Oracle does not have 'identity' columns.
Oracle sequences are NOT gap free.
Oracle sequences are independent objects and not associated with any other table or object.
If you are wanting a gap-free sequnece of numbers, which is not recommended, you will have to create your own functionality. And that functionality will not be scalable or perform well.

How to use the Columns Hidden | space in the bottom of af:panelCollection?

Hi,experts,
In jdev 11.1.2.3,
I can see a row of Columns Hidden | Columns Frozen in the bottom of component af:panelCollection - pc1 which have an af:table - t1 component inside in designer view,
and can see there is a blank row space only with "|" inside when the page is running.
Now I want to use this blank row space such as to display row numbers for the table, so I set the property for the panelColletion as following source code:
==========================
<af:panelCollection id="pc1" inlineStyle="width:1250px; height:500px;">
<f:facet name="menus"/>
<f:facet name="toolbar"/>
<f:facet name="statusbar">
<af:group id="g4"/>
</f:facet>
<af:table value="#{bindings.TView1.collectionModel}" var="row"
rows="#{bindings.TView1.rangeSize}"
emptyText="#{bindings.TView1.viewable ? 'No data to display.' : 'Access Denied.'}"
fetchSize="#{bindings.TView1.rangeSize}" rowBandingInterval="1"
filterModel="#{bindings.ImplicitViewCriteriaQuery.queryDescriptor}"
queryListener="#{bindings.ImplicitViewCriteriaQuery.processQuery}" filterVisible="false"
varStatus="vs"
selectedRowKeys="#{bindings.TView1.collectionModel.selectedRow}"
selectionListener="#{bindings.TView1.collectionModel.makeCurrent}"
rowSelection="single" id="t1" inlineStyle="font-size:xx-large; font-weight:bolder;">
<af:column sortProperty="#{bindings.TView1.hints.GoodsStatus3.name}" filterable="true"
sortable="true"
headerText="#{bindings.TView1.hints.GoodsStatus3.label}"
id="c42">
<af:outputText value="#{row.GoodsStatus3}" id="ot33"/>
</af:column>
<f:facet name="footer">
<af:group id="g3">
*<af:outputText value="RowsNumber：" id="ot44"/>*
*<af:outputText value="#{bindings.TView1Iterator.estimatedRowCount}"*
id="ot43" partialTriggers="::pc1:t1"/>
</af:group>
</f:facet><f:facet name="detailStamp"/>
</af:table>
</af:panelCollection>
=====================
but when run the page there is no display for the row number, instead on the bottom of the table, there is only a blank row with "|" inside.
How to use the Columns Hidden | Columns Frozen space in the bottom of component af:panelCollection ?
Thanks!

Hi, Arun
It works.
As in my use case, can draw an af:toolbar component into statusbar of Panel Collection facets in Structure view.
There is still a small issue:
cannot see the Columns Hidden|Columns Frozen component in the Structure view,
and if drop more than one af:toolbar into statusbar, the sencond one will fall/wrap into second row, even though there is enough space on the first row (to occupy a second row in statusbar will be a waste of space), and cannot see how to adjust.
Thank you very much!

How to use database look up table function in xsl mapping

Can anybody tell me how to use database look up table function while mapping xsl between 2 nodes.
I have an XML file coming in and depending on one of XML elements we need to decide which further path to take. But, using this XML element, we need to query database table, get metadata and accordingly take appropriate path. I have written lookup function which returns metadata value.
Now, the issue is how do I pass the XML element valu as input to look up function? When I tried to drag it to the input node of lookup function, it throws an error like "Maximum number of parameters exceeded"
Thanks,

If the lookup table is always going to remain the same (e.g. a character generator or something similar) you can place the values in a 2D array constant on your diagram, with the input value as one column, the equivalent as the other. When you need to perform the lookup you use an index array to return all the values in the "input column", search it using "search 1D array" and use the resulting index number to index the other column's data. If the values may change, then it would probably be best to load an array control with your equivalent values from a file.

Reg:How to delete the column in table control also from database table.

Hi Experts,
Once again thank u all for giving the responses.
one more doubt is how to delete the columns of table control and also the record shold delete from ztable.
With Regards,
Saroja.P.

Hi,
If you want to delete the rows in the table control and simultaneously delete it from the database table, then you can implement a 'DELETE' functionality specific to your table control. Have a MARK field (you will find that in the screen attributes of the table control -> give a name for the MARK field, you will find an additional MARK column at the beginning of your table control). You can check whatever rows you want to delete from the table control, call the delete module.
"This portion of code inside the LOOP...ENDLOOP.
IF sy-ucomm eq 'F_DELETE'.
gt_itab2-check = mark. " Store the MARK field status into your internal table's correspoding field 'check'
MODIFY gt_itab INDEX tabcontrol-current_line.
ENDIF.
iF sy-ucomm eq 'DELETE1'.
DELETE gt_itab WHERE check eq 'X'. "Your internal table does not have rows that you want to delete
ENDIF.
Now you can modify your database table using the MODIFY statement.
MODIFY ZDB FROM TABLE gt_itab.

How to add a column in table control

Hi ,
Can any one tell me how to add a column in table control? My requirement is to add two columns ( custom fields ) into table control ( It is a standard program). I have added the column in the table and also in the table control. But when I am running the standard program, The newly added column is not there. But I have added in the perticular screen. Change is not reflected.
Can anyone help me on this please.
Thanks in advance.
Regards,
Lakshmi.

Hi,
Ensure the following :
1. After adjusting the database, you`ll have to use the database utility and activate the table.
2. If you have changed the standard screen, in tcode se80 -- right click on the program and click activate all. This activates all objects related to that program.
Now execute the program.
Reward if helpful.

[HTML DB] How to use the existing database table?

[HTML DB] How to use the existing database table?
I installed Oracle 10g database in Computer A(Windows 2000), and I already create all the tables with data and the data size is about 300MB.
In Computer B(Windows 2000), I installed HTML DB 1.6.
How can I use /get the existing database table (in computer A) for HTML DB?
Could anyone help me on this? I am newbie and I need some detail instructions. or Where can I find the examples.....
Thanks

Well I guess if you wish to retain that architecture, i.e. HTMLDB on one machine and your data on another, you will have to establish database links to access the data. Oracle documentation will describe how to achieve that.

How to find in R/3 System, which FI document is from which external system?

Hi Moderator/ FICO Experts,
How to find in R/3 System, which FI document is from which external system?
In case of different Non-SAP external Systems posting the data to one R/3 System.
Thanks
Chandra

Hi,
That really depends on the interfaces that your external systems are using. Check with your ABAP or BASIS team to see what is the method used for posting those documents and with which parameters is passed. Look at BKPF table (FI header) to see the attributes such as user, document type, reference, etc.

How to find the average of table row values it should display in next row in libwindow/CVI

Hi,
How to find the average of table row values it should display in next row in libwindow/CVI
Please let me know the solution.

There isn't a built-in function to perform calculations on thable cells. What you can do is to retrieve thable cells values and calculate the average by yourself.
To retrieve a bunch of cells in a single instruction you can use GetTableCellRangeVals: prerequisite for this function to work correctly is that cells are all included in a Rect structure (shortly, a rectangle) and are all of the same data type. See the help for the function for some explanations and the link to an example of its usage. In Cell range parameter you can pass VAL_TABLE_ROW_RANGE (row) macro to retrieve an entire row. See here for details.
Once you have retrieved cell values in an array, you can pass it to Mean function to calculate the average.
Proud to use LW/CVI from 3.1 on.

After I restored my ipad I chose itunes restore. now how can I get my info of which is backed up from icloud?.

hi all!
Reseting ipad, we are asked to restore info from icloud or itunes. If we choose icloud, the info will be restored, but the apps on the ipad should be downloaded from app. store! because icloud can't save the applications. and If we choose to restore with itunes, the apps will be loaded quickly ,But still we need our info in icloud. and if we go to icloud backup , from ipad settings, we just have one choice: back up now! that backs up the new info, not our backed up info. but we need our backed up info.
After I restored my ipad I chose itunes restore. now how can I get my info of which is backed up from icloud?

This is called "stealing". You do not have the legal right to give her the music you have in your iTunes library unless you are the copyright holder.
when syncing it it said she had to update her phone software first
That's not quite what it said. Someone should have paid more attention to the great big warning about the possibility of losing data if the phone wasn't backed up.
We cannot find her new photos. Please help and there was 100 new pics. Is there any way we can get them back. I already have the program Asoftech - but it doesnt seem to register the iphone only C and D drive. Please help!
It restored the backup that was made on your computer 6 months ago, which did not contain those photos. You're wasting your time trying to find them on the phone. They don't exist.
Hopefully, your friend syncs her phone to her own computer on a regular basis. She needs to plug her phone into her computer and restore it from her last backup. That will restore it to the state it was in when the backup was made.
She also needs to get in the habit of extracting the photos on a regular basis, like she would from any other digital camera.
