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 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

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...

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.

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!

Select query based LOV for tabular form attributes

Hi HTMLDB Team,
Congrats u all for the new release of HTMLDB in htmldb.oracle.com.
I badly need a solution of the below problem.
Say , i have table called user_col_comments now i want to display the table_name ,column_name and comments in a tabular form.I displayed only one row for the tabular form.Now i create a select query based LOV for attribute table_name where i got all table_name in drop down list.
Point is that after selecting any data from drop down table list i want to get the corresponding fields to be populated in column_name attributes.How can i wrote the select query based LOV for the attibute column_name.
I wrote it as 'select column_name d,column_name r from user_col_comments where table_name=:TABLE_NAME Its not working?
Similarly i want same thing to display for comments after matching both table_name and column_name.
Any solution to get rid of those problem will be highly appreciable...
If u need my htmldb.oracle.com userid and password to solve the problem i will sure let u email it.
Cheers,

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

Chart based on Select list with submit Lov problem

Hi,
I have one page with interactive report showing username with links, date and
database actions.
Another page contains one region having flash chart based on select list with submit Lov.
The lov is created by dynamic query.
Every time when i click the 1st page report link, the 2nd page lov is populating the value automatically. But the problem is chart displays NO DATA FOUND message though the LOV has many values.
I don't want to display any null values so set to NO for LOV
I tried to write Before header computation (PL/SQL Function Body) to set the lov value, but the query is displayed as such.
I don't want to assign any static default value also as the values are dynamic for every link.
The following is my Before header computation of Select list with submit (Item name is p11_schema). (PLSQL Function Body)
begin
if :p11_schema is null then
return 'select distinct owner schema1, owner schema2 from auditing
where access_date=' || :p11_access_date
|| ' and username=' || :p11_username
|| ' order by owner';
end if;
end;
This is my chart query.
select null link, obj_name label, sum(sel_count) "Select", sum(ins_count) "Insert", sum(upd_count) "Update", sum(del_count) "Delete" from auditing
where username=:p11_username
and access_date=:p11_access_date
and owner=NVL(:p11_schema, OWNER)
group by owner, obj_name
Example: If there more than one records in the lov, the graph should display the 1st record. When i select another record, the chart accordingly display the selected values. But inially it should not display "NO DATA FOUND" message.
I tried using all the combinations of computation type for the lov, SQL query ( I could not use if conditon then), PLSQL expression, PLSQL function body. But it does not work out.
Can anyone please help me out.
Thanks.

Hi Scott,
Thanks for your reply.
I found out the solution for this problem as below.
But i did it in different way to tackle the dynamic query wich returns more than one record using rownum always the 1st record when it is empty instead of assigning constant (static) value like '1'. And i am returning LOV itself for both null or not null condition as below.
Declare
q varchar2(4000);
begin
if :p11_schema is null then
q:='select distinct owner schema from auditing';
q:=q || ' where username=:p11_username ';
q:=q || ' and access_date=:p11_access_date ';
q:=q || ' and rownum<2 order by owner';
Execute immediate q into :p11_schema USING :p11_username, :p11_access_date;
end if;
return :P11_SCHEMA;
end;
Thanks.

Problem with query based LOV

Hi,
Maybe someone could help me with the following. I think it is a shortcoming of HTMLDB, but I'm not sure.
I've got a Select List item, P10_PERSON, which resides in a tabular form. The Select List is based on a query, say:
select name   display_value
,      id     return_value
from   personAs is should be, P10_PERSON shows only the names.
When my action is an insert or modification, the results will be writen in the table PERSON_MEETING.
Now I want to make sure that the same person coulden't be selected a second time for the same meeting. So I alter the query based LOV with the following:
select name   display_value
,      id     return_value
from   person
where id not in (select person_id
                  from   person_meeting
                  where meeting_id = :P10_MEETING_ID)This sounds correct and works in Designer, but not in HTMLDB. The NAME isen't shown anymore, instead the ID is shown in the page.
Is this because the person doesen't actually exists anymore in the LOV after it has been saved (stored in PERSON_MEETING)? If so, does anyone knows a work-around?
Thx!

I've got 3 tables. PERSON, MEETING and PERSON_MEETING.
They have the following structure:
# PERSON            #
# ID   NUMBER       #
# NAME VARCHAR2(50) #
# MEETING                   #
# ID          NUMBER        #
# DESCRIPTION VARCHAR2(100) #
# PERSON_MEETING    #
# ID         NUMBER #
# PERSON_ID NUMBER #
# MEETING_ID NUMBER #
#####################In PERSON there are 3 records, in MEETING there is only 1.
PERSON:
ID     NAME
1      KEVIN
2      BILL
3      JOHN
MEETING
ID     DESCRIPTION
1      DEVELOPERS MEETINGNow I want to link the persons to a meeting in the PERSON_MEETING table.
The column MEETING_ID will be filled automatically through a variable or parameter (I don't know the exact term).
I defined the PERSON_ID column as an query based select list with the query:
select name   display_value
,      id     return_value
from   personThis works perfectely, the select list (or lov) shows KEVIN, BILL and JOHN. When I select BILL and save my adjustment, the following record will be shown in PERSON_MEETING
PERSON_MEETING
ID     PERSON_ID     MEETING_ID
1      2             1Now that I inserted BILL as a participant for the Developers meeting he should be removed from the select list. Only KEVIN and JOHN should be in the list. Therefore I change the query of the select list into:
select name   display_value
,      id     return_value
from   person
where id not in (select person_id
                  from   person_meeting
                  where meeting_id = :MEETING_ID):MEETING_ID is the item in the page containing the ID of the meeting.
When I make this adjustment, the select list only contains KEVIN and JOHN (as it should), but the first record shown on the page (record with BILL) doesen't show BILL anymore, instead his ID will be shown (2)...

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.

Jari
