Deleting all the similar records except one

I have a table without a primary/unique key, this table contains too many rows that have the same column values(the row is duplicated), How can I delete all the duplicated rows and keep one copy of this rows?

JDBC Scenario: Delete all the existing records and Insert

Dear All,
Scenario: IDoc to JDBC
PI need to delete all the existing records in the SQL table then need to insert the records.I have created a two statements in the target structure.
Statement1
   -> TableName
       -> action : DELETE
       -> Table : TableName
Statement2
   -> TableName
       -> action : INSERT
       -> Table : TableName
       ->Access
           -> Elements
I am getting below error while try to delete the records in the table.
JDBC message processing failed; reason Error processing request in sax parser: Error when executing statement for table/stored proc. 'Tablename' (structure 'Statement1'): java.sql.SQLException: FATAL ERROR document format: structure 'Statement1', no key element found
Note: we use above structure in the another interface without specifying any Key for Delete operation(Server is same but different database for this two interface) and it works fine. Although the Primary keys has been set in the SQL table i am getting the above error.
let me know what are the setting need to make in PI and SQL DB to achieve this.

The straucture what you have deined for Delete is not correct, you should have key field in statement structure then only you can perform Delete operation.

How to delete all the PSA data in one go

Hello Guys,
I want to clear all the data from all the PSA tables at one shot, how can i do this??
I have tried following things:
1) I have gone to PSA root node and right click and then clicked on delete PSA data, but its showing me all the datasources and when i am executing that, it is deleting one by one(that i means i need to select individual datasource, which i do not want).
2) Above specified step runs RSPSADEL1 in background , so i doubt whether it deletes psa data only or complete Table?
3)I got the info from other posts that there is a fm which is RSATREE_PSA_DELETE_BATCH, but i need to make myself clear whether this fm deletes only data or complete Table?
I am using sap-bw 3.5.
Regards,
Dolly

Hi,
there is one easy way to delete data from PSA .You can create a process chain have one delete data from PSA step where you need to give PSA table name and request older than (no of days before which you want to delete data ).
Execute it and it will delete all the data before specified no of days .You can add multiple PSA tables here and can delete whole data in one go .

Delete all the user connected to one transaction.

During some periods, we need to lock some transaction to avoid user modify data while we are processing some critical jobs.
If the users are yet in the transaction when we lock the transaction they are not removed from the transaction and we need to kill them manually from SM04 transaction in each application server.
I have been trying to adapt the RSM04000_ALV program to do this but i'm stuck with the use of the pooled session.
I guess that the system when you select the session and click on end session, it mark in anyplace something to indicate to the fuction module TH_DELETE_USER that when the option ONLY_POOLED_USER is enable, only that session need to be killed.
Anybody know how this works? someone have a similar fuctionality in you system?

How do I delete all the photos from my camera roll?

I have all the photos/videos saved to Dropbox, now how do I delete all the photos from my iPhone & iPad Camera Roll/Photo Stream? I want to delete all the photos/videos at one time, is this possible?

Connect to you're laptop. If you are using Windows:
Click "File Explorer"
Click "Computer"
Click the iPhone
Find "Camera Rolll"
Select all of the photos and delete them.
For Mac:
No idea how macs work but it should be something like the instructions for Windows :-/
As far as Photo Stream, they will automatically be deleted after 30 days and they do not take up iCloud space so you have nothing to worry about.

Stop making illogical statements and posting multiple times.
READ the article from which this silly statement was posted and follow the detailed (and explicit) instructions.

The album downloaded except one song. It says purchased rather than play and there is no option to try and download the one song that had an error. I deleted the song name from our library, but it still won't let me download. Any advice?

How do I delete just one day in the history that's bookmarked without deleting all the history

Need to know how I can delete a day in safari history without deleting all the history?

You cannot do that in safari on an ipad, It is all or nothing.

When I plug in my iPhone to my mac it doesn't sync the music and when I try to sync the music is says that it is with another library and will delete all the songs on my phone to put the ones from my computer on it.

Whenever I try to sync my phone with my computer it won't automatically sync my new music from my computer to my phone. When i select it to sync it says that it is going to delete all the music off my phone because its already with another device (or something along those lines) but I use my itunes from my computer to my phone. Does anyone know how I can fix this so it will sync. Will all the songs on my phone be on my computer so it won't matter if it deletes them off of my phone?

In the course of your troubleshooting to date, have you worked through the following document?

How can I import all photos from iPhoto and delete all the ones currently on my iPad?

I uploaded all of my iPad's photos to iPhoto('08) thinking it would be easier to delete and organize them. Now that I've done that in iPhoto I need help finding out how to delete all the photos from the iPad and have the iPhoto photos imported from iPhoto back to the iPad.

This workflow may do what you want:
1 - launch iPhoto with the Option key held down and create a new library.
2 - connect the iPad to your Mac with the new library open.
3 - import all of the photos from the iPad into the new library.
4 - select the option to delete all of the photos from the iPad.
5 - disconnect the iPad and delete the new library.
6 - launch iPhoto with the Option key held down and select your original library.
7 - assemble the photos destined for the iPad so you can easily identify them by album or event which you alread have done.
8 - launch iTunes and connect the iPad to your Mac.
9 - go to the photos section for you iPad and synce those particular albums or Events with the iPad.
That will get those specific iPad photos back into the iPad.
