hi thank you!
I change my table Engine under Mysql Query Browser, but Foreign Key settinis not action at all ( thank you you mention the foreign key is ignore), quite stronge for me, I have to drop the table and change the table engine to InnoDB in my create table code and run it under command line client,
now, It work.
are there any different to use command line Client and Mysql Query Brower?
thank you!Not really, other than appearance. But, the "GUI" might let you simply change the type of table on an already created database (I don't know, haven't tried it), unfortunately, that won't activate any foreign keys when changing a MyISAM to InnoDB (although it will destroy keys on an InnoDB when changing to MyISAM), as, like the above quote says, the keys are not only not used, they are not even stored. I.E. MySQL no longer even knows, nor cares, that you even attempted to create a foreign key for that table. So, you must drop and recreate the table, you can't simply "change" it. Although you could change it (if the GUI even does this) and then add the foreign key constraints.

Delete Cascade and Composition problem.

As it's well known into a DB You can have more than one Fk and more than one FK could have Delete cascade set.
A typical situation is an intersection table between 2 tables wich solves a N to M relationship.
In BC4J is impossible to manage that situation because Delete Cascate is related to composition and composition tries to lock the owning entity (JBO-25030) however if we try to get the detail row from a ViewLink the other one is invalid and viceversa.
How can I solve that issue ?
I read the Steve's http://radio.weblogs.com/0118231/stories/2003/01/17/whyDoIGetTheInvalidownerexception but we normaly don't know, at the create monent all values (the user should select them) and then the createAndInitRow is not a good solution.
Could someone help.
TIA
Tullio

I've the same Problem and solved it the following way:
Assuming you have the following VOs:
MasterView1
MasterView2
IntersectionView
and two Associations of the composition type (each with the Cascading Delete Option between them):
Ma1InterAssoc
Ma2InterAssoc
If you first select a row in MasterView1 and in MasterView2 you can create a new Row in IntersectionView as both "owning Entities" now have a valid current row. BC4J automatically creates the keys to the two Master Entities for you in the Intersection Entity.
MasterView1Impl vo1 = getMasterView1();
vo1.selectMyRow(...);
vo1.executeQuery();
vo1.next();
MasterView2Impl vo2 = getMasterView2();
vo2.selectMyRow(...);
vo2.executeQuery();
vo2.next();
IntersectionView detVo = getIntersectionView);
Row detRow = detVo.createRow()
detRow.setValueX(...); // it is important to set at least one value!!
detVo.insertRow(detRow);
This method works well since JDeveloper 9.0.3, but unfortunately it is not officially supported by Oracle, so you do it on your own risk :(
Hope it helps

Migration: sqlserver 2000 to oracle - delete cascade [resolved - tank you]

hi
no problems on migration... but...
in the new oracle database, all foreign keys have the "cascade delete" as default...
but i don't want this default (a stupid human error may be ruinous...)
can somebody explain me how change this default in a "exception thrown"?
maybe with an authomatic sql order????
tank you a lot...

Create Foreign Keys with "ON DELETE CASCADE" option
Just untick the box and remap from the source to the oracle model.
Hope this helps

How do I delete cascade with a PL/SQL procedure?

This script will create a PL/SQL procedure that deletes cascade. This is a post to contribute to the Oracle community. Take the code as is and test it before you use it in production. Make sure this is what you want.
Procedure Delete Cascade (prc_delete_cascade)
Description
=============
The principle is very simple. The procedure uses a table called TO_BE_DELETED to keep a list of records to be deleted. This
table keeps the table name and the rowid of those records that need to be deleted. The procedure also uses a function called
DELETE_BOTT_ROW which takes one record of the table and tries to delete it. If the deletion fails with a foreign key constraint
violation, the function parses the SQL error message (SQLERRM) to get the name of the constraint. With the name of the constraint,
the function finds the name of the child table, all the child records that have references to the parent table primary or unique key,
and the parent key primary or unique key column name. Once the child records of the failed delete are identified, the function takes their table name and rowids
and records them into the TO_BE_DELETED table by inserting records of their table name and their rowids. Al the records inserted also contain the level (which
is 1 for the original records, 2 for child records, 3 for granchild records, etc.) and the sequence number of the order in wich they
are recorded. This way, when the function picks up a record to be deleted, it takes the one with the highest level and the highest
inserted sequence, or the "bottom" record. Once all the child records of the failed delete are appended to the TO_BE_DELETED table, it calls itself
recursevely, and the function takes the record at the "bottom" of the table and tries to delete it. If it succeeds, it calls
itself recursevely to delete the next record. If it fails, it goes and finds the child records as described before and once they are
inserted into the TO_BE_DELETED table, it calls itself again recursevely to try to delete again the "bottom" record. All records
that are successfully deleted are flagged as deleted usig the flag_del column so they are not pickt up again. Once all the (parent,
child, grandchild, etc.) records are deleted, the procedure ends without commiting, giving the option to the user to commit or
rollback deletions. The table TO_BE_DELETED is, at the end of the procedure, a list of all the records that were deleted, including their table names
and the order in with they were deleted. The user then can review its content and decide to commit or rollback.
Restrictions
============
1. Single tables only. The procedure only takes one table name and a WHERE clause to identified the records to be deleted.
2. Single columns only. Ther procedure only works with single-column primary, unique and foreign key constraints.
3. Single schema only.
4. Unpredictable results with circular references.

Interesting.
I see a few areas where this could be useful. Elimiating specific test records from a Test DB for example.
Some comments:
<li>Since this is a recursive logic you must add a stop criteria. In this case I would add a max iteration variable. If that one is reached, raise an error message and let the procedure stop with that error.</li>
<li>The when others exception at the end should be removed completely</li>
<li>The when others exception in the middle should be replaced by a specific exception that handles the -2292 error</li>
<li>A list of tables where no record should be deleted could be usefull. If the logic would encounter such a table, it should also stop. This would be to prevent that data from some system critical tables could be deleted per accident.</li>
<li>The reference from the FK constraint to the PK constraint should include the table name and if possible the owner (as long as you use user_* views the owner is always the same. But we could extend this to the ALL_* views). I never met a system where different tables have the identical FK constraint names, however just make this fool proof.</li>

If you want to preserve the data on the boot drive, you must try to back up now, before you do anything else.
There are several ways to back up a Mac that isn't fully working. You need an external hard drive to hold the backup data.
1. Boot from the Recovery partition or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
2. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

Write a Java program using Apache POI that reads in a tab delimited file and outputs an xls file (in what they call Horrible Spread Sheet Format. Create your tab delimited file and then run your Java program using appropriate OS commands.

This.
Unless you can explain exactly why the destination must be xls and no other format is acceptable, I'm going to close the thread. What is this third party tool? Why can it only read the obsolete xls file format.
I'm going through this thread and rejecting all the responses that attempt a solution that isn't xls.
I'm surprised that the OP thought that simply saving with an xls file extension would cause some magic to happen and produce an actual Excel file.

How to alter the constraint for on delete cascade

Hi Guys,
I have a table which has 5 level of child tables .But all the child tables have the foreign keys without on delete cascade.But I have to delete a data in the parent table .One method I thought to change the child table constraints to ON DELETE CASCADE then delete the record and after that again to change the constraints with out the ON DELETE CASCADE.Please let me know wheather these is possible or not .If not is there any other alternatives to achive this.
Any suggestions would be highly appreciated.
Thanks in advance
Prafulla

I think you need to drop and recreate your FKs.
See my example here.
create table TEST1
id NUMBER(12) not null,
anything VARCHAR2(20)
alter table TEST1
add constraint PK_TEST1 primary key (ID);
create table TEST2
id2 NUMBER(12) not null,
fk1 NUMBER(12),
info VARCHAR2(50)
alter table TEST2
add constraint PK_TEST2 primary key (ID2);
alter table TEST2
add constraint FK_TEST2_TO_TEST1 foreign key (FK1)
references TEST1 (ID);
-- and here is the code when I add on delete cascade for FK
alter table TEST2
drop constraint FK_TEST2_TO_TEST1;
alter table TEST2
add constraint FK_TEST2_TO_TEST1 foreign key (FK1)
references TEST1 (ID) on delete cascade;

Problem in delete folder

Please don't refer me to the innumeras delete folder solutions available in the SDN. None of them has come to my help.
I need to delete a folder. Well, codes are available everywhere, I run it, it successfully deletes the folder specified.
But the requirement is, I need to make a zip of the folder, then I'll delete the original folder. I am pasting the code here. The zip part is working, the delete part is not! if you comment the line calling zip, it deletes the folder, but after zipping, it cannot delete.
Is there some lock present? How to check and remove that? Please help.

Thanks it worked.
The problem was, the folder I was trying to delete had .classpath, .project, .websettings files. It was encountering problem to delete these files because it internally also uses files of same name.
May be that was the reason.
I tried with any other folder, it worked.

Problem in Delete Time Quota Compensation

Hi,
There is a problem in Infotype- 416 (Time Quota Compensation) with subtype - Workmen SL Encashment.
When I click on delete button, it goes in nexr screen - Delete Time Quota Compensation. From here, in Absence quotas, i want to delete 1 line item.
There is a one problem in deleting this.. system shows the message Change before earliest retro. date 01.04.2009 acc. to control rec. to py area WK.
Please let me know, what it is???
Regards..

What is the beginning date of the infotype record you are trying to delete?
Please delete the payroll control record and re-create (by checking my prev message) so that the payroll period and retro period are in line with the start date of the IT.
e.g. if IT record is 01.01.2009 - 31.12.2009 --> So create the payroll record for 01.2009 period and 01.2009 retro period. Make sure status is Rel for correction.
As the infotype you're trying to delete belongs to a prior payroll period, control record acts as a shield to changes on this data since it is already used for a prior payroll calculation.

Before using the above statement do the following,
u201C decalare a temporary table for u2018xkomvu2019 say u2018t_xkomvu2019, and copy the data.
Refresh t_xkomv[].
t_xkomv[] = xkomv[].
Delete t_xkomv where KSCHL <> u2018 u2018.
Delete xkomv where KSCHL = u2018 u2018.

Problem in deleting the orders under Custom category.

Hi friends,
        I am facing some problem in deleting the Orders which were created under custom category. In fact we are creating Intransits under Standard category "EI" as well as Custom Category "ZP". I am able to modify the intransits created under "EI" but when I tried to change or delete the orders created under Category "ZP", I am getting a messag triggered by BAPI as " Order can not be changed". atleast I need to delete the order if change is not possible. I am using the BAPI "BAPI_SLSRVAPS_CREATEINTRANS" to create intransits under "EI" and i am using the same BAPI with BADI implementation to "SAPAPO_DM_PO_CHANGE" to create intransits under "ZP". Based on the condition I am changing the am changing the category from EI to ZP in the BADI.
       I am able to change or delete the orders created under the EI but when I tried to change or delete the orders under ZP its giving me a message as Order can not be changed.
       One more thing is If I go to Tcode /SAPAPO/RLCDEL trying to delete all the orders based on category. I am able to see all the orders under created under EI. If I tried to delete the orders based on Custom category ZI it is giving me the message as "No Orders exists in Live cache". But I am able to see the orders in tcode "SAPAPO/RRP3".
       Can any one help me out in making this done. Please help me out in this.
Thanks & Regards,
Ramana.

Hi Visu,
           I really appreciate your gr8 help. Hope you can understand my problem that I am not a SCM person. Still you are responding to my questions with great patience.
           Here what I found is I found the record in OM19 transaction in the object "/SAPAPO/OM_ORDER_EXT_STR". But the interesting is its giving me the GUID as blank . there is empty value in that field. where as the program "/SAPAPO/OM_DELETE_INCON_ORDERS" is asking for the "order GUID".
         can you help me out in finding the order guid and deleting this order.
Regards,
Ramana.

Problem in deletion of data from DSO

Hi All,
We are facing a problem in deleting data from Data Store Object.I am trying to delete data by using right click option on DSO -->Delete Data.It is saying "The system has not finished loading request no : XYZ".
I have tried to trace that request and found that request is running in background and the related process chain was deleted.Also no jobs of that request are available.
Now i want to delete one field from that particular DSO and it is not allowing because we are unable to delete data.Actually no data is present in Active table but we have data in Change Log table which we are unable to delete.
Thanks in Advance.
Regards,
Jaya.

Hi,
Any way u r deleted that processchain if it is there u can kill that job through process chain by killing that job,if it is not possible
u should ask ur BASIS people in SM50 or SMICM tcode we can kill our job but ask the basis people.
once u deleted that then delete the data in hange log then (other once the data is there through that DTP it will not allow u to delete so u delete the data) then go for deleting that DTP also.
Thanks & regards

Problems to delete big *.tif files

I have problems to delete big *.tif filese.
At first Windows delete it, but if i pressed F5 then the files are not deleted. I have tryed to delete it with and without Shift + Del its always the same.
When i delete this file many times then it would be deleted.
A other Problem with this big files is that windows open a dialogbox and calculate the time that needed to delete the tif file.
But i can wait 2 hours and more, nothing is done by windows. In the dialogbox dosn`t change anything.
Have anyone an Idea?
Thank you in advanced.
Daniel

Hi,
Does it happen to other files, just *.tif files? Generally speaking, When deleting a folder, the calculation time depends on not only the
file size but the file numbers of the folder. So you can delete sub-folders separately.
Also, you can try to use a popular methods to fix the issue. Here is the steps:
1. Right click on the file.
   2. Click Properties
   3. Click
Advanced
   4. Under File Attributes uncheck
Allow this file to have contents indexed in addition to file.
Also, you can take the following steps to fix this issue:
Step 1:
You may try creating a new user profile to see if the same problem occurs. If not then it could be a corruption/permissions problem
of the old user profile.

Step 2:
If the new user account works fine then the previous account was corrupt, you may follow the link given below to fix the corrupt
user profile.
Fix a corrupted user profile

In addition, the issue can be related to third-party components, especially file system filter drivers, such as anti-virus drivers. In this situation,
I suggest you can delete the files on Safe Mode. If on Safe Mode It works fine, you could perform
clean boot to check the result.
Hope it helps.
