Display as Text: Source or computation/process?

I have a bunch (about 10) of Display as Text (does not save state) items on a page.
The source for all these items is a single row in some table.
I see 2 alternatives to populating these items
1. Specify the Source attribute for each item as the SQL query select colN from mytable where pk=:P1_PK2. Write a onLoad process to load up all of them at once using
select col1,col2,col3,...colN
into :P1_COL1,:P1_COL2,:P1_COL3,...:P1_COLN
from mytable
where pk=:P1_PK;It would seem that (2) is the more performant option because it queries "mytable" only once and gets all the values. Whereas (1) queries the table N times.
Unless (I doubt this, but just want to make sure), the Apex show engine internally detects that the Source query for all the items can be "combined" into 1 query and the values returned can be doled out to the individual items.
Comments?
Thanks

You could use an Automated Row Fetch process if the column names are not already spoken for by such a process. Otherwise, stick with option 2. APEX does not optimize stuff like you described.

Javascript not working with 'Display as Text (does not saves state)'

Hi,
We have these following items in P3 of our application,
P3_EDIT_ACCOUNT Display as Text (saves state)
P3_USEFUL_LINKS Display as Text (saves state)
P3_LAST_APPROVED Display as Text (saves state)
P3_ARCHIVES Display as Text (saves state)
And we are initializing these items in a pl/sql process under 'Page Rendering'
For example,
:P3_ARCHIVES := '<font face="Arial, Helvetica, sans-serif" size="-1">Archives</font></a><td> ';
When our environment was upgraded from HTMLDB1.5 to HTMLDB2.0,
instead of displaying the proper value of :P3_ARCHIVES,
it was displaying the tags,
i.e. instead of displaying 'Archives', it was displaying the whole
'<font face="Arial, Helvetica, sans-serif" size="-1">Archives</font></a><td> '
So, when we changed all items to 'Display as Text (does not saves state)' and it was working.
But then we have another problem,
We render the rest of the same page with another pl/sql block,
Here is a portion from that pl/sql for your reference,
htp.p('
<script>
//Script to check the status change.
//The script source is rendered through PL/SQL.
function checkStatus()
var promptStr = someString;
if(ans.toUpperCase() == "AMBER" || ans.toUpperCase() == "RED")
          var cnfm = confirm(promptStr);
          if(cnfm)
          do something....
</script>
htp.print('
<td width="5%" bgcolor="#ebebc5" height="19" align="middle" >
<input TYPE="radio" name="'||l_g_fnumber||'" value="GREEN"');
IF l_allow_update THEN
     htp.print(' onClick="checkStatus()"');
ELSE
htp.print(' disabled onmousedown="return false;"');
                    do something....
Now the issue is , when we changed all items to 'Display as Text (does not saves state)', the checkStatus() function is not getting called in the onClick
event of the radio button and hence the confirm window for the call to
confirm(promptStr) is not coming up.
But if we revert back the items to 'Display as Text (saves state)',
the checkStatus() javascript function is getting called properly but html tags are displayed against the items instead of the proper value (as mentioned in ********)
Please do let us know a possible solution to this issue.
Thanks & Regards-
Rupak

Thanks Varad for your response.
This is the error i am getting.
1 error has occurred
PLSQL anonymous block source type can be used ONLY with Display Text (based on PLSQL) item type.
yes i am using in the source..
I also tried with the PL/SQL Expression of FUNCTION in this case it is executing the query but once i run the page ora- 06550 error occured.

Display as Text field won't populate from select

I'm an Oracle Forms person trying to learn APEX. Love it but having problems with seemingly simple stuff. I made a simple page exactly from sample code found from Oracle documentation and still can't get to work. Appreciate any help.
Have simple form with 2 fields. One field P400_DEPTNO which is select field. Code in the HTML Form Element Attributes: onchange="javascript:getDNAME(this);"
The other field is D400_DNAME which have as Display as Text(escape special characters, does not save state)
I have application item G_DEPTNO
application process GET_DNAME:
DECLARE
vDNAME VARCHAR2(100);
BEGIN
SELECT DNAME INTO vDNAME FROM DEPT WHERE DEPTNO = :G_DEPTNO;
htp.p(vDNAME);
EXCEPTION WHEN OTHERS THEN
htp.p('No such department!');
END;
code in HTML Header of page 400:
<script type="text/javascript">
function getDNAME(filter)
var get = new htmldb_Get(null,&APP_ID.,'APPLICATION_PROCESS=GET_DNAME',0);
get.add('G_DEPTNO', filter.value);
var ret = get.get();
if(ret)
var d = document.getElementById("P400_DNAME");
d.innerHTML = ret;
get = null;
</script>
I'm getting this error when running page:
get error:
Line: 25
Char: 3
Error: 'null' is null or not an object
when I view source: line 25 is:
d.innerHTML = ret;
I have tried so many variations. Could something on my system not be installed correctly or am I just missing something simple? Appreciate any help offered.

Hi Vinad:
I am running version 3.0.0.00.20.
I followed the directions step by step from http://apex.oracle.com/pls/otn/f?p=56976:1:2691826935187310
I assume the code you are interested in is the javascript code:
HTML HEADER
<script type="text/javascript">
function getDNAME(filter)
var get = new htmldb_Get(null,$v('pFlowId'), 'APPLICATION_PROCESS=GET_DNAME',0);
get.add('G_DEPTNO', filter.value);
var ret = get.get();
if(ret)
var d = document.getElementById('P1_DNAME');
d.innerHTML = ret;
get = null;
</script>
On Demand Application Process
DECLARE
vDNAME VARCHAR2(200);
BEGIN
SELECT WHS_LST_NM INTO vDNAME FROM dw_tst.emp_dim@dm_dev
WHERE emp_id = :G_DEPTNO;
htp.p(vDNAME);
EXCEPTION WHEN OTHERS THEN
htp.p('No such employee!');
END;
Please let me know if you need any other information. Thank you.

Linebreaks in Display as Text items

See http://htmldb.oracle.com/pls/otn/f?p=24317:14:::::P14_PK:3061
The same item (CLOB) is displayed as a editable textarea and as a Display as Text item.
The Display as Text item type eats up all the linebreaks in the data since it is rendering HTML markup where whitespace, linebreaks are irrelevant.
How can I preserve the line breaks in the Display as Text item?
I guess I can wrap it in a PRE tag but that would change the font, I would like to keep the same font just preserve the linebreaks and whitespace.
Thanks

Hi,
I have a Page Item P7_LAST_ACTION
Display as: Display as Text (saves state)
Source Type:
Database Column
Source value or expression
LAST_ACTION
Post Calculation Computation
replace(:P7_LAST_ACTION,chr(10),'<BR>');
But it doesn't replace.
I have the same info in ACTION db column in a query
select "ACTION_ID",
replace(ACTION,chr(10),'<BR>') Task,
"DESCRIPTION",
from BH_ACTIONS
It displays fine...
(with newlines, blank lines - <BR><BR>)
Both column types are the same:
ACTION VARCHAR2(2000)
LAST_ACTION VARCHAR2(2000)
any ideas? Bill

Incoming mail won't wont display rich text or graphics

. Before updating my Intel iMac to Leopard, none of my incoming mail displayed the text or graphic that it was used to compose the mail i.e everything is in plain text . I took the computer to local Apple store and paid for 2 hours of the tech's time and he could not find the source of the problem. After upgrading to Leopard, it did improve a bit with some mail displaying the graphics and rich text but now it is happening again.
I have been into Mail preferences and ticked the box "display remote images in HTML messages " . There is nothing in troubleshooting to help and it is getting annoying. I also have a 13" Macbook but it does not have the same problem as the rich text and graphics come through as sent. Hope someone can help.

Problem in Displaying Subtotal text in Grid Display

Hi Experts,
             I got a problem in passing the Subtotal text and Total Text in Grid Display.In my Case we are calculating Interest Rate for Document Number for Each Assignment Number. If any discount is maintain for document, calculate the interest rate as per the given formula.
           So, in this case, Instead of Subtotal text, we can view the 2 dots in Grid display. But in the place of that or else, i want to display the Subtotal. But this not happen in case of Grid Display, I tried in List Display, i can able to display the text.
Here is the Code what i maintain.
wa_sortcat-fieldname = 'ZUONR'.
wa_sortcat-tabname   = 'IT_FINAL'.
wa_sortcat-subtot    = c_x.
APPEND wa_sortcat TO sortcat.
wa_sortcat-fieldname = 'BUDAT'.
wa_sortcat-tabname   = 'IT_FINAL'.
APPEND wa_sortcat TO sortcat.
wa_sortcat-fieldname = 'INTER'.         "Interest Rate
wa_sortcat-subtot    = c_x.
wa_sortcat-tabname   = 'IT_FINAL'.
APPEND wa_sortcat TO sortcat.
Fieldcatalog:
    wa_fieldcat-outputlen    = c_15.   " Interest Rate
    wa_fieldcat-do_sum       = c_x.
Layout:
alv_layout-colwidth_optimize = c_x.
alv_layout-zebra                    = c_x.
alv_layout-subtotals_text       = 'Subtotal'.
alv_layout-totals_text              = 'Total'.
I check in the SDN, But in some Threads, They explain as, We cant display the Subtotal text in Grid display.
Please help me to sort this issue. And clarify this whether this is possible or not.
Thanks in Advance.
Srini

Hi Naresh,
    Thanks for your reply, I added the given code by you to fieldcatalog for Interest rate field. i.e.
    wa_fieldcat-outputlen    = c_15.
    wa_fieldcat-do_sum       = c_x.
    wa_fieldcat-inttype      = 'I'.
Is this is a correct process what you are thinking, or i had to declare for every field what i declare under fieldcatalog.
Regards,
Srini

How to set "Display as Text" field with AJAX select list

thanks Denes for your posting. I'm trying to use the Denes Kubicek code to populate a "Display as Text" field. It works for Text Field (disabled), but not "Display as Text" field(saves state) . In my applciation I need to show this field only (not the disabled text box) when a select list value is changed. any ideas to modify the code below are appreciated.
http://htmldb.oracle.com/pls/otn/f?p=31517:80:3418128396960418::NO
here is the code from the url above
1. Create an Application Process - getDet:
DECLARE
my_det VARCHAR2 (200);
BEGIN
SELECT ename || CHR(10) || job || CHR(10) || mgr
INTO my_det
FROM emp
WHERE empno = :P80_EMPLOYEES;
HTP.prn (my_det);
END;
2. Put the following in the Region Header of your page:
<script language="JavaScript" type="text/javascript">
function f_getDet ()
var get = new htmldb_Get(null,&APP_ID.,'APPLICATION_PROCESS=getDet',0);
get.add('P80_EMPLOYEES',html_GetElement('P80_EMPLOYEES').value)
gReturn = get.get();
if(gReturn)
{ html_GetElement('P80_DETAILS').value = gReturn }
else
{ html_GetElement('P80_DETAILS').value = 'null' }
get = null;
</script>
3. Put the following in the HTML Form Element Attributes of :P80_EMPLOYEES:
onChange="f_getDet()";

Arie,
this works fine on normal page, except page zero. I have the AJAX select list and "Display as Text" field on page zero. The "Display as Text" field doesn't show the the value when AJAX select is changed. I'm using similar code as used in my other APEX page on OTN site. I tired to display the gReturn value, just before calling "setDisplayOnlyNode" function in the code below and it's showing correct value, but fails to display the value in the APEX field on page zero. Any ideas are appreciated.
Thanks,
Surya
<script language="JavaScript" type="text/javascript">
function setDisplayOnlyNode(pItem, pValue)
{ var textNode = pItem + '_DISPLAY'; $x(textNode).innerText = pValue; }
function f_getDet ()
var get = new htmldb_Get(null,&APP_ID.,'APPLICATION_PROCESS=getDet',0);
get.add('P1_EMPLOYEES',html_GetElement('P1_EMPLOYEES').value)
gReturn = get.get();
if(gReturn)
{ setDisplayOnlyNode('P1_DETAILS',gReturn)}
{ html_GetElement('P1_TEST').value = gReturn }
get = null;
</script>

Display a text in multiple lines inside a button

I have a toggle button bar containing many buttons as follows:
<mx:ToggleButtonBar id="menu"
     itemClick="clickButton(event)"
     styleName="myToggleButtonBarStyle"/>
The styles apllied are :
<mx:Style>
          .myToggleButtonBarStyle {
               button-style-name: "buttons";
               vertical-center:0;
     .buttons {
          text-selected-color: #14476c;
          text-roll-over-color: #14476c;
          up-skin: Embed(source="/phase_grey.png");
          over-skin: Embed(source="/phase_blue.png");
          down-skin: Embed(source="/phase_blue.png");
          selected-up-skin: Embed(source="/phase_blue.png");
          selected-over-skin: Embed(source="/phase_blue.png");
          selected-down-skin: Embed(source="/phase_blue.png");
          padding-left:45;
          padding-right:30;
     </mx:Style>
My problem is that when I have a long text, it is displayed in one ligne so the button get larger. I do not want my button to get larger it has to keep the initila size (my button is an image). I want indeed to display the text in multiple lines rather than only one.
How to do this?
Thank's in advance

Designer form displays differently on different similar computer.

I created an Adobe LiveCycle Designer 7.0 form which contains various text fields and numeric fields. All the form's fields display correctly on my own computer (WINXP Pro) when a user inputs data to the fields. When posting the form to the web those fields continue to display correctly. However, if my wife enters data to the form on the web these same fields do not display (or print) correctly. (Her computer is a WINXP Pro as well and also has Adobe LiveCycle Designer 7.0 installed). The form appears to be "dropping" the bottom of some letters (the descender portion of the letters) and some numbers, though not all. To solve the problem, I redesigned the form using Arial 10 pt instead of "Myriad Pro" 10 pt but it makes no difference. To show you what I mean, I posted 2 screen shots at http://www.lepirtle.com/acrobat using test letters and numbers in some of the fields. The first screen shot is the way it appears on my computer (the way I want it to look) and the second shot is the way it appears on my wife's computer: the descender portions of the letters and some, though not all, of the numbers are "dropped".
Can anyone offer a solution? Thanks.

To answer banh29's question: My wife's computer has exactly the same version as me: Acrobat 7.02 Pro. To answer Hubert's question: yes, both her computer and mine are set the same, "Font size Normal".
However, in the last couple of hours I found the solution to my problem. I set the Layout property of the "Y" dimension to "Expand to fit". This prevented the "bottoms" of the numbers and the letter descenders from disappearing.
I am still puzzled why the forms appear differently on each of our computers however. I thought that was the great thing about Acrobat in that things appeared the same on all computers.
Thanks for your help.

DISPLAY AS TEXT (DOES NOT SAVE STATE)

can i use the pl/sql anonymous block or pl/sql function body for item which is DISPLAY AS TEXT (DOES NOT SAVE STATE). I am using this query and getting an error in case of pl/sql anonymous block can be used only for save state item. my apex version is 2.2.1.00.04.
my query is
declare
vCNT number;
v_exception_detail varchar2(200);
BEGIN
SELECT COUNT(*)
INTO vCNT
FROM table a
WHERE a.col1 IN
(SELECT DISTINCT x.col1
FROM table1 x)
AND a.col2 = TRIM(:P21_col2);
IF vCNT > 1 THEN
IF NVL(&P21_col2, -1) <> -1 THEN
SELECT DISTINCT SR.col3
INTO v_exception_detail
FROM table1 SR
WHERE SR.col1 IN
(SELECT col1
FROM table
WHERE col2 = TRIM(:P21_col2)

Display as text based on pl/sql - how to return value

Hi,
I have a item set as "display as text based on pl/sql". How do I get the PL/SQL anonymous block to return the value of the item?
My function declares and populates a variable called t_output which is the value I want displayed in the item. The PL/SQL I have written is correct as I have tried it in SQLPlus* with DBMS_OUTPUT.PUT_LINE and I get the correct output, but I don't know how to set my item to the value of t_output. I have tried adding ":P73_ITEM := t_output;" into the end of the PL/SQL block.
Thanks
Lucy

Hi Lucy,
Try this and see.
make the display as:display as text(saves state)
source type: sql query
in source value or expression type
select func(arguments) from table name;
Good luck

Display as text (based on LOV) not working

hi --
I've not used this kind of item before, so there's probably some really simple thing I'm missing....
Have the LOV:
select objecttype_name display_value, objecttype_id return_value
from hdb_objecttype_syn order by 1
Return value is going into page item :P3_objecttype_id (a popup LOV). Have another item, :P3_objecttype_name, which is a display as text (based on LOV) item. When/how is this item supposed to get populated? When I select a value from the LOV, I'd expect the text item to be set to the display value of the LOV, but it is always []. The source type of :P3_objecttype_name is Sql Query, and the query is:
select objecttype_name from hdb_objecttype
where objecttype_id = :P3_objecttype_id
Does the page have to be submitted before the display item is populated? Seems like that wouldn't be very helpful...
Thanks,
C

HI Varad -- I'm afraid I'm new enough to all this to not know how to implement either of your solutions... and that's after scanning the forum for additional info.
How do I get the page to submit? Is there any way to do this w/o forcing the user to explicitly press a button? (which would be way too much, as there are probably 10 LOVs on this page).
If I choose to use javascript, 1) on what item and under what attribute do I put the script (is it on the objecttype_name that needs to be populated?), and 2) where can I find an example of what this might look like? I'm not familiar w/ it at all.
My goal is ultimately to have an LOV that displays both the key value and the name (which I guess can be accomplished by concatenating those together in the LOV select statement), to return the name to the page, and then have the ID automatically filled in to match the key (the example I sent you is backwards, simply because I started building this page w/ only key values displayed, added the name as a test later.) And, I also want the user to be able to type in the ID (no LOV would be attached to it), and have the name automatically populated. I'm guess this could be accomplished in a way similar to having the name filled in after the value is chosen from the LOV... If I can just figure out how to do that!
Thanks,
Carol

Convert numeric value to display as text based on record in another table? ASP/VB

I have an orders table:
orderID (PK)
pickupname
pickupaddress
pickupregion (numeric)
pickuppostcode
deliveryname
deliveryaddress
deliveryregion (numeric)
deliverypostcode
I also have a regions table:
regionID
regionname
On my ASP page, I would like to display the pickup and
delivery addresses as
follows, but also need this to be within a repeat region as I
am displaying
a number of orders on the page (I have wrapped what I want in
the repeat
region in dashes, below):
---------Repeat Region Start-----------
Pickup Address:
Name
Address
Region (pickupregion)
Postcode
Delivery Address:
Name
Address
Region (deliveryregion)
Postcode
--------Repeat Region End------------
As it displays at the moment, I get this (using sample data):
---------Repeat Region Start-----------
Pickup Address:
Joe Bloggs
High Street
12
HT12 5TY
Delivery Address:
Jane Bloggs
The Mall
33
DT6 5TG
--------Repeat Region End------------
Is there any way to convert these numeric values to the
actual region name
but to keep it within one recordset so that I can use the
repeat region? I
tried creating a recordset for regions (SELECT regionID,
regionname FROM
tblRegions WHERE regionID = pickupregion OR regionID =
deliveryregion), but,
because I'm not repeating this region, it just displays the
same regional
name for every order, albeit the first record returned does
contain the
correct values! :o)
I was thinking about some kind of inner join, but it's having
two numeric
region fields in the orders table that is causing me
headaches! PS. I need
to keep the two addresses within one orders table - I had
thought of that!
Got me a bit stumped, I have to say. Any help would be
greatly appreciated.
Thanks.
Regards
Nath.

I've tried this one already.
I tried to leave it blank, & nbsp ; , text,... but the problem is that our lov is build by a function and it always returns a query, so the LOV is never null.
I figured something out: made a process after header that has some cursors to get the values from the database and changed the item to a simple display as text-field. There were only 4 that were wrong, so it wasn't to much work.

Cannot display the text in Hyp Planning via ODI

Hi,
has anyone follow the tutorial from John Goodwin here:
"http://john-goodwin.blogspot.com/2008/10/odi-getting-text-data-into-planning.html" ??
I'd tried the tutorial in order to able to display text in Planning.
However, I still cannot display the text in the end, only the numeric id values - taken from the HSP_TEXT_CELL_VALUE table.
Here the steps I've done:
- getting the list of id and text values to be inserted into HSP_TEXT_CELL_VALUE table
- make a new interface to load data into planning
- I want to load data from flat file to Planning, so I dragged flat file and also the HSP_TEXT_CELL_VALUE table into the source column, and then join the "MP3" column from flat file with values column from HSP_TEXT_CELL_VALUE table (like written in the tutorial ""http://john-goodwin.blogspot.com/2008/10/odi-getting-text-data-into-planning.html")
- after that, I dragged the Account dimension, and then join them. For the MP3 column in target column, I mapped it with "id" column from HSP_TEXT_CELL_VALUE table.
- Then I execute. The data loaded into Planning, but when I tried to open in report, the MP3 column shows the "id" instead of "values".
Am I missing something?
Has anyone experienced the same as mine?
Any help would be appreciated.
Thanks

Hi,
I may have followed the blog :)
First have you loaded the values into the HSP_TEXT_CELL_VALUE table, have you checked the values are now in the table ?
Also, you will unfortunately have to restart the planning service after you have loaded them as the table is cached and a restart clears the cache.
When you load into planning you need to map the "Value" field in HSP_TEXT_CELL_VALUE to your data source, and load in the id to planning.
If you are only getting numerical values it is either because you have not restarted planning or the HSP_TEXT_CELL_VALUE has not been updated correctly.
Cheers
John
