How to create a dynamic table were the JTable columns keep varying

How to create a dynamic table were the JTable columns keep varying based on the input to the jtable

Oooh, I lied. DefaultTableModel has an API for adding and
removing columns. I didn't know that. You should have read
the API.
As for preferring to extend AbstractTableModel rather than
DefaultTableModel, I think it's more correct. DefaultTableModel
is a simple implementation of Abstract for basic cases. It isn't
intended to be extended. I figure most people extending
DefaultTableModel are also extending JFrame, JPanel, and Thread
instead of encapsulating the first two and implementing
Runnable for the third.

How to create a temp table in the memory, not in disk?

in sql server, you can create a temp table in the memory instead of disk,
then you can do the insert, delete,update and select on it.
after finishing, just release it.
in Oracle,
I am wonderfing how to create a temp table in the memory, not in disk?
thanks,

Thanks for rectifying me Howard.
I just read your full article on this too and its very well explained here:
http://www.dizwell.com/prod/node/357
Few lines from your article
It is true, of course, that since Version 8.0 Oracle has provided the ability to create a Keep Pool in the Buffer Cache, which certainly sounds like it can do the job... especially since that word 'keep' is used again. But a keep pool is merely a segregated part of the buffer cache, into which you direct blocks from particular tables (by creating them, or altering them, with the BUFFER POOL KEEP clause). So you can tuck the blocks from such tables out of the way, into their own part of the buffer cache... but that is not the same thing as guaranteeing they'll stay there. If you over-populate the Keep Pool, then its LRU mechanism will kick in and age its contents out just as efficiently as an unsegregated buffer cache would.
Functionally, therefore, there can be no guarantees. The best you can do is create a sufficiently large Keep Pool, and then choose the tables that will use it with care such that they donâ€™t swamp themselves, and start causing each other to age out back to disk.
Thanks and Regards

How to create a Dynamic table without knowing fieldcat size

Hi all, i'm trying to insert a (Jointer) of 3 selections form diffrent tables in an other dynamic table but i dont know the size of my final table, so i dont know how to create a fieldcatalog.
Can we create an internal table with those caractiristics ????

Hi,
If you know which fields (ABAP Dictionary) you're selecting then you know their size; use the following FM call: DD_NAMETAB_TO_DDFIELDS
Then you can use the following method to create your dynamic table: cl_alv_table_create=>create_dynamic_table

How to create a dynamic table region with dynamic VO

Hi All,
I have a requirement to create a dynamic table region with a dynamic VO.
I need this because at runtime only the user will select the table name. So based on that table name, i have to create a table region to display the records.
I already created a dynamic VO. Could anyone share the code for dynamic table region creation.
Thanks in Advance.

Hi,
You can use following sample code to create advance table columns dynamically with colum groups as well.
It assumes that you have already created advance table with ID EmpTblRN.
Below code returns column heading dynamically and if you keep your VO column names and attributes
same in all the cases (COL1, COL2.....) then you can easily use a loop to create advance table columns.
It is attaching VO attributes to OAMessageStyledText bean in the last.
Hope it helps.
OAAdvancedTableBean advTable = (OAAdvancedTableBean)webBean.findChildRecursive("EmpTblRN");
Serializable [] param = {currentWindowSeq.toString()};
Datum[] colHeadingArray = (Datum[])am.invokeMethod("getColumnHeading", param);
String oldGrpName = null;
String newGrpName = null;
OAColumnGroupBean columnGroup = null;
DictionaryData columnFormat = new DictionaryData();
columnFormat.put(WIDTH_KEY, "4%");
for (int i = 0; i < colHeadingArray.length; i++)
try
oracle.sql.STRUCT os = (oracle.sql.STRUCT)colHeadingArray;
Object[] colHeadAttr = os.getAttributes();
newGrpName = (String)colHeadAttr[0];
if(newGrpName!=null)
if(!newGrpName.equals(oldGrpName))
// Create a column group, create the set the column header,
// and add the column group under the advanced table
columnGroup = (OAColumnGroupBean)createWebBean(pageContext, COLUMN_GROUP_BEAN, null, "ColGroup"+i);
OASortableHeaderBean columnGroupHeader = (OASortableHeaderBean)createWebBean(pageContext, SORTABLE_HEADER_BEAN, null, "ColGroupHeader"+i);
columnGroupHeader.setText(newGrpName);
// Retrieve from message dictionary
columnGroup.setColumnHeader(columnGroupHeader);
advTable.addIndexedChild(columnGroup);
oldGrpName = newGrpName;
// Create a column, create the set the column header, and add the column
// under the column group
OAColumnBean column1 = (OAColumnBean)createWebBean(pageContext, COLUMN_BEAN, null, "Column"+i);
OASortableHeaderBean column1Header = (OASortableHeaderBean)createWebBean(pageContext, SORTABLE_HEADER_BEAN, null, "Column1Header"+i);
column1Header.setText(colHeadAttr[1].toString());
column1.setColumnHeader(column1Header);
column1.setColumnFormat(columnFormat);
columnGroup.addIndexedChild(column1);
// Create the actual leaf item under the first column
OAMessageStyledTextBean leaf1 = (OAMessageStyledTextBean)createWebBean(pageContext, MESSAGE_STYLED_TEXT_BEAN, null, "Leaf"+i);
//OARawTextBean leaf1 = (OARawTextBean)createWebBean(pageContext, RAW_TEXT_BEAN, null, "Leaf"+i);
leaf1.setViewAttributeName("Week"+(i+1));
String destination = "OA.jsp?page=/xxqc/oracle/apps/per/leaveadvance/webui/EmployeeLeaveDetailPG&personId={@PersonId}";

How do I create a dynamic table in the form for auto field detection?

I am new to Acrobat. We need to create a form template that contains dynamic table control so that it can be populated using auto field detection.
Our dynamic table contains reimbusement information, the rows vary from one claim to another.
Please help. We are having Acrobat 9 Pro.
Thanks

A lot is possible. There is a scripting language which should fill the gaps of missing features. There is data merge, there is XML, there is InCopy. Read everything about it and you will surely find what you need.

How to create a partition table on the basis of substring of column val

Hi All,
I have table
Create table Mytable
( Col1 number,
Col2 number,
Col3 varchar2(20)
insert into mytable values(11,2,'20110901');
insert into mytable values(12,2,'20110902');
insert into mytable values(13,2,'20110903');
insert into mytable values(14,2,'20110904');
insert into mytable values(15,2,'20110905');
insert into mytable values(16,2,'20110906');
Col3 data have the date value in the form of yyyymmdd format.
I want to create a 30 partitions on the basis of day on col3.
how can i achive this. i tried range partition but how can i get day of col3?
any help appriciated.
Edited by: P:) on Sep 28, 2011 5:56 PM

Hi,
the first point would be to use the correct data type for col3 and make it a date. Then I can see no reason why you couldn't range partition based on the date.

How to create a dynamic table (repeating) with static header?

Hello
My purpose is to create a table which should be dynamically filled at runtime depending on the number of elements in the datasource($record.list). If the list is empty, the table shouldn't be displayed at all.
I created a subform which holds a table, ticking "Repeat Subform for each data item" and I set the binding of the table elements to $record.list[*].myelement. This works fine so far.
For the table header I created a second subform with a table having exactly the same size like the other table with text fields that contain the table header texts.
My problem now is that I would like to control the display of the subform which serves as table header row depending on whether $record.list is empty or not.
What's the best way to do this? How can I have access to the datasource for a form?
Thank you very much for your help!!!
Best regards
Bettina Hepp

Hi,
Instead of creating the header row outside the table.
Create it inside the same table as header row.
So when you create a condition then automatically applicable for the header row also.
This is the best option.

How to create a dynamic fields in the Adobe Interactive form ?....urgent...

Hi Experts,
I'm working on Adobe Interactive form developed in WDP ABAP.( I have successfully config the ADS in my server.)
Action:
1. Create two view -
first_view and second_view in the WDP ABAP..
2. In the first_view, there are a input field( named "elements_number") and a button(named "create_button") .
3. In the second_view, there is Adobe Interactive form ( named "adobe_form" ).
4. Run the WDP ABAP: first_view is opened. Type a number ex."3" in the "elements_number", click the "create_button".
5. The second_view is opened.
6. The "adobe_form" is occured.
7. There are 3 text_fields in the "adobe_form".
Steps (1) ~ (6), I have completed, but I don't know how to implement the step (7).
Please give me some hint on this. I try to use the CL_WD_ADOBE_SERVICE, but I didn't found any examples. Do you give me some ways to implement the function? Thanks a lot.
Thank you very much.
Thanks,
Tao

Hi Philippe,
Thank you very much in advance.
Do you tell me how to hide elements in the "adobe_form" in the WDP ABAP? How can I get the elements attributes in the "adobe_form" from the method WDDOMODIFY of the second_view in the WDP ABAP.
Please give me some hints on this. Do you give me some ways to implement functions( hide elements and get elements's attributes)? Thanks a lot.
Thank you very much.

Oracle supports feedback form metalink was; "What you exactly want to approach is not possible in Htmldb"
I can guess that it is not
exactly possible since I looked at the forums and documantation etc. but
couldnt find anything similar than this link; "http://www.oracle.com/technology/products/database/htmldb/howtos/tabular_form.h
t". But this is a very common need and I thought that there must be at least a workaround?
How can I talk or write to Html Db development team about this since any ideas, this is very important item in a critial project?
I will be able to satisfy the need in a functional way if I could make the
select lists in the tabular form dynamic with the noz_id;
SELECT vozellik "Ãzellik",
htmldb_item.select_list_from_query(2, t2.nozellik_deger, 'select vdeger
a,vdeger b from tozellik_deger where noz_id = 10') "Select List",
htmldb_item.text(3, NULL, t2.vcihaz_oz_deger) "Free Text"
FROM vcihaz_grup_ozellik t1, tcihaz_oz t2
WHERE t1.noz_id = t2.noz_id
AND t2.ncihaz_id = 191
AND t1.ngrup_id = 5
But what I exactly need i something like this dynamic query;
SELECT
vozellik "Ãzellik",
CASE
WHEN (t2.nozellik_deger IS NULL AND t2.vcihaz_oz_deger IS NOT NULL) THEN
'HTMLDB_ITEM.freetext(' || rownum || ', NULL) ' || vozellik
WHEN (t2.nozellik_deger IS NOT NULL AND t2.vcihaz_oz_deger IS NULL) THEN
'HTMLDB_ITEM.select_list_from_query(' || rownum ||
', NULL, ''select vdeger a,vdeger b from tozellik_deger where noz_id = ' ||
t1.noz_id || ''' ) ' || vozellik
END AS "DeÄer"
FROM vcihaz_grup_ozellik t1, tcihaz_oz t2
WHERE t1.noz_id = t2.noz_id
AND t2.ncihaz_id = 191
AND t1.ngrup_id = 5
Thank you very much,

Drop down in dynamic table in the Adobe Interactive Form (Web dynpro ABAP)

Hi All,
I have scenario use drop down in dynamic table in the adobe interactive form (Using the button the dynamic table row will be increasing and decreasing).
Assume I Add five rows dynamically in the dynamic table. The Last column contains Drop down.
I have button in the adobe form.
Button Name = u201CSAVEu201D
Button type    = SAP Submit button (Native type u2013 I am Using ZCI).
While clicking save button, I need to store the dynamic table datau2019s to back end system. I can able to store the data to back end system. After form data getting saved those particular values need to display in the adobe form.
Here I am facing a problem.
I cannot able to view as a default value in the drop down, which I have selected some values after save operation I am not getting any values in the drop down as a default.
Example:
The dynamic table contains 5 rows (Each and every row Drop down contains one to ten values).
1)     I have selected second value in the Drop down (ROW1)
2)     I have selected fourth value in the Drop down (ROW2)
3)     I have selected fifth value in the Drop down (ROW3)
4)     I have selected seventh value in the Drop down (ROW4)
5)     I have selected third value in the Drop down (ROW5)
I press the save button that particular Drop down value gets saved in back end system and that particular values want display in the Drop down as a default value.
