Having a SP or Function return a set of rows ?

Hi,
I been looking through the documentation that came with PL/SQL and I am trying to figure out how to get a procedure or function to return the rows of a select statement. Would it have to be done using a Table function ?? I am trying to access the results of a procedure that does some pre-processing before returning the results of the query in a JDBC application..
Thanks

You can't return the rows of a SQL query through PL/SQL.
You need to create one or more functions that are called in your select statement to perform the pre-processing i.e.
select function1(param1), function2(param2)
from ...

Function returning a set of records - how to do this?

Hi,
I need to return something of a table as a result:
function Find_Item (vNUMBER in NUMBER(3,0)
vNAME in VARCHAR2(200) ) return ???
as
begin
SELECT UUID, Number, Name FROM Tab1
Where NUMBER LIKE vNUMBER|| '%'
intersect
SELECT UUID, Number, Name FROM Tab1
Where NAME LIKE vNAME|| '%' ;
end;
How to do this? Should I use a collection? Any ideas? I would be grateful for any hint.
Best regards,
Alicja

And it would work if not for INTERSECT. So, I either I change the query or have to find walk-around.What is the issue with the INTERSECT? Why should the approach shown not work when using INTERSECT?
Note that you can't define the parameters of your function like that, you have to specify the length of the varchar2 column in the calling code.
If your query is going to return potentially a large number of rows you should consider using a "pipelined" function, as already mentioned, as the non-pipelined version could be consuming a lot of memory in case a large collection is going to be generated.
Here's a sample of a pipelined table function:
alter session set nls_language = 'AMERICAN';
set echo on linesize 130 feedback 1
drop type t_find_item_record_col force;
drop type t_find_item_record force;
drop function find_item;
create or replace type t_find_item_record as object(
uuid varchar2(30),
a_number number,
a_name varchar2(30)
create or replace type t_find_item_record_col as table of t_find_item_record;
create or replace function find_item(
vNUMBER in NUMBER, vNAME in VARCHAR2) return t_find_item_record_col pipelined
as
a_find_item_record_col t_find_item_record_col;
cursor c is
select t_find_item_record(uuid, a_number, a_name) from (
SELECT cast('a' as varchar2(30)) as UUID, 1 as a_Number, cast('b' as varchar2(30)) as a_Name
FROM dual
Where 35 LIKE vNUMBER|| '%'
intersect
SELECT 'a' as UUID, 1 as a_Number, 'b' a_Name FROM dual
Where 'Bob' LIKE vNAME|| '%'
begin
open c;
loop
    fetch c bulk collect into a_find_item_record_col limit 100;
    for i in 1..a_find_item_record_col.count loop
      pipe row(a_find_item_record_col(i));
    end loop;
    exit when a_find_item_record_col.count = 0;
end loop;
close c;
return;
end;
select * from table(find_item(35, 'Bob'));Another option you might want to consider is using a REF CURSOR return type, so that you open the cursor accordingly in your function and return the opened cursor to the caller. The caller can then fetch from this cursor.
And here's a sample function using ref cursor:
create or replace function find_item_cursor(
vNUMBER in NUMBER, vNAME in VARCHAR2) return sys_refcursor
as
c sys_refcursor;
begin
open c for
SELECT cast('a' as varchar2(30)) as UUID, 1 as a_Number, cast('b' as varchar2(30)) as a_Name
FROM dual
Where 35 LIKE vNUMBER|| '%'
intersect
SELECT 'a' as UUID, 1 as a_Number, 'b' a_Name FROM dual
Where 'Bob' LIKE vNAME|| '%';
return c;
end;
variable a refcursor
exec :a := find_item_cursor(35, 'Bob')
print aHere's the output of the samples:

Returning a set of registers in a PL/SQL function

Does anybody knows if there is some way to return a set of registers (like a cursor) in a PL/SQL function without using a temporary table?
Thank you

Hi: Nei S
Create a Package first:
CREATE OR REPLACE PACKAGE sp_xxxPKG AS
TYPE RT1 IS RECORD (
sp_col1 emp.emp_no%TYPE,
sp_col2 emp.emp_name%TYPE);
TYPE RCT1 IS REF CURSOR RETURN RT1;
END;
Then Create a Procedure:
CREATE OR REPLACE PROCEDURE sp_xxx (
RC1 IN OUT sp_xxxPKG.RCT1) AS
BEGIN
OPEN RC1 FOR
SELECT emp_no, emp_name FROM emp;
RETURN;
END;
null

Problem with Function returned without value -

all i am having a problem w/ jdev passing the values. when hardcoded it works. when i remove to pass the 2 vals for doc_type and doc_num the params are being passed to the impl but the String sql = " BEGIN :5 := scotts_test_proc.get_log(:1, :2, :3, :4 ); END; "; is not sending the values to the pkg. to verify i am getting data i created a table to store the data being passed/retrieved by function. i am getting the log_pieces posted when hard coded so i know that works. but when i try to pass the doc_type and doc_num it errors w/ function returend without value . am i passing the params correctly from co to impl to func to get the return l0g_piece. thats for the help

Issue with running PL/SQL function returning Sql query

hi, I am trying to create a report region by using the option of PL/SQL function returning sql query.
I notice that it's very slow for the report region page to show up. In my PL/SQL function body, there are only 3 steps, first update all the 10 rows of varchar2 fields to null,then insert values to those fields, then select all from the table to show report results. It takes more than 5 minitues for the page to load up, how ever, if i run those steps in SQL*Plus, it only takes a couple of seconds to finish. Any suggestions?
Thanks,
gina

Sergio, the codes are as followed,
Declare
q varchar2(32767); -- query
Begin
q := 'select "ID",'||
'"ENTRY NAME","TOTAL","#CM","%CM","#CA",'||
'"%CA", from Info_table';
update info_table
set "TOTAL" = '',
"#CM" = '',
"%CM" = '',
"#CA" ='',
"%CA"=''
where "ID"<=10;
// set all data in column Total to null,there is only 10 rows in the table
update info_Table set Total = vTotal,
"#CM" = vCM
(those variables hold user key-in Text filed value)
where ID = 1;
return q;
End;

Why does getdate() function return same time value for multiple select statements executed sequentially

When I run the following code
set nocount on
declare @i table(id int identity(1,1) primary key, sDate datetime)
while((select count(*) from @i)<10000)
begin
insert into @i(sDate) select getdate()
end
select top 5 sDate, count(id) selectCalls
from @i
group by sDate
order by count(id) desc
I get the following results.
sDate selectCalls
2014-07-30 14:50:27.510 406
2014-07-30 14:50:27.527 274
2014-07-30 14:50:27.540 219
2014-07-30 14:50:27.557 195
2014-07-30 14:50:27.573 170
As you can see the select getdate() function returned same time up to the milisecon 406 time for the first date value. This started happening when we moved our applications to a faster server with four processors. Is this correct or am I
going crazy?
Please let me know
Bilal

Observe that adding 2 ms is accurate only with datetime2. As noted above, datetime does not have ms resolution:
set nocount on
declare @d datetime, @i int, @d2 datetime2
select @d = getdate(), @i = 0, @d2 = sysdatetime()
while(@i<10)
begin
select @d2, @d, current_timestamp, getdate(), sysdatetime()
select @d = dateadd(ms,2,@d), @i = @i+1, @d2=dateadd(ms,2,@d2)
end

APEX, BI Publisher and SQL Query (PL/SQL Function returning SQL Query)..

I don't know if I should be posting this in this Forum or the BI Publisher forum, so I am posting in BOTH forums..
I love APEX, let me say that first.. And appreciate the support offered here by the group, but am running int a confusing issue when BI Publisher tries to build a report from the above type APEX report..
Here is my dilemma:
I have a number of reports that are part of a Oracle package. They return an SQL Query back to a reports region on a page. I am having to deal with the column names returned are col01, col02..
The issue I have is, when building the Application Level query to download the XML sample from in building RTF layouts in Word, you can not use this code, you MUST use a standard SQL Select.
I have taken the sql from the function returning sql, and copied into the application query, supplying the required data values for bind variables being used in the query.
An XML file is produced, and I use this to build the RTF format file that I load back into APEX and try to use it for the PDF rendering of the report. I can view the output as a PDF in the Word add on, but when I try using it with the report, it is returning an empty PDF file.
Can anyone tell me what error log files on the bi publisher side I can look at to see what error is happening?
Thank you,
Tony Miller

Title changed, maybe SOMEONE has an idea on this??

Hi,
1/ first check you are passing the bind variables and
appropriate values in the call to your report - if
the query returns no data then you get an empty page
So if your query takes :P10_USERNAME variable then
pass it to the report in the URL
f?p=&APP_ID.:0:&SESSION.:PRINT_REPORT=YOUR_REP_QUERY_N
AME:::P10_USERNAME:MYUSER
2/ try to use the Default layout first to check your
report query really returns the data when called
3/ if you defined a header in your rtf template check
there is no & (ampersand) - if using & in the header
and preview the template from word it displays data
OK, but if you use this template in the report query
it fails to render the data (bug in Apex-> Bi
Publisher integration maybe?)
4/ If using the table in the rtf template check its
width does not overflow the page margins - there is a
problem with pdf export
5/ check
/oc4j/j2ee/home/application-deployments/xmlpserver/app
lication.log forthe information on BI Publisher runs
RadoIssue was in the APEX page having issues.. I recoded a new page and am able to generate BI Publisher based PDF files..
Thank you,

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?

Column order in SQL Query (PL/SQL function returning a query)

Hi,
when I define a PL/SQL function returning a query inside a region, I often find that the column order is arbitrarily changed.
How do I enforce the column order ?
Bye,
Flavio

I removed the 11th column called service_name from this dynamic query: and now the report says: report error:
ORA-01403: no data found. I messed around with the Headiuns Type. It was set to Custom. I changed it to Column Names. There is no difference.
I am not sure how to fix?

How to use stored procedure which returns result set in OBIEE

Hi,
I hav one stored procedure (one parameter) which returns a result set. Can we use this stored procedure in OBIEE? If so, how we hav to use.
I know we hav the Evaluate function but not sure whether I can use for my SP which returns result set. Is there any other way where I can use my SP?
Pls help me in solving this.
Thanks

Hi Radha,
If you want to cache the results in the Oracle BI Server, you should check that option. When you run a query the Oracle BI Server will get its results from the cache, based on the persistence time you define. If the cache is expired, the Oracle BI Server will go to the database to get the results.
If you want to use caching, you should enable caching in the nqsconfig.ini file.
Cheers,

Can Function Return more than One Values ??

Hi Experts,
I would like to ask you Can Function Return more than one values. I Used Function with Out and In out parameter and its working Fine..
1. what is harm using Out and In out parameter in function
2. if we can use Out and In out parameter in Function so what is deffernce between procedure and Function.
3. Is there any Other Way Though which we can return more the One values in Function.
Please advice me...
Thanks
Umesh Goel

Yes/No.
You can return multiple value from function. But, in PL/SQL and not in a SQL.
