Number of Region Columns

Hi all,
I have to arrange my regions in 14columns...
but i am seeing that the maximum columns available as "9".....
is it possible to increase the number of columns.....
I also have a small issue in arranging my regions across columns....
sample application is at:
workspace: bi_development
UN and pwd: apexforum
appl : test
Thanks
you guys are really healpful.

Hi,
Firstly, you can't go higher than 9 columns. You would need to adjust the page template somehow to put two regions side-by-side and then use columns 1 to 9 in the first one and 1 to 5 in the second to get all 14 columns in. It may be possible with styling
For you 2x2 reports - you can do this by adding in a DIV tag around the report contents. In the region's Region Header add in something like:
<div style="height:100px;">and then close the DIV in the region's Region Footer:
</div>I have created a new page in your app that does this. But, here's another example doing the same thing (but using a height of 300px): [http://apex.oracle.com/pls/otn/f?p=267:28]

Report region columns constrained to 4000 chars? Hitting LOV problems.

Hi all,
I've hit a problem that I'm hoping will have a simple answer.
Quick overview of issue:
APEX 3.01 application running against a 10gR2 DB.
We have an LOV defined that works just fine on various forms but in report regions where the LOV is available via a drop down column value in the report region HTML table we are hitting the error:
report error:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
Some judicious debugging reveals that this seems to be because we are trying to load in more than 4000 characters into the LOV drop down in the report regions HTML table column (it's a moderately large LOV)..
This suggests that the default column type in a report region HTML table is VARCHAR2 and thus that there is a default 4000 character limit on any such column values, would that be a fair assumption? I know that the actual report row size always used to be limited to a total of 32k but this limit is a new one to me.
If there is such a limit, does anyone have any suggestions on how to work-around it i.e. is it possible to redefine report region column values to be other datatypes/dimensions or should we be looking at using an alternative such as a pop-up instead?
Many thanks.

Hi Scott,
Okay, what we have is a fairly simple Dynamic Page with two report regions (both standard type of 'SQL Query'). The second report region is the one causing us the headache. The column headings are set to 'Custom' but apart from that everything seems as it should be.
The following query populates an HTML table being generated in the second report region (problem line in bold):
SELECT apex_item.hidden(7,task_id)||
apex_item.select_list_from_lov(1, estimate_type, 'TASKSMK', NULL, 'YES', 0,'** Select Task **',NULL, NULL) as "Task Type",
'<img src="/i/themes/aqa/required.gif" alt="Required Field" tabindex="999" />'||apex_item.text(2, description,30,4000,'required="true"') as "Work Item(s)",
dbms_lob.substr(apex_item.select_list_from_lov_xl(3, username, 'PEOPLE', NULL, 'YES', 0, '** Select Resource **', NULL, NULL),4000) as "Resource",
apex_item.text(4, days,5,5) as "Days",
apex_item.text(5, start_date,11,11) as "target Start (dd-mon-yyyy)",
apex_item.text(6, NVL(end_date,ADD_MONTHS(start_date,1)),11,11) as "Target End (DD-MON-YYYY)",
rownum link
FROM
(SELECT t.task_id,
e.estimate_type,
t.description,
t.username ,
t.days,
t.start_date,
t.end_date
FROM estimate e, task t
WHERE e.project_project_id = TO_NUMBER(:F172_PROJECT_ID)
AND e.active_yn = 'Y'
-- and t.days > 0
AND t.ese_id = e.id
--AND e.creation_date = (SELECT MAX(ei.creation_date) FROM estimate ei WHERE ei.project_project_id = e.project_project_id AND ei.active_yn = 'N')
UNION ALL
SELECT 0 task_id,
0 estimate_type,
NULL description,
'0' username,
NULL days,
sysdate start_date,
ADD_MONTHS(sysdate,1) end_date
FROM dual
CONNECT BY LEVEL < = TO_NUMBER(:P19_ROWS_CNT))
All appears well until the number of values being returned in the second LOV (retrieved by the apex_item.select_list_from_lov_xl) exceeds 4000 characters and then we get the error first detailed. The substr around the function isn't usually present, it was added during the debugging, if I allow one more character than the 4000 or remove the substr completely then I get the error again. If the same function is used to retrieve the LOV on a normal Dynamic Form field then all is well, it only seems to have a problem when present in the HTML table being generated.
Are we doing something silly here?
Thanks.

I cannot sort my songs using the "plays" column (also known as the number of plays column). The number of "plays" is not increasing as a song finishes.

The "plays" column (also known as the number of plays column) is not saving not saving the number of plays (v 11.0).

My number of 'Plays' was not increasing anymore at some point after updating to Version 11. I had iTunes rev 11.0.1.12. Today I updated to the latest rev 11.0.2.26, and now the numer of plays is increasing, so they must have fixed the bug!

Unable to setup fixed number of report columns based on a dynamic query

Hi guys, I need to find a way to replicate below output. Unfortunately it cannot be done using the column group feature due the fact it will create not so many rows as I need. In the below case it would create
only four columns. I need 10 columns. Basically for 100 m 6 columns would remain blank . 8 for 200 m .I'm using SRSS 2008R2
Query results:
Race Name Ranking
100m Andrew 1
100m Rachel 2
100m Chris 3
100m Drew 4
200m John 1
200m Billy 2
Report output should look like:
Race 1 2 3 4 5 6 7 8 9 10
100m Andrew Rachel Chris Drew
200m John Billy
Any suggestions?

As I understand, you want a fixed number (10) of columns and you want them whether or not there are 10 rows returned by your dataset for a given race.
What is your dataset?
What if your dataset returns 15 races of a given type? Do you want 15 columns then?
Assuming your dataset is TSQL, you can use a matrix in your report if you tweak your dataset query. First, you need to add a "default" set of data that guarantees your 10 columns. This can be done with a set of UNION statements:
UNION
SELECT '100m' AS Race, '' AS Name, 1 AS Ranking
UNION
SELECT '100m' AS Race, '' AS Name, 2 AS Ranking
UNION
SELECT '100m' AS Race, '' AS Name, 3 AS Ranking
UNION
SELECT '100m' AS Race, '' AS Name, 4 AS Ranking
UNION
SELECT '100m' AS Race, '' AS Name, 5 AS Ranking
UNION
SELECT '100m' AS Race, '' AS Name, 6 AS Ranking
UNION
SELECT '100m' AS Race, '' AS Name, 7 AS Ranking
UNION
SELECT '100m' AS Race, '' AS Name, 8 AS Ranking
UNION
SELECT '100m' AS Race, '' AS Name, 9 AS Ranking
UNION
SELECT '100m' AS Race, '' AS Name, 10 AS Ranking
This gives you the 10 columns. In the matrix, set row group to Race and column group to Ranking. Set the intersecting detail cell to:
=Max(Fields!Name.Value)
This will give you 10 columns unless you have more than 10 rows returned for a given race.

The number of display columns in the report reached the limit. Help!!!

Hello Everyone,
This might be dumb question. But why do get this error with a IR report? and what is the solution for this. Please help me with this.
Error
The number of display columns in the report reached the limit. Please click Select Columns under Actions menu to minimize the report display column list.
Oh.. And also i have a blob column.. if the format is not given, then the table is fine.. but happen to get this error only when the blob download format is given.
Thanks and regards

Hi,
i have set up a small test case on apex.oracle.com and I receive the same error if I use download format.
I have a table
test_blob (id number, name varchar2(10), blobcont blob)
If I create IR like
select
    id,
    name,
    blobcont
from test_bloband then I define download format I hit the error.
If you want this to work you have to change your query to
select
    id,
    name,
    dbms_lob.getlength(blobcont) blobcont
from test_blobAnd then again define download format for blob on blobcont column.

Why is there a limit on the number of times a "DVD player region" can be changed, and can it be adjusted for more region changes, or an indefinite number of region changes?

Why is there a limit on the number of times a "DVD player region" can be changed, and can this numbert be adjusted for more region changes, or an indefinite number of region changes?

Region encoding is the mechanism that enables motion picture studios to control the worldwide release of their movies. It is required by the DVD Forum (http://www.dvdforum.org/forum.shtml) in all commercial hardware DVD players. Every DVD-Video disc contains one byte of data representing a region code, which limits where the disc can be played.
http://support.apple.com/kb/HT2397
Once you have set the region in DVD Player five times it cannot be changed.
Instead, use VLC to view videos from different regions:

The number of display columns in the report reached the limit" Interactive Report

I get the error message of "The number of display columns in the report reached the limit" when trying to display less than 100 (100 is limit) columns when an aggregate has been created.   This does not happen when an aggregate has not been added to the IR report. It seems to happen because I have a control break on as well. When I turn off the control break it works but is not the result that we want. Interesting enough, if I filter the results down to 500 rows it works just fine. Does oracle treat aggregates as columns!? This is a really odd issue that I really need to clear up.

Dynamic region column for different user?

Hi experts,
I am developing a system for users with different privileges level corresponding to regions(state, city, country).
National users could access states data within the nation, state users could access cities data within the
state and so on for city users.
I have a region hierarchies(state, city, country) and I was wondering if it can work:
when national users log on, they will see table like this: region column (hierarchies)+ data column
state
data
For state users:
city
data
Besides developing three separate tables for these type of user, how can I achieve this with one table? Can the region column change dynamically corresponding to different users and also the column have drill down function ?
Hope I make my question clear, any suggestion will be appreciated . If this question had been asked, sorry about that and pls send me the link.
regards,
Jeff

HI,
You can done this by using "Data Level Security" and "Object Level Security".
Step 1:
Create the hierarchy as level1 Contains state and level 2 contains city.
step:2
Drag to presentation and right click on the hierarchy of level1 (State)
Step3: Go to Permissions get the online user go to the particular user and give access to read for the state user and no access for city user.
Step4: Right click on the level2 (City) and go to permission and set the user access to read for city user and no access for state user.
Check inconsistency and save the RPD.
Check in the report side.

Hi,
On comparison with 1st query and 2nd query,it can be easily noticed that ,1st query is returning 4 columns and 2nd query returns 5 columns in select clause.
In order to work union ,both of your queries should select equal no of columns.
Hence replace your query
Original query(1st ) :
SELECT FLROOPENHEAD.RONBR RepairOrder,FLROOPENHEAD.DATEOPENED DateOpened,NULL DateClosed,
(SELECT FLREPAIRSTAT.DESCRIPTION FROM FLREPAIRSTAT
WHERE FLREPAIRSTAT.REPAIRSTATID = FLROOPENHEAD.REPAIRSTATID) RepairOrderStatus,

DateClosed,

Sbwp: limited number of dynamic columns

Hi together,
We use dynamic columns in sbwp.
Unfortunatelythe number of dynamic columns is limited to six.
Is there a chance to use more than six dynamic columns?
Thanks for any help.

No,
You could use 1 column for more than 1 piece of data.
What is the weird business requirement that they need more than 6 dynamic columns?
Kind regards, Rob Dielemans

                Dim oMenus As SAPbouiCOM.Menus
                Dim omat As SAPbouiCOM.Matrix
                Dim GCols As SAPbouiCOM.Columns
                Dim i As Integer
                oitem = OForm.Items.Item("Ur Matrix")
                omat = oitem.Specific
                GCols = omat.Columns
                omat = OForm.Items.Item(selItem).Specific
                For i = 1 To omat.RowCount
                    If omat.IsRowSelected(i) = True Then
                        omat.DeleteRow(i)
                        Exit For
                    End If
                Next
            Catch ex As Exception
                SBO_Application.MessageBox(ex.Message)
            End Try
        End If
It will work..
