Select List Query Restriction

Hello,
Hopefully this is a quick one.
I'm trying to restrict the results of a query in a report by using a select list with a named dynamic LOV. Basically the report will only display rows that are the same as the value currently in the select list. My problem is that I'm trying to have an 'All' value in the select list that will result in all rows being displayed.
I have tried using a LIKE in the query and setting the LOV to display null, then setting the null return value to %%%. This works exactly how i want it to if I hard code it into the query. However, when I try to use it as a value in the select list no rows are returned. The variable in the URL looks fine however it's not translating properly.
Has anyone got any suggestions or alternate ways of doing the same thing?
Cheers.

Yes that has fixed the problem, either way % or %%% wasn't working.
However adding the ||'%' to the end of the select list variable in the query appears to have fixed the problem. I don't understand why though, it should have worked with the null return value of %...
Thanks a lot.

Select List (query based LOV) in a wizard created report form

I have created an updatable report form with 3 columns:
app_id
user_id
group_id
Each app_id has multiple group_id's associated with it, and I want to show the group_id field as a Select List (query based LOV) that contains the groups associated with the app_id.
My query for the select list needs to be similar to the following:
SELECT DISPLAY_NAME, GROUP_ID
FROM APPLICATION_GROUPS
WHERE APP_ID = ?????
ORDER BY 1
The problem is, I don't know how to reference the app_id from the main report to replace the ?????.
In other words, if my report returns 2 rows of data like this:
app_id----------user_id----------group_id
1-----------------24------------------3
2-----------------24------------------15
Then how do I get the group_id column to be a select list of possible groups for each application? If app_id 1 has 3 groups associated with it, 3, 4, & 5 and app_id 2 has 2 groups associated with it, 15 & 16, then those each of the select lists should be based on the app_id.
Hopefully I explained this clearly.
Thanks,
Kris

Leo,
Thanks for the response, but I don't think you quite understand my problem. If I go to the Column Attributes screen for the group_id field, I have the "Display As" drop down set to "Select List (query based LOV)", not "Select List (named LOV)". This requires that the sql query be written in the "List of values definition" text area below. Within that text area I have the following query:
SELECT DISPLAY_NAME, GROUP_ID
FROM APPLICATION_GROUPS
WHERE APP_ID = ?????
ORDER BY 1
The APP_ID that I need to reference is for the current row of data that is being processed. Therefore, I can't use a :PNNN_APP_ID variable, because that field does not exist on the page.
Hopefully this explains it a little better.
Thanks,
Kris

Character string buffer too small (select list query based LOV)

Hi,
Using the select list query based LOV with a select witch is too big, you get this error.
report error:
ORA-20001: Error fetching column value: ORA-06502: PL/SQL: numeric or value error: character string buffer too small
When using the Popup LOV query based LOV) then it works nice.
Can that be solved somehow?
With the Popup LOV the return value is displayed in stead of the description.

Hi Andy,
How do I incorporate your suggestion on a report ?
Example : I have
select apex_item.display_and_save(1,column1,5) col1,
apex_item.display_and_save(2,column2,5) col2 ,
apex_item.popup_from_query(3, emp_name, 'select user_name, name empname from table2) col3
Table 2 is a long list , and I'm getting string buffer too small due to this.
Your suggestion with HTP is good but I'm not sure how to implement it for reports as I'll like the user to change the values with the select_list.
I'm not using forms as they want mulit-record on the same page.
Hope to hear back from you soon.
Thanks very much.

Tabular form (select list Query based LOV)

Hi all,
I have this situation:
a tabular form with two "select list (query based LOV)" fields.
The first one must affect elements in the second one. And so the second query based LOV field should has a "where attr1 = first_list_selected_value" in the query.
Is this possible ? Could you show me some advices ?
thanks in advance.

OK, thank you.
But maybe I wasn't too clear.
I need cascading LOV for each row of my tabular form.
I have a EMP tabular form
select
"ROWID",
"EMPNO",
"ENAME",
"JOB",
"MGR",
"HIREDATE",
"SAL",
"COMM",
"DEPTNO"
from "#OWNER#"."EMP" I need a Select List for DEPTNO for each record of table. After set a value, the second "Select List" for ENAME should be affected automatically.

Select List (query based LOV) in V. 4.1.1.00.23

Hi guys,
I am having some problems with an APEX application that I have exported from V. 4.1.0.00.32 and imported on V. 4.1.1.00.23.
I have a Tabular Form region where I have a column which is Display As "Select List (Query based LOV)".
If I add a new row - choose a new value (not the same as any of the above rows) and "Apply Changes"/"Submit" the value in the new row changes to the value of the 1. row of the tabular form :-( I can update this new row and then it saves the right value... It looks like it is only when inserting a new row.
Is this a bug or is it a feature ;-)
Hope you can help...

Cascading select list (query based) in a tabular form

Hi,
In my application i have two select list in a tabular form one for selecting manager_id and other for selecting employees for the selected manager_id how can i do it in apex 4.0
thanks in advance

Ok i will assume that you have 2 select list items called (P1_MANAGER AND P1_EMPLOYEE)
In employee select list u need to find Cascading LOV Parent Item(s) and set it to P1_MANAGER. Ofc your sql query must be smth like this:
SELECT employee_name d, employee_id r FROM employee_table WHERE employee_manager = :P1_MANAGER

Is is possible to avoid hard-coding the Item in a shared Select List Query?

I created a "Select List" in the Shared Components area as follows:
My goal is to create a shared select list that can be used on any form for a particular Field.
IF :P10_FK_RSTA_CODE is NULL THEN
RETURN
          'select col_description, col_code_pk
          from CODE_TABLE
          where col_active_ind = ''Y''';
ELSE
RETURN
          'select col_description, col_code_pk
          from CODE_TABLE
          where col_code_pk = :P10_FK_RSTA_CODE';
END IF
Which works great, but how can I make the select list work for the same column on a different form?
Because :P10_FK_RSTA_CODE is hard-coded in the function, I can't reuse this Function from a different form.
(I could rename the Field on every form to the same name, but I'm hoping there is a better way.)
Is there a way I can pass in a variable from the Field Item to make this dynamic where I can use it on any form?
Also, I am very new at this, so if there is a better way to do this, I would greatly appreciate any input.
Thanks in advance.

Welcome to the forum: please read the FAQ and forum sticky threads (if you haven't done so already), and update your profile with a real handle instead of "956902".
When you have a problem you'll get a faster, more effective response by including as much relevant information as possible upfront. This should include:
<li>Full APEX version
<li>Full DB/version/edition/host OS
<li>Web server architecture (EPG, OHS or APEX listener/host OS)
<li>Browser(s) and version(s) used
<li>Theme
<li>Template(s)
<li>Region/item type(s) (making particular distinction as to whether a "report" is a standard report, an interactive report, or in fact an "updateable report" (i.e. a tabular form)
With APEX we're also fortunate to have a great resource in apex.oracle.com where we can reproduce and share problems. Reproducing things there is the best way to troubleshoot most issues, especially those relating to layout and visual formatting. If you expect a detailed answer then it's appropriate for you to take on a significant part of the effort by getting as far as possible with an example of the problem on apex.oracle.com before asking for assistance with specific issues, which we can then see at first hand.

Unable to create a dynamic action ALERT to be generated on a Select List when particular value is selected.

Hi everyone, this should be so easy, yet I am stuck.
I have a form region with an item P110_VESSEL_ID. This item is a select list. It is based on the query:
select distinct v.vessel_name, v.vessel_id
from vessels vessels v, frequent_fishermen ff
where ff.dea_permit_id = :G_PERMIT_ID and
ff:vessel_id = v.vessel_id
UNION
select v.vessel_name, v.vessel_id
from apex_collections a, vessels v
where collection_name = 'SUPVES_COLLECTION' and
a.c002 = v.vessel_id
If the user decides against the values in the select list query, they may opt to SELECT ALL VALUES. This SELECT ALL VALUES is a POST ELEMENT TEXT on P110_VESSEL_ID.
<a id="popVessels" href="#"><font color=blue>Select from ALL Vessels</a>
This all works fine.
The issue is that when the user selects a vessel name = 'UNKNOWN' and it's corresponding vessel_id value, I would like an ALERT to appear indicating that they should double check that the vessel is UNKNOWN and not that the is no vessel.
I created a dynamic action
event= change
select type = item
item = P110_VESSEL_ID
True ACtion #1 is the ALERT.
I currently have no other logic, but cannot even get this to work. Any thoughts. I have also tried the SELECT TYPE = jQuery Selector = select[name='P110_VESSEL_ID'] but that does not work either (though I am not certain if the value should be P110_VESSEL_ID or the static name of VESSEL_ID).
Any help is appreciated.
ps. the page is not submitted when the vessel is changed. There is other data that needs to be entered both in this region and others and many validations run when submit, so the submit would not be an option.
thanks again,
Karen

This should work. Sometimes I've see where there is other javascript on the page that may have some errors and is causing the dynamic action code to not be executed. Use your favorite browser script console to try and determine if this may be the case.

P.S. Your jQuery selector can be: select#P110_VESSEL_ID

Using a Select list with Submit

I am trying to use the select list with Submit on my page.
I have 3 select lists.
On the first one,I am showing the list of all jacks.
When the user selects a jack from the first list, I want to show all the jacks except the one which was selected.
When the user selects a jack from the second list, I want to show all the jacks except the ones selected in the first list and the second list.
I have created the select lists with submit and then I have put the query for getting the jacks. I created an unconditional branch. I am also passing the variables so that I can set the values of the items on submit.
I also created a computation as mentioned in one of the OTN discussions, and have mentioned the value of second list to be calculated from the first and 3rd from first and second.
But after clicking the first select list, I am losing all the existing values on the first page. I wonder what I am missing here. Can anyone hellp?
Thanks,
Gargi

Gargi,
In this case using 'select list with redirect' makes more sense rather than with SUBMIT. So change all the select lists to 'select list with redirect' (it redirects to same page inserting 'select list' value session state).
Now for the 2nd select list query add a condition in where clause like
WHERE sl_col != :P1_SL1And for the 3rd select list query add a condition in where clause like
WHERE sl_col NOT IN (:P1_SL1, :P1_SL2)Hope it helps :-)
Cheers,
Hari

Select lists and deactivated values

Consider the following simplified test case.
1. create tables like this
create table lov_values
lov_pk number primary key
, name varchar2(10)
, active varchar2(1) not null
insert into lov_values valeus ( 1, 'A', 'Y' );
insert into lov_values valeus ( 2, 'B', 'Y' );
insert into lov_values valeus ( 3, 'C', 'Y' );
commit;
create table trx
trx_pk number not null primary key
, lov_fk number not null foreign key references lov_values
) ;2. Create an APEX Insert/Update form on the trx table. Define the LOV_FK item as a select list with this query
List of values definition:
select name d, lov_pk r
from   lov_values
where active = 'Y' ;
Display Extra Values: Yes3. Users use the APEX form to create records like this:
trx( trx_pk, lov_fk ) = ( 10, 1 )   -- users sees LOV_FK value as "A"
trx( trx_pk, lov_fk ) = ( 20, 2 )   -- users sees LOV_FK value as "B"
trx( trx_pk, lov_fk ) = ( 30, 3 )   -- users sees LOV_FK value as "C"4. A year later an admin deactivates lov_value 2/B by setting active to 'N'.
5. When a user queries trx row 10 they still see "A".
6. When a user queries trx row 20 they now see "2".
7. When a user queries trx row 30 they still see "C".
In step 6 I'd like the user to see "B" whenever they query old data with that value but I never want them to be able to create new trx rows with 2/B or update the LOV_FK value of existing rows to be 2/B. I'd also like to avoid using a pick list with a popup window just for selecting from a list of two (could be a few) values.
Just wondering how others have dealt with this scenario in their APEX apps.

I actually just found a simpler way in Select list filter in a tabular form problem forum thread. In the query that defines the tabular form I added a column called HIDDEN_FK_VALUE as follows.
select
"TRX_PK",
"TRX_PK" TRX_PK_DISPLAY,
"LOV_FK",
APEX_UTIL.SAVEKEY_NUM("LOV_FK") hidden_fk_value
from "#OWNER#"."TRX"Then I modified the the Select List query to look like this.
SELECT name d, lov_pk r
FROM lov_values
WHERE (active = 'Y' OR lov_pk = APEX_UTIL.KEYVAL_NUM )Works like a charm. Thanks everyone for your input.

APEX 4.01 Tabular form with select list error

When i create a tabular form and i add a select list(query based LOV) the form is not displayed but gives me the next error
report error:
ORA-20001: Error fetching column value: ORA-06502: PL/SQL: numeric or value error: character string buffer too small
somebody have an idea what is happening here
is this still a bug in APEX 4.01?
hope to have an answer soon.

Hi Jari,
It returns about 1100 records which i think is not much.
But even when i narrow the amount of records the problem is not solved.
it this a bug?

How to Fix Select list with redirect Problem

Hi
I have a field F1 of type select list with redirect.
It has an LOV with 2 values USA and Canada for eg..
I choose USA and hit save and saved it to DB..
now f1 is stored in table with my User ID and value is USA.
when I log in next into this page,
this field should show me the value USA.
But its not happeneing for me..it always gives the null value when i re login
is there a way to default/source it to my value??
I am using
select f1 from table
where user_id=:user_id;
i checked and this query works in sql plus...

Earl, please see the response in italics for each of your questions below:
You do want your default value to be one of the values in the select list. Otherwise why would you want the value there at all?
So, then should I have a default value at all? And, if yes, then what should it be?
And can't you just set the default value to the first value in your select list, whatever that is, so the first value is the selected value?
I did that and it works, only if the first value in the select list is always going to be there. The select list is based on a column data in a table. And if the data for that column changes then the values in the select list will change. And, the first value might not always be the same.
I guess I'm not clear why this isn't doing what you want, besides the fact that
you seemed to have removed the default value from the dynamic select list query, which you shouldn't do.
I removed the first value (it could have been any values) from the select list to mimic the "dynamic" select list -- just to test. The select list data is based on a table and the data in the table can change.
Thanks

Autofill cascading select lists

Hello,
Can anyone please help me out with implementing an autofill cascading select lists. If anyone has implemented a sample example ; can you please provide me the link.
thanks,
orton

Which version of Apex you r using?
If its 3.2 you can refer to this link: http://htmldb.oracle.com/pls/otn/f?p=31517:119:2521957760329919:::RP,::
if its 4.0 then enter the name of parent item in "Cascading LOV Parent Item(s)" property of the select list
and use the parent Item name in the where clause of select list query, like this.
Select name d, eid r from emp where emp_id in(select emp_id from dept_emp where dept_id = :p01_1);
where employee select list is the child and the department is the parent select list.
Thanks

Select list with Title Tag

Hi,
I have a form where one of the field is a Select list ( query based LOV )
STATIC2:Test 1;1,Test 2;2,Test 3;3
The list that is returned on my page look like this in HTML
<select ... >
<option value=""></option>
<option value="1" >Test 1</option>
<option value="2" >Test 2</option>
<option value="3" >Test 3</option>
</select>
I would like ApEx to add a title field on the list so the returned value on the page would be like
<select ... >
<option value=""></option>
<option title="Help 1" value="1" >Test 1</option>
<option title="Help 2" value="2" >Test 2</option>
<option title="Help 3" value="3" >Test 3</option>
</select>
I have tried many ways to achieve this but it seems apex does not give us the possibility to add attributes directly to the option of the list.
The "Element Attribute" field is only for the whole select list,
Is there a way to do this ?
Thanks in advance
Sebastien

i managed to find a workaround
STATIC2:Test 1;1,Test 2;2,Test 3;3
every option build it this way
<option value="1" >Test 1</option>
so changing the value of the LOV like this
STATIC2:Test 1;1 || '" title="Help 1'
will make my option in html print like
<option value="1" title="Help 1" >Test 1</option>
It's far from nice but it's doing what i needed :)
