Let's get this straight first: You are talking about inserting a row into a database and counting the number of rows in a database table, right?
Or are you talking about a table in a GUI?
inserting row into a database is not a problem..and then..where after i insert the data into the database..i will retrieve the whole database and display it in my TAble in GUI...my problem now is..how i make it to highlight the new insert data in my table?or other way to say,how i highlight my newly insert datarow in my table?

Get rows where the last row finish off

Hi, i have two tables AND would LIKE TO get data BY combining both.
here IS my data
WITH hist AS
SELECT To_Date('4/23/2010','mm/dd/yyyy') dt, 999 alias, 'PROC' dom FROM dual UNION ALL
SELECT To_Date('4/27/2010','mm/dd/yyyy') dt, 999 alias, 'LON' dom FROM dual UNION all
SELECT To_Date('4/1/2010','mm/dd/yyyy') dt, 111 alias, 'SOC' dom FROM dual UNION all
SELECT To_Date('4/10/2010','mm/dd/yyyy') dt, 111 alias, 'NAO' dom FROM dual UNION ALL
SELECT To_Date('3/23/2010','mm/dd/yyyy') dt, 222 alias, 'PSE' dom FROM dual
final AS
SELECT To_Date('2/26/2010','mm/dd/yyyy') dt, 999 alias FROM dual UNION ALL
SELECT To_Date('4/22/2010','mm/dd/yyyy') dt, 999 alias FROM dual UNION all
SELECT To_Date('4/26/2010','mm/dd/yyyy') dt, 999 alias FROM dual UNION ALL
SELECT To_Date('4/30/2010','mm/dd/yyyy') dt, 999 alias FROM dual UNION ALL
SELECT To_Date('2/25/2010','mm/dd/yyyy') dt, 111 alias FROM dual UNION ALL
SELECT To_Date('2/26/2010','mm/dd/yyyy') dt, 222 alias FROM dual UNION ALL
SELECT To_Date('4/22/2010','mm/dd/yyyy') dt, 222 alias FROM dual UNION all
SELECT To_Date('4/26/2010','mm/dd/yyyy') dt, 222 alias FROM dual
the output should be as follow(without the extra blank line of course)
DT           ALIAS   DOM
2/26/2010     999     PROC
4/22/2010     999     PROC
4/26/2010     999     LON
4/30/2010     999     LON
4/27/2010     999     LON
4/23/2010     999     PROC
2/25/2010     111     SOC
4/1/2010     222     SOC
4/10/2010     222     NAO
2/26/2010     222     PSE
4/22/2010     222     PSE
4/26/2010     222     PSEso what i am doing here is as follow, take one row in hist table (4/23) and join with final table and give me all rows in final table
where dt <= to the row in hist table and include the row from hist table.
this logic will give me rows 2/26/2010,4/22/10 4/23/2010
then the second row in hist table (4/27/2010) wiill get all rows
in final table that is <= to the current row and pick up the rows starting from the row > than the last row where the 4/23/2010 finished off
in this case the output will be 4/26/10, 4/27/2010(we need to include row from hist)
since there is no row in hist that is greater than 4/30/2010, this date will still be display and dom column value should be taking from the max date in hist
which is 4/27/2010. see output above
this sound a little confusing to explain but look at output of what to expect as output. the other ids should follow the same logic
can someone help write a query for this? thanks

Frank, thanks again, i ran the query in oracle 11g and oracle 9i. 11g runs ok but 9i doesnt. it looks like the ignore null option is not supported in 9i. That's right: IGNORE NULLS was new in Oracle 10. You should always mention your Oracle version whenever you ask a quiestion, especially if it's as old as Oracle 9.
i will be running this query in 9i. is there any alternative to re-write this query without using last value since ignore null is not supported and the output is not as i expected when i take that keyword out.
i really appreciate your help. please let me know how would i re-write the query. thanksOne work-around is to use LEAD or LAG instead of LAST_VALUE. This means you have to know exactly where (how many rows away) the most recent non-NULL value is, which in turn requires other analytuic funtions, such as ROW_NUMBER, and more sub-queries:

How to get the last row in a resultset or query

Hi All
Say If I have a complex query which returns a resultset say 15 rows. Now I want to limit the output showing only the last row.
How can we do this

Keep in mind Oracle does not keep "row" order as such. Unlike a graphical type db like Access, Oracle will not always give you back the results in order.
Even if you were to use a sequence, your query is never guaranteed to give back the results in the order you are expecting. You must then give an order by statement to all queries expecting the order.
Your definition of last row too is vague - if it is in fact the greatest amount, use the inline view suggestion. If you simply want to see the last inserted row, consider adding a last_update_date column inserting the sysdate (by a trigger perhaps). This would then allow you to see the last inserted row.
Enjoy!

How to get the last row of a database table.

HI ,
I want to get record exactly from the last row of a database table.
How is that possible?

Hi,
To fetch last record from an internal table, just do find the number of records in it and read using index.
DESCRIBE TABLE ITAB LINES L_LINES.
READ TABLE ITAB INDEX L_LINES.
You can also use LOOP .. ENDLOOP but the above method is better (performance wise).
using LOOP .. ENDLOOP.
LOOP AT ITAB.
**do nothing
ENDLOOP.
**process ITAB (Header record of ITAB).
**after ENLOOP, ITAB will have the last record of the internal table.
[here ITAB is internal table as well as header record.]
But what is the requirement?
If you are looking for the current record of an employee then you can use ENDDA = HIGH_DATE.
My advice is to review your requirement again and try to fetch only that record which you need.

Hiding bloc of Lines in a web template in the last row

Hello,
I want to hide a bloc of lines in a web query.
Here I use the table interface with the method
characteristic cell according to the "How to" - paper
(How to hide a column).
Normally , there is no problem to set the tag
'' in the first column of the row, I want to display again.
But the problem is the last row. Here I must close the
tag in the last column of the last row. The effect is
something like a double line at the end of the output.
(I think, I see here another time the first column of
a row, because I cannot close the tag properly)
As a result, I have problems with the print manager, we use to enhance the web printing.
Can someone give me the information, how to close the tag
in a proper way at the last row.
Many thanks for your help.
Regards
Ralph

Hi,
I don't think this is possible. I would try to use c_cell_extend to extend the style of each <td>-Tag with style="visibility:hidden; display:none" This should have the same affect (for all cells which have to be hidden) (depending on your table styles there might be some padding or spacing effects; you have to try this out).

How can I delete the last row of a Matrix

Hi All,
Does anyone know whether deleting the last row of a matrix controlled by a UDO child table gives problems? I have the strange effect that I cannot delete the very last existing row in the matrix, i.e. after updating the delete the last to-be deleted row comes back into my matrix !!
I give you a snippet of my code (function getSelectedRow gives the selected row in the matrix):
==
if (evnt.ItemUID.Equals(ViewConstants.Items.DELETEBUTTON))
if (evnt.EventType == BoEventTypes.et_ITEM_PRESSED)
    if (evnt.BeforeAction)
      form = BusinessOne.Application.Forms.Item(formUID);
      mtx = (Matrix)form.Items.Item(ViewConstants.Items.MATRIX).Specific;
     int numRow = getSelectedRow(mtx);
     if (numRow != -1)
                                        mtx.DeleteRow(numRow);
                                        form.Mode = BoFormMode.fm_UPDATE_MODE;
                                   Item btn = (Item)form.Items.Item(ViewConstants.Items.ADDBUTTON);
                                   btn.Enabled = true;

To find out the last row that is updated in a View Object

Hi OAF Gurus,
I have requirement like,
I have to find out the last row that is updated on a particular View Object and I have send a mail to the users about the change.
JegSAMassMobVOImpl vo = getJegSAMassMobVO1();
JegSAMassMobVO is the View Object Name and it displays certain rows that has already been added to the VO in the Page.
Now the issue is when a user updates a particular row,I have to find which row gets updated and have to send a email to that particular employee about the change.
Just want to know,how to find out the last updated row in a particular VO.
Any Help would be appreciated as this a immediate requirement.
Regards,
Magesh.M.K.
Edited by: user1393742 on May 4, 2011 1:06 AM

Hi Magesh
It shoud be a Advanced table ,so when user will update the row ,the specific row will fire the PPR and on that event u can capture the row using row reference ,this is the sample code below
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
super.processFormRequest(pageContext, webBean); OAApplicationModule am =
(OAApplicationModule)pageContext.getApplicationModule(webBean);
String event = pageContext.getParameter("event");
if ("<ItemPPREventName>").equals(event))
// Get the identifier of the PPR event source row
String rowReference =
pageContext.getParameter(OAWebBeanConstants.EVENT_SOURCE_ROW_REFERENCE);
Serializable[] parameters = { rowReference };
// Pass the rowReference to a "handler" method in the application module.
262
am.invokeMethod("<handleSomeEvent>", parameters);
In your application module's "handler" method, add the following code to access the source row:
OARow row = (OARow)findRowByRef(rowReference);
if (row != null)

Needs help to retrive the last row in a select query without using rownum

Hi ,
i need to retrive the last row from the select sub query without using rownum.
is there any other way to retrive the last row other than the below query.
is that the ROWNUM=1 will always retrive the 1 row of the select query ?
select from*
*(select ename from employee where dept_id=5 order by desc) where rownum=1;*
Please advise.
thanks for your help advance,

you can select the PRIOR values to get the parent details if you want...

I dont know what table names and fields you have but
say you have a table called XYZ which has a primary
key field called keyID.
So in order to get the last row inserted, you could
do something like
Select *
from XYZ
where keyID = (Select MAX(keyID) from XYZ);
Good Luckwhat gubloo said is correct ...But this is all in MS SQL Server I don't know the syntax and key words in MYSQL
This works fine if the emp_id is incremental and of type integer
Query:
select      *
from      employee e, (select max(emp_id) as emp_id from employee) z
where      e.emp_id = z.emp_id
or
select top 1 * from employee order by emp_id descUday

VJ,
Please don't confuse him. If you want to update the thread, let me leave it aside.Coz it shouldn't cause him trouble. Can u check a.length() is correct? it has to be a.length, isn't it?

How to display the last row in a table

I have a table that is constantly updating, and I always want to see the last row. How can I get my table to auto scroll?

Hi žabić,
there is a property called "top left visible row". You can use it to scroll your table.
edit:
Maybe this is not the exact name, but you can see an example here

Using firefox 4.0.1, IBM SVC console internal server, rows with I think form data, the last row is corrupted and overlays a prior row.

IBM SVC console uses websphere. Screen data that is presented in table form last row appears to overwrite the prior row only. In other similar layouts, the last row is cut in half and cannot be seen. The prior version of Firefox 3 (something) did not have this problem. OS Windows XP Pro SP3
Firefox V3.6.17 worked fine

Seeing the same problem using the HMC with FF7 beta.

Insert a button on the last row of a report

Hi all,
my client wants an "add" button on the last row of any report that he has. I can do it easy on the first row (SELECT DECODE(rownum,1,'button','')), but I couldn't find a solution for this situation.
Can anyone help me?
Thanks in advance.

Sorry, but I didn't quite understand the answer. Here's my example, a real one :)
select     "SGP_DIS_ENT_ANO"."SCE_ID" as " ",
     "SGP_ANO_ESC"."SAE_ANO" as "Ano",
     "SGP_CUR"."SCU_DES" as "Curso",
     "SGP_DIS"."SDE_DES" as "Disciplina"
from     "SGP_ANO_ESC" "SGP_ANO_ESC",
     "SGP_EST_ANO" "SGP_EST_ANO",
     "SGP_CUR" "SGP_CUR",
     "SGP_DIS" "SGP_DIS",
     "SGP_DIS_CUR" "SGP_DIS_CUR",
     "SGP_DIS_ENT_ANO" "SGP_DIS_ENT_ANO"
where "SGP_DIS_ENT_ANO"."SDC_ID"="SGP_DIS_CUR"."SDC_ID"
and     "SGP_DIS_CUR"."SDE_ID"="SGP_DIS"."SDE_ID"
and     "SGP_DIS_CUR"."SCU_ID"="SGP_CUR"."SCU_ID"
and     "SGP_DIS_ENT_ANO"."SEA_ID"="SGP_EST_ANO"."SEA_ID"
and     "SGP_EST_ANO"."SAE_ID"="SGP_ANO_ESC"."SAE_ID"
and "SGP_DIS_ENT_ANO"."SEN_ID" = :P19_SEN_ID
Could you help me with it?
Thanks

How to get the last row

I have 10 rows in my table and I have to retrive last row using rownum.
For this I use
SELECT * from <table_name>
where rownum<=10
minus
SELECT * from <table_name>
where rownum<=9
The result is no rows selected
In the same case if I use
SELECT rownum from <table_name>
Where rownum <= 10
minus
SELECT rownum from <table_name>
where rownum <=9
The result is 10
Why this happend.
If the result is 10, then why the row whose rowid is 10 is not retrived

All
Please bear in mind that ROWNUM is an attribute of the query NOT the table. The last row returned by an unORDERed SELECT statement may be the most recently inserted row but is not guaranteed to be so.
The only way of assuring yourself of returning the most recent row is either to timestamp all your tables with a date_created column or to use a primary key with an ascending value.

Need to set the Vissible row count Dynamically

Hi,
   I have requirement where i am supposed to set the Vissible row count for a table dynmaically, depending upon the number of rows in a table.

Or use a calculated attribute.
Create an attribute in the context called calcVisibleRowCount of type integer and make it read only and calculated. Then bind that attribute to the visibleRowCount attribute of your table.
The method for the attribute looks something like this:
(this displays 10 rows per page if more than 10 records in the node, otherwise it displays the same number of rows in the table as in the context)
public int getCalcVisibleRowCount(IPrivateStartsida.ILayoutElement element)
    //@@begin getCalcVisibleRowCount(IPrivateStartsida.ILayoutElement)
          if (wdContext.nodeXXXX().size() > 10) {
               return 10;
          } else {
               return wdContext.nodeXXXX().size();
    //@@end
Note that this attribute is not created in the node that you want to count number of elements in.
