Convert this query to ABAP and display the results
Hi Everyone,
I have a sql query in native sql (oracle). I want execute it in ABAP editor and display the results.
I need to get this to an internal table and display the results. How do i write the script any help will be great use to me.
Here is the query:
<i> select (select decode(extent_management,'LOCAL','*',' ') ||
decode(segment_space_management,'AUTO','a ','m ')
from dba_tablespaces where tablespace_name = b.tablespace_name) || nvl(b.tablespace_name,
nvl(a.tablespace_name,'UNKOWN')) name,
kbytes_alloc kbytes,
kbytes_alloc-nvl(kbytes_free,0) used,
nvl(kbytes_free,0) free,
((kbytes_alloc-nvl(kbytes_free,0))/
kbytes_alloc)*100 pct_used,
nvl(largest,0) largest,
nvl(kbytes_max,kbytes_alloc) Max_Size,
decode( kbytes_max, 0, 0, (kbytes_alloc/kbytes_max)*100) pct_max_used from ( select sum(bytes)/1024 Kbytes_free,
max(bytes)/1024 largest,
tablespace_name
from sys.dba_free_space
group by tablespace_name ) a,
( select sum(bytes)/1024 Kbytes_alloc,
sum(maxbytes)/1024 Kbytes_max,
tablespace_name
from sys.dba_data_files
group by tablespace_name
union all
select sum(bytes)/1024 Kbytes_alloc,
sum(maxbytes)/1024 Kbytes_max,
tablespace_name
from sys.dba_temp_files
group by tablespace_name )b
where a.tablespace_name = b.tablespace_name order by 1;
</i>
Thanks,

Hi Prashant,
Native SQL commands in ABAP are placed between EXEC SQL and ENDEXEC. You can place all your statements in between these EXEC SQL and ENDEXEC in a report.
EXEC SQL [PERFORMING <form>].
<Native SQL statement>
ENDEXEC.
Check this link to know about Native SQL

How to Read the one Source Column data and Display the Results
Hi All,
I have one PR_ProjectType Column in my Mastertable,Based on that Column we need to reed the column data and Display the Results
Ex:
Pr_ProjectType
AD,AM
AD
AM
AD,AM,TS,CS.OT,TS
AD,AM
like that data will come now we need 1. Ad,AM then same we need 2. AD also same we need 3. AM also we need
4.AD,AM,TS,CS.OT,TS in this string we need AD,AM only.
this logic we need we have thousand of data in the table.Please help this is urgent issue
vasuHi Vasu,
Based on your description, you want to eliminate the substrings (eliminated by comma) that are not AD or AM in each value of the column. Personally, I don’t think this can be done by just using an expression in the Derived Column. To achieve your goal, here
are two approaches for your reference:
Method 1: On the query level. Replace the target substrings with different integer characters, and create a function to eliminate non-numeric characters, then replace the integer characters with the corresponding substrings. The statements
for the custom function is as follows:
CREATE FUNCTION dbo.udf_GetNumeric
(@strAlphaNumeric VARCHAR(256))
RETURNS VARCHAR(256)
AS
BEGIN
DECLARE @intAlpha INT
SET @intAlpha = PATINDEX('%[^0-9]%', @strAlphaNumeric)
BEGIN
WHILE @intAlpha > 0
BEGIN
SET @strAlphaNumeric = STUFF(@strAlphaNumeric, @intAlpha, 1, '' )
SET @intAlpha = PATINDEX('%[^0-9]%', @strAlphaNumeric )
END
END
RETURN ISNULL(@strAlphaNumeric,0)
END
GO
The SQL commands used in the OLE DB Source is like:
SELECT
ID, REPLACE(REPLACE(REPLACE(REPLACE(dbo.udf_GetNumeric(REPLACE(REPLACE(REPLACE(REPLACE([ProjectType],'AD,',1),'AM,',2),'AD',3),'AM',4)),4,'AM'),3,'AD'),2,'AM,'),1,'AD,')
FROM MyTable
Method 2: Using a Script Component. Add a Derived Column Transform to replace the target substrings as method 1, use Regex in script to remove all non-numeric characters from the string, add another Derived Column to replace the integer
characters to the corresponding substring. The script is as follows:
using System.Text.RegularExpressions;
Row.OutProjectType= Regex.Replace(Row.ProjectType, "[^.0-9]", "");

Hi,
That depends on whether spriden_pidm is unique, and on what you want for results.
Whenever you have a problem, post a little sample data (CREATE TABLE and INSERT statements, relevamnt columns only) for all tables, and the results you want from that data.
If you can illustrate your problem using commonly available tables (such as those in the scott or hr schemas) then you don't have to post any sample data; just post the results you want.
Either way, explain how you get those results from that data.
Always say which version of Oracle you're using.
It looks like you're doing something similiar to the following.
Using the emp and dept tables in the scott schema, produce one row of output per department showing the highest salary in each job, for a given set of jobs:
DEPTNO DNAME LOC JOB_1 SAL_1 JOB_2 SAL_2 JOB_3 SAL_3
20 RESEARCH DALLAS ANALYST 3000 MANAGER 2975 CLERK 1100
10 ACCOUNTING NEW YORK MANAGER 2450 CLERK 1300
30 SALES CHICAGO MANAGER 2850 CLERK 950On each row, the jobs are listed in order by the highest salary.
This seems to be analagous to what you're doing. The roles played by sortest_pidm, sortest_tesc_code and sortest_test_score in your sortest table are played by deptno, job and sal in the emp table. The roles played by spriden_pidm, id and name in your spriden table are played by deptno, dname and loc in the dept table.
It sounds like you already have something like the query below, that produces the correct output, except that it does not include the dname and loc columns from the dept table.
SELECT deptno
, MAX (DECODE (rn, 1, job)) AS job_1
, MAX (DECODE (rn, 1, max_sal)) AS sal_1
, MAX (DECODE (rn, 2, job)) AS job_2
, MAX (DECODE (rn, 2, max_sal)) AS sal_2
, MAX (DECODE (rn, 3, job)) AS job_3
, MAX (DECODE (rn, 3, max_sal)) AS sal_3
FROM (
SELECT deptno
, job
, max_sal
, ROW_NUMBER () OVER ( PARTITION BY deptno
ORDER BY max_sal DESC
) AS rn
FROM (
SELECT e.deptno
, e.job
, MAX (e.sal) AS max_sal
FROM scott.emp e
, scott.dept d
WHERE e.deptno = d.deptno
AND e.job IN ('ANALYST', 'CLERK', 'MANAGER')
GROUP BY e.deptno
, e.job
GROUP BY deptno
;Since dept.deptno is unique, there will only be one dname and one loc for each deptno, so we can change the query by replacing "deptno" with "deptno, dname, loc" throughout the query (except in the join condition, of course):
SELECT deptno, dname, loc -- Changed
, MAX (DECODE (rn, 1, job)) AS job_1
, MAX (DECODE (rn, 1, max_sal)) AS sal_1
, MAX (DECODE (rn, 2, job)) AS job_2
, MAX (DECODE (rn, 2, max_sal)) AS sal_2
, MAX (DECODE (rn, 3, job)) AS job_3
, MAX (DECODE (rn, 3, max_sal)) AS sal_3
FROM (
SELECT deptno, dname, loc -- Changed
, job
, max_sal
, ROW_NUMBER () OVER ( PARTITION BY deptno -- , dname, loc -- Changed
ORDER BY max_sal DESC
) AS rn
FROM (
SELECT e.deptno, d.dname, d.loc -- Changed
, e.job
, MAX (e.sal) AS max_sal
FROM scott.emp e
, scott.dept d
WHERE e.deptno = d.deptno
AND e.job IN ('ANALYST', 'CLERK', 'MANAGER')
GROUP BY e.deptno, d.dname, d.loc -- Changed
, e.job
GROUP BY deptno, dname, loc -- Changed
;Actually, you can keep using just deptno in the analytic PARTITION BY clause. It might be a little more efficient to just use deptno, like I did above, but it won't change the results if you use all 3, if there is only 1 danme and 1 loc per deptno.
By the way, you don't need so many sub-queries. You're using the inner sub-query to compute the MAX, and the outer sub-query to compute rn. Analytic functions are computed after aggregate fucntions, so you can do both in the same sub-query like this:
SELECT deptno, dname, loc
, MAX (DECODE (rn, 1, job)) AS job_1
, MAX (DECODE (rn, 1, max_sal)) AS sal_1
, MAX (DECODE (rn, 2, job)) AS job_2
, MAX (DECODE (rn, 2, max_sal)) AS sal_2
, MAX (DECODE (rn, 3, job)) AS job_3
, MAX (DECODE (rn, 3, max_sal)) AS sal_3
FROM (
SELECT e.deptno, d.dname, d.loc
, e.job
, MAX (e.sal) AS max_sal
, ROW_NUMBER () OVER ( PARTITION BY e.deptno
ORDER BY MAX (sal) DESC
) AS rn
FROM scott.emp e
, scott.dept d
WHERE e.deptno = d.deptno
AND e.job IN ('ANALYST', 'CLERK', 'MANAGER')
GROUP BY e.deptno, d.dname, d.loc
, e.job
GROUP BY deptno, dname, loc
;This will work in Oracle 8.1 and up. In Oracle 11, however, it's better to use the SELECT ... PIVOT feature. -
Remote Call to Blazeds and displaying the result set in grid
Hi,
I want to call a remote method using Flex application from Blazeds and display the values in DataGrid. Can anyone help in this ?

1) add a results method to the remote object:
src.result="onResult(event.result)";
2) add the callback method: private function onResult(event : * = null)
:void{
if(event is
ArrayCollection)
myData =
ArrayCollection(event);
3) add the variable: private var myData:ArrayCollection;
4) make the dataProvider for the grid use the my data :
dataProvider=""
You can probably avoid all this by adjusting your dataProvider. I am just
not sure what it would be without experimenting. But definitely not what
you have. Maybe just {svc.result}. -

I would like to read a file and display the results in a table containing both strings and numbers?
Hi,
I just need a simple way of doing this as at the moment, i read one line at the time containing strings and numbers, whenever i convert this line to an array i loose the strings, if i want to display it, it displays as a group of lines while i would like to display it as a table with column headers. The file is an .xls worksheet.
Any suggestions?
Thanks
MeHi,
Look at attach vi.
If this is not what you need please clarify.
With ActiveX you can Open Excel, interact with it (read and write values to cells...
But if you can read it this way, I think it's easier.
Hope this helps,

Call a JSP from applet and display the results in the browser
Hello All,
I have written an applet which performs some functionality at the clinets browser. When the applets method finishes exectution, I would like to call
a jsp. The results of the JSP should be displayed like a normal page in the browser.
I tried creating a HttpURLConnection and calling the jsp but two things happened
1. The jsp call failed because the applet doesn't have a valid session id.
2. even if I disable the valid user check at the jsp, the results of the jsp are returned as a set of bytes to the applet. They are not displayed in the browser window.
Then I tried applet.getAppletContext().showDocument()... However with this api I cannot do a POST operation on the JSP with some input data because this takes only a URL as an input parameter.
Please help me in this problem and I will be very gratefull to you.
1. applet uses the same session id as the browser so that when applet makes a request to the jsp it does not get user invalid exception.
2. the results of the jsp are displayed on the browser and not given to the applet.
Thank you so much for your help.
regards,
Abhishek.I hope this can help you

Hi All,
I have a purpose in winforms to have a "notepad like" editor that saves what ever i type to a file on the hard drive and reads from based.
So what i have is a tab with a richtextbox docked to fill. I would like to have that richtextbox read from a file on the hard drive, then save the changes i type when i either click off the tab or live if possible.
I wills state that i am fairly new to the c# game and if this is possible and someone could post an example that would be awesome and totally appreciated.
Thanks,
jACFor those that are looking for the solution I went with here are the details
Reading the file:
// Wish List Section
wishListRichTextBox.ResetText();
string wlFolder = Application.StartupPath + "\\wishLists\\";
string wlPath = wlFolder + selectedProduct + ".rtf";
// Read from the text file and out put the results
try
{ // create directory if it does not exist
if (!Directory.Exists(wlFolder))
Directory.CreateDirectory(wlFolder);
} // create file if it does not exist
if (!File.Exists(wlPath))
File.Create(wlPath).Dispose();
var iStream = new FileStream(wlPath, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
var sr = new System.IO.StreamReader(iStream);
var readData = sr.ReadToEnd();
wishListRichTextBox.Text = readData;
sr.Close();
// If the read fails then output the error message in the same section
catch (Exception ex)
wishListRichTextBox.Text = "Error: " + ex.Message;
Writing the file:
private void wishlistTabChanged(object sender, EventArgs e)
if(menuTabControl.SelectedTab != wishListTab){
if (productComboBox.SelectedIndex >= 0)
try
string wlFolder = Application.StartupPath + "\\wishLists\\";
string wlPath = wlFolder + productComboBox.SelectedItem + ".rtf";
var oStream = new FileStream(wlPath, FileMode.Open, FileAccess.Write, FileShare.Read);
oStream.SetLength(0);
var sw = new System.IO.StreamWriter(oStream);
sw.WriteLine(wishListRichTextBox.Text);
sw.Close();
catch (Exception ex)
MessageBox.Show("Wish list for " + productComboBox.Text + " save failed. \n\nError: " +
ex, "Wish List Save Failed", MessageBoxButtons.OK, MessageBoxIcon.Error);

How to search XML data from a HTTPMultiService and display the result on the Spark List

How to join two lists and display the results in datasheet view.?
hello,
i have two lists that i would like to join, i know a method that has been described in the link below
http://www.codeproject.com/Articles/194252/How-to-Link-Two-Lists-and-Create-a-Combined-Ciew-i
however, here the data view is only limited to 30 rows and my resultant list is huge. I would like to know if there is a possibility to view the resultant list in a data sheet view ?I don't believe you can use the OOTB Datasheet view when joining lists. However, you should be able to increase your limit from 30 items to as many as you need (that doesn't trip the threshold set in Central Admin).

I have requirement as:
I have to map sf1 to target1 ( I do not have any problema in it)
target2 field must populate basing upon query which results. this should run with the input parameter sf1. If the query results then update target2 else update with MESSAGE_DONE.Hi Swarna,
What kind of query do you mean? In certain cases, it might be worthwhile to consider ABAP mapping, which seems to be the easiest way to do some sequential steps, especially for such a simple message structures.
Hope this helps,

}Console input is line buffered. This means you only get the first character a line after the newline has been inputed.
The same thing happen if you just type on the console.
I am not aware of any simple way around this.
IDEs get around this by changing the application run so that the input/output is captured as it happens and sent over a socket connection. -
Some methods are displaying the result on the server instead on the client.
When I test (form SeatReservationClient class) the method sri.showReservations() located in SeatReservationClient class the results are being displayed on the server side instead on the client but the method sri.numReservations() is displaying the result as i want it i.e. on the client. Please can anyone help me (as always on this forum) find a solution to this problem and display the results correctly?
I have 5 classes:
Interface
public interface SeatReservationInterface extends java.rmi.Remote
public boolean isReserved(int row, int seat) throws java.rmi.RemoteException;
public boolean reserve(int row, int seat) throws java.rmi.RemoteException;
public boolean cancel(int row, int seat) throws java.rmi.RemoteException;
public int numReservations() throws java.rmi.RemoteException;
public void showReservations() throws java.rmi.RemoteException;
Implementation
public class SeatReservationImpl extends java.rmi.server.UnicastRemoteObject implements SeatReservationInterface
private Seat[][] theatre;
* Implementations must have an explicit constructor in order to declare the RemoteException
* exception.
* Theatre constructor makes a new movie theatre with numRows rows and numSeats
* seats (chairs) in each row. All seats are unreserved (unoccupied) in the beginning.
public SeatReservationImpl(int numRows, int numSeats) throws java.rmi.RemoteException
theatre = new Seat[numRows][numSeats];
for(int row = 0; row <theatre.length; row++)
for(int col = 0; col<theatre[row].length; col++)
theatre[row][col] = new Seat();
* The method returns true if the seat at location (row, seat) is reserved.
* The method returns false in all other cases.
* Be careful that row numbers run from 1 to numRows, and seat numbers from
* 1 to numSeats.
public boolean isReserved(int row, int seat) throws java.rmi.RemoteException
return theatre[row-1][seat-1].isOccupied();
* Books the seat at location (row, seat) and returns true if that seat is available.
* Returns false if that seat is already reserved.
public boolean reserve(int row, int seat) throws java.rmi.RemoteException
return theatre[row-1][seat-1].occupy();
* Cancels a seat reservation at location (row, seat) is that seat was booked, and returns
* true in that case. The method returns false if that seat had not been reserved.
public boolean cancel(int row, int seat) throws java.rmi.RemoteException
return theatre[row-1][seat-1].release();
* Returns the number of reserved seats.
public int numReservations() throws java.rmi.RemoteException
int count = 0;
for(int i = 0; i < theatre.length; i++)
for(int j = 0; j < theatre[j].length; j++)
if(theatre[i][j].isOccupied())
count++;
return count;
* Prints an overview over all reservations. Reserved seats are shown as "*", available seats
* as "-". For each row the row number is shown, then a couple of blanks, and then the
* reservations. An example is
* 8 -----****----
* 7 ---**---**---
* 6 ----***------
* 5 -------------
* 4 -------------
* 3 ----------***
* 2 **-------
* 1 -------------
public void showReservations() throws java.rmi.RemoteException
for(int row = theatre.length-1; row>=0; row--)
System.out.print((row+1) + "\t");
for(int j = 0; j<theatre[row].length; j++)
if(theatre[row][j].isFree())
System.out.print("-");
else
System.out.print("*");
System.out.println();
return;
[i]Server import java.rmi.Naming;
public class SeatReservationServer
public SeatReservationServer()
try
SeatReservationInterface sri = new SeatReservationImpl(10, 5);
Naming.rebind("rmi://localhost:1099/SeatReservationService", sri);
catch (Exception e)
System.out.println("Trouble: " + e);
public static void main(String args[])
new SeatReservationServer();
Client
import java.rmi.Naming;
import java.rmi.RemoteException;
import java.net.MalformedURLException;
import java.rmi.NotBoundException;
public class SeatReservationClient
public static void main(String[] args)
try
SeatReservationInterface sri = (SeatReservationInterface) Naming.lookup("rmi://localhost/SeatReservationService");
/* Make two reservations */
System.out.println("Reservations:");
System.out.println("1,2");
System.out.println("1.3");
System.out.println("1,4");
sri.reserve(1,2);
sri.reserve(1,3);
sri.reserve(1,4);
System.out.println("The Seat is occupied - " + sri.isReserved(1,2));
System.out.println("The Seat is occupied - " + sri.isReserved(1,3));
System.out.println("The Seat is occupied - " + sri.isReserved(1,4));
/* Show the theatre */
sri.showReservations();
/* Release a seat that had been booked */
System.out.println("Release seat row 1 seat 2");
sri.cancel(1,2);
System.out.println("The Seat is occupied - " + sri.isReserved(1,2));
/* Show the number of total reservations and the theatre */
System.out.println("Number of reservations: " + sri.numReservations());
sri.showReservations();
catch (MalformedURLException murle)
System.out.println();
System.out.println("MalformedURLException");
System.out.println(murle);
catch (RemoteException re)
System.out.println();
System.out.println("RemoteException");
System.out.println(re);
catch (NotBoundException nbe)
System.out.println();
System.out.println("NotBoundException");
System.out.println(nbe);
catch (java.lang.ArithmeticException ae)
System.out.println();
System.out.println("java.lang.ArithmeticException");
System.out.println(ae);
Class containing instance methods
public class Seat
private boolean occupied;
* Constructors:
Seat()
Seat(boolean o)
occupied = o;
* Instance methods:
public boolean isFree()
return !this.occupied;
public boolean isOccupied()
return this.occupied;
public boolean occupy()
if(occupied)
return false;
else
occupied = true;
return true;
public boolean release()
if(!isOccupied())
return false;
else
occupied = false;
return true;
}Your code is working as expected. The server executes System.out.println in showReservations() and this comes out on the server console. The client executes System.out.println() after calling numReservations and this comes out at the client. Any other expectations are misplaced.

Hi I want to create a search form with drop down search criteria. This form should then search on the same site and display the search results. Is there HTML available for this? Or an oline site that I can use to build this form? I created a form in Jotform.com, but this form doesn't search the site, instead it sends me an e-mail. Do you have a solution for me? Thanks.
