CREATE OR REPLACE FUNCTION demo
(i_in IN number)
RETURN NUMBER
IS
BEGIN
RETURN i_in*2;
END demo;
Hope that helps ... also, remember you can't use precision and scale (in the case of NUMBER), or length (in the case of VARCHAR2) for the parameters but you can ANCHOR (%TYPE or %ROWTYPE)
Good luck!

It is possible to get giving parameter field name in function module

i have one question like below .
at main report .
call funciton Fm1
exporting
     var1 = W_A
     var2 = W_B
at function module i want to get giving parameter field name, in here value was "W_A" and "W_B" .
plz give me some hints or any advise .

Only a hint:
If you have a fm with an unspecified parameter like
FUNCTION ZTESTBABLFM.
*"*"Lokale Schnittstelle:
*" IMPORTING
*"     REFERENCE(INPUT)
type-pools: sydes.
data: fieldinfo type SYDES_DESC.
describe field input into fieldinfo.
ENDFUNCTION.
you can get some information from DESCRIBE FIELD either using INTO as above or with other options as LENGTH, TYPE ...

Passing field name into Cursor

I would like to pass the name of a field for the WHERE clause, into a cursor. In my application I need to change the field name for the where clause. I get an "Invalid Number" error when I try the following:
cursor l_sel2Cur (c_group varchar2)
is
select email from test_grp_tbl6 where c_group = 1;
select column_name
into l_colName
from listserv_grp_lk
where lg_id = v_listserv_grp;
open l_sel2Cur(l_colName);
I hope this is enough explanation. I have seen examples where the value for the where clause is passed in, but not where the field name itself is passed in. Is this possible?
Thanks in advance,
John

See the following example:
SQL> create or replace procedure print_enames(in_col in varchar, in_val in varchar2) is
2 c sys_refcursor;
3 v_name emp.ename%type;
4 begin
5    open c for 'select ename from emp where '||in_col||'='''||in_val||'''';
6    loop
7     fetch c into v_name;
8     exit when c%notfound;
9     dbms_output.put_line('ename='||v_name);

How to pass column name at run time in function.

how to pass column name at run time in function as parameter.
thank in advance
pramod patel

Hello,
Using dynamic sql you can pass column name to function. well I am not getting what you really want to do ? Please write in more detail. By the way I am providing one example here. see it uses dynamic sql.
Create or replace function fun_updtest (p_columnname_varchar2 in varchar2,
p_value_number in number)
return number is
v_stmt varchar2(500);
begin
v_stmt := 'update emp
set '||p_columnname_varchar2||' = '||to_char(p_value_number)||'
where empno = 7369';
execute immediate v_stmt;
return 0;
commit;
end;
call to this function can be like this..
declare
v_number number;
begin
v_number := fun_updtest('SAL',5000);
end;

How to find the names of Function Module used in the program

Hi all,
can you people help me with this issue.I want to the names of all the Function Module used in the program along with their parameters into an internal table.It will be helpful for your suggestions.
Kind Regards,
Edited by: Prasenjit Sengupta on Nov 20, 2008 7:39 AM

Take structure of internal table as

Pass table name as a parameter to function

Is there a way to pass table name as a parameter to functions? Then update the table in the function.
Thanks a lot.

Hi, Harm,
Thank you very much for your suggestion and example. But to get my program work, i need to realise code like follows:
CREATE OR REPLACE FUNCTION delstu_func(stuno char) RETURN NUMBER AS
BEGIN
EXECUTE IMMEDIATE 'DELETE FROM student s' ||
'WHERE' || 's.student_number' || '=' || stuno;
LOOP
DBMS_OUTPUT.PUT_LINE('record deleted');
END LOOP;
END;
SELECT delstu_func('s11') FROM STUDENT;
The intention is to check if such a function can perform operations such as update, delete and insert on occurence of certain values. When executing the above statement, the system returns an error message:
ERROR at line 1:
ORA-00933: SQL command not properly ended
ORA-06512: at "SCMJD1.DELSTU_FUNC", line 3
Could you tell me where is wrong?

The 'argumentname' argument passed to the 'Methodename 'function is not of type 'Dto name'

Hi, there!
Sr for that question, because it should be pretty easy to answer, but i'm totally new to coldfusion
and googled for about an hour now. I have a orm DTO.cfc:
<cfcomponent entityname="testDTO" persistent="true" table="test" schema="informix" output="false">
    
</cfcomponent>
and have a service Methode in test.cfc
    
    <cffunction name="createTest" returntype="testDTO" access="remote">
        <cfargument name="item" type="testDTO" required="true" />
        
        <cfset entitysave(item) />
        
        <cfreturn item/>
    </cffunction>
i try to call via the the <cfInvoke>-Tag
<cfset lieferant = entityNew('test')>
<cfinvoke
    component="#request.componentbase#.test"
    method="createTest"
    item="#test#"
    returnvariable="test">
but the error
'The ITEM argument passed to the createLieferant function is not of type testDTO.'
appears on function call. I just can't find a way to tell cf that lieferant is of type testDTO.
When i type the methodes parameter to struct the methode call works well.
Thanks for your help in advance!
Florian

I'm assuming your extract there isn't quite right:
<cfset lieferant = entityNew('test')>
<cfinvoke
    component="#request.componentbase#.test"
    method="createTest"
    item="#test#"
    returnvariable="test">
You're doing item="#test#", surely this should be item="#lieferant#"?
In which case, you've done <cfset lieferant = entityNew('test')>, which is of type "test", not "testDTO"?
If you're still having trouble, remove the item="" attribute from CFINVOKE and use CFINVOKEARGUMENTs instead.

Passing TABLE NAME as parameter is possible or not?

I want develop a small/simple report like this
TABLE NAME :
WHERE :
ORDER BY :
QUERY ROWS
In the above model i want to pass all the three (TABLE NAME,WHERE and ORDER BY) as a parameter.
My doubt, is that possible to pass TABLE NAME as a parameter? If so!
When i enter any TABLE NAME it has to fetch me out the records of that table (Based on WHERE condition and ORDER BY).
Is that possible to do?
Need some help!
Edited by: Muthukumar Seshadri on Aug 10, 2012 6:19 PM

Yes, it is possible with lexical parameters. Look in the help for examples:
SELECT Clause
SELECT &P_ENAME NAME, &P_EMPNO ENO, &P_JOB ROLE FROM EMP
P_ENAME, P_EMPNO, and P_JOB can be used to change the columns selected at runtime. For example, you could enter DEPTNO as the value for P_EMPNO on the Runtime Parameter Form.
Note that in this case, you should use aliases for your columns. Otherwise, if you change the columns selected at runtime, the column names in the SELECT list will not match the Report Builder columns and the report will not run.
FROM Clause
SELECT ORDID, TOTAL FROM &ATABLE
ATABLE can be used to change the table from which columns are selected at runtime. For example, you could enter ORD for ATABLE at runtime.
If you dynamically change the table name in this way, you may also want to use lexical references for the SELECT clause (look at the previous example) in case the column names differ between tables.
WHERE Clause
SELECT ORDID, TOTAL FROM ORD WHERE &CUST
ORDER BY Clause
SELECT ORDID, SHIPDATE, ORDERDATE, TOTAL FROM ORD ORDER BY &SORT You have to be really careful with this approach. Dynamic SQL may cause serious performance problems.

Pass column-name as a parameter to reports

Hello,
the code below calls a report. But now I want to sort the rows in the report. For example I have a text-item in my form-modul. If I type a column-name and press the button then the rows should be sorted in the report. Is it possible tp pass column-names as parameter to reports?
DECLARE
repid REPORT_OBJECT;
v_rep VARCHAR2(100);
rep_status VARCHAR2(20);
BEGIN
repid := find_report_object('STATIONSTOPOLOGIE');
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_EXECUTION_MODE,RUNTIME);
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_COMM_MODE,SYNCHRONOUS);
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_DESTYPE,CACHE);
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_DESFORMAT,'html');
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_SERVER,'rep_oracle-dev');
-- SET_REPORT_OBJECT_PROPERTY(repid,REPORT_OTHER,'paramform=no pdeptno='||:dept.deptno);
v_rep := RUN_REPORT_OBJECT(repid);
rep_status := REPORT_OBJECT_STATUS(v_rep);
WHILE rep_status in ('RUNNING','OPENING_REPORT','ENQUEUED')
LOOP
rep_status := report_object_status(v_rep);
END LOOP;
IF rep_status = 'FINISHED' THEN
WEB.SHOW_DOCUMENT('http://oracle-dev:8888/reports/rwservlet/getjobid'||
substr(v_rep,instr(v_rep,'_',-1)+1)||'?'||'server=rep_oracle-dev','_blank');
ELSE
message('Error when running report');
END IF;
END;

Hi,
the work has been done in reports. You can use a lexical parameter in reports to add a condition for sorting to the query like:
select .. from .. where ... &p_order.
Then add another parameter to the report (for example p_param). Fill p_param via your interface in forms (SET_REPORT_OBJECT_PROPERTY(repid,REPORT_OTHER, ....) with the column name. Then build a report trigger like:
if :p_param is null
then
:p_order:= null;
else
:p_order:= 'order by '||:p_param;
end if;
But have a look, that p_param can only get correct values.

Pass table name as parameter in prepared Statement

Can I pass table name as parameter in prepared Statement

I have another way to make sql query in programing but i have a case where i have limitation of that thing so please tell me is it possible with prepared Statment SetXXx methods or not ?
Thanks

Well, I would say (ugly as it is) String concatenation, or stored procedures.

Passing form field name to the subject line of the task assign email

Hello Everyone,
I am trying to create a process that need to pass one of the field data from a form to the task email assign but could not make it work right as expected. I think I miss something but could not figure it out myself. If any one has done this before, please share your knowledge.
Thanks in advance,
Han Dao

Hi Jasmin,
I thought it simple thing to do by passing the xPath to the subject line but for some reasons, it does not work instead it show the whole xpath on the subject line. Here is my xpath:
{$/process_data/FormData/object/data/xdp/datasets/data/FSFIELDS_/Form1936/EmpInfoSub/UserM gr$}
where Form1936 is the pageName, EmpInfoSub is sub-form, and UserMgr is field name on the form.
Thanks,

Pass multiple values as single input parameter into pipelined function

Hi all,
My need is to pass multiple values as single input parameter into pipelined function.
For example - "2" and "3" are values of input parameter "t":
with data as (
select 1 as t from dual union all
select 2 as t from dual union all
select 3 as t from dual union all
select 4 as t from dual union all
select 5 as t from dual
select * from data where t in (2,3)Is it possible at all?

Not exactly sure, but usually 'multiple values'+'pipelined function' = some IN-LIST related approach?
See:
SQL> create table data as
2 select 1 as t from dual union all
3 select 2 as t from dual union all
4 select 3 as t from dual union all
5 select 4 as t from dual union all

Write a query for which has its field name as input parameter

Hi All,
I need to write a query for SSRS report. StartDate, EndDate and ChangedField are the input parameters.
Let's consider that we are taking employee details. The table contains lot of fields like emp name,add1,add2,city,state,country,designation,rank etc. We have almost 30 fields are there. These field name are coming as input parameter "ChangedField"
. I need to show the records which belong to the start date and end date also data change for the field which is given in the input parameter "ChangedField". That meand If I give ChangedField="city", we need to check for data which
has been updated with new City name in the given time period.
Please suggest.
Regards,
Julie

Hi Julie,
Per my understanding that you have many fields in the table to be displayed in the report, some of the fields will always show and others should be hide and show based on the selection of the parameters which include the columns names, right?
By default, we can't display columns dynamically in the report automatically without insert this column in the report before. So, in your scenario, I will suggest you to add all the columns in the reports first and then add show/hide expression on
the column visibility based on the selection of the parameter "ChangedField", when some of the fields selectted they will be display, otherwise they will be hidden. For the fields which you want to be always displayed will not need to add the expression
in the column visibility.
Details steps about how to acheive this, please referencet to the article below:
Displaying Dynamic Columns in SSRS Report
If you still have any problem, please feel free to ask.

Adding a CM: Invalid length parameter passed to the RIGHT function. (CINF)

We started seeing this error message a week ago when attempting to add a Credit Memo. We only see this error message when entering Credit Memos and not any other finacial documents. I've done some preliminary research and haven't really come up with anything to point to the issue. Prior to reporting this to my support partner, I wanted to see if anybody here has seen this before or give me some ideas to look into the source of the issue.
Full error message: Microsoft SQL Native Client SQL Server Invalid length parameter passed to the RIGHT function. (CINF)

Checking the list of form ID's at [http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/892] shows the A/R Credit Memo as 179 and the A/P Credit Memo as 181. This also corresponds with what I see when viewing the system information on the form.
