Need help regarding updated rows

Dear sir,
need help on this query
how many rows got updated when i execute an update statement

If you are executing update statement from sqlplus session.
Make sure "feedback" is turned on. It'll show numbers of rows updated just after the command;
SQL> update tt1 set col1 = 1;
0 rows updated.
SQL> show feedback
FEEDBACK ON for 1 or more rows
SQL> set feedback off
SQL> update tt1 set col1 = 1;
SQL>Details about this sqlplus system setting:
FEED[BACK] {6|n|OFF|ON}
Display the number of records returned (when rows >= n )
OFF (or n=0) will turn the display off
ON will set n=1

Query regarding updating rows in JTable

Query regarding updating rows in JTable
Hello,
I have a JTable with 6 columns and 1000s of rows (which are data read from flat files)
I can select 1 or more rows and change the values of the
columns. each time I do this I need to update the values
in the flat file.
Currently I assign the updated Jtable values to a vector
Vector rowVector = (Vector)defaultModel.getDataVector();
then I iterate over the vector and compare the values with the (old) data
in the JTable.
            for(int rowCount = 0; rowCount<rowVector.size(); rowCount++){
                Vector v = (Vector)rowVector.elementAt(rowCount);
                    //smsList is the Vector that contains the old JTable values
                    for(int i=0; i<smsList.size(); i++){
                            //If colums values have been changed; add that
                            //vector value to another vector
                            selectedsmsList.add(smsList.get(i));
            for(int i=0; i<selectedsmsList.size(); i++){
                     //Update the values in the flat file
            }This works fine except that it takes ages to iterate over the updated vecor and un-updated,old vector; is there any way to directly get the list of rows that were updated in the jtable; so that I can directly do an I/O operation to update the jtablke values?

Just a suggestion.
You could add a listener and use a vector of booleans to keep track of the rows that have been changed. You could then iterate through this boolean vector and update the changed rows.
See

Don't know whether this will be helpful.

Need help with Pivoting rows to columns

Hi,
I need help with pivoting rows to columns. I know there are other posts regarding this, but my requirement is more complex and harder. So, please give me a solution for this.
There are two tables say Table 1 and Table 2.
Table1
name address email identifier
x e g 1
f s d 2
h e n 3
k l b 4
Table2
identifier TRno zno bzid
1 T11 z11 b11
1 T12 z12 b12
1 T13 z13 b13
2 T21 z21 b21
2 T22 z22 b22
As you can see the identifier is the column that we use to map the two tables. The output should be like below
output
name address email identifier TRno1 zno1 bzid1 TRno2 zno2 bzid2 TRno3 zno3 bzid3
x e g 1 T11 z11 b11 T12 z12 b12 T13 z13 b13
f s d 2 T21 z21 b21 t22 z22 b22
Also we do not know exactly how many TRno's, zno's, etc each value in the identifier will have. There may be only 1 TRNO, zno and bzid, or there may be four.
All the values must be in separate columns, and not be just comma delimitted. There are also other conditions that i have to add to restrict the data.
So, can you please tell me what is should use to get the data in the required format? We are using Oracle 10g. Please let me know if u need any more information

Something like this ?

Dim oOrder As SAPbobsCOM.Documents
        oOrder = oCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oOrders)
        If oOrder.GetByKey(530) Then
            oOrder.Lines.SetCurrentLine(1)
            oOrder.Lines.WarehouseCode = "01"
            If oOrder.Update() <> 0 Then
                MsgBox(oCompany.GetLastErrorDescription)
            End If

Need HELP regarding installinfg CR2008/Visual Advantage

I need help regarding installing CR2008/Visual Advantage. I had the evaluation copy of cr2008. My compnay purchased the CR2008 Visual Advantage. Upon calling your customer service, I was told that I had to UN-install the CR2008 evaluation copy then install the CR2008. I did the unstall HOWEVER, when I try to install the CR2008 that we purchased, i get the following error..HR
HR -2147024770-"c:\program files\business objects enterprise 12.0\win32_x86\REPORTCONVTOOL.DLL FAILED TO REGISTER"..
I get more that just that one...I have received this before and based upon this formum, i have delted the regristry in the following using regedit.exe
HKEY_LOCAL_MACHINE\SOFTWARE\BUSINESS OBJECT ;
HKEY_CURRENT_USER\SOFTWARE\BUSINESS OBJECTS..
Afeter i deleted the keys, I re-boot my pc and try to install the coftware again...BUT I GET THE SAME ERRORS...I have tryied this several times....what am i missing/not doing correctly

Hi Shamish
Actually you were on the right track, i think you just have to increase PSAPTEMP a bit and you will be fine. 358 MB seems just too small, i suggest you increase it to at least 2GB.
1. what will be the difference in use of PSAPUNDO and PSAPTEMP while copy is running. ( i.e. what will be entered in PSAPUNDO and what will be filled in PSAPTEMP.)
PSAPTEMP: is needed for large sort operations, as mentioned when you have a select with an ORDER BY clause, or if you do join two tables. During the client copy some sorting might be needed for special tables (cluster tables) where data is stored sorted.
PSAPUNDO: undo space is only needed for DML (data manipulation), if data is changed undo is generated. This obviously is heavily the case during a client copy.
2. the target client already has a copy taken 1 month before. so I think while importing it first delete existing data and then copies the new one.
So If I first delete the target client and then take import on it; will it have advantage in regards of getiing UNDO or TEMP segments getting filled ?
Deleting the client first might help for the undo problem, but you already solved that. I cannot imagine, it will help for the PSAPTEMP issue. As i said i would just increase PSAPTEMP and restart the copy.
One more add: if you are doing the client copy with parallel processes, this will influence your requirements on temp and undo space, because of the concurrently running processes.
Best regards
Michael

Need Help Regarding Enabling The Matrix

Hi All,
We have got one user form and we have got one choose from list and one matrix, on click of choose from list the value will be displayed in the text box and at the same time matrix should get enabled. But it;s not happening in our case. The value is coming in the text box through choose from list but matrix is not getting enabled. We are able to change the back ground color of the matrix, make first column invisible and all but not able to enable the matrix. We need help regarding this one.
Regards,
Jayanth

Hey first bind the columns of matrix to any user datasource
and then you can enter any thing into your matrix
following code may help
suppose you have one column
oForm = SBO_Application.Forms.Item("URFRM")
oUserDataSource = oForm.DataSources.UserDataSources.Add("URDSName",
SAPbouiCOM.BoDataType.dt_SHORT_TEXT, 20)
oMatrix=oForm.Item("URMATRX")
oMatrix = oItem.Specific
oColumns = oMatrix.Columns
oColumn = oColumns.Item("URCOLName")
oColumn.DataBind.SetBound(True, "", "URDSName")
oMatrix.Addrow()
hope this will help
additionally you can look at this sample

I need help regarding measurement of "time domain parameters of Heart rate variability" using labview.

I need help regarding measurement of "time domain parameters of Heart rate variability" using labview.
I am using Labview 8 ... I need to develop a software to accquire the ECG data (simulated enironment ) and compute the time domain parameters of Heart rate variability like "SDNN, SDANN...etc". Can some 1 plllzzzz help me out.Plzz help me if u can.Thanx in advance.

Hi Andy,
Thanx for responding. The input is from a text file. SDNN, SDANN,etc are the timedomain parameters of heart rate variability.
SDNN: the standard deviation of the NN or RR interval i.e. the square root of variance.
SDANN:the standard deviation of the averageNN interval calculated over short periods, usually 5 min,which is an estimate of the changes in heart rate due tocycles longer than 5 min
SDNN index, the meanof the 5-min standard deviation of the NN intervalcalculated over 24 h,
RMSSD: the square root ofthe mean squared differences of successive NN intervals
NN50: the number of interval differences of successiveNN intervals greater than 50 ms, and
pNN50 the proportionderived by dividing NN50 by the total numberof NN intervals.
The problem is dat I am a fresher to the world of Labview. I have jus recently started working on it. Can u please suggest me some some idea as soon as possible.
As i said I have the ECG data in the form of text files..I need to create sort of GUI to calculate the time domain parmeters....I need help urgently. Plzzz help me if u can. If u have and .vi example to calculate the RR interval plzz send it to me ASAP.
Thanku

Hey Seungly,
I've realized that my computer runs fine UNLESS I turn the AirPort on to connect to the Internet. The moment I click "Turn AirPort On," the "You need to restart your computer" screen immediately pops up. Is there any connection between AirPort and my problem?
That could very easily be the case, a bad Airport card. Look at this recent post:

Does yours say something similar?

Is this the senario that you are talking about?

HT201541 I need help with updating my browser.

I need help with updating my browser. Its telling me that Safari is outdated.

That is a very old version belonging to Snow Leopard. I take it you are not actually running Yosemite.
Upgrading to Yosemite
You can upgrade to Yosemite from Lion or directly from Snow Leopard. Yosemite can be downloaded from the Mac App Store for FREE.
Upgrading to Yosemite
To upgrade to Yosemite you must have Snow Leopard 10.6.8 or Lion installed. Download Yosemite from the App Store. Sign in using your Apple ID. Yosemite is free. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
    OS X Mavericks/Yosemite- System Requirements
    Macs that can be upgraded to OS X Yosemite
         1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
         7. Xserve (Early 2009) - Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
     Are my applications compatible?
         See App Compatibility Table - RoaringApps.
Upgrading to Lion
If your computer does not meet the requirements to install Mavericks, it may still meet the requirements to install Lion.
You can purchase Lion at the Online Apple Store. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
