponding rowid's. How can I add the rowid (RecNum should be the same value) to the empty table so that I can add data to the resulting dataset? Here's the query:

select
  Week01.RowID    as RowID,
  Week01.WRecNum  as WRecNum,
  Week01.RecNum   as RecNum,
  Week01.UserName as UserName,
  Week01.Day1Reg  as Day1Reg,
  Week01.Day1OT   as Day1OT,
  Week01.Day2Reg  as Day2Reg,
  Week01.Day2OT   as Day2OT,
  Week01.Day3Reg  as Day3Reg,
  Week01.Day3OT   as Day3OT,
  Week01.Day4Reg  as Day4Reg,
  Week01.Day4OT   as Day4OT,
  Week01.Day5Reg  as Day5Reg,
  Week01.Day5OT   as Day5OT,
  Week01.Day6Reg  as Day6Reg,
  Week01.Day6OT   as Day6OT,
  Week01.Day7Reg  as Day7Reg,
  Week01.Day7OT   as Day7OT
from
  "Project List"
left join
  Week01
on
  "Project List".RecNum = Week01.RecNum
and 
  Week01.UserName = "JustMe"
