Returning Multiple Cursors

This is a pretty straightforward question but I'm a bit of a newbie. I'm interested in returning a bunch of data from about 10 or so tables so I can dynamically populate some dropdown lists, etc.
I'd like to create a stored procudure to do this. What is best practice?
Should I make one stored procudure that has 10 Out Ref Cursor Paramaters or break this up into multiple Stored Procedures? Is using the Out Ref Cursors the best way of doing this?
Any help would be much appreciated, Thanks.

Having one stored procedure returning 10 REF Cursors would give you much better performance then having 10 stored procedures returning one REF Cursor each.

Return multiple cursors

I need help in figuring out the best solution for returning data through a package which will contain repeating data from multiple tables. For example
I have two tables one and two
one(position,name) and contains
sales, david
sales, jane
marketing, jon
two (name, product_id) contains
david, 45
david, 68
david, 75
jane, 1
the user will input position and i need to return a cursor that will contain all the values in tables one and two where names equal each other. So if a person enters in sales i would need to return
sales, david, 45
68
75
sales, jane 1
without repeating position and name over and over.

You may use two ref cursors
CREATE OR REPLACE PROCEDURE test_ps (
   in_id         NUMBER,
   cur1    OUT   sys_refcursor,
   cur2    OUT   sys_refcursor
AS
BEGIN
   OPEN cur1 FOR
      SELECT 1
        FROM DUAL;
   OPEN cur2 FOR
      SELECT 2
        FROM DUAL;
END;

Return multiple cursors from one procedure

Hi,
I have a stored procedure that is suposed to return multiple records. I know that for each table that I return I have to add a param to the stored procedure, param with ref cursor type.
I do not know exactly how many tables I have to return, it depends on data from some tables.
Is it possible to return an unknown number of tables? like an array or something ...
Please help

In order to keep it transparent to the developer, I have to translate exactly the stored procedures from SQL Server to Oracle.Well "exactly" is not something that you are going to achieve. You're talking about two disperate languages. That's like saying you want to translate French to English, but it must stay French.
You obviously want to mimick the existing functionality, but in some cases you're just going to have to bite the bullet and accept that you won't be able to do it totally transparently. In this case, the developers are going to have to make some changes at their end of things too.
To translate the procedures from T-SQL to Oracle was
the easiest and most convenient option to the
developers, so they will not have to write different
code for Oracle and SQL.But they will. Anyone who evaluated the project and determined that the developers wouldn't need to do anything when moving from one platform to another should be sacked for incompetence.

Sending an Email with a cursor that returns multiple fields.

I was investigating about sending emails from apex, and I'd like to know if you can help me, I need to send an Email report with multiple fields, I m using this code :
DECLARE
CURSOR c1 is
select id,gk,creation_date,sr_count,issue_notes,sr_impacted,oldest_creation_date
from gk_report where id = (select max(id) from gk_report);
reg c1%ROWTYPE;
begin
IF (c1%ISOPEN = TRUE) THEN
CLOSE c1;
END IF;
OPEN c1;
FETCH c1 INTO reg;
CLOSE c1;
APEX_MAIL.send(
p_to => '[email protected]',
p_from => '[email protected]',
p_body => 'Hourly GK Log',
p_body_html =>
'GK: '||to_char(reg.gk)||'<br>
CREATION DATE: '||to_char(reg.CREATION_DATE,'DD-MON-YYYY HH24:MI:SS')||'<br>
SR COUNT: '||to_char(reg.SR_COUNT)||'<br>

p_cc => NULL,
p_bcc => NULL ,
p_replyto => NULL
end;
In this code there is a cursor that returns just one field, But what about if the cursor returns multiple fields, How can I insert a Loop into this code.?
Thanks,

The simplest way for plsql procedure to return multiple rows

Hi,
What is the simplest way for plsql procedure to return multiple rows (records). There are many combination of ways to do it but I am looking for a solution that is appropriate for plsql beginners. Many solutions use cursors, cursor variables, collections and more that kind of things that are complex on the face of it. Is it somehow possible to achieve the same with less effort?
Sample query would be: SELECT * FROM EMPLOYEES;
I want to use returned rows in APEX to compose APEX SQL(in that context plsql) report.
It is enough to use just SELECT * FROM EMPLOYEES query in APEX but I want to use plsql procedure for that.
Thank you!

Hi,
It depends :-).
With +...that is appropriate for plsql beginners...+ in mind... it still depends!
The list of techniques (ref cursors, cursor variables, collections, arrays, using explict SQL) you have referenced in your post can be made to work. but...
+Is it somehow possible to achieve the same with less effort?+ Less effort : That needs to be defined (measured). Especially in the context of pl/sql beginners (who is a beginner?) .
What is the level of "programming experience" ?
What is the level of understanding of "Relational Result set" as processible in Oracle?
If you are looking for
Process_the_set_of rows_in APEX () kind of capabilitywhich "abstracts/hides" relation database from developers when working on relation database, it may not be the best approach (at least strategically). Because I believe it already is abstracted enough.
I find REF CUROSOR most effective for such use, when the "begginer" has basic understanding of processing SQL result set .
So in a nut shell, the techniques (that you already are familiar with) are the tools available. I am not aware of any alternative tools (in pure Oracle) that will simplify / hide basics from develpers.

Return multiple values from a function to a SELECT statement

I hope I've provided enough information here. If not, just let me know what I'm missing.
I am creating a view that will combine information from a few tables. Most of it is fairly straightforward, but there are a couple of columns in the view that I need to get by running a function within a package. Even this is fairly straightforward (I have a function named action_date in a package called rp, for instance, which I can use to return the date I need via SELECT rp.action_date(sequence_number).
Here's the issue: I actually need to return several bits of information from the same record (not just action_date, but also action_office, action_value, etc.) - a join of the tables won't work here as I'll explain below. I can, of course, run a separate function for each statement but that is obviously inefficient. Within the confines of the view select statement however, I'm not sure how to return each of the values I need.
For instance, right now, I have:
Table1:
sequence_number NUMBER(10),
name VARCHAR(30),
Table2:
Table1_seq NUMBER(10),
action_seq NUMBER(10),
action_date DATE,
action_office VARCHAR(3),
action_value VARCHAR(60),
I can't simply join Table1 and Table2 because I have to do some processing in order to determine which of the matching returned rows I actually need to select. So the package opens a cursor and processes each row until it finds the one that I need.
The following works but is inefficient since all of the calls to the package will return columns from the same record. I just don't know how to return all the values I need into the SELECT statement.
CREATE VIEW all_this_stuff AS
SELECT sequence_number, name,
rp.action_date(sequence_number) action_date,
rp.action_office(sequence_number) action_office,
rp.action_value(sequence_number) action_value
FROM table1
Is there a way to return multiple values into my SELECT statement or am I going about this all wrong?
Any suggestions?
Thanks so much!

Hi,
What you want is a Top-N Query , which you can do using the analytic ROW_NUMBER function in a sub-query, like this:
WITH     got_rnum     AS
     SELECT     action_seq, action_dt, action_office, action_type, action_value
     ,     ROW_NUMBER () OVER ( ORDER BY action_date
                               ,            action_seq
                         ,            action_serial
                       ) AS rnum
     FROM     table2
     WHERE     action_code     = 'AB'
     AND     action_office     LIKE 'E'     -- Is this right?
SELECT     action_seq, action_dt, action_office, action_type, action_value
FROM     got_rnum
WHERE     rnum     = 1
;As written, this will return (at most) one row.
I suspect you'll really want to get one row for each group , where a group is defined by some value in a table to which you're joining.
In that case, add a PARTITION BY clause to the ROW_NUMBER function.
If you'd post a little sample data (CREATE TABLE and INSERT statements), I could show you exactly how.
Since I don't have your tables, I'll show you using tables in the scott schema.
Here's a view that has data from the scott.dept table and also from scott.emp, but only for the most senior employee in each department (that is, the employee with the earliest hiredate). If there happens to be a tie for the earliest hiredate, then the contender with the lowest empno is chosen.
CREATE OR REPLACE VIEW     senior_emp
AS
WITH     got_rnum     AS
     SELECT     d.deptno
     ,     d.dname
     ,     e.empno
     ,     e.ename
     ,     e.hiredate
     ,     ROW_NUMBER () OVER ( PARTITION BY d.deptno
                               ORDER BY         e.hiredate
                         ,                e.empno
                       ) AS rnum
     FROM     scott.dept     d
     JOIN     scott.emp     e     ON     d.deptno     = e.deptno
SELECT     deptno
,     dname
,     empno
,     ename
,     hiredate
FROM     got_rnum
WHERE     rnum     = 1
SELECT     *
FROM     senior_emp
;Output:
.    DEPTNO DNAME               EMPNO ENAME      HIREDATE
        10 ACCOUNTING           7782 CLARK      09-JUN-81
        20 RESEARCH             7369 SMITH      17-DEC-80
        30 SALES                7499 ALLEN      20-FEB-81
By the way, one of the conditions in the query you posted was
action_office     LIKE 'E'which is equivalent to
action_office     = 'E'(LIKE is always equivalent to = if the string after LIKE doesn't contain any wildcards.)
Did you mean to say that, or did you mean something like this:
action_office     LIKE 'E%'instead?

Return multiple links (href)

Hi,
I am customizing a software application using Stored Procedure and XML to display information on multiple links (a href tag). My scenario is as follows.
I am accepting SP parameters and returning reference cursor for 1 or more records (depending on the condition). I am wondering how I can use multiple link values based on each record unique value (ID etc).
Can I test result of reference cursor using IDE (PL/SQL developer, Oracle sql developer).
My stored procedure works fine without links.
PROCEDURE GetLinkValues (
resultData OUT SYS_REFCURSOR
) AS
BEGIN
OPEN resultData FOR
select
id, name, '<a href GetDetails.dll' a.id || '</a>' as MultipleLinks
from Test
where {Filter Recrods}
END GetLinkValues;
Any help is appreciated.
Thanks
Sam

The calling program must set this flag, not your search-help.
On a select-option field, don't press F4 but the yellow arrow right, the multiple line selection screen is displayed, there you press the "multi-selection" box.

SQL Command returns multiple records, but I see only one record in report

I work with Crystal Reports XI R2 SP3 and Oracle 10g R2 database.
I have an SQL Command that returns multiple records. Command name is "CommDivisionNames" and it returns column "CommDivisionNames.DIVISION_NAME". When I place this field into report details section of the report, I can see all 10 records returned and this is how it should be. I actually need this field to be placed in the report header section, and when I place the field there, then I see only the first record. I set that field as "can grow = true". When I do "browse field data" for this field, I see that all 10 records are there, but only the first one is displayed in report header section.
I thought that I can place SQL Command field anywhere on the report (page header, footer, details) and that it will always show all records that it returns from the database. Can that be done?
My "main part" of the report returns different set of records, and that's what I have in "report details" section. I need this list of divisions to be in the report header section, so user can see that the report was executed for DivA, DivC, DivE.
Thank you,
Milan

sharonamt:
Users select divisions from parameter, but the parameter multi values are division_numbers (1,5,10), not division_names. Division_names are visible in parameter_prompt_window as description, but parameter remembers only numbers and I don't know how I can reuse division_names later in formula.
I do join for division_numbers and make them into one string variable and pass to sub-report, but I think that I can only get these division_names by calling an SQL command or calling stored procedure.
If I try to do join({MySQLcommand.DIVISION_NAME}) I get error message "A string array is required here".
Carl:
I'm playing with cross-tab and I can use it to see all division_names in the report-header section. Since I need them in only one column or only one row, I have to edit cross-tab object and turn all unneeded border lines to white to make them look invisible. So, cross-tab could be a solution for my problem here.
Another option could be to re-write my SQL command. Since I've read here that SQL command could be written in the same way as I would write a stored procedure, then I could use a bit more complex code to get all multiple division names from the database table into a local cursor, and then use do-while loop to concatenate them into one string, and then to return that string as one record (like 'DivA, DivB, DivC'), and then it should not be a problem to display only that one record/string in report header. It is my understanding that Crystal Reports can call stored procedure that works with many cursors/recordsets and CR will use only the last recordset from the stored procedure. Do you think it could be done this way?
Thank you,
Milan

Calling stored procedure and returning multiple resultsets

Hello,
Is it possible to create a procedure that return multiple result sets?
e.g.
procedure GetDataFromTables() is
begin
select * from table_one;
select * from table_two;
end GetDataFromTables;
And I want to call this procedure that returns multiple resultsets (one for table_one and another for table_two)
I have referred to the OCCI sample occiproc.cpp, but I am not sure how to handle multiple resultsets.
Your help is highly appreciated.

Thank You,
Got the REF cursor in storedproc.cpp.
But as it is documented, getCursor() gets the REF CURSOR value of an OUT parameter as a ResultSet.
So, is it true that if I have to write a procedure that selects * from 50 tables (50 SQL statements) , I have to set 50 OUT parameters to get the result sets.?
Is there any better way of doing this?
e.g. in DB2, we can open multiple cursors in the procedure body and then get the result set one after another.
CREATE PROCEDURE get_staging_data ()
RESULT SETS 1 <no. of result sets>
LANGUAGE SQL
BEGIN ATOMIC
DECLARE L_SQL varchar(5000);
DECLARE c CURSOR WITH RETURN TO CLIENT FOR L_STMT;
SET L_SQL = '';
SET L_SQL = 'SELECT * FROM ';
SET L_SQL = L_SQL || IN_Tab_Name ;
SET L_SQL = L_SQL || ' WHERE VERIFY_FLAG=''S'' FOR READ ONLY OPTIMIZE FOR 2000 ROWS' ;
PREPARE L_STMT FROM L_SQL;
OPEN c; < can open multiple cursors in the prodedure body>
END

My questions is:
- What would be the best practice for this type of simple stored procedures?
- Is there any alternate or is there anything i can fix in above stored proc which return multiple records?
Thank you,
Vimal

Just out of curiosity, what are you using for API or driver that doesn't support a ref cursor? Ref cursors are pretty much the defacto standard for passing multiple records out of an Oracle procedure. Oracle's ODP.NET, OLEDB, ODBC, JDBC, OCI, all support ref cursors. Chances are that if the driver you're using doesn't support something as basic/fundamental as a ref cursor, it's probably also not going to support something else either.
You'll most likely want to check with the driver/api vendor on their recommended approach.

Stored procedure that returns multiple tables

Hello everyone,
I was wondering if there's a way to write a stored procedure that returns multiple result set as in sql server. for example, in sql server, you can write 2 select statements and when loading them in c#, u can get two data tables.
I am not sure having a single ref cursor for each select is the only solution. I might need to return a variable number of tables per procedure call (based on a certain criteria).
Any ideas?
thanks for your time

Sure. Ref cursor is the only easier answer for your problem.

Multiple cursors and xmlforest

This is my first time working with XML in PLSQL. I'm trying to parse values from a plsql procedure into a Word document using XML.
My procedure looks something like:
CREATE OR REPLACE PROCEDURE GET_XML_FA
(PP_ID IN VARCHAR2,
PP_PERIOD IN VARCHAR2
IS
result CLOB;
result1 clob;
CURSOR my_cur_1 IS
   SELECT XMLForest(to_char(sysdate,'fmMonth DD, YYYY') "sysdate",
                    INITCAP(TRIM(p.p_name))||' ('||p.p_id||')' "person",
                    p_period "period",
                    (SELECT DISTINCT INITCAP(TO_CHAR(det.detail_date,'fmMonth DD,YYYY'))
                     FROM details_table det, abc_table abc, people p
                     WHERE det.fa_seq_num = abc.fa_seq_num
                     AND p.p_seq_num = abc.p_seq_num
                     AND p.p_id LIKE pp_id
                     AND REPLACE((TO_CHAR(abc.from_period,'fmMonth YYYY'))||'-'||INITCAP(TO_CHAR(abc.thru_period,'fmMonth YYYY')),' ','') LIKE pp_period
                     AND det.dtl_code = 'bill'
                     ) "bill_date"
                    ) xrow
FROM PEOPLE p
WHERE p.p_id = PP_ID;
CURSOR my_cur_2 IS
                    select XMLForest
                    (Initcap(to_char(det.detail_date,'fmMonth DD,YYYY')) "payment_date",
                     det.detail_amt "payment_amt") xrow
                    from details_table det, abc_table abc, people p
                    where det.fa_seq_num = abc.fa_seq_num
                    and p.p_seq_num = abc.p_seq_num
                    and p.p_id = pp_id
                    AND replace((TO_CHAR(abc.from_period,'fmMonth YYYY'))||'-'||INITCAP(TO_CHAR(abc.thru_period,'fmMonth YYYY')),' ','') like pp_period
                    and det.dtl_code = 'payment';
BEGIN
htp.print('<?xml version="1.0" ?>');
htp.print('<DOCUMENT DOCNAME="My_Letter'||pp_id||'_'||pp_period||'.doc" DESTINATION="'||get_const_value('FA_TRACK_DIR')||'" SOURCE="'||get_const_value('DOCBUILDER_DIR')||'" LOGFILE="'||get_const_value('FA_TRACK_DIR')||'">');
htp.print('<NOTE FNAME="My_Letter.doc">');
for my_rec_1 in my_cur_1 loop
result := my_rec_1.xrow.getClobVal();
   htp.print(result);
end loop;
for my_rec_2 in my_cur_2 loop
result1 := my_rec_2.xrow.getClobVal();
htp.print(result1);
end loop;
htp.print('</NOTE>');
htp.print('</DOCUMENT>');
END;my_cur_1 returns a single row of data whereas my_cur_2 returns multiple rows. However, while parsing values into my word document, my_cur_2 passes only the first row and doesn't pass the remaining rows.
I'm not able to understand what I am doing wrong. Can anyone help?
Note: get_const_value is our custom function that determines directory path based on server.
Let me know if more details are required.

Hi Scorpio,
my point was very simple. XMLAgg function pre-aggregates the result elements in one row. See example below with simulated dual data.
select XMLForest
(rownum "payment_date", 'a' "payment_amt" ) xrow
from dual connect by level <= 2
XROW
<payment_date>1</payment_date><payment_amt>a</payment_amt>
<payment_date>2</payment_date><payment_amt>a</payment_amt>
2 rows selected
select XMLAgg(XMLForest
(rownum "payment_date", 'a' "payment_amt" )) xrow
from dual connect by level <= 2
XROW
<payment_date>1</payment_date><payment_amt>a</payment_amt><payment_date>2</payment_date><payment_amt>a</payment_amt>
1 rows selected
If this doesn't help I'd suggest - simplify the example (consider only the cursor causing problem, use the dual table etc) and post the Oracle version.

Using XI - RFC table and an Oracle stored procedure that returns a cursor.

I need to create an interface using XI between an RFC table and an Oracle stored procedure that returns a cursor. We are on oarcle 9.2 and SP12.
My stored procedure looks something like this:
CREATE OR REPLACE
PROCEDURE testproc_xi2 (p_recordset1 OUT SYS_REFCURSOR,
                                         in_quoteid IN varchar2 )
AS
BEGIN
OPEN p_recordset1 FOR
   SELECT q.quote_id,
                 q.modified_by,
                 q.quote_status,
                 q.total_cost
            FROM quote q
           WHERE q.quote_id = in_quoteid
             AND q.total_cost > 0 ;
END testproc_xi2 ;
My RFC has table and one import parameter .
I wanted to know how to create the data type for the ref cursor? and also for the table type in the RFC?
CAN XI handle multi rows coming from a Stored procedure? Are there any other alternative methods if this is not supported?Any pointers to this would be helpful.
I have called a Oracle SP from an RFC before, but that interface had one input parameter going to the stored procedure from the RFC and about 6 o/p parameters coming from the Stored procedure. This works fine.
Thanks for the help.
Mala

Mala,
i dont think there is anything called an rfc table...RFC stands for remote function call. That in essence would imply you need a rfc to jdbc connection.
yes XI can handle multiple rows cooming from the the stored procedure if you have them mapped appropriately.
Now as to how to create the data type within xi , you need to know what fields are going to be returned and whether they are nested and then just create them as you would for an xml
for ex
<Details>
<FirstName>
<LastName>
</Details>
that in xi would be smthing like
Details type of data occurence
FirstName type of data occurence
LastName type of data occurence.
Hope that helps.
If it does dont forget the points..:-)

Select function that returns multiple columns.

Currently I have a function that will return 1 column and I can use that in a select statement. What I need is to return multiple columns from a table. In the function I have I return the street address from a table that holds information about dealers, I need to be able to also return the columns that contain the city, state, and zip code so it can be used in an sql select statement. How would I do this?
My function:
FUNCTION GET_ADDRESS(dealer_id IN number)
RETURN tbl_dealer_info.c_street%TYPE AS
v_rc tbl_dealer_info.c_street%TYPE;
CURSOR get_dealer_cur IS
SELECT c_street
FROM tbl_dealer_info
WHERE n_dealer_id = dealer_id;
BEGIN
v_rc := NULL;
OPEN get_dealer_cur;
FETCH get_dealer_cur INTO v_rc;
IF get_dealer_cur%NOTFOUND THEN
NULL;
END IF;
CLOSE get_dealer_cur;
RETURN v_rc;
EXCEPTION
WHEN OTHERS THEN
RETURN NULL;
END GET_ADDRESS;
My select statement:
select GET_ADDRESS(1205) Street, DI.n_inactive_flag, DI.n_onhold_flag
from tbl_dealer_info DI
where DI.n_dealer_id = 1205;
I would like to be able to select the street, city, state, and zip all in this select statement from the GET_ADDRESS function.
Thanks,
Lori Neirynck

"The reality is you've probably already put your blinders on and you won't learn the best approach to solving your problem because you insist on asking a courtroom style question (just "yes" or "no" please)."
Actually, I asked this question because I was looking for the best approach to my problem. I have an SQL statement that correctly selects everything it needs to from all 15 tables. The thing of it is it is very long and difficult to read. I wanted to try using functions so that I could change 12 AND/OR statements into 3 IF statements so everything is easier to read. I have received a couple of different ways to do this from other forums that assumed I knew what I was doing. I have gotten one to work, the other I'm still working on. I'll post the one that worked for others that want to know.

PLSQL web service returning multiple records

Hello,
I am trying to create a web service using oracle 11g which should be able to return multiple records.
Based on hints and code samples found on the internet here is my code :
CREATE OR REPLACE TYPE test_rec is OBJECT (
    s_nume_adre                    NUMBER ,
    c_eta_civi                     VARCHAR2(4 BYTE),
    l_nom1_comp                    VARCHAR2(40 BYTE),
    l_nom2_comp                    VARCHAR2(40 BYTE),
    l_nom3_comp                    VARCHAR2(40 BYTE),
    l_pren_comp                    VARCHAR2(30 BYTE),
    d_date_nais                    DATE);
CREATE OR REPLACE TYPE test_array AS TABLE OF test_rec;
CREATE OR REPLACE PACKAGE test_pkg AS
function get_rows(snume_adre in number) return test_array;
END;
CREATE OR REPLACE PACKAGE BODY test_pkg AS
function get_rows(snume_adre in number) return test_array is
    v_rtn   test_array := test_array(null);
    v_first boolean := true;
    cursor c_get_rows(snume_adre in number) is
      SELECT a.s_nume_adre,
             nvl(a.c_eta_civi, '') c_eta_civi,
             nvl(a.l_nom1_comp, '') l_nom1_comp,
             nvl(a.l_nom2_comp, '') l_nom2_comp,
             nvl(a.l_nom3_comp, '') l_nom3_comp,
             nvl(a.l_pren_comp, '') l_pren_comp,
             nvl(a.d_date_nais, to_date('01.01.1900', 'dd.mm.yyyy')) d_date_nais
    FROM bro.z45 a
where a.s_nume_adre = snume_adre or snume_adre is null;
begin
    for rec in c_get_rows(snume_adre) loop
      if v_first then
        v_first := false;
      else
        v_rtn.extend;
      end if;
    v_rtn(v_rtn.last) := test_rec(rec.s_nume_adre, rec.c_eta_civi, rec.l_nom1_comp, rec.l_nom2_comp,
                                rec.l_nom3_comp, rec.l_pren_comp, rec.d_date_nais);
    end loop;
    return v_rtn;
end;
END;
--select * from table (test_pkg.get_rows(null));
I am able to retrieve the data using the select.
However when I try to access its wsdl I get an error :
<soap:Envelope>
   <soap:Body>
      <soap:Fault>
         <faultcode>soap:Client</faultcode>

Any hint as how to create and access pl sql web service returning multiple rows?
I don't use java and don't have access to tools like JDeveloper.
Thanks!

The actual issue is that collection types are not supported for return parameters.
The solution is to wrap the collection into another object.
Here's a working example based on your settings :
CREATE OR REPLACE TYPE test_rec is OBJECT (
empno number(4)
, ename varchar2(10)
, hiredate date
CREATE OR REPLACE TYPE test_array AS TABLE OF test_rec;
CREATE OR REPLACE TYPE test_array_wrapper is OBJECT ( arr test_array );
CREATE OR REPLACE PACKAGE test_pkg AS
function get_rows(p_deptno in number) return test_array_wrapper;
END;
CREATE OR REPLACE PACKAGE BODY test_pkg AS
function get_rows(p_deptno in number) return test_array_wrapper is
    results test_array;
begin
    select test_rec(empno, ename, hiredate)
    bulk collect into results
    from scott.emp
    where deptno = p_deptno;
    return test_array_wrapper(results);
end;
END;
The wsdl is then generated correctly :
SQL> select httpuritype('http://DEV:dev@localhost:8080/orawsv/DEV/TEST_PKG/GET_ROWS?wsdl').getxml() from dual;
HTTPURITYPE('HTTP://DEV:DEV@LOCALHOST:8080/ORAWSV/DEV/TEST_PKG/GET_ROWS?WSDL').GETXML()
