How can i find Duplicate Rows in forms6i
Hi,
How can i find duplicate rows in multiple record in forms6i.
Thanks
Raghu.KOops, sorry for misreading your question. (However the SQL I gave you above is also very handy, and worth saving.)
Okay, this is off the top of my head and untested, but might just work. Assuming that your data block name is MYBLOCK, and that the item that you want to check for dups on is named MYNUM, create an item-level WHEN-VALIDATE-ITEM trigger with the following code.
declare
l_newest_record number(10) := :system.cursor_record;
l_newest_mynum number(10) := :myblock.mynum;
l_dup_found boolean := false;
begin
-- In this loop, we skip backwards through all new records to look for dups.
while :system.cursor_record > 1 loop
previous_record;
if :system.record_status = 'NEW' then
if :myblock.mynum := l_newest_mynum then
l_dup_found := true;
exit; -- Dup found!
end if;
else
exit; -- We've gone backwards past the first new record.
end if;
end loop;
-- In this loop, we return to the current record.
while :system.cursor_record < l_newest_record loop
next_record;
end loop;
if l_dup_found then
raise duplicate_row_found; -- user-defined exception
end if;
end;
The above code only checks for dups in the new form records. It assumes that a unique constraint in the database will deal with records actually committed.

How do i find duplicates in iPhoto?
i took a ton of photos while in Paris both with my Nikon D7000 and my iPhone I imported them into iPhoto 11 and how they're all jumbled together but I think there are duplicates, how do i find them?
Apply the two fixes below in order as needed:
Fix #1
1 - launch iPhoto with the Command+Option keys held down and rebuild the library.
iPhoto 8 (09) and earlier- run the options indicated
iPhoto 9 (11) and later- run Option #4 to rebuild the database
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager (iPhoto 8 or earlier or IPhoto 11 and later) and launch.
2 - click on the Add Library button and select the library you want to add in the selection window..
3 - Now that the library is listed in the left hand pane of iPLM, click on your library and go to the
File ➙ Rebuild Library (iPhoto 8 or earlier)
or
Library ➙ Rebuild Library (iPhoto 9 or later)
menu option to rebuild the library.
4 - In the next window name the new library and select the location you want it to be placed.
5 - Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments. However, books, calendars, cards and slideshows will be lost. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory. -
Script to find duplicate index and how can we tell if an index is REALLY a duplicate?
Does any one have script to find duplicate index? and how can we tell if an index is REALLY a duplicate?
RahulOne more written by Itzik Ben-Gan
The first query finds exact matches. The indexes must have
the same key columns in the same order, and the same included columns but in any order.
These indexes are sure targets for elimination. The only caution would be to check for index hints.
-- exact duplicates
with indexcols as
select object_id as id, index_id as indid, name,
(select case keyno when 0 then NULL else colid end as [data()]
from sys.sysindexkeys as k
where k.id = i.object_id
and k.indid = i.index_id
order by keyno, colid
for xml path('')) as cols,
(select case keyno when 0 then colid else NULL end as [data()]
from sys.sysindexkeys as k
where k.id = i.object_id
and k.indid = i.index_id
order by colid
for xml path('')) as inc
from sys.indexes as i
select
object_schema_name(c1.id) + '.' + object_name(c1.id) as 'table',
c1.name as 'index',
c2.name as 'exactduplicate'
from indexcols as c1
join indexcols as c2
on c1.id = c2.id
and c1.indid < c2.indid
and c1.cols = c2.cols
and c1.inc = c2.inc;
The second variation of this query finds partial, or duplicate, indexes
that share leading key columns, e.g. Ix1(col1, col2, col3) and Ix2(col1, col2)
would be considered duplicate indexes. This query only examines key columns and does not consider included columns.
These types of indexes are probable dead indexes walking.
-- Overlapping indxes
with indexcols as
select object_id as id, index_id as indid, name,
(select case keyno when 0 then NULL else colid end as [data()]
from sys.sysindexkeys as k
where k.id = i.object_id
and k.indid = i.index_id
order by keyno, colid
for xml path('')) as cols
from sys.indexes as i
select
object_schema_name(c1.id) + '.' + object_name(c1.id) as 'table',
c1.name as 'index',
c2.name as 'partialduplicate'
from indexcols as c1
join indexcols as c2
on c1.id = c2.id
and c1.indid < c2.indid
and (c1.cols like c2.cols + '%'
or c2.cols like c1.cols + '%') ;
Be careful when dropping a partial duplicate index if the two indexes differ greatly in width.
For example, if Ix1 is a very wide index with 12 columns, and Ix2 is a narrow two-column index
that shares the first two columns, you may want to leave Ix2 as a faster, tighter, narrower index.

How to hide the grid lines between two rows in a ALv? Please help!
Hi Experts,
I have a ABAP ALV(reuse alv grid FM) report.
The last field in the ALV is "Description" which can contain data of size more than 130 chars.
Since the max field length in ALV grid is 130 chars hence I am splitting this field value whenever the field length is more than 130 chars.
After splitting I am generating duplicate rows but with different "Description" field values ( each contains the splitted values".
For example:
Name| City | Description |
Hari|HK |Employee responsible for time management |
Hari|HK |and issue resolution |
Now I want to hide the grid line between these two rows
and just for Description field.
In other words I want ALV to display like this:
Name| City | Description |
Hari|HK |Employee responsible for time management |
Hari|HK |and issue resolution |
How can I acheive this?
Please provide some sample code.
Please help. I will be really greatfull to your help.
Thanks
GopalHi Rich,
If that is the case then atleast how can I hide the complete row grid line?
Please give some sample code.
Thanks

When using private browsing to view image results in Safari 5.1.3, only the first two rows of results are visible, the following four or so rows display greyed out place holders, the remainder of the results page is blank, and the safe search button is inoperable. When I turn off private browsing and refresh the page, everything works again.
Anyone else having this problem?I have got the same behaviour after the last Safari Update to 5.1.3. It seems that Safari now handles some scripts in a new way. If you debug the Google Website, you will see, that there is some Javascript Error, that seems to prevent to write into local cache. After some searching I wasn't able to finde a solution for this problem, other then disabling Javascript while private browsing to prevent the script loading. You then are able to use Google with the old layout. The option to disable JavaScript can be found in the Menu "Developer", wich has to be enabled in Safari in the options first.
In my opinion this is a bug that is now occuring, because Apple changed something in private browsing and that has to be fixed by Google now, to run again. Or we will have to wait for 5.1.4, as you can read online Apple will change and bugfix the javascript engine in that version, perhaps this fixes the problem as well. I hope so!
If anyone is in the developer program perhaps you could test this with the beta of 5.1.4 and tell us if it works. -
Grouping of two rows of internal table
Hi all,
I am having a requirement in which I want to group two rows of an internal table and assign a pointer to the two rows.
This pointer variable will then be passed to ALV.
Help reqd.
regards.Hi Gaurav,
Hope the below code helps:
TYPES :BEGIN OF TY_ITAB2,
DATA(400),
END OF TY_ITAB2.
DATA: ITAB3 TYPE TY_ITAB2 OCCURS 0 WITH HEADER LINE
Loop at itab1.
ITAB3-DATA = ITAB1-LABEL.
APPEND ITAB3.
ITAB3-DATA = ITAB1-MATNR.
APPEND ITAB3.
endloop.
or
You can create a deep internal table. You can declare one Column as an internal table and store the NOTES in that Internal table for each row.

How do I find duplicate songs which the latest itunes libary update does not show?
How do you find duplicate songs in itunes which the latest updated version of itunes does not show, where the older version did?
=Downgrading from iTunes 11 to iTunes 10.7=
Try activating the sidebar, menu bar, and status bar and see if this is close enough to the previous version to make you content. It is easier than downgrading and eventually you will be forced to run a newer iTunes unless you have an endless supply of the model computer you currently own.
You may be able to go back with Time Machine but this may involve restoring other items too (https://discussions.apple.com/message/20441404). Alternatively:
Back up your computer first, in case the unexpected happens.
Quit iTunes.
Get iTunes 10.7 from http://support.apple.com/kb/DL1576 or the direct download link at: http://appldnld.apple.com/iTunes10/041-7195.20120912.d3uzQ/iTunes10.7.dmg
Do a few preparatory steps by making sure all iTunes components are not running and cleaning old files. See https://discussions.apple.com/message/20475394. Do steps 3 and 4. Steps 6-8 may be also useful but I don't know if they are essential. Some of the other steps are not necessary, duplicate steps listed later in my post or are perhaps even unhelpful in the process.
Replace the iTunes 11 application with iTunes 10.7. Simply dragging the application to the trash may not work. Lion (OSX 10.7) and newer systems have iTunes integrated into the operating system and deleting is a bit more involved. Two ways to do this are:
1. (Easier) Use the shareware Pacifist utility (http://www.charlessoft.com/) to install iTunes 10.7 including all associated system files. Details at http://forums.macrumors.com/showpost.php?p=16400819&postcount=6
2. (More work) Check this reference on how to delete the iTunes application itself:
Delete iTunes in Mac OS X 10.7 Lion - http://osxdaily.com/2011/09/13/delete-itunes-in-mac-os-x-10-7-lion/
After deleting the application there may be other files that need downgrading too. See the note about error -42408 at the end of this post. You may want to tuck these away somewhere safe until you have completed the installation of iTunes 10.7. I have not tested this but ideally if newer versions are not found then the installer will put in the old versions. This may include these files in /System/Library/PrivateFrameworks/ which apparently get updated by iTunes 11:
AirTrafficHost.framework
CoreFP.framework
DeviceLink.framework
iTunesAccess.framework
MobileDevice.framework
After doing one of the two procedures above you will have to rescue the most recent old iTunes library from your iTunes > Previous Libraries folder. Rename it "iTunes Library.itl" and replace the existing one in the iTunes folder. A newer version of iTunes irreversibly updates your library file so you have to replace it with the old one or you will get an error message. Note, this will revert your library to the version at the time of the upgrade and you will have to update any changes made since. See:
https://discussions.apple.com/message/20401436 - turingtest2 11/2012 post on rebuilding empty/corrupt library from previous iTunes library file after upgrade/crash.
iTunes: How to re-create your iTunes library and playlists - http://support.apple.com/kb/ht1451
Other issues:
- https://discussions.apple.com/message/20432309 - solution to mobile devices saying they need to be restored after downgrading
- If you encounter error -42408:
iTunes: Advanced iTunes Store troubleshooting - http://support.apple.com/kb/TS3297 > Specific Conditions and Alert Messages: (Mac OS X / Windows) - including specific error codes.
Alternatively, check https://discussions.apple.com/message/20441424 which requires you have a Time Machine backup (though possibly if you remove the newer version of these files old ones may be installed with the iTunes 10.7 installer - untested). A variant of this is at: https://discussions.apple.com/message/20448184

How do I find duplicate photos in iPhoto
I have so many duplicates in iPhoto that my library files is way too large by thousands of photos. I need to find a way to weed out duplicate photos. Anyone know how?
Thanks,
BarbWhere are you seeing these duplicates? If you're seeing them from withing the iPhoto window then you can use one of the apps listed below.
If you're seeing those "duplicate" files via the Finder then you don't have duplicates. iPhoto will have a minimum of 2 files in it's lbrary for each file imported. So don't relay on what you see via the Finder regarding duplicates in the iPhoto library.
T
hese applications will identify and help remove duplicate photos from an iPhoto Library:
iPhoto Library Manager - $29.95
Duplicate Annihilator - $7.95 - only app able to detect duplicate thumbnail files or faces files when an iPhoto 8 or earlier library has been imported into another.
PhotoSweeper - $9.95 - This app can search by comparing the image's bitmaps or histograms thus finding duplicates with different file names and dates.
DeCloner - $19.95 - can find duplicates in iPhoto Libraries or in folders on the HD.
DupliFinder - $7 - shows which events the photos are in.
iPhoto AppleScript to Remove Duplicates - Free
Some users have reported that PhotoSweeper did the best in finding all of the dups in their library: i photo has duplicated many photos, how...: Apple Support Communities.
If you have an iPhone and have it set to keep the normal photo when shooting HDR photos the two image files that are created will be duplicates in a manner of speaking (same image) but the only duplicate finder app that detected the iPhone HDR and normal photos as being duplicates was PhotoSweeper. None of the other apps detected those two files as being duplicates as they look for file name as well as other attributes and the two files from the iPhone have different file names.
iPLM, however, is the most versatile and best all around iPhoto utility to have.
