Do you have StockDs configured in your server config.xml?
I think the query should look more like this:
SELECT stocks.SYMBOL, stocks.EXCHANGE
FROM STOCK as stocks, ExchangeStream [Now] as datastream WHERE stocks.SYMBOL = datastream.SYMBOL

How to fetch the data from Ecc to BI ?

Hi everybody.
Can anyone briefly explain with the screen shots > How to fetch the datasource from RSA5 tcode in ECC to BI? How you replicate there? how the INFO PACKAGE , TRANSFORMATIONS, DTP , DSO, INFO CUBE was created? where we see the catalogs for this data.......THANKS IN ADVANCE

Hi.
You can follow the below steps to fetch the data from ECC to BI System.
1>Connection should be there between ECC and BW System.
2>Go to Tcode-RSA5 in ECC system and find your data source and then activate it.
3> Go to Tcode-RSA6 in ECC system to check whether your DS is available..if it is there then its been activated.
4>Go to Extract Checker tcode RSA3 and test the data and make sure data is correct.
5>login to BW Side..go to tcode RSA1-->Choose your source system. ECC -> double click on it and you will move to Data source>Select your Application component ex, SD,FI ...>Right click and replicate the Datasouce> Now on refresh you can see the datasource in BI System.
6>Install the related the Infoprovider .. cube or dso ..Connect the datasouurce and create Transformation.
7> Now create infopackage and run it in ful & init mode then do the delta for the new records.
Please refer the below link for more details on extraction.

Hi Rammohan,
You cannot use OPEN DATASET to transfer data from application server to presentation server.
You can do the following :
Do 1st point in BACKGROUND
1. Read the data file from application server into an internal table using OPEN DATASET
Do 2nd point in Foreground
2. Once you get the data into an internal table, then use FM GUI_DOWNLOAD to download it on presentation server
You cannot use the above 2 point together in Background because its not possible. Hence you need program it partially in background and partially in foreground.

Prashant

How to Fetch the Data from a Cube

Dear All,
We created a cube containing dimensions
Customer, Product, Branch, Activity, Time dimensions
using Oracle Analytical WorkSpace Manager.
Once Cube is created,
How can I see the Data existing in the Cube using normal SQL Queries ??? Through Analytical Workspace Manager Toll we r able to see the data. But our requirement is to see the data from the Cube using SQL Queries.
Regards,
S.Vamsi Krishna

Hey I got the Solution. It follows in this way :
A Cube is nothing but a Data Storage. Based on the Mapping we given it considers the data.
To fetch the data from the Cube -> we have to write the SQl Query as below :
     SELECT dealer_name,model_name,sales
     FROM TABLE(OLAP_TABLE('MDB.FINAL_AW DURATION SESSION',
     'DIMENSION dealer_name AS varchar2(30) FROM FINALDEAL
     DIMENSION model_name AS varchar2(30) FROM FINALMODEL'));
We can create View for the above statement o
we can apply group by ,rollup, etc etc clauses
and even we can write where clauses for the above select statement.
But now my doubt is :
can we apply any calculations while mapping the Level to an Dimension.
Generally we will map Level toa dimension as DBUSER.TABLENAME.COLUMN NAME
can we apply any calculation like :
MIS.PROPKEY020MB.MATURITY_DATE+2
Please help for the above.
If any wrong is there please let me know
Regards,
S.Vamsi Krishna
can we apply

FYI.. Checked the characteristcis is exactely matching with aggregates..
and also it is giving the message as:
Characteristic 0G_CWWPTY is compressed but is not in the aggregate/query
Can some body explain me about this error message.. pls let me know solution asap..
Thankyou in advance.

Hi
Deactivate the aggregates and then rebuild the indexes and then activate the aggregates again.

Error in fetching the data from textfield and inserting to the database..

I'm using Java Swing as front end and MySQL as backend using the netbeans ide..I am trying to fetch the data from the textfiled in the form and insert to the database table.i've skipped the generated code..In the following code i get the erro cannot find symbol "stmt" in the actionPerformed method..
mport java.awt.event.*;
import java.sql.*;
public class BarcodeReader extends JFrame implements ActionListener {
public BarcodeReader() {
initComponents();
nb.addActionListener(this);
public void jdbcConnect(){
Connection con=null;
String url = "jdbc:mysql://localhost:3306/";
String db = "mynewdatabase";
String driver = "com.mysql.jdbc.Driver";
String user = "usrname";
String pass = "pwd";
try{
String s=newtxt.getText();
con=DriverManager.getConnection(url + db, user, pass);
Statement stmt=con.createStatement();
Class.forName(driver);
public void actionPerformed(ActionEvent e){
try{
jdbcConnect();
stmt.executeUpdate("INSERT into machine(mname) values '"+jTextField1.getText()+"'");
}}catch (Exception ex) {
System.out.println(ex);
public static void main(String args[]) {
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
new BarcodeReader().setVisible(true);
}

There are far too many errors to try and clear.
For one, the exception references the actionPerformed method (according to your text), so why is that not shown here?
For another you are performing, possible time-consuming, actions, and even worse IO actions, on the event thread, which is a huge no-no.
You are not closeing your resources properly, if at all, which is another huge no-no.
You are completely mixing your "view" (the gui), and your "model" (the data related classes), which is another huge no-no.
etc, etc, etc.

Extractor class to fetch the data from PA0105

Hi All,
Can anyone suggest me the extractor class used to fetch the data from the table PA0105.
Any information regarding this will be highly helpful.

If you give PA0105 all data will be extracted.
Or if you need any specific data you need to know the filed names first. check the table from SE16 for identifying the field names. and do it accordingly.
Please reward points

How to fetch the data from pl/sql table dynamically

Hi All, I have the requirement of comparing two db views data in pl/sql. So, I have bulk collect the view into pl/sql table. But, the issue is, It is expecting to provide the column name for comparison. But, in my case, column name is dynamic. So, i cannot provide the column name directly for comparison.
For eg: In my view t1_VW, i have 4 columns. stid, c1,c2,c3,c4 and similar structure for t2_vw
my code
TYPE v1_type IS TABLE OF t1_vw%ROWTYPE;
l_data v1_type;
TYPE v1_type1 IS TABLE OF t2_vw%ROWTYPE;
l_data1 v1_type1;
test varchar2(1000);
test1 varchar2(1000);

SELECT * Bulk collect into l_data

SELECT * Bulk collect into l_data1

select l_data(1).stid into temp1 from dual; -- It is working fine and gives me the value properly
-- But, in my case, we are reading the column names from array, i am constructing the query dynamically and execute it.
test :='select l_data(1).stid into temp1 from dual';
execute immediate test into temp1;
-- I am getting error as follows:
Error report:

- Please help me to get rid of this issue. Is it possible to construct the query dynamically and fetch the data?. If not, is there any other better approach to compare the data between two views?.

Output should display what are all columns changed and its old value and new value.
For eg., output should be
COLUMNNAME OLD_VALUE NEW_VALUE STID
C1 20 10 1
C2 50 40 2
C3 60 70 2
C2 80 90 3Why no do this only via a simple sql ?
create table a (STID number, C1 number, C2 number, C3 number);
insert into a values (1, 20, 30, 40)
insert into a values (2, 40, 50, 60);
insert into a values (3, 90, 80, 100);
create table b as select *
from a where 1 = 0;
insert into b values (1, 10, 30, 40)
insert into b values (2, 40, 40, 70);
insert into b values (3, 90, 90, 100);
commit;And now you can issue such a kind of select
SELECT stid , c1, c2, c3
 FROM
( SELECT a.*,
 1 src1,
 to_number(null) src2
 FROM a
 UNION ALL
 SELECT b.*,
 to_number(null) src1,
 2 src2
 FROM b
 GROUP BY stid , c1, c2, c3
 HAVING count(src1) <> count(src2)
 order by stid;I would then create a new table a_b_difference having the same structure as a or b and insert into it like this
create table a_b_diff as select * from a where 1 = 0;
insert into a_b_diff
SELECT stid , c1, c2, c3
 FROM
( SELECT a.*,
 1 src1,
 to_number(null) src2
 FROM a
 UNION ALL
 SELECT b.*,
 to_number(null) src1,
 2 src2
 FROM b
 GROUP BY stid , c1, c2, c3
 HAVING count(src1) <> count(src2)
 order by stid
 ;Then each time there is a difference between a column in a and its equivalente one in b (per unique stid ) a record will be inserted in this table.
You can do more by adding the name of the table in front of each record in this table to see exactly where the data comes from
