Multiselection in Tables with Master Column
The use case is the following:
I have a table with a master column in which I display a tree. The table is bound to a dataSource with a recursive node.
I'd like to implement multiple selection for the rows of this table, but it doesn't work (even when making context node's selection 0..n).
Is there any work-around for solving this problem?
Thanks for the suggestion.
But there is still problem with this:
I will have have two methods for selection of rows of the table - there will be standart one which is provided by webdynpro and additionaly I will have a column of checkboxes. It is not convinient form user-perspective. Furthermore I can't put columns on the left of the master column which is also a problem, the checkboxes should be situated in the firs column.

Selection in table with Master Column
Hi,
can anybody explain me how selection works in table with MasterColumn (TreeByNestingTableColumn)?
I've created a table with several columns and the "master" one behaves differently from others.
First of all, leaf elements of master column are not clickable (i.e. I don't receive notification "onLeadSelect" from the table, when user clicks in the cell of leaf element of the column). With expandable elements I receive loadchildren event and can react on selection.
I'm using TextView as cell editor, will try LinkToAction, may be it will resolve situation, but it's rather workaround as solution
Second, getLeadSelection doesn't work anymore for the table - it works with indexes of top level elements only.
However onLeadSelect action brings me selected row number, which I somehow should map to the tree.
I.e. when I get "25" as selected element, I recursively traverse context node to find 25th element. Which is rather slow operation as for any selection I have to reiterate whole structure and I hope that visual appearance is similar to context element order.
May be there is simplier ways to get selected element by its index in "flat" list?
And one another strange thing: first click on the table sends me onLeadSelect "0", but highlight points to the element user clicked - not necessary first one.
Context node is "single" selection, initLeadSelect=true,
selection = 0..1 (with 1..1 setTreeSelection doesn't work - method I want to use to be able to select a node in hierarchy on my own)
all quite similar to other tables I have, which works well. Just the problems with the table, where Master Column is used.
Thank you!
Best regards,
Nick>Valery's proposal was to perform reverse traverse from current element to root and summarize parent element indexes.
It seems to work:
in method, which sets selection I applied
// we need to know index of the element not in whole context, but in scope of table-relevant node
int index = getIndexInContext(selElement, wdContext.currentXXXElement());
IContextElement curContext = wdContext.currentContextElement();
int firstVisibleRow = curContext.getTableFirstVisibleRow();
int visibleRows = curContext.getTableVisibleRows();
if (index < firstVisibleRow || index > firstVisibleRow + visibleRows) {
curContext.setTableFirstVisibleRow(index);
and method getIndexInContext looks as:
private int getIndexInContext (IWDNodeElement element, IWDNodeElement root) {
int index = element.index();
if (element == root) {
return index;
IWDNodeElement parent = element.node().getParentElement();
if (parent == null) {
// do whatever you like here for error diagnostic
myMsgMgr.reportException("Internal Error: getIndexInContext - element is not under passed root", false);
return 0;
// +1 - every level adds 1 (otherwise indexes of first children of hierarchy will be 0)
return index + getIndexInContext(parent, root) + 1;

What can I do so that this table gets imported correctly?
Also tell me "whether the BLOB is stored in different tablespace than the default tablespace of the user?"
Thanks in advance.Hello,
U can either
1) create a tablespace with the same name in destination where you are trying to import.
2) get the ddl of the table, modify the tablespace name to reflect the existing tablespace name in destination and run the ddl in the destination database, and run your import command with option ignore=y--> which will ignore all the create errors.

HOW TO CREATE A TABLE WITH 800 COLUMNS?
I have to create a table with 800 columns.I know the create statement to create a table but it will take more time.
So tell me the other method.If you really think that you have to store 800 values for a given entity, it would be a wise idea if you store you information in columnar fashion. Make a main table and a attribute table, keep the primary identifier in the main table and store other attributes in the attribute table where you can keep the primary key of the first table as foreign key (not necessary) to maintain the relationship.
eg.
emp_id
emp_name
dob
city
state
country
pincode
1
Mr X
01/01/1990
ABC
ZXC
MMM
12345
Can be stored as
Main Table
emp_id
emp_name
1
Mr X
Attribute Table
attr_id
emp_id
attr_nam
attr_value
1
1
dob
01/01/1990
2
1
city
ABC

How to create a table with editable column values.
Hi everyone,
I think this is very simple but i'm not able to find how to do this. This is my requirement. I need to create a table with n columns and 1 row initially. user should be able to enter data into this table and click of a button should insert data into the data base table. Also there should be a button at the bottom of the table to add 1 row to the table.
I know how to do the insert to database, but can anyone please let me know how to create a table that allows user to enter data and how to create a add 1 row button?
Thanks in Advance!Raghu,
Go through the ToolBox tutorial Create Page & Advanced table section of OAF Guide.
Step 1 - You require to create EO & a VO based on this EO. This EO will be of DataBase table where you want to insert the data.
Step 2 - Create a Advanced table region. (Refer this Adavanced table section for more on this)
Step 3 - Attach this VO in the BC4J component of Adavanced Table region.

How to read/write a binary file from/to a table with BLOB column
I have create a table with a column of data type BLOB.
I can read/write an IMAGE file from/to the column of the table using:
READ_IMAGE_FILE
WRITE_IMAGE_FILE
How can I do the same for other binary files, e.g. aaaa.zip?There is a package procedure dbms_lob.readblobfromfile to read BLOB's from file.
http://download-east.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_lob.htm#sthref3583
To write a BLOB to file you can use a Java procedure (pre Oracle 9i R2) or utl_file.put_raw (there is no dbms_lob.writelobtofile).

If it's another database then make sure your columns
allow nulls. To check this in the Server Navigator, expand
your DataSource down to the column.
Select the column and view the Is Nullable property
in the Property Sheet
If still no luck, check out a tutorial, like Performing Inserts, ...

In a recent project I've had the need of a Java Swing table with frozen columns.
After a long research at the Swing forum at java.sun.org and google I found out that
1. Currently there is no proper Open Source solution
2. All the postings at sun are good concepts, but far away from solutions
3. The only (for me )acceptable commercial solution is the JCTable from Quest (formerly KGroup)
Since I want to have full control over the source code of the table, I decided to collect all the tips from this forums and write my own table.
Here is the my first result:
http://jroller.com/resources/kriede/CoolTable.java
The main idea is to have two tables, one for the locked columns (=fixed columns = frozen columns) and one for the scrollable columns. With all the tips from this forum it was more or less a puzzle to make it work pretty. The next task will be to provide a JTable-like interface, meaning to write delegate/adapter methods to the API of the two nested JTable instances.The FixedColumnExample from the link that you provided doesn't work with JDK 1.3 or higher.
Anyway, putting a seperate table for the fixed columns into the row header is the first step to solve the problem of fixed columns.
The next problem is to synchonize the scrolling behaviour of the two tables. The FixedColumnExample tries to do it by overwriting the valueChange method (maybe this was working with JDK 1.8), but with JDK 1.2 or higher it is recommended to use ChangeListeners. That's what I am doing, as also described here: http://www.chka.de/swing/components/JScrollPane-bugfix.html.
Another problem is navigation with the tab or arrow keys: The default actions for those events move the selection only within one JTable. It would be nicer, if e.g. the tab key moves the selection within one row across both, the fixed and the scrollable columns.
Those problems and some more are solved in the CoolTable sample:
http://jroller.com/resources/kriede/CoolTable.java

Sparse table with many columns
Hi,
I have a table that contains around 800 columns. The table is a sparse table such that many rows
contain up to 50 populated columns (The others contain NULL).
My questions are:
1. Table that contains many columns can cause a performance problem? Is there an alternative option to
hold table with many columns efficiently?
2. Does a row that contains NULL values consume storage space?
Thanks
dyahav[NULLs Indicate Absence of Value|http://download-west.oracle.com/docs/cd/B14117_01/server.101/b10743/schema.htm#sthref725]
A null is the absence of a value in a column of a row. Nulls indicate missing, unknown, or inapplicable data. A null should not be used to imply any other value, such as zero. A column allows nulls unless a NOT NULL or PRIMARY KEY integrity constraint has been defined for the column, in which case no row can be inserted without a value for that column.
Nulls are stored in the database if they fall between columns with data values. In these cases they require 1 byte to store the length of the column (zero).
Trailing nulls in a row require no storage because a new row header signals that the remaining columns in the previous row are null. For example, if the last three columns of a table are null, no information is stored for those columns. In tables with many columns, the columns more likely to contain nulls should be defined last to conserve disk space.
Most comparisons between nulls and other values are by definition neither true nor false, but unknown. To identify nulls in SQL, use the IS NULL predicate. Use the SQL function NVL to convert nulls to non-null values.
Nulls are not indexed, except when the cluster key column value is null or the index is a bitmap index.>
My guess for efficiently storing this information would be to take any columns that are almost always null and place them at the end of the table definition so they don't consume any space.

Exporting Table with CLOB Columns
Hello All,
I am trying to export table with clob columns with no luck. It errors saying EXP-00011TABLE do not exist.
I can query the table and the owner is same as what i am exporting it from.
Please let me know.An 8.0.6 client definitely changes things. Other posters have already posted links to information on what versions of exp and imp can be used to move data between versions.
I will just add that if you were using a client to do the export then if the client version is less than the target database version you can upgrade the client or better yet if possilbe use the target database export utility to perform the export.
I will not criticize the existance of an 8.0.6 system as we had a parent company dump a brand new 8.0.3 application on us less than two years ago. We have since been allowed to update the database and pro*c modules to 9.2.0.6.
If the target database is really 8.0.3 then I suggest you consider using dbms_metadata to generate the DDL, if needed, and SQLPlus to extact the data into delimited files that you can then reload via sqlldr. This would allow you to move the data with some potential adjustments for any 10g only features in the code.

Bsp table with editable columns
Hi,
I want to create a table with some columns and include check box.
Is it possible?
I want to do this
Table :
Date Time Checkbox Checkbox
Also how can i make the columns editable ?
Thank youhello,
The basic idea would be use ITERATOR class reference in your 'Tavleview' HTMLB element
Iterator class should user interface 'IF_HTMLB_TABLEVIEW_ITERATOR', here you can modify column properties (GET_COLUMN_DEFINITIONS method) and cell properties (RENDER_CELL_START)
For your need:
RENDER_CELL_START method, example coding would be:
CASE p_column_key.
WHEN 'Column name'.
p_replacement_bee = cl_htmlb_checkbox=>factory(
id = p_cell_id
_checked = p_cell_binding
disabled = 'X' ).
ENDCASE.

Pivot table with variables columns
I need a helo to pivot table with variable columns,
I have a pivot table :

SELECT a.*
FROM (SELECT codigo_aluno,nome_aluno , id_curso,dia FROM c_frequencia where dia like '201308%') PIVOT (sum(null) FOR dia IN (
select dia from v_dia_mes )) a
thank youThe correct answer should be "Use the Pivoted Report Region Plugin".
But, as far as I know, nobody has created/posted that type of APEX plugin.
You may have to use a Basic Report (not an IR) so that you can use "Function returning SELECT" for your Source.
You would need two functions:
One that dynamically generates the Column Names
One that dynamically generates the SELECT statement
These should be in a PL/SQL Package so that the later can call the former to ensure that the column data matches the column names.
i.e. -- no 'SELECT *'
