Custom Breaking of more than three columns - apex 3.0

Trying to create an application that has more than 3 columns for break formatting - have read of a technique thats quite long winded using decodes and grouping sets etc - but seems a bit complex for such a (supposedly) simple query.
Just wondering if anyone else has come across an easy way to do this - including potentially modifying the template etc to allow more than the default values for breaking options?
Thanks!

Hi,
Excellent example in this thread of how to achieve what you want using the LAG Function: -

How to create and handle sharepoint custom list with more than 300 columns?

Hi,
I have requirement for our project where in the input form is having around 320 columns in it.below are the columns and data types.
Single line of text-180
Yes or No Radio button -95
Date time control-35
Checkbox-10
I have checked the sharepoint boundry and limits for columns and data types.
https://technet.microsoft.com/en-us/library/cc262787.aspx
But how can we handle a sharepoint list with these many large number columns.
Is it safe to create all columns in a single list?
How it will impact the performance?
What is the other approach acheive this requirement?
Any help would be appreciated.
Regards,
Poovi

Hi,
According to your description, my understanding is that you want to know if it has some performance issue and limitation when create large number column in a list.
When creating columns in the list , you can still create all 320 columns in the list. But when retrieve the items in a view, then there is a list view threshold limit which causes the performance issue, see the link below:
Sharepoint list column limit
To handling the large number columns, I suggest you can distinguish the column with business logic to create in different list, it will be clear to display the logic relationship.
Thanks

Reports with more than 100 columns

I am using Apex 3.2. I am using a classic report with more than 100 columns. So to use the custom heading in the report, I exported the page,did modification in exported sql file and imported back.
But when I am passing the parameters from a input screen for the first time either it is showing the all data avilable in the database or with only header. If I do the refresh in input screen and try it then it is working as intended. I am updating at the below loaction of the page.Let me know if I have to update anything more in the sql file.
declare
s varchar2(32767) := null;
begin
s := null;
wwv_flow_api.create_report_columns (
p_id=> 200100535534034253 + wwv_flow_api.g_id_offset,
p_region_id=> 2003453533453 + wwv_flow_api.g_id_offset,
p_flow_id=> wwv_flow.g_flow_id,

Hi,
Its just a general thought and I realize you know your application and user community better I do, but do you think your users are going to be very happy when they are presented with a report with more than a hundred columns? Have you considered maybe presenting the data in some sort of rolled up form from which the user can then drill down to the data they are particularly interested in. Also, I'm sure your LAN administrator would be happy not to see 100+ column by x number row reports being regularly shipped across the network.
Also, 100+ column reports suggests tables with 100+ columns which are probably not designed in a very relationally compliant way. I find that good DB design usually results in applications that have to make less compromises, such as hacking export files in order to fool the API into making ridiculous, unsupported and unsupportable compromises.
Just a thought..................

I am sure this has been discussed here before. Search the forum...good luck.It is possible using a template, and it has been discussed many times...
The trick is to combine classTyler's conditional <tt>class</tt> technique with a custom named column report template.
Determine a class for the row in the query:
select
 empno
 , ename
 , sal
 , case
 when sal < 1000 then 'low'
 when sal between 1000 and 2000 then 'medium'
 when sal > 2000 then 'high'
 end sal_class
from
 empCreate a custom named column report template, referencing the class in the row template:
<tr class="#SAL_CLASS#"><td>#EMPNO#</td><td>#ENAME#</td><td>#SAL#</td></tr>Then create a style sheet to apply the required backgrounds:
tr.low td { background-color: yellow; }
tr.medium td { background-color: white; }
tr.high td { background-color: red; }

How to display more than 60 columns in a report

I have a table defined as follows
id
column_name
column_value
data sample
id col_name column_value
1 col1 val1
1 col2 val2
1 col3 val3
2 col1 val1
2 col2 val2
2 col3 val3
now I want to display the data in a report as follows
id col1 col2 col3
1 val1 val2 val3
2 val1 val2 val3
I was able to generate output using pivots [http://technology.amis.nl/blog/1197/pivot-dynamic-data]
the problem is that I can have more that 60 columns retrieved in each row, the pivot solution will retrieve them correctly but I can't display more than 60 columns in apex reports, why this restriction in apex, any solution

Hello:
In the Source section of the report definition choose 'Use Generic Column Names (parse query at runtime only)' and then specify a suitable value for 'Maximum number of generic report columns:'

Is there a way to open CSV files with more than 255 columns?

I have a CSV file with more than 255 columns of data. It's a fairly standard export of social media data that shows volume of posts by day for the past year, from which I can analyze the data and publish customized charts. Very easy in Excel but I'm hitting the Numbers limit of 255 columns per table. Is there a way to work around the limitation? Perhaps splitting the CSV in two? The data shows up in the CSV file when I open via TextEdit, so it's there. Just can't access it in Numbers. And it's not very usable/useful for me in TextEdit.
Regards,
Tim

You might be better off with Excel. Even if you could find a way to easily split the CSV file into two tables, it would be two tables when you want only one. You said you want to make charts from this data. While a series on a chart can be constructed from data in two different tables, to do so takes a few extra steps for each series on the chart.
For a test to see if you want to proceed, make two small tables with data spanning the tables and make a chart from that data. Make the chart the normal way using the data in the first table then repeat the following steps for each series
Select the series in the chart
Go to Format sidebar
Click in the "Value" box
Add a comma then select the data for this series from the second chart
Press Return
If there is an easier way to do this, maybe someone else will chime in with that info.

Group by on more than 2 columns in SharePoint List

Hi,
Is there any way to use Group-by on more than 2 columns? I know there is a way using SPD which I have implemented as well, however it makes the page READ-ONLY.
Any other way? May be using custom code?

More than one column retrieved in "report and form" page

HELLO!
let's see if anybody can help me with this... i'm sure it's a stupid problem but i really don't know how to solve it.
when i create a new application with APEX, i want to add a "report and form" page. i select the table where de data is, and then click on add page. then i go to the page definition for the form that just has been created but there's no option for selecting more than one column as the link column...
i mean, i want to show a report with all the columns from the table and then, by selecting one of them, the form should display that column but the problem is that the primary key of the table is formed by 6 columns and i always receive the "more than one column retrieved" message as it's trying to retrieve the information using only one column. is there any way to make the link column be composed by 6 or 7 columns??

APEX can handle 2 primary key for one table (if you are using the automated fetch row and the automated process row).
In your case, you'll have to create your own "fetch process (page rendering)" and "DML process (page processing)".

Row chaining in table with more than 255 columns

Hi,
I have a table with 1000 columns.
I saw the following citation: "Any table with more then 255 columns will have chained
rows (we break really wide tables up)."
If I insert a row populated with only the first 3 columns (the others are null), is a row chaining occurred?
I tried to insert a row described above and no row chaining occurred.
As I understand, a row chaining occurs in a table with 1000 columns only when the populated data increases
the block size OR when more than 255 columns are populated. Am I right?
Thanks

dyahavYesterday, I stated this on the forum "Tables with more than 255 columns will always have chained rows." My statement needs clarification. It was based on the following:
http://download.oracle.com/docs/cd/B28359_01/server.111/b28318/schema.htm#i4383
"Oracle Database can only store 255 columns in a row piece. Thus, if you insert a row into a table that has 1000 columns, then the database creates 4 row pieces, typically chained over multiple blocks."
And this paraphrase from "Practical Oracle 8i":
V$SYSSTAT will show increasing values for CONTINUED ROW FETCH as table rows are read for tables containing more than 255 columns.
Related information may also be found here:
http://download.oracle.com/docs/cd/B10501_01/server.920/a96524/c11schem.htm
"When a table has more than 255 columns, rows that have data after the 255th column are likely to be chained within the same block. This is called intra-block chaining. A chained row's pieces are chained together using the rowids of the pieces. With intra-block chaining, users receive all the data in the same block. If the row fits in the block, users do not see an effect in I/O performance, because no extra I/O operation is required to retrieve the rest of the row."
http://download.oracle.com/docs/html/B14340_01/data.htm
"For a table with several columns, the key question to consider is the (average) row length, not the number of columns. Having more than 255 columns in a table built with a smaller block size typically results in intrablock chaining.
Oracle stores multiple row pieces in the same block, but the overhead to maintain the column information is minimal as long as all row pieces fit in a single data block. If the rows don't fit in a single data block, you may consider using a larger database block size (or use multiple block sizes in the same database). "
Why not a test case?
Create a test table named T4 with 1000 columns.
With the table created, insert 1,000 rows into the table, populating the first 257 columns each with a random 3 byte string which should result in an average row length of about 771 bytes.

Paraphrase misspelled the view name "V$SYSSTAT", corrected a couple minor typos, and changed "will" to "may" in the closing paragraph as this appears to be the behavior based on the test case.

I can able to display single column values in tree control by setting the nodedifinition property in tree control. i can't able to display more than one column in tree control.
any idea about this problem

Drill down using more than three items

Is it possible to supply more than three parameters to the column link?
I am making a drill down from summary report to the detail report, and I need to pass five parameters to the detail report. The list of items under
Application Builder > Application X > Page Y > Report Attributes > Column Attributes > Link
is limited to three items. Is there a way around this limitation?
Thanks,
Tim

You need to change you link type from Page In This Application to URL. You'll then need to encode each parameter name and it's value into the last two elements of the f?p format. You can use a two or three parameter URL as an example and just modify from there. 
 
For example (from one of my applications): 
 
f?p=101:13:::NO::P13_NAME,P13_SEQ_ID:Lee%2C396 
 
The relevant part is the last colon (or the fields on either side of it more specifically). The first set of fields P13_NAME,P13_SEQ_ID are my page item names on the destination page (where we're going) and the last two Lee%2C396 are their values from the source page (where we're coming from). The %2C is an encoded comma. In order to get this in your output, you want to set your URL to something like: 
 
f?p=101:13:::NO::P13_ITEM1,P13_ITEM2:&P12_ITEM1.,&P12_ITEM2. 
 
I'm doing this from memory since I can't find a good example for you, but I think I'm pretty close in the syntax. 
 
Hope it helps.

More than three TVS

I just signed up for FIOS TV not installed yet. Will FIOS TV support more than three TVs?
I have cable TV now and have 4 analog TVs plus 1 HD with coax cable to each TV. Normally use just three TVs.
Can additional digitial adapters be rented when family is in town? What would I need to do?
Thanks ahead of time.

Yes, FiOS supports more than 3 TVs. I originally had 2 HDTV's and 2 Ananlog TV's hooked up along with 20/20 Mbps Internet service. I cut back on the FiOS internet speed to become a Verizon Triple Freedom customer (land line, internet, ExtremeHD TV programming). Ask the tech when he comes out to intall in reference to the other part of your question..

How to create combobox to display more than one columns

I need kind help with the following question. As the combobox includes two pieces--textbox and the combobox list. Then how to create a combo box bean, which is based on table EMP(empno number(6), ename varchar2(40)) records for example, to achieve these features:
1) allow more than one columns to be displayed in its records list--e.g., I need to show these records:
empno (value) ename (label)
103 David M Baker
104 David M Baker
105 Kelly J Volpe
106 Krista F Carpenter
107 Michelle P Silverman
The two 'David M Baker's are different employees, but unfortunately, with the same name.
2) allow combo box list to return the column value 'empno' even though it shows both columns as above. i.e., if user picks the second record above, then the combobox list returns 104 to the textbox in the background, but the 'David M Baker' is displayed on the textbox. Of course the combobox list may return 'David M Baker' if needed when there is only one column in the list as the current standard feature.
3)allow partial match search by typing in some letters. i.e., if user types in the textbox of the combobox letter 'K' or 'k' then the partially matched records
105 Kelly J Volpe
106 Krista F Carpenter
should be automatically displayed in the combobox list, not the whole list as above; then user may double click to choose one of the two or if user continues to type in 'R' or 'r', then the uniquely matched record 'Krista F Carpenter' is displayed in the textbox and the 106 is returned to the textbox.
4) as a bonus if it's doable, allow combobox to return values to different textboxes when its records list has more than one columns.
The reason I need these features is that I am working on the project migrated from Microsoft Access applications to centralized Java version web application. We at beginning promised to users community that Java swing will provide all the GUI user friendly features Microsoft Access has, but now we got stucked--we ate our words and got tons of complains from our users community. This is just the most needed component I posted here. I really hope that Java would add all the default GUI user-friendly features to compete with MS since its Win95 GUI has been accepted as industry standard. And most users are used to it. They claimed that they don't know and don't care what tool you use the newly created application should be more user friendly, not the opposite.
I would be very much appreciated if any one would help me with this item.

Thanks for your comments. I think nobody expects Sun to write everything including special features for its components. But I do think Sun should provide at least those standard user-friendly features for the GUI components because most users have been used to the GUI user-friendly features provided by Win95 and Access/Excel applications. Then this will help us to productively create applications to beat MS applications.
Other wise like me, to get the existing GUI features, existed in old MS Access application, for our migrated Java application, I must re-create the GUI components library first which is a big burden to me at least, for others it might be fun for coding on their own from scratch, but I have to focus on the timing of project.
If you really can pass the request to Sun and push them move a bit, please pass these words: before Sun starts to revise them, please play around window GUI, e.g., Access/Excel applications, then plan what to do, the bottom line is to equally match or better than them in FUNCTIONALITY(Look and feel is not my focus here). Don't ignore the influence of Windows regardless of you hate it or love it, the reality is most users are so familiar with windows GUI features which are accepted as industry standard. Thus the choice is to match or better to beat them. Don't make your car by closing your door, don't assume users will like what you come out in a closed room.
