Vertical tables and date tracked fields
We are in process of remodeling our database. We will have true 3rd normal form tables with vertical structure and date tracked fields among many other changes. I'm interested in Toplink's support capability.
We are evaluating using stored procedures to do CRUD operations and use toplink to do only reads. Has anyone used toplink in this type of database model and how is it implemented?
Thanks
Sure. Having your database in 3rd normal form will only make your object model more consistent and more efficient to modify.
TopLink has great stored procedure support and also performs very favourably on reads, so it serves this kind of model quite well. The caveat is that TopLink tends to cache fairly agressively be default. If you are doing writes outside of TopLink then you will need to determine a strategy for refreshing cached objects that may have changed in the db. TopLink does provide a number of ways that you can use to do that, including cache eviction policies, implicit and explicit refreshing, and cache hit disabling when necessary.

I have a question regarding the date tracked fields in HRMS.
If I want to know what changes are made for a person record, How do I know that?
The changes may be anything like position, salary, job, grade, marital status.
How can I know the old value and the new value after the change?if you are modifying any assignment record an additional record will be created in the table per_all_assignments_f for the same assignment id.
Example if the assignment is updated 3 times you can see 3 records created for the same assignment
Thanks

VIew all tables and data in MaxDB
Is there any software that is able to view all the tables and data in the MaxDB instance?
Hello
Assuming, that you are looking for information about the DB's catalog, please consider the catalog functions of JDBC or ODBC.
Surely there exists a lot of free tools, gathering the catalog via JDBC/ODBC of a database.

so plz help wanna just export the data of phone not the creation of table and data ???? or how can i import just the data from this .dmp ??Pl post OS and database versions.
You will likely need to use the IGNORE flag - http://docs.oracle.com/cd/E11882_01/server.112/e22490/original_import.htm#sthref2201
Imp utility (by default) will try and create the table first. Since the table already exists, imp reports an error. Use the IGNORE flag in your imp command to not report such errors.

Purpose of Entry/Check Table and Currency Quantity Fields...!
Hi......!,
I want to know what is the purpose of this Entry/Check Table and Currency Quantity Fields, while creating a table in DDIC .
give me a clear explanation .....!
best answers would be rewarded.
thanks
prasadHi Prasad,
All the Modules in SAP are inter related,
So their Tables also must be related and must be valid
and they are related to foreign key relation ships
and also we can provide the list of input values using search helps
to know what the search helps and check tables are assigned to the particular field they provided the tab
In the currency fields or quanitiy fields we only enter the amount but not the units,
so the units are assigned if we provide the reference field and table , and so that tab is provided to check what are reference fields and tables and also to assign new fields
hope I am clear
Reward if helpful

MDM - Examples needed with Tables and Data
Hi,
I am new to MDM. I just loaded the Console and Data Manager and connected to an MDM server. I am able to create a repository and browse in the Data Manager. However, I want to get some Table examples and data that go along with it. I am looking for a step by step guide to create some good tables and load actual data into it using a flat file or XML.
Any help is greatly appreciated!Hi,
MDM Repository Structure:-
Table Types in MDM Repository
1.Only one main Table.(Default name is Products)
2.Sub Tables
Lookup Sub tables are just one of the powerful ways that MDM enforces Data integrity in an MDM repository.
(Parent - Child Relationships)
3.Object Tables
It is special type of Lookup Subtables.It includes the images ,Sounds,Videos,Binary objects,Text Blocks,Copy Blocks,Text HTMLs and PDFs.You cannot store any object dirctly to the Repository.Instead ,each object is defined or imported into the repository once then linked to a main or subtable field as a lookup into the object table of that type.
[Object Tables eliminate redunt information ,since each object appears only once in the MDM repository even if it is linked in multiple records.]
4.Special Tables
Special Tables include Image variants,Masks,Families,Relationships,Work Flows,Named Searchs,Data Groups and Validation Group Tables.
[Data Groups and Validation Group Tables are does not exist in the MDM Repository.]
5.System Tables
System Table appear under the Admin Node in the console Hierarchy include roles,Users,Connections,Change Tracking,Remote Systems,Portas,Links..etc.
Creating Look up table.
1.Create Lookup Table(Type as Hierarchy,Taxonomy,Qualifier)
2.Add a Field in Main table
3.Set the type(Hierarchy,taxonomy,Qualifier lookup)
4.You need to enter or map the lookup table name and field.
5.When ever u add new record in the Lookuptable,You can able to use that lookup data in the Main Table Record creation.
I donot have software with me ,otherwise i would have given screenshot to u.
For further info, U can refer Console reference Guide.

R/3 tables and data sources
hi guys,
i am trying to find r/3 tables for plant maintainance data sources
and project system data sources
i am trying it out in help.sap.com
i am able to find r/3 tables information for 60% of data sources only
how can i find the exact information of r/3 tables with respect to data sources
i have seen help link for this application components throughly
please suggest me
i will assign pointsHi Selva,
I typically try this:
Goto ROOSOURCE -> Give the datasource name and find out what type of datasource it is. If it is based on view/table then use the table/view. If it is based on function module then you would need to look at the code and find out from which tables the data is extracted.
For fn module:Goto se37 -> Give the fn module name -> Click the "find" button -> give the text as "select". Select the radio button "Main program". It would list all the select statements in the fn module. In teh select statement you can find the name of the table.
Hope this helps.
Bye

Transport client dependent table and data
Hi,
How do you add a client dependent table and the entries inside to a transport?
Please help.
Thanks,

Edited by: Alvaro Tejada Galindo on Feb 20, 2008 4:33 PMHi there!!!
go to Txn SE09, create a request type "Workbench Request".
1 . Go to the Sub task, select the 'Objects' Tab.
2. Enter the Program ID - R3TR
Object - TABU
Object Name - (Your Required Table Name)
3. Now Press the Function Button on the right, Enter the Table Key, which is nothing but the value of the primary key fields of row to be sent, typed as one.
eq. to send material number 1 from MARA in client 100, following would be the table key:
100000000000000000001
where first 3 characters are for the client
and the remaining 18 characters are for the material number.
Another simple method would be to-
1. execute Txn se16 and display the required Table Contents.
2. Select the rows to be sent, by selecting the check boxes corresponding to those rows, and then selecting the Menu Option
Menu->Table Entry -> Transport Entries.
3. Create a request.
the enties would be included in the request.
Hope This solves your Problem. <REMOVED BY MODERATOR>

Hi everybody,
I'm new in SQL Developer and I would like to know if I could use it to export some tables (and the data in them) and import these on another machine (with Windows OS) that has the same versions of Oracle Database (10 G R2) and SQL Developer(last I have found on the Oracle download page).
If this can be done, could you guide me with some steps?
Thanks a lot!
CristinaTo export tables (structure), it is enough to go to the menu Tools > Export and to choose a path and name for the archive, to select the connection and the objects (in the case = TABLES) that will be exported.
How much to the data, I do not know if a skill exists to export all the data of several (or all) of an only time, without having that to make one to one. -
How to ADD reference table and make a field as currency field in dictionary
pls render some info on how to add refernce table and ref field if i want to make an added field as a currency or quantity field...
Hi Kiran,
It sounds like you are creating a "Z" table or structure and have defined a quantity (eg MENGE). But when you run the syntax check, the system is saying you need to define a reference table / field.
Well when you are in SE11, click on the "Currency / Quantity Fields" tab. You will see 2 columns called "Reference Table" and "Reference Field". These 2 columns define the unit of measure for the currency / qty.
If you have defined in your table MENGE and MEINS and the MEINS field is the unit of measure for the MENGE field you should define your fields as such (inthe Currency/Quantity Fields" tab:
Table - ZVBAP
MENGE MENGE_D QUAN ZVBAP MEINS
MEINS MEINS UNIT
Hope this makes sense.
Cheers,
Pat.
