I don't know whether you can do that urgently, but - perhaps a somewhat slower approach might help.

What do you call "dynamically grouping columns"?

from an insurance table... which has let say

assured_name / premium_payments / and date_payment are the columns

ex. sample data....

edward 400 01-02-07
edward 300 01-02-08
john 100 01-02-08
mark 200 01-02-08

then the user will input 2 dates which will serve as the data range.... so if the user will input 01-02-07 and 01-10-08

will display all records between the two dates but the premium_payments must be sum up and assured name must be grouped so output will be

edward 700
john 100
mark 200

this is easy in report but in forms how can i do this....
i already than this in report but the client also want to have preview of data in form....

i have done this in report already...

the sql is


select assured_name , sum(premium_payments) as premium_payments from table where date_payment between :date1_param and :date2_param group by assured_name order by assured_name

and this worked properly but the client wants it to be previewed first in the form....

In that case, a VIEW (and form's data block based on this view) might be a solution.

Data range can be used in the DEFAULT WHERE clause set by the SET_BLOCK_PROPERTY built-in.

so examine the table above ..... then how will grouped that in a view where ...

edward 400 01-02-07
edward 300 01-02-08

so if you group this in a view

this will be the output

edward 700

the problem is what if the user only input this date range
01-02-07 and 12-12-07 so the output must only be

edward 400

that will be the problem if you will create a view because you dont know yet the input of the user....

What your problem really is? It has been said that you can define your restriction on block's where clause. Have you tried using view?

Also, your block data can be from query should you don't want to create a view.

ok lets start with creating a view .... if you will group the records above in a view using assured name and sum(premium payments) you must not include the date payment ... because if you include the date it will not be grouped properly ...

so how in this earth are you going to search for date range...


so if your code is this.. in view

select assured_name , sum(premium_payments) as premium_payments from table group by assured_name

then the output will be...


edward 700
john 100
mark 200



so there is no way now that the user will be able to enter the date range.. if we will not include the date

.. but if you include date in our view the output will not be grouped properly it will be like this.


edward 400 01-02-07
edward 300 01-02-08
john 100 01-02-08
mark 200 01-02-08

just the same as the table ...

if im going to use the where clause property for the date... this will be the output.....

let say date 1 and date 2 are..... 01-02-06 to 01-02-09


edward 400 01-02-07
edward 300 01-02-08
john 100 01-02-08
mark 200 01-02-08

what the client wants is..... the output should be grouped... like this...

edward 700
john 100
mark 200

but remember if the date ranges are..... 01-01-08 to 01-02-09 it must be like this....


edward 300
john 100
mark 200

why? because the first record is not covered by the date range gets?

actually i already found the solution for this just an hour ago... by creating a temporary table... when the user clicks the search button the temp table will be truncated first and populated by data based on the date ranges.......


i just want to know if there are other possible ways to solve this...

and i guess this will be not possible in using view...that is in my opinion but if you have ways to do this using view i want to know...

In view? Search for materialized view, but I think it still won't do. For that problem where you have to channel your data, the best thing is to have a temporary table which you have did.

Another thing to do is to create a cursor, and populate your block with that data from cursor. I think your block here is not a DB block.

I have no idea what a "pagie in pex" might be; however, would you (xpact83) please discuss it with Wency via private messaging system, or in Community hangout forum, or elsewhere? Now it's been the third time you insist on the same question (obviously, no answer so far).
