Passing Column name(String) in setting CallableStatement

Is it possible to pass Column Name while setting the CallableStatement while using drivers for JDK 1.4, if yes how do I do it.
Thanks!

You don't necessarily need to use dynamic SQL;
create or replace procedure p
p_a number default null,
p_b number default null,
p_c number default null
) is
begin
insert into t
values
    (p_a, p_b, p_c);
end;
Procedure createdUsing named notation;
exec p(p_a =>1, p_c => 3);
PL/SQL procedure successfully completed
exec p(p_b =>20, p_c => 30);
PL/SQL procedure successfully completedPassing NULLs;
exec p(4, null, 6);
PL/SQL procedure successfully completed
exec p(40, 50, null);
PL/SQL procedure successfully completed
select * from t;
         A          B          C
         1                     3
                   20         30

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;

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

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

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.

How to write field catelog for this requirement?
Thanks in Advance.

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.....................

How to pass column name in slect statement in query

hi,
i want to make a report where in query select statement using variable as a column name. but its not working plz guide me how can i do this.
i have created a function which return column name through variable & that variable i want to to use in select statement
select :m1 from table1;
regards

Hi,
Create a user parameter (say P_field), and assign a valid field name as initial value (say NAME), And In the Query, write
SELECT CODE, &P_field FN_FIELD FROM <table_name> WHERE <condition>And in the BEFORE PARAMETER FORM Trigger under the Report Triggers, write,
function BeforePForm return boolean is
begin
:P_field := <your_function_call>;
return (TRUE);
end;And use that FN_FIELD field in the report.
Hope this will clear your issue.

Passing column name inside an update query

Hi,
To checking if there any number field present in 'ID' column, I am using the follwing query.
UPDATE table1
SET COL1 = 'Y'
WHERE 0 = (
SELECT CASE
WHEN ID IS NULL THEN 1
WHEN REGEXP_LIKE(
ID,
'^( *)(\+|-)?((\d*[' || SUBSTR(VALUE,1,1) || ']?\d+)|(\d+[' ||

) THEN 1
ELSE 0
END
FROM NLS_SESSION_PARAMETERS
WHERE PARAMETER = 'NLS_NUMERIC_CHARACTERS'
Now I need to extend this query to check 10 more columns from table1. How can modify the above query to pass that 10 columns the above query.

Got it ! Then again your syntax is incorrect... You should use correlated subquerry

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

Column Name change in IR

Hi,
I want to display the different column name in dashboard other than the column name in result set. for eg: I have the results with column name emp_id. now i want to display this column name as Employee_ID in dashboard. How to do this?
Thanks in Advance...

Either change the column name in the Query on the Request Line it does not impact the column selected similar to the SQL Select statement AS
OR
Add a Computed Column in Results referencing emp_id and then Hide emp_id.

JDBC ResultSet lowercase Column names

Hi,
My group has a body of DBMS access beans which use lowercase column names for result set get(s)* ..ie rs.getString("empno");.
Are current JDBC context uses KIVA\NAS.
We've recently attempted to use these beans under Oracle JDBC OCI (type 2). We've noticed that Oracle JDBC prefers rs.getString("EMPNO") .. or rs.getString(1).
Is there a way around this? Or do we have some serious changing to do?
Thanks in advance.

The column names our current driver takes in getString() is not case-sensitive. I am not sure whether that was the case with some previous versions. Is it possible that you can try it on the 8.1.6 driver?

If i use variable X then i am able to see only the literal
string in the output. BUT if i put cursor name.coulmname,
then the resumt (XML) is fine.I wanted acheive this
dynamically just like execute Immediate

My scenario is little different, let me explain:
My columns will remain same but values changes (based on column formula) according to the selected prompt value
If I select 'Oct' from prompt then
Curr will contain data for 'Oct' only
Next1 will contain data for 'Nov' only
Next2 will contain data for 'Dec' only
Next3 will contain data for 'Jan' of next year only.
Later if I select 'Jul' from prompt then
Curr will contain data for 'Jul' only
Next1 will contain data for 'Aug' only
Next2 will contain data for 'Sep' only
Next3 will contain data for 'Oct' only.
I don't have different columns for each months but the columns are capable to reflect data for any month.
So, how can I reflect the column name as month name for which that contains data.

S Anand
