Conditionally display button in a report

Is there a way to conditionally display (or disable) an edit button that is displayed on each row of a classic report in version 3.2 ?
ie. lets say an orderShipped field exists. If the orderShipped is null (not yet shipped), that row will display (enable) the edit button. If orderShipped exists and the date is displayed, the order button is hidden (or disabled).

Hi,
there are probably many ways to do this so this is just one.
Write a report query something like this:
SELECT id,
name,
CASE
WHEN order_shipped IS NULL THEN
'<a href="f?p='||:APP_ID||':'||10||':'||:APP_SESSION||':::::P10_ID:'||id||'"><img src="edit.gif"/></a>'
ELSE
'OK'
END AS edit_col
FROM orders;
Change according to your requirements.

Conditional display in a SQL-Report/Report Region

Hi,
here I have an example for "Conditional display in a SQL-Report/Report Region". I figured it out in Firefox 3.6.2 using Firebug as development tool on Apex 3.2.1.00.12.
First you have to put the following javascript code in the Page HTML-Header:
<script type="text/javascript">

</script>
Maybe you have to modify the "vd_getBody" function. I'm searching the table cell with having the class "t10data". When you use another theme, there's maybe another class used.
Second is, that you set an static id for your report region. I prefer this structure:
R<app-id><page-id><seq> (Raaaaappppsss) e.g. R094260001010.
First example is to turn off the onMouse-Effect. Maybe on the first or last column definition you put this code in the "HTML-Expression" area:
<script>ex_conditional_tr('R094260001010', #ROWNUM#);</script>#ID#This will call the example function ex_conditional_tr with the parameter
a) the region id
b) the rownum (as oracle always starts with 1 this is the first data row [rownum=0 is the table header row])
Second example is the conditional formatting of a table cell. Put this in the HML-Expression area:
<script>ex_conditional_td('R094260001010', #ROWNUM#, #COLNUM#-1);</script>#ENAME#This will call the example function ex_conditional_tr with the parameter
a) the region id
b) the rownum
c) the cellnum (here we have to subtract 1 to get the "real" cell index)
The "ex_conditional" functions are just a representation of how to get the row or cell node.
Hope this help a bit.

I would use a CASE statement in the select....
each CASE would be an img src tag for a different button if the button is an image.
does that make sense? I can include an example if you would like...

Conditionally display button based on number of rows in rpt query results?

I know that I can conditionally display a button based on the number of rows returned in a query entered in the condition. However, I have a report region button that I only want to display if any data was returned by a report query. Since I've already executed the query to generate the report, I do not want to execute it again to determine whether any rows were returned. Is there any way to detect whether any rows were returned for a report other than to reissue the query?

http://htmldb.oracle.com/pls/otn/f?p=24317:52
OK, so it looks like it contains the rowcount of the report region rendered just before the variable (apex_application.g_flow_total_row_count) is referenced.
Sort of like how SQL%ROWCOUNT contains the no. of records affected by the last SQL DML statement.
Note that the pagination scheme affects the result. In the example above, the 2nd report region is showing 10 rows with a 'Rows X to Y' pagination scheme. So g_flow_total_row_count=11 because I guess the reporting engine has to fetch the 11th row (and discard it) to determine whether to render the 'Next' pagination link.
If you select a pagination scheme that forces the reporting engine to fetch all the rows 'Rows X to Y of Z', g_flow_total_row_count will always be Z, not the number of rows actually rendered on the screen.
Thanks

Conditionally displayed columns of interactive report not displayed

We have an interactive report in which few of the columns have been defined with conditions for display.
But on the interactive report page, when the conditions are satisfied these columns do not display in the report by default.
These columns are found in the 'Select Columns' -> 'do not display' pane. Everytime the report is run, these columns need to be selected using the select column.
Is there anyway to make the columns appear in the report by default, when conditions are true.

Thanks Jari for your help.
For this issue, we finally came up with a work around.
we removed the conditions from all the columns then ran the application report page.
Clicked on Select Columns and moved the columns from the do not display pane to the right pane.
Ordered them as needed. Then saved the report as primary.
Then again went to the edit page-> interactive report and applied the conditions to the necessary columns.
and it worked.
When I went to the report these columns are displayed by default.

Conditional Display on multiple items?

Is it possible to use multiple items in the conditional display region of a report? For example I'm trying to use the
"Value of Item in Expression 1= Expression 2" and when I populate 1 item with the value in expression 2 it works just great but if I try to place 2 items that would both equal expression 2 it does not work.
I've tried
Expression 1:
P14_ITEM1, P14_ITEM2
Expression 2:
10
Is this possible? And if so is there different syntax I should using in Expression 1 to identify my items?
Thanks,
Zala

I have done something similar but I used the exists statements and write a SQL "SELECT 1 FROM dual WHERE :x1 = :x2".
Cheers Mike

Conditional display of report

hi
i have a batch table (batch_id,batch_name,batch_type..)
i have to pass batch_name and batch_type as a parameter so i have 2 item on a page
batch_name :-select list
batch_type :-select list with submit and it values select from the values of batch_name
create button :- when i hit the create buttons it will show me 2 report in the same page based on the latest batch_id
so i have to apply conditional display on the reports
what would be the condition for the conditional display so that i will get to reports in the same page
dependency between report is batch_id

Hi Tobias,
i have interactive report.
the content of report is displayed based on the input values(from select lists),
1)select list -p_cust
2)select list-p_switch(the values of the list select from the values of p_cust i.e select d r from switch_t where cust_name=:p_cust)
requirement like this
1)First i have to select a customer
2)when i select a values (switch) from the switch select list -the result of the report for a paticular switch .
e;g-p_cust='ABC' and p_switch='XYX'
the output of the report would be the all records for 'ABC' customer for a Paticular Switch that is-'XYZ'
3) again when i select a value "All_switches" from the switch select list it should returns all the records for all switches

Conditional Display of Interactive Report Based on Field Above

Page one has simple text box entry for a Vendor # with a button that branches to a page displaying information for that vendor. In a region below, I would like an interactive report that displays all of the item and description that vendor provides to our company. I have tried to use the Conditional Display to disply only items in the report but have been unsuccessful. Your help is appreciated!
Thanks.

Hello user2961006 (please tell us your name),
I understand your question to be, "how do I make a report on page two only show rows related to an item entered on page one". Putting a condition on a region isn't the answer here - you want the report to always display, but just with different rows depending on the vendor number entered. A condition on a region is used to either display the region or not.
What you need to do is put a WHERE clause on the SELECT statement that your report is using to get its data. For example, if the item holding the entered vendor number is P1_VENDOR_NUM, the SELECT statement for your report would look something like:
SELECT item, description
FROM my_items
WHERE vendor_num = :P1_VENDOR_NUMNote my_items is a fictitious name. This will tell the DB to only retrieve rows where the vendor number is the vendor number entered by the user.
Hope this helps, I'll gladly accept reward points if it does ;-)

Conditional display of list box in form (depends on other report column)

Hello,
i have one question regarding conditional display in forms.
I have a tabular form where only one column ("flag") is updateable, all other columns are visible only.
I changed the column "flag" from "standard report column" to "Select list (static lov)", which has the values "yes" and "no".
This works fine. But in the running form i want to display the list box only if the column "status" = 'ERROR'.
The column "status" can have the values 'ERROR' and 'OK'.
When one record has "status" = 'OK', the column "flag" should not display the list box (only empty column row),
when one record has "status" = 'ERROR" the column "flag" should display the list box.
The idea behind is that if a record has "status" = 'ERROR' i have the possibility to confirm that "error" and update the column "flag" with "YES". This should only be possible for errors.
This is my main problem.
I tried with conditional display, but this hides or shows the column for the whole report/form, not on record level...
The second problem then is, that if the column "flag" is changed to "YES" in case of column "status" = 'ERROR', then it should not be possible to change it again to 'NO". At the beginning it is 'NO', but once changed to 'YES' it should not be changeable any more.
Is this possible?
Thank you in advance,
Matthias

Hello Mike
your solution sounds good, but unfortunately it is not working.
None of my 2 columns are displayed, although i tried it as you wrote and the conditions should match...
But i am no sure if this can work. If so, the 2 columns must fuse to 1 column:
ID STATUS FLAG
1 ERROR yes/no => comes from column1
2 OK (null => comes from column2
so "FLAG" must display column1 and column2 in one column. is that possible?
regards,
Matthias

Conditional display of a column link in sql updateable report

Hi There,
I've attempted to look thru the Apex forum about using an Authorization Scheme in an SQL Query (Updateble Report) where I can conditionaly enable (display) a column link based upon a value in the report but alas I cannot find a solution.
What I have is a SQL Query (updateable report). What I want to achieve is dependant on the value of one of the columns in the report query conditionaly display a column link for the row being displayed. For example if the report dispayed the data from emp, dept only display a column link for rows where the deptno = 100 otherwise don't display the column link. Is this possible to achieve?
I've tried to define in the authorizatuon scheme in the where clause of an SQL Statement to reference the report column as #deptno# but this doesn't work.
TIA

Boketi,
I was unsuccessful yesterday in demoing what I believe you want to achieve. It appears that an authorization scheme will not process row by row within a standard report so as to allow a conditional display of a link or any other column attribute. You can conditionally display a column by the use of a page item but this method appears to be all or nothing.
I was successful when I coded the return of the empno via a Case statement but the Link still appeared even though there was no value (empno) to link with. So essence the link to you to a blank for with no PK to read the database by.
SELECT CASE WHEN deptno = 10 THEN empno ELSE NULL END empno,
       ename,
       job,
       hiredate,
       sal,
       comm,
       deptno,
       phone_nbr
FROM   empJeff

Conditional display column in report

Hi,
If we have a single row report of 30 columns, and I want to display only the one with any values but null and hide the null ones, Is there a way to do it?
It's the same issue discussed in this thread conditional display column in report
thanks,
Fadi.

Samara - I suspect there are a few ways to do this, but none obvious or very easy as far as I can see.
You can create dynamic SQL (as Arie and others have suggested) to only include the columns that are not null.
You can build and output the HTML directly to the page, choosing only to include the values that are not null.
You can create a set of conditions that you can apply to the report columns. A very crude example might be 30 hidden page items like 'SHOW_COL1' etc. (not great, I know), or perhaps you could set a hidden page item to a value like '01:02:03:'etc., with the number only being included if the value is not null (so that col3 being null gives you '01:02::04'etc.), so that the condition for each column is 'Text in expr 1 in contained in Item in expr 2', where expr 1 is '01' for column 1 etc.
Sorry, that is a very contrived example, but it's just to illustrate that there's generally a way of doing pretty much anything in APEX. You might create your item containing the comparison expression by requerying the data in this kind of way:
SELECT NVL2(column1, '01', '') || ':' || NVL2(column2, '02', '') || ':' etc.
FROM table
WHERE condition
However, wanting to create a single-row report with nulls hidden makes we wonder what you're actually trying to achieve and whether there's a better way? Could you use a series of page items, for example?
John.

Complex conditional display in report table

Hi,
I built a report in a region, and want to make one of the columns conditionally display based on attributes from two other columns in the table. The drop-down for the conditional display only lets me refer to the current item. Is there a way I can reference the other cells in that table row in a PL/SQL expression (e.g.: something akin to #COLB# is not null and #COLC#>1000 ?)
Related question: I'm assuming the reason I can't directly change the source for the report region and can only modify it from the Query Definition tab is because I used a wizard to create it. Is there a way to "undo" this and make the source for the report fully editable? That would also solve the problem, since I could just add a function-derived column to the query.
Thanks in advance,
Keith

One final update and rephrasing of the problem, because maybe there's another way to solve this.
I have a column in a report that links to another page, but the link is only shown if a certain condition is met (which is based on other cells in this table row). I can test for those conditions in my original SQL query, so that a null value in my link column results in no user-clickable link being created. (I have to make sure that a null value appears as null on the report page, too.)
This works fine if the link text is just that: text. Because not meeting the condition returns null, so no text == no link.
Now the only problem I have comes if I want to use an icon (e.g.: the edit icon) instead of link text.
What I really want is for the icon to only appear if a certain condition is met. However, the icon replaces the column value so I can no longer use a null value to prevent the link from appearing.
The original question asked whether I can use other report cells (#foo#) in the conditional display for a cell. If that's not possible, any suggestions on how to achieve the desired effect without resorting to JavaScript?
Thanks.

Conditionally displaying different images in a report

Hello. I have a simple report. In one column of it I have a link to another report. Instead of showing the value for the column, I show an image using the column's Column Link's Link Text property.
In the Link Text field, I put an <img src="#WORKSPACE_IMAGES#my_image.jpg"> tag.
Works like a charm - on the report the column displays little icon images that can be clicked on that take the user to a different page.
I would like to conditionally (based on the actual value of the column's row) display two different images. Think of a green Up arrow vs. a red Down arrow.
How can I do that?
Or can I at least have the image above conditionally display and if the condition is not met, not display anything?
I notice each of the report's column's attribute page has the Conditional Display section. How does work for a column?
Thanks
Boris

Use a case expression in the query, e.g.
case
when x <= 50 then 'down.png'
else 'up.png'
end icon
...and change the Link Text field to
<img src="#WORKSPACE_IMAGES##ICON#" alt=""/>

Conditional display of "Custom" Buttons in Portal Forms

Could someone tell me if the following is possible, and briefly explain the steps to a beginner in Portal (but reasonably familiar with PL/SQL):
Problem - How to display "Custom Buttons" conditionally
Example -
a) Assume you have a certain record ("patient_address"). The hospital requires that every patient address be authorized before submitting records to health insurance. However, authorized records should not be authorized again.
b) Also assume that the "patient_address" table has a column "authorized" (which can contain Y or N)
* The requirement is to show an "Authorize" button whenever the record being viewed has the "authorized" column as "N" only
* If possible, this can be further improved by obtaining whether the person viewing the information has permission to authorize, but this can be taken as a next step
Approaches -
1. If possible, achieve this in Portal Forms
2. (worst case) - show the button, but show a message if it is pressed and the action does not apply
Somehow, it seems as though Portal Forms is not suitable (or does not have the documentation readily accessible) of how to do specific, custom, real world forms design as in this example - could someone please elaborate
Also, would this be better done by using one of the following in combination with Portal:
- HTT (will this be supported, given that it is an Oracle internal technology)
- PHP (is this even compatible with Portal?)
null

Hi,
Conditional display/hide of custom buttons is not yet supported in Portal.
However, if you are willing to modify the generated form package this could be done.
Each form has a procedure called row_function which conditionally hides Insert/Update buttons depending on the mode. By default all elements of a form are visible, then row_function modifies the "visibility" property to hide that element.
for example, this is a fragment of row_function code which hides the Insert button in update mode:
"_form_state" := p_session.get_value_as_varchar2(
p_block_name => "_block",
p_attribute_name => '_FORM_STATE');
if "_form_state" = 'UPDATE_AND_DELETE' then
"_idx" := get_index('INSERT_TOP');
p_form.items("_idx").visible := 'N';
end if;
You can add any additional code to check form's session storage/custom package variable/function whatever is more suitable in your case.
Then you just set visible to 'N'.
"_idx" := get_index('MY_CUSTOM_BUTTON');
p_form.items("_idx").visible := 'N';
Of course the biggest drawback of this is every time you edit your form you will loose your change and must edit the package manually. To minimize the effect you can create a custom package/procedure with type signature matching that of row_function and place your code there, so you will need to add only one line of code to the row_function.
Hope this will help to resolve the problem, I don't know the status/plans for HTT/PHP support in Portal.
Thanks,
Dmitry
