It appears that you want to call a stored procedure which in JDBC are implemented by CallableStatements
See http://java.sun.com/docs/books/tutorial/jdbc/basics/storedprocedures.html

Select last value for each day from table

Hi!
I have a table that stores several measures for each day. I need two queries against this table and I am not quite sure how to write them.
The table stores these lines (sample data)
*DateCol1                 Value       Database*
27.09.2009 12:00:00       100           DB1
27.09.2009 20:00:00       150           DB1
27.09.2009 12:00:00       1000          DB2
27.09.2009 20:00:00       1100          DB2
28.09.2009 12:00:00       200           DB1
28.09.2009 20:00:00       220           DB1
28.09.2009 12:00:00       1500          DB2
28.09.2009 20:00:00       2000          DB2Explanation of data in the sample table:
We measure the size of the data files belonging to each database one or more times each day. The value column shows the size of the database files for each database at a given time (European format for date in DateCol1).
What I need:
Query 1:
The query should return the latest measurement for each day and database. Like this:
*DateCol1       Value      Database*
27.09.2009        150          DB1
27.09.2009       1100          DB2
28.09.2009        220          DB1
28.09.2009       2000          DB2Query 2:
The query should return the average measurement for each day and database. Like this:
*DateCol1       Value      Database*
27.09.2009       125          DB1
27.09.2009      1050          DB2
28.09.2009       210          DB1
28.09.2009      1750          DB2Could someone please help me to write these two queries?
Please let me know if you need further information.

For first query you can use analytic function and solve it.
with t
as
select to_date('27.09.2009 12:00:00', 'dd.mm.yyyy hh24:mi:ss') dt,       100 val,           'DB1' db from dual union all
select to_date('27.09.2009 20:00:00', 'dd.mm.yyyy hh24:mi:ss'),       150,           'DB1' from dual union all
select to_date('27.09.2009 12:00:00', 'dd.mm.yyyy hh24:mi:ss'),       1000,          'DB2' from dual union all

select dt, val, db
from (
select row_number() over(partition by trunc(dt), db order by dt) rno,
       count(*) over(partition by trunc(dt), db) cnt,

How to return the result set of multiple select statements as one result set?

Hi All,
I have multiple select statements in my stored procedure that I want to return as one result set
for instance
select id from tableA
union
select name from table b
but union will not work because the result sets datatypes are not identical so how to go about this ?
Thanks

You have to CAST or CONVERT (or implicitly convert) the columns to the same datatype. You must find a datatype that both columns can be converted to without error. In your example I'm guessing id is an int and name is a varchar or nvarchar.
Since you didn't convert the datatypes, SQL will use its data precedence rules and attempt to convert name to an int. If any row contains a row that has a value in name that cannot be converted to an int, you will get an error. The solution is
to force SQL to convert the int to varchar. So you want something like
select cast(id as varchar(12)) from tableA
union
select name from tableb
If the datatypes are something other that int or varchar, you must find a compatable datatype and then convert one (or both) of the columns to that datatype.

How to set the parameter selection *optional* for each subreport?

Hi,
I am using Crystal Reprots 11.
I create 10 subreports, and each subreport contains a Parameters Field.
The 10 subreports are put in 10 footer sections in increasing order, i.e. subreport1, subreport2, subreport3, ..., subreport10.
When I use "Print Preview" to take a look at the whole report, CR prompts a "Edit Values" window for selecting parameter values for all 10 subreports.
For example, if I only select parameter values for subreport1 and click "OK", 9 error messages on the "Edit Values" window come out above the selection list box of every other subreports (i.e. subreport2 ~ subreport10) showing that: 'The value is not valid'.
Sometimes, I just want to review some specific subreports but not all.
How should I do to set the parameter selection optional (not mandatory) for each subreport?
Thank you in adavance.
Edited by: Holdup on Feb 17, 2012 3:44 PM

Hi,
Here's how you can make the prompts optional (Assuming you're using CR 2008 or higher):
1) Go into each subreport
2) You should see the parameter in the Field Explorer. Right-click the name and select Edit > Look for an option called 'Optional Prompt'. Set it to true
3) If you have a record selection in the subreport, then you need to modify the selection formula to something like this:
if not(hasvalue({?Parameter_Name})) then True else = {?Parameter_Name}
Hope this helps!

How to add a dummy row in the result set of a SELECT statement.

Hello Everyone -
I have requirment to add a dummy row in the result set of a SELECT statement.
For e.g. lets say there is a table Payment having following colums:
Payment_id number
status varchar2(10)
amount number
payment_date date
so here is the data :-
Payment_id Status Amount payment_date
1 Applied 100 12/07/2008
2 Reversed 200 01/ 06/2009
3 Applied 300 01/ 07/2009
Here is my SQL
Select * form payment where payment_date >= 01/01/2009
Output will be
2 Reversed 200 01/ 06/2009
3 Applied 300 01/ 07/2009
My desired output is below
2 Reversed 200 01/ 06/2009
3 Applied 300 01/ 07/2009
2 Reversed -200 01/ 06/2009 ------(Dummy Row)
Thrid row here is the dummy row which I want to add when status is "Reversed"
I would be very thankful for any kind of help in this regard ...
Thanks,
Gaurav

Cartesion joining against a dummy table is a useful method of creating a dummy row:
with my_tab as (select 1 cust_id, 1 Payment_id, 'Applied' Status, 100 Amount, to_date('12/07/2008', 'mm/dd/yyyy') payment_date from dual union all
                select 1 cust_id, 2 Payment_id, 'Reversed' Status, 200 Amount, to_date('01/06/2009', 'mm/dd/yyyy') payment_date from dual union all
                select 1 cust_id, 3 Payment_id, 'Applied' Status, 300 Amount, to_date('01/06/2009', 'mm/dd/yyyy') payment_date from dual union all
                select 2 cust_id, 1 Payment_id, 'Applied' Status, 100 Amount, to_date('12/07/2008', 'mm/dd/yyyy') payment_date from dual union all
                select 2 cust_id, 2 Payment_id, 'Reversed' Status, 200 Amount, to_date('01/05/2009', 'mm/dd/yyyy') payment_date from dual union all
                select 2 cust_id, 3 Payment_id, 'Applied' Status, 300 Amount, to_date('01/06/2009', 'mm/dd/yyyy') payment_date from dual union all
                select 2 cust_id, 4 Payment_id, 'Reversed' Status, -400 Amount, to_date('01/06/2009', 'mm/dd/yyyy') payment_date from dual union all

NB. You may have to mess around with the ordering if that's not come back in the order you wanted. You didn't mention what the rules were for any expected ordering though, so I've made up my own *{;-)
Also, I added an identifier (cust_id) to differentiate between different sets of payments, since that's usually the case. Remove that if it's not applicable for your case.

When using IN you must use a range table afterwards.
Try this :
DATA: BEGIN OF ibsis OCCURS 100,
         ebeln LIKE bseg-ebeln,
         ebelp LIKE bseg-ebelp,
         bsis LIKE bsis,
         ldgrp TYPE fagl_ldgrp.
DATA: END OF ibsis.

FIELD-SYMBOLS : <fs_ZFINITEMCAT> TYPE any.
DATA: l_item_catecory TYPE pstyv.
SELECT VALFROM AS LOW
          INTO CORRESPONDING FIELDS OF TABLE GT_ZFINITEMCAT
          FROM SETLEAF
          WHERE SETNAME EQ 'ZFIN_ITEMCAT'.
LOOP AT GT_ZFINITEMCAT ASSIGNING <fs_ZFINITEMCAT>.
     <fs_ZFINITEMCAT>-SIGN       = 'I'.
     <fs_ZFINITEMCAT>-OPTION = 'EQ'.
ENDLOOP.
LOOP AT ct_ibsis[] ASSIGNING <ibsis>.
"Check if we can find one item of the wrong category, if so then we remove the documents.
     SELECT SINGLE pstyv INTO l_item_catecory
       FROM vbap
       WHERE vbeln = <ibsis>-bsis-zuonr
         AND pstyv NOT IN GT_ZFINITEMCAT. "getting error here (The line structure of the table "GT_ZFINITEMCAT" is incorrect.)

How to use SET ID in select statement of SQ02

Hi,
I have a infoset, where for one of my Zfield, i have writen a select statement in order to get my ouput.
if aufk-aufnr = 'XYZ'.
select sum( FKBTR ) from fmifiit into zfmifiit
where fikrs = aufk-kokrs
and fipex IN capex
and wrttp NE '51'.
endif.
For the above statement, i have created (with 10 single values, table name FMCI, field name FIPEX) a SET id named CAPEX and used with IN operator.
But when i generating the infoset i am getting error like below
The IN operator with "CAPEX" is followed neither by an internal table nor by a value list
I was using IN opeartor for set ids during validation / substitutions, where if i have to validate multiple single values.
What to do here?

You need to specify "Default Values" in the report parameter property. Choose similar option used in the "Available Values" option, this will allow the parameter to check "Select All".

Is There any difference in Set @Var=ColmnName and Select @Var =Column from Table. I am using it in SSIs for Dynamic Packages

hey there, Kindly elaborate me the difference Between Set and Select clause while Providing value to a Variable or Even a Column.
    Declare @var nvarchar(Max)
    Set @var= (Select TestName+ cAst(TestId as nvarchar) from TblTest where TestID=1)
    Insert into TblTest(TestName)
    Values (@var)
    Declare @var nvarchar(Max)
    Select @var= (Select TestNAme + Cast(TestId as Nvarchar(MAx)) from TblTest Where TestID=1)
    Insert into TblTest(TestName)
    Values(@var)
Values and result I am getting is Same in Both.
But just wondering if there is any Difference. and if Any which Should I prefer.
And Which one uses less Resources.

I like this article

How to set the default selected option as NO_OPTION in a JoptionPane

This is just an example program to create the same scenario in the project.When clicked on OK button, it will pop up a JOptionPane confirm dialog with YES-NO buttons.I want to set the default selected button as NO button. In the below program, the keyboard focus is set on NO button, but in the look and feel the selection is still YES button. Can anyone suggest a solution to make both the focus on NO button?
public class Test extends JPanel implements ActionListener{
     Test() {
          JButton btn = new JButton("OK");
          this.add(btn);
          btn.addActionListener(this);
     public void actionPerformed(ActionEvent e) {
          Object[] o = {"Yes", "No"};
          JOptionPane p = new JOptionPane("Are u sure?",JOptionPane.QUESTION_MESSAGE,JOptionPane.YES_OPTION,null,o,null);
          //p.setWantsInput(false);
          p.setInitialSelectionValue(o[1]);
          try {
               UIManager.setLookAndFeel(new MetalLookAndFeel());
          } catch (UnsupportedLookAndFeelException e1) {
               // TODO Auto-generated catch block
               e1.printStackTrace();
          //p.setFocusCycleRoot(false);
          p.setInitialValue(o[1]);

          if(p.getValue() == o[0]) {
               System.out.println("yes");
          }else if(p.getValue() == o[1]) {
               System.out.println("no");
          //p.setWantsInput(true);

not sure what you're trying to do, but try this
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

Test()
    JButton btn = new JButton("OK");
    this.add(btn);
    btn.addActionListener(this);
public void actionPerformed(ActionEvent e)
    Object[] o = {"Yes", "No"};
    int value = JOptionPane.showOptionDialog(null,"Are u sure?","",-1,-1,null,o,o[1]);
    if(value == 0) System.out.println("yes");
    else if(value == 1) System.out.println("no");
public static void main(String[] args)
    UIManager.put("Button.defaultButtonFollowsFocus", Boolean.TRUE);
    Test t = new Test();
    JFrame f = new JFrame();
    f.getContentPane().add(t);
    f.pack();
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    f.setSize(500, 500);

rsau/user_selection                                 1
rsau/max_diskspace/per_day                  1950M
rsau/max_diskspace/per_file                 650M
rsau/enable                                               1
   I activated security audit profile in sm19 also.But when iam going to sm20 for analysis of security audit log iam not getting report iam getting this message :     The result set for this selection was empty.
Gudie me for the same.
Thanku

Hi,
The result set for this selection was empty.
I think your configuration is OK except one thing...
Check in SM19, if you have selected "Filter Active" check box in "Filter 1 and Filter 2" screen and Also "Audit Classess".
Even though security audit is enabled in SM19, without selecting filter it will not log the events and give you the above message.

RE: Setting initial DropList selection

Gary writes...

Does anyone know how to set the initially displayed selection
of a DropList to something other than the first element of the
array. <DropList>.IndexValue is supposed to be settable
according to the documentation, but it doesn't seem to be so.Gary, try setting the <DropList>.IndexValue in your Display method AFTER
the "self.Open()" call. I reported this bug sometime ago, and I believe
it will be fixed in an up coming build of R3.

Hi Gary !
If setting <DropList>.IndexValue doesn't work, I suppose you set it
before invoking the Self.Open() method of your UserWindow.
Try to set the IndexValue attribute of your DropList after invoking the
Self.Open() method. I think it will work.
Hope this helps !
