Hiding Null columns in report

Is it possible to hide a column is the entire column is null, but to show it where there's value in it? I was wondering if this can be done automatically in report, thanks!
Helen

How would one go about conditionally showing a column in the rows section of a pivot table if all values or null?

Hiding a column in report

HI Apex Community
I want to hide a column in a report based on an item(#item#) of the same report .
for ex , if invoice is zero then hide DUE row of that particular client
I tried with condition value is null equal to #invoice# but it hide the whole column instead of individual column.
Pls suggest me how to implement this .
apex 4.1.1 oracle 11gR2 , oc4j , linux.
thank you

I've tried this sort of thing before - so you want to add a link if data is present?
yes when data is present then only show the link else hide link/image
Under region attributes, make sure you clear "show null as", and define your link target as normal.
Yes it is blank.
Alternatively, you can construct the entire link within your SQL, using the NVL2
Tried with NVL2 , decode case
it works until ,i assign an image to it .
i dont know where im doing wrong , since i used the same code as i did in apex 4.2 at apex.oracle.com

Hiding empty columns in report builder

Hi,
This is my first adventure with report builder and I have
managed to produce some custom labels which work almost perfectly.
I say almost because there is one thing I can't seem to do.
I have a label for addresses. The address data consists of
data from a query including, name,
address1,address2,address3,town,county,postcode.
Some of these are quite often empty but the label still
displays a line break and the ',' at the end so I might end up
with:
Dave Phipps
27 Acacia Road,
MyTown,
MT1 4JP
In the above address the fields address2, address3 and county
are empty.
How do I set this up in Report Builder to hide the missing
lines so that I would end up with:
Dave Phipps
27 Acacia Road,
MyTown,
MT1 4JP
Any ideas?
Cheers,
Dave

Interactive Report with Null Columns

I've got a user who wants to export an interactive report, and he needs certain columns to appear on the export for him to fill the data in later (this is an intermediate step, while we work on getting all the data he needs in to the database). I've created the report query, and there are a handful of null/empty columns (to preserve the correct order for the export). When I try to add this query to APEX in an interactive report, I get a "ORA-00001: unique constraint (APEX_040000.WWV_FLOW_WORKSHEET_COLUMNS_UK2) violated" error.
Googling around shows me that this happens because of similarly-named columns, and the solution is to provide aliases to all columns. My report has aliases on all columns, but I still cannot create an interactive report. I've tried changing the null columns to empty strings, as well as enclosing the aliases in double-quotes, but nothing works. I can however use my original query to create a standard report, but due to the export requirement, this isn't ideal.
I was able to create the interactive report with one null column, and then edited the report source to add in the others. This had to be done one at a time, since trying to add multiple null columns at the same time gives the same error again. Unfortunately, when I try and run the page, I get an "ORA-20001: get_dbms_sql_cursor error ORA-00918: column ambiguously defined" error.
My original query:
select customer.customer_name as customer,
       project.name as project_name,
       trunc(project.estimated_end_dt) as due_date,
       project_status.project_status_desc as status,
       null as revenue,
       project.baseline_effort as baseline_hours,
       null as projected_cost,
       null as est_gain_loss,
       project.actual_hours as actual_hours,
       project.estimated_hours as projected_hours,
       null as projected_cost,
       null as projected_gain_loss,
       null as roi
    from project,
         customer
where customer.customer_id = project.customer_id
and project.inactive_ind = 0
and project.customer_id is not null
and project.estimated_end_dt >= :DTP_P50_STARTDT
and project.estimated_end_dt <= :DTP_P50_ENDDT
order by customer.customer_name,
         project.estimated_end_dt;             Can someone tell me a way to create an interactive report with multiple null columns?

Hi shimmoril,
The problem is likely that you have two columns aliased as "projected_cost" (7th column and 11th column).
Hope this helps,
John

I want to hide a column in report 6i

hi
I want to hide a column in report 6i,
I used this code
function F_col_qty3FormatTrigger return boolean is
begin
if :color3 is null then
return (false);
else
return (TRUE);
end if;
end;
plz note that COL_QTY3 and COLOR3 both are from different table
and resulting gave this error
REP-1314 Format trigger 'F_col_qty3' reference column 'color3' at wrong frequency.

You can format fields from a lower level group using fields from an upper level field, but not vice versa. This is because for the same upper level field there may exist several values of the lower level field. If this can not happen in your situation, there is no reason to place the fields in different groups.

Changing the Column Header and Hiding the Column dynamically???

Hi friends..
I'm new to OBIEE field. I'm working in a OBIEE project that requires to dynamically change the column header, and dynamically hide the column depending on the prompt value.
I know we can dynamically change the table header using the presentation variable but I couldn't do that same thing with column header.
I searched some forums that suggest to use java script for this purpose but I'm not able to do the same also. If anyone had same issue before please help.

toony, I'm not sure it's possible to do all that you want exactly the way you want, but here are some ideas you can pursue.
To dynamically change column headers without javascript, check this blog out...
http://oraclebizint.wordpress.com/2008/01/25/oracle-bi-ee-101332-dynamic-column-headers-using-presentation-variables-sets-and-conditional-formatting/
As far as dynamically hiding a column, I don't think you can do this, but since you don't provide any details on how the PV is supposed to hide a column based on the value, are you talking about hiding a column for one PV value and another (different) column for a different PV value? Or are you talking about hiding one column when a PV has certain values and displaying it when the PV has a different set of values?
I have managed to create both scenarios via a work-around, but the procedures require some writing so I don't want to put both. Please detail how you want your PV to "hide" a column or columns.
P.S. I don't think column selectors will do the trick for you. Basically column selectors work like this: Say you have a report using Sales Region ID, Region Name, and Sales. Now let's say you want the user to choose if he/she wants to see annual sales, or quarter sales or weekly sales, etc. The column selector view would allow you to put the various columns (Year Sales, Quarter Sales, Weekly Sales) as an option the user can select. Once selected, the sales figure will change for the time period selected. For an example of how this is done, check out the section in this "Oracle by Example" link.
Waited too long to publish this... Madan beat me to it, so there is some overlap here...

ORA-24347: Warning of a NULL column in an aggregate function

The following query works fine, normally.
select max(ship_date) Ship_date,msn.attribute7 from
     mtl_serial_numbers msn,
     mtl_item_categories mic,
     mtl_categories mc
               where      msn.inventory_item_id = mic.inventory_item_id and
               mic.category_id=mc.category_id and
               mic.category_set_id=1 and
          mc.segment1 in ('ILMI','ILM','ILMI-UNT')
          Group by msn.attribute7
But when I include the same query inside a SQL report it gives me the Following error message
ORA-24347: Warning of a NULL column in an aggregate function
Help me out.

I tried out with some Dummy Date, it worked fine.
But the problem I am facing here is I cannot assume
any Date for the corresponding column. Whether there
is any other possibility to avoid this problem without
giving any dummy date?

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?

Updating a JTable by hiding/displaying columns

I have a customizable JTable where I display/hide columns according to a users' selection criteria. My code works fine for hiding/displaying columns if the Jtable is opened for the fist time, but doesnot work if I want to hide columns in already displayed table.How do I do it?? Any clue?? I tried
myTabModel.fireTableDataChanged();
but this only works for updating the table data...it does not hide columns for me... when I hide column I just remove desired column like this:
myTable.removeColumn(myTable.getColumn("Column 3"));

Here is the sample code I tried. It worked without any invalidate or repaint or updateUI(). generated using NetBeans

% behaves like NULL at Disco Report ?

Hi,
I try to use '%' at parameter , but disco report comments it NULL and retrieveing no record..
I create parameter at condition for it...
Discoverer version is 4.1.41.05.00
What should i do to accomplish it?
Thanks...
Defne

Hi.
When I run a report with '%' parameters and the report does not return any rows, I check the parameter list and finds that '%' is replaced with NULL's.
I've checked the NLS_LANG parameters in the registry and compared them to the PC's on which the reports don't work, and they use the same settings, so I don't think the problem is language settings.
I have found a workaround though. If I use the following in the conditions part:
NVL(Column,'$') LIKE NVL(:Column Parameter, Column), I get correct results even if my '%' parameters are replaced by NULL.
This evaluates null columns to $ and the parameter to the result of this evaluation (sorry for bad explanation) and makes the condition true -> the row is displayed.
Comments are welcomed :)

note: BPEL keeps it's own "offline" copy of table and database items. A column that is marked not null in the database can be marked as nullable in this area. (if you kmow that a trigger is going to cater for this ..)
One workaround is to use a trigger to provide value rather than use the column default ..

ORA-01400 - not null column with default value and item with authorization

I've searched - I would think someone has run into this. APEX 3.0.0.00.20 - I've created a simple form on a table. One of the column is a not null column with a default value. I have a select list on that item, but it has security on it - authorization scheme. So, it checks the user and if that user isn't of the right role, it will not even display that item. However, APEX appears to still send in the column in its sql! So, the default value is useless, it sends in null each time. Even if I set the default at the Item level, I get null. Argg. That's got to be a bug...
In debug, I do not see the item listed at all. It's not used. That's fine - but why is it trying to insert the value? I would think it would leave it off??? I think because the item is associated with a database column. But, getting around this is ugly. Having to create a hidden item for each one, and then check to see if I need to take the list value... horrible. Any way to get around this???

I should add - I guess I can always put my own custom process in to replace the DML. Just seems like a simple thing - if the value doesn't appear on the debug, isn't set with any default value... don't include it in the DML.

Can we add a new column in report which is not in table.

Hi All,
Can we create a new column in report which is not in table.
I have two columns in my table completion_date, manufacture_date. If the difference between the completion_date and manufacture_date is 0, -1, 1 then the new column of the report will say on time against each record or else will display late. Any suggestion how to proceed on this
Regards
Edited by: User_Apex on May 16, 2011 5:54 AM

Standard report then, NOT an interactive report (which if you were using, you could build a computation and report on that)..
Then the adding a column in the query would be your best best...

How to use the procedure column in reports

Hi all
How to call the procedure in reports as source.. If possible how to use columns of procedure in the layout column of report????

Hi,
Your query is not clear.
1. In subject are you asking total column.
A. Edit pivot view and go to Rows and click Total BY option here you can find option like (none,before,after) the you can select after it will display total all culms.
2. I want use the columnC in columnD ? -- Am not understand.
A. What my understand is you want to see the report only C and D values only.
If it is correct we can apply filter in report level click column filed and apply not equal to A then it will show only C and D only.
If it is wrong pleas post me correct one with example. Will try to help out this.
I am not sure this is what your looking so far.
Award points it is useful.
Thanks,
