How to configure the schema name dynamically based on user input.

configure the schema name dynamically based on user input.
For ex:
We have two schemas:
Schema1 - base schema having 15 tables.
Schema2 - tables which is specific to modules. Having only 10 tables which is also available in Schema1
Login to application using Schema 1
Access a particlular module and select the country. Here country selection is identified.
Based on the country selection, we need to connect the schema respectively.
If the user selects France --> It should connect Schema1
If the user selects Germeny --> It should connect schema2.
Used: Eclipselink

You may want to have a different persistence unit for each country, then you just need to switch persistence units, and can put the schema in your orm.xml file.
You may also want to investigate EclipseLink multi-tenant support,
http://www.eclipse.org/eclipselink/documentation/2.5/jpa/extensions/a_multitenant.htm
You can the schema in a persistence unit in code using a SessionCustomizer and the tableQualifier.

How to parameterize the schema name in APEX

Hi,
How to parameterize the schema name in APEX , in order to access different tables from the respective schema.
For example:-
select NAME display_value, CODE return_value
from paramSchema.DESC_LIST WHERE SELECTION_FLG = 'Y'
order by 1
in the above code, paramSchema will be replaced with the actual schema name duing runtime. I tried doing so by some hidden fields on page, but it didn't worked out.
I took the schema name from the respective server as per the IPof the server.
stored in a hidden field named as schema.
And replaced the same in place of schema name. But no luck.
select NAME display_value, CODE return_value
from :schema.DESC_LIST WHERE SELECTION_FLG = 'Y'
order by 1
Please help me in shorting it out.
Thanks,
Anuradha

Hi
In order to do that, you would need to use dynamic SQL by changing the report type to PL/SQL Function Body Returning SQL Query and have code along the lines of
DECLARE
l_sql VARCHAR2(32767);
BEGIN
l_sql := 'select NAME display_value, CODE return_value
from '||:schema||'.DESC_LIST WHERE SELECTION_FLG = 'Y'
order by 1';
RETURN l_sql;
END;However, by doing this, you lose alot of flexibility. The other options would be...
To have seperate report regions that are conditional on the value of the variable.
To use a WITH clause at the tope of the query like...
WITH src_data AS
(SELECT * FROM schema1.my_table
WHERE :schema = 'schema1'
UNION ALL
SELECT * FROM schema2.my_table
WHERE :schema = 'schema2')
SELECT *
FROM src_dataOther than that you could look at using synonyms and doing something similar.
Hope this helps.
Cheers

How to Get the schema name that contains the current procedure?

I have try select sys_context( 'userenv', 'current_schema' ) from dual; but it returns the schema name of the login user. How to return the schema name of the procedure instead? For example, procedure A is in ControlDB, and I login as sys, when query procedure A it should return ControlDB instead of sys.
I have searched in Google but no luck to find the answer so far, please help. Thank you

It works!
I am quite confused now. I did try to use select username from user_users in GetSchemaName procedure, but it always return the login user instead of the owner of the procedure. Why it return the procedure owner if I put the query inside a function then call it from the procedure?
Is it because when the login user call the procedure and the procedure call the function, it's the procedure owner is calling the function so the user_users return the user that is calling it which is the procedure owner. And if the query is directly put inside the procedure, when the login user call the procedure, user_users return the login user directly? Does it imply that if the procedure call any function or other procedures etc, it would be the procedure's owner calling them instead of the login user?
(sys_context works as well if I move the query into the function then call the function from the procedure)

You cannot add columns dynamically. But you can define a maximum number of numbers and then hide unused columns in your form useing SET_ITEM_PROPERTY(..,VISIBLE, PROPERTY_FALSE);

How to pass the table name dynamically in xml parsing

Hi All,
I have created one procedure for parsing xml file which is working perfectly.
FORALL i IN t_tab.first .. t_tab.last
         INSERT INTO Test_AP VALUES t_tab(i);Now I want to put the table name dynamically+. For that I have added one query and modify above code as follow:-
I have already declare dml_str varchar2(800) in declaration part.
Query is as follows:-
select table_name into tab_name from VERSION_DETAILS where SUBVERSION_NO=abc; -- here abc is variable name which contains values.
FORALL i IN t_tab.first .. t_tab.last
          dml_str := 'INSERT INTO ' || tab_name || ' values :vals';
          EXECUTE IMMEDIATE dml_str USING t_tab(i);But it's not working. How I will resolve this or through which way I achieved the intended results. Anyone can guide me on this matter.
Thanks in advance for your help...

Hi,
But it's not working.Don't you think it would help to give the error message?
Put the assignment before FORALL.
FORALL only accepts one subsequent DML statement (static or dynamic SQL) :
dml_str := 'INSERT INTO ' || tab_name || ' values :vals';
FORALL i IN t_tab.first .. t_tab.last
EXECUTE IMMEDIATE dml_str USING t_tab(i);

How to determine the schema name from stored function or procedure

Hi all
I need to find the way to determine the name of shema in which the given stored procedure residing. This SP is created with AUTHID CURRENT_USER what means that expression like SYS_CONTEXT('USERENV','CURRENT_USER') or SYS_CONTEXT('USERENV','CURRENT_SCHEMA') will be return the name of user or schema of user which calls given SP.
can somebody help me?

What is the problem you are trying to solve?
Presumably, when you're creating a stored procedure, you know what schema owns it. So it's pretty trivial to simply create a local variable L_OWNER in your procedure, assign it the value of the schema owner, and then use that owner. Most people don't really need to figure out at runtime what they already knew at compile time.
Barring that, you could inspect the data dictionary as user130038 suggested. That requires that you know the name of the procedure (which would likely also have to be a local variable that is initialized to a hard-coded value. And if there are multiple users that own procedures with the same name, it may not be reliable.
Inspecting the call stack is the most reliable and dynamic approach. But it is also the most costly in terms or runtime performance and in terms of code complexity.

How to read data from a website based on user inputs through java programmi

Hi
I want to get information from a website based on some inputs that I have. The inputs change everytime and based on them, different output is expected. How do I go about with it? Please advice...
Will data mining help in this? or is it used only for analysis and predictions?

you can get the webpage you need very simply like this :
Test.java
public class Test{
          public static void main(String[] args) {
               URLClient client = new URLClient();
                        // URL of a webpage

                                        String line = null;
                                        while ((line = reader.readLine()) != null)

How to change the portal role presentation based on users BW authorization?

Hello,
I have created 3 BW Roles, each one contains an iView with a certain report.
For simplicity let's name the Roles A,B,C and assume that in order to see the proper report the user needs to be assigned to the matching group (A,B,C) at the BW side.
I have imported these 3 roles to the portal as worksets, created new pcd role, placed these 3 worksets inside the new role and assigned this role to a certain group of users in the portal (these users are ABAP users so they are the same at the BW side as well).
What I would like to do is this: I would like that each user that I have assigned this new role to will see only the worksets that he/she allowed to see based on it's BW authorization. Meaning, if I have been assigned roles A and B at the BW I will see only worksets A and B inside the role.
The problem is this: From the portal I cannot assign the users to the BW groups and from BW I cannot control pcd roles so this kind of change requires me to make two modifications: One for authorization from the BW and one for presentation from the portal. I would like to manage it just from one place, either from the BW or from the portal, I don't care.
How can I achieve this?

I think I have found a solution: Export it as a role instead of a workset and do one to one assignments with the BW groups.

Are you saying you are not able to create an object by value (select: statement) as sysdate and put it onto the headers of your report? You can use the add_months() function on the object to add the numbers of months you wish.

How to use the column names generated from Dynamic SQL

Hi,
I have a problem with Dynamic SQL.
I have written an SQL which will dynamically generate the Select statement with from and where clause in it.
But that select statement when executed will get me hundreds of rows and i want to insert each row separately into one more table.
For that i have used a ref cursor to open and insert the table.
In the select list the column names will also be as follows: COLUMN1, COLUMN2, COLUMN3,....COLUMNn
Please find below the sample code:
TYPE ref_csr IS REF CURSOR;
insert_csr ref_csr;
v_select VARCHAR2 (4000) := NULL;
v_table VARCHAR2 (4000) := NULL;
v_where VARCHAR2 (4000) := NULL;
v_ins_tab VARCHAR2 (4000) := NULL;
v_insert VARCHAR2 (4000) := NULL;
v_ins_query VARCHAR2 (4000) := NULL;
OPEN insert_csr FOR CASE
WHEN v_where IS NOT NULL
THEN 'SELECT '
|| v_select
|| ' FROM '
|| v_table
|| v_where
|| ';'
ELSE 'SELECT ' || v_select || ' FROM ' || v_table || ';'
END;
LOOP
v_ins_query :=
'INSERT INTO '
|| v_ins_tab
|| '('
|| v_insert
|| ') VALUES ('
|| How to fetch the column names here
|| ');';
EXECUTE IMMEDIATE v_ins_query;
END LOOP;
Please help me out with the above problem.

How to configure the iTunes,to display only folder name as Album.

How to configure the iTunes,to display only folder name as Album under Music.
I have a folder with name "English" under this I have plenty of folders which are either movie names or custom names created by me,inside of these are the music files. I just want all the files to be copied to the iPod with out any album artwork(which the itunes display under "Album By Artist" contains).The "Album By Artist" doesnt seem to contain just the folder name,it gets something else like the website from where the music file downloaded. This makes me irritating to browse through iPod or iTunes.
Please help me in configuring,so that I can just see the same folder/music hierarchy I see in my windows machine in the iPod.

Yep, I agree with Jurjen. It is not only limited to ACTVT, but rather fields of other objects as well which are "action" or "activity" related.
I would start the other way around - give them '03' only and investigate any transaction specific claims that it is not enough. There will be a few...
