How to create an LOV based on a dynamic query

Hi,
Can someone tell me how to query a dynamic query for LOV. On my base page I have a dropdown-box (that will show the table names for searching) and is dynamically populated based on users access e.g. if user A logs in he may see 5 values (these values are basically table names) in a drop down if user B logs in he may see 10 values. I also have two input fields one field a user can enter value and the other field is read only and a torch icon for LOV so the user can search and select values that are populated in the input fields on the base page.
How can I have my LOV that takes in a value selected in the dropdown and anyvalue entered in one of the input fields and search in the table selected in the dropdown box.
Basically my LOV should do a search on the table and some search value passed when clicking on the torch icon. So a user can select any table-name in the drop down and my LOV should do a search only on the selected table. Once on the LOV Popup want to have a search field there but it only searched on the table selected in the dropdown on the based page. And the selected value on the LOV Popup page gets populated in fields on the base page.
Any help is appreciated.
Thanks

Hi,

How to create a LOV based on a stored procedure returning a cursor

Hello,
I've tried to search the forum, but did not find much. We are facing a problem of large LOVs and creating large TMP files on the app server. Our whole application is drived by store procedures. LOVs are built manually by fetching data from cursors returned from stored procedures. That creates the issue when whole LOV needs to be stored in the memory and thus the TMP files.
Is there anyway how to create LOV based on a procedure returning cursor ?
Thank you,
Radovan

Hello,
As of now we populate the record group by looping through the ref cursor and adding rows into it. Is there a better way? That forces the whole record group to be stored in a memory on the app server.
Thank you,

How to create a Form based on a dynamic table?

Hello,
The Select statement below creates a table based on a string (string is a value of an item):
select * from table (pkg_util.fn_get_table (:P18_VALUE))I need to create a region on a page with a Form based on this table.
I was able to create a Report, but not a Form.
I need to create a Form, which would return updated string to the page item.
How can I solve this please?

Hello Gentlemen,
I have created a Tabular Form, based on APEX_ITEM API, as you suggested, here is the code below:

END;Can you please see what's wrong with the code?
Also, I tried to set a temp. item with the value, to see if the process returns something, like that:
DECLARE

BEGIN
FOR i IN 1..APEX_APPLICATION.G_f*30*.COUNT

END LOOP;
     :p18_temp := lc_string;
END;and it did not work.
Also, it is the second Tabular Form on this page. The first one is created using wizard, and it works perfect, with the same update process:
DECLARE
lc_string VARCHAR2(4000);
BEGIN
FOR i IN 1..APEX_APPLICATION.G_f*01*.COUNT

      lc_string := lc_string|| '[' ||APEX_APPLICATION.G_f*03*(i) || '|' || APEX_APPLICATION.G_f*04*(i) || ']';
END LOOP;
--Database processing using the concatenated string here
END;Also, both forms are opening in a modal pop-up dialog window.
I use a Dialog Region plug-in for that.
May be this is causing a problem?
But still, the first form works fine!?

How to create dependent LOV based on procedure?

Hi,
There are two dependent list of values which i need to create. There is an existing package which returns the list.
Can you suggest which approach should i use to create these list. Should i execute the procedure in the IMPL class and then bind the list to the transient VO or should i create a table which stores the result of the package and then use query based VO.
After selecting the list values and clicking on GO it should generate a table too based on that list values selected.
Which approach is correct? If any other approach then please mention.
And can you explain how do we bind the list to the transient VO for the first approach if thats the correct approach.
Thanks in advance

Hi,
I would build programmatic view objects for both of them (I usually also prefer having the View Objects based on a custom entity object). The tricky part is that you need to override the default View Criteria behavior (as you have to detect the view criteria, its condition and then map it to the stored procedure call)
Here are some links that will help:

How to create an lov based on another lov?

For example, the first lov is a list of regions like east, west....

Hi
This is not possible in Discoverer 4i. The concept of Cacading lists of values was only introduced in Discoverer 10g R2 (10.1.2).
Now there's a good reason to upgrade :-)

How to create a formula based condition in bex query designer

hi all,
i have scenario in query designer where i need to calculate Key performance indexes based on characters and key figures iam using.for example the condition is like:
"if call received is less than call projection then give call received else null"
how and where to define the condition and i need to name the condition to display it seperatly.please help me in this issue.
regards
Vamshi D Krishna

hi you have to break down your conditions and then code for them.
for e.ge.
if actual == 0
vart = 0.
else if actual-target ==0
          vart = 0.001
       else
         vart = actual -target
       endif
endif
now we start with first condition use operators from boolean catagory
(Actual != 0)*(other amount)
this solves first if condition... if actual = 0 value actual != 0 will be zero we got our desired value.
if other case then we have give else condition.
(Actual != 0)*(((actual - target) == 0 )*0.001+((actual-target)!=0)*(actual-target))
in the second half we have coded the else part.
in the same way you can proceed for your logic

Lov based on a dynamic view object

Build JDEVADF_11.1.2.0.0_GENERIC_110531.1615.6017
Hi,
I have a database table containing a column with the Name of a Table as content.
I created a dynamic view and overwrite this with a method in Appmodule.
Then I add to the element in the main view the Lov. I execute the method in JSP page.
But the SelectOnechoice list is empty!
Where is the problem? How can I create a Lov based on a dynamic view object?
Thanks in advance and best regards
Edited by: NewBB on 12.08.2011 00:53

Hi Neliel,
thank you for your reply.
My problem is not the same. I can also see my dynamic view objects as selectonechoice. I have a table T1 has a column t1c1 (Number),
another table T2 (dynamic view object) with two columns t2c1 (Number) and t2c2 (varchar2).
In my application I want to represent the values of t1c1 as selectonechoice with the values of t2c2.
and that does not work. My list is empty. Any idea???

How to create a condition based on a select that retrieve dynamically a LOV

Hi all, I need to create a condition based on a select that retrieve dynamically a LOV.
So, the condition have to be:
inventory_item_id NOT IN (SELECT inventory_item_id FROM apps.mtl_system_items_kfv WHERE concatenated_segments = 'GENERAL_FAULTS_IPTV')
I need to create a LOV based on this select without making any join with the folder which contains the field inventory_item_id, because otherwise I have the contradiction:
and o124757.INVENTORY_ITEM_ID = o118741.INVENTORY_ITEM_ID -- join between the main custom folder (o118741) and the LOV custom folder (o124757)
and o118741.INVENTORY_ITEM_ID NOT IN (o124757.INVENTORY_ITEM_ID) -- condition
These two condition together don't show any data, obviously....This means also, that I can't use a calculated field, because if I want to see this field, I have to create a join, another time, with the main custom folder.
I tried to create a LOV on the Administrator, but when I create the condition I have to check manually the values....and if in the future this LOV will increase I need every time to re-check all the values.....instead I need that the inventory_item_id have to be NOT IN dinamically in the list of values retrieved by the select.
Anybody has inplemented something similar ??
Thanks in advance
Alex

Hi alex,
SELECT incidents.INVENTORY_ITEM_ID,
pcodes.PROBLEM_NAME
FROM apps.cs_incidents_all_b incidents,apps.jtf_rs_problem_codes_v pcodes
WHERE incidents.category_id IN (SELECT category_id
FROM mtl_categories_kfv
WHERE concatenated_segments = 'IPTV')
AND incidents.PROBLEM_CODE = pcodes.PROBLEM_CODE
where incidents.INVENTORY_ITEM_ID NOT IN SELECT inventory_item_id
FROM apps.mtl_system_items_kfv
WHERE concatenated_segments = 'GENERAL_FAULTS_IPTV'
You want to add this condition to the first query it holds good for this scenerio.All the items which are NOT IN will be retrieved.Here you are selecting other than "General_faults_iptv"
But again your trying to select in the second query where you want "General_faults_iptv"
SELECT inventory_item_id
FROM apps.mtl_system_items_kfv
WHERE concatenated_segments = 'GENERAL_FAULTS_IPTV'
If you carefully go through what your doing,you will understand.In the above explantion ,there will be no records generated.First query your saying NOT IN and again your saying for the same IN,how will records retrieve its meaningless.
I dont know what you want to get from second query.I would suggest you to do is dont use the second query and just use the first query and you will get.Here is the query and this will give you result.
SELECT incidents.INVENTORY_ITEM_ID,
pcodes.PROBLEM_NAME
FROM apps.cs_incidents_all_b incidents,apps.jtf_rs_problem_codes_v pcodes
WHERE incidents.category_id IN (SELECT category_id
FROM mtl_categories_kfv
WHERE concatenated_segments = 'IPTV')
AND incidents.PROBLEM_CODE = pcodes.PROBLEM_CODE
AND incidents.INVENTORY_ITEM_ID NOT IN SELECT inventory_item_id
FROM apps.mtl_system_items_kfv
WHERE concatenated_segments = 'GENERAL_FAULTS_IPTV'

HOW TO CREATE A DFF BASED ON ORGANIZATION

Hi,
I want to create a DFF which would have 5 different context values, i want 2 of them to be available in one organization and other 3 in other organization, how i can achieve this.
Regards,
Usman.

Hello,
"HOW TO CREATE A DFF BASED ON ORGANIZATION"
1- I will create a customized table having two columns one is for context name and other is for org_id,
2- then i will create a value set on this table and will use this on 'Value Set' field on 'Descriptive Flexfield Segments' window.
3- In the where clause of this value set i will pass org_id from profile $PROFILES$.ORG_ID,
4- this will restrict the context based on org_id And user will only have context related to there org
I have successfully achieved the above requirment.
Find below the restriction you should follow so that Value set is available in LOVs on "Descriptive Flexfield Segments" window:
Value sets used for context fields must obey certain restrictions or they will not be available to use in the Value Set field in the Context Field region of the Descriptive
Flexfield Segments window:
• Format Type must be Character (Char)
• Numbers Only must not be checked (alphabetic characters are allowed)
• Uppercase Only must not be checked (mixed case is allowed)
• Right-justify and Zero-fill Numbers must not be checked
• Validation Type must be Independent or Table
If the validation type is Independent:
• the value set maximum size must be less than or equal to 30
If the validation type is Table:
• the ID Column must be defined, it must be Char or Varchar2 type, and its size must
be less than or equal to 30. The ID column corresponds to the context field value
code (the internal, non-translated context field value).
• the Value Column must be defined, it must be Char or Varchar2 type, and its size
must be less than or equal to 80. The Value column corresponds to the context field
value name (the displayed context field value).
• the value set maximum size must be less than or equal to 80
All context field values (the code values) you intend to use must exist in the value set. If
you define context field values in the Context Field Values block of the Descriptive
Flexfield Segments window that do not exist in the context field value set, they will be
ignored, even if you have defined context-sensitive segments for them.
Best Regards,
Usman.

How to create a report based on a DataSet programatically

I'm working on a CR 2008 Add-in.
Usage of this add-in is: Let the user choose from a list of predefined datasets, and create a totally empty report with this dataset attached to is. So the user can create a report based on this dataset.
I have a dataset in memory, and want to create a new report in cr2008.
The new report is a blank report (with no connection information).
If I set the ReportDocument.SetDataSource(Dataset dataSet) property, I get the error:
The report has no tables.
So I must programmatically define the table definition in my blank report.
I found the following article: https://boc.sdn.sap.com/node/869, and came up with something like this:
internal class NewReportWorker : Worker
      public NewReportWorker(string reportFileName)
         : base(reportFileName)
public override void Process()
         DatabaseController databaseController = ClientDoc.DatabaseController;
         Table table = new Table();
         string tabelName = "Table140";
         table.Name = tabelName;
         table.Alias = tabelName;
         table.QualifiedName = tabelName;
         table.Description = tabelName;
         var fields = new Fields();
         var dbField = new DBField();
         var fieldName = "ID";
         dbField.Description = fieldName;
         dbField.HeadingText = fieldName;
         dbField.Name = fieldName;
         dbField.Type = CrFieldValueTypeEnum.crFieldValueTypeInt64sField;
         fields.Add(dbField);
         dbField = new DBField();
         fieldName = "IDLEGITIMATIEBEWIJS";
         dbField.Description = fieldName;
         dbField.HeadingText = fieldName;
         dbField.Name = fieldName;
         dbField.Type = CrFieldValueTypeEnum.crFieldValueTypeInt64sField;
         fields.Add(dbField);
         // More code for more tables to add.
         table.DataFields = fields;
         //CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo info =
         //   new CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo();
         //info.Attributes.Add("Databse DLL", "xxx.dll");
         //table.ConnectionInfo = info;
         // Here an error occurs.
         databaseController.AddTable(table, null);
         ReportDoc.SetDataSource( [MyFilledDataSet] );
         //object path = @"d:\logfiles\";
         //ClientDoc.SaveAs("test.rpt", ref path, 0);
The object ClientDoc referes to a ISCDReportClientDocument in a base class:
   internal abstract class Worker
      private ReportDocument _ReportDoc;
      private ISCDReportClientDocument _ClientDoc;
      private string _ReportFileName;
      public Worker(string reportFileName)
         _ReportFileName = reportFileName;
         _ReportDoc = new ReportDocument();
         // Load the report from file path passed by the designer.
         _ReportDoc.Load(reportFileName);
         // Create a RAS Document through In-Proc RAS through the RPTDoc.
         _ClientDoc = _ReportDoc.ReportClientDocument;
      public string ReportFileName
         get
            return _ReportFileName;
      public ReportDocument ReportDoc
         get
            return _ReportDoc;
      public ISCDReportClientDocument ClientDoc
         get
            return _ClientDoc;
But I get an "Unspecified error" on the line databaseController.AddTable(table, null);
What am i doing wrong? Or is there another way to create a new report based on a DataSet in C# code?

Hi,
Have a look at the snippet code below written for version 9 that you might accommodate to CR 2008, it demonstrates how to create a report based on a DataSet programmatically.

How to create a record based on the name of a file in the file-system?

Hi,
With a lot of pictures I want to have a database to gather some information about these pictures.
First question is how to generate a record based on a file in the file system?
e.g. the pictures are "c:\fotos\2009\01\disc_001.jpg" to "c:\foto\2009\01\dis_98.jpg" .
now i want to create records with as one of the attributes the name of the picture (not the picture itself). how to create these records (based on the information of the file-ssytem). i.e. the number of records should be the same as the number of pictures.
any suggestions?
any reaction will be appreciated.
Leo

You can create a list of files in the directory and read the list files from that directory.

How to create a report based on selected item from Select list?

Hi,
I have created a tables_LOV based on:
select table_name d, table_name r from user_tab_cols
where column_name like '%_type%'
Then I created a page item ListOfTables, Display as select list and pointing to tables_LOV.
I run the page, and i can select the table i want from the drop down list.
How to create a report based on the selected item? (ex: select * from selected_table)
many thanks in advance
Salah

Hi Salah,
Allright, have a look at this page: http://apex.oracle.com/pls/apex/f?p=vincentdeelen:collection_report
I think that simulates what you're trying to accomplish. I've set up the simplest method I could think of.
The report is based on an apex collection. If you are not familiar with that, you should study the documentation: APEX_COLLECTION
To recreate my example you should:
1) create an (interactive) report on your collection
SELECT *
   FROM APEX_collections
WHERE collection_name = 'MY_COLLECTION'
2) create a page_item select list for the tables you want to display (in my case this is called "P38_TABLES" )
3) create a dynamic action that triggers on change of your select list page_item. The dynamic action must be a PL/SQL procedure perfoming the following code:
declare
l_query varchar2(4000);
begin
l_query := 'select * from '||:P38_TABLES;
if apex_collection.collection_exists
        ( p_collection_name => 'MY_COLLECTION' )
then
    apex_collection.delete_collection
      ( p_collection_name => 'MY_COLLECTION' );
end if;
apex_collection.create_collection_from_query
    ( p_collection_name => 'MY_COLLECTION'
    , p_query           => l_query
end;
Make sure you add your page_item to the "Page Items to Submit" section.
4) Add an extra true action that does a refresh of the report region.
Here are two pictures describing the da:

Creating a LOV based in a Web Service

Hey guys...
I need to create a Lov based in a Web Service Result, but in always getting the same error:
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.
Queries that I'm trying:
Original Query:
select extractValue(value(t),'/*/imgLocation','xmlns="http://oracle.ovs.api/types/"') "imgLocation"
, extractValue(value(t),'/*/imgName','xmlns="http://oracle.ovs.api/types/"') "imgName"
from wwv_flow_collections c,
table(xmlsequence(extract(xmltype.createxml(c.clob001),'//getAllTemplateResourcesResponseElement/result','xmlns="http://oracle.ovs.api/types/"'))) t
where c.collection_name = 'P1_GETALLTEMPLATERESOURCES2_RESULTS'
Other Query that I tried:
select imgLocation, imgName from (
select extractValue(value(t),'/*/imgLocation','xmlns="http://oracle.ovs.api/types/"') "imgLocation"
, extractValue(value(t),'/*/imgName','xmlns="http://oracle.ovs.api/types/"') "imgName"
from wwv_flow_collections c,
table(xmlsequence(extract(xmltype.createxml(c.clob001),'//getAllTemplateResourcesResponseElement/result','xmlns="http://oracle.ovs.api/types/"'))) t
where c.collection_name = 'P1_GETALLTEMPLATERESOURCES2_RESULTS')
And I tried creating a view, but I dont know where I have to put this.. Maybe in another process?
create view as
select imgLocation, imgName from (
select extractValue(value(t),'/*/imgLocation','xmlns="http://oracle.ovs.api/types/"') "imgLocation"
, extractValue(value(t),'/*/imgName','xmlns="http://oracle.ovs.api/types/"') "imgName"
from wwv_flow_collections c,
table(xmlsequence(extract(xmltype.createxml(c.clob001),'//getAllTemplateResourcesResponseElement/result','xmlns="http://oracle.ovs.api/types/"'))) t
where c.collection_name = 'P1_GETALLTEMPLATERESOURCES2_RESULTS')
Thanks

Fox,
I'd start by adding column aliases D and R to the query and see if that helps.

How to create an ODS based on a particular table

Can Anybody tell me how to create an ODS based on a particular table and what are the basic requirements for that

Hi Priya,
If my understanding is right, you want to create an ODS based on a database table.
Here, I will assume that you already know how to create an ODS. Otherwise, do let me know so that I can guide you on how to do it.
Basically, an ODS consists of two important sections i.e.
1. Key Fields
2. Data Fields
First, we must identify what are the field(s) in the table that make its records unique. You can think of this as database's primary key(s) e.g. Document Number. These field(s) must be inserted in ODS' Key Fields section. You can only insert Characteristics in Key Fields and the InfoObjects in this section will uniquely identify an ODS record or line item.
Next, you can include the rest of the fields (either Characteristics and Key Figures) in ODS' Data Fields and activate the ODS.
Having done that, you have already successfully create an ODS based on a database table.
Hope that helps.
Best wishes,
Syuhair.
