Column name as item in lov - parameter passing

Hello Eveyone,
Currently i am working on a requirement where the user will choose any one of the column of the database as parameter. Means all the column names should come in LOV. Once he selects the column he has to choose the operator(>,<,=,<>) in another LOV after that user enters value. Can anyone please guide me on this. Please let me know is it possible in crystal?
Thanks
Yash

It would be incredibly complex as you would have to hard code a massive if then else select formula based on the two parameters selected. You could do something with adhoc reporting in Crystal Enterprise or BOXI. But do do this with a single Crystal report would be very difficult.
You should be asking
"Why on earth does anyone want such flexibility?"
Sounds like user does not know what they want and is making an impossible request.

Automatic Report Bursting based on column names given by user as parameter.

Hi,
Could some help me achieve the following functionality. The requirement are:
1. create a report that has parameters that are column names (display values e.g: department, location, employee job code)
2. the end user will select one or more columns from the multi-select parameter
3. we want that there should be a button on clicking that the user should get automatic file bursting. He should not be required to go to schedules tab and create a new job for that.
4. the report should burst to a file location depending on the columns selected by the user, e.g. if user selected department and location then we should have files saved in the set file location as sales-india.pdf, sales-us.pdf, hr-india.pdf, hr-us.pdf and so on.
I am new to BI Publisher.
Could you help me in creating such a parameter, what should be report sql for capturing the data from parameter and then doing report bursting automatically based on two or more parameter values given by the user.
There is no need to show the report to the user in BI Publisher as there are thousands of rows in a table. Three tables join to give the employee data.
-Priyanka

Thanks for a quick response but I am still not clear on
1. how to do this using custom java code
and
2. actually user would login to interactive dashboard and there he will give these parameters using which we need to automatically burst a BI publisher report. Can this be done some how?

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

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.

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

Problem with long column names

I'm trying to fetch rows via pl/sql from an Access db table that has long(over 30 characters) column names. I've tried using pass-through sql but it still returns generic ODBC error. Is there a way to get this to work without changing column names in table?

Andy,
Oracle does have a restriction in column name size but if you are using pass-through this should not come into play.
It may be a restriction of the ODBC driver or a bug. Please take a look at the ODBC driver trace file.

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);

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.

Passing a column name as a parameter

Good afternoon,
I was wondering if any of you ever encountered the following situation and found a method to get around it...
I recently created a pivot table using the SQL Query (PL/SQL function body returning SQL query) option.
The table consisted of the following information:
- Date range, Object Type and count.
The final table looks something like this (pardon the lack of fancy markup, hopefully it will get the point across):
Date        Object A    Object B    Object D    Object G
01-apr-09   10           16         50          43
02-apr-09   1            15         77          35
03-apr-09   19           0          14          17
04-apr-09   15           7          70          20
05-apr-09   7            6          65          50And it goes on like that.
I had to create the code dynamically because I don't know what Objects I will get in any given date range (for example: I could have something for Object C and nothing for Object D in the month of March). I had a cursor loop through the object types before creating the SQL query that builds the table above.
The table is now working fine. What I'm trying to do now is do a little bit of drilling down in data.
Since everything is dynamically built, I can't give actual column names in my report. Is there any way that, when I click on, for example, the "10" on April 1st in Object A that the column header "Object A" gets passed? #COL02# only passes the value "10" which isn't what I want, and I tried the other variations such as :COL02 and &COL02. without much luck.
If you could shed some light on this problem, that would be greatly appreciated!
Thank you for your time.

Hi,
You can achieve passing column name as parameter with the help of jquery.
Below is the sample code
<script src="http://www.google.com/jsapi"></script>
<script type="text/javascript">
   google.load("jquery", "1.2.6");
</script>
<script type="text/javascript">
    //<![CDATA[
    $(document).ready( function() {
        $('.t20data').each( function(i) {
            $td =$(this);
            colHeader = $(this).attr("headers");
            $td.html('<a href="f?p=' + &APP_ID. + ':3' + ':' + &APP_SESSION. + '::NO:3:P3_COLUMN_HEADER,P3_COLUMN_VALUE:' + colHeader +',' +$td.text()+ '">' + $td.html() + '</a>');
    });                                  //]]>
</script>Note - U need to change t20data , :p3_column_header , :p3_column_value to match you application.
No need to add link individually by going into column attributes

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;

Parameter as column name

Hi all,
I want to pass a parameter value as a column name in my where clause, like this:
where table.(:parameter1)=:parameter2can this be done??
Thanks,
Magnus

Hi,
No, not this way. A bind variable can only be used with values, not identifier.
You'll have to use dynamic SQL to build and execute your query.
For example :
DECLARE
col_name VARCHAR2(30) := :parameter1;
sqlstr VARCHAR2(100) := 'SELECT col1 FROM sample_table WHERE '|| col_name ||' = :1';
val sample_table.col1%type;
BEGIN
execute immediate sqlstr into val using :parameter2;
END;Edited by: odie_63 on 5 mai 2010 12:09 - added example

Order query depending on column names passed at runtime

Hi
Can any one suggest how to order by at run time depending on column name passed as parameter.
create or replace procedure dummy_proc( p_orderby varchar2,p_refcursor out sys_refcursor)
is
begin
     open p_refcursor for select * from
     emp where Status='A'
          order by (select p_orderby from dual);
end;
--execution part for testing
declare
     v_outcursor sys_refcursor;
     v_rec_data emp%rowtype;
     v_cnt number;
begin
     dummy_proc ('ename,sal',v_outcursor);
     begin
          loop
               fetch v_outcursor into v_rec_data;
               v_cnt:=v_outcursor%rowcount;
               exit when v_outcursor%notfound;
               dbms_output.put_line('empno '|| to_char(v_rec_data.empno));
               dbms_output.put_line('empno '|| v_rec_data.ename);
          end loop;
     end;
     dbms_output.put_line('Count is'|| to_char(v_cnt));
end;
we do not want to something like below as my actual query is very big with union statements and case expressions, (below is just an similar example)
how i tried to order by but its not working.
v_sql='select * from emp where empno= '|| p_empno || ' order by '|| p_orderby;
open p_refcursor for v_sql;
Thanks in advance
Vishal

v_sql='select * from emp where empno= '|| p_empno ||
' order by '|| p_orderby;
open p_refcursor for v_sql;I agree, you really don't want to do that, you want to use BIND VARIABLES.
v_sql := ' select * from emp where empno = :bound_empno order by :bound_orderby';
open p_refcursor for v_sql using p_empno, p_orderby;
[pre]
The size of the statement shouldn't come in to play, if the only dynamic portion of it is the order by clause then declare a constant which is the large query (you can use a LONG datatype) and then concatenate in the order by clause before you return the reference cursor.
Unless you can give a legitimate reason for why you cannot use Dynamic SQL (not why you do not want to use it) this would be my approach.
And please, if you don't know what a bind variable is...read about them, or your system will suffer.

Selecting an lov parameter value sometimes not passed correctly

When selecting a value from an LOV parameter, sometimes the parameter value doesn't seem to get passed correctly to the data template query.
For example, let's say I have the following LOV parameter called "risk":
Some Risk
New Risk
Other Risk
Last Risk
When I select "Some Risk", I would get correct results and when viewing the "Data" xml, I can see the parameter with the right value:
<RISK>Some Risk</RISK>
But when I select "New Risk" the results are incorrect and the xml shows:
<RISK />
as if the value was not passed as the bind parameter value for the dataset query.
Any idea what I'm doing wrong? Is this a BIP bug or is there a workaround?

Hi, thanks for the reply.
The LOV is of "SQL Query" type (not fixed data) and the values were retrieved from the database.
Supposing this was the sql query for my "risk" parameter LOV:
select dimvaltl.GENERIC_VAL_NAME
from GENERIC_VAL_TL dimvaltl,
GENERIC_TL dimtl
where dimtl.GENERIC_NAME = 'Risk'
and dimvaltl.GENERIC_ID = dimtl.GENERIC_ID
order by dimvaltl.GENERIC_VAL_NAME
And supposing this was the sql query in the data template dataset:
select pdimv.ID
from GENERIC_V pdimv
where pdimv.NAME = 'Risk'
and pdimv.VALUE in (:risk)))
If risk is empty, obviously the query would not work. I noticed the xml generated sometimes show the selected parameter value and sometimes don't, as if BIP is not passing it to the dataset query as bind parameter value.
Incidentally I have other lov parameters that works fine, the only difference I can think of is that for this LOV query I am doing a join instead of a simple select statement from one table.

Can we use Column Names in Parameter Cursor

Hi
can we use Column Names in Parameter Cursor??
DECLARE
CURSOR Emp_Cur (P_Deptno NUMBER)
IS
SELECT Empno, Ename
FROM Emp
WHERE Deptno = P_Deptno;
BEGIN
FOR Emp IN Emp_Cur(10)
LOOP
DBMS_OUTPUT.PUT_LINE('The Employee Number is: '||emp.Empno);
DBMS_OUTPUT.PUT_LINE('The Employee Name is: '||emp.Ename);
END LOOP;
FOR Emp IN Emp_Cur(20)
LOOP
DBMS_OUTPUT.PUT_LINE('The Employee Number is: '||emp.Empno);
DBMS_OUTPUT.PUT_LINE('The Employee Name is: '||emp.Ename);
END LOOP;
END;
In the above Program, I send Deptnumber. If i send Column names like Empno, Ename. What can i do??
If Declare Samething Through Parameter Cursor, it doesn't accept VARCHAR2(Size)

For parameters you don't use size, just the type (DATE, NUMBER, VARCHAR2, CLOB, ...)
DECLARE
CURSOR Emp_Cur (P_Ename VARCHAR2)
IS
    SELECT Empno, Ename
    FROM Emp
    WHERE Ename = P_Ename;
BEGIN
FOR Emp IN Emp_Cur('SCOTT')
LOOP
    DBMS_OUTPUT.PUT_LINE('The Employee Number is: '||emp.Empno);
    DBMS_OUTPUT.PUT_LINE('The Employee Name is: '||emp.Ename);
END LOOP;
END;

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
