2 TopLink Java Object from Table to be used in single selectOneChoice

Hello everyone, can I ask for help on how to solve my problem....
Here's my scenario, I have 2 tables namely tblCollege and tblCourse, they are related through tblCourse.CollegeCode = tblCollege.Code.
I use the jdeveloper wizard using TopLink -> Java Object from Table to add these table to my project. I created an EJB Data Control so that I can use them to my Userinterface using ADF Faces.
What I really want to do is that I need to have selectOneChoice component displaying:
tblCollege.Name + tblCourse.Name, and it should have a value of tblCollege.Code + tblCourse.Code,
so for example in my
tblCollege:
Code---------Name
1---------------Science
2---------------Music
tblCourse
Code-------Name-----------CollegeCode
1-------------Biology----------1
2-------------Computer-------1
3-------------Guitar------------2
what I want in my selectOneChoice is like this:
value----------display
1-1--------------Science-Biology
1-2--------------Science-Computer
2-3--------------Music-Guitar
I'm a little stuck on how I'm going to that. Thanks.

Bawasi,
I see a couple of angles of attack, but this really depends on the technologies involved. If you are using ADF Bindings in combination with ADF Faces then you need to shape the data at the entity level. If ADF Bindings are no the in equation, you can take a less aggressive approach and shape the data in a managed bean. What is not clear to me is the end-to-end use-case. I see the read-only (i.e. how to get data to the drop box), but I am
not certain what attribute on an entity you are attempting to set. Are you trying to set the course for the current user or for a master schedule? Finally, notice that the final shape of your data set shows a unique combinations, you could increase the performance of your use-case and ease of development simply by denormalizing your schema.

How to create the custom table?

Hi, how to create the custom table and how to integrate the table with defferent R/3?
my requiremnt is i have to create the two tables and those i have to integrate with the existed R/3 and using those R/3 i have to update my custom tables .....can give me some idea?

how to create the custom table
There are two approach in creating a table.
1. Bottom-up approach
2. Top-down approach.
Both are valid and you can choose which approach is suitable for you. I always use the bottom-up approach. Here are the steps to create the tables with this approach.
1. SE11 will take you to the DDIC and enter the name of the new table to be created. Let us say Zname. Click create.
2. Enter the short discription of the table and enter the field of the table. If it is primary key and you have to check the box.
3. Enter the data element and double click it, you will be asked to save and will take you to data element discription page. Enter the short discription of the data element and enter the information of domain like the length of field and type of field.
4. If you wanted to use the existing domain then its fine, or else, you have to create one. Enter the domain name in the data element page and double click it. Page will ask to save and jump to domain creation page.
5. In the domain page, you have to save the information which you have already given in the data elements page and check it. Before going to data element page, you have to activate the domain.
6. Go to data element page and save, check and activate.
7. Go to main table page and save, check, and activate.
8. Also, you have to save the technical settings of the table.
The table is now ready for operation. You can use it in your program or you can use it to enter information.
Check table: It is the table which will have all the information about the Foreign keys which are the primary keys in the check table.
It can be created by creating the foreign key from the main table. Click foreign key in the main table and it will take you to a page which will ask for table name and field to which foreign key relation has to be associated. Enter the information and you can create the check table automatically.
SM30 is used for maintenance of the table, that is to realease the errors occured during the creation of the table.

How to create a temp table in the memory, not in disk?

I am wonderfing how to create a temp table in the memory, not in disk?
thanks,

Thanks for rectifying me Howard.
I just read your full article on this too and its very well explained here:
http://www.dizwell.com/prod/node/357
Few lines from your article
It is true, of course, that since Version 8.0 Oracle has provided the ability to create a Keep Pool in the Buffer Cache, which certainly sounds like it can do the job... especially since that word 'keep' is used again. But a keep pool is merely a segregated part of the buffer cache, into which you direct blocks from particular tables (by creating them, or altering them, with the BUFFER POOL KEEP clause). So you can tuck the blocks from such tables out of the way, into their own part of the buffer cache... but that is not the same thing as guaranteeing they'll stay there. If you over-populate the Keep Pool, then its LRU mechanism will kick in and age its contents out just as efficiently as an unsegregated buffer cache would.
Functionally, therefore, there can be no guarantees. The best you can do is create a sufficiently large Keep Pool, and then choose the tables that will use it with care such that they donâ€™t swamp themselves, and start causing each other to age out back to disk.
Thanks and Regards

How to create a new table based out of old data rows

Hi All,
How to create a new table based out of old data rows. Also how can we find out the DBF for different users in a database?
Saqib

Not very clear what you need. I'll try to interpret...
How to create a new table based out of old data rowsIf this means how to create a table from an existing one, then you can do :
SQL> create table <new table> as select * from <old table>;
if you need a subset of rows you can add a where clause.
how can we find out the DBF for different users in a database?Here I need some more clarification. What do you mean exactly ?

How to create Object!

Hi all,
        Can anyone tell me how to create an object of the class CL_BP_HEAD_CORPACCOUNTDET_CTXT .
Please reply as fast as possible.
Regards,
Vijay

Hi Balasubramanian,
The below steps might help u out.
1.      Call the function Create Object.
You have the following options:
¡        Choose Object ->New () in the main menu (or the pushbutton Create Object ).
¡        Position the cursor on a structure node in the navigation area and choose New () from the context menu.
In this case, there are already entries in the Create Object dialog, corresponding to the position of the cursor in the navigation area.
Integration Builder (Integration Directory): You have positioned the cursor on the Service node of a communication party. If you call the function Create Object from the context menu, there are already entries for the object type Service and the party field.
You cannot create objects of type RFC or IDoc again.
       2.      Enter the required information. Select the object type first and then specify the object key.
An input help is available to help you specify the key values. To call the input help, use the icon . The value selection offered by the input help may depend on which values have already been defined for the other key attributes.
Integration Builder (Integration Repository): The namespace selection depends on the selected software component version.
       3.      To confirm your entries, choose Create.
This calls the object editor for this object. The specifications that you made when you created the object are displayed in the header. You can edit the object further in the work area of the object editor.
Once you have confirmed your entries by choosing Create in the Create Object dialog, you can no longer change the object key.
Reward if helpful.
Thankyou,
Regards.

Question on how to create a pivot table

Hi,
I am trying to create a dynamic pivot table (the number of column and row layers change for each request) and I cannot use a data base structure to back it up.
I thought of doing it through a managed bean but in order to do it I need to know how to create the PivotTableModel.
The pivot table model requires a data source object and I do not know how to create it to support multiple row and column layers.
Is there a default data source object that I can extend, or better yet is there a written example on how to create a pivot table model using a managed bean.
Thanks,

How to create a transparent table(z table) dynamically

Hi,
Can anyone explain me how to create a transparent table(z table) dynamically in the program.
Any function module or suggestions welcome.

Hi Mithun
             we will not create transparent table in the program . you could do it by using native SQL in the ABAP Program . the sample is show in below .
This is a sample that show how to connect to Database directly and can use the native SQL to select , create or delete table.

hi all.
please some body tell me how to create bdc with table control
or suggest any www with screen shots
thanks in advance ,

Hi AParna,
Its very Simple.
ALl you have to do is set up a counter based on the number of lines in the tabke. when the counter reaches the number of lines in the table hit the next page button which is at the top of every screen in SAP.
Please refer to the following BDC program I had developed using Table control,
this is for ME01 transaction.
