HTMLDB 2.0 bug - tabular forms - select list from named LOV

Hi!
Changing a column in a tabular form to 'select list (named lov)' gets the following error in HTMLDB 2.0 when you try to add a row (to an empty table in my case):
PL/SQL error at column 133.
Create a table and then create a tabular form on it. Then change a report column to be a 'select list (named lov)'. Save and run the form and the error occurs.
Thanks!
Dave Venus

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.

OnChanger="get_ajax_select_xml(this);" with select list (query named LOV)

Hello,
i used Vikas'example Re: cascading lov for tabular form
i have a problem with Select list (query based LOV)
when run tabular form i have the following error:
report error:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
the number of rows of the Lov are 900
the display variable is 70 char
is there any limit?
Thank in advance

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

I got so frustrated I started over. I'm following the how to create a manual form.

The problem I'm now having is even though I display items as hidden, there is a column holder on the report for them. If I go into the report attributes and toggle the show attribute off I cannot reference an items value in my logic. I used /&nbsp/ for the column heading but I still get the little sort arrow where the column heading should be. I tried to toggle the sort attribute off but the sort arrow still shows up. How can I use the apex_item.hidden and not get a place holder for the column on a report? Thanks, Elizabeth

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.

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...

Problems with customizing select lists and popup LOVs

Hi
I have 2 problems about select lists and popup LOVs.
The first one is about a select list in a tabular form.
It should be created with APEX_ITEM.SELECT_LIST_FROM_LOV or similar and take its values from a named LOV.
This worked fine but now it should also have the possibility to enter a free value.
I tried to accomplish that by creating a APEX_ITEM.POPUP_FROM_LOV, but there is a problem with the function that is called by the arrow icon right to the input field (for eg. genList_f11_5()).
If the row is added by addRow, then it works fine, but if the row is is not empty
then the function call is like genList_f11_$_row() and the input field gets no value, when a LOV option is selected.
The other problem is about a select list which should have the possibility to enter a custom value and
also there should be the possibility to select several values. I tried to implement this by a text area containing the selected values and a multiple select list, with an event handler in each option. The user could click options and they would be copied to the text area. The problem is that I couldn't make the event handler work in IE.
I would appreciate any ideas about either of these problems.

Hi,
If you download application you can see source.
I have not write any instructions, sorry.
If you are on Apex 4 you can just load jQuery UI autocomplete library and take ideas from my app.
If you download my sample in zip there is uncompressed htmldbQuery library.
You can see that and take only function htmldbAutocomplete.
Then check jQuery UI document
http://jqueryui.com/demos/autocomplete/#method-search
There is method search that you can use open list just by click of input.
I hope this helps at start.

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.

Dynamically changing the select list in an LOV based on the login user

We have a field in a form which is a combobox.The form is to be linked to different profiles of users.Based on the logged in user we would like to restrict the select list in the LOV.ie user1 should see a LOV which is different from that seen by user2.Is this possible.If so how can this be done?Kindly reply.
Thanks & Regds,
Jayanthi

Thanks for ur reply.But my problem is that i have a table having details of some products which includes spareparts also(Name,id,price etc).In my form i have the combobox field which should have a list of these products which the user can select.Now depending on the user's profile he should see only his related products(One profile of users should view only the products but not the spares while the other should view only spares.)The details of both the products and spares are in the same table.we have a criteria to differentiate between the products and the spares.The LOV should display at run time, either products or spares depending on his profile as he logs in. Hope u understood my problem.
Regds,
Jayanthi
Hello Jayanthi,
I had a similar situation in my last project.
While you can solve this by modifying your query, this will always come around as may be later some other criteria to restrict based on User/His Role/Something else. Hence I fixed it at design level itself. Though I can't give my situation I can tell you the solution applying my logic.
Altering your Product Table and adding one more database Column say Product_Category and updating the table with Product Category =1 for Products and 2 for Spares. You can extend this further for other types.
Create a new Table say User_Groups that will have
Group_id
Group_Name
User_Id columns and will contain all the User ids inserted groupwise.
Create one last Table Group_Product_Map
That will have
Group_id
Category_id
This will store each Group_Id followed by Category_id of Products to which these group members will have access to.
Now write a database function getCategory( p_User) which will query User_Groups table to get Group_Id
and further query Group_Product_Map Table based on group_id to get Category_Id.
This function will return category_id.
Huh!
So your LOV will have a query as select *(or whatever) from Product where category_id = getCategory(portal30.wwctx_api.get_user)
Hope this helps

Populate Select List from Checkboxes?

How do I populate a Select List from a checkbox set's checked display values and submitted values?
I'm guessing I need to parse the colon-delimited values, but I have no idea how to get the display values, or how to put all of that into the Select List.
Any ideas?
Cheers,
Ben

Hello,
Every select list item can be based on LOV. You can read more about it in here - http://download-uk.oracle.com/docs/cd/B31036_01/doc/appdev.22/b28550/bldapp.htm#CHDFGFHI
If you are trying to populate a select list, using JavaScript, you can see a good example in here - http://htmldb.oracle.com/pls/otn/f?p=11933:37
Hope this helps,

Select list from query in report

Hello everybody,
I want to include a select list from a query in a report's colomn, but the select list should only be displayed conditionally. I wanted to do this with the help of "case when" in the corresponding SQL statement.
The select list itsself works, but when I combine it with "case when" I always get the error message:
ORA-01427: single-row subquery returns more than one row
The select statement is as following:
select
htmldb_item.checkbox(1,rownum) " ",

x.stunden_ilp,
x.stunden_ild,

Found 2 ways to solve it:
*1. dynamic action (JQuery)*
$("#f20_1234 option[value=13]").attr('selected', 'selected');
*2. process*

--HTP.p('problem()');
HTP.p('html_SetSelectValue(''f20_903'',188)');
HTP.p('html_SetSelectValue(''f20_903'',189)');

Select List (based on LOV) query problem

Hello experts! I have a small problem here, which I can't seem to overcome.
I have a page item (select list based on LOV), which is based on a query. The query returns all potential employees of a department that are responsible for a certain duty. So far so good!
The problem is that there are two departments, which should not only see there own employees but also the name of the employee that has carried out a certain task. However, due to my query, the name of that person is not displayed - only the pk is returned.
Do you have a recommendation how I display all employees of a specific department and have additional values translated as well?
My query is as follows: select str_bearbeiter, cnt_bearbeiter from vt_tbl_bearbeiter where cnt_bearbeiter in (SELECT
CNT_REGIERUNGSBEZIRK FROM TBL_REGIERUNGSBEZIRK) union select str_bearbeiter, cnt_bearbeiter from vt_tbl_bearbeiter where int_behoerde in (SELECT
CNT_REGIERUNGSBEZIRK FROM TBL_REGIERUNGSBEZIRK where STR_REGIERUNGSBEZIRK = lower (:app_user)) whereas :app_user holds the information of the department.
Any hint is appreciated!
Many thanks,
Seb

Okay, I just had the right idea and it's working well! Sorry for posting!
I return the name of the employee that has edited a dataset and simply add all others of the logged on department! Really easy! Should have thought of that before posting! ;-(
The correct code is select str_bearbeiter, cnt_bearbeiter from vt_tbl_bearbeiter a, vt_tbl_punktdaten b where a.cnt_bearbeiter = b.int_bearbeiter and
inv_pt_id_sub = :P4_PTIDS
union select str_bearbeiter, cnt_bearbeiter from vt_tbl_bearbeiter where int_behoerde in (SELECT
CNT_REGIERUNGSBEZIRK FROM TBL_REGIERUNGSBEZIRK where STR_REGIERUNGSBEZIRK = lower (:app_user))Bye,
