Ref cursor in Reports details
Hi All
we are planning to create a D2K report using
ref cursor the problem for me is that i want to know
whether it is feasible for creating a report which
contains around 5 complicated queries and number of
formula columns etc.can you please give me points
how to go about or if it is not feasible can you
give me the reasons for that.
Hello,
Ref Cursor queries are useful in sharing queries across reports, and exploiting commonality between them. You can segregate your individual queries into ref cursors and combine them in your data model. You can also create formula columns based on data fetched by the ref cursor, since Reports treats any data fetched from the data source in a generic manner.
Please take a look at the 'Building a Paper Report with Ref Cursors' section of the 'Building Reports' manual on OTN at http://otn.oracle.com/products/reports/htdocs/getstart/docs/B10310_01/orbr_refcur.htm#1009556 for further details on building and using ref cursor reports.
Thanks,
The Oracle Reports Team.

I have developed a report (REPORTS 3.0.5.8)based on REF Cursor
Query. I Created a local Package and called the function in the
package in the QR_1RefCurDS function. I am able to get the
results when I tried to run from my machine.
The report was compiled, saved and generated and copied the REP
file on to a different machine on the N/W.
But when I tried to access the same report over the network, it
fails giving the following error:
REP-1401: 'beforereport': Fatal PL/SQL error occured.
ORA-06508: PL/SQL: could not find the program unit being called.
Runtime Engine and REP file reside on a single machine and I
access the report in the following format:
//Computer Name/Oracle_Home/Bin/R30RUN32.EXE //Computer
Name/D/ReportName.Rep userid/password@SID
I have been unsuccessful after trying to move the package to the
database(I get a Virtual memory error ! !)
Is there any other way to accomplish the same task(dynamic
changing of the SQL statements) ?? Is LEXICAL Parameters is the
only answer apart from the REF Cursor which does not work ?????
Database:
Oracle Server Release 7.3.4.3.0
Oracle PL/SQL V2.3.4.3.0 Production Release
Reports 3.0.5.8:
Oracle Server Release 7.3.4.0.0
Oracle PL/SQL V2.3.4.0.0 Production Release
Does this make a difference ????

Converting cursor to ref cursor in Report builder pl/sql
Hi,
I am trying to use dynamic sql in My report 's pl/sql code.
I can not use execute Immediate statement since this feature is not suppoerted at client side and i am doing the coding In my local mchine and running the report loaclly.......???
Another way to use dynamic sql is by using dbms_sql package.
Using dbms_sql to run a sql will give me a normal cursor as an output.
Since in report builder pl/sql only ref cursor is allowed as a return type from a function........the problem i m facing is conversion of the cursor to ref cursor......
in oracle 11g we have a built in function in dbms_sql package that can be used for the conversion....
i m using oracle 10 g where the above mentioned feature is not available............
Please give some way to resolve this issue............!!!!!!!!!!!!
Thanks in Advance.....!!!!!!!
AbhishantYou may use some stored procedures that will take full advantage of dynamic SQL. Make a stored proc that inserts rows in a global temporary table. You will call that stored proc in the afterpform trigger. And you will have the report querry select from the temporary table populated by the stored proc.
I did some things like that.

I am trying to build a report based on Ref Cursor query with dynamic string as given below.
OPEN loc_ref_cur_ugss_pay_car FOR 'SELECT name, email_id, job, remarks FROM employee_desc' ;
On compile I am getting following error.
Encountered the symbol "SELECT....." when expecting one of the following: select.
Can't I use ref cursor with dynamic string?
Thanks & regards,
RakeshIf I will use Select statement without quote then it will be a static query. I want to use the dynamic one which will use different table names depending upon condition. The tables which are to be used here are temparary tables and will be be created through report only.

Report based on Ref Cursor and lock package/table (ORA-04021)
Hi,
I have reports based on Ref Cursor. Report builder and Reports Background Engine make pins for package, which consist of Ref Cursor, and for tables, which is used in package. So I can't grant any privileges on these tables anybody.
For example, after next statement:
GRANT SELECT ON table_name TO user_name
I received the next error:
ORA-04021: timeout occurred while waiting to lock object table_name

I want to be able to use a fuction that will dynamically create a SQL statement and then open a cursor based on that SQL statement and return a ref to that cursor. To achieve that, I am trying to build the sql statement in a varchar2 variable and using that variable to open the ref cursor as in,
open l_stmt for refcurType;
where refcurType is a strong ref cursor. I am unable to do so because I get an error indication that I can not use strong ref cursor type. But, if I can not use a strong ref cursor, I will not be able to use it to build the report based on the ref cursor because Reports 9i requires strong ref cursors to be used. Does that mean I can not use dynamic sql with Reports 9i ref cursors? Else, how I can do that? Any documentation available?Philipp,
Thank you for your reply. My requirement is that, sometimes I need to construct a whole query based on some input, and sometimes not. But the output record set would be same and the layout would be more or less same. I thought ref cursor would be ideal. Ofcourse, I could do this without dynamic SQL by writing the SQL multiple times if needed. But, I think dynamic SQL is a proper candidate for this case. Your suggestion to use lexical variable is indeed a good alternative. In effect, if needed, I could generate an entire SQL statement and place in some place holder (like &stmt) and use it as a static SQL query in my data model. In that case, why would one ever need ref cursor in reports? Is one more efficient over the other? My guess is, in the lexical variable case, part of the processing (like parsing) is done on the app server while in a function based ref cursor, the entire process takes place in the DB server and there is probably a better chance for re-use(?)
Thanks,

Hi..
I'm using a ref cursor query to fetch data for a report and works just fine. However i need to use dynamic sql in the query because the columns used in the where condition and for some calculations may change dynamically according to user input from the form that launches the report..
Ideally the query should look like this:
select
a,b,c
from table
where :x = something
and :y = something
and (abs(:x/:y........)
The user should be able to switch between :x and :y
Is there a way to embed dynamic sql in a ref cursor query in Reports 6i?
Reports 6i
Forms 6i
Windows 2000 PROHello Nicola,
You can parameterize your ref cursor by putting the query's select statement in a procedure/function (defined in your report, or in the database), and populating it based on arguments accepted by the procedure.
For example, the following procedure accepts a strongly typed ref cursor and populates it with emp table data based on the value of the 'mydept' input parameter:
Procedure emp_refcursor(emp_data IN OUT emp_rc, mydept number) as
Begin
-- Open emp_data for select all columns from emp where deptno = mydept;
Open emp_data for select * from emp where deptno = mydept;
End;
This procedure/function can then be called from the ref cursor query program unit defined in your report's data model, to return the filled ref cursor to Reports.
Thanks,

Cursors are not closed when using Ref Cursor Query in a report ORA-01000
Dear Experts
Oracel database 11g,
developer suite 10.1.2.0.2,
application server 10.1.2.0.2,
Windows xp platform
For a long time, I'm hitting ORA-01000
I have a 2 group report (master and detail) using Ref Cusor query, when this report is run, I found that it opens several cursors (should be only one cursor) for the detail query although it should not, I found that the number of these cursors is equal to the number of master records.
Moreover, after the report is finished, these cursors are not closed, and they are increasing cumulatively each time I run the report, and finally the maximum number of open cursors is exceeded, and thus I get ORA-01000.
I increased the open cursors parameter for the database to an unbeleivable value 30000, but of course it will be exceeded during the session because the cursors are increasing cumulatively.
I Found that this problem is solved when using only one master Ref Cursor Query and create a breake group, the problem is solved also if we use SQL Query instead of Ref Query for the master and detail queries, but for some considerations, I should not use neither breake group nor SQL Query, I have to use REF Cursor queries.
Is this an oracle bug , and how can I overcome ?
Thanks

Report using ref cursor or dynamic Sql
Hi,
I never create a report using a ref cursor or a dynamic sql. Could any one help me to solve the below issue.
I have 2 tables.
1. Student_Record
2. Student_csv_help
Student_Record the main table where the data is stored.
Student_csv_help will contain the all the column names of the Student_record.
CREATE TABLE Student_CSV_HELP
ENTRY_ID NUMBER,
RAW_NAME VARCHAR2(40 BYTE),
DESC_NAME VARCHAR2(1000 BYTE),
IN_OUTPUT_LIST VARCHAR2(1 BYTE)
SET DEFINE OFF;
Insert into TOA_CSV_HELP
(ENTRY_ID, RAW_NAME, DESC_NAME, IN_OUTPUT_LIST)
Values
(1, 'S_ID', 'Student ID', 'Y');
Insert into TOA_CSV_HELP
(ENTRY_ID, RAW_NAME, DESC_NAME, IN_OUTPUT_LIST)
Values
(2, 'S_Name', 'Student Name', 'Y');
Insert into TOA_CSV_HELP
(ENTRY_ID, RAW_NAME, DESC_NAME, IN_OUTPUT_LIST)
Values
(3, 'S_Join_date', 'Joining Date', 'Y');
Insert into TOA_CSV_HELP
(ENTRY_ID, RAW_NAME, DESC_NAME, IN_OUTPUT_LIST)
Values
(4, 'S_Address', 'Address', 'Y');
Insert into TOA_CSV_HELP
(ENTRY_ID, RAW_NAME, DESC_NAME, IN_OUTPUT_LIST)
Values
(5, 'S_Fee', 'Tution Fee', 'N');
commit;
CREATE TABLE Student_record
S_ID NUMBER,
S_Name VARCHAR2(100 BYTE),
S_Join_date date,
S_Address VARCHAR2(360 BYTE),
S_Fee Number
Insert into Student_record
(S_ID, S_Name, S_Join_date, S_Address,S_Fee)
Values
(101, 'john', TO_DATE('12/17/2009 08:00:00', 'MM/DD/YYYY HH24:MI:SS'), 'CA-94777', 2000);
Insert into Student_record
(S_ID, S_Name, S_Join_date, S_Address,S_Fee)
Values
(102, 'arif', TO_DATE('12/18/2009 08:00:00', 'MM/DD/YYYY HH24:MI:SS'), 'CA-94444', 3000);
Insert into Student_record

Commit;
Now my requirement is:
I have a form with Student_record data block. When i Click on print Button on this form. It will open another window which has Student_CSV_HELP.DESC_NAME and a check box before this.
The window look like as below:
check_box DESC_NAME+
X S_ID+
-- S_Name+
X S_Join_date+
X S_Address+
-- S_Fee+
X means check box checked.+
-- means check box Unchecked.+
After i selected these check boxes i will send 2 parameters to the report server
1. a string parameter to the report server which has the value 'S_ID,S_Join_date,S_Address' (p_column_name := 'S_ID,S_Join_date,S_Address');
2. the s_id value from the student_record block (p_S_id := '101');
Now my requirement is when i click on run. I need a report like as below:
Student ID : 101+
Joining Date : 12/17/2009 08:00:00+
Address : CA-94777+
This is nothing but the ref cursor should run like as below:
Select S_id from student_record block S_id = :p_S_id;
Select S_Join_date from student_record block S_id = :p_S_id;
Select S_Address from student_record block S_id = :p_S_id;
So, according to my understanding i have to select the columns at the run time. I dont have much knowledge in creating reports using ref cursor or dynamic sql.
So please help me to solve this issue.
Thanks in advance.Plain sql should satisfy your need. Try ....
Select S_id, S_Join_date, S_Address
from student_record
where S_id = :p_S_id -
Dynamic Ref Cursor report in 6i
Hello,
I apologise that this question is so similar to many in this forum, but I haven't found a solution to my problem yet.
I've created a ref cursor query because I need to include a variable p_orgs in my WHERE clause, like so:
where e.org_id in ('||p_orgs||')
I've constructed the report as mentioned on this page:
www.dulcian.com
FAQs - SQL & PL/SQL FAQs - FAQ ID# 5:
"How can you use 'dynamic' ref cursors in Oracle Reports 3.0 / 6i?"
(Thanks to Zlatko Sirotic for the information).
I get a compile error when compiling the package body that holds my ref cursor open statement:
Error 103 Encountered the symbol ''select'' when expecting one of the following:
Select
Is there any way around this problem?
If I was to upgrade to Reports 9i would it work?
Many thanks,
HazelHello,
Just a remark : you don't need to use a Ref Cursor if you just want to use a "dynamic where clause".
You can use a lexical reference :
You can find examples at :
http://www.oracle.com/webapps/online-help/reports/10.1.2/topics/htmlhelp_rwbuild_hs/rwwhthow/whatare/dmobj/sq_a_lexical_references.htm
(This page is about Reports 10.1.2 but Lexical references are identical in Reports 6i and Reports 10.1.2)

How to write REF-CURSOR Query in Oracle Reports
Hello Guys!!
I have a form in which you can select regions/divisions/locations etc by the use of check boxes. And the selected values will be inserted into a table, and based on the selected values of the table the report is run.
The issue I have is with the query inside the Oracle reports(attached to this file).
The query works fine until the last two EXISTS conditions.
IF a region exists In the table report_param then it works fine but if there are no divisions in it , then the query returns no values, which is not correct.
Someone has advised me to use a ref-cursor query inside reports tool, which I am not aware off. So, anykind of suggestions or advises are welcome. Please let me know about it as it is very urgent issue for me. Anykind of help would be greatly
appreciated.
Thanks,
Vishal

I need your help to create a report using Ref-Cursor. please see the below thread
Report using ref cursor or dynamic Sql -
Reports 3.0, Ref Cursor from stored procedure
I have a problem trying to use Ref Cursor as datasource (i.e.
Ref Cursor Query) in Reports 3.0
I have created a stored package with a function which returns
Ref Cursor.
That function just opens the cursor and returns it to the
calling module.
Reports recognizes returned cursor - it creates a group for that
query, with all columns, than I built
a layout model - everything is OK on that stage.
During the execution of that report (from previewer or using
Reports Runtime) I got an error message like that:
REP-0065 Virtual Memory System Error
REP-0200 Cannot allocate enough memory cavaa22
Error's description does not correspond the reality :) - there
is enough virtual & physical memory according to
Task Manager information.
So, that does not work when this package is stored one.
When I create the package on the client side - in Reports -
everything works just fine.
Cursor is opened with a very simple query, selecting records
from the very simple table having only one record.
There is no code written which closes that cursor or fetches the
records.
Client platform: WinNT 4.0 SP3
Oracle Reports: 3.0.5.8.0
Oracle Server: Oracle8 8.0.5.0.0 (and I tried also on Oracle7
7.3.4.3.0)
Thanx.
nullSara,
GTT (Global Temporary Tables) in Oracle work a different way compared to SQL Server and Informix. There you can create temporary tables on the fly and drop them on the fly.
Here you should (note, you don't have to, but, best practice says that you should) create the table using the syntax...
create global temporary table.....
Once you create it, even though it looks like persistent table, it's not. It will have it's own individual data PER SESSION . You have two types of GTTs:
ON COMMIT PRESERVE ROWS and ON COMMIT DELETE ROWS (they work in slightly different way).
