Delete a column from the table

Hi.
I would like to delete a column from a table. I want to drop the table and recreate it later. But this table has a primary key which
is a foreign key of other tables. So after I recreate the table I must recover the relationship of this table and other tables.
How do I get the information about the primary key of this table as a foreign key of other tables from data dictionary?
Thanks in advance

Change the Table Control attributes such that user can only select a single record(row).
Tip to delete a selected record
1) write a module 'Mark' in the PAI as below
PROCESS AFTER INPUT.
MODULE cancel AT EXIT-COMMAND.
LOOP WITH CONTROL table_view.
MODULE read_table_control.
FIELD flag MODULE mark ON INPUT.
ENDLOOP.
MODULE user_command_0100.
2) Module Mark is below.
MODULE mark INPUT.
CHECK flag = 'X'.
x = table_view-top_line + sy-stepl - 1.
Delete itab INDEX x.
ENDMODULE. " mark INPUT
Table_view is the TableControl Name.
'flag' is of type char(1) available in the Internal table which was assigned to the select option in the table control.

Deleting Material Master from the tables

Hello Gurus.
We marked the materials master as deletion. But we want to remove from tables. Can any one please guide me
Thanks
JJ

In a production system is NO OTHER WAY, only archiving.
In a test system you can use MMDE, but keep in mind this erases the material from the material tables, but if a material was used e.g. in a purchase order, then this order will stay in your system.
If you reuse the material number you will then have inconsitencies to old transactional data, which may be pretty disturbing for all others that do tests.

Getting the same columns from the table twice

I have a question.I am trying to join two tables whose structures and te data are as follows.

I would like to get the output as follows.
MOId networkInterfaceMOId networkPort lineInterfaceMOId linePort
Here the MOId is the MOId of the crossConnect.This is equal to the AssociatedMOId of the portAssoc table.The networkIntefaceMOId is the MOId of the portAssoc which is equal to the MOId of the port.The networkPort is the portIndex in the port table and this is the same for lineInterfaceMOId and linePort.i.e, I have to be able to get the moid of tha associated class and the moid and some values of the port which are asociated.Can any one please tell me how to do this.
your help would be greatly appriciated.
Thanks and Regards,
Bhagya

Try this:
select c.MOld, a.MOld as 'networkInterfaceMOld', p.portIndex as 'networkPort', 'lineInterfaceMOld', 'linePort'
from crossConnect c, portAssoc a, Port p
where c.MOid = a.AssociatedMOid
and a.MOid = p.MOid
I'm not quite sure what you mean by "...and this is the same for lineInterfaceMOId and linePort"
but if they are a column in one of your tables, just add it in based on the model above.

Delete a column froma table that is used in multiple interfaces

Is there a way to delete a column from a table where the table is being used in an interface ? The only way I could find so far was to delete the interface, delete the column then recreate the interface.
Otherwise deleting warns that the object is referred to by another object and lists the interfaces.
unfortunately the table in question is being referred to in multiple interfaces, so I'd prefer not to have to recreate all of them.
Many thanks

You can delete all the mappings (source an target) which refer to this column and then physically delete the column.
It's long but maybe better than dropping the whole interfaces using this column.

9999-----------------044-------------9191--------------03/05/1980
9999-----------------055-------------9191--------------03/06/1989
My goal is to delete employee records for those employee which contains multiple values for JOB_NO
equal to 8181, (JOB_NO= 8181) with new start_dateS.
We need to keep only one record for JOB_NO 8181 which contains oldest start_date.
Here is the delete statement for the single record.
delete from emp
where empno = 7777 and job_no = 8181 and start_date in ('03/01/2002','06/24/1996);
So how could I delete thousands records from the table with this logic?
After deleting multiple records table should be as below:
select * from emp;
EMPNO--------DIVISION--------JOB_NO---------START_DATE
1111-----------------011-------------8181--------------04/10/1999
2222-----------------011-------------3131--------------05/11/2005

7777-----------------033-------------8181--------------12/02/1991
9999-----------------044-------------9191--------------03/05/1980
9999-----------------055-------------9191--------------03/06/1989

Here's one way to do it. I think this fits your business rules. At least it matches the output for your first example. It uses an analytic. I just like using them.

Deleting a row from a table containing CLOB as one of the columns

When i delete a row from a table which contains a CLOB (internal clob) i.e. CLOB or BLOB column, Will the CLOB data will also be deleted ? I understand that what exactly stored in the CLOB column is the clob locator which points to the actual data.
So, when I delete this row, the clob locator will be deleted, but will the actual data what this locator is pointing to is also deleted ??? if not what is the process to delete the data the locator is pointing to when the row containing the locator is deleted ? If this is not happening then the actual data might become an orphan data which nobody has access to, will automatic garbage cleaning occurs on a frequent intravels to delete unaddressed data residing on the database server ?
Thanks in advance for the help, can email me at [email protected] alternatively.
Regards,
Srinivasa C.

Michael,
Thanks very much for your inputs, here are the results i got when i tried the way you explained in your answer, the TRUNCATE command made the actual size back to normal, but the delete is not the same, so, how can i delete the data that a particular clob locator may point to ?
truncate would delete all the rows of the table, which might not serve my purpose, i would like to delete a row and also it's associated clob data from the database! is there anyway to do this ?
is there any limitation on the ool_sample size? i am basically a c++ programmer, i am looking for some function like FREE which would free the allocated memory to the clob once the locator is deleted.
your help is greatly appreciated - Thanks!
:-) Srini.

Upon executing I am entering certain cost center ids on the selection screen to delete them from the table.It did not work.
what is it I am missing?
Thanks,

Delete all entries from the following tables - Follow-up Activities (oracle)

Hello,
I performed a homogeneous system copy of our development BW system with the database (oracle 11.2.0.3) from the BW production system!
I already start the oracle database and the SAP system in the target system/server (development BW system) and I´m doing some follow-up activities. One of this activities is (at the system copy guide 6.2.3.2 Activities at Database Level) is to delete all entries from the following tables:
DBSTATHORA, DBSTAIHORA, DBSTATIORA, DBSTATTORA
I tried to delete them using SQL Plus:
sqlplus /nolog
SQL> connect /as sysdba
SQL> delete from DBSTATTORA;
delete from DBSTATTORA
ERROR at line 1:
ORA-00942: table or view does not exist
... and it show me that error message.
This is strange because when I go to transaction SE14 and check the DBSTATTORA I see that table exist and contain a lot of entries!
Why this is happened in SQL Plus!? I´m running the correct SQL statement for doing this type of task or not?
How can I delete the entries of that tables? Can I do that using the transaction SE14?
Can you help me please?
Thank you,
samid raif

Hello
sqlplus /nolog
SQL> connect /as sysdba
SQL> delete from DBSTATTORA;
delete from DBSTATTORA
ERROR at line 1:
ORA-00942: table or view does not exist
It doesn't surprise me as you are not mentioning the schema name here. Instead it should be
delete from SAPSR3.DBSTATTORA;
Assuming the schema owner is SAPSR3. if the owner is different then replace that with the correct one.

How can I delete an item from the main left column of iTunes?

I'd like to delete an item from the main left hand column in iTunes (the column containing the main headings LIBRARY, STORE, SHARED, PLAYLISTS etc etc). Under the first heading 'LIBRARY' appear the items Library, Music, Movies, iTunes U, Books, Apps and Ringtones. I'd like to remove the item "Library" from that list - it appears immediately after the heading "LIBRARY" and serves no purpose whatsoever. (Neither does it appear to cause any harm, I must say, just a nuisance.) This item does not appear in any of the iTunes viewing options or controls lists. Neither does it appear in iTunes in the other accounts on my Mac and I have yet to see it any other iTunes on any other Mac.
I've upgraded since about iTunes 8 assuming the problem would eventually disappear through the upgrades but it hasn’t, even through all the providedupgrade increments available for iTunes.
I'm assuming it's from something I've installed in my main user account at some stage and it entered this item in the iTunes app. But I can't see how to remove it. The only things I can remember installing are "iTunes Batch Column Renamer" and "Join Together", both if which are just Scripts and which I use fairly regularly, but I don't recall either of them installing that particular item.
Is there any folder I can navigate to to edit the list of items in that main left hand column of iTunes?
Many thanks in advance for any help offered.

on second thought, that you have an item "library" is indeed odd - there shouldn't be.
suggest you try removing iTunes completely (click here and follow the instructions), then reinstall it using the standalone installer from here: http://www.apple.com/itunes/download/.
note this will not do anything to your media files, playlists, ratings, etc.
btw, you didn't install any 3rd party tools like this script:
Change Hidden iTunes Preferences v2.4
This application will allow you to invoke hidden iTunes preferences:
Show "Library" playlist
Changing view setting is global
Allow half-stars in ratings
Hide "Ping" buttons
Show/hide arrow links -- to either search the iTunes Store or search your library
Load complete iTunes Store preview before playing
Create playlists for purchased song collections
Play songs while importing or converting
Create file names with track number
Maintain grid view for Search results

I HAVE A SOURCE TABLE WITH 10 RECORDS AND TARGET TABLE 15 RECORDS. MY WUESTION IS USING WITH THE TABLE COMPARISON TRANSFORM I WANT TO DELETE UNMATCHED RECORDS FROM THE TARGET TABLE ??

I HAVE A SOURCE TABLE WITH 10 RECORDS AND TARGET TABLE 15 RECORDS. MY QUESTION IS USING WITH THE TABLE COMPARISON TRANSFORM .I WANT TO DELETE UNMATCHED RECORDS FROM THE TARGET TABLE ?? HOW IT IS ??

Hi Kishore,
First identify deleted records by selecting "Detect deleted rows from comparison table" feature in Table Comparison
Then Use Map Operation with Input row type as "delete" and output row type as "delete" to delete records from target table.

Combining the same column from 2 tables with distinct result.

I have 2 tables with identical name columns. One is current people and the other is historical people. I want a select that returns any name that is in either table. I want each name listed only once. I want to see 1 entry for each name if it is in the current table, the historical table, or both tables. I can easily do a select distinct on each table but how do I join the queries to get 1 result set with no duplicates? The name column is not a key field and I don't want any other columns from either table.

Just a simple UNION:
select name
from current
union
select name
from historical;
