my problem is that in a cross table report, I want to display all the
day for a specific month. For example, I would like to know for all
project (line) how many hours I spent for each day (colomn). I get all
good values for that but because I have not work saturday, the colomn
doesn't appear because the're is no record for that day in the
database.

               1     2    3   9  12
programming    6     4    8   4   1
analysing      1     3    0   3   6

I would like to display that (below) without creating a dumb table
with all day for a month and make an outer join with it. Is that
possible?

               1     2    3   4   5   6   7   8   9   10   11   12
