How to Getting 10lack records from 2 tables and share into 10 tables

Hi Experts,
i have some special requirement about counting records before we we procees them in to intenal table.
here is the sample code .
**Needed to get users for ref users data
DATA: BEGIN OF gt_usr02 OCCURS 0,
        bname LIKE usr02-bname,
      END OF gt_usr02.
DATA:g_wa_usr02 LIKE LINE OF gt_usr02.
**Needed To get reference users data
DATA: BEGIN OF gt_usrefus OCCURS 0,
        bname LIKE usrefus-bname,
        refuser LIKE usrefus-refuser,
        END OF gt_usrefus.
DATA:g_wa_usrefus LIKE LINE OF gt_usrefus.
SELECTION-SCREEN :BEGIN OF BLOCK blk1 WITH FRAME TITLE text-000.
SELECT-OPTIONS : s_user FOR usr02-bname.
SELECTION-SCREEN :END OF BLOCK blk1.
START-OF-SELECTION.
REFRESH:gt_usr02,gt_usrefus.
CLEAR:gt_usr02,gt_usrefus
CLEAR:g_wa_usr02,g_wa_usrefus ,
SELECT bname FROM usr02 INTO TABLE
       gt_usr02 WHERE bname IN s_user. "say suppose "*" in s_user
1.Here i need to get no of records befor we are getting data from this select statement
basically i need to know the no of records (like count (sy-dbcnt) with same condition like below.
IF NOT gt_usr02 IS INITIAL.
    SELECT bname refuser FROM usrefus INTO TABLE gt_usrefus
     FOR ALL ENTRIES IN gt_usr02
    WHERE bname = gt_usr02-bname AND refuser <> space.
ENDIF.
2.if i found no of records based on that i have to broke those records into diff tables
say i found 10,000 records ,that time i have spilt those 10,000 records into 10 tables(Similar strcture like table gt_usrefus ) with 1000 records each .
Can you help us.this requirement is for avoiding memory issues.

Hi nagraju102,
- please try to post code formatted as code
- splitting a table of 10000 records into 10 tables of 1000 records will use not less memory at all, even a little bit more for the administrative overhead
- the numer of lines in an internal table can determinde used system function lines( itab )
- you can create an internal table of references and then create any number of internal tables,
data:
lt_tabref type table of ref to data.
field-symbols:
<table> type table,
<tabref> type ref to data.
DO 10 TIMES.
append initial line to lt_tabref assigning <tabref>.
create data <tabref> type table of usrefus.
assign <tabref>->* to <table>.
perform fill_table changing <table>."fill this table as you prefer
ENDDO.
Here you have 10 internal tables with USREFUS structure.

Clemens

Urgent- How to separate bad records from load and put into a separate table

We have an error handling requirement in ODI 11g from the client that whenever a bad record is encountered the execution flow shud not stop rather it shud separate those records into an error table so that at the end of the load we shud be left with all the records (except bad records) in the target table and those bad records shud be there in a separate error table.
The definition of the bad records may include the size of a column or datatype mismatch between source and target table. How to implement this error handling strategy in ODI or is there any out of box solution that we can leverage Please Help.
Thanks & Regards,
SBV
Edited by: user13133733 on Dec 23, 2011 4:45 AM

Hi SBV,
Please find my responses below,
I have tried the steps suggested, however i have some doubts:
1. What all data exceptions (e.g. primary key constraint violation etc.) are covered in this mechanism?Yes you can handle PK,FK, Check constraints violations etc., using CKM.
2. If there is a column size mismatch between source and target table will this work? (I think not because i tried it and it'll give error before populating the I$ table, because I$ is created according to the source).
You are right column size mismatches will not be captured as a part of default CKM property.
Also i am getting an error in the creation of SNP_CHECK_TAB step. In my case ODI is by default making a query like "create table .SNP_CHECK_TAB" , now this dot (.) before SNP_CHECK_TAB is making it an invalid table name and hence this step is a warning (not an error), but in the next step (delete previous checksum) it is throwing an error as this step is also looking for .SNP_CHECK_TAB table which is not there.
Please help me where the issue lies. I have NO idea why it is making that query by default I have freshly impoted the CKM Oracle and used it.
This is coz there is no DEFAULT physical schema not defined at your target data server.
Go to, Topology Manager-> Phy architecture -> <Your Technology>-> <Your target data server>-> expand, open up your physical schema and check DEAFULT.
Thanks,

please give me idea
thanking you
aamir
select m.accid,m.title,d.dr,d.cr
from master m, detail d
where m.accid=d.accid (+)The outer join operator (+) will get you all the details from master and any details from the detail if they exist, but the master details will still be got even if there are not details.
Note: Oracle 10g now supports ANSI standard outer joins as in:
select m.accid,m.title,d.dr,d.cr
from master m LEFT OUTER JOIN detail d on m.accid=d.accid

How can one read a Excel File and Upload into Table using Pl/SQL Code.

How can one read a Excel File and Upload into Table using Pl/SQL Code.
1. Excel File is on My PC.
2. And I want to write a Stored Procedure or Package to do that.
3. DataBase is on Other Server. Client-Server Environment.
4. I am Using Toad or PlSql developer tool.

If you would like to create a package/procedure in order to solve this problem consider using the UTL_FILE in built package, here are a few steps to get you going:
1. Get your DBA to create directory object in oracle using the following command:
create directory TEST_DIR as ‘directory_path’;
Note: This directory is on the server.
2. Grant read,write on directory directory_object_name to username;
You can find out the directory_object_name value from dba_directories view if you are using the system user account.
3. Logon as the user as mentioned above.
Sample code read plain text file code, you can modify this code to suit your need (i.e. read a csv file)
function getData(p_filename in varchar2,
p_filepath in varchar2
) RETURN VARCHAR2 is
input_file utl_file.file_type;
--declare a buffer to read text data
input_buffer varchar2(4000);
begin
--using the UTL_FILE in built package
input_file := utl_file.fopen(p_filepath, p_filename, 'R');
utl_file.get_line(input_file, input_buffer);
--debug
--dbms_output.put_line(input_buffer);
utl_file.fclose(input_file);
--return data
return input_buffer;
end;
Hope this helps.

Get the data from excel and insert into the database

I want to read the data from excel file, get the data from excel and insert into the database.

You can use the Apache POI HSSF API to read data from Excel files and you can use the Sun JDBC API to insert data in database.
This has nothing to do with JSP/JSTL.

How to get a parameter from BPC and use it in ABAP program

Hello gurus!
I got a problem...
SAP BPC will send parameters such as year, division, category, company code and so on via script logic to SAP BW.
I need to get these parameters from BPC and use them in a ABAP program as a filter.
This ABAP program will do several routines and return new values to BPC. It must be made on ABAP and I need to filter data to avoid performance issues.
Does anybody knows how to do it? or have a example of it?
Thank you in advance.
Regards,
Rubens Kumori

Hello, I'm looking for a suggest.
I need to pass two parameters (users can input them in a data manager package in bpc) to a BAdI.
In this BAdI I write a code that store those parameters in a InfoObject.
The problem is:
- one parameter is for CATEGORY value. CATEGORY is a dimension of the application and I read the value with a code like this:
      READ TABLE it_cv INTO l_s_it_cv
           WITH TABLE KEY dim_upper_case = 'C_CATEGORY'.
- other parameter is a generic DATE. this parameter is not a dimension of the application and I don't know how I can retrieve this value in BAdI.
      READ TABLE it_cv INTO l_s_it_cv
           WITH TABLE KEY dim_upper_case = '.....'.
The data manager dynamic script is:
PROMPT(SELECTINPUT,,,,"%CATEGORY_DIM%")
PROMPT(TEXT,%SELECTED_DAY%,"Write the date (format YYYYMMDD)",)
I also have a dynamic constant that assign the name %CATEGORY_DIM% to "C_CATEGORY" value.
Can anyone help me?
thanks a lot

How to get selected row from a non-bind ADF table

Hi,
I have an ADF table that is based on a collectionModel built programmatically. The collectionModel is this:
model = new SortableModel(new ArrayList<ArrayList>());
Hence, it is not a binding table. My question is how to get the selectedRows from a non-bind table.
I am used to building binding ADF table and I know we can get it from voiterator.getCurrentRow, since the selectionListener is set to the binding....collectionModel.makeCurrent
<af:table value="#{bindings.ItasLookupTypesVO1.collectionModel}"
selectedRowKeys="#{bindings.ItasLookupTypesVO1.collectionModel.selectedRow}"
selectionListener="#{bindings.ItasLookupTypesVO1.collectionModel.makeCurrent}"
</af:table>
I am thinking maybe I need to write my own selectionListener, but need more advice/ideas of what's the codes in the customer selection Listener to get it from my SortableModel.
Please help.
Thanks
-Mina

I'm not sure if this works in your case, but check out the selection listener I write in this blog http://wp.me/pcBZk-eu
You should use the selection event and check the added set. This should give you access to the selected row.

-Sandip

Rashmi/Kukku,
First of all, Thanks for your help!
Is there any other way in which we can access tables other than using BAPIs or RFCs?
In my case, there is a table structure which has to be updated with values after validating a key. i don't think there is any RFC available now. do i need to create bapi/rfc for that?

How to get multiple records from internal table through BDC

PERFORM DYNPRO USING:
'X' 'SAPMM61L' '0500',
' ' 'BDC_OKCODE' '=NEWC',
'X' 'SAPMM61L' '0500',
' ' 'BDC_CURSOR' 'PLPTU-PLWRK(01)',
' ' 'BDC_OKCODE' '=TAKE',
' ' 'PLPTU-PLWRK(01)' '2531'. (2531 is a plant)
This is the recording used to get plant via BDC of MS31.
Using this code i can get only single plant...
If i want to get multiple plants from an internal table,how i can change this code?
Since it is a recording i cant put this code in LOOP..ENDLOOP.
Suggest any method for doing this....
Awaiting for ur reply...

Hi,
While recording also record the scroll down button.
The you can place different plant in the BDC using loop and endloop

How to get missing records from one table

I have one table with many records in the table. Each time a record is entered the date the record was entered is also saved in the table.
I need a query that will find all the missing records in the table.
so if I have in my table:
ID          Date          Location
1           4/1/2015        bld1
2           4/2/2015        bld1
3           4/4/2015        bld1
I want to run a query like
Select Date, Location FROM [table] WHERE (Date Between '4/1/2015' and '4/4/2015') and (Location = bld1)
WHERE Date not in
(Select Date, Location FROM [table])
and the results would be:
4/3/2015   bld1
Thank you

Do you have a table with all possible dates in it? You can do a left join from that to your above mentioned table where the right side of the join is null. If you don't have a table with all possible dates you could user a numbers table.
Below is one way to achieve what you want with a numbers table...
DECLARE @Table table (ID Int, DateField Date, Location VarChar(4))
DECLARE @RunDate datetime
SET @RunDate=GETDATE()
IF OBJECT_ID('dbo.Numbers') IS NOT NULL
DROP TABLE NUMBERS
SELECT TOP 10000 IDENTITY(int,1,1) AS Number
into Numbers
FROM sys.objects s1
CROSS JOIN sys.objects s2
ALTER TABLE Numbers ADD CONSTRAINT PK_Numbers PRIMARY KEY CLUSTERED (Number)
INSERT INTO @Table (ID, DateField, Location)
VALUES ('1','20150401','bld1')
,('1','20150402','bld1')
,('1','20150404','bld1');
WITH AllDates
as
SELECT DATEADD(dd,N.Number,D.StartDate) as Dates
FROM Numbers N
cross apply (SELECT CAST('20150101' as Date) as StartDate) as D
select *
from AllDates AD
left join @Table T on AD.Dates = T.DateField
where ad.Dates between '20150401' and '20150404'
AND T.ID IS NULL

How to get Date value from database and display them in a drop down list?

Hello.
In my Customers table, I have a column with Date data type. I want to create a form in JSP, where visitors can filter Customers list by year and month.
All I know is this piece of SQL that is convert the date to the dd-mm-yyyy format:
SELECT TO_CHAR(reg_date,'dd-mm-yyyy') from CustomersAny ideas of how this filtering possible? In my effort not to sound like a newbie wanting to be spoonfed, you can provide me link to external notes and resources, I'll really appreciate it.
Thanks,

Hi
What part is your biggest problem?? I am not experienced in getting data out of a database, but the way to get a variable amount of data to show in a drop down menu, i have just messed around with for some time and heres how i solved it... In my app, what i needed was, a initial empty drop down list, and then using input from a text-field, users could add elements to a Vector that was passed to a JComboBox. Heres how.
package jcombobox;
import java.awt.*;
import java.awt.event.*;
import java.util.Vector;
import javax.swing.*;
public class Main extends JApplet implements ActionListener {
    private Vector<SomeClass> list = new Vector<SomeClass>();
    private JComboBox dropDownList = new JComboBox(list);
    private JButton addButton = new JButton("add");
    private JButton remove = new JButton("remove");
    private JTextField input = new JTextField(10);
    private JPanel buttons = new JPanel();
    public Main() {
        addButton.addActionListener(this);
        remove.addActionListener(this);
        input.addActionListener(this);
        buttons.setLayout(new FlowLayout());
        buttons.add(addButton);
        buttons.add(remove);
        add(dropDownList, "North");
        add(input, "Center");
        add(buttons, "South");
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == addButton) {
            list.addElement(new SomeClass(input.getText()));
            input.setText("");
        } else if (e.getSource() == remove) {
            int selected = dropDownList.getSelectedIndex();
            dropDownList.removeItemAt(selected);
    public void init(String[] args) {
        setSize(400,300);
        getContentPane().setLayout(new BorderLayout());
        getContentPane().add(new Main());
}And that "SomeClass" is show here
package jcombobox;
public class SomeClass {
    private String text;
    public SomeClass(String input) {
        text = input;
    public String toString() {
        return text;
}One of the things i struggled a lot with was to get the dropdown menu to show some usefull result. If the list just contains class references it will show the memory code that points to that class. Thats where the toString cones in handy. But it took me some time to figure that one out, a laugh here is welcome as it should have been obvious :-)
When the app is as simple as this one, using a <String> vector would have been easier, but this is just to demonstrate how to place classes in a vector and get some usefull info out of it, hope this answered some of your question :-)
The layout might have been easier to write, than using the toppanel created by the JApplet and then the two additional JPanels, but it was just a small app brewed together in 15 minutes. Please comments on my faults, so that i can learn of it.
If you need any of the code specified more, please let me know. Ill be glad to,

How to get a value from a column inside a table

Hi,
I have got the following problem. I have got a table with some data inside. And a new column, which is not in the dataprovider. Now i search for an opportunity to go through the rows of the table and check the value of this column. I cant do this with the dataprovider or the rowset. My question is now how can i do this? The table object doesnt seem to have a corresponding method.
Thanks in advance for help
Acinonyx

this is some code you can use (based on Winston's and others' tips):
put this in you page bean:
private HashSet selectedRows = new HashSet();
public boolean isSelected() {
TableRowDataProvider trdp = (TableRowDataProvider)getBean("currentRow");
if (trdp == null) {
return false;
RowKey rowKey = trdp.getTableRow();
if (this.selectedRows.contains(rowKey.getRowId()))
return true;
else
return false;
public void setSelected(boolean b) {
TableRowDataProvider trdp = (TableRowDataProvider)getBean("currentRow");
RowKey rowKey = trdp.getTableRow();
if (checkbox1.isChecked()) {
this.selectedRows.add(rowKey.getRowId());
Object v = this.t_fotoDataProvider.getValue("fieldName", rowKey);
} else {
this.selectedRows.remove(rowKey.getRowId());
and then bind the "selected" property of the checkbox column to the "selected" property of the page bean.
Now, eveytime the page is submitted, you can do something useful, for example, in the setSelected() method (the row that starts with Object v = ... get's the value of some field corresponding to the checked row)
