HTMLDB_ITEM ... Help

Hi I have the basic update form as shown below... I am trying to capture the data that is associated with the checked rows...
Report with checkbox:
select htmldb_item.checkbox(1,empno) empno,
ename,
htmldb_item.select_list_from_query(3,job,'select distinct job, job from emp') job,
htmldb_item.popupkey_from_query(4,mgr,'select ename, empno from emp',10) mgr,
wwv_flow_item.date_popup(6,null,hiredate) hiredate,
htmldb_item.text(7,sal,10) sal,
htmldb_item.text(8,comm,10) comm,
htmldb_item.select_list_from_query(9,deptno,'select dname, deptno from dept') deptno
from emp
pl/sql submit process to capture rows..
FOR I IN 1..HTMLDB_APPLICATION.G_F01.COUNT
LOOP
insert into test_table (pk) values ( HTMLDB_APPLICATION.G_F07(HTMLDB_APPLICATION.G_F01(i)) );
END LOOP;
Every time I run this process I get the following error...
ORA-01403: no data found
I am not sure why this is happening, I can insert HTMLDB_APPLICATION.G_F07(i) but it is not letting me reference "the seventh column" for each row that has been selected...
any ideas?

See Re: Problem with validation and tabular form
Indices for F07 go from 1 to number of rows rendered on the report.
f_07(f01(i)) evaluates to f_07(1234) if you select the checkbox corresponding to empno=1234.
Clearly, this will generate a ORA-1403 since you don't have 1234 rows in your tabular form.

Checkbox in tabular form - help needed

I'm trying to build a tabular form, with a checkbox for a field that can have value 'Y' or 'N'. Adding the checkbox is no problem, with the htmldb_item.checkbox API.
However, processing it is.
On this forum I found a way to process the checkboxes, by looping through all the records (with the help of htmldb_item.hidden in which the id is stored) and reading the value from the checkboxes and updating the column if the checkbox is checked. (see Re: Report with updateable checkbox)
however, as soon as I add a htmldb_item.hidden item, I receive the following error when I submit the tabular form to the Multi Row Update process:
"Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. "
My query:
Select id
,htmldb_item.hidden(1,id)
,htmldb_item.checkbox(2,id, decode(field, 'Y', 'CHECKED', NULL))
from table
What am I doing wrong?
is there a better way to process a tabular form with checkboxes?
Or should I process all the rows manually by updating every record even if it hasn't changed (with a loop through all the records)?

Tonnie, did you ever get an answer to this question?

Reports not retaining carriage returns from htmldb_item.textarea

Im created a tabular form for multi row updates using htmldb_item.textarea for one of the fields. When I update the tabular form it keeps any carriage returns in this field, which is good. I then created a PL/SQL function body returning a SQL Query report for printing purposes. The problem is that the field populated by the htmldb_item.textarea does not retain any of the carriage returns in the report.
I enter the following in the textarea on the tabular form:
Line 1
Line 2
Line 3
The report I created then displays the data as:
Line 1 Line 2 Line 3
I need the report to display the data the same as it appears on the tabular form.
I tried this in my report from reading other similar situations on this forums, but didnt work.
replace("TEXTAREA",''||chr(13)||'',''||
||'') as title
Anyone know of a solution?

How about this?
Go the page where you can edit the report column attribute - here is the bread crumb to help you figure out what I am talking about
Home>Application Builder>Application 99999>Page Definition>Report Attributes>Column Attributes
The second box in this page is Column formatting, you will find 4 text boxes (Number / Date Format, CSS Class, CSS Style, Highlight words) and a text area (HTML Expression). In the text area replace #COLUMN_ALIAS# with <PRE>#COLUMN_ALIAS</PRE>. You will get your newlines without tweaking the query or removing Strip HTML. Strip HTML is a security feature that I would not disable. On the down side you will loose some of the ability to format like fonts etc (:-(,
Here is why you loose the newlines in the report. When browsers render html they have the liberty to reformat it. When reformating they can play around with whitespaces including new lines. To force a new line you have to use the BR tag or you can say the text is preformated using the PRE tags.

Values for htmldb_item.text field do not display in CSV output

HTML DB experts,
I have a report query with the following 2 items in the SELECT statement:
wwv_flow_item.display_and_save(2, DOC_CD, 10) DOC_CD,
htmldb_item.text(3, DOC_DESC, 50, 255) DOC_DESC
I have enabled the CSV output for this report. The problem is, when I generate a csv file, only the DOC_CD (wwv_flow_item.display_and_save) displays. The values for the DOC_DESC (htmldb_item.text) do not display. What do I need to do to get the DOC_DESC to display?
Thanks for your help.

Items rendered using htmldb_item generate HTML tags on the form, not plain text. You are right, the CSV export excludes them.
Your best best is to create another report region on some other page with the same query except replace all the htmldb_item() calls with regular columns i.e. make it a read-only report and use the "export: CSV" template and put up a link to this page at the bottom of your editable report (instead of the builtin CSV link). This way when you click on this link, it will generate your report and immediately offer to export it to CSV
Hope this helps.

Why I cannot process a disabled field when using htmldb_item

I have a report that has this in the select statement
case when c.sec_lic_status in (1,2,7,505,1002,1004,1005) then
htmldb_item.text(2,sum( distinct a.fee_variable),8,20)
else
htmldb_item.text(2,sum( distinct a.fee_variable),8,20,'disabled')
end "Quantity 1"
The above shows correctly. If there are 2 records one field is disable and the other is enabled.
I have a process that fires on submit - after Computations and Validations. But the records don't changed when updating the enabled one.
In debugging and writing to a file using the UTL_FILE package, I'm able to pinpoint that the disable fields are the problem.
Is there a trick on manually processing disabled fields?
I've found that when I uncheck the show box in the report, I cannot use the fields either. This is not a problem, just another comment.
My main problem is what do I have to do to manually process a disabled field.
Thanks for your help, comments, pointers, or anything that could help me or give me ideas.
juan

Juan - HTML items with the disabled attribute are not POSTed with the form so your after-submit processes never see them. Try 'readonly="readonly"' instead. Others may be able to suggest how to also give those cells a greyed-out appearance.

Issue with CSV export while using HTMLDB_ITEM.SELECT_LIST_FROM_LOV in SQL

Hi,
I have created a SQL report with HTMLDB_ITEM package. IN that report, I have generated a report column using SELECT_LIST_FROM_LOV, which can be used by the admin to update the column entry.
Here is the link:-
http://apex.oracle.com/pls/apex/f?p=50508:8:
The update is working fine, The issue is, if you download this report as a CSV, it will export all the values of the select list for that particular column. Is there any way to restrict the export to the single value of that column( or the current value in the database). Please help/ suggest.
thanks

HTMLDB_ITEM.SELECT_LIST_FROM_QUERY looses commas from option texts

Hi,
I used HTMLDB_ITEM.SELECT_LIST_FROM_QUERY on my custom tabular form. Some of the option display values selected from my table have commas (',') in them, but commas won't get displayed in the resulting select menu, nor are they seen in html source. In the html source however I see that they are probably replaced with spaces (' '). Is it a bug and is there a workaround? Which symbols are replaced in the DISPLAY_VALUE and thus should be avoided (if there is no workaround I should include this information in the help text)?
Kaja Trees

Yet in my application there are two regions side-by-side on my test page, one with a query of
select htmldb_item.SELECT_LIST_FROM_QUERY( 10, 0
, ' select NAME as DISPLAY_VALUE
          , ID as RETURN_VALUE
          from OBJ_TPL_SELECT_OPTION'
     , ' class="search-table-input-long" ' -- make it longer
     , 'YES' -- show empty choice
     , '0' -- empty choice value
     , '...' ) -- empty choice display
as sel
from dual
which results in a html source of:
<tr><td class="table-work-overview-firstrow">SEL</td></tr>
<tr><td class="table-people-overview-white"><select name="f10" class="search-table-input-long" ><option value="0">...<option value="7059909" >1mbit/s<option value="7059910" >NAT DHCP pordi suunamine</select></td></tr>
and the other with a query of:
select NAME as DISPLAY_VALUE
, ID as RETURN_VALUE
from OBJ_TPL_SELECT_OPTION
resulting in following html source:
<tr><td class="table-work-overview-firstrow">DISPLAY_VALUE</td><td class="table-work-overview-firstrow">RETURN_VALUE</td></tr>
<tr><td class="table-people-overview-white">1mbit/s</td>
<td class="table-people-overview-white">7059909</td>
</tr><tr><td class="table-people-overview-white">NAT, DHCP, pordi suunamine</td>
<td class="table-people-overview-white">7059910</td>
</tr>
Where should I look for the reason of no commas in the first result?
Confused,
Kaja

Htmldb_item.select_list_from_query-report error: ORA-01722: invalid number

Hi, i am trying to create a tabular form

my application is:

Any Help?
Thans in advance
Costantino

When your inner SELECT statement is firing it is doing a type conversion. It is seeing a number value in 'ac6lis.ACLIS_TSG_ID' and trying to do a number comparison with 've1edz.EDZ_TSG_ID'. 've1edz.EDZ_TSG_ID' has a non-numeric value in one of the rows which results in your error. To correct this place quotes around the value of 'ac6lis.ACLIS_TSG_ID' like:
select ACLIS_TSG_ID,
htmldb_item.select_list_from_query(2,ACLIS_EDZ_ID,'select EDZ_DESCRIZ, EDZ_ID from ve1edz where ve1edz.EDZ_TSG_ID ='''||ac6lis.ACLIS_TSG_ID||'''') edz_select_list

Help with Multiselect List Item

Assuming one employee can work for multiple departments, I want to display the departments employee 7844 works for preselected in a multiselect list.
I am using the following query statement in a report region.
select htmldb_item.select_list_from_query_xl(1, deptno ,'select DEPTNO,DNAME from scott.dept ','MULTIPLE HEIGHT=25', 'Y',null,null,null,'Department',null) a from scott.emp where empno = 7844
The result I am seeing is a multiple multiselect lists with one department selected in each list.
How should I modify the query to get what I want?
Thanks

Hi Carlos,
I set up a test case in exactly the same way and it worked fine for me. I created a page item called P1_DA_DEMO and added some static select list values then added some help text.

HTMLDB_ITEM.TEXT : disable item !

Hello,
I have a question regarding the use of HTMLDB_ITEM.TEXT,
Exemple, if my report contains the following :
select
HTMLDB_ITEM.HIDDEN(1,p.id) id,
HTMLDB_ITEM.TEXT(2,p.year) year,
HTMLDB_ITEM.TEXT(3,p.name) name
FROM person p
where p.id = :P1_ID
- the column year is diplayed but I have to disable it.
- the column name is updated by the user.
the save process is the following :
for i in 1..wwv_flow.g_f01.count loop
if wwv_flow.g_f01(i) is not null then
update person set name = wwv_flow.g_f03(i)
where id=:P1_ID and year = wwv_flow.g_f02(i) ;
end if;
end loop;
works fine.
My problem is : I must disable the column year, I have do the following :
select
HTMLDB_ITEM.HIDDEN(1,p.id) id,
HTMLDB_ITEM.TEXT(2,p.year,3 ,2, 'DISABLED=DISABLED') year,
HTMLDB_ITEM.TEXT(3,p.name) name
FROM person p
where p.id = :P1_ID
Now, wwv_flow.g_f02(i) is no longuer recognized !!!!!!
Any help !

How to validate htmldb_item form item

I have a multiple row form item using htmldb_item.text ( so that a user can enter a quantity for that row item ).
How is validation best handled to ensure that a value is entered for that row?
note: there is also a htmldb_item.checkbox on the row that the user checks to flag that an operation should be done.
Thanks as usual
Bill

for what this is worth:
as scott said, only checked values are passed through from htmldb_item.checkbox'es over to the htmldb_application.g_fNN arrays. that's just how conventional web checkboxes work. if you want to keep your checkboxes in your form, just do their processing in a separate loop. if you're having a hard time keeping the values of your checkbox array matched up with the other htmldb_item values from their corresponding rows, just make sure your checkboxes return values you can use to identify your checked rows. so if you were going against the emp table, i'd suggest having your checked values return EMPNO's...
select htmldb_item.checkbox(1,empno) c from emp
...that way you could more easily match those empno's up with your other htmldb_application.g_fNN values during your page processing.
hope this helps,
raj
