To display the column value though it is null

Hi all,
lineItems.ShipToCustomer.VName is having null in this case
When I execute this query I get zero records returned,the problem lies in lineItems.ShipToCustomer.VName :
select lineItems.ShipToCustomer.VName,C.VDealNumber CPRNumber, W.created SubmitDate, lineItems.VLineID LineItemNumber,lineItems.VProduct.Description Product from com.eastman.pricing.CprForm C,com.vendavo.platform.workflow.VWorkflow W where C.objectId=W.VWorkflowEntity.objectId and VID = 'CPR-013005'
When I execute after removing lineItems.ShipToCustomer.VName then the query returns one record:
select C.VDealNumber CPRNumber, W.created SubmitDate, lineItems.VLineID LineItemNumber,lineItems.VProduct.Description Product from com.eastman.pricing.CprForm C,com.vendavo.platform.workflow.VWorkflow W where C.objectId=W.VWorkflowEntity.objectId and VID = 'CPR-013005'
One more observation is when I include the column as lineItems.ShipToCustomer i.e after omitting only vname then I get one record returned.ShipToCustomer is a vector field.Anything to do with vector.
How do I get one row returned even though the lineItems.ShipToCustomer.VName is included in the query?
Thanks in advance

This query is specific to the project i'm working it is called VQL which mostly follows the SQL standards that is why i'm not able to use nvl() which is not implemented in VQL....
The problem which i'm facing i have explained below:

Displaying the column values of a wizard-generated form

Hello,
I created a Master-Detail page following the examples in the various Apex guides. The form is not working correctly, unfortunately. When I click the Add Row button a row is added at the bottom of the table. Once I enter data into that row and click the Apply Changes button I get an SQL Insert error. I understand error message; a hidden column is not getting populated. Having said all that, that is not my problem.
My problem is understanding how APEX is storing the data it displays in the table so I can manipulate it to place a value into that hidden column.
I read many posts about how data is stored in the fxx arrays. I've looked at my source and have seen values like f02, f03, f03_0004 and so on. So, I tried creating a report to display the contents of APEX_APPLICATION.G_F03(1). I created another report on the same page with the following SQL statement:
SELECT 'Code: '||apex_application.g_f03(1) F1
FROM DUAL;
When I run the page, the second report shows this: ORA-06553: PLS-221: 'G_F03' is not a procedure or is undefined.
Someone (I think Denes) suggest creating a process with the following PL/SQL to help locate the correct array:
BEGIN
wwv_flow.debug('******************************');
wwv_flow.debug('*** STARTING MY DEBUG HERE ***');
wwv_flow.debug('1: ' || APEX_APPLICATION.G_F01(1));
wwv_flow.debug('2: ' || APEX_APPLICATION.G_F02(1));
wwv_flow.debug('3: ' || APEX_APPLICATION.G_F03(1));
wwv_flow.debug('4: ' || APEX_APPLICATION.G_F04(1));
wwv_flow.debug('5: ' || APEX_APPLICATION.G_F05(1));
wwv_flow.debug('*** ENDING MY DEBUG HERE ***');
wwv_flow.debug('******************************');
END;
With that process in place, whenever I run the page I get an error that says ORA-01403: no data found. When I comment out the five lines that reference APEX_APPLICATION.G_Fxx the page runs, but I cannot see the remaining debug comments UNLESS I place the process to run before or after the Footer.
I hope that all makes sense.
So, what am I doing wrong about displaying the contents of the array that is storing the table?
Respectfully,
Leon

You can't reference a package variable in a SQL statement like you do in:
SELECT 'Code: '||apex_application.g_f03(1) F1
FROM DUAL;
You can only reference it in a PL/SQL block (like you did in a Before/After Footer process). If you try to use the variables before they are instantiated you'll get the no-data-found error.

APEX 3.0 Displaying the URL link for a column value ( only when not null )

Consider the example :
I have the following table with a column that may have urls to documents
Row Column ( url_column )
1 http://xyx.com/doc/doc1.pdf
2 http://xyx.com/doc/doc2.pdf
3 (null)
How do i display the column so that a the link shows up only if a value exists.
Setting the URL to #URL_COLUMN# in the 'Column Attributes' screen creates a problem when the value is null ( for Row 3 in above eg.)
Thanks for your help

I would handle it in the query itself, something like
select x, y, z,
       decode(url_column, null, null,
                '<a href="'||url_column||'">'||
                 url_column||'</a>') as url_column
from wherever

How to get the column values from a BC4J View Table in UIXML?

I am using a default UiXML Application for Order Entry system with Orders & Order Lines & Customers. I have a uix file OrdersView1_View.uix which displays (no updateable columns) all the Orders. How do I get the column value of a selected row in a BC4J Table (example:OrdersId) when a Submit button is pressed using UIXML or Java Classes?
I appreciate any help on this.

Hi,
You need to use keyStamp, an example:
<bc4j table name="orders">
<bc4j:keyStamp>
<bc4j:rowKey name="key" />
</bc4j:keyStamp>
Furthermore, you can automatically send the selected row key using the go event handler, so in the handlers section you could send the key to an orderInfo page:
<event name="show">

<ctrl:go name="orderInfo" redirect="true">
<ctrl:property name="key">
<ctrl:selection name="orders" key="key" />
</ctrl:property>
</ctrl:go>
</event>

How to display the sort value in the selection screen in the report title

Dear All,
How to display the sort value in the selection screen in the report title? I have selected a value in the selection screen for sorting , but i need that values by which i have sorted with in the report title. Can you please throw some light on this!!
Good day,
Thanks and regards
Arun S

Hi Arun,
Try this.
1, Set one dynamic parameter,
2, Drag and drop that parameter into your report title.
3, Pass the value(sort value) dynamically from your application,
4, Cheers..
Other wise Try with Dataset, create a dataset and fill thev alue into that.. Then set the data source from CR designer. and darg and drop that data column into the report.
Hope this will work,
Regards,
Salah

How to not display the column header in the table view?

I do not want to display the column header in the table view, how can I achieve it?

If you're using JavaFX 8 you can use the following in an external style sheet:
.table-view .column-header-background {
-fx-pref-height : 0 ;
If you're using JavaFX 2.2, the -fx-pref-height attribute is not available in css, so I think you have to resort to a lookup:
final Region tableHeader = (Region)table.lookup(".column-header-background");
tableHeader.setPrefHeight(0);
As always, I feel obliged to point out that I don't really like lookups. Sometimes they seem to be the only way, though.

Infopath display lookup column value

Hi
I have a Infopath 2010 form with which displays an employee record. Some of the columns are lookup from a sharepoint list.
How can I display the value of the lookup column instead of Id in the form.
The form has the main connection and the secondary connection for the lookup sharepoint lists.
The sharepoint lookup column is set to "Title" in additional column settings. Add a column to show each of the additional fields are all unchecked.
I searched google, but couldnt find an answer.
I tried to do the way described in http://sharepointsolutions.com/sharepoint-help/blog/2011/11/get-infopath-to-display-lookup-column-value-not-id/
But get error , since it works for repeated table.
Any Ideas?
Thanks
Venky

Hi Venky,
How did you create your look up column? Which column type is the column which your look up column looks for?
By my test, it is default behavior that the InfoPath form display the value of the lookup column.
Thanks,
Eric

To get the count of records and able to access the column value in a single

Hi
Is there any way to get the number of records in the query and access the column values
e.g
select count(*)
from
(SELECT department, COUNT(*) as "Number of employees"
FROM employees
WHERE salary > 25000
GROUP BY department ) a
This wil only get the Count, if i want to access each row from the inline view how can i do that.

Your question is not clear.
Are you looking for total record count as well as count by department ?
Something like this?
SQL>
SQL> with temp as
2 (
3 select 1 dept ,10000 sal from dual union
4 select 1 dept ,25100 sal from dual union
5 select 1 dept ,30000 sal from dual union
6 select 1 dept ,40000 sal from dual union
7 select 2 dept ,10000 sal from dual union
8 select 2 dept ,25100 sal from dual union
9 select 2 dept ,30000 sal from dual union
10 select 2 dept ,40000 sal from dual )

How can I get HyperTrend to display the numeric value output of a CHOOSE statement?

I have non-linear values I need to display on a HyperTrend graph. I'm currently converting the input raw signal to a Units (Engineering) value and then looking up the actual value (from a calibration chart) using a CHOOSE statement in order to display the actual value on a panel, but I need to display the values output by the CHOOSE statement on a HyperTrend graph, along with other similar values.
How can I do this?
