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,
Radovan

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

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 stop SQL Server Agent Job if Stored Procedure returns value 0

I have SQL Server 2012 SSIS.
I have 2 SSIS packages.
I have created SQL Server Agent Job for running packages.
I have created steps. If first step have run succesfully next step is run.
I have need to add new logic.
I have validation stored procedure, which validate DB table values and returns 1 or 0.
I would like to create logic where first of all this SP is runned. Return value of SP determines if steps are run or not.
I was thinking to use Execute SQL Task for running SP.
If value 1 is returned, then run rest of Tasks is run.
If value 0 is returned, what should I do so that Job is stopped? I need assistance!
I want current step to stop never moved to next step.
Is there any SSIS tasks, which can stop the Job?
Or should I make Step for running validation SP?
How to do so that if value 0 is returned stop Job.
Kenny_I

Please refer the below link:
http://technet.microsoft.com/en-us/library/aa260308(v=sql.80).aspx
Please read Remarks carefully!!!
Remarks
If a job is currently executing a step of type CmdExec, the process being run (for example, MyProgram.exe) is forced to end prematurely. Premature ending can result in unpredictable behavior such as files in use by the process being held open. Consequently,
sp_stop_job should be used only in extreme circumstances if the job contains steps of type CmdExec.
Permissions
Execute permissions default to the public role in the
msdb database. A user who can execute this procedure and is a member of the
sysadmin fixed role can stop any job. A user who is not a member of the
sysadmin role can use sp_stop_job to stop only the jobs he/she owns.
When sp_stop_job is invoked by a user who is a member of the
sysadmin fixed server role, sp_stop_job will be executed under the security context in which the SQL Server service is running. When the user is not a member of the
sysadmin group, sp_stop_job will impersonate the SQL Server Agent proxy account, which is specified using
xp_sqlagent_proxy_account. If the proxy account is not available,
sp_stop_job will fail. This is only true for Microsoft® Windows® NT 4.0 and Windows 2000. On Windows 9.x, there is no impersonation and
sp_stop_job is always executed under the security context of the Windows 9.x user who started SQL Server.

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 do I get data to the from in a form based on a stored procedure

I would like to create a form based on a stored procedure. I have bound LOV's that lookup the ID of the data that is to be displayed on the form. Then I have a button that reads the database and populates the fields on the form. This is our current UI standard on our portal site, and I need to copy that UI exactly in order to mix HTML DB code with our current portal code because we can not afford to re-write all our code in portal to HTML DB. Can this be done, and how can it be done? Thanks

We are developing an entire HR system for our organization using portal forms. I am trying to prototype in HTML DB to see if we can switch our future development to this new product. However, we already have 50 or so forms that follow a certain user interface look and feel in portal. I am trying to create this interface look and feel in HTML DB. What we are doing in Portal is have a lookup section at the top of each form where you find the record you want to update with LOV's, sometimes 2 or 3 bound together, and then have a lookup button that does PL/SQL to read the database and populate the fields on the form. Then there is an Update button at the end of the form that takes the fields off the form and passes them to a stored procedure. I can not figure out how to do the Lookup button type of code to read information and bring it to the form when doing a form based on a stored procedure.

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

Link to Create directory
http://www.adp-gmbh.ch/ora/sql/create_directory.html
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 dynamic context based on a structure defined in the program?

Hi Experts,
         I need to create a dynamic context based on a structure wa_struc which i have define programatically.
When I pass wa_struc to structure_name parameter of create_nodeinfo_from_struc, i get a runtime error:
"Parameter STRUCTURE_NAME contains an invalid value wa_struc."
How to create dynamic context based on a structure defined in the program?
I have written the code like this:
TYPES: BEGIN OF t_type,
            v_carrid TYPE sflight-carrid,
            v_connid TYPE sflight-connid,
         END OF t_type.
Data: i_struc type table of t_type,
         wa_struc type t_type.
data: dyn_node   type ref to if_wd_context_node.
data: rootnode_info   type ref to if_wd_context_node_info.
rootnode_info = wd_context->get_node_info( ).
clear i_struc. refresh i_struc.
select carrid connid into corresponding fields of table i_struc from sflight where carrid = 'AA'.
cl_wd_dynamic_tool=>create_nodeinfo_from_struct(
parent_info = rootnode_info
node_name = 'dynflight'
structure_name = 'wa_struc'
is_multiple = abap_true ).
dyn_node = wd_context->get_child_node( name = 'dynflight' ).
dyn_node->bind_table( i_struc ).
Thanks
Gopal

Hi Michelle,
          First of all Special thanks for your informative answers to my other forum questions. I really appreciate your help.
Coming back to this question I am still waiting for an answer. Please help. Note that my structure is not in a dictionary.
I am trying to create a new node. That is
CONTEXT
- DYNFLIGHT
CARRID
CONNID
As you see above I am trying to create 'DYNFLIGHT' along with the 2 attributes which are inside this node. The structure of the node that is, no.of attributes may vary based on some condition. Thats why I am trying to create a node dynamically.
Also I cannot define the structure in the ABAP dictionary because it changes based on condition
I have updated my code like the following and I am getting error:
TYPES: BEGIN OF t_type,
CARRID TYPE sflight-carrid,
CONNID TYPE sflight-connid,
END OF t_type.
Data: i_struc type table of t_type,
dyn_node type ref to if_wd_context_node,
rootnode_info type ref to if_wd_context_node_info,
i_node_att type wdr_context_attr_info_map,
wa_node_att type line of wdr_context_attr_info_map.
wa_node_att-name = 'CARRID'.
wa_node_att-TYPE_NAME = 'SFLIGHT-CARRID'.
insert wa_node_att into table i_node_att.
wa_node_att-name = 'CONNID'.
wa_node_att-TYPE_NAME = 'SFLIGHT-CONNID'.
insert wa_node_att into table i_node_att.
clear i_struc. refresh i_struc.
select carrid connid into corresponding fields of table i_struc from sflight where carrid = 'AA'.
rootnode_info = wd_context->get_node_info( ).
rootnode_info->add_new_child_node( name = 'DYNFLIGHT'
attributes = i_node_att
is_multiple = abap_true ).
dyn_node = wd_context->get_child_node( 'DYNFLIGHT' ).
dyn_node->bind_table( i_struc ).
l_ref_interfacecontroller->set_data( dyn_node ).
But now I am getting the following error :
The following error text was processed in the system PET : Line types of an internal table and a work area not compatible.
The error occurred on the application server FMSAP995_PET_02 and in the work process 0 .
The termination type was: RABAX_STATE
