Conditional Display on APEX region
Hello,
I need to validate following condition
Value of Item in Expression 1 = Expression 2
In above mentioned condition, I need to evaluate two different hidden item. P1_X and P2_X.
For e.g. when P1_X = 0 and P2_X = 1
How can I accommodate above two items under same conditions for the same region?
I tried putting comma but seems it does not work.
For e.g.
Expression 1
P1_X, P2_X
Expression 2
0, 1
What is the correct way?
Thanks,
R
Hi,
You can use SQL exists condition and put the following query in expression 1
SELECT 1 FROM DUAL WHERE :P1_X = 0 AND :P2_X = 1Thanks,

Conditional Display of A region based on a Search condition
Hello All,
I would really appreciate any suggestion and pointers on how to achieve the below.
My requirement is to display a tabulated result based on a search condition.
I have two regions. One region contains the items to enable a search and the other region will be used to display the search results.
Region A is an HTML region containing three items
1. A text field: to enter the search text
2. A list field: to determine the type of entity to search (customer_id, invoice number, Passport No)
3. A button: to initiate the search process.
Region B is a reports region displaying the search results
My question is:
1. Is basing the source of the region as a “PL/SQL function returning a select statement” the ideal choice. I will have variable “WHERE” clauses based on the search criteria entered in region A. However, the columns returned will always be the same
2. How do we get the region B to display only when there are results returned from the search results
3. How do we base by result set based on a stored procedure in the database. Basically as an API. We pass in the parameters and the API passes the result set back to APEX. This way, I can have all the DML hidden behind the stored procedures
Looking forward to your comments and suggestions

Conditional display to the region
Hi, I need to show or hide a region depending on the value of an item in another region. I try with the condition "value of item in expression1 = expression2 " and in the box of expression1
:P29_ID
in the expression2
1
And nothing happens, the region disappears and never shows again.
Please, help me!Try using P29_ID in the field for expression 1 (without the colon).

How to use more than one region 'Conditional Display'
Hi,
I use a region and i want to use 2 Conditional Display for this region:
. Fisrt when 'Request Is Contained within Expression 1' ==> 'Val1,Val2'
. Second when 'Inline Validation Errors Displayed'
Is it possible.
ThanksHi,
The first one is relatively straightforward as there is a Condition Type available for that.
The second one is a bit more complicated but can still be done. Have a look at Re: how to use wwv_flow.g_inline_validation_error_cnt? This will tell you how many validations failed. If there were any failures, you can set a hidden page item to 1, for example, and then use this page item in your condition

How to handle Multiple Conditional Display
I have a page (call it page 2) that one can navigate to using a column link from another page, or using a link from a list. On page 2 I have a region that I would like to conditionally display; display the region if they navigate using the list link, do not display if they navigate using the column link or if the page is in printer friendly mode. I can probably handle a multiple conditional display for a region using something like a PL/SQL Function Body returning boolean, is it possible to know which link was clicked?
Other suggestions would be greatly appreciated.
Regards
MarkSudheshna-
In my List, I set REQUEST to P2_PARAM. On page 2, in the region where I want to control the display, for Conditional Type I chose PL/SQL Function Body returning boolean. In Expresion 1 I have this code;
BEGIN
IF V('REQUEST') = 'P2_PARAM' THEN
RETURN TRUE;
ELSE
RETURN FALSE;
END IF;
END;
The ELSE, handles the times I do not want to display the region, in my case if I linked to the page from a column on a page other than page 2, or if I want the page in printer friendly mode.

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.

Conditional display of region with PL/SQL function returning SQL query
Hello,
ApEx 2.0.
I use PL/SQL functions that return SQL queries to display the contents of a region.
How could I conditionally display such region ? If no data is found, the region shouldn't be shown. I tried with "SQL query returns at least one row" but this doesn't seem to work.
Thanks,
MatthiasHi Matthias,
Are the regions in question report regions? So your PL/SQL process is returning a SQL query and then populating a report?
The EXISTS(SQL Query returns at least one row) condition should work, try running the query you are using in the Expression 1 textarea inside SQL*Plus, or SQL developer using the same parameters, and see what gets returned.
If you are still stuck, can you post the query you are using inside your Expression 1 textarea of the Conditions section and I can take a look at it for you.
Hope this helps,

How to conditional display Report Region based on number of rows returned
I have a page with two Report Regions.
One Region should display if the Query returns 0-1000 rows. The other should display if the same Query returns more than 1000 rows.
The only way I can figure out how to do this is have ANOTHER query in the conditions field for each Region to Select count(*) from etc.
I know there is a #TOTAL_ROWS# value but that is only available after the Region is displayed. Is there some other built-in variable that can be used to put in the Conditions field or is doing duplicate SQL queries the only way?
Any help would be appreciated.Rather than running your query 4 times (by embedding it in your condition), you can have a region that is not displayed, with a hidden item, and set the value of the item in a before header computation to the count of your query. Now you can conditionally display based upon the value of that item.

Conditionally Displaying Regions w/o Submitting Page
I have a radiogroup with 6 choices in it. For each of these 6 choices exists a corresponding region, which I want to conditionally display upon choosing its corresponding choice in the radiogroup. The problem I'm having is that the only way I know how to do this is to make the radiogroup a radiogroup w/ submit, but I don't want to submit the entire page and its contents upon making a selection from the radiogroup, I just want to conditionally display specific regions and not submit the page until the submit button is clicked. It seems as though there should be an easy way to do this, is there?
That's actually the first thing I tried too. The only problem with that is that with just a redirect, the item doesn't seem to store the value of the choice from the radiogroup, so there's no criteria there by which to set the conditional display.

Condition Displaying the region
Hi All,
I have two regions in one page, when I click the one of the column(hyperlink) in the first region(interactive report), it displays the second region(Report) based on the condition.
My Condition is when the #status# = 'Pending' then only it should display the second region.
if #status# = 'Issued' it should not show the second region.
How can I achieve this, can anyone suggest how to satisfy this condition.
Thanks,

Data not submitting when I have a conditional display on a date field
Hello all,
Could someone please help me with the following issue?
I have created an updateable report region with four updateable fields. 3 of the fields store a number values and the fourth stores a date value.
Each updateable report item has a conditional display, and whether they are displayed or not is controlled by the end user using a radio group (with submit). This provides the user with three options.
If I remove all conditional displays all data will commit to the database without any problems. If I apply the conditional display to the number fields only, again the data will commit as normal. However, as soon as I add a conditional display to the date field it all goes pair shaped. The data will then cease to commit, with no error message at all. Once I remove the conditional display normal service is resumed.
I'm certainly an APEX novice at the moment, so I wondered if anyone could shed some light on this.
Thanks in advance for your help
SteveStew,
Basically, I have edited each applicable report field column attributes, via the report attributes tab, and selected a conditional display 'Value of item in Expression 1 = Expression 2' for all of them.
In the same report region I have created a radiogoup with submit called p51_update_type, specifying three static return values; R, F and S
Condition e.g.
*"Expression 1"*
p51_update_type
*"Expression 2"*
S
All columns display as expected, and commits to the database are normal, that is until I apply a conditional display to the date field (which relates to a table column of type DATE in the database).
Thanks

Solution: Combining Multiple Conditional Displays Types
Hi there,
I am hoping that you will be able to assist me with a Conditional Display issue I'm encountering. I am using APEX 3.0.1.
I have two regions on a page.
Region 1 (HTML) merely contains Items and a Submit button.
Region 2 (Reports) displays the output of a SQL query that includes the conditions based on the values in the Items (Dates To and From + Supplier from Select List).
The Items have item level validation for NOT NULL and VALID DATE but when I enter an invalid date the Report displays an error message with the fact that there is an erroneous Item.
I would like to utilise the No Inline Validation Errors Displayed seeded conditional but also include another condition where another Item > 0 (zero).
I was hoping to use the PL/SQL Expression or PL/SQL Function Body Returning a Boolean types but need help with the syntax for defining the No Inline Validation Errors Displayed seeded condition in PL/SQL.
Many thanks,
Gary

Dynamically hide/display multiple report regions.
Hi,
I need to build a dashboard like homepage for users with multiple report regions. Users should be able to pick the regions they want and the display point for those regions.
Is this possible?
Thanks in advanceHello Asha,
I think the "where" part would have to come from CSS. If you visit http://apex.oracle.com/pls/otn/f?p=49882:3653 you can see a couple of HTML type regions which I placed using div tags and putting something like<div class="rpt_query" id="rpt_query">in the region Header and </div> in the region footer. You can accomplish the same with Report type regions and maybe any type of region.
As for whether or not a region is shown, that can be done in the Conditional Display attributes. I do this by selecting "Value of Item in Expression 1 = Expression 2" as the Condition Type, a hidden page item as Expression 1, and a number (perhaps corresponding to check box as mentioned previously) as Expression 2. I'm actually using pseudo tabs and when a user clicks one of the tabs it changes the value of the hidden page item and submits the page to get the new region to show up.
Hope this helps,

Conditional display based on row count
I have a report region with sql query (PL/SQL function body returning sql query). In this region i have text item above the report. I would like to have a condition on this item that it should only show if there exists records in the report (row count > 0).
How can this be done?

Hi All,
I am new to Apex and I have searched here for my scenario.
I am using interactive reports region. My query is like this
select name , nvl(amount,0) from projects;
I am using nvl since I am using charts and otherwise chart wont work.
Now in the report we dont want 0 to be appeared and instead we want it to be null.
Could we use conditional display or we need a javascript ?
Thank you
Rajehs AlexHello,
For me a chart in an Interactive Report is working with null values?
I tried with SELECT ename, sal FROM emp
Does the above select also work for you?
