Add numeric value to Table Column

Hello,
my problem:
I have a VO with a numeric attribute (Sal). This VO is shows in a table in a JSF Page.
I need to add to the column value a numeric value.
I try with #{row.bindings.Sal.attributeValue*2} or #{row.Sal+2} or #{row.Sal.inputValue+2} But I get an error.
Can someone help me ?
Thank You
JDev 11.1.3

Hi,
an option would be to use a transient attribute in the VO to compute the maths or to populate the column field from a managed bean. You can point the column field to a managed bean property (say sumSal). In this method getSumSal() you
1. Use ELContext, ValueExpression, and ExpressionFactory to resolve the #{row} reference (you can cast it to oracle.jbo.domain.Row
2. call row.get("attribute_name") to access the field value
3. Perform the computation and return the value to display in the table
Note that using a transient attribute may be easier to achieve and easier to reuse in other usages of the VO. However, you have to options

Popup Key LOV, NULL and "Invalid numeric value undefined for column"

Hello.
I've created an item based on database column of NUMBER type and set the following properties:
Display As = Popup Key LOV (Displays description, returns key value)
List of values definition=select 'display_value' d, 1 r from dual
Null display value=%
Null return value=
Display Null=Yes
When I select "%" in the LOV and try to apply changes to database I get error:
ORA-20001: Error in DML: p_rowid=1781, p_alt_rowid=N1, p_rowid2=, p_alt_rowid2=. ORA-20001: Invalid numeric value undefined for column N2
Error Unable to process row of table TTT.
If I set Display As = Select List, all works fine. But I need Popup Key LOV.
Could anybody help me?
I use Application Express 2.2.1.00.04

Hi all,
I did my homework and solved this issue. First I would like to thank Patrick Wolf for the invaluable help he gives out on thread Re: Null value handling in LOVs The code presented here is just a minor edit to his code, but an essential one when dealing with Popup Key LOV items.
Here's what I did:
1. Create an Application Process.
Name: RemoveNulls
Sequence: 0
Point: On Submit: After Page Submission - Before Computations and Validations
Process Text:
BEGIN
    FOR rItem IN
      ( SELECT ITEM_NAME
          FROM APEX_APPLICATION_PAGE_ITEMS
         WHERE APPLICATION_ID   = TO_NUMBER(:APP_ID)
           AND PAGE_ID          IN (TO_NUMBER(:APP_PAGE_ID), 0)
           AND LOV_DISPLAY_NULL = 'Yes'
           AND LOV_DEFINITION   IS NOT NULL
           AND LOV_NULL_VALUE   IS NULL
    LOOP
        IF (V(rItem.ITEM_NAME) = '%null' || '%' OR V(rItem.ITEM_NAME) = 'undefined')
        THEN
            Apex_Util.set_session_state(rItem.ITEM_NAME, NULL);
        END IF;
    END LOOP;
END;Error Message: #SQLERRM#Condition: None
2. You should be able to submit a Popup Key LOV with a NULL value now.
Once again, THANKS, Patrick! You rock! I'm seriously thinking of trying ApexLib now :)

How do I add numeric values as text in XML??

HI,
So, I've developed a 3d carousel using this tutorial and the XML, and customized the XML in Dreamweaver.
http://www.gotoandlearn.com/play?id=33
Now, I've got the carousel set up exactly the way I would like, but the only trouble, is how do I add numeric values as the text for the xml file???
Here's an example to the working carousel and where text is loaded for each item on it. (put your sound on mute if you don't want to hear the video)
http://iongeo.com/collaboration_test_dev/video_arctic_imaging.html
For example, in my XML, if I would like the text to be "3d images", when I export the FLA, only "d images" comes through because the numeric values can't be added as the text for the tooltip.
Does anyone have any ideas?
Here is an example of how the XML is loaded into the .swf - the text loads great, but just not the numeric characters.
The same story can be said for special characters, I would like to know how to add a "&" sign too.
<icons>
<icon image="images/Subsalt_E_P_Partnerships.png" tooltip="3D Images" content="Text Copy.">
</icon>
</icons>
Any help would be greatly appreciated.
Thank you.

Hi Randy,
Thanks a lot for the reply. Your post got me thinking that it's actually a flash problem, as the actual descriptor text shows 123,etc and "&".
The trouble is that the icons are dynamically loaded from the XML to movie clips on the flash file. I've asked the flash forum to see if they could take a look.
Thanks again.

WebDynpro ABAP - Display Short Text instead of values in table column.

Hi WebDynPro Experts,
    i have Column in a table which displays subject. This column has domain associated ZDE_SUBJECT with fixed values & short text
Fix.Val    Short Text
01             Level 1
02             Level 2
03             Level 3
04             Level 4
05             Level 5
when i bind this cloumn to a table UI element. And have records for this table. At runtime inside the table column. i see values returned as 01, 02 , 03 ( basically fix val) my requirement is to display the corresponding short text. Is there any easy approach to do this???

Hi Prash
I think you need to bind the short text values to the table UI.
I am not sure if there is any other easy approach for this.

Sql Loader INFILE name value in table column Value

Hi,
Here is my Sql Loader Script
LOAD DATA
infile '%1'
APPEND INTO TABLE XX_SUPPLIER_UPD
FIELDS TERMINATED BY ";" OPTIONALLY ENCLOSED BY '"' TRAILING NULLCOLS
ACTION Char
,ADDRESS_TYPE Char
,REGION Char "LTRIM(RTRIM(:REGION))"
,PO_BOX Char
,,WWW_ADDRESS Char
,status Char "NVL(:status,'X')"
,filename Char "replace(:infile,'\"','')"
I am getting the infile name as the parameter and i want to insert that parameter value in the column name fillename. Can any one guide me to how to do.
Cheers!
Jayaraj.S

If you were to use external tables instead of SQL*Loader, you can dynamically change the location of the external table (i.e. the filename) using a simple ALTER TABLE statement.
External tables also mean that all the control is inside the database rather than relying on external utilities and external scripts.

Query only non numeric values in a column

How to query only non numeric values in a cloumn.
For example:

4 DKFI*
5 3J6
Query should retrieve only rows(2,4,5).

Version 2(PL/SQL) above is not clear enough, It can be tuned to the following:
-- Create a function
Create or replace function IsVARCHAR(pCol VARCHAR2) return VARCHAR2
AS
vNumber NUMBER := 0;
begin
vNumber := to_number(pCol);
RETURN NULL;
Exception
When Others Then
RETURN pCol;
End;
-- To See VARCHAR values (alpha-numeric) only!
SELECT col1 FROM tab1
WHERE IsVARCHAR(col1) IS NOT NULL;
-- To See NUMBER values only!
SELECT col1 FROM tab1
WHERE IsVARCHAR(col1) IS NULL;Versatility here with PL/SQL, but I personally like SQL versions.

Retrieving numeric values of a column from another table..

Hi there, so i have the following query that returns a label and a value from a database table:
select key_field,value_field from table1 where some_id = 'id1' and key_field is not null;
This will return a result in which the key_field may or may not be numeric, which is fine:
key_field | value_field
2 | street
6 | dog
car | mazda
5 | tea
1 | unknown
I have another table table_num_vals where the value for those numeric fields are stored:
key_field | display_field
2 | address
6 | animal
5 | drink
I want to be able to return the non-numeric fields as they were, all numeric fields translated if it can be found, and if not then leave the original number, desired result:
key_field | value_field
address | street
animal | dog
car | mazda
drink | tea
1 | unknown
I tried doing the following:
select display_field from table_num_vals where key_field in (
    with numericCol as (
        select key_field from table1 where some_id = 'id1' and key_field is not null;
    ) select case when regexp_like(key_field,'^[[:digit:]]') then key_field else '' end from numericCol
It gives me the labels for the ids that it can find.. (address, animal, drink) but then I can't seem to put it all together with the original query.. could someone please help?
Thanks in advance,

Yes you are right .. Thank you so much
I let it work using
select student_ID, Level from Student where Level ='Graduate'

ShortDescCell
ShortDesc

Can anyone help me please in how to go into the table --> row --> column to retrieve the value from a specific column?
If their is a document or example that can help I will appreciate it. Since I tried searching in devguide and didn't find any results.
Note: I am extending the controller and reached till the following code:
public void processFormRequest(OAPageContext oapageContext, OAWebBean webBean){
super.processFormRequest(oapageContext, webBean);
String event = oapageContext.getParameter("ShortDescRow");
OATableBean advtable = (OATableBean)webBean.findChildRecursive("SearchResultsTableRN");
OARowBean rowtbl = (OARowBean)advtable.findChildRecursive("DetailsCell");
String message = "test:"+event+"|"+advtable+"|"+"|"+"|"+"|";
throw new OAException(message, OAException.INFORMATION);
Thanks and Regards
Patrick

Patrick,
My first advice would be go through OAF guide and do tutorial examples, for such basic details.
If ur talking about tablelayout region
u can use pageContext.getParameter(<Item id of UIX bean whose value u want>);
If you are talking about table
You can Iterate through the VO based on primary key ...on which the table is based, and retrive the corresponding Vo attribute value.

Add Sequence Value to table

Hello, I have a table that uses a sequence as a primary key. My question is, how do you add the NEXTVAL to a row when you are in the data section of that table. I tried adding mysequence.nextval, but when I commit the row, it takes it as a literal string.
Thanks, sck10

As said in following threads, you can't:

How to insert parameter value into multiple columns and rows

Hi All,
I have one procedure insert_tab and I am passing
100~101~102:103~104~105:106~107~108 as a parameter to that procedure. I wanted to insert each numeric value into one column. The output of the table should contain

Type conversion from numeric value to time format

hi guys,
i hvae column called (Time in seconds).i need to convert the numeric value of one column into time format HH:MM:SS. for example 3012 =00:50:12.
how can i proceed the same in the front end.
Thanks & Regards,
Nandu

Hi..
here is the code.. (assuming 10000 in the following code is your seconds, replace that with your value...)
cast(TRUNCATE(10000/3600,0) as varchar(2)) || ' : ' || cast(TRUNCATE(60*((10000/3600)-(TRUNCATE(10000/3600,0))),0) as varchar(2)) || ' : ' ||cast(60*((60*((10000/3600)-(TRUNCATE(10000/3600,0))))-(TRUNCATE(60*((10000/3600)-(TRUNCATE(10000/3600,0))),0))) as varchar(2)) You can also use floor instead of truncate...
Above will give only h:m:s format if hh (or) mm (or) ss are between 0 and 9. So, you may need to add case when condition before each concatenation: if hh is between 0 and 9 then need to concatenate with 0 else the same code...
Thanks...

How to display 'Alpha numeric values' in lower character?

Hi,
We have 'Alpha numeric value' in one column and i need to display alphabets in lower character.
I tried but throwing error.
SQL> select * from a439487.ora_dev_inventory;
HOST_NM HA INV_DT
SMMK94 - 21-AUG-08
SQL> select to_lower(HOST_NM) from a439487.ora_dev_inventory;
select to_lower(HOST_NM) from a439487.ora_dev_inventory
ERROR at line 1:
ORA-00904: "TO_LOWER": invalid identifier
I want 'HOST_NM' to be displayed in lower value.
I need o/p like 'smmk94'.
Any idea?

Where did you find the TO_LOWER function? Can you
show us?I would guess it was just an assumption based on the fact we have to_char, to_date, to_number...

Whats the available privileges on a table column

Dear all,
i want to know whats the available privileges that i can assign on a table coulmn.
and the revoke privileges
Best Regards,
Shooosh

If I have well understands, the principals are
The following are the object privileges that can be granted to users of the
database:
SELECT Grants read (query) access to the data in a table, view, sequence,
or materialized view.
UPDATE Grants update (modify) access to the data in a table, column,
view, or materialized view.
DELETE Grants delete (remove) access to the data in a table, view, or
materialized view.
INSERT Grants insert (add) access to a table, column, view, or
materialized view.
EXECUTE Grants execute (run) privilege on a PL/SQL stored object, such
as a procedure, package, or function.
GRANT SELECT, UPDATE ON CUSTOMER TO JAMES;
You can revoke a user’s object privileges and system privileges by using the
REVOKE statement.
but I believe that you am more profit reading manual: dba administrator or sql reference
