[JHS10.1.3] Date problem

Question

Running into a date problem for a forms migration.
I have a date field in the database, normal date field.
The users want to be able to search on partial dates.
So adding a between on this field will only generate two date selectors, which is not what they want.
The format is like a year field, week field, day field.
I could modify the query to return three extra numeric fields which convert the date to the right format ('yyyy', 'wi', 'dd' ) and then to number and generatie 3 between fields for this.
This will generate the right layout, 6 input fields for a year from/to week from/to day from/to
But the query will be like (year between x and x) and (week between x and x) and day (between x and x)
This will not produce the right results.
What is possible is a string manipulation of the whereclase in the method getViewCriteriaClause()
And see if any/all of the fields are filled and build the query there, but this is not a 'clean' solution.
Any idea on how I can solve this? Basicly a date field in the database, user wants to search that date field on year/week/day between year/week/day or a partial of that.
This is the way it used to be in the forms application so I really want to give the same functionality with ADF.

Not sure if I completely understand what you said, but this is what I did ( it seems to work )
All my viewobjects extends a new superviewobjectimp, this class has just 2 setters and getters, one for the datefield I want to search on and one for the partial name I gave the three attributes (<fixed name>Year <fixed name>Week <fixed name>Day).
In the advancedSearch, in the loop trough the attributes I cast the viewobject to this superviewobjectimp. I can now check if the attribute contains the partial name. If this is the case I build my own string and add it to the viewCriteriaMap.
One odd thing I found here is that it refuses to let me add a string like
between to_date( '<startdate>', 'yyyy-mm-dd' ) and to_date( '<enddate>', 'yyyy-mm-dd' )Because if I do this, for some reason the attribute name will be wrapped in a to_char!
If I just leave:
between '<startdate>' and '<enddate>'It works, but I dont feel really safe about that, I would rather use the datecast to be sure.
Any idea how this can be done?
I also used the java Calendar class to transform a yyyy-iw-d to a yyyy-mm-dd because it seems I cant use 'iw' in a to_date(....). This also solved a problem with partial dates, java will autocomplete them for me.
In other words if I only supply the year 2005 to 2006 it will auto search from 2005-1-1 - 2006-1-1, same for weeks.
I have a lot of viewobjects which will require this, I'm trying to make it as solid as I can.
Any suggestions?
