Hi,
I've got a stack of tasks to show in a list.
Every task has a timestamp X that may be NULL or a date. It contains
the date when this tasks should be done.
Sometimes it has date and the time-part, too.
The list should be like this:
1) X sometime today should come first in ascending time order.
2) X in the past should show up after (1) in descending order so that
not so long back dates come first
3) X = NULL
4) X sometime in the future
The point is, I like to do the skeduled tasks for today as planned. = (1)
Those allready lost appointments should not defer those today that are
still in time but I like to get them after the today-tasks in an order
where there is a chance that a nearer lost appointment might be still
rescued even though it's a bit late.
The dates longer back might be lost for good anyway so they can wait a
bit longer. = (2)
Provided I get through (1) and (2) I'd venture the unknown where there
wasn't a date until now. = (3)
Well, and future dates will be minded when their time is there. = (4)
For now I do this by having a sorting-column in the tasks-table that
gets updated in 4 steps where my application has to select every group
(1) - (4) then sequentially walk through the recordset and update the
sort-order-column by a counter.
Later I sort ascending by the sort-order-column.
It kind of works but I consider it ugly.
Could you provide a clever solution?
