Fibonacci series using recusrion in a Procedure

Hi,
Could anyone please help me to query a fibonacci series using recusrion in a Procedure.

Create or replace Function fnu_fibonnaci(p_iNumber integer)
return integer
is
nuFib integer;
nuP integer;
nuQ integer;
Begin
if p_iNumber is not null then
     if p_iNumber=0 then
        nuFib:=0;
     Elsif p_iNumber=1 then
            nuFib:=1;
     Else
        nuP:=0;
        nuQ:=1;
        For nuI in 2..p_iNumber loop
            nuFib:=nuP+nuQ;
            nuP:=nuQ;
            nuQ:=nuFib;
        End loop;
     End if;
End if;
return(nuFib);

Nth digit term of the fibonacci series

hi everyone i want to find the nth digit term of the fibonacci series like 144 is the 12th term and is the 1st term to contain 3 digits
so i made the following code
import java.math.*;
class FibNew
BigInteger d=new BigInteger("1");
BigInteger a=new BigInteger("5");
BigInteger b=new BigInteger("8");
BigInteger e=new BigInteger("1");
BigInteger c=new BigInteger("1");
int count=1,i;
          FibNew()
          while(count!=3)//To calculate the first number with 3 digits
                    c=a.add(b);
                    a=b.multiply(d);     //assiging a=b
                    b=c.multiply(d);     //assiging b=c
                    e=c.divide(BigInteger.valueOf(10));
                    System.out.println(e);
                       if(e.equals("0")==false)
                           for(i=1;i<=10;i++)
                              e=e.divide(BigInteger.valueOf(10));

           }//ending of constructor
          public static void main(String args[])
          FibNew f=new FibNew();
}i cant find whats wrong with this it should print the value of e,but it doesnt
i used BigINtegers as i want to also find the first nth term with 1000 digits,the series starts from 5,8,13,21.........

Use this instead. It reroutes the error stream to a text file because
it will always be too long to read in any command window.
I also added a timer.

DYNAMIC CREATION OF LINE SERIES USING ACTIONSCRIPT

There's something wierd about flex or im doing something
wrong?
- when i create a line series manually using mxml and specify
a id for the series, it works.
- similarly when i try to dynamically create a line series
using actionscript & define an "id" property, flex does not
understand! what am i doing wrong?
code for reference:
private function addSeries(series:Array,
yField:String,id:String) // addseries(series,"date","1000")
var ls:LineSeries= new LineSeries();
var stroke:Stroke = new Stroke()
ls.yField = yField;
ls.xField="ts"
ls.dataProvider=dp
ls.id=id // tried defining it dynamically, but flex does not
find
this.mychart.series.push(ls)
THIS IS THE ERROR I GET : "TypeError: Error #1010: A term is
undefined and has no properties."

I see... I played around with the line chart ...
Hopefully this helps... if not forgive me...
I know why you are trying to use the id property which i
agree doesn't work.
since the series is an array in your lineChart use the index
to set the visible property false/true.
lineChart.series[0].visible = true/false;
<mx:Lineseries id="a1" visible="true"
dataProvider="{whatever}" />
<mx:Lineseries id="a2" visible="false"
dataProvider="{whatever}"/>
create a function called init();
public function init():void
var lineS1:LineSeries = new LineSeries();
lineS1.visible = true/false;
lineChart.series.push(lineS1);
var lineS2:LineSeries = new LineSeries();
lineS2.visible = true/false;
lineChart.series.push(lineS2);
... and the key is to call this init function on initialize
event...NOT on createComplete event
<mx:LineChart.... initialize="init()" .... />
and to show both lines... call this function...
public function showLines():void
lineChart.series[0].visible = true;
lineChart.series[1].visible = true;
Hope this helps....

Tax calculation in CRM using R/3 pricing procedure

Hello Experts
We are using R/3 pricing procedure to calculate list prices in CRM.
The condition record for Taxes are maintained for condition type UTXJ in SD which is calling for tax procedure TAXUSJ and condition type JR1.
The records are maintained in FTXP. This is the SAP Standard way of maintaining taxes if external tax software is not used.
We have downloaded the condition records and condition types in CRM. The tables have all the required records downloaded from R/3.
When creating an order in Webshop the tax is not getting calculated.
The pricing analysis shows that the condition record for UTXJ condtion type is met, but it is not showing the tax maintained for condition type JR1.
Have we missed any settings here?
If we are using R/3 billling does the TTE needs to be activated for calculating taxes in the webshop?
If TTE needed to be used for calculating taxes, what are the settings needed to be configured?
Thanks in advance for the valuable advice.
Sastri

Hi Sastri,
I am facing this problem with TAX Condition Records: Pricing error: Mandatory condition MWST is missing. I am using a R/3 pricing procedure correctly downloaded to CRM.
You say that you have downloaded the condition records and condition types in CRM. SAP Library says 'Prerrequisites: You have downloaded the tax condition records from SAP ECC'.
I don't know If my problem is caused because I haven't downloaded any Tax Condition Records. The fact is that I cannot determine which one is the Condition Object to download in R3AS.
I would really appreciate if you or anyone could tell me which object you did use.
thanks in advance,
Pablo

Using spool in a procedure

Hi,
I've a package with 6 procedures.
In one procedure I need to load the data into a flat file. The procedure contains only one select statement.
example:
procedure pro_test as
select * from emp;
end pro_test;
Shell script is being used to call one procedure inside the package and that procedure is calling remaining procedures inside it.
connected to database using sqlplus.
Can anyone help me out how I can spool the select statement inside the procedure. Version of oracle is 11g.

Hi,
Why do you want to do
SELECT *
FROM    table_name;
inside the procedure? Why not have your script run the procedure (without the query above), and then do that query afterwards, when you can use SPOOL to put the results in a file?
If you really must write a file from a procedure, here's an example of how to use utl_file.
First, SYSTEM (or some other user with the CREATE ANY DIRECCTORY system privilege) must create a directory, and grant privileges to use it. For example:
CREATE OR RPLEACE DIRECTORY a_dir AS 'C:\Foo\A_Folder';
GRANT ALL ON DIRECTORY a_dir TO PUBLIC;
Typically, SYSTEM does this once, and other people use it hundreds of times.
You might create a file in that directory like this:
CREATE OR REPLACE PROCEDURE write_dept
IS
    f utl_file.file_type;
BEGIN
    f := utl_file.fopen ('A_DIR', 'Dept.txt', 'W');
    FOR r IN ( SELECT *
                   FROM    scott.dept
    LOOP
        utl_file.put_line ( f
                          , TO_CHAR (r.deptno, 'FM00')
                            || ' '
                            || RPAD (r.dname, 15)
                            || r.loc
    END LOOP;
    utl_file.fclose (f);
END write_dept;

Using dynamic value in procedure on column

I want a PL/sql procedure to select the data from the column dynamically into a variable .
My friend suggested its not possible in PL/sql ,its only possible in sql .
What i want is when i execute the PL/sql procedure the a_1 must get the value of the data in the table,i do not want to use execute immediate in pl/sql.
I create a table A
create table A (a1 number,a2 number,a3 number);
insert into a values (1,2,3);
then i create a procedure
create or replace
procedure test_a (var IN number)
as
a_1 number;
i number;
z varchar2(5);
begin
if var=1
then
i:=1;
elsif var = 2
then
i:=2;
z:='A2';
end if;
SELECT 'a'||i into a_1 from a;
end;

I prefer reference cursors over execute immediate if I must do dynamic SQL (and have learned not to do it unless necessary - among other things dynamic SQL is hard to debug and maintain).
The advantages to ref cursors are
* execute immedate will only retrieve one row, ref cursors as many as you want
* easier for me to build the query first, then execute it (though you can do this with execute immediate too) for debugging
You can buiid the query dynamcially but have to be careful to make sure the select list matches the INTO clause on the fetch statements. Although the queries in the example below are hard coded I could have done something like
v_command_c := 'select '||var1||', '||var2||' from '''||table_name||'''';
open refcur for v_command_c;To randomize your column selection use something like the above with IF logic and a randomizer, possibly the DBMS_RANDOM package or a time extraction.
Something like
SET SCAN OFF
SET SERVEROUTPUT ON
DECLARE
--define composite data types
--reference cursor type - structure
TYPE RefCursorType   IS REF CURSOR;
--collection (index-by table) type - structure
TYPE TablesTableType IS TABLE OF user_tables.table_name%TYPE
    INDEX BY BINARY_INTEGER;
--define ref cursors to be used in BEGIN section
UserTablesCursor RefCursorType;
UserViewCursor   RefCursorType;
--define actual index-by tables to be used in BEGIN section
NamesTable TablesTableType;
ViewsTable TablesTableType;
--define internal procedures to be used in this script
PROCEDURE ListItems(RefCursor IN RefCursorType,
    DataTable IN OUT TablesTableType
    ) IS
    Counter   INTEGER := 1;
    TableName user_tables.table_name%TYPE;
BEGIN
    FETCH RefCursor INTO DataTable(Counter);
    Counter := Counter + 1;
    WHILE RefCursor%FOUND LOOP
      FETCH RefCursor INTO DataTable(Counter);
      Counter := Counter + 1;
    END LOOP;
END; --ListItems;
PROCEDURE WriteItems(DataTable IN TablesTableType) IS
BEGIN
    FOR i IN 1..DataTable.count LOOP
      dbms_output.put_line(DataTable(i));
    END LOOP;
END; --WriteItems;
BEGIN
OPEN UserTablesCursor FOR
    SELECT table_name
      FROM user_tables;
ListItems(UserTablesCursor,NamesTable);
CLOSE UserTablesCursor;
dbms_output.put_line('user_tables');
dbms_output.put_line('--------------');
WriteItems(NamesTable);
--second defintion & set of calls
dbms_output.put_Line(CHR(13));
OPEN UserTablesCursor FOR

Subreport using the same Stored Procedure

I have a main report and a subreport that uses the same stored procedure. The stored procedure has 12 parameters and what I want to avoid is the user having to enter the same parameter values twice. When I created the subreport I put in the parameters + one field, the employee id field so that I could just test it on one employee.
After I entered the subreport into the main report, when I got to refresh the data, it's asking for params for BOTH reports. Is there any way to get around this? Because of the way the stored procedure returns the data, I had to create a subreport instead of just fitting it into one of the footers. I've looked at the subreport link and added the employee id as the key. When I ran it the first time, it returned the wrong date range on the sub.
Help! this thing is Way passed due!!

Right click on the sub report and choose change sub report links
Top left pane contains your main report parameters use > to add
In the bottom left corner of that dialog then scroll down until you see the corresponding sub report parameter
Repeat for each parameter
This should then take the main report params and pass into the sub report

Use of variable in Procedure

I created a global variable that contains a result of a query.
I used it in a procedure using SQL but when I run the prcedure I have the following error :
com.sunopsis.sql.SnpsMissingParametersException: Missing parameter
Could you tell me how to use my variable ?
My SQL Code is the following and I bolded the variable
SELECT A.SESS_NAME ,
A.SCEN_VERSION,
A.SESS_BEG ,
A.SESS_DUR,
C.NNO,
RTRIM(LTRIM(B.STEP_NAME)) TABLE_NAME
,SUM(C.STEP_DUR)
, SUM(NB_INS) NB_INS
FROM COUNT_TMP D , SNP_SESSION A , SNP_SESS_STEP B, snp_step_log C
WHERE
'PS_' || RTRIM(LTRIM(B.STEP_NAME)) = D.TABLE_NAME AND
A.SESS_BEG >= TO_DATE( #DATE_BASCULE , 'DD/MM/YYYY') AND
A.SESS_NO = B.SESS_NO AND
B.SESS_NO = C.SESS_NO AND B.NNO = C.NNO
GROUP BY A.SESS_NAME , A.SCEN_VERSION ,A.SESS_BEG ,A.SESS_DUR, C.NNO ,B.STEP_NAME
ORDER BY A.SESS_NAME , A.SCEN_VERSION, C.NNO
Thank you
Meapri

Thanks a lot it did not fail.
Now I am going to check if my procedure does something.
Steps to use a variable resulting from a query in a procedure. ( In my case I used a alphanumeric variable )
1) I declare a global Variable My_Variable. I chose
- type 'Alphanumeric'
- default value SELECT TO_CHAR(DATE_LAST_PROCESS) FROM PS_S1_ODI_BASCULE
- action 'Dernière valeur'
- I refresh my variable by running the query on the RDBMS
2)In the procedure I refer to my variable by writing '#My_Variable'. My SQL Code becomes
SELECT A.SESS_NAME ,
A.SCEN_VERSION,
A.SESS_BEG ,
A.SESS_DUR,
C.NNO,
RTRIM(LTRIM(B.STEP_NAME)) TABLE_NAME
,SUM(C.STEP_DUR)
, SUM(NB_INS) NB_INS
FROM COUNT_TMP D , SNP_SESSION A , SNP_SESS_STEP B, snp_step_log C
WHERE
'PS_' || RTRIM(LTRIM(B.STEP_NAME)) = D.TABLE_NAME AND
A.SESS_BEG >= TO_DATE( '#DATE_BASCULE' , 'DD/MM/YYYY') AND
A.SESS_NO = B.SESS_NO AND
B.SESS_NO = C.SESS_NO AND B.NNO = C.NNO
GROUP BY A.SESS_NAME , A.SCEN_VERSION ,A.SESS_BEG ,A.SESS_DUR, C.NNO ,B.STEP_NAME
ORDER BY A.SESS_NAME , A.SCEN_VERSION, C.NNO

Use of function and procedures

when we need to use function rather than procedure or viceversa???

Welcome to the forum!
Use a function if you want to use the value it returns as you would use any other expression in a SQL statement:
SELECT SYSDATE
,       my_function (column1) AS c1
,       UPPER (column2)        AS c2
FROM    table_x;or in PL/SQL:
IF my_function (x) > 0 THEN ...Use a procedure otherwise; for example, if there is no value to be passed back.
Functions can have OUT (and IN OUT) arguments, but they can cause confusion. Many people use procedures whenever they need OUT arguemnts, which includes all situations where 2 or more values are passed back.
Any good book or site on PL/SQL, or any kind of procedural programming, should explain the differences between functions and procedures.
If you don't have at least that much guidance, it's better not to try using PL/SQL.

Find all tables used in a stored procedure

Hi,
I have a requirement where i have to find all the tables used in a stored procedures from different databases.
Ex: i have a stored procedure where i use few tables from MASTER database and some from STAGE database.When i have written a query to find all tables used in the stored procedure, i am getting only those database table where i run the query and procedure
exists.
I have stored procedure SP1 in Master database, but i use the tables from both master and stage.
When i run this, i am getting the tables only from Master database but not from stage. i hope my requirement is clear.
I am trying to find all the tables from all databases used by a stored proc.
;WITH stored_procedures AS (
SELECT
o.name AS proc_name, oo.name AS table_name,
ROW_NUMBER() OVER(partition by o.name,oo.name ORDER BY o.name,oo.name) AS row
FROM sysdepends d
INNER JOIN sysobjects o ON o.id=d.id
INNER JOIN sysobjects oo ON oo.id=d.depid
WHERE o.xtype = 'P')
SELECT proc_name, table_name FROM stored_procedures
WHERE row = 1
ORDER BY proc_name
Please advice

Your question is not entirely clear. You need to run the query on different databases.

Database updation using XML and stored Procedure?

Hello,
I want to perform updation in multiple tables using XML files.Please suggest can I do updation using xml and stored procedure.
If yes then which is more efficient and takes less time.
1.Updation using xml files only
2.Updation using xml files with stored procedure.
3.Stored procedure alone.
If direct xml and stored procedure communication is possible.then please write how.
Thanks in advance for any help.

Here's a sample. The next code drop of the XSQL Servlet will make the easy-to-do from within XSQL Pages:
package package1;

Hi, i have downloaded peppa pig series using itunes, and have tried to sync them to my Ipad Mini and IPhone 5, however it is not working it states "videos from your Itunes libary can not be copied to 'ipad' because they can not be played on this Ipad.

I have downloaded Peppa Pig series using Itunes and have tried to sync the tv programme to both my Ipad Mini and IPhone 5. However neither work saying that 'videos from Itunes Libary can not be copied to 'ipad' because they can not be played on this I Pad. I have downloaded the HD episodes is this my problem or do i need to download a 'video watching' app? Please help we are going away next week and the episodes were to help keep my toodler occupied on the plane. thank you

The error you received kinda looks like the one in this article: http://support.apple.com/kb/ts4223
But the iPhone 5 and the iPad mini should support HD videos.
