Hello experts,
I am creating an ALV report where i need to pass the column names dynamically. if the current month is March and year is 2009. the column names should be as below
March 2009 April 2009 May 2009 June 2009 ..............till Feb 2010 (total columns are 12)
if the current month is June and year is 2010 it shoud be displayed as
June 2010 July 2010 Aug 2010................till May2011
I am actually calculating the forecast qty for each month and displaying in a report from the current month.
How to write field catelog for this requirement?
Thanks in Advance.
Rajesh.

I think in the fieldcat, at the time of declearation, you can alter the field description depending on the present month.
If present_month = January
wa_fieldcat-reptext_ddic = 'January'. " Field description
elseif present month = February.
wa_fieldcat-reptext_ddic = 'February'. " Field description
on so on.....................

Execute immediate with using clause to pass column name dynamically

Hai,
Is there any way using execute immeidate to pass the column name dynamically. I used to pass the column value as dynamic with the help of "Using clause" . But if i use to pass column name, it is giving numberic error at run time. Eg,. for testing has been given below.
1. Column value as dynamic, which is working correctly.
create or replace function testexeimm (acctnum char)
return number as
acctbal number;
begin
execute immediate 'select balance from acct_master where acct_no=:a' into acctbal using acctnum;
return acctbal;
end;
2. Column name as dynamic which is not working
create or replace function testexeimm (colnam char)
return char as
acctbal char;
begin
execute immediate 'select :a from ch_acct_mast where rownum=1' into acctbal using colnam;
return acctbal;
end;
Any help in this regard will be highly appericated.
Regards
Sridhar

So the variable has to be numeric too:
create or replace function testexeimm (colnam char)
return number as
acctbal number;
begin
execute immediate 'select '|||colnam||' from ch_acct_mast where rownum=1' into acctbal;
return acctbal;
end;Max

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');

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

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.

thanks for your reply
i 'm doing what exactly you mention here .
my problem here is
i have 15 columns
i am executing a query based on the values of the column(column name) in the target page
1)here i am passing(all) the column values to the next page-but i want to pass only one column values(column name)
when i click on any cell of that column
OR
2)i can pass all column name to target page -there(in the target page) i can filter out
i think option 1 would good if you filter out the unwanted columns

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

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;

HTML DB Chang column name dynamically

Can I change the column name dynamically. for instance
Today run my apply it will display the title of the columns this
Column title: Wed Thu Fri
04/22/05 04/23/05 04/24/05
Data 45 34 34
54 56 23
Next week
Column title: Wed Thu Fri
05/03/05 05/04/05 05/05/05
45 34 34
54 56 23
The date Change Dynamically?

Go to your report and open report atributes. There you can choose the options for column names. Click on the pl/sql function and type this in:
DECLARE v varchar2(20);
begin
v := to_char(SYSDATE, 'dd.mm.yy')||':'||to_char(SYSDATE+1, 'dd.mm.yy');
RETURN v;
END;
This will set the first two columns to the specified dates. You can use this as one option.
If the case is more complicated than you can do the following:
1. create a number of items on your page - hidden
2. compute the items with values once the page is loaded
3. use item substitute string &ITEM. in the column name, which will use the item value as a name for the column.
This way you are more flexible since you can use the item values for some columns only and have the other columns hardcoded.

Column names dynamically in Dynamic SQL

Hi All,
We can use Table Name dynamically in Dynamic SQL.
Can we use column names dynamically?
Thanks,
Umasankar

Hi Todd Barry,
Thanks lot for your immediate response.
Could you please tell me, how can we use column name dynamically?
I tried but, I didnt get the correct result.
Here is my coding.
Declare
SQL_String Varchar2(2000);
Category varchar2(50):= 'ELECTRO_PLATING_413';
Type ConstCurTyp is REF CURSOR;
Const_Cv ConstCurTyp;
vLab_name varchar2(80);
Begin
Execute Immediate 'Truncate table tto_lab_names';
dbms_output.put_line(category);
dbms_output.put_line(' ');
SQL_String := 'Select lab_name from tto_constituents where :category is not null';
Open Const_cv for SQL_String using category;
Loop
Fetch Const_Cv into vLab_Name;
Exit When Const_Cv%NotFound;
Insert into lab_names values(vLab_name);
End Loop;
Commit;
Close Const_Cv;
End;
I am getting all the lab_names as result.
Thanks,

Dynamic Column Name on Interactive Report

Hi all,
Is it possible to assign a SQL result to a Column name on an interactive report?
I have been able to do this on a standard SQL Report though the use of page items but have not had much luck with interactive reports.
Any help is appeciated.
Thanks,
Dan

could you please explain step 4 a bit more?
as with the standard report, i just created an item with SQL query with a corresponding computation with same SQL query and that works great.
i tried the same method with interactive and it did not work.
in step 4 it mentions creating a process to populate the items.
how is this done?
Thanks,
Dan

Passing column names in as a variable

I know in SQL server there is a way you can pass a variable in to the procedure and put that variable as a column name, Oracle doesn't seem to pick the variable up as a column name. Can anyone show me how with a simple select statement

bgulcu wrote:
I'm having a similar problem. I didn't want to open up another thread since it's related.
Problem:
I have 107 columns on a table. The number of columns increases almost every month.
I have an array of columns, which I have gathered from the db. I need to pivot the whole table, but due to indefinite number of columns, it had to be dynamic sql.
Premature Solution:
Right now, the solution that we have runs through the array of columns and uses dynamic sql to query for every single cell to get the value. Considering that we have 1000+ rows on this table, in order to do the transformation, we send 107000+ queries which is just ugly. It works, but I don't feel comfortable about it.
Solution:
Since we are able to get a single row of 107 columns, why don't we gather the whole row, and get the information out from it instead of tiring up the server? The indefinite number of columns is a problem, but we have the whole list in an array, lets say feature_array. So what I want to do is to get the date from the row, ie myRow.feature_array(1), myRow.feature_array(2), ..., myRow.feature_array(i).
I just learned that it's not possible to do it (from this thread).You just misunderstood the contents of this thread. What we said is that you can't do such things with static SQL, so you need to use dynamic sql.
What has also been told was that using dynamic sql for such a purpose is just the result of a bad design. Use a relational table as a bi-dimensional array is not right, it is possible but it's not right for the simple reason that you need a procedural language to process the dynamic SQL that is needed to retrieve data.
Probably on database programming there's only a rule of thumb and it says: "Maximize SQL minimize PL/SQL" (or any procedural language like java). The only exceptions to keep code in procedural language must depend on a complexity reduction determined by its use. In your case there is no complexity reduction determined by the use of a procedural language.
In the thread on this link(Schema integrity I discussed about how to implement a solution you can use as alternative for submitting queries with variable column names.
If you introduce parameter management in your model probably you could have your problem solved with the use of only a single SQL statement. And that may be a good designed model.

Passing INLCUDE name dynamically

Hi,
Is there any way of passing the INCLUDE name dynamically?
Scenario is as follows
Requirement is to consolidate approx 6 enhancements (user exits) of the same name from 6 different systems into 1system . Objective is to put each of the code in an INCLUDE and then call the relevant INCLUDE based on some data maintained in a z-table
Z-table would have entries like this
Scenario      Include
S1                I1
S2                I2
S3                I3
Hence final enhancement code should read the entry from z-table and accordingly pass the relevant INCLUDE name
INCLUDE <include name from z-table>
Valuable suggestions are needed.
Poonam

Hi Poonam,
<li> Create one function group.
<li> Write your 6 includes code in 6 function modules. function module is nothing but include in Function group.
<li>Try to give importing and exporting parameters are same.
<li>Try the below way.
REPORT ZTEST_NOTEPAD.
DATA: BEGIN OF IT_FUNC OCCURS 0,
        NAME TYPE RS38L-NAME,
      END OF IT_FUNC.
"Build your it_func with function modules.
LOOP AT IT_FUNC.
CALL FUNCTION IT_FUNC-NAME "You can call fm dynamically
    EXPORTING
      DAY_IN            = IMPORTING
      LAST_DAY_OF_MONTH = EXCEPTIONS
      DAY_IN_NO_DATE    = 1
      OTHERS            = 2.
IF SY-SUBRC <> 0.
    MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

Passing Display Name to Portlet(report) as a parameter???

Does anyone know if we can pass the Display Name for a report dynamically to the portlets?
For now, I have had to create one page for each report(portlet) by Overwriting the report display
option and using specific Query Option for each portlet. Preferably I would just call the report
with two parameters, one used in the sql to narrow down the query and the second for the Display
Name.
Thanks in advance,
