REF CURSOR in PL/SQL BLOCK

I am trying to return a ref cursor from a function in a package. I am trying to execute this through SQL Plus and cannot seem to get the code correct this is what I have. Please help. How do I display the output? I tried a CURSOR FOR loop, but got syntactical error saying it was being used inproperly.
DECLARE
     v_rec      adp_vsp.grc_vsp;
     v_fname ps_personal_data.first_name%TYPE;
     v_lname ps_personal_data.last_name%TYPE;
BEGIN
     v_fname := 'John';
     v_lname := 'Barr';
     v_rec := adp_vsp.f_get_vsp(v_fname,v_lname);
END;

If you want to do it manually, you need to loop through the cursor and fetch the results:
sql>create or replace procedure p_show_emps(p_rc out sys_refcursor)
2 is
3 begin
4    open p_rc for select empno, ename from emp where rownum <= 5;
5 end;
6 /
Procedure created.
sql>declare
2    v_rc     sys_refcursor;
3    v_empno emp.empno%type;
4    v_ename emp.ename%type;
5 begin
6    p_show_emps(v_rc);
7    loop
8      fetch v_rc into v_empno, v_ename;
9      exit when v_rc%notfound;
10      dbms_output.put_line( v_empno || ', ' || v_ename );
11    end loop;
12    close v_rc;
13 end;

How to print a HTML file in browser look using DocPrintJob

Hello guys,
Does anyone know how to print HTML output/file into browser look?
I'm using DocPrintJob and the DocFlavor set to DocFlavor.INPUT_STREAM.AUTOSENSE.
posted below is my code :
public class BasicPrint {
    public static void main(String[] args) {
        try {
            // Open the image file
            String testData = "C:/new_page_1.html";
            InputStream is = new BufferedInputStream(new FileInputStream(testData));
            DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
            // Find the default service
            PrintService service = PrintServiceLookup.lookupDefaultPrintService();
            System.out.println(service);
            // Create the print job
            DocPrintJob job = service.createPrintJob();
            Doc doc= new SimpleDoc(is, flavor, null);
            // Monitor print job events; for the implementation of PrintJobWatcher,
            // see e702 Determining When a Print Job Has Finished
            PrintJobWatcher pjDone = new PrintJobWatcher(job);
            // Print it
            job.print(doc, null);
            // Wait for the print job to be done
            pjDone.waitForDone();
            // It is now safe to close the input stream
            is.close();
        } catch (PrintException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
    static class PrintJobWatcher {
        // true iff it is safe to close the print job's input stream
        boolean done = false;
        PrintJobWatcher(DocPrintJob job) {
            // Add a listener to the print job
            job.addPrintJobListener(new PrintJobAdapter() {
                public void printJobCanceled(PrintJobEvent pje) {
                    allDone();
                public void printJobCompleted(PrintJobEvent pje) {
                    allDone();
                public void printJobFailed(PrintJobEvent pje) {
                    allDone();
                public void printJobNoMoreEvents(PrintJobEvent pje) {
                    allDone();
                void allDone() {
                    synchronized (PrintJobWatcher.this) {
                        done = true;
                        PrintJobWatcher.this.notify();
        public synchronized void waitForDone() {
            try {

                    wait();
            } catch (InterruptedException e) {
}the printed ouput for this code will be look like this
<html>
<body>
<div style="page-break-after:'always';
            background-color:#EEEEEE;
            width:400;
            height:70">
     testPrint</div>
ABCDEFGHIJK<p>
</p>
</body>
</html>however, the output that i want is the HTML in browser look not HTML code itself.
i've tried to change the DocFlavor into any TEXT_HTML type but it gives error:
sun.print.PrintJobFlavorException: invalid flavor if you guys has any idea or solution, can you share with me... already search in Google but still not found any solution
Thanks in advanced.

How to print a pdf file from Labview

Hi,
Does anyone know how to print a pdf file form Labview. I need to be able to point on the pdf file and to print it.
Activex examples doesnt seem to be working it always displays an error, on every PC that I tryed to run it.
{"code 3005" ,,,"Automation Open: Object specified is not creatable in Display PDF in Dialog.vi"}.
Thank you for your help.
Regards,
Jenia.

You can use the "System Exec.vi". The command line should have the following structure:
"<Path to AcroRd32.exe>" /t "<Path to document>" "Printer name"
For example"
"C:\Program Files\Adobe\Acrobat 5.0\Reader\AcroRd32.exe" /t "C:\myreport.pdf" "Tektronix Phaser 300i"

How to print a pdf file of compounds A3 and A4 with adobe mac

how to print a pdf file of compounds A3 and A4 with adobe mac, windows with the option I choose paper source by PDF page size mac but I can not find it. how to get it thank you

I think if you use the start-command, the execution is asynchronously and you won't get the correct process-id. Try to execute Acorbat directly without the cmd /c start in front of it.

How to print a PDF file that was display in my page...

Hi !. My doubt would be the following one... I would like to know how to print a pdf file that was displayed in my page ?... I mean the PDF file not the page...
The PDF would be in this url:
http://iprodesa.lasegunda.com.ar:8090/datos/pdf/830.pdf
How could I implement this ?...

This first question which comes to mind is how do you display the pdf file in the browser?
For this the browser uses a plug in (e.g. adobe reader) which already has the ability to print the pdf file. Depending on the version of your plug in, printing is started differently.

Ps: which jdev version do you use?

How to handle the ref cursor which is returning "no rows"

I have written a function which is returning the REF CURSOR. But in one situation the REF CURSOR returns "no rows selected". To handle this situation an exception is raised "when no data found". But i dont know in this situation how should NULL cursor be returned through this function. Since I want to call this function in another procedure so something should be returned through this function by means of ref cursor. But since i am not able to handle this "no rows selected" situation i am not able move further.
Thanks in advance........

I agree.
You would simply process the returned ref cursor irrespective of any rows actually returned in the cursor or not. You would be able to do at least one FETCH from the cursor (even if it does not actually contain any rows) and then determine the %NOTFOUND status to do the rest of the processing.

[Solved] 27.8.4 How to Create a VO on a REF CURSOR - Missing first row

Searching the forum I found: BC4J - Get one less row from view object.
Dive into BC4J related --REF CURSOR (Resultset)
The first message did not have any answers, and the second had a follow up question - still no answers though - and I thought I would try a different title.
(This is off topic, but it would be a great help if the search results also displayed the number of replys in the thread. That way, I wouldn't have to view the messages that don't have responses.)
(This will be deployed on a server that has the ADF for JDeveloper 10.1.2 installed, so using that version of JDeveloper to develop the app.)
Okay, back to the problem ==>
I created a VO from a ref cursor, using the manual as a guide. When I run a page that displays a read only table of the view object, I am missing the first row. (Always the first row!) I don't have any order set, and if I call the ref cursor in a Java program for testing, I see all rows and the count is correct.
One other point, when I call the page, I get the following validation error:
Validation Error
You must correct the following error(s) before proceeding:
* JBO-29000: Unexpected exception caught: java.lang.ClassCastException, msg=null
* null
I still see the table, it is just missing the first row of data.
In my form I have first, previous set, next set , and last
navigation buttons. If I press last then first, the error goes away. I still don't see the missing row though.
Any guidance would be appreciated! I can post my code, but it is pretty much the same code in the AdvancedViewObjectExamples.zip in the ViewObjectOnRefCursor example. I just substituted my two package calls (getRefCursor and getRefCursorCount).
Thanks, Ken

Went back to a backup copy of the source. Fixed the error. Now I'm back to just not being able to see the first row of data.
Additional Note: I had removed fields in the display. Once I truncated the ps_txn table in the schema defined by the model, the data would display (Still without the first record.)
Are there any examples that are more in depth than the few pages in the developer guide?

How to put a collection into a Ref Cursor?

Hi,
I am trying to create a procedure (inside a package) which fills a collection and I need to fill a ref cursor (out parameter) with this collection. I can fill the collection but I how can I fill the ref cursor? I am receiving the message "PL/SQL: ORA-00902: invalid datatype" (Highlighted below as comments)
I have a limitation: I am not allowed to create any kind of objects at the database schema level, so I have to create them inside the package. I'm writting it with SQL Tools 1.4, I'm also not allowed to do this in SQL+.
This is the code of the package. The cursors' selects were simplified just because they are not the problem, but their structure is like follows below.

Ref cursors and dynamic sql..

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,
Murali.

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
(S_ID, S_Name, S_Join_date, S_Address,S_Fee)
Values
(103, 'raj', TO_DATE('12/19/2009 08:00:00', 'MM/DD/YYYY HH24:MI:SS'), 'CA-94555', 2500);
Insert into Student_record
(S_ID, S_Name, S_Join_date, S_Address,S_Fee)
Values
(104, 'singh', TO_DATE('12/20/2009 08:00:00', 'MM/DD/YYYY HH24:MI:SS'), 'CA-94666', 2000);
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

Ref cursor and dynamic sql

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 PRO

Hello 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,
The Oracle Reports Team.
