Dynamically create a class based on database tables

I am trying to build a database and tables on the fly, and save to the harddisk(done). Then I need to create a class using the info from the tables on the fly.
For example,
I built a database BANK, and a table Customer,
Customer
ID
Phoneno
Address
Could I create a class named CUSTOMER (table name)
dynamically, and have ID, PHONENO, ADDRESS,as the attributes of the class?
Could anyone help or show the direction?
Cheers.

You could use a HashMap, and use the String keys "Customer", "ID", etc, and if you have primitive values like an int, you just wrap it inside Integer or any of the other wrapper classes, because HashMap only works with objects.
Then you can use an ArrayList to hold all the records (one record is one HashMap as described above).

Tool to create Java Object classes using the Database Tables

Hi,
Is their any tools or utility available to create the Java Object Classes using the Database Tables as input.
Lets Say I am having the Employee, Employee_Salary tables in the Database.The utility has to create the Java Object classes with the relation.
Please Help...
Thx..

Hm, for generating regular Java classes I wouldn't know one from memory. But I suggest you start searching in for example the Eclipse marketspace for a third party plugin that can do it. If all fail, you could always use Hibernate Tools from the Jboss Tools Eclipse plugin set to generate Hibernate/JPA entities and then strip the annotations from them to turn them into regular POJO classes.
How many tables are we talking about anyway? It might be less effort to just create the classes with properties and then use an IDE to generate getters and setters for them.

How to create mass entries in a database table

Hi,
I am going to do a program that can help me to charge registers in a database table. The origin of the registers is an excell file, that contains 39000 entries.
In other programs I use this function: 'ALSM_EXCEL_TO_INTERNAL_TABLE' but this function can only read 9999 registers. So I ask for us if There is another function that can help me. The other possibility that I think is call many times this function but If is possible to find another function, I guess that is better.
Thanks and regards.

Please allow me to translate "charge registers" into "create entries".
This function module works quite simple via the clipboard, you could take the code and create your own version that allows more rows. However there might be a bottleneck at some point due to your local PC power.
You could also store as CSV or TXT and use GUI_UPLOAD function or the "frontend" classes.
For more performant processing the data would need to be transferred to the application server and uploaded from there using OPEN DATASET and so on, please search for more information.

How to generate the java classes of the database tables

Hi,
I am using Sun One 4 update1 CE for generate java classes of tables from an Oracle database. I have got the database schema file. However, when I right clicked on the database schema file, there is no selection for "Generate Java...".
Besides, when I was trying to use database Schema template from the project tab in the explore window by double click on the project, after following all the procedures of inputing the database url, driver, uername, password, and select the table to generate, the following exception came out:

Create a data source and database tables using WSAD

Hi, guys:
the following is from a tutorial:
http://www-106.ibm.com/developerworks/websphere/techjournal/0306_wosnick/wosnick.html
"To create the data source and Cloudscape database tables automatically, right click on the HelloWorldServer in the Servers view, and select the Create tables and data sources menu item. A dialog will then display showing that the data source and database tables were created successfully (Figure 5)."
I am using WSAD 5.0 trial version. I cannot find Create tables and data sources menu item if I right click on the HelloWorldServer in the Servers view. I am wondering if this is because trial version does not have this feature?
regards

This question is a little off topic but you may get a reply. Please note this forum is about Sun's J2EE SDK and its related technologies. You may have better luck posting your question to an IBM specific resource.

How to create a user in SQL database table for FBA in SharePoint 2013

Hi,
I am trying to configure Form Based Authentication on my SharePoint Dev machine. The purpose is to add an external user to a table (using a registration page).The provider used is SQLMembershipProvider.The dev machine is also configured as domain controller
so all users created locally are AD users.
Reference articles that i checked are
Either adding users to the database as a windows user (i.e. under users section in the database). But on my machine, windows user would be same as adding a AD user.
Or by creating a dedicated IIS site for .Net users (after creating a FBA DB using aspnet_sql tool). Right now i have implemented FBA using this method.
Is it possible to add user details in a table of choice and then access that user using people picker? (without any third party tools).
Thanks,
Thomas

Hi,
We can use CreateUserWizard control to achieve it.
Here is a blog for your reference:

Create generic extractor based on 2 tables

hey BI gurus,
I have to create a generic extractor based on these 3 tables:
eban - i need all fields
vttk - i need only 4 fields i.e
                                     route,
                                     tknum,
                                     datbg,
                                     daten
ekbe - budat.
now the problem is thr is no common field between vttk & eban AND vttk & ekbe. but thr is a common field between eban & ekbe.so i can create a view only on these 2 tables but i want 3 tables
how do i proceed???

Hi,
Sometimes, if your application or requirement makes it necessary, you have to create your own function module to extract the data from whatever sap system to bw.
Therefore you normally make a copy of the standard fm 'RSAX_BIW_GET_DATA_SIMPLE'. To make this new function work for you, you have to realize the following.
1.) the fm gets called by the extraction api for at least 2 times. First time is for initialization and from the 2nd time on it is for data extraction.
2.) right after the last data package (somehow you need to make sure that it is the last one) you have to raise the exception no_more_data.

Can I create a view based on two tables that have the same column name?

I have two tables A and B. Each table has 50+ columns.
I want to create a view that includes all the columns in A and all the columns in B. I created a view with a select statement that says
Select A.*, B.*
From A, B
where A.id = B.id
It returns an error because in each table I have a column that keeps track if a record has been changed called Modified_By. That's where it chokes up on I figure. I would like to write the view without explicitly writing each column name from A and B as part of the select statement. The actual select statement works fine and only bombs when trying to turn the select statement into a view.

You will have to type the full column list at least once. You can save a few keystrokes (i.e. alias. on every column) by providing the column names to the CREATE part instead of in the SELECT part. Something like:
SQL> desc t
Name                                      Null?    Type
ID                                                 NUMBER
NAME                                               VARCHAR2(10)
SQL> desc t1
Name                                      Null?    Type
T_ID                                               NUMBER
LOC_ID                                             NUMBER
NAME                                               VARCHAR2(15)
SQL> CREATE VIEW t_v (id, t_name, t_id, loc_id, t1_name) AS
2 SELECT t.*, t1.*
3 FROM t, t1
4 WHERE t.id = t1.t_id;
View created.HTH

How to create af:tree from single database Table

Hi,
i want to create tree Like this: and also we can add node anywhere.
Parent01
----|parent01-child01
--------|parent01-child01-child01
--------|parent01-child01-child02
-------------|parent01-child01-child02-child01
Parent02
----|parent02-child01
----|parent02-child02
--------|parent02-child02-child01
and for this i have created Table like this :
Table name Treetable
NODEID     NUMBER(38,0) --> Primary Key
NODENAME     VARCHAR2(50 BYTE) --> This is the name will display as a node
DESCRIPTION     VARCHAR2(255 BYTE)
ROOTIND     CHAR(1 BYTE) --> to decide root node
SEQUENCENO     NUMBER(38,0)     --> order to display node
PARENTKEY     NUMBER(38,0) -->FK (refering to NODEID(PK) of this table)
But when i am creating tree, its showing root node for each row in the table. but my requirement is: The Row marked as ROOTIND='Y' , show that row only as Root (Example in above tree:Parent01 & Parent02 )
any help highly appreciated :)
Thanks

APEX How do I create a Form based on a Database Table from other schema

My APEX schema is WISEXP. I have a database table that resides in WISDW schema on the same database. I want to create Tabular form based on this table.
I am not able to create a FORM based on the table from WISDW schema. I am able to create a FORM based on SQL though from this table in WISDW schema - but it does not do any action on Update/Insert rows.
Appropriate Synonyms and grants are created. Is there a limitation or am I missing something? Please advise.
thanks
Rupen

If Rupen is using 2.2 or 2.2.1, it is likely he is running into the bug described here: Re: Workspace to Schema Assignments
In that case, it may be a necessary and sufficient workaround to assign the foreign schema to the workspace.

Dynamic Selection Screen based on database seletion

Hi, Gurus:
I just have simple selection screen with a few radio buttons
However, I would like the radio button show up based on database table criterias:
e.g. if there is no data in table1, the radio button 1 will not showing up.
I have used "SELECT * from table..." and check the return value sy-subrc, if it is not equals 4 (4 means no data in the table), then I put the radio button clause there.
however, it does not work this way.
Thanks in advance
Liang

Hi,
This is a duplicate thread, similar kind of thread is already available .....
with the subject : Dynamic calling of radiobuttons
anyways,
possibly you can think of two ways,
say at the maximum the entry in the database table goes to 20 records and you know that it will not go more than that,
then you can create 20 radiobuttons and using at selection-screen output events hide radiobuttons based on the records present.
say only 4 records are present.
so hide 16 radiobuttons and display only 4 of them.
the other way.
say if there can be n number of records and you dont know the maximum number it can reach then
in the initialization event.
create a report at runtime with the parameter statement as radiobutton .
and then call that report in initialization event itself. this will display the dynamically created radiobutton.

Dynamically creating a Record Group based on Previously entered Record Grou

Forms [32 Bit] Version 10.1.2.3.0 (Production)
Hi,
I know how to dynamically create a record group based on a query and putting the code in When new form instance.
My query is. I have a form which has multiple Record Groups and the user wants to dynamically create subsequent groups based on previous groups.
For example
I have a record group with selects a Location,
when the user selects the Location from a list of values
the 2nd record group called 'Cost Centres' will have to filter out only those with the locations selected above.
How can I populate the 2nd record group at run-time when I do not know what site the user will select?
If I simply populate in when new form instance as in location and just select everything, the list of values populates.
CC field is a LIST ITEM and the list style is a POP LIST, it is not required.
I have put the code in the Location field in the when-list-changed trigger.
I am getting this error:
frm-41337: cannot populate the list from the record group
here is the code:
DECLARE
v_recsql Varchar2(1000); -- The SQL for creating the Record Group.
v_recgrp RecordGroup; -- Record Group
v_status Number; -- Return Value of Populate_Group function.
c_where VARCHAR2(1000);
BEGIN
     IF :location = '1' THEN
          c_where := ' substr(cost_centre,1,2) in (''01'',''02'')';
     ELSIF :location = '2' THEN
          c_where := ' substr(cost_centre,1,2) in (''02'',''03'')';
     ELSIF :location   = '3' THEN
          c_where := ' substr(cost_centre,1,2) in (''01'',''11'',''07'')';
               ELSE
          c_where := ' 1=1'; --EVERYTHING
     END IF;
v_recsql := 'SELECT cost_centre, description FROM   cost_centres where '||c_where;
-- Create the Record Group
v_recgrp := CREATE_GROUP_FROM_QUERY('v_recgrp', v_recsql);
IF NOT ID_NULL(v_recgrp)
THEN -- No Error, record group has been successfully created.
-- Populate Record Group
v_status := POPULATE_GROUP('v_recgrp');
IF v_status = 0
THEN -- No Error. Record Group has been Populated.
POPULATE_LIST('block.CC', 'v_recgrp');
END IF; -- IF v_status = 0
-- Delete the Record Group as it is no longer needed.
DELETE_GROUP('v_recgrp');
END IF; -- IF NOT ID_NULL(v_recgrp)
END;thanks for your assistance.

Hi,
Once record status gets change for block you can not populate/repopulate the list item. Keep those list items as non-database item with different names and create different items as database orignal items. Than assign the values in WHEN-LIST-CHANGE trigger to the actual database items.
