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.

Sara,
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).
Look up GTTs here:

Returning SQL cursor from Stored Procedure

Hi,
I have a query regarding returning sql cursor from stored procedure to java in oracle 11g.
I want to query some data ex: my query returns A, B, C. Also, now I want to query some other data ex: D, E, F. Now I want to return this data as an sql cursor as a single row . Example: A,B,C,D,E,F. Is it possible to return/create a cursor in stored procedure?
assume both query returns equal number of rows.. however both are not related to each other..

assume both query returns equal number of rows.. however both are not related to each other..It sounds like what you need is a ref cursor.
First thing to remember though is that cursors do not hold any data (see: {thread:id=886365})
In it's simplest form you would be creating a procedure along these lines...

Populate report page based on results from stored procedure

Is it possible to populate a report page in APEX based on the results from a stored procedure? If so, how do I do it? Do I write a stored procedure with a ref cursor as out parameter?

I would use a stored procedure to return the values for a form but not for a report. For a
report, I would use a pipelined function. See an example here:

OCI8: returning cursors from stored procedures

The short version of my question is:
In OCI8, how do open a cursor from the database stored procedure, return it to my C++ program and fetch from it, given that in OCI8 cursors and cursor functions are becoming obsoleted?
The long version of the same question is:
I am converting my C++ code from the Oracle 7.3 OCI driver to the Oracle8 OCI driver. One thing I did very frequently in Oracle 7.3 OCI code is open a multi-row select cursor within a stored procedure and return that cursor to my program. In the program, I would then do the fetching with the returned cursor. This was very useful, as it allows me to change the queries in the stored procedure (for example, to append information to certain columns or make some data in all uppercase) without recompiling the application due to a changed SQL string.
My 7.3 psuedocode is as follows:
stored procedure def:
TYPE refCurTyp IS REF CURSOR;
FUNCTION LoadEmployeeData RETURN refCurTyp;
stored procedure body:
FUNCTION LoadEmployeeData RETURN refCurTyp IS
aCur refCurTyp;
BEGIN
OPEN aCur FOR
SELECT emp_id, emp_name
FROM employee_table
ORDER BY emp_name;
return aCur;
END;
OCI code: // all functions are simplified, not actual parameter listing
// declare main cursor variable #1 and return cursor variable #2
Cda_Def m_CDAstmt, m_CDAfunction;
// open both cursors
oopen(m_CDAstmt, ...);
oopen(m_CDAfunction, ...);
// bind cursor variable to cursor #2
oparse(&m_CDAstmt, "BEGIN :CUR := MYPACKAGE.LoadEmployeeData; END;");
obindps(&m_CDAstmt, SQLT_CUR, ":CUR", &m_CDAfunction);
// run cursor #1
oexn(&m_CDAstmt);
// bind variables from cursor #2, and fetch
odefineps(&m_CDAfunction, 1, SQLT_INT, &m_iEmpId);
odefineps(&m_CDAfunction, 2, SQLT_CHAR, &m_pEmpName);
while (!ofen(&m_CDAfunction))
// loop: do something with fetch
// values placed in m_iEmpID and m_pEmpName
This works perfectly, and has really helped to make my code more maintainable. Problem is, in Oracle 8 OCI both cursors and the cursor functions (such as oopen()) are becoming obsoleted. Now it uses statement and environment handles. I know I can still use Cda_Def and cursors--for a while--within OCI8, but I need to know the official up-to-date method of returning a cursor from the database and fetching within my C++ code. Any code fragment, or explanation of what I need to do in OCI8 would be appreciated (perhaps I need to bind to a statement handle instead? But the stored procedure still returns a cursor.)
The Oracle8 OCI has a new SQLT_ type, SQLT_RSET, which the header file defines as "result set type". Unfortunately, it's almost completely undocumented in the official documentation. Am I supposed to use this instead of the obsolete SQLT_CUR?
Thanks,

1) How to use ref cursors in procedure. what is the main use.All SQL in Oracle are parsed as cursors in the Shared Pool. The client code (be that PL/SQL or Visual Basic or Java) gets a handle or reference to this SQL cursor on the server.
Using this handle, the client can fetch rows using the cursor (the cursor is like a program - the executable binary version of the source SQL code).
Clients implement their interfaces with this SQL cursor handle in different ways. PL/SQL alone supports:
- implicit cursor handles
- explicit cursor handles
- DBMS_SQL cursor handles
- reference cursor handles
Why so many? Different tools for different jobs. Each has its pros and cons and each is suited for specific (and different) types of problems.
A ref cursor is special in that PL/SQL can pass this SQL cursor reference handle to an external client to use - like Java.
Why?
The basic concept is that of abstraction. Removing the complexities of SQL and the database design and SQL optimisation from the Java code. Instead, Java calls a PL/SQL proc. This proc creates the SQL cursor, and uses a reference cursor variable to store the SQL cursor handle. It can then pass this to Java. This means that the entire SQL is encapsulated in the PL/SQL proc. We can now modify it, optimise it, support data models changes in the database via the PL/SQL proc... all without even having to recompile the Java code that makes the call and consumes the ref cursor the PL/SQL proc gives it.
2) How to close ref cursors in procedure.If it is need.Yes. A very important factor - well spotted.
As PL/SQL can pass ref cursors to external clients. it does not automatically close these cursors. It does not know when the client has consumed the cursor. It will only close it when the cursor is still open, when the Oracle server session is terminated.
So it is important that the client (Java in this case) closes the cursor when done. If not, the cursor will remain open, will continue to occupy server resources... and if the client opens more and more of these cursors, the server process will run out of resources.
Cursor leakage by Java developers are common - and can simply be avoided by closing the cursor once the Java code has consumed it.
3) How to use exceptions in procedures for ref cursors.No. Why? Why would you want to deal with the exception in a PL/SQL proc? The Java code wants to open that cursor. It knows why. It knows what to do when that cursor fails or is empty. It interacts with the user. How is the PL./SQL proc, whose only function is to construct the SQL and pass the cursor handle to Java, to know any of this?
Exceptions in this regard should typically be handled in Java. Not in PL/SQL.
Of course, if that PL/SQL proc has parameters, it also needs to validate these and it needs to raise application exceptions to inform the Java caller when these parameters are invalid.
But actually catching exception in this case... does not make much sense. As what can the PL/SQL do about the error when it is a "server" and Java is the "client"?
It is like saying that the Oracle Server should handle all exceptions when TOAD is used and incorrect SQL is passed to it. How does it make sense for Oracle to process SQL errors and the TOAD client not getting any results from a wrong SQL and not knowing that there was even an error with that SQL?

How to get an UPDATABLE REF CURSOR from the STORED PROCEDURE

using C# with
ORACLE OLE DB version: 9.0.0.1
ADO version: 2.7
I returns a REF CURSOR from a stored procedure seems like:
type TCursor is ref cursor;
procedure test_out_cursor(p_Dummy in varchar, p_Cur out TCursor) is
begin
open p_Cur for select * from DUAL;
end;
I create an ADO Command object and set
cmd.Properties["IRowsetChange"].Value = true;
cmd.Properties["Updatability"].Value = 7;
cmd.Properties["PLSQLRSet"].Value = 1;
cmd.CommandText = "{CALL OXSYS.TEST.TEST_OUT_CURSOR(?)}";
and I use a Recordset object to open it:
rs.Open(cmd, Missing.Value,
ADODB.CursorTypeEnum.adOpenStatic,
ADODB.LockTypeEnum.adLockBatchOptimistic,
(int) ADODB.CommandTypeEnum.adCmdText +
(int) ADODB.ExecuteOptionEnum.adOptionUnspecified);
The rs can be opened but can NOT be updated!
I saved the recordset into a XML file and there's no
rs:baseschema/rs:basetable/rs:basecolumn
attributes for "s:AttributeType" element.
Any one have idea about this?
thanks very much

It is not possible through ADO/OLEDB.
Try ODP.NET currently in Beta, it is possible to update DataSet created with refcursors. You need to specify your custom SQL or SP to send update/insert/delete.
As I remember there is a sample with ODP.NET Beta 1 just doing this.

How to generate a report from stored procedure

I would like to generate a report from stored procedure.
I used to work on sql server. this can be done as easy as put a select statement at the end of stored procedure.
The resule can be displayed on the development IDE, like sql developer or consume by Java JDBC client.
is there equivalent way to do this in Oracle stored procedure?

Hi,
What type of report you are looking..for.. ??
As you said that "I used to work on sql server. this can be done as easy as put a select statement at the end of stored procedure. "
When you execute it will return the result set and you will display directly on the FrontEnd.. Is my Understanding is correct Up to here.
See, In oracle you have call some custom stored procedures as you did in SQL Sever, but you have return the Results Sets, with help of Out put paramter, Either Cursors or Varrays..
or Else you can generate the Html reports based on your requirement, HTML can be used in the stored procedures of Oracle which will generate for your, you need to code it.
I could not able get the relevant link for your reference.
I will get back to you on this.

We are trying from Pro*Cobol on MVS (which has db link pointing to AIX thru db link) and get a 00993 error, which seems to say this is not possible.
Before I give up, thought I would check with the experts....
Thanks in advance.

You can't return Java objects as stored procedure or query results.

Can any body help me ..
The output variable of db adapter is refcursor from stored procedure. in ref cursor i will get xml from a clob variable. how to use it in bpel...can an body help me how to do it....

APEX is based on Oracle Database. Whatever you can do with PL/SQL, the same can be done with APEX also. APEX stores the application definition in the form of metadata.
So if you put all your logic and code in packages, procedures or functions then it will be really good compact and modular approach.
Bottom line is that you can do all of those.
Check the documentation at

How to out Dynamic ref cursor from Procedure to Forms

Hi
I am trying to out Dynamic ref cursor from Procedure to Forms, But I am unable to do so. however cursor return the value within procedure but I am failed to capture the same in Forms
Pl advice suggestion if any, Here I am attaching full procedure for reference
CREATE PACKAGE winepkg
IS
TYPE wine IS RECORD ( mynumber number);
/* Define the REF CURSOR type. */
TYPE wine_type IS REF CURSOR RETURN wine;
END winepkg;
CREATE procedure find_wine

c1 out winepkg.wine_type) as
vsql varchar2(1000);
cur sys_refcursor;
x number;
BEGIN
vsql:='select bo_id from bo_details where bo_details.bo_id = '||col1_in ;
open cur for vsql;
c1:=cur;
--fetch c1 into x;
--dbms_output.put_line(x);
END find_wine;
In front end forms
Declare
TYPE F is REF CURSOR;
CUR_F F;
rec number;
Begin
break;
find_wine( 1601480000011078,cur_f ) ;
Loop
fetch cur_f into rec ;
Message(rec ) ;pause;
exit when cur_f%notfound ;
End loop ;
exception
when others then
Message(sqlerrm) ;pause;
End ;

yo can use
declare
c_cursor EXEC_SQL.CursType;
v_stmt varchar2(2000) = 'select a, b, c from mytab where cond1'; -- you can create this value dynamically
begin
c_cursor := Exec_SQL.Open_cursor;
EXEC_SQL.PARSE(c_articulos, v_stmt);
EXEC_SQL.DEFINE_COLUMN(c_articulos,1, v_colchar1, 30);
EXEC_SQL.DEFINE_COLUMN(c_articulos,2, v_colchar2, 15);
EXEC_SQL.DEFINE_COLUMN(c_articulos,3, v_colchar3, 30);
v_exec := EXEC_SQL.EXECUTE(c_cursor);
WHILE EXEC_SQL.FETCH_ROWS(c_cursor) > 0 LOOP

Returning rowcount and resultset from stored procedure

Hello,
In SQL Server you can return multiple resultsets from stored procedure by simple SELECT statement. But in Oracle, you have to use SYS_REFCURSOR.
Sample code:
CREATE OR REPLACE PROCEDURE sp_resultset_test IS
t_recordset OUT SYS_REFCURSOR
BEGIN
OPEN t_recordset FOR
SELECT * FROM EMPLOYEE;
END sp_resultset_test;
Is there any other way in Oracle 10 or 11 ?
Thank You.

What is the requirement? Oracle is far more flexible than SQL-Server... with numerous features that do not exist in SQL-Server. (Fact)
One of the biggest mistakes you can make is to treat Oracle like SQL-Server... trying to match feature A1 in SQL-Server to feature B3 in Oracle.
Does not work that way.. rather then stick to SQL-Server as SQL-Server does SQL-Server specific features far better than Oracle.
So instead of trying to map what a T-SQL stored proc to do to an Oracle ref cursor (even to the extent of using that very silly sp_ prefix to name the proc), tell us the problem and requirements... That way we can tell you what Oracle features and options are best used to solve that problem - instead of competing in some unknown feature comparison event with SQL-Server.

Populate a REF CURSOR from regular cursor...

Hi all,
I apologize if the answer to this is somewhere...I've been looking on the web for sometime and can't find an answer to the following problem. I have a Significant Events database that contains network based issues and problems. As problems are detected on the network an SE is issued and published. As the SE records are updated, NEW records are entered into the table and "linked" back to the original. Each update results in a new row. Thus, an SE with two updates would have a total of 3 lines. When the SE gets closed (set the column CLOSED to SYSDATE), only the "original" SE is closed, any updates are left open...aka, the CLOSED column is left null.
That said, I need a way to get the original and/or latest updated SE rows from the table. Thus, I am trying to use a PL/SQL package. The PL/SQL "must" return a REF CURSOR as the results are being passed to a client process.
My initial approach was within a PL/SQL procedure, I have an SQL statement that returns the SE originals. Once in that cursor I need to do the following:
- Attempt to fetch any linked SE rows.
- if no rows then
- add the original to the REF CURSOR.
- else
- find latest SE update
- add latest SE update to REF CURSOR.
- end if
My Question is : How do I manually "add" a row to a REF CURSOR?
If this is not possible, is there a way to populate a REF CURSOR from maybe another construct like:
TYPE ian_se_record is RECORD (
se_id number
,linked_se_id number
,submitted date
,updated date
,closed date
,segroup varchar2(150)
,incident_start_time varchar2(150)
,business_units_affected varchar2(150)
,officenum varchar2(1500)
,sedetails varchar2(4000)
TYPE ian_se_table is table of ian_se_record index by binary_integer;
With the above construct I could:
- Fill ian_se_table with the process described above.
- And finally select off ian_se_table into the REF CURSOR?
Any help would be greatly appreciated,
adym

Hi michaels,
I've put your solution in place, but can't seem to get it to run. The two types were moved out of the package and into real types as you said. Here's the function, for brevity, I've remove some of the less important code:
function ian_se_fetch return sys_refcursor
is
    p_csr_events            sys_refcursor;
    cursor csr_items is
        select
             se_id
    ...removed for brevity...
    /* END : csr_items */
    ian_se_row     ian_se_record;
    ian_se_tbl     ian_se_table;
    l_lng_index    number;
    l_lng_linked   number;
    l_lng_id       number;
begin
     * OPEN : Open the main cursor of originals...
    for the_item in csr_items loop
         * CHECK : Check for any updates to the original...
        l_lng_linked := 0;
        select count(*)
        into l_lng_linked
        from sig_se_t src
        where src.linked_se_id = the_item.se_id;
        l_lng_id := 0;    /* reset the se-id    */
        /* SE original...no linked records yet.    */
        if ( l_lng_linked = 0 ) then
            l_lng_id := the_item.se_id;
        /* SE updates...one or more updates are present.    */
        else
            begin
                select
                     se_id
                into l_lng_id
                from sig_se_t src
                where src.linked_se_id = the_item.se_id
                  and rownum = 1
                order by updated desc; /* latest update    */
            exception
                when too_many_rows then
                    l_lng_id := the_item.se_id;
                when others then
                    l_lng_id := 0;
            end;
        end if;
        if ( l_lng_id != 0 ) then
            select
                 se_id
                ,linked_se_id
                ,submitted

                              )                           impact
                ,sedetails
            into ian_se_row.se_id

            ian_se_tbl(l_lng_index).closed                  := ian_se_row.closed;
            ian_se_tbl(l_lng_index).segroup                 := ian_se_row.segroup;
            ian_se_tbl(l_lng_index).incident_start_time     := ian_se_row.incident_start_time;
            ian_se_tbl(l_lng_index).business_units_affected := ian_se_row.business_units_affected;
            ian_se_tbl(l_lng_index).officenum               := ian_se_row.officenum;
            ian_se_tbl(l_lng_index).sedetails               := ian_se_row.sedetails;
        end if;
    end loop;
     * REF CURSOR : Open the ref cursor on the dataset...
    if ( nvl(ian_se_tbl.last,0) = 0 ) then
        p_csr_events := null;
    else
        open p_csr_events for
        select *
        from table (cast ( ian_se_tbl as ian_se_table ));
    end if;
    return p_csr_events;
end;Here's the test. I keep getting the same error ORA-06530:
SQL> variable v refcursor;
SQL> exec :v:=pkg_ian.ian_se_fetch;
BEGIN :v:=pkg_ian.ian_se_fetch; END;
ERROR at line 1:

ORA-06512: at line 1
SQL> print v
ERROR:
ORA-24338: statement handle not executedOther things I tried:
- The ian_se_fetch() function was a procedure using an in out parameter...same error.
- Wrote a small anonymous block and tried to LOOP/FETCH. Same ORA-06530 error.
P.S. Line 131 of pkg_ian is the SELECT ... INTO ian_se_row.se_id, ...
Any help would be greatly appreciated,
