Last row in VB. How?
Sorry,
I know BW but I'm new at VB.
How can I get the number of rows for result area?
numRows = resultArea.Rows gives error
numRows = resultAreas.Rows.Value ??
Please, I think it should be so easy, but I have no idea.
Thanks
Hi Oscar & Joe,
Joe is correct IF there is a range NAMED "resultArea". But, there is not such a range unless you have already created it.
Oscar, your question is answered in this message:

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 thisKeep 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.

How do I create a new row on tab out of the last column, last row?
JDev 11.1.2.1.0.
I've seen a few topics on this but none that I think were really very good solutions.
Use Case:
On tab out of the last column in the last row, a new row should be added to the end of the table. Bonus points for setting the focus to the first <af:inputText> of the newly created row.
Complications:
1. I'm having a heck of a time trying to find a function that returns the column's displayed index. Sadly, <column binding>.getDisplayIndex() returns -1 unless the user has manually re-ordered the column.
2. Value Change Listeners only fire if there is a value change. Guess that means I need to do client/server listeners to check each and every <af:inputText> for a tab press?
3. I'm not even going to get into setting the focus. With all the templates, regions, etc. going on, it's dang near impossible.
Any ideas on how to attack this one?
WillHi,
You will need to use the Run Engine Installation Wizard found on the Tools menu. In addition you need to create a installation set for the operator interface.
Look at Chapter 16 Distrubuting TestStand ( chapter 17 for version 2).
Once you have created your installation, install is on your new system.
The serial number etc is part of the process model. When you run the entry point 'Test UUTs' the PreUUT callback is executed which asks the user for the serial number.
Hope this helps

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 -
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

How to display a empty (non-existing) column and info in LAST row
Hello!
I´m trying to create the code that diplays all authors (author.name), empty COLUMN, NR_OF_BOOK_PER_AUTHOR.
I want the LAST ROW to display: (column1) the word 'Sum:', (column2) nr of authors, (column3) total sum of all books
Headache: How do I display the EMPTY column and how do I get the LAST ROW to display column1) 'Sum:', (column2) nr of authors, (column3) total sum of all books
It should look like this:
AUTHOR EMPTY NR_OF_BOOKS_PER_AUTHOR
I can list all authors and NR_OF_BOOKS_PER_AUTHOR using this code:
SELECT A.NAME, COUNT(B.ROWID)
FROM AUTHOR A, BOOK B
WHERE B.AUTHOR_ID = A.ID
GROUP BY A.NAME
ORDER BY COUNT(B.ROWID)
I can count the numbers of authors (should be displayed in last row column2) using:
SELECT COUNT(name)
FROM author
and I can list the total amount of books (should be displayed in last row column3) using:
SELECT COUNT(title)
FROM book
But I come up short with how to display the EMPTY column and the last row containing (column1) the word 'Sum:', (column2) nr of authors, (column3) total sum of all books
Any suggestions?
Best regards,
DanielI want the LAST ROW to display: (column1) the word 'Sum:', (column2) nr of authors, (column3) total sum of all booksHave a look at GROUP BY with CUBE or ROLLUP.

How do I open numbers on the last row I completed? It always opens on row 890 and I need it to open on 1086.
Here is the filed report.
Bug ID# 9759704
Summary:
Numbers doesn’t open documents in the cell selected when saved
Steps to Reproduce:
Open a Numbers document with about 200 rows in a table.
Set the zoom factor to 150% (default is 100%)
Select the cell A200
Save the document
Close it
Re-open it
Expected Results:
We expect to get the cell A200 selected in the displayed area as it is when the zoom factor is 100.
Actual Results:
In fact, the cell is well selected but the displayed area isn’t the wanted one.
Here it display rows 123 thru 154.
Clearly, the algorithm used to calculate it fails to take care of the zoom factor.
Regression:
None. just wait that Apple Engineers correct their wrong algorithm or work with zoom factor 100.
Notes:
Would be fine to give us the ability to define the zoomfactor of our choice as we may do in Pages which is not restricted to a predefined list of factors.
Would be glad to get feedback from users.
Here,when zoom factor is 150 %, if the displayed area embed rows 180 thru 211 when I save, on re-open it display rows 120 to 152.
120 is 180/1.5
Wish to know if it's the same for you

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;

How to auto scroll a table to last row when using Active Data Service? 11g
Hi all,
Has anyone got any experience with the ADF Active Data Service?
I am using an af:table in combination with the ADF Active Data Service and I want the table to scroll to the latest row when new data arrives.
It is basically a simple setup:
The value attribute of my table points to a bean that extends CollectionModel and implements ActiveDataModel. This works perfectly. A soon as I receive new data in my bean, the table is automatically updated (e.g. a new row is inserted). I use JDev version: 11.1.1.3
The problem is that I can not get the scroll bar to move down to the last row automatically when new data arrives. The auto scroll only works for the client that actually performs a submit. In other words the person that submits the new data, will see his scrollbar move down, this is because I added the following code:
RowKeySet rowkeysset = chatTableBinding.getSelectedRowKeys();
rowkeysset.clear();
rowkeysset.add(getRowKey());
AdfFacesContext.getCurrentInstance().addPartialTarget(this.chatTableBinding);
This does not work for the clients that receive the new data via the Active data model. Apparently the active data service partially refreshes the table, but not in such a way that it sets the selected row to the last row?
My table definition:
<af:table value="#{pageFlowScope.chatBean.instantMessagingChatwindowBean}" var="row"
id="t1" columnStretching="last" rows="10"
styleClass="AFStretchWidth" autoHeightRows="10" contentDelivery="immediate"
horizontalGridVisible="false"
verticalGridVisible="false"
disableColumnReordering="true" displayRow="last"
rowSelection="single"
binding="#{pageFlowScope.chatBean.instantMessagingChatwindowBean.chatTableBinding}"
inlineStyle="height:80px;">
p.s.
The table is used to show incoming chat message.
I am building a chat client (taskflow) in a Webcenter application. The concept is similar of that presented by Lucas Jellemain in his blogpost on building a Google Talk Client http://www.oracle.com/technetwork/articles/jellema-googletalk-094343.htmlDan,
This is a thanks for posting your findings. You saved me quite some time.
<af:selectBooleanCheckbox id="showOnlyActiveSubscriptions" selected="true"
label="Show only active services:"
value="#{servicePortfolioBean.showOnlyActiveSubscriptions}"
autoSubmit="true" />
<af:table binding="#{servicePortfolioBean.serviceTable}" ...
partialTriggers="showOnlyActiveSubscriptions">
Of course, when I add a "ValueChangeListener" to the selectBooleanCheckbox, the PPR stops working. :( I wonder why? -
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 retrivedAll
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.

Adobe form:How to Print last row of body to next page & printing max7 rows?
Hi,
In ADOBE PDF, Design view, for item level data only 7 row or less should appear in first page for following page if rows are greater than 7 if its less than 7 then last row should be on second page. In design page Below Body Row, user details are 'positioned' so they overlap as soon as item level data exceeds 7.
Using a Static PDF, 7.2. I checked with Pagination property of Item level data, its been set to Place:Following previous and After Continue filling parent. Will putting condition using Form Calc would suffice in condition breaks? What would be condition?
Thanks
MohinderHi,
Solved by changing Condition in Table pane, making one row and increasing Header and footer.

How do I remove the last row in a csv data file
I would like to remove the last row of data from a csv file that I have saved. I can identify the start byte of the last row; however, I'm not sure what tool is the best one to remove it. Should I move the EOF? Should I open the file up to that point then save over the old one? Is there another way I don't know about? I am using labview 7.1.
ThanksI would use the Read Text File. You can right-click on it and tell it to read lines. Then Delete From Array. Leave the index and length unwired and it will delete the last item (I noticed your code is removing the second line). Then open the file again set to replace or create and write your data. This method allows you to propagate your errors instead of the Write/Read Spreadsheet File handling the errors for you.
