Problems with query with more than 20 values in the select clause

I have a region based on a function returning a SQL query. It needs to have more than 20 values in the select clause. When I run the page I get a no data found error in the region. I managed to reproduce this behavior with just the following as the select returned by the function:
select 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21
from dual
I am running the 1.3.9.00.15 release of Marvel on 9.2.0.2 of the db on Solaris.

Hello Raju,
I will email you the connection settings when I return to the office.
One thing I should have mentioned: The sql string is returned from a package in the db, so the query region text I originally posted isn't quite correct.
it is something like:
declare
begin
return my_pkg.my_fnc;
end;
the stored package is nothing more than:
package my_pks is
funtion my_fnc(i_test_param in varchar2) is
begin
return 'select 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20, 21 from dual';
end;
end;
Sorry for the inaccurate info in the first post, but I am away from the server in question right now.

Essbase Variable with more than a value for use after in Planning forms.

I want to now if it would be possible to create a variable with more than a value for use after in Planning forms.
The variable that I want to use is created in Essbase.
Example:
&Years = FY08,FY09,FY10

Hi.
The only workaround I know for the problem is to create parent in the dimension.
In your case, create member “planyears”.
Then you define children that are shard (this are the multiple member for the variables FY08, FY09 etc..)
Create Essbase sub variable that will have 1 member value “planyears”
When you use the Sub Variable in form select function “Children” and in that case it will use the member FY08,FY09 etc on the form.
Limitation: I’m working on version 9.2.0.3 so you can’t create hierarchy in the year dimension, but you can use it in other dimension.

URGENT: passing more than one value at the same parameter

Hello friends at www.oracle.com,
if I have a Forms program that sends some parameters to a Report, how can I send more than one value at the same parameter that is being sent?
For example: the Reports parameter P_CODE should receive (from Forms) and print the values 1, 2, 3 and 4, each one in a different page. But, only 4 is being printed, and these values aren't saved at a database, so I have to pass the other three values too. How can I solve this problem?
This is quite urgent and I need help on this.
Best regards,
Franklin Gongalves Jr.

Thanks to Oracle Reports Team for answering! I'm sure this will work.
Best regards,

[email protected]
hello,
on the forms side, you will have to build the list for this parameter by e.g. string concat.
on the reports side you will have to "decode" this parameter according to how you built it in forms.
e.g. if you pass the list like this "10~20~30" you might use a where-clause in the query
... where instr(myCol, :myParam) >0

Performance problem with more than one COUNT(DISTINCT ...) in a query

Hi,
(I hope this is the good forum).
In the following query, I have 2 Count Distinct on 2 different fields of the same table. Execution time is okay (2 s) with one or the other COUNT(DISCTINCT ...) in the SELECT clause, but is not tolerable (12 s) with both together in the query! I have
a similar case with 3 counts: 4 s each, 36 s when together!
I've looked at the execution plan, and it seems that with two count distinct, SQL server sorts the table twice before joining the results.
I do not have much experience with SQL server optimization, and I don't know what to improve and how. The SQL is generated by Business Objects, I have few possibilities to tune it. The most direct way would be to execute 2 different queries, but I'd like
to avoid it.
Any advice?

IN operator with more than 1000 values

Hi,
For a given list of IDs (PKs), I need to fetch the corresponding rows.
The problem is that I have more than 1000 values and as far as I know that IN operator is limited to 1000
values.
I thought about using UNION such that each Select contains up to 1000 IDs.
example":
select * from temp where id in(1....1000)
union all
select * from temp where id in(1001....2000)
Is there a better way to do that?
Thanks
dyahav

As others have presented technical solutions, i'll present you a logical one (seemingly logical anyways, but it will depend on your application).
I have seen some applications where you get
select * from some_table where ... <conditions>;That result set is returned to the front end and presented to the users who then pick a series of records and submit another request to the database which ends up being...
--note, this could be a many table join, with lots more information that just the some_table, this is illustrative only
select * from some_table where pk_value in (super_super_duper_list_based_on_last_result_set);If this mimics what you have in your application, i'd recommend just fixing it so the users can select a reasonable set of data, OR the entire set (in the last case you'd just send the <conditions> instead of a massive list of PK values).
Again, highly speculative but i thought i'd mention it in the off chance it's useful to you.

Problem with more than one item in a track

DVDSP 4.0.2 / OSX.4.2 I've built a DVD with several tracks. In each track I've placed several .m2v files, one after another. Finished build plays fine on my Mac and on one of my stand alone DVD players. But on another stand alone (Sony DVP-S360) something very odd happens. DVD begins to play just fine, but whenever it encounters a track with more than one source file, it will play until it gets to the spot in the program where the second source file is in the track and then it hangs and won't do anything. I'm just curious if anyone has any insight into this problem. Is it a DVDSP conflict thing with certain players? Or is this Sony player just not capable of playing a DVD built this way? Thanks.

This page here:
http://www.videohelp.com/dvdplayers.php?DVDnameid=428&Search=Search&
has someone talking about finally getting burned DVDs to work, which suggests they previously had problems. I can't think why the track would not seem like continuous video, as if it had always been that way. Our Sony DVD player at work seems sensitive to higher data rates. What data rate did you use?

How can we create a table with more than 64 fields in the default DB?

Dear sirs,
I am taking part in the process of migrating a J2ee application from JBoss to SAP Server. I have imported the ejb project.
I have an entity bean with 79 CMP fields. i have created the bean and created the table for the same also. but when i tried to build the dictionary, i am getting an error message as given below,
"Dictionary Generation: DB2:checkNumberOfColumns (primary key of table IMP_MANDANT): number of columns (79) greater than allowed maximum (64) IMP_MANDANT.dtdbtable MyAtlasDictionary/src/packages"
Is it mean that we can not create tables with fields more than 64?
How can i create tables with more than 64 fields?
Kindly help,

How to send more than one value to the Jump target report variable screen.

Hi,
I have two reports with Plant variable on their input variable screens. Say this Plant can take two values X and Y. The first report is executed with Plant value X and displays data. When a jump is made to report two, Plant value X is retrievd into report two's plant varible value. Now how to send value Y also to Report two when jump is made. I think we can do it with a customer exit? Any help is appreciated
Thanks
Bhanu

Hi Bhanu,
I guess u have created a Variable with Sinlge value ,So Create a Variable which has Multiple Sinlge Values or Interval so that u can have more than one value and if u hvae more than value u will get data for those values and when u do a jump then u can see the data in the JUMP query for both the Values of Input.

Gantt Chart: Problems with more than 39 elements

Hi all,
I have a problem with Gantt Project Chart.
Please have a look at http://tryapexnow.com/apex/f?p=2141:2 (credentials: demo/demo)
If you limit to 39 rows this works fine, but with 40 rows or more the timeline is not in line with the datagrid.
Strange thing is that as soon as you collapse all tasks the timeline is correct.
Uncollapsing brings back wrong display.
Has anybody seen this behaviour before and can help me out on that?
Thanks for help,
Moritz
Edited by: commi235 on 31.05.2011 13:23

Hello Moritz,
the "Maximum Rows"-option is as default set to 40.
if you created the chart by "Create Region => Chart => Flash Chart => ..." you can change this value in tab "Chart Series", below the "Build Query"-button.
But I don't know how to change the maximum number of rows, when the chart is created via
"var chart = new AnyChart(''#IMAGE_PREFIX#flashchart/anygantt_4/swf/AnyGantt.swf''); " in a HTML-region.
I'm very interested in finding a solution.

How to pass a parameter with more than one value to a report? (urgent)

Hi, all
I try to pass a parameter from a search form to a report in
which I would like to print out my search result. My problem is
I can pass the parameter to report but only one value which my
cursor points to. could anyone tell me how to pass a list of
value to the report? my trigger in form like this:
declare
PL_ID PARAMLIST;
sc_no books.c_no%type;
begin
PL_ID := GET_PARAMETER_LIST('parametername');
IF NOT ID_NULL(PL_ID) THEN
DESTROY_PARAMETER_LIST(PL_ID);
END IF;
PL_ID := CREATE_PARAMETER_LIST('parametername');
IF ID_NULL(PL_ID) THEN
MESSAGE('PL/SQL held against Button failed to execute');
RAISE FORM_TRIGGER_FAILURE;
END IF;
ADD_PARAMETER(PL_ID, 'PARAMFORM', TEXT_PARAMETER,'NO');
sc_no := :searchlist.c_no; --(c_no is the value I want to pass
but not only one.)
ADD_PARAMETER(PL_ID, 'pamametername', TEXT_PARAMETER, sc_no);
RUN_PRODUCT(REPORTS, 'reportpathname.rep', SYNCHRONOUS, RUNTIME,
FILESYSTEM, PL_ID, NULL);
end;
Thank you in advance
Diana

Is it your values in parameter NO separated by coma? And is it
parameter in where clause?
Do you want something like :
from table
where s_no in (NO) ?
If is answer "yes" you can create lexical parameter in report.
You can write in report sowething like:
select a.field1, a.field2,.....
from table a
&COND /* this is if is condition only one line after "from".
if you have more lien after where then you will put this &COND
in line where you want to have your multivalue.
Then in your trigger in form you should write:
sc_no := 'where a.sc_no in ('||:searchlist.c_no||')';
ADD_PARAMETER(PL_ID, 'pamametername', TEXT_PARAMETER, sc_no);
/* again this is if you have only one line with WHERE ili
conditions */
or you will write:
sc_no := 'and a.sc_no in ('||:searchlist.c_no||')';
ADD_PARAMETER(PL_ID, 'pamametername', TEXT_PARAMETER, sc_no);
It will substitute line in which is your conditions with
multivalue.

Search Help with more than one value back

Dear Experts,
We added two customer fields to the SC.
For the first customer field we created Search Help.
When picking any option from the search help we need TWO values back u2013 one value to the first customer (the field with the search help) and the second value to the second customer field (the field without the search help).
Can you please advice how can we have TWO values back from the search help?

Can't access ejb with more than 1 person at the same time?

I am using the ejb to access the database using DBConnection Pool that I find in book. The code is as follow:
The problem is when more than one user access almost at the same time, the one who enter frst can access, but the other one can't and return context lookup error in creating EJB.
What's the problem of it, is it the ejb concurrent access problem or database concurrent access problem?

Hi,
static synchronized public DBConnectionManager getInstance() {
The word "synchronized" will allow only one user at a time to access the getInstance() method which returns DBConnectionManager. Suggest u read some stuff on the same
As I am not sure which App server ur using, u cld do the following
1. Create a Conection Pool in ur App Server itself (Weblogic/Websphere/Jboss way)
2. Create a DataSource which maps to this Connection Pool.
3. Use the DataSource object which handles poolong of Connections to access the database
4. As mentioned above, Read notes/documents on "Synchronized" and "Vector" before you use this word in any code of EJB. This will solve ur problem. Read topic called "Collection Framework".

SQL select query having more than 1000 values in 'IN' clause of predicate.

Hi,
We are executing a select query from a table and showing it through a front end screen. When the count of values given in the 'IN' clause of predicate are exceeding 1000 , it is throwing error.
eg. select * from Employees where emp.Id. in('111',123','121','3232',........1001 Ids)
We are using Oracle version 10.2.0.
Please suggest how to tackle such issue.
Regards,

Use a nested table:
create or replace type numbertype
as object
(nr number(20,10) )
create or replace type number_table
as table of numbertype
create or replace procedure tableselect
( p_numbers in number_table
, p_ref_result out sys_refcursor)
is
begin
open p_ref_result for
     select *
{noformat}     from   employees
     ,        (select /*+ cardinality(tab 10) */ tab.nr
               from   table(p_numbers) tab) tbnrs
     where id = tbnrs.nr;
end;
/{noformat}
Using nested tables will reduce the amount of parsing because the sql statement uses binded variables! The cardinality hint causes Oracle to use the index on employees.id.
