Set label of an item dynamically through pl/sql function

Hi ,
How Can I get the label of an item dynamically through a pl/sql function.
I have a table that stores the label name for these items.
I want to set the label for the item based on the value in my table ?
Is it possible ?
any ideas ?
Thanks in advance,
Dippy

If I understand you correctly, you are using a standard report region, but want to dynamically name the column headers? The only way I've been able to get this to work is to create hidden items for each column header, calculate the value you want for each item, then reference the item in the column header using &item_X. for the column header name.
The problem is that at this point, APEX doesn't allow for dynamic column naming unless you want to do everything yourself using a PL/SQL process that builds the report table manually. I've done that for certain complex reporting tools.
I understand it's tedious to create all the column header items; I have one report that has over 72 items used in this way. It was a pain, but it got the job done.

Creating Region & Items Dynamically based on SQL Result

Hi,
I need to create regions dynamically during runtime based on SQL.
So the number of regions and title will depends on the SQL result.
I came accross the PLSQL Dynamic Content region type. I searched in the internet, I could not find a matching example.
I looked at the APEX book, it mentions about 'Creating a Matrix of Fields Programmatically' but It's not very descriptive and it's using www_flow_api which i couldn't find documentation about it.
So I am turning into this forum for help.
Can you guys guide me to dynamically create region in a page?
for e.g
If my sql returns 5 records, I need to create 5 regions. Each region will contain a dynamically created tabular form as well depending on another SQL (from table function).
Please let me know if I am not being clear about my question.
Thanks a lot in advance.

hello,
I have the following SQL statement in my region.
SELECT APEX_ITEM.DISPLAY_AND_SAVE(1,rectype) rectype,
 APEX_ITEM.DISPLAY_AND_SAVE(2,class_id) class_id,
 APEX_ITEM.DISPLAY_AND_SAVE(3,attribute_id) attribute_id,
 decode(rectype,1,''||title||'',
 2,'<big>'||title||'</big>',
 3,replace(title,chr(13)||chr(10),''),
 apex_item.textarea(4,title,5,200)) title,
 decode(rectype,1,''||review1st||'',
 2,apex_item.text(5,review1st,3,3),
 3,APEX_ITEM.SELECT_LIST_FROM_LOV(5,review1st,'ARTIST_RANK',null,'NO'),
 apex_item.hidden(5,review1st)) review1st,
 decode(rectype,1,''||review2nd||'',
 2,apex_item.text(6,review2nd,3,3),
 3,APEX_ITEM.SELECT_LIST_FROM_LOV(6,review2nd,'ARTIST_RANK',null,'NO'),
 apex_item.hidden(6,review2nd)) review2nd
FROM TABLE (pkg_artist_review.f_artist_review (:P21_ARTIST_SEQ, :P21_ARTIST_DISCIPLINE,:P21_REVIEW_YEAR))as you can see I use DECODE because I need to do HTML formatting on the value and create ITEM according to the value of 'rectype'
decode(rectype,1,''||title||'',
 2,'<big>'||title||'</big>',
 3,replace(title,chr(13)||chr(10),''),
 apex_item.textarea(4,title,5,200)) title, so the report result would look like
rectype title
[display f01] title
[display f01] title
[display f01] title
[display f01] [text area f04]My question is :
I would think my array list f01 and f04 will have different number of values inside.
f01 will have 4 value, whereas f04 will only have 1.
I tried to use
decode(rectype,1,APEX_ITEM.DISPLAY_AND_SAVE(4,''||title||''),
 2,APEX_ITEM.DISPLAY_AND_SAVE(4,'<big>'||title||'</big>'),
 3,APEX_ITEM.DISPLAY_AND_SAVE(4,replace(title,chr(13)||chr(10),'')),
 apex_item.textarea(4,title,5,200)) title, I only ended up having the HTML code written to the report.
How can I handle such situation?
I need my array list to have the same number of records thus i could just use one index to iterate through the value.
Thanks in advance.

Kill user sessions dynamically through PL/SQL

Hello,
Every night I have to DROP one user in order to recreate the entire schema. In order to do this I have to disconnect the user from the DB by killing its sessions. I am using following PL/SQL code
ALTER SYSTEM ENABLE RESTRICTED SESSION;
begin
    for x in (
            select Sid, Serial#, machine, program
            from v\$session
       where username = 'STARSTAGING_DB'
   ) loop
          execute immediate 'Alter System DISCONNECT Session '''|| x.Sid
                  || ',' || x.Serial# || ''' IMMEDIATE';
    end loop;
end;
DROP USER starstaging_db CASCADE;
ALTER SYSTEM DISABLE RESTRICTED SESSION;
I have also tried using keyword KILL instead of DISCONNECT of session.
Most of the day this works, user is dropped and new one is created, but sometimes I get the following problem.
The problem that has occurred in a log file is:
PL/SQL procedure successfully completed.
DROP USER starstaging_db CASCADE
ERROR at line 1:
ORA-01940: cannot drop a user that is currently connected
System altered.
CREATE USER STARSTAGING_DB IDENTIFIED BY *****
ERROR at line 1:
ORA-01920: user name 'STARSTAGING_DB' conflicts with another user or role name
Does anyone have an idea how I can make sure that the user for sure disconnects, so that I can drop him?
Best Regards,
Vladimir

Cannot comment on a better approach as that means a proper analysis of the business requirements. Just keep in mind that killing sessions is a brutal way to manage user connectivity to the database - and should be seen as an exception and the last resort.
You can wrap your schema drop code into a retry loop. Something as follows:
loop
   begin
      ..do the drop..
      success := true;
exception when FAILED then
      dbms_lock.sleep(60); -- sleep 60 seconds
end;
retry := retry + 1;
exit when success or retry > HAVE_WAITED_LONG_ENOUGH;
end loop;

Item data using PL/SQL block region

hello community,
I have searched the whole forum using Pl/SQL but couldn't find an answer for this.
I have a PL/SQL Anonymous block region, containing database items fetched by a process and custom items getting set by the Pl/SQL source.
based on the ID I am getting the records i.e.
Region Source (PL/SQL Anonymous block)
declare
CURSOR cpc_cur is SELECT "PRODUCT", "APPCODE", "COMCODE", "DESCRIPTION" from cp2 where "ID" = :P4_ID;
begin
for cpc_rec in cpc_cur
loop
:P4_P_NAME := cpc_rec.product;
end loop;
end;
The custom item is text field with source Item.
The item value is not filled in for the first time after login, but it shows the value in the session state as with status 'I', but from then onwards it works fine.
Why is the value not fetched the first time?
even I tried the postcalculation using nvl and it sets it to null.
Also set_session state doesn't work.
If I make the custom Item as Pl/SQL function, and write the query then it works fine, but gives problem as while inserting a new record the query has no ID to refer.
Thanks in advance.
Piyush

Thanks Scott!!
1) I am using PL/SQL region to get the data for few items on the form region which is based on a table, all table attributes are database items and additional Items whose data I am fetching from the PL/SQL are Custom items.
2) Yes the loop executes only once per page view, Is their a better query?
3) Well its very dumb to have a item source as item pointing to itself, but since the values are in session with status 'I' I thought this could do the trick!
4) As the item source type used is [only..], the first time user logs in it doesn't displays the value, need to refresh the page, but the second time its gets the values form the session.
5) If I make the Item source as PL/SQL function, I just fetch the records individually, same as in the query which works fine, but the items are also used for insertion (add new) and I clear the cache, so it gives error as it cannot execute the pl/sql function(no ID while addition)
I hope I have answered your questions! If you have patience you can read the detail description.
test application on oracle server
http://apex.oracle.com/pls/otn/f?p=24296:1:3544773135949858:::::
login/password test/test
Application name :Test
The page has 2 regions. when clicking on SN the values are transfered to form, except for 'Appcode'.
Detail Description:
I have a page with 2 regions.
One region is a report region showing fewer details from a view. The other region is a PL/SQL(form region), which shows all the details and is linked to the report region.
While linking I pass the ID from report and autofetch the data in form region.
But some Items are not related to that database, so I created few items on form region (Custom Items). To fill in these values I did these things.
1) Pass them through script (but passing 7 parameters through script is not good)
2) Made another autofetch process to fetch the remaining Items, but it seems that its not possible to have 2 autofetch process on one form region.
3) Changed the form type from HTML to PL/SQL, to assign the custom items values through code.
for cpc_rec in cpc_cur
loop
:P_custom_item := cpc_rec.data;
end loop;
Either make source type static or Item (the same item P_custom_item).
This pl/sql code do assign them the values, In the session state their status is 'I', but are not displayed on the page for the first login, need to refresh the page, as the source used is (only when..) it gets the value the second time.
4) Made the item source as PL/SQL function and assign them the value. It works fine, but the same item is also used displaying description while insertion(gives error while insertion), so made a conditional process, even that gives the same error.
I have a questions.
If an Item status is 'I' in the session state, why is it not displaying the value on page.
Thanking you in anticipation

Set Page item value when paging through an sql query report

I have a report that includes a checkbox to indicate which rows a process is to be run on. I have a "Select All" button that sets a value to check all boxes in the report, and deselect button to turn that feature off. The page only renders one of the buttons at a time depanding on the value. If the "Select All" is turned on, I would like to set the value to "OFF" when a user goes to another page of the report.
For example:
A user enters the page and the report is rendered. The rows returned are greater than what is displayed. The paging options for the report are shown. 1-15 16-30 etc. It is currently showing the first 15 rows of the report.
The user clicks the select all button, and all checkboxes are now checked. Currently it will remain this way until the deselect button is clicked.
When the user clicks the report paging, I would like to set the value of the Select All item to off.
Does anyone know how to do this at this point?

Set up a Foscam wireless webcam through BaseStation 7.71 inside and outside of my home network.

I bought a X10 wireless Security Camera last year and it took me months to figure out how to set it up to access the video both inside my home and through my iPhone remotely, even on my Mac at my office. I thought I would provide my process of getting this done to help those trying something similar. Yes the X10 camera works as a Foscam Camera. I am very happy with the result. The biggest challenge was Port Forwarding the Apple Basestation but now that I figured it out, it is easy.
"How I set up a Foscam wireless webcam through Apple Hardware and software to work inside and outside of my home network seemlessly."
What you need:
-Foscam or compatible camera, (iPad or iPhone or Mac or better all three)!
-Service Provider Router.
-Apple Base Station, Extreme or Express. 7.71
-'ip scanner' (software for Mac, app for iPad/iPhone.
-CCTV Camera pros port scanner app for iPhone.
First REMOTE ACCESS
Go to www.dyndns.org and set up an account. For about $20/yr you can have 30 host websites. Write down the user name and password as you will need it later.
You need this service to have a stable website to see your camera outside your network later as 'ip' addresses can change but this site will remain stable.
Then after you log back in, create a 'host website' from the menu. When you are creating the host site, dyndns will give you lots of web address choices or you can create your own. Just pick one. Also, you will need the 'ip' of the server where the camera will be. Luckily the dyndns website tells you this, just select it. Write down the web address, click create and you are done this part.
Next you need to set up the camera.
CAMERA SET UP
Using an Ethernet cable, connect your Apple Base Station to your web cam.
You will need to run 'ip scanner' to see the 'ip' address for the web cam. Write down the 'ip'. Select it, then select "open device in". Pick browser.
A web page will be launched and you are given 3 choices. I picked the middle, 'push browser'. You are then asked for the user name and password for the camera. By default the user is 'administrator' and there is no password. Just click log in. You now will see a menu along the left, at the bottom it should say 'device management'. Select that. Another page will show and there are several important things to do here.
1. Alias - give a name to the camera.
2. Set the time from a server.
3. Users - set a user and password. Write this down as you will need it.
4. Basic network. Either check to 'Obtain IP from DHCP Server' or specify an IP you want to stay the same. You need the subnet and main DNS server and the Gateway (same thing like 192.168.0.?or 10.0.0.? or 172.16.0.?)
Decide on a port you want use. Write this down. The camera will reboot, you will need to log in. In the browser enter IP then : the port#. Like 192.168.0.?:80 you will need the camera user name and password.
5. Wireless-scan for the nearby network list. Pick your network, enter your password, click submit. It will reboot.
6. UPnP-check to use.
7. DDNS Service (this allows remote viewing) pick DynDns.org
Enter your DynDns user name and password.
Enter the long DynDns Host website you wrote down. Click Submit. It will reboot.
APPLE Basestation set up
Run Airport Utility on Mac or iPad or iPhone.
Tap basestation, tap edit, tap advanced, tap Port Settings, tap 'new entry', in description enter a name, enter HTTP port number you picked when setting up the camera in all 4 spots: public and private UDP and TCP. Enter the IP address you picked in the camera setup. Click done and again until the Basestation updates.
Run the CCTV app, pick 'tools', pick 'Port forwarding Checker'. Enter the port you selected to see if it shows open then you are good. If not go back through the steps.
Set up Foscam App on the iPad and iPhone.
Run App, tap Add Camera,
Label- enter a name
User- Camera user name
Password- Camera
Local camera address-the IP address eg 192.168.0.?
Port- the one you specified.
If it connects you will see the chain turn green.
Remote address- the long one from DynDns.
Port- the one you specified.
If it connects you will see the chain turn green.
Tap done.
If everything is entered correctly it will all work.
Trouble shooting, make sure the IP address for the camera is listed correctly in the Apple Router. If it changes on the network, just go into the Airport Utility and update that. Also make sure the dyndns address is correctly listed in the Camera set up.
If questions, just let me know.

Ok.. you have to work out the way you are going to access the TC..
There are basically three methods..
1. Direct access using AFP.. you need a static public IP and the TC as the main internet router.. then you need to turn on internet access and password the hard disk. The college has to have port 548 open.
If you do not have a static public IP then you can use ddns service but there is no client in the TC.. so you will have to figure out a way to update the service.
2. Use BTMM with icloud. This is the Apple method. It actually uses vpn..(the vpn is locked to apple use only but it is not available to end user).. The requirements are 7.6.1 firmware and lion or ML on a Mac computer. I am not sure of the ports because the link to the Apple cloud is separate from the vpn to your home system.
3. VPN.. that means you need to bridge the TC and use a decent quality vpn modem / router or combo thereof.
VPN are not for the faint of heart.. it can take a lot of work to get running but offers the best security.. you will need to change the network equipment in your house more than likely.. using a pc / mac as a vpn server is possible.. but messy.
There are also easy ways to at least access the home computer.. teamviewer for example. This is likely blocked by the college though.
Double NAT is where you put a router on a private IP behind another router on a private IP.. that makes port forwarding close to impossible.

Change System Status of SO item dynamically based on Reason for Rejection

Hi ppl,
Our SAP user has raised a requirement as described below:
In sales order (in creation mode (VA01) or change mode (VA02)), if at the item level, the reason for rejection is mentioned, then the system status for that item should be automatically set to Technically Complete SET (TECO); and if the user removes the reason for rejection for the item, then the system status Technically Complete should be RESET automatically.
We are looking for any user-exit or BADI available which would be allow this dynamic change of system status based on the reason for rejection field. (No manual interaction for setting or resetting the system status).
Technically, the functionality is based on the below fields:
Reason for Rejection: VBAP-ABGRU
System Status: JEST-STAT
Please provide suitable inputs.
Thanks,
Dawood

Does the information specified in Note # 236618.1 - OA Framework Personalization and Extensibility Guide: Version 5.7+
under the Section : Create/Update View Page
is related to this?

Check that you have specified the HEIGHT and WIDTH properties of the spacer!
Also, you have created an item, but make sure that it is RENDERED=TRUE at the personalisation level for your responsibility.
It is good prectice to create an item and render it FALSE. Then go to the specific personalisation level you require and set RENDER=TRUE.
Also, there is a better document than the one you refer to. Try looking at MetaLink document id 268969.1 - Oracle Framework Personalization Guide (OA Framework 11.5.10).
Let me know if that helps.

How to set a lable as the dynamic session variable ?

I have created a dynamic session variable in admin tool and then I want to create a prompt in dashboard and set label to use this session variable
I try to use the @{variable} or @{system.variable} in the label text ,but it is not work ,so what is the correct way or does the obiee not support to do like this?

thx, for responded
but I have read a topic said if left the label text empty the reference a presentation variable , then it can work , you can see it below:

Header and Item Odata through SEGW

Hi,
I know that this Topic was raised million times, but still raising this query. I have already consulted http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/e0d92637-3d0d-2f10-ebb2-efc1f40a85e8?QuickLink=index&… link.
Requirement: Create Header and Item Odata THROUGH SEGW.
Steps I have followed:
1. Created Header and Item Structure and have added them in the Export Parameters of an RFC.
2. Created the RFC and have populated the the internal tables corresponding to the Header and Item structures.
3. Go to Transaction SEGW and Imported the Header from the RFC. Then created Read and Query mapping for Header.
4. Go to Transaction SEGW and Imported the Item from the RFC. Then created Read and Query mapping for Item.
5. Created an association between "ID" of Header with "ID" of Item. Cardinality- 1:N
Observation:
Now when I run the Odata and execute /sap/opu/odata/sap/ZTEST_SRV/HDRSet(2)/ITEMSet, I get all the Items from the Item table for Each and every Header. But I guess for every header corresponding Items should have been enlisted.
Is there any step that I am missing?
Important: In the MPC class(ZCL_TEST_MPC), I could see a method named DEFINE_ASSOCIATION. I have put an external Breakpoint in it, but this breakpoint is not triggered.
-Regards
Dhrubajyoti

Hii Dhru,
In addition to the steps followed, you have to create navigation property using association created.
You have to implement Get_expand_entityset method in DPC method for multiple headers and corresponding items and for single header and corresponding items you have to implement GET_EXPANDENTITY method.
The URL is as format below :
/sap/opu/odata/sap/<service name>/<Header entity set>/?$expand=<navigation property from header to item>&$filter= eq '<ID>' '<value>'
Example URL : https://<server>:<port>/.../<service_name>/SalesOrders?$expand=SalesOrderItems
For reference :
https://help.sap.com/saphelp_gateway20sp08/helpdata/en/ca/c683e803494b77a2e1290b987556e2/content.htm
When GET_EXPANDED_ENTITYSET method invoked
For get_expanded_entity_set method implementation please refer the below URL

Can't set label

In CS2 I used this line
tell application "Adobe InDesign CS2"
set properties of every text frame whose label starts with "dude" to {label:"sweet"} of document 1
end tell
But in CS3 a strange error occurs
tell application "Adobe InDesign CS3"
set properties of every text frame whose label starts with "dude" to {label:"sweet"} of document 1
end tell
Now the weird part is if you just look for page items or text frames that start with label "bla bla" it works perfect but you can't set the label to anything.

Nevermind this fixed it
tell application "Adobe InDesign CS3"
tell document 1
set label of every text frame whose label starts with "dude" to "sweet"
end tell
end tell
Strange I had to dumb down the code for it to work. In CS2 it see the property approach always worked.

Setting a Filter on a dynamically created Table

Hi All,
I am currently working on a Database to automatize some process. Quick explanation:
The User can import a CSV (Text) File via a DialogBox, which gets imported into a Table. After this, the content has to be filtered, setting conditions on 4 different rows. The new Table gets exported into a new CSV (It has to be CSV, since it later gets imported
into SAP)
I am having some trouble with filters though:
How can I set a Filter on a dynamically created Table (using VBA)?
Best case would be to save the filter into my Import spec, but Access doesn't seem to have this option (?)
Can somebody help?
Thanks in advance
Regards
Alex

Thanks for the fast reply! Sorry, I am not really proficient at Access. How do I do a query on a dynamically created Table? Do I have to save the Table into a Variable. Or what's the way to import it?
Hi Alex,
I never use the Import functionality, nor DoCmd.TransferText.
To import data from a csv-file I made my own Import functionality. In fact it is just reading an external file, line by line, and each line field by field using the field separator. In my opinion that is far more versatile than the standard functionality.
But you can use the standard functionality of Access to import a csv-file into a table.
Having the data in a table, you can generate the appropriate query for the output in a VBA procedure:
sql_string = "SELECT Field1, Field2, ... FROM MyTable WHERE Field1 = ... AND Field2 = ... ORDER BY Field3"
and make a recordset of it:
Set cur_set = CurrentDb(sql_string)
The output csv-file is then filled by opening a file for Write, loop through all the records, concatenate for each record all the wanted fields using the field separator, and write the result line to the csv-file.
Most important is to understand this process. After that it should be possible to build it. And if you have further questions, just ask.

Hi Gurus,
I wanna print a TO label for each item ,
i have a TO with two items, and i go to OMLV ,set 3 (No.of labels = 1.(for each TO item,qty in alt un.of meas )) in field 'quantity of labels(indicator)', i was expecting that two labels will be printed out, but actually, just one label was printed out?

You can not create items at run time. But you can manage them at run time by setting Visible property programatically.
Hope this helps..
