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,

Select list based on LOV - and allowing new values

Hi All,
I have a page that has a select list based on a dynamic list of values. I wanted to test out how the system was working, so I truncated all of my tables, and now my select list is blank (which makes sense). The problem is that I can't type anything into the select list. How can I make it so that if there isn't a value returned from the query that populates the LOV, I can just type one in? This also goes further in that if the value I wanted isn't already in the db, how does the user add in another value?
Thanks in advance,
Corey

Hello,
Well as you now know HTML based select lists don't work like that, that widget is called a combo box and there will be built in combo boxes in APEX 3.0, it's a fairly complex dhtml widget.
What you might want to do is provide a text item next to your select box and an Add New Value Option in your select list.

Populate a select list based on sql query

I need to populate a select list using an sql query based on the value value I get from the previous page sent using link . How can I achieve this behaviour ? I tried giving select app_item_id a,app_item_id b from app_item_definition where app_id = :P11_APP_TDL_ID order by 1 in LOV, but it doesn't work . Please advice .

Select list and subquery: "LOV query is invalid"

Hi all,
I want to create a select list with the following format:
"name1 (count of another table)"
"name2 (count of another table)"
I've boiled it down to a simple query with a non-correlated subquery that works fine in SQL*Plus but not as an LOV:
select table1.field1 || (select count(*) from table2) d,
table1.field2 r
from table1
I get this (Apex 3.2.1):
1 error has occurred
* LOV query is invalid, a display and a return value are needed, the column names need to be different. If your query contains an in-line query, the first FROM clause in the SQL statement must not belong to the in-line query.
Even this doesn't work:
select table1.field1 || (select 'a' from dual) d,
table1.field2 r
from table1
I've tried it with an inline view, joining table1 to a select from table2 that returns the count, but I get the same result. Any ideas?
Edited by: MalcA on Jan 22, 2010 12:14 PM

I don't know, but the difference is that the count(*) code goes from the select clause to the from clause.
Other times I had the same problem and always did it and it was the solution.

Problem writing a sql query for a select list based on a static LOV

Hi,
I have the following table...
VALIDATIONS
ID          Number     (PK)
APP_ID          Number
REQUESTED     Date
APPROVED     Date
VALID_TIL     Date
DEPT_ID          Number     (FK)
I have a search form with the following field item variables...
P11_DEPT_ID (select list based on dynamic LOV from depts table)
P11_VALID (select list based on static Yes/No LOV)
A report on the columns of the Validations table is shown based on the values in the search form. So far, my sql query for the report is...
SELECT v.APP_ID,
v.REQUESTED,
v.APPROVED,
v.VALID_TIL,
d.DEPT
FROM DEPTS d, VALIDATIONS v
WHERE d.DEPT_ID = v.DEPT_ID(+)
AND (d.DEPT_ID = :P11_DEPT_ID OR :P11_DEPT_ID = -1)
This query works so far. My problem is that I don't know how to do a search based on the P11_VALID item - if 'yes' is selected, then the VALID_TIL date is still valid. If 'no' is selected then the VALID_TIL date has passed.
Can anyone help me to extend my query to include this situation?
Thanks.

Hello !
Let's have a look at my example:create table test
id        number
,valid_til date
insert into test values( 1, sysdate-3 );
insert into test values( 2, sysdate-2 );
insert into test values( 3, sysdate-1 );
insert into test values( 4, sysdate );
insert into test values( 5, sysdate+1 );
insert into test values( 6, sysdate+2 );
commit;
select * from test;
def til=yes
select *
from test
where decode(sign(trunc(valid_til)-trunc(sysdate)),1,1,0,1,-1)
       =decode('&til','yes',1,-1);
def til=no
select *
from test
where decode(sign(trunc(valid_til)-trunc(sysdate)),1,1,0,1,-1)
       =decode('&til','yes',1,-1);
drop table test; It's working fine, I've tested it.
The above changes to my first idea I did because of time portion of the DATE datatype in Oracle and therefore the wrong result for today.
For understandings:
1.) TRUNC removes the time part of DATE
2.) The difference of to date-values is the number of days between.
3.) SIGN is the mathematical function and gives -1,0 or +1 according to an negative, zero or positiv argument.
4.) DECODE is like an IF.
Inspect your LOV for the returning values. According to my example they shoul be 'yes' and 'no'. If your values are different, you may have to modify the DECODE.
Good luck,
Heinz

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.

Order in a Select List based in a LOV is wrong

I have a select list based upon a LOV SQL Query.
Values in table are:
FIELD
001
002
003
AAA
when I make query in SQL Workshop:
select FIELD from TABLE order by FIELD;
I get
001
002
003
AAA
But when I make a similar query in LOV the result is in the select list
AAA
001
002
003
Someone knows what is happening?
Thank
Ander

It looks like your application is running a different sort / NLS preference then is the SQL workshop. Is there a chance your application identifies a language that sorts differently then default APEX. I am just guessing but it could explain this behavior.OK, I think something like this is happening because my Oracle instance have SPANISH like a NLS_LANG parameter, but why is different result between sql Workshop and LOV query, I have installed english and spanish languages in my apex instance, I get the same problem in both cases.
Other curious think is that my min and max values are OK,
for example
BETWEEN: <select list 1> AND <select list 2>
default value for <select list 1> is
DECLARE
exitvalue varchar2(10);
BEGIN
select min(FIELD) into exitvalue
from TABLE
return (exitvalue);
END;
I get 001
default value for <select list 2> is
DECLARE
exitvalue varchar2(10);
BEGIN
select max(FIELD) into exitvalue
from TABLE
return (exitvalue);
END;
I get AAA
But select list are ordered like
AAA
001
002
003
I have based select list in a lot of different sql ways
select FIELD from TABLE ORDER BY FIELD
select FIELD from TABLE ORDER BY 1
select FIELD from TABLE ORDER BY FIELD ASC
select FIELD from TABLE ORDER BY 1 ASC
Other extraneous think is that I use DESC order I get
003
002
001
AAA
Thanks

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

Select List based on in-line query

Hello everyone, im having a problem creating a select list with the following query:
select result.A d, result.B r
from dual,
(select RMF.nome A, RMF.chapa B
from
medfa_marco_has_colaborador MC,
medfa_projeto_has_colaborador MP,
rm_funcionario RMF
where
MC.mar_id = :P3_SELECT_MARCO and
MC.pro_col_id = MP.pro_col_id and
MP.chapa = RM.chapa) result
but i keep getting the
"LOV query is invalid, a display and a return value are needed, the column names need to be different. If your query contains an in-line query, the first FROM clause in the SQL statement must not belong to the in-line query."
Thnx in advance.
E.R

Okay, first off - does this work in SQL Workshop?
Have you got a semi-colon at the end of the query (you shouldn't have)?
Also when posting code put {noformat}{noformat} before and after your code to preserve formatting and spacing.
Cheers

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.
Tiina

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

Creating a dynamic Selection List based on a View Object

Hello,
I'm new to JDeveloper and I would like to create a JSP Page with dynamic Selection List based on a runtime query or based on a view object (BC4J). The selection made by an user should serve another dynamic query with the necessary parameters that I built using createViewObjectFromQueryStmt(). By now I tried this using the InputSelectLOV from the Component Palette in JDeveloper. But without success. By the way: the selection list is not very large (5 values), so it's not necessary to have a form finding the desired value.
Maybe someone had experience about creating this already. Please give me a tip or a little example.
Thanks.

Designing LOV Query Problem

Hello APEX people,
I posted my problem here:
Designing LOV Query Problem
What I have is a sequence like this:
CREATE SEQUENCE
DR_SEQ_FIRST_SCHEDULE_GROUP
MINVALUE 1 MAXVALUE 7 INCREMENT BY 1 START WITH 1
CACHE 6 ORDER CYCLE ;
What I need would be a SQL query returning all possible values oft my sequence like:
1
2
3
4
5
6
7
I want to use it as a source for a LOV...
The reason why I use the cycling sequence is: My app uses it to cycle scheduling priorities every month to groups identified by this number (1-7).
In the Admin Form, I want to restrict the assignment in a user friendly way - a LOV.
Thanks
Johann

Here ist the solution (posted by michales in the PL/SQL forum):
SQL> CREATE SEQUENCE
dr_seq_first_schedule_group
MINVALUE 1 MAXVALUE 7 INCREMENT BY 1 START WITH 1
CACHE 6 ORDER CYCLE
Sequence created.
SQL> SELECT LEVEL sn
FROM DUAL
CONNECT BY LEVEL <= (SELECT max_value
FROM user_sequences
WHERE sequence_name = 'DR_SEQ_FIRST_SCHEDULE_GROUP')
SN
1
2
3
4
5
6
7
7 rows selected.

Dynamic Select List based on TextField data

Hi,
I like to dynamically display the select list based on the value in the textfield, the data in the textfield is of character type.
Thanks

Hello,
Well as you now know HTML based select lists don't work like that, that widget is called a combo box and there will be built in combo boxes in APEX 3.0, it's a fairly complex dhtml widget.
What you might want to do is provide a text item next to your select box and an Add New Value Option in your select list.

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!
Paul

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!
Paul

LOV Select List How to create query with begin & End in LOV

Dear All,
i am using Apex 3.2 ver
i want to use below code in LOV select list
BEGIN
IF UPPER(:P23_SERVICE_TYPE) like 'GUIDE%' THEN
SELECT NAME D, CODE R FROM SPECIAL_SERV_MAS
WHERE NVL(ACTIVE_FLG,'N') = 'Y'
AND NVL(GUIDE_FLAG,'N') = 'Y'
and CITY_CODE LIKE NVL (:P23_CITY_CODE, '%')
ORDER BY 2
ELSIF
UPPER(:P23_SERVICE_TYPE) LIKE 'ACCOM%' THEN
SELECT   NAME D, CODE R
    FROM   HOTEL_MAS
   WHERE   NVL (ACTIVE_FLG, 'N') = 'Y'
           AND CITY_CODE LIKE NVL(:P23_CITY_CODE,'%')

The requested URL /pls/apex/f was not found on this server.
Oracle-Application-Server-10g/10.1.2.0.2 Oracle-HTTP-Server Server at tidevserv1 Port 7777
How to Resolve it.

Hi Vedant,
you dont need to use begin ...end block
Try the Below code
IF UPPER(:P23_SERVICE_TYPE) like 'GUIDE%' THEN
RETURN
'SELECT NAME D, CODE R FROM SPECIAL_SERV_MAS
WHERE NVL(ACTIVE_FLG,''N'') = ''Y''
AND NVL(GUIDE_FLAG,''N'') = ''Y''
and CITY_CODE LIKE NVL (:P23_CITY_CODE, ''%'')
ORDER BY 2' ;
ELSIF UPPER(:P23_SERVICE_TYPE) LIKE 'ACCOM%' THEN
RETURN
'SELECT   NAME D, CODE R
    FROM   HOTEL_MAS
   WHERE   NVL (ACTIVE_FLG, ''N'') = ''Y''
           AND CITY_CODE LIKE NVL(:P23_CITY_CODE,''%'')
ORDER BY   PRIORITY' ;
END IF;In this way you can create conditional LOVs ,
Hope this will helps you.
