How can we avoid duplication of records in database while inserting records

Hi,
In my scenerio,while inserting the same records through idoc duplication of records is happening in database.How can i avoid this.

Divya,
First its a wrong data, because you cannot have the same data for any condition. Probably its a data problem. Please check with the datbase team and ask them why is it so? They should handle on their end.
Anyways if the above dont work and if you ahve duplicate records then probably you need to come up with a query using select distinct. If this doesnot work then if the duplicates comes into mapping, you might selecting some fields which are common. So you can use a splitbyvalue(on value change) for those records, so even if there are three records it takes only one record. If you have 4 or 5 common values then you can concat them and then use the splitbyvalue change.
Else an adapter module should help you out in sender comm. channel after picking the records.
For an idea can you rajs response in this thread:

Every time I sync my iCal computer with my iPhone 4 or iPad, duplicate entries are generated on both systems. What am I doing wrong or how can I avoid the duplications?

Every time I sync my iCal on my computer through iTunes with my iPhone 4 or iPad, duplicate entries are generated on both systems. What am I doing wrong or how can I avoid the duplications? I have been doing this for several years and this problem is a more recent issue, like in the last 6 months. I have been deleting the duplicate entries, on both systems, but some duplicates reappear through "general" entries that are connected to the correct color for a Calendar, but not the name. I am going nuts and wasting tons of hours trying to get the 3 calendars to sync without generating duplicate entries.

Choose one of the Calenders on ONE of the computers OR the MobileMe as the Master / correct account.
The REINITAILISE the data of MobileMe within preferences on the computer defining the datatransfer correctly (in the advanced box of preferences). The synchronise iphone contacts and calender directly on-line to MobileMe.
I posted a question on this today, and gave my own reply !

How can i avoid to record vocal memos on itunes?

how can i avoid to record vocal memos on itunes?

Voice memos as in (Voice Recordings?) I'm afraid these automatally are backup to your iTunes music library, when synced to your computer. One way i can suggest keeping them altogether is having a separate folder with them all placed in, and untick the box so they don't play when listening to music and so on.

Hello and welcome to the forum,
Try to use a good microphon, and if possible place it in a 'sound booth', that you can buy or find work flows to create one yourself.

How can i avoid EOFException?

Dear Friends,
here raf is RandomAccessFile
and Record is Object
my doubt is when i execute is code, it was executed. and also it throws EOFException. i know what is the problem(EOF)
how can i avoid this exception ?
please give corrected code..............
boolean _bolVal = true;
while(_bolVal)
try
objectSize = raf.readInt();
System.out.println("The Object Size : " + objectSize);
byte[] byteData = new byte[objectSize];
raf.read(byteData);
ByteArrayInputStream bais = new ByteArrayInputStream(byteData);
ObjectInputStream ois = new ObjectInputStream(bais);
Record auditObject = (Record)ois.readObject();
catch(EOFException e)
_bolVal = false;
e.printStackTrace();
Thank You

Don't read past the end of the file.
If you don't know how long the file is or which is the last record, you can't avoid EOFException, and there's no reason why you should try. That's what it's there for, to tell you that you're reading past the end of the file.

How can i avoid restarting tomcat server when servlet is modified?

please advice me that how can i avoid restarting the tomcat server, whenever a servlet file is modified in my application. is their any way ?

No probs. Here's how I do things...
1. Install tomcat as normal (e.g. I install to C:\Apps\jakarta-tomcat-5.5.4)
2. Create a webapps directory in your eclipse project with the following directory structure
MyEclipseProject
   - src
   - conf
   - webapps
      - MyApplication
         - META-INF
         - WEB-INF
            - classes
            - lib
            - pages3. Set the project's output folder (e.g. bin folder) to webapps/MyApplication/WEB-INF/classes
4. Put all your jar files in the lib directory
5. Put JSPs / HTML in the pages directory (you may also want to create additional directories for TLDs, config files etc)
6. Ensure your web.xml is in the WEB-INF directory
7. Although it isn't essential I create a context.xml file and store it in META-INF, e.g.
<Context reloadable="true">
    
     <WatchedResource>WEB-INF/web.xml</WatchedResource>
     <WatchedResource>WEB-INF/conf/struts/struts-config.xml</WatchedResource>
     <WatchedResource>WEB-INF/conf/struts/tiles-defs.xml</WatchedResource>
     <WatchedResource>WEB-INF/conf/struts/validation.xml</WatchedResource>
</Context>I use this to set monitored resources that will trigger an automatic appliation reload and to configure JAAS (not shown). See the Tomcat documentation for additional information.
8. In the 'conf' directory I create a server.xml file used to configure Tomcat (you can copy the one from your <TOMCAT_HOME>/conf/server.xml).
After copying the file change appBase attribute in the host element to be the full path to the webapps directory. You can also change the HTTP and HTTPS ports if you wish
9. Download and install the Tomcat Launcher plugin from Sysdeo.
10. In Eclipse's Preferences menu you will see a new entry for Tomcat. Click this then
a. Set your Tomcat Version
b. Set your Tomcat Home
c. Set "Context declaration mode" to server.xml
d. Set the configuration file to the full path to your server.xml file created in step 8
On the "Advanced " sub page select all relevant projects to add to the Tomcat classpath
On the "JVM Settings" page add all the jars in your WEB-INF lib directory to the class path
On the "Source Path" page select all relevant projects
Now if you start Tomcat using the Tomcat icon, you will be able to remote debug your application. If you change web.xml (or any other file in your context.xml watched resources) it will automatically reload. Any changes to JSPs will automatically be picked up (providing your tell your browser not to use the page in cache - e.g. CTRL+F5 in IE)
There are some limitations that I'm still working on however. Primarily that I haven't included the Tomcat Manager application in my webapps directory, so Sysdeo cannot perform a reload. This means that if I change a source file, and eclipse auotmatically rebuilds, Tomcat doesn't pick up the change unless I either change a watched resource file (e.g. web.xml) or stop and restart Tomcat.
There's no reason why this can't be fixed, I just haven't got round to it yet.
I'm sure there are lots of other (probably better) ways of achieving the same thing. This was the first method I tried and it worked, so I stuck with it. I'm not a Tomcat config guru and I'm sure other forum users could provide some improvements should they wish.
Post if you get into trouble, however I won't be able to respond until next week.
Cheers,
Steve

I have made a book of my I Photo pictures. In certain layouts there is a textframe. How can I avoid the frame becoming visible in the print if I don't want to write anything? Should I just leave it or should I delete the text "Write your text here" ?

I have made a book of my iPhoto pictures. In certain layouts there is a text frame. How can I avoid the frame becoming visible in the print if I don't want to write anything? Should I just leave it untouched or should I delete the instructing text "Write your text here"?

Most pages have layouts for pictures only or pictures with text boxes. Either select the same layout for that page but the one without the text box or put a space in the text box.
Putting a space in the text box will avoid getting the warning when ordering that there's an unfilled text box in the book. The box will not be visible in the final product. You can and should check the book before ordering by previewing it as described in this Apple document: iPhoto '11: Preview a book, card, or calendar before you order or print it

How can I avoid (on a mac) getting called on Skype...

How can I avoid (on a mac) getting called on Skype when I'm not signed in?
It's really annoying.
I'm not sure if it's supposed to be that way, but suddenly I get the skype-calling-sound, and I have to log into the skype app to abort the call. The persistent calling bastards kept on calling after I aborted the call and left the app, so I ended up muting my speakers for a while. It really shouldn't have to be this troublesome.

That's like asking how many cows can I get into a field. It depends on the size of the field, size of the cows, the terrain of the field, etc. We could use a bit more information on what you're trying to accommplish:
1 - where are the photos being downloaded from.
2 - how big are the photos?
3 - where are you going to put the photos, i.e. into folders, into an iPhoto library?
4 - how big is the hard drive in the Mac Pro and how much free space do you have on it?
etc., etc, etc......

How can i avoid displaying runtime error in intractive report

hi gurus

regars
imran

Hi Imran,
Basically we can have one basic list and 20 interactive lists.
Once when we reached to 20th list then it goes to shortdump.
So, inorder to avoid that we can modify the system field
SY-LSIND.
Just see this example and try this. I hope this will be useful for you.
REPORT ZSAMPLE1111.
data: begin of itab occurs 0,
        matnr like mara-matnr,
        mtart like mara-mtart,
        mbrsh like mara-mbrsh,
        end of itab.
data: begin of jtab occurs 0,
      maktx like makt-maktx,
      spras like makt-spras,
      end of jtab.
select matnr mtart mbrsh into table itab from mara up to 10 rows.
loop at itab.
write:/ itab-matnr, itab-mtart, itab-mbrsh.
hide itab-matnr.
endloop.
at line-selection.
select maktx spras into table jtab from makt where spras = 'EN' .
case sy-lsind.
when '1'.
loop at jtab.
write:/ jtab-maktx, jtab-spras.
endloop.
when '20'.             * changes see here.
sy-lsind = 1.
when others .
write:/ 'name',sy-lsind.
endcase.
I hope this will be helpful for you.

How can I avoid a full scan when ...

Hello
How can I avoid a full scan with I apply the aggregate function "MIN"
SQL> select min(c1) from hh;
   MIN(C1)
         1
Execution Plan
   0      SELECT STATEMENT Optimizer=CHOOSE
   1    0   SORT (AGGREGATE)
   2    1     TABLE ACCESS (FULL) OF 'HH'Regards
James King

The table 'hh' does not have statistics. Assuming that there is an index on the column c1, statistics are computed on the table and its indexes, you may see a
INDEX (FULL SCAN (MIN/MAX)) of the index on column 'c1'.

how can I avoid duplicates on contacts and how do I get contacts created on iPhone/ipad synchronized on my mac? so far it doesn't work correctly, just sometimes. same for icalendar

On your Mac, for duplicates, switching Contacts off then back on in System Preferences > iCloud may prevent duplicates.
On the iPhone / iPad tap Settings > iCloud. Make sure Contacts and Calendars are swtiched on.
Try restarting your Mac and your iOS devices when items won't sync as they should.
To restart an iOS device: Hold the On/Off Sleep/Wake button down until the red slider appears. Slide your finger across the slider to turn off iPhone. To turn iPhone back on, press and hold the On/Off Sleep/Wake button until the Apple logo appears.
