How to check if record is being referenced by record in other table

Hi,
I need to check if a record in table A is being referenced.
The method I can come up with is to loop through all FK relations in user_constraints, look up the columns involved in user_cons_columns and then execute some dynamic SQL to test for the existence of records with table A's ID column.
Alternatively I could make all FK relations restricted and try to delete the record in an autonomous transaction. If succesfull rollback, but this seems a bit messy.
Maybe there is a more elegant way?

Hi Ajallen,
the problem is that in some cases it may not be possible to query B as it is in another schema and you don't have select priviliges. When you try to delete a record of A and B has a restricted FK to A then you get:
ORA-02292: integrity constraint (<constraint name>) violated - child record foundSo there is a mechanism at work to check this.

HI
Changes to data within a table can be automatically logged. Such automatic logging of changes is called automatic table history. To turn on logging, tickmark the Log Data Changes check box on the Technical Settings screen
IF THIS IS ALREADY DONE FOR A PARTICULAR TABLE, YOU CAN GET THE RECORD OF CHANGES THAT YOU MADE FOR THAT PARTICULAR TABLE AS EXPLAINED UNDER

How can i fetch records from 3 tables in a single query without using join

Hi.
Can any body please tell me <b>How can i fetch records from 3 tables with a single query without using joins</b>
Thanx
prabhudutta

Hi Prabgudutta,
We can fetch the data by using the views concept.
Go throuth this info we can know the how to create view and same like database table only we can fetch the data.
Views conatin the data at runtime only.
Four different view types are supported. These differ in the
way in which the view is implemented and in the methods
permitted for accessing the view data.
Database views are implemented with an equivalent view on
the database.
Projection views are used to hide fields of a table (only
projection).
Help views can be used as selection method in search helps.
Maintenance views permit you to maintain the data
distributed
on several tables for one application object at one time.
step by step creation of Maintenance view:
With the help of the table maintenance generator, you are able to maintain the ENTRIES of the table in SM30 transaction.
It can be set in transaction SE11 - Tools - Table maintenance generator.
Table maintanance Generator is used to manually input values using transaction sm30
follow below steps
1) go to se11 check table maintanance check box under attributes tab
2) utilities-table maintanance Generator-> create function group and assign it under
function group input box. Also assign authorization group default &NC& .
3) select standard recording routine radio in table table mainitainence generator to move table
contents to quality and production by assigning it to request.
4) select maintaience type as single step.
5) maintainence screen as system generated numbers this dialog box appears when you click on create button
6) save and activate table
One step, two step in Table Maintenance Generator
Single step: Only overview screen is created i.e. the Table Maintenance Program will have only one screen where you can add, delete or edit records.
Two step: Two screens namely the overview screen and Single screen are created. The user can see the key fields in the first screen and can further go on to edit further details.
SM30 is used for table maintenance(addition or deletion of records),
For all the tables in SE11 for which Table maintenance is selected , they can be maintained in SM30
Sm30 is used to maintain the table ,i.e to delete ,insert or modify the field values and all..
It creates the maintenance screen for u for the aprticular table as the maintenance is not allowed for the table..
In the SE11 delivery and maintenance tab, keep the maintenance allowed..
Then come to the SM30 and then enter the table name and press maintain..,
Give the authorization group if necessary and give the function group and then select maintenance type as one step and give the screen numbers as system specified..
Then create,,,
Then u will able to see the maintenance view for the table in which u can able to insert and delete the table values...
We use SM30 transaction for entering values into any DB table.
First we create a table in SE11 and create the table maintenance generator for that Table using (utilities-> table maintenance generator) and create it.
Then it will create a View.
After that from SM30, enter the table name and Maintain, create new entries, change the existing entries for that table.
Hope this resolves your query.
Reward all the helpful answers.

Hi Naren,
First get the index number of the IT_data table and store it in one variable whose declaration like this.
data: tabix type sy-tabix.
while reading the internal table it_data set the tabix variable.
tabix = sy-tabix.
Instead of the above use below one.
Delete it_data-objek
Use the Below statement it will delete the row from the internal table.
Delete it_data-objek index tabix
Thanks,

How to delete a record from BSEG table

Dear Experts,
How to delete a record from BSEG table.
If there possible to delete some records from transparent table ?
Please help.
Regards,
Tan

Hi,
Deleting a record from a standard table can be done only if table maintenance exists - Cehck tcode - SM30. But it is not advisable to delete records, coz the records may be dependent on many other tables. If u delete in a single place, there may be chance that inconsistency in the data happens and hence will affect ur financial statements.
Pls. assign points, if useful

How to check if data is being inserted into table?

Oracle 10.2.0.1.0
I have a long running transaction, an insert based on select running from SQLPLUS. It is running for more than 2 hours as the volume of data is extremely high ( more than 2 million records ).
How do I check:
1) The volume of data that is already inserted?.
This is to make sure the session is not "hung", but is actually inserting records into the table.
Thanks

I have a long running transaction, an insert based on select running from SQLPLUS. It is running for more than 2 hours as the volume of data is extremely high ( more than 2 million records ).
How do I check:
1) The volume of data that is already inserted?.If there is a commit statement then you can directly query the table for number of rows inserted.
This is to make sure the session is not "hung", but is actually inserting records into the table.To confirm if it is running or not you can query dba view like dba_extents for that objects you can look into bytes or blocks which should increase if you query is running.
Hope this helps
