Functions returning records

I have a function that returns a record, a row type from a table I selected
In a procedure I now try to call values from this function by calling
function.value1
however I get the error
subprogram or cursor 'function' reference is out of scope
does anyone know what is wrong?
thanks

I can only provide some pattern
-- your function:
create or replace function your_function(p_param(s) in data_type) return your_table%rowtype is
return_value your_table%rowtype;
begin
< your processing here (return_value gets a value assigned) >
return return_value;
end;
-- your procedure:
create or replace procedure your_procedure(p_param(s) in data_type) is
function_value your_table%rowtype;
some_variable data_type;
begin
< your processing here >
function_value := your_function(p_param(s));
some_variable := function_value.rowtype_column_name;
end;Regards

Can stored function return record type or cursor type?

Hi everybody,
I am working with a stored function now.
Can the function output more that ONE result? i.e. cursor or record type.
Thanks.
Brigitta.

Brigitta,
If you are calling the stored function from SQL then the function can only return one of the base datatypes, as Murali has said. However, if you are calling the function from PLSQL you can return any complex datatype, eg:
package test_package is
type rec_test is
( col_a number
, col b varchar2(30) );
type tab_test is
table of rec_test
index by binary ineteger;
function test_function (.....)
return tab_test;
end test_package;and to call this function:
declare
l_table test_package.tab_test;
begin
l_table := test_package.test_function(....);
end;Hope that helps!

Function return single record

create or replace function etest
(dep in number)
return varchar2
is
dept number:= 0;
cursor c1 is
select deptno
into dept
from emp
where deptno = dep;
begin
open c1;
loop
fetch c1 into dept;
exit when c1%notfound;
end loop;
close c1;
return dept;
end;
Dear all
the above function return only one return ,,,but i want to display all record that belong to department 10
it just i idea that what i want to do....!
and Secondly
how i fetch multiple column like i enter department 10 and it give output like
empno ename sal

You could use a REF CURSOR:
PL/SQL 101 : Understanding Ref Cursors
http://www.oracle-base.com/articles/misc/UsingRefCursorsToReturnRecordsets.php
or maybe a pipelined function....

Custom function to return Record Selection Criteria

Here's what I need to do. There will be two prompts for range of dates; say, Begin date and End Date on almost all of the reports here. But it is not mandatory to enter Begin Date nor end date. So depending on the data the user enters we have to build the where clause.So, to achive this I am trying to write a custom function which accepts the column name , and data from the parameters in the report. my_func(col_nme, bgn_date, end_date) .. This function does all the validations and returns a string depending on the data entered by the user. Eg., if user entered only begin date then it will return col_nme <= bgn_date if user entered both dates then col_nme between bgn_date and end_date And I am trying to user this complete clause in my record selection of the report. In Record Selection call my_func({Query.Eff_date},p_bgn_date,p_end_date) It is not accepting it since the function returns it as a string and the Reord selection should return a bolean. Can any one let me know how to get this functionality in my report.  ANy other suggestions to achieve this would be a great help Thanks a lot in advance. 

as long as you have discrete and multi values checked on for the parameter, the resulting array is all you need.
In the RSF, the desired results will be returned by a REALLY simple boolean statement
{table.field} in {?my param}
"Like" may replace "in"Â for some cases.
Try it, you'll like it.Â :)Â

Oracle 11g Table function returns no records on first call

Hello,
On a Oracle 11g R2 I've a table function ( PIPELINED ) returning rows selected from a table.
The first time the function is selected, in a session ( I've tried to disconnect and log in again ), it returns no rows.
I've tried to log the call using DBMS_OUTPUT and from what I see the select on the table function returns no rows and no output is printed. So I presume Oracle is not calling the function.
The same function on a similar environment ( same db versions, patches and database structure ) works fine. The second environment is a production environment so it has more memory and some other settings enabled.
Does anyone know of settings that can relate to this behaviour ?
Thanks in advance for the help.
Regards,
Stefano Muret

Thank you for answering so fast.
Here's the function code:
FUNCTION template_parameters (iTemplate IN TEMPLATE_RAW_DATA.TMPL_ID%TYPE := NULL)
RETURN table_type_tmpl_parameters PIPELINED
IS
li_exception INTEGER DEFAULT -20025;
POUT_PARM TABLE_TYPE_TMPL_PARAMETERS;
lt_parms table_type_tmpl_parms_raw;
sParmCheck VARCHAR2(4000);
iOccurrence INTEGER;
BEGIN
pOut_Parm := table_type_tmpl_parameters();
pOut_Parm.EXTEND;
select
tmpl_id
*,tmpl_name*
*,replace(upper(trim(sql_out)),'[SCHEMA].')*
*,UPPER(TRIM(out_tmpl_parms))*
bulk collect into lt_parms
from ref_templates
where tmpl_id = NVL(iTemplate,tmpl_id)
order by tmpl_id;
FOR k IN 1..lt_parms.COUNT
LOOP
pOut_Parm(1).tmpl_id := lt_parms(k).tmpl_id;
pOut_Parm(1).tmpl_name := lt_parms(k).tmpl_name;
FOR i IN 1..2
LOOP
IF i = 1 THEN
sParmCheck := lt_parms(k).sql_out;
ELSE
sParmCheck := lt_parms(k).sql_parms;
END IF;
iOccurrence := 1;
*pOut_Parm(1).parameter_name := regexp_substr(sParmCheck,'\[[^\[]+\]',1,iOccurrence);*
WHILE pOut_Parm(1).parameter_name IS NOT NULL
LOOP
PIPE ROW (pOut_Parm(1));
iOccurrence := iOccurrence + 1;
*pOut_Parm(1).parameter_name := regexp_substr(sParmCheck,'\[[^\[]+\]',1,iOccurrence);*
END LOOP;
END LOOP;
END LOOP;
RETURN;
EXCEPTION
WHEN OTHERS THEN
RAISE_APPLICATION_ERROR(li_exception,SUBSTR(SQLERRM,1,1000));
RETURN;
END template_parameters;
This function is part of a package.
The data on both environments is the same.

Return records from Stored Procedure to Callable Statement

Hi All,
I am createing a web application to display a students score card.
I have written a stored procedure in oracle that accepts the student roll number as input and returns a set of records as output containing the students scoring back to the JSP page where it has to be put into a table format.
how do i register the output type of "records" from the stored function in oracle in the "registerOutParameter" method of the "callable" statement in the JSP page.
if not by this way is there any method using which a "stored function/procedure" returning "record(s)" to the jsp page called using "callable" statement be retrieved to be used in the page. let me know any method other that writing a query for the database in the JSP page itself.

I have a question for you:
If the stored procedure is doing nothing more than generating a set of results why are you even using one?
You could create a view or write a simple query like you mentioned.
If you're intent on going the stored procedure route, then I have a suggestion. Part of the JDBC 2.0 spec allows you to basically return an object from a CallableStatement. Its a little involved but can be done. An article that I ran across a while back really helped me to figure out how to do this. There URL to it is as follows:
http://www.fawcette.com/archives/premier/mgznarch/javapro/2000/03mar00/bs0003/bs0003.asp
Pay close attention to the last section of the article: Persistence of Structured Types.
Here's some important snippets of code:
String UDT_NAME = "SCHEMA_NAME.PRODUCT_TYPE_OBJ";
cstmt.setLong(1, value1);
cstmt.setLong(2, value2);
cstmt.setLong(3, value3);
// By updating the type map in the connection object
// the Driver will be able to convert the array being returned
// into an array of LikeProductsInfo[] objects.
java.util.Map map = cstmt.getConnection().getTypeMap();
map.put(UDT_NAME, ProductTypeObject.class);
super.cstmt.registerOutParameter(4, java.sql.Types.STRUCT, UDT_NAME);
* This is the class that is being mapped to the oracle object.
* There are two methods in the SQLData interface.
public class ProductTypeObject implements java.sql.SQLData, java.io.Serializable
    * Implementation of method declared in the SQLData interface. This method
    * is called by the JDBC driver when mapping the UDT, SCHEMA_NAME.Product_Type_Obj,
    * to this class.
    * The object being returned contains a slew of objects defined as tables,
    * these are retrieved as java.sql.Array objects.
     public void readSQL(SQLInput stream, String typeName) throws SQLException
        String[] value1 = (String[])stream.readArray().getArray();
        String[] value2 = (String[])stream.readArray().getArray();
     public void writeSQL(SQLOutput stream) throws SQLException
}You'll also need to create Oracles Object. The specification for mine follows:
TYPE Detail_Type IS TABLE OF VARCHAR2(1024);
TYPE Product_Type_Obj AS OBJECT (
value1 Detail_Type,
value2 Detail_Type,
value3 Detail_Type,
value4 Detail_Type,
value5 Detail_Type,
value6 Detail_Type,
value7 Detail_Type,
value8 Detail_Type);Hope this helps,
Zac

Report- Pl/sql function returning sql query parsing page items as text?

Hi Team,
I am facing a strange issue .
I have four page items namely
1)JOB_CODE
2)MIN_EXP
3) MAX_EXP
4) SOURCES1
I have a report of the type "Pl/sql function returning sql query"
declare
v_sql varchar2(4000);
begin
if (:JOB_CODE IS NOT NULL and :MIN_EXP IS NOT NULL and :MAX_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql:= 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = :JOB_CODE and v_experience_years >= :MIN_EXP and v_experience_years <= :MAX_EXP and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
elsif (:JOB_CODE IS NULL and :MIN_EXP IS NOT NULL and :MAX_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql := 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where v_experience_years >= :MIN_EXP and v_experience_years <= :MAX_EXP and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
elsif (:MIN_EXP IS NULL and :JOB_CODE IS NOT NULL and :MAX_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql := 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where v_experience_years <= :MAX_EXP and V_REQUIREMENT = :JOB_CODE and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
elsif (:MAX_EXP is null and :JOB_CODE IS NOT NULL and :MIN_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql := 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = :JOB_CODE and v_experience_years >= :MIN_EXP and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
end if;
insert into query_list values (v_sql);
insert into debug values (:JOB_CODE , :MIN_EXP , :MAX_EXP , :SOURCES1);
return v_sql;
end;
Please not that I am insertin the query into a table called Query_list and the page item values into the table called Debug thru the pl/sql function which returns teh query.
Now I select the data from the debug tables.
select unique(query) from query_list;
select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = :JOB_CODE and v_experience_years >= :MIN_EXP and v_experience_years <= :MAX_EXP and source like '%:SOURCES1%'
select * from debug;
JOBCODE MINEX MAXEX SOURCE
21 1 10 donkeyHire
And if I run the query in sql I get some records returned
select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = 21 and v_experience_years >= 1 and v_experience_years <= and source like 'donkeyHire'
V_CANDIDATE_ID V_FNAME V_CURRENT_EMPLOYER V_EXPERIENCE_YEARS
2 Vengu Andale Tech 4
But the record does not show up in the report!
does this type of report parse page items as text?
Why is it so?
Waiting for an early reply.
Thanks,
venkat

Venkat - You don't want to put ':SOURCES1' in quotes like that.

On Submit process not firing -report (PL/SQL function returning SQL query)

Can anyone suggest possible causes / solutions for the following problem?
I have a report region that uses a PL/SQL function returning SQL query. The report allows the user to update multiple fields / rows and then click a button to submit the page which should run the On-Submit process to update the database. However the process does not run and I get a 'HTTP404 page cannot be found' error; and when I navigate back using the Back button I cannot then navigate to any other page in my application without getting the same error. The button was created by a wizard selecting the options to submit the page and redirect to a (same) page. The button does not actually have a redirect in its definition but the wizard created a branch to the same page which should work and the button has the text 'submit as SUBMIT' next to it so it appears to be set up correctly.
I have recreated this page several times in my application and I cannot get the On-Submit process to run. However I have created a cut down version of the same page in the sample application on apex.oracle.com at http://apex.oracle.com/pls/otn/f?p=4550:1:179951678764332 and this works perfectly so I am at a loss to understand why it does not work in my application. I cannot post any part of the application itself but if anybody would like to check out page 30 of the sample application (Customer Update Test tab) updating the surnames only, using credentials ja, demo, demo this is pretty much what I have got in my application.
Any ideas would be much appreciated?

Thanks for the suggestions guys. I have now identified that the problem goes away when I remove the second table from my report query. The original report query retrieved data from two tables and the process was updating only one of the tables. I thought I had approached the task logically i.e. first get the report to display the records from the two tables, then get the process to update the first table and finally to modify the process further to update the second table.
Can anyone point me to an example of multiple row updates on multiple tables using a PL/SQL function returning an SQL query?

Function returning query takes more time to run in Apex4.0

Hi All,
I created a report using function returning query. The function returns query based the parameters which returns dynamic columns. When I run the query in sql developer the query generates and returns the result in 3mins. But in apex it takes maximum of 35mins to return.
The query will return around 10000 rows.
Is it a performance issue in the query or in Apex?can anyone please help

Hi Roel,
Thanks much for your suggestion. I run in TOAD and got the result as
Row 1 of 500 fetched so far in 3.31 minutes which means it queried for 500 records alone ? is that not the actual time taken to run the fulll query?That reflects the time to return the first 500 records...
Please suggest.With all the best will in the world, if I was your user and I had to wait 3 minutes for the page to refresh, I'd steadily lose the will to live!
As this is primarily an SQL tuning question, have a look at this message in the FAQ thread in the {forum:id=75} forum:

Does a table/view still return records if the underlying VPD policy fails ?

Hi All,
I have one following question -
Does a table or view still return records if the underlying VPD policy fails?
I am adding one more thing here. Let us say security is being implemented using the application context and VPD.
What would happen when application context is not set ? Would the application apply any default privilege as VPD?
Thanks,
Ashi

If you are truly setting a VPD, you have to make sure that the context is set and the condition variable are passed through it. This is normally done through a logon trigger so again, generically , its not possible that it would not be set. I didn't get at all what ever you said in the last line? What is "default priv for VPD" ?

How do i skip a line if a function returns 0

Currently i am producing a report that was passed a starting point parameter. Meaning i want an hourly wage above this number. Now in the report i run the following function. Now if the number the function return is less than 5 then i do not what that line/record to display in the report. Can anyone tell me where to look to understand how to accomplish this.
howard
function WAGE_TYPEFormula return Number is
my_num number(10)
begin
IF :salary_type = 'BIWEEKLY' then
               return :salary / 80;
end if;
IF :salary_type = 'MONTHLY' then
               return :salary / 173.34;
end if;
IF :salary_type = 'ANNUAL' then
               return :salary / 2080;
end if;
IF :salary_type = 'HOURLY' then
     return :salary;
end if;
IF :salary_type IS NULL then
               return 0;
end if;

U need to use a lexical parameter
Go to data model and add a user paranmeter of name say
test_param . Make sure the characer size is adequate
and in your function have this parameter
:test_param := 'whateever u want or dont want to display'
and in the design model include a field with source "test_param"
during runtime the report will display whtever is in test_param

Why oracle function return 4000 characters ?

Dear All
When I write any function to get some return value in a query, its width is set to 4000. Moreover, when i write the same query to create any LOV, it gives an error that record group field cannot be greater than 2000. Where the actual width of this field is 200 characters.
Why function always returns 4000 characters?
Regards
Edited by: OraLearner on Dec 1, 2010 11:47 AM

Because the maximum of a varchar2 in SQL is 4000 and you have no dimension in your function:
SQL> r
1 create or replace function myfunc(inMaxVal in number) return varchar2 is
2    vRet varchar2(32000);
3 begin
4    for i in 1..inMaxVal loop
5      vRet := vRet || '1';
6    end loop;

[HELP] Procedure return records

Hi All,
I want to create a procedure that will return records (not only single record) base on some parameters. Is it possible?
While i used MS SQL Server, it is just a simple way. In the body of procedure i just need to call select query with some parameters in where clause. For example:
Create procedure GetEmployee
@grade char(1)
As
Select * From Employee Where EMP_Grade=@grade
Please help me!

First off, what are you going to do with the records that are returned here?
Second, you can return a REF CURSOR
CREATE OR REPLACE PACKAGE refcursor_demo
AS
TYPE emp_refcursor_strong IS REF CURSOR RETURN emp%rowtype;
TYPE emp_refcursor_weak   IS REF CURSOR;
-- You can define either procedures that have the strongly typed
-- REF CURSOR as an OUT parameter or you can define a function that
-- returns the REF CURSOR.
PROCEDURE refCursorProc( employees OUT emp_refcursor_strong );
FUNCTION refCursorFunc RETURN emp_refcursor_weak;
END;
CREATE OR REPLACE PACKAGE BODY refcursor_demo
AS
PROCEDURE refCursorProc( employees OUT emp_refcursor_strong )
AS
BEGIN
    OPEN employees FOR
      SELECT * FROM emp;
END;
FUNCTION refCursorFunc RETURN emp_refcursor_weak
IS
    out_cursor emp_refcursor_weak;
BEGIN
    OPEN out_cursor FOR
      SELECT * FROM emp;
    RETURN out_cursor;
END;
END;Alternately, you could return a collection, potentially in a pipelined table function.
