Creating Named lov for each row..........

How to create Named LOV for each row in a field.
i have a tabular in a page. In that tabular i have three fields service_code,*service_name* and No_units.
i have to create lov for service_code for all rows.
how to do this?
plz help...

Hi Frank,
This is the method i wrote in the managed Bean. It works when I hard code the department value to some value(like 10).
public List<SelectItem> getEmployeeList() {
int Deptid = 10;
ArrayList<SelectItem> employees = new ArrayList<SelectItem>();
employees.add(new SelectItem("0", "--Select Employee---"));
try {
Connection con = getConnection();
PreparedStatement ps =
con.prepareStatement("select name from employees where department_id = ?");
ps.setInt(1, Deptid);
ResultSet rs = ps.executeQuery();
while (rs.next()) {
employees.add(new SelectItem(rs.getString("name")));
rs.close();
ps.close();
con.close();
} catch (Exception ex) {
System.out.println(ex.getMessage());
return employees;
How can I pass the row Department Id to this method in the f:selectItems?
I really appreciate your help in resolving this issue.
Thanks

Select item on a Tabular form with a different dynamic LOV on each row

I would like to use a tabular form where one of the columns is a dynamic LOV based Select, and where that dynamic LOV refers to one of the column values on each row.
So if the tabular form represented a list of teams and the LOV-based Select column was the current team leader, I would want that select list to be populated only with the members of that team (different for each row). Since the list of team members is in some other table (all_players or something) I would want to populate the LOV with a query with a where clause that selected only those players records with a team-membership equal to the current tabular form's team id. So, on each row that select list's contents would be different.

I'm beating a dead horse here but I did get something to work with "less" code. My current needs do not require me to cascade drop downs, I only want 1. You can use the query like the in the first reply (but I don't have a table with joins) I created a simple two column table dept_emp with 4 records 10,null 20,null .... I want to fill the nulls with an employee but ONLY an employee that matches the dept. (Same concept of team leader and members).
Here's the query:
select apex_item.display_and_save(1,dept) dept,
apex_item.select_list_from_query(2, name, 'select ename from emp where deptno='||dept) name
from dept_emp
I removed the code that was there already (ApplyMRU) and just put in this code:
BEGIN
FOR i IN 1..HTMLDB_APPLICATION.G_F01.COUNT LOOP
UPDATE dept_emp
SET
name=HTMLDB_APPLICATION.G_F02(i)
WHERE dept=to_number(HTMLDB_APPLICATION.G_F01(i));
END LOOP;
END;
The G_F01 matches the column 1 and so forth. There's more documentation but little explanation at:
http://download.oracle.com/docs/cd/B25329_01/doc/appdev.102/b25309/api.htm#sthref2171
The thing I could not get to work was a dynamic message
#MRU_COUNT# row(s) updated, #MRI_COUNT# row(s) inserted.
Not sure when the MRU_COUNT gets populated (probably in the routine I removed ;))
You're probably way past me by now but I like to have as little code as possible when it comes to maintaining an app. That's why I liked oracle forms so much. This kind of stuff was pretty easy to do.
Thanks again everybody!

Update button in sql report for each row can only get the report value

I have to added Update for each row of records like:
select a.*,'Update' button from (
select c.*,d.login from country c,champ d
where c.champ_id=d.champ_id(+)
order by c.name) a
then go to the report->edit button ->Column Link
I added some items P40_REGION, P40_CHAMPID,P40_ACTIVE,P40_CODE and assign the value like #region#,#active# ,#code# to these item, but when I click the update button in the report I found the values such as #region#,#active# ,#code# is the report value not the select list selected value(the region, active column are displayed as select list lov).
Can anyone tell me how to sort this knid of problem?
Thanks a lot!

Sorry, it doesn't work. I also tried apex_application.g_f01(i), but not everytime I can get the value or get the incorrect value. If you have time you can try to create it like what I have described. Our team use two days now but still can not sort this problem.

How to process a block for each row in an internal table....

Hi experts....
In po approval workflow the scenario is like this.... for each po there may be more than one approver. approvers list i am maintaining in the ztable. list of approvers(no of approvers) is decided by the po value. I have collected these approvers into internal table. now i have to process a block ( approving or rejecting the po... )in the workflow for each row in the internal table.
how can i do this. based on the decision of the 1st approver approves the po then it should go to next approver in the internal table...otherwise end the workflow.....
Please help me......

i have created an internal table in the workflow container in which i am getting the list of approvers....
how can i loop the internal table in the workflow...?
how can i know the index of the loop in the workflow.....(will sy-index work here....? so that i can use loop until step in the main workflow to call the subworkflow..so that if sy-index is greater than no of entires in the itab then i can come out of the loop)

For each row of a table call a pl/sql function

Hi,
i have a search form in adf like this:
parameter1:___
parameter2:____
buttonSearch
Table with results
field1 field2 field3
row1 ------ --------- -------
row2 ------ --------- -------
row3 ------ --------- -------
The user inputs the parameters 1 and 2 then press buttonSearch and the query execute and returns rows 1 to 3.
What i need is for each row call pl/sql function and passed the parameter 1 and 2 and field 1 to 3 (plsql function recives 5 parameters (parameter1, parameter2, field1 , field2 and field3) )
my buttonSearch call a java class that execute ExecuteWithParamters method.
I create the call to my plsql function on Application module class and then export as a java interface.
So i have the function to use in the viewcontroller layer, but i don't know where to use it, and how to pass the paramters: the parameter 1 and 2 that user inputs and the row fields.....
any ideas....
thanks!!

Hi,
for this you need to call the PLSQL function upon table rendering, which means that you need a field in the table referencing a managed bean. In the managed bean you can use #{row} and resolve it using a ValueExpression. #{row} gives you access to the current rendered row (this is why you need to do it when the table renders) and thus allows you to call getAttribute(name) to get the values of field 1 - 3. The search field value you should get through the bindings reference (assuming the search form uses ADF). Then you create an operation binding for the executeWithParameters and call operationBindingName.getParamsMap().put(argname, argvalue); on it.
Frank
Ps.: I am concerned about the performance you get and wonder if it isn't possible to create a transient attribute that executes the function and displays the results. As I understand, the search parameters are only to filter the result set, which you still can do

Using a LoV in each row of a report (SELECT)

Hi everyone,
I have a report of a table in APEX and I'd like to show a column with a Select list that I have saved (LoV). I mean, for each row of the table it must appear this dinamic select list. In addition, I want a button next to every Select list, every row.
I know how to show a static select list using HTML in my SELECT query. I do something like:
SELECT atribute1, atribute2, .... , '<html> select code </html>' as "list"
FROM table1
But I need to use an existing LoV. And then, if the user change one value of one select list, and presses the button in the same row, this value should be processed and do an UPDATE of this row in the DataBase.
I suppose it is possible to do this in APEX, but I still didn't fins the way to do this.
Can you help me, please? If my english is too bad, I can try to explain it better.

It's not necessary any answer.
I was wrong about inserting LoVs with HTML. It is not that hard, it's more simple and I know how to do this now.

SQL merge and after insert or update on ... for each row fires too often?

Hello,
there is a base table, which has a companion history table
- lets say USER_DATA & USER_DATA_HIST.
For each update on USER_DATA there has to be recorded the old condition of the USER_DATA record into the USER_DATA_HIST (insert new record)
- to have the history of changes to USER_DATA.
The first approach was to do the insert for the row trigger:
trigger user_data_tr_aiu after insert or update on user_data for each rowBut the performance was bad, because for a bulk update to USER_DATA, there have been individual inserts per records.
So i tried a trick:
Instead of doing the real insert into USER_DATA_HIST, i collect the USER_DATA_HIST data into a pl/sql collection first.
And later i do a bulk insert for the collection in the USER_DATA_HIST table with stmt trigger:
trigger user_data_tr_ra after insert or update on user_dataBut sometimes i recognize, that the list of entries saved in the pl/sql collection are more than my USER_DATA records being updated.
(BTW, for the update i use SQL merge, because it's driven by another table.)
As there is a uniq tracking_id in USER_DATA record, i could identify, that there are duplicates.
If i sort for the tracking_id and remove duplicate i get exactly the #no of records updated by the SQL merge.
So how comes, that there are duplicates?
I can try to make a sample 'sqlplus' program, but it will take some time.
But maybe somebody knows already about some issues here(?!)
- many thanks!
best regards,
Frank

Adding a check box control for each row of data in a DataModel

Hi all,
I need to add a checkbox control for each row of data on a DataModel object.
I have a "commandButton" at the bottom of DataModel, and whenever someone checks some of the rows on that list of rows,
I need to get the selected dataModel(fragment of the list) in my backing bean.
How do I achieve this functionality in JSF?
Thanks,
Meghasyam.

Thanks,
Meghasyam.You'll want to have a wrapper class as suggested above, which has a "selected" boolean in it. Then use the "binding" attribute of the h:selectBooleanCheckbox component to bind the checkbox to that property... Make the property public and specify the properties exact name in the binding... bindings do not append "get" to the EL.
Here is an example of what your table might look like... This code would display the list of names with a checkbox to the left of each name... When the check box is selected, the "selected" property of that wrapper class is set to true or false as needed. Then when the form is submitted, and you are inside your actionListener or action method call, you can look through your collection of wrapper classes asking each one if it was selected or not... Then do whatever you want with them... In this example, replace "myBackingBean" with the name of your backing bean, and "names" with the name of the method in your backing bean which returns the collection of wrapper classes... create a flag "public boolean selected" or similar in your wrapper class..
<h:dataTable id="namestable"
value="#{myBackingBean.names}"
var="aName">
<h:column>
<h:selectBooleanCheckbox binding="#{aName.selected}"/>
<h:outputText value="#{aName.nameText}"/>
</h:column>
</h:dataTable>
Let me know if that isn't clear enough and I'll see if I can find a better way to explain it...

Updating A Table in a for each row trigger

I have a trigger,
create or replace trigger ins_ibpm_temp_trig
after update of ethic_dt on ethics_approval_info for each row
My issue is that I need to update the ethics_approval_info for each record based on the ethics date that was updated. I am getting the error
ORA-04091: table ORACLETEST.ETHICS_APPROVAL_INFO is mutating, trigger/function may not see it.
So the issue here of course is that I am trying to update a table, that is already in the middle of updating. Is there any way to get around this?

Different LOV for different rows

Hi,
Imagine a tabular report with a number of rows, and a select list for each row populated based on data in that row.
I've seen a solution for this in a few threads, but I've tried to replicate it in 4.2.1.00.08 with no success
Select list filter in a tabular form problem
Tabular form - Different LOV for different rows
my query includes this as a column
APEX_UTIL.SAVEKEY_NUM(duration) durationwith another column defined as "Select List (query based on LOV)" using
select apex_util.keyval_num d, apex_util.keyval_num r from dualand while the duration varies, the LOV is always stagnant.
This occurs in both classic & updateable reports (tabular forms).
I was skeptical that it would work anyway, since I'm sure the query is resolved/bound before rendering each LOV - but that's just assuming background process logic.
Is the only alternative solutions to use APEX_ITEM.SELECT_LIST_FROM_QUERY() ?
Scott

Ahh, I had only tried that on my classic report example. It only seems to have that effect on the tabular form.
Makes me hesitant to use it with that kind of behaviour.
When comparing normal tabular form, one set to generic, and another changed back - I saw no differences in the metadata that I would think have some form of impact on rendering behaviour
APEX_APPLICATION_PAGE_RPT
APEX_APPLICATION_PAGE_REGIONS -- customization/timeout_cache_after changed, component_signature had trailing 0
APEX_APPLICATION_PAGE_RPT_COLS -- lost tabular form attributes, region had lost selector column, in fact I'm having trouble bringing it back to a point where it actually saves data.

Update primary key with a tabular form based on a select list for each row

Hello!
I've two tables: Table1 with only one column (primary key) is a foreign key for table2.column1 (primary key). There is also a second primary key column in table2.
Now I want to change the primary key values in table2.column1 with a tabular form (MRU) based on a select list (LOV based on table1.column1) for each row.
The user should be able to choose for every row a new value from the select list to change the old primary key value at this position.
How can I do this with ApEx?
I've the tabular form and so on, but at the moment I get the following error:
"Error in mru internal routine: ORA-20001: Fehler in MRU: row= 1, ORA-20001: ORA-20001: Die aktuelle Version der Daten in der Datenbank wurde geändert, seit der Benutzer einen Update-Prozess eingeleitet hat. ..."

"Error in mru internal routine: ORA-20001: Fehler in MRU: row= 1, ORA-20001: ORA-20001: Die aktuelle Version der Daten in der Datenbank wurde geändert, seit der Benutzer einen Update-Prozess eingeleitet hat. ..."
Thank you for your support!

:new., lob columns and after insert ... for each row trigger

I'm having this little problem with
my update/insert triggers and lob columns.
I have this little trigger:
CREATE OR REPLACE TRIGGER BLOB_DATA_INSERT
AFTER INSERT ON BLOB_DATA
FOR EACH ROW
BEGIN
INSERT INTO BLOB_DATA_CHANGE VALUES(CHANGE_SEQ.NEXTVAL, 'I', :NEW.ID,:NEW.DATA);
END;
Which works except when the DATA column
is a BLOB or CLOB (There is no data in :NEW.DATA. I even tried some of the DBMS_LOB package procedures)
The one thing that is different for the lob columns is that the application updating
the data is using a bind statement with returning, like:
INSERT INTO BLOB_DATA
VALUES(:ID,EMPTY_BLOB())
RETURNING DATA INTO :DATA;
COMMIT;
Thanks for any help

Aperture 3.1.2 When exporting files to Finder is creating a folder for each file, that means export 200 files is creating 200 folders for each files. Does anyone knows how to fix this. Thanks

No. This is NOT true. I've been battling with this for a couple hours.
I choose Export>Versions
choose
Subfolder Format: Project Name
no custom subfolder
Name Format: Current Version Name.
Aperture creates project folders for each image and names them Projects1, Projects2, Projects3 etc.
To be sure, I have no project named Projects
x
This particular Aperture library has 16 projects. you can see in the screen grab it's created more than 30 folders
If I uncheck the Subfolder, that is say NONE, I just get images and images and images, not in their project folders (of course, because I've said NONE, so why would it put them in project folders?)
I just want to export the entire library and have the versions placed in folders named by the projects from which they came.... ez enough, no?

Check Box for each row in report -- all rows deleting when pressing DELETE

Hello experts! I have set up a report with a check box for each row. When I click the DELETE button to delete the selected rows, every single one of the rows get deleted...even the ones that are not selected. I have my process point set to "On Submit - After computations and validations".
This is my delete process (SHG is the table and SHG_ID is the primary key):
FOR i in 1..HTMLDB_APPLICATION.G_F01.count
LOOP
DELETE FROM SHG
WHERE SHG_ID = HTMLDB_APPLICATION.G_F01(i);
END LOOP;
Also, I've added to query in the region source this line:
htmldb_item.checkbox(1, SHG_ID) del,
Where does the "1" come into this? Not sure what I am doing wrong!

The 1 (first argument to all the htmldb_item.* APIs) corresponds to the array number in htmldb_application.g_fNN. So 1 will populate array g_f01, 2 will populate g_f02 and so on.
Your code seems fine, it should delete only the checked rows. Are you sure there is no other process on the page that might be deleting the rows? See if you can put up an example on htmldb.oracle.com
