How to Map N number of columns from input to output schemas at a time?

Hi,
I am new to BODI. In my project we are using DAT files, which contains more than 100 columns, as Source. At the Data Flow Level, in Query Transformation we are manually mapping columns from INPUT Schema to OUTPUT Schema one by one.
Is there any way to MAP all the columns at a time from INPUT schema to OUTPUT schema.
Hope I am clear with my question.
Thanks for your support.
Sudhakar

Hi,
Thanks for your answer.It's really helpul.
But in my case, Source Filed names and Target Field names are different. As we know, OUTPUT column names should be same as Target Field names.
I am just wondering is there any option to MAP columns between INPUT schema and OUTPUT Schema at a time, like Informatica.
In Informatica you can MAP all the columns at a time between any 2 Transformation by using their port order, even though the Filed names are different .
Do we have any option like this in BODI?
Regards,
Sudhakar

How to fetch less number of columns from a ref cursor

I have a ref cursor which has 10 columns. After "OPEN"ing the ref cursor I want to "FETCH" only 3 columns. When I try that I am getting error. How to achieve that?
Regards.
Shantanu.

Supposing your first 3 columns are "stable" in name and type for any SQL statement you use, you can do something like:
SQL> create or replace procedure stable (sql_s in varchar2)
2 is
3   empno emp.empno%type;
4   ename emp.ename%type;
5   a sys_refcursor;
6 begin
7   open a for 'select empno, ename from (' || sql_s ||')';
8   fetch a into empno, ename;
9   while(a%found) loop
10    dbms_output.put_line(ename || '/' || empno);
11    fetch a into empno, ename;
12   end loop;
13   close a;
14 end;
15 /
&nbsp
Procedure created.
&nbsp
SQL> set serveroutput on;

How can I remove the Location column from the search results in a .chm file?

How can I remove the Location column from the search results in a .chm file?
I generated the file in Robohelp HTML 9.
As far as I know it's used when you've combined more than one source into the final help file. It is possible (though I don't remember doing it) that I did that once a couple of years ago but now I'm only using one source - the project that's generating the .chm.
Can anyone tell me how I can remove it?
Thanks
Tom

In Project Setup look at the Window properties. I think you will find Advanced Search is ticked.

Are the numbers in ASCII? Use the Spreadsheet String to Array function. Wire in a space constant to the delimiter and a 1D array of doubles to the array type. You can then use Index Array to get the value you want.

How can I edit the SamAccountName column from the list or be able to edit it?

Hello,
In my view for a SharePoint list, I see three columns for SamAccountName. This list is for listing staff as a directory, so there are phone numbers, names, emails addresses, division, department and such. The SamAccountName
column for some people has incorrect username or is blank. When I edit a record in the list, the SamAccountName column is not available to edit.
How can I edit the SamAccountName column from the list or be able to edit it?
I do have user profiles working and importing profiles from AD, but the list still shows empty or incorrect SamAccountName for some records.

How do I unlock an iPod touch from putting the password in too many times?

Restore...
From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod.

If your intention is just changing the content you are passing to bpel/returning from bpel
Here is another way
just update your default created xsd files with new elements, update wsdl elements in message definition and chnage bpel code to reflect new elements in activities

How to get the sine wave sample of the input and output in the same time?

I discovered that the samples were acquired did not in the same time in my vi.Could you tell me how to get the sine wave sample of the input and output in the same time?

Hello Yun_Zhu,
Your VI looks like you started from an example, and you are on the right track.
To clarify are you trying to synchronize the input and the output waveforms? If you you will need to share a time base and a start trigger. Check out the synchronization examples from LabVIEW

How to get the number of columns in a result set???

hi everyone..
i am trying to establish a servlet applet communication....
my applet send the sql query to the servlet as serialised string and then the servlet executes the query...
Since i need to pass the result back to the applet, i thaught of passing the whole reult set to the applet..but that seems to be not possible..
so i thaught of storing my result set data in a vector and then pass the vector,but the first problem that i came across is that how to get the number of colums in a result set....
so is there a way to get the number of columns in a result set...???
and also i would like to know if it possible to send my whole result set to the applet bye serialization or by any method...???
thanx in advance

You shouldn't do. It expenses resources (you should always close the ResultSet and the Statement as fast as possible). Simply gently process it into a Collection or Map of DTO's. Those are serializable.

How to access variable number of columns using ref cursor !

Hi,
I am trying to get variable number of columns using ref cursor.
Declare
mySzSql varchar2(2000);
Type dynSqlRC is Ref cursor;
current_cur dynSqlRC;
tbl_rec alt_42_consolidated%Rowtype;
Begin:
/* This works */
mySzSql := 'select *
from
Table1
Where
rowid = ''AAEWNEABXAAAAkxAAA''';
/* i want something like this to work, this is not working, giving missing variable name error */
mySzSql := 'select col1, col2, col3
from
Table1
Where
rowid = ''AAEWNEABXAAAAkxAAA''';
open current_cur for mySzSql;
fetch current_cur into tbl_rec;
close current_cur;
End;
I do have the list of desired columns which I am looking to fetch, so after taking that in the record type, how should i get their values. Is it possible to traverse tbl_rec declared above and if column name matches then I will store the value in the array and finally return this array.
Can somebody please tell me how to do this.
Thanks

It appears that this is a followup to How to loop through columns selected by select clause which is itself a followup to [url="
How to execute dynamic sql"]this earlier thread.
Assuming these are intended to be followup questions, can we please stick to a single thread? That makes it a lot easier to understand the situation and follow the conversation. Starting multiple threads makes it harder to follow the conversation.

How to send a number by SMS from contact list on 2...

Guys, I cracked my brains to solve how to send a number from contact list by SMS in 2630.
Maybe there's no such option at all?
Please help!!!
Message Edited by berzerk on 16-Dec-2008 09:24 PM

I don't think there is such an option on a limited phone like the 2630.
On phones running S60 such as the Nseries and Eseries devices (and a few others) there is an option to copy a number from the contacts into the clipboard and you can subsequently paste it into a new message. Older S40 phones like the 2630 don't have a clipboard facility to do copy/paste actions.
