UIX Table - show row indexes of a range

How can I show the row indexes of the actual range in a UIX table. For example when the showed record range is 5-14, I would like to display a column which contains the indexes numbered 0-9.

There's nothing built-in to help, you'll have to wire it up yourself.

Jdev 10.1.2 UIX table double rows

After migrating to JDev 10.1.2 I met such problem!
When I add row to editable UIX table and then try to select another row the row I just added makes double!

Application table shows row partially

We got an application table that shows a row partially hidden due to a very narrow space.

Please help, thanks

In your code you have inlineStyle="height:180%;"
Get rid of that. Never attempt to stretch a component vertically using inlineStyles with %.
Use table properties: autoHeightRows = N and ContentDelivery = immediate, where N = to the number of row tall for the table.

JTable Problem (table does not show rows and columns)

Hi All,
What the table is suppose to do.
- Load information from a database
- put all the values in the first column
- in the second column put combobox (cell editor with numbers 1-12)
- the 3rd column put another combobox for something else
- the 4th column uses checkbox as an edit
The number of rows of the table should be equal to the number of
record from
the database. If not given it default to 20 (poor but ok for this)
The number of columns is 4.
But the table does not show any rows or
column when I put it inside a
JScrollPane (Otherwise it works).
Please help,
thanks in advance.

I hope you don't expect us to read hundreds of lines of unformatted code? Use the "formatting tags" when you post.
Why are you creating your own TableModel? It looks to me like the DefaultTableModel will store you data. Learn how to use JTable with its DefaultTableModel first. Then if you determine that DefaultTableModel doesn't provide the required functionality you can write your own model.

How to get row index in table?

I will show row no in table.
In help,I find a example and follow it,I test:
<bc4j:column attrName="Fdesc">
<columnHeader>
<bc4j:sortableHeader text="rowSetProperty"/>
</columnHeader>
<contents>
<bc4j:input readOnly="true">
<boundAttribute name="text">
<bc4j:rowSetProperty name="estimatedRowCount"/>
</boundAttribute>
</bc4j:input>
</contents>
</bc4j:column>
It's OK! But I couldn't get current row index.
I test:
<bc4j:column attrName="Fdesc">
<columnHeader>
<bc4j:sortableHeader text="rowSetProperty"/>
</columnHeader>
<contents>
<bc4j:input readOnly="true">
<boundAttribute name="text">
<bc4j:rowSetProperty name="currentRowIndex"/>
</boundAttribute>
</bc4j:input>
</contents>
</bc4j:column>
It's error! How can I do?

Thanks
I try:
<bc4j:column attrName="Fdesc">
<columnHeader>
<bc4j:sortableHeader text="Seq No"/>
</columnHeader>
<contents>
<textInput readOnly="true">
<boundAttribute name="text">
<bc4j:rowSetIteratorProperty name="currentRowIndex"/>
</boundAttribute>
</textInput>
</contents>
</bc4j:column>
Nothing be showed in the table cells.
Here, I finished using Javabean:
public class ClsRowIndexBean
private int _counter=0;
public ClsRowIndexBean()
public int getCounter()
return _counter++;
public int getCurrentCounter()
return _counter;
public void setCounter(int counter)
_counter = counter;

How to get selected row index of a Table ?

hi gurus,I'm new to Webdynpro for abap
I'm displaying just Flight details in a Table so
how to get selected row index of a Table and need to be display in Message manager.

Hi,
For getting the row index use the following code.
DATA lo_nd_node TYPE REF TO if_wd_context_node.
DATA lo_el_node TYPE REF TO if_wd_context_element.
DATA index TYPE i.
* navigate from <CONTEXT> to <NODE> via lead selection
lo_nd_node = wd_context->get_child_node( name = wd_this->wdctx_node ).
lo_el_node = lo_nd_node->get_lead_selection( ).
index = lo_el_node->get_index( ).
node is the name of the node which is binded to the table.
For printing the message u can use code wizard.
Press ctrl-F7. Now Select generate message.
IN this select the method REPORT_SUCCESS
In the code now u can give index to Message text Exporting parameter. Comment receiving parameter.
Write the whole code in onLeadSelect of the table.

Pankaj Aggarwal

How to get selected Row Index in a table based ona VO?

Hi All,
I'm writing an ADF form wherein I use a VO based on a SQL query. I'd like to know how to get the index of a selected row. I havea selection Listener in place where I can print the selected Row's data using getSelectedRowData().toString() on the table.
How can I get certain Attributes from this selected row.
One solution I thought of is to get the row index and then read attributes. But I cant seem to figure out how to get rowIndex for a selected row. Any sugestions?
Using JDeveloper 11g.
Thanks
P.

If your selected row is marked as current row you can use
// Get a attribute value of the current row of iterator
DCIteratorBinding iterBind= (DCIteratorBinding)dcBindings.get("testIterator");
String attribute = (String)iterBind.getCurrentRow().getAttribute("field1");Where 'testIterator' is the name of the iterator you use for the table and 'field1' is the name of an attribute you want to get.
Or you can iterate over the selected row keys (even if it's only one):
// get selected Rows of a table 2
for (Object facesRowKey : table.getSelectedRowKeys()) {
table.setRowKey(facesRowKey);
Object o = table.getRowData();
JUCtrlHierNodeBinding rowData = (JUCtrlHierNodeBinding)o;
Row row = rowData.getRow();
TestRow testRow = (TestRow)((DCDataRow)row).getDataProvider() ;
}Where TestRow is the row type of the VO of your table.

How to get row index of data table in the while ValueChangeListener fired?

Hi,
i have a data table in my page, which contains various components like inputText, selectOneChoice in each row.
i am invoking a method ValueChangeListener attribute of the selectOneChoice component. I have given the autoSubmit=true for this component.
<tr:selectOneChoice id="ratingModelType"
value="#{childRatio.ratingModelType}" binding="#{pageManager.form.bindRatioType}"
valueChangeListener="#{pageManager.form.onRatingModelTypeChange}" autoSubmit="true"
contentStyle="width:150px" required="#{!childRatio.disableChildRatioRatingModelType}"
requiredMessageDetail="#{appBundle['error.ratingModelTypeShouldNotBeEmpty']}">
<f:selectItems value="#{pageManager.catalog['Rating Model Type']}" />
<tr:selectOneChoice>In that method i want to fetch the map(with all updated values) relevant to the currently modified row of the table.
Since i am not using the selectionListener or any radio buttons in the page i am not able to get the row index of the table.
somebody please tell me how to get the row index of the table, while ValueChangeListener fired?
Thanks in advance.

How to control "hide/show" in a table on row level

I was trying to implement controlling/rendering of "hide/show" in a table on row level, but no luck. Is is possible to render the "hide/show" in a table based on the row attribute? If the row attribute is "true", then render the "hide/show" at that row; If the row attribute is "false", then not render the "hide/show" for that row. Is this feasible? Thanks.

I think this should be possible, what u need to do is as follows:
1) Add a decode statement to your VO query to get 0/1 based on your condition like
decode('',true,0,1) render_flag
2) In VO attrinute mappings caste this attribute as boolean instead of number.
3) Attach this attribute to render flag of hide/show via SPEL.

Column / Row Spanning in UIX table

Hi There,
Anybody know how to achieve column/row spanning when using the uix databound table?
For example, i would like a table which looked similar to the following:
 | Cell1 | Cell2 | Cell3 |
 | A spanned cell |
 --------------------------Is it also possible to combine this with row spanning in a UIX table and then further combine it with the single-selection bean, producing an output similar to the below (how complex can i make this :)) :
 | Select | Column 1 | Column 2 | Column 3 |
 | | Cell 1 | Cell 2 | Cell 3 |
 | o |---------------------------------
 | | A spanned cell |
 | | Cell 1 | Cell 2 | Cell 3 |
 | o |---------------------------------
 | | A spanned cell |
 -------------------------------------------I guess I should add that both rows on the same select line would come from the same row of the data source.
I get the impression that spanning can be done from looking through the BLAF standards at http://www.oracle.com/technology/tech/blaf/specs/tables.html#banding_group_colrow, although maybe this just related to the table layouts (where spanning of this type is easy enough) and isn't applicable/implemented for the databound table itself?
Anyway, thanks in advance for any help :)
Cheers,
Lee

How to get row index in dynamically populated table?

Hi,
I am following example given in http://balusc.xs4all.nl/srv/dev-jep-dat.html to Dynamically populate datatable. How can I get row index while populating table in populateDynamicDataTable() method
private List myList;
private String[] headers; // Optional.
private HtmlDataTable dynamicDataTable;
// Actions ----------------------------------------------------------
public void loadMyList() {
// Set headers (optional).
headers = new String[] {"header1", "header2", "header3"};
// Set rows. This is a stub example, just do your dynamic thing.
String[] row1 = {"ID1", "Name1", "Value1"};
String[] row2 = {"ID2", "Name2", "Value2"};
String[] row3 = {"ID3", "Name3", "Value3"};
// Convert rows to List and set the List.
myList = new ArrayList();
myList.add(Arrays.asList(row1));
myList.add(Arrays.asList(row2));
myList.add(Arrays.asList(row3));
public void populateDynamicDataTable() {
//*********************** I want current row in this method *************//
// Any columns?
if (myList != null && myList.size() > 0) {
dynamicDataTable = new HtmlDataTable();
// Get amount of columns.
int columns = ((List) myList.get(0)).size();
// Set columns.
for (int i = 0; i < columns; i++) {
// Set header (optional).
UIOutput header = new UIOutput();
header.setValue(headers);
// Set output.
UIOutput output = new UIOutput();
ValueBinding myItem =
FacesContext
.getCurrentInstance()
.getApplication()
.createValueBinding("#{myItem[" + i + "]}");
output.setValueBinding("value", myItem);
// Set column.
UIColumn column = new UIColumn();
column.setHeader(header);
column.getChildren().add(output);
// Add column.
dynamicDataTable.getChildren().add(column);
// Getters ----------------------------------------------------------
public List getMyList() {
return myList;
public HtmlDataTable getDynamicDataTable() {
if (dynamicDataTable == null) {
loadMyList(); // Reload to get most recent data.
populateDynamicDataTable();
return dynamicDataTable;
// Setters ----------------------------------------------------------
public void setMyList(List myList) {
this.myList = myList;
public void setDynamicDataTable(HtmlDataTable dynamicDataTable) {
this.dynamicDataTable = dynamicDataTable;
I have tried dynamicDataTable.getRowIndex, but it returns -1
Is there any other way?
Thanks ,
Chitra.

When you dynamically populate a datatable, you're populating the columns, not the actual rows.
Just add EL to the styleClass attribute, like:styleClass="#{myBean.myTable.rowIndex == 1 ? 'highlightedClass' : 'defaultClass'}"where 'myTable' refers to a HtmlDataTable property in the backing bean.

Display of row index in table footer

Hi,
Row no of first row is generally displayed in the footer of the table as
Row <first row rowno> of <total no of rows>.Eg Row 1 of 10.
Can this be changed to display row no of currently selected row insted of first row?
Thanks in advance,
Apurva.

Hi ,
You would not be able to extend the UI per se..
Instead you can make use of the property "firstVisibleRow" and "visiblerows" .
When a user clicks a button to bring down the entries by one
- increase the firstvisiblerow property by 1
when he wants to move to next page ,
- increase the firstvisiblerow property to firstvisiblerow+visiblerows
Use the table toolbar for scrolling..and placing your elements as it would always be properly aligned to your table..

How to avoid this full table scan (and index FFS) ?

Hi All,
Oracle 11.2 on Linux.
See this query and its plan below
SQL> DELETE
2 FROM TABLEA APE
3 WHERE NOT EXISTS
4 (SELECT 1
5 FROM TABLEB AP
6 WHERE AP.col1 = APE.col1
7 AND AP.col2 = APE.col2
8 AND AP.col3 = APE.col3)
9 AND ROWNUM < 51 ;
50 rows deleted.

| 5 | TABLE ACCESS FULL | TABLEA | 80M| 1991M| | 243K (1)| 00:48:42 |
---------------------------------------------------------------------------------------------------------In both tables, TABLEA and TABLEB, there is index on columns col1-col2-col3 as leading columns (TABLEB has few more columns in the index, but after these 3 columns).
Requirement is, I want to delete first 50 records in TABLEA, which does not exist in TABLEB.
I tried with various hints, but Oracle is always doing a full scan on one of the tables and index FFS on other. In some cases, Oracle did full scan on both tables and then deleted 50 records. Stats is up-to-date. Doing a full scan on tables with 80 million and 47 million rows is a bit too much for deleting 50 rows.
How I can make Oracle do
1) Read TABLEA row-by-row
2) for each row, check if it exists in TABLEB
3) If not exists, then delete row from TABLEA, else continue
4) Stop reading TABLEA after we have deleted 50 records
Thanks in advance

---------------------------------------------------------------------------------------------------------Requirement is, I want to delete first 50 records in TABLEA, which does not exist in TABLEB.
Such requirements usually make me curious - what's special about a randomly selected 50 rows ?
Is this trying to delete the data in batches of 50 rows at a time.
How I can make Oracle do
1) Read TABLEA row-by-row
2) for each row, check if it exists in TABLEB
3) If not exists, then delete row from TABLEA, else continue
4) Stop reading TABLEA after we have deleted 50 records
It look's as if a 'no_unnest' hint in the subquery should do what you want. It should make Oracle run the quey with a FILTER subquery. You could then choose to drive the delete through a tablescan of tableA or an index range scan of the index on tableA. Have you considered the effect of (and requirements relating to) nulls in the three columns of either table ?

Table access by index rowid taking more time

Hi All
I've a query like
update tab1
set col1 = ( select col2 from
tab2
where tab1.id = tab2.id) table 1 has arnd 10,000 rows
table 2 has arnd 1,700,000 rows and has a primay key on column id.
This query is taking around 20 secs to execute. I checked the xplan and most of time taken for table access by index rowid.
Could you please suggest what can be the reason for this. (Can it be the clustering factor or something else)
I checked the stats for the tab2, its just three days old.

Ashwani

If you checked the xplan why haven't you posted it so we can look at it? Then we could see what table is being accessed by index rowid. Presumably it is table 2 but we the plan would eliminate the need to make assumptions.
The clustering factor could be a factor. You haven't told us how table1 is being accessed. All rows are being updated so a full table scann is most likely but again the plan would actually show the access.
Did you query the dictionary to see what the clustering factor is? Post the results of that
SQL> select index_name, leaf_blocks, avg_leaf_blocks_per_key, avg_data_blocks_per_key, clustering_factor, distinct_keys
2 from dba_indexes
3 where owner = 'schema'
4 and index_name in ('index_b','index_a');

Accessing Tables using global index rowid is taking too long.

I am using Oracle 10.2.0.4.0. I am having tables which are ~100+GB in size which is range partitioned on a date column and hash subpartitioned on primary key column. And accessing these tables using global index row id using idex range scan( size of those indexes are ~7+ GB) taking ~5+ mins which results in ~1000 rows as out put. So is this means there is some structural problem with tables/indexes or its something issue at block level? How to dig more into this issue?

So is this means there is some structural problem with tables/indexes or its something issue at block level? How to dig more into this issue?once you get a chance to run the query and collect some diagnostic info, here are the questions that you should ask yourself:
1) where is the 5 mins spent? doing index range scan itself, doing table index access by global rowid, waiting for something, doing something else?
2) how many reads are there and what kind (logical, physical, direct path)? per the entire query and per index range scan
3) is there any aggregation in the query? if there is, then 1000 rows output doesn't mean anything -- you could have to access millions or billions of rows to produce a 1000 row output in an aggregate query
The best tool to answer these questions is dbms_xplan.
Best regards,
Nikolay
