Search some data in choise list .

Hi experts,
I have created one dashboard prompt in OBIEE 11.1.1.6g, and I am facing one issue that when I make use of 'SQL Results' in Choice List Values Area to union some values, I click search button and input start value, it will only filter one kind of data.
For example:
'SQL Results' in Choice List Values Area :
I input the following SQL:
SELECT "Time"."Per Name Half" FROM "Sample Sales Lite"
union
SELECT "Time"."Per Name Year" FROM "Sample Sales Lite"
Then when I click search in choise list, and input 2010 in start area. The result will only generate 2010, but not 2010 HY1 ,2010 HY2
Are you facing the same problem? Thanks.

Hi,
Sorry, it does not work.
I think it is the BUG .But I do not confirm it.
You can try to the same thing in your machine to check it based on my steps.
Based on SamppleApplite RPD applied by ORACLE.
1. New Dashboard Prompt->click green button to add new column
2. Select one column named 'Per Name Year'
3. Click pencil
4. Select Choice List in User Input Area.
5. Options->select SQL Result-> Input the following code
SELECT "Time"."Per Name Half" FROM "Sample Sales Lite"
union
SELECT "Time"."Per Name Year" FROM "Sample Sales Lite"
6. Click "OK" button to save it.
7. Test this prompt in bottom area, and click drop down, then click 'Search...'
8. Select 'Starts' in Name Area and input 2010, then click Search button
9. View the result , it will only generate 2010, not 2010 HY1 adn 2010 HY2

Input Combobox LOV as a Navigation List?

Hi OTN,
when I drag a datasource on a page and drop it as "Navigation - Navigation List" a selectOneChoice is created.
Is there an opportunity to use Input Combobox List of Value as a navigation list? I would really like to use its search and MRU ability.
I tried to drop an attribute as an Input Combobox LOV and change ListOperMode to "navigation" in Bindings - but I get NPE in oracle.adfinternal.view.faces.config.rich.RegistrationConfigurator
(BEA-000000).
Thanks.

How to create a multi column list item and select these values from a LOV

Hi all,
My requirements are:
1) create an LOV which holds the productno, productname and productprice fields (this is working)
2) at run time, select one record from LOV and populate the list/grid with this selected record values of productno, productname and productprice fields, so we are showing them on the form in the form of a table/grid (not working)
3) be able to select multiple records from LOV and be able to populate the list item with multiple records (not working)
4) have two more columns in the list/grid, for productquatity and total price (not wokring)
Please help me.
how can i create this grid or list in oracle
whats the possible way of acheiving this in oracle

If you use a list item to display multiple columns then you'll need to use a fixed-width font. You can achieve a similar look with proportional fonts by using a normal block and setting the fields' bevel to 'None'.
Each column in the LOV has a Return Item property (under Column Mapping Properties). Set this to a :block.item reference for each column to bring the data back into those referenced fields.
You can't select multiple records from an LOV. For this you will need to create your own form. Check the help for system.mouse_button_modifiers to see how to respond to Ctrl+click and Shift+click.
To add columns just modify the LOV's record group's query.

LOV an SQL : how to configure a select list to get all records

Hello,
I am using Oracle 10g with APEX 2.0.
Here is my question:
I have a report and I am using 3 text fields and a select list to search through a join of two tables. The select list is composed of a "list of values" and the parameter, which is used in the SQL-sentence, has a numeric value.
Result table after the join operation looks like this:
Field1 Field2 Field3 Field4 (By assuming the field3 is the one which used in the select list.)
21a this 1000 bn
21a that 1001 vb
33c thus 1012 ct
What I want to do is to set another parameter-value pair in the select list to let user choose the "ALL" of the mentioned items in the select list so that the search will return all the records without having taken this select list-field into consideration.
Is it possible to do it with LOV and SQL? Do I need any other functions? or configurations?
Thanks in advance,
Sedef

Hi user630478!
I always use a select list with submit and the option to get a NULL-Value for such things. To solve your problem do the following things:
1.) Create two named LOVs. One as you already did and another one for all values.
2.) Your select list with submit should be configured to show a NULL-Value e. g. it shows ALL with the value 0.
3.) Create two conditional branches that work together with your select list. One that show the normal results if a user has clicked on a normal value and the second should act only if a user has clicked on ALL.
4.) Write a process that switches the LOVs in your select list from one to the other. This process should only be fired if the second conditional branch has been actived.
Maybe if I understood right that's what you want to know.
yours sincerely

DYNAMIC LOV FOR SELECT LIST

hi to all,
i've a question regarding lov query based select list:
For a certain user i need that the lov display a list
if app_user = BACK_OFFICE I NEED THAT ther query on wich is populated the
select list is qry 1.
if app_user is another (consultant) i need query 2 for populating the select list
1) select name|| ' ' || fname D, id K from partner
2) select name|| ' ' || fname D, id K from partner WHERE UNAME=(:APP_USER)
Any solutions would be greatly appreciated.
Another solution would be to have 2 different apps (one for back-office, one for external consultant), but there i should always duplicate all changes to the second one, loosing a lot of time.
Now thinking as well to use hidden fields.
If not clear enough please ask me.
Thanx a lot.

I think one solution wold be to create two different named querys, one containing query 1 and the second query 2. Than u must create an Application Item(like a session variable) in wich u will store you condition. If you want to use the app_user variable u allready have it so you don't need to create it any more. On your page where u want to display the different select list u create two items, one with the query 1 as source and a second item(select list) having the source query 2. Then you must add a condition display on both of them like. Item one is displayed when Value of Item in expression 1 equals expression 2. And you pust :APP_USER in expression 1 and BACK_OFFICE in expression 2. And for the other item, that contains query 2, you put the opposite condition Value of item in expression 1 is not equal to expression 2, and expression 1 is :APP_USER and in expression 2 is BACK_OFFICE.
Hope this helps.

One select list with multiple LOV's (LOV based on how page was called)

APEX 4.0.2
I've a DML form page from a report on which I need a single select list item to have a differing LOV based on how the form page was called.
The calling page (report), contains an edit link column and a create button. Depending on which is selected, I wish the LOV for my select list item to change. The idea behind this is that if someone creates a new entry, I want to constrain the select list to a subset of rows of a table query populating the LOV. On the other hand, if an existing item is edited, I want the select list LOV containing all rows of a table query populating the LOV.
What I've tried...
- Duplicates of select list item each triggered to render based on an arbitrary value set when either "create" or "edit" are selected. This did not work because the item was part of DML and would not allow replication on the same page.
- Logic in the LOV sql statement controlling which sql was to be run based on an arbitrary value set when either "create" or "edit" are selected. This did not work as logic is not allowed in LOV sql statements.
Any thoughts? Many Thanks!

Hello Patrick!
Thanks for responding - Love your captcha plugin!
Anyway, these are the two dynamic LOV's. The first I have in play right now (when creating new records). I need to have the other for existing record modifications.
LOV #1
select stock_no d, stock_no r
from   [email protected]
where status like '%Awaiting Transfer%'
or     status like '%On Hold%'
order by 1LOV #2
select stock_no d, stock_no r
from   [email protected]
order by 1As I mentioned, I attempted to use plsql logic in the query to trigger one or the other based on a value set when the user either clicked an edit link or a create button but couldn't get the dynamic LOV to commit with that extra code in it.
Thanks!

Shorten LOV list in parameter field

Hi,
I have a quesiton regarding LOV. Say, if I define a parameter Employee_Last_Name as search condition for my report. Then I define list of values for Employee_Last_Name. Is there any way user can enter partial string to shorten LOV?
Thanks,
Amanda

Are we talking on different version of Discoverer? I am referring to Discoverer 4i. In both desktop or viewer version of Discoverer 4i, the LOV always show whole list of values even if you enter partial string and wild card. Please let me know if 9i or 10g correct this issue. Thanks.

Use of LOV (list of values) in UCM

Hi.
Does anybody know if this can be achieved in UCM?
Sooner we'll have to deal with huge lists (thousands of values) that could affect performance. Using LOV instead of selected list would suppose a great enhacement and a clear way for a user to search, avoiding him the difficulties that suppose handling with that kind of lists.
Thanks in advance.

Dependent Dynamic LOV lists in a table format

I have a screen where the user can enter multiple rows into a tabular layout.
Three columns have LOV's where the selection in the first LOV should restrict the list in the Second LOV which will restrict the list in the third LOV. I think I could manage it if it were a single row of data being captured, but how does one reference the previous fields selection in the next field when using multiple table rows.
I have a db table which I think can drive the process, but I'm not familiar with the method in which to handle it.
Table: id, LOV-1 -value, LOV-2 value, LOV-3 value
So when user selects from LOV-1, only those LOV-2 values associated with LOV-1 that the user selected should be listed. And then LOV-3 values associated with LOV-2 selection should only be listed.
Can someone offer some insight or point me to an example?
Thanks
Tony

Has anyone been able to implement a series of dependent LOV's in a tabular report which is updateable?
I have a collection which I update 'onchange' if an LOV column is updated to retain the new value. I still have the issue of referencing the 'correct rows' previous LOV value to limit the next LOV's selection list.
Any suggestions on how to reference the previous column's value for the current row?
Desired process flow:
1 .user selects value 2 from LOV 1 [row 1]
-onchange, trigger submit of form back to itself updating the collection.
2. provide LOV 2 [row 1] with limited list of values based on selection in LOV 1 [row 1]
-onchange, trigger submit of form back to itself updating the collection with values of
row 1's LOV 1 and LOV 2
3. provide LOV 3 [row 1] with limited list of values based on selection in row 1's LOV 1 and LOV 2
Is there away to change the dependent list of values using a javascript function? Such as repopulate the LOV?
Help?

NOT urgent. LOV that excludes list item that is already selected

I have a mutiple record block with a LOV item. I want the LOV to display only list items that have not been selected in the other records. The form do not commit after each record, so I cannot use a databse query to exclude the list items that have already been selected.
The only way I could think of is to go through the data block and build a LOV that excludes the list items that are in the records. This seems like a lot of work for a simple task.
Is there an easier way in doing this?
Any help will be appreciated.
- Clayton.

Hello Clayton,
you don't need to commit. You could try to post your records to the database.
But make sure you do a rollback when the user doesn't want to commit.
This will release you from the 'hard work' ;-)

Dropdown List (LOV) Help

I have a request to put a seperate line within the dropdown list to seperate different category data. Is this possible ? Can someone give advise on how to implement it?

I have a request to put a seperate line within the dropdown list to seperate different category data.Your requirement is not clear. Are you talking about seperating data in your LOV by category? For example, say you have an LOV that displays a listing of CARs available for sale:
MAKE        MODEL       COLOR
Ford        Focus       Blue
Ford        Focus       Green
Chevy       Volt        Red
Chevy       Volt        Blue
Dodge       300         Black
Dodge       300         Blue
BMW         M3          White
Mercedes    450SL       Blackand you want:
MAKE        MODEL       COLOR
Ford        Focus       Blue
Ford        Focus       Green
Chevy       Volt        Red
Chevy       Volt        Blue
Dodge       300         Black
Dodge       300         Blue
BMW         M3          White
Mercedes    450SL       Black
______________________________If this is what you want - no you can't do this with a standard Oracle Forms LOV. You could try modifying your query in SQL Developer to add the lines to the output and try this query as the Record Group source of your LOV, but there are no guaruntees this will work.
Please describe your requirement better!

Validate from list behavior ? help needed

Hi,
I have an item whith a lov attached to and the proerty of the lov is validate from list = yes.
But when a create a record and type the begining of the words eg Jean then when i do key-list-val or F9 the lov returns me all the rows and.
And when i press enter in the field then the lov shows with Jean% and show me only the names beginning with Jean.
Why does it only happen when i press enter and not when doing F9?
Should it not be the same behavior ?
Thanks in advance.
PS: it is quite urgent !
Jean-Yves

Hi ,
When you enters a wrong value into a "Validate from List" Item and hit <ENTER> then validation to make sure that the entered value exists within the List and if it is not there , then the forms engine filters the Shows values as the value entered into the Item as helping you to select from the List cause you have entered ambigious Choise and in case no matched entries it display all the list , but in case you display the LOV normally this means you are trying to select a value then no Pre Serach happened unless you specify (Filter Before Display = true) on the LOV properties ,
Best Regards,

Problem of POP LOV in a SQL Report with pagination

I am using a pop up lov (along with some other fields), HTMLDB_ITEM.POPUP_FROM_LOV(5, null, 'EMPLOYEE_LIST', '20', '50')), in a sql report. This is a report with pagination. Whenever I select any value from pop up lov on first page of the report it gets populated properly in the corresponding text field. But from second page onwards it doesnt populate any value.
For example, my report fetches a total of 50 rows, of which I am displaying 15 at a time. The popup lov comes with a text field for each row. Whenever I do select from popup lov for 1-15 rows which come on page 1, the values come up in the text field properly, but for rows 16-30 on second page, 31-45 on third 46-50 on fourth the values do not get populated. When I changed the pagination settings to display 40 rows..the values were still coming properly on page 1(1-40 rows) and not on the next page. Any clues how to resolve this problem?

good find. this is a bug that has already been identified and will be corrected in the upcoming patch release for htmldb. a good work-around for now is to use the equivalent declarative options in the tool. so rather than coding your query like...
select ename , HTMLDB_ITEM.POPUP_FROM_LOV(2, null, 'DEPARTMENT', '20', '50') as "department" from emp
...just code it like this...
select ename , null as "department" from emp
...and then use the column attributes screen for your "department" column to indicate that you'd like that col to be rendered as a "Popup LOV (named LOV)" using your DEPARTMENT list of values.
hope this helps,

Interactive Report - Column list of values

The column header list of values feature is great but I think it would benefit from some usability enhancements. Specifically,
1. Say I have a column which has 100s of distinct values. Clearly, I wouldn't want to enable the drop-down list of values (LOV) when I click on the column header. So I choose None for Column Filter List of Values. Yet, when I click on the column header, I get a [text field|http://screencast.com/t/M1SPYdAT] for filtering the (non-existent) values, which is a little misleading.
May I suggest that choosing None should make this text field not appear? As a workaround, I use a user-defined LOV value like select 'Use <img src="/i/ws/action_dropdown.gif"/> to filter' from dual to nudge the user to use the main report menu.
2. When I use the text field in the column heading LOV to narrow down list, Apex performs a "search as you type" query with a "contains" operator.
May I suggest that
a) this should be configurable (i.e. perform a "starts with" query or "contains" query)
b) the search term matched so far should be highlighted in the results
c) when I click on the column header, the text field should automatically get cursor focus so I can start typing without first having to click in the text field
3. When I do use the main report menu to filter a column, is there a way to disable certain operators from the [Operator dropdown list|http://screencast.com/t/3kUwiNEH] ?
For example, I have an indexed column so certain "index-friendly" operators (equality, starting with, less than, greater than, etc) are fine but I would want to disable operators which would not use the index (contains, not like, etc).
4. I have a User Defined List of Values query for a column and the query returns 80 rows. When I click on the column header, only 11 values are displayed in the dropdown. But when I use Filter from the main IR menu and select that column and click on the LOV, all 80 values are shown. The same query is used in both places so I am puzzled as to why they would return different results.
Is there a limitation on the column header LOV, some varchar2(4000) thing maybe?
Thanks

Vikas,
Thank you for the feedback. For issue #1, we are aware of the bug. We should not display the text field if no LOV defined. Hopefully we have the fix by next APEX release. Issue #3 is a great suggestion. We will take a look to enhance that. I am unable to reproduce #4, could you please provide the test case in apex.oracle.com?
Thank you,
Christina
