Editable crosstab querie

4 New Member
Is it possible to create form containing an editable crosstab querie?

The only way I can think of is to create a temporary table where the results of the crosstab querie are stored, then presented in a form for edit purposes and when closing the form 'translating' the temporary table back into the original one.

(simplified) Example:

Table:
- id, week, number
1 1 a
1 2 b
1 3 c
2 1 d
2 3 e

Crosstab:
- id, week1, week2, week3
1 a b c
2 d _ e

In this crosstab the a,b,c,d,e and _ should be editable.

In the current solution you can select a row in the crosstab form in order to open a form presenting the original table (filtered on id), but direct editing is highly appreciated.

You can't have a directly editable crosstab. By design, crosstabs are meant to summarize data.

Hmm, in a case like this I sometimes "drop" the normalization rules and use for every week a fixed field in my table. (So Week1 to Week53)
This will allow easy updates, but will require additional tricks to use the data in other ways...

This solution came to mind, but this will involve a lot of calculations.

For your information, it involves an activity week planning where each activity can take place in different weeks and can last for over a year. To denormalize the weeknumbers I probably will have to use a relative week number to keep the table correct over the years (another solution is to define the week from today up to the next 5 years or so - implying over 250 colums, but this is not very flexible).
Other functionalities in my program imply adding up the activities hours for a given week. This will then imply a difficult algorithm because you have to use different weeknumbers indicating the same week.

Perhaps using a crosstab query to fill a temporary table, having the format of the results of the query and edit in this table is to only feasible solution. Of course then I will need an algorithm to update the original activity table with the results from the temporary one. But this is a less complicated algorithm and futhermore this is to be programmed in one place.

I will keep this question open for the next few days, to give people the chance to come up with other ideas ;-) If nothing is coming up, I will try the temporary variant.

Operating in A97. I didn't receive much of a response conserning Pivot tables in Access. Pivot tables are nice, but a CrossTab will work for me too. Using a Pivot table, one is actually launching Excel for data viewing. I'd prefer the user stay in Access. Creating dynamic crosstab queries is pretty simple. The problem is that the column count may shrink or grow depending on the filter.
