Question

LOV with select query and order by clause using P_ITEM

Asked by: skahlert2010

Hello guys! I have a special request that I'm focussing on. I have a couple of select lists in my application that contain tree species.
On the first page the user has the opportunity to assign a ranking to the respective tree species. The database column storing that information is named INT_BEDEUTUNG.

Instead of using that order by clause continously I want to be able to change the order by definition using two buttons. One is used to order alphabetically (column BA_LANG) and one is used to order by the field INT_BEDEUTUNG.

Hence I tried to bind an item (P6_SORT) via a button, assigning it to either BA_LANG or INT_BEDEUTUNG.

The tree species select lists in my reports are based on LOVs using the following query:

I thought that if :P6_SORT conatins the value BA_LANG or INT_BEDEUTUNG, the selct list would be ordered accordingly. Unfortunately it doesn't, although P6_SORT is not empty?

Do you have an idea what I am doing wrong or how to change the order by clause for that query for the whole application?

I'd appreciate your interesting answers and thoughts!

Best regards,

Sebastian

Is it Oracle Forms application ?

 

by: skahlert2010Posted on 2009-09-17 at 01:57:41ID: 25353999

Hello Henka! No, it's Oracle application express and not Oracle Forms.

The trick that did what I was looking for, is to remove the ' ' from the item value.

Nevertheless I have one more question. I am using 2 html buttons on page 1 with URL-redirect in order to set the item on a specific page. This was for testing purposes only.
Now I just want to set the attribute or value on page one where the respective buttons are placed.
I have other navigating buttons on the same page, which when clicked, bind items on the target page. These should be used throughout the application to forward the item value for P_SORT.

Now the question is - how can I bind an item on page 1 without being redirected? Is there a javascript routine or a simple trick that does the trick???

Thanks again and best regards,

Sebastian

Oh, I am sorry, but I cannot help you, I am not familiar with the Oracle application express.
I hope someone else will help you.
