I have a stored procedure in 10g that I am trying to call from Report Builder 10.1.2.0.2

Below is the sproc
// declared in the package definition
type refCursorXX is ref cursor;

//from the package body
procedure READ_AUCTIONS(Out_Cursor out refCursorXX) as
begin
open out_cursor for
select auctionid, name || ' ' || year auctionname
from auction
order by auctionends desc;
end READ_AUCTIONS;

and the PL/SQL in Reports Builder:
function QR_1RefCurDS return pkg_auction_crux.refCursorXX is
refcur pkg_auction_crux.refCursorXX;
begin
pkg_auction_crux.READ_AUCTIONS(refcur);
return refcur;
end;

When I attempt to create a report w/ report wizard I get the following error
REP-1285 Query QR_1 has no select elements.

I have searched the internet and only found 2 hit mentioning this error and no solution.
Can someone please help

I'm not sure you can create a report based on a stored procedure that returns a ref cursor.

OK you can use stored proc from an oracle database in Reports Builder and here is the trick
in you oracle package definition you MUST define a type RECORD with the datatype you want the cursor to return and define the cursor
like this.

package pkg_auction_crux as

type auction_rec is RECORD
( auctionid number,
auctionname varchar(50));
type auction_cur is ref cursor RETURN auction_rec;

procedure READ_AUCTIONS2(Out_Cursor IN OUT auction_cur);
end pkg_auction_crux;

Then in the package body define your stored procedure
procedure READ_AUCTIONS2(Out_Cursor IN OUT auction_cur) AS
BEGIN
open out_cursor for
select auctionid, name || ' ' || year auctionname
from auction
order by auctionends desc;
END READ_AUCTIONS2;

Notice I am selecting the exact field IN ORDER into the record type i definded in the package definition by using the cursor

Then in Reports Builder
define a PL/SQL query as follows

function QR_1RefCurDS return pkg_auction_crux.auction_cur is
refcur pkg_auction_crux.auction_cur;
begin
pkg_auction_crux.READ_AUCTIONS2(refcur);
return refcur;
end;

Notice the return type of the procedure is the fully qualified name of the ref cursor you defined in you package definition

I declare a variable named refcur to be of that type
and then call the stored procedure passing it my defined refcur
then return it from the procedure

Problem Solved!

Now we extend this out so that the sproc will take a user parameter passed to the report

first alter the sproc in oracle database to accept an input parameter
procedure READ_AUCTIONS2(Out_Cursor IN OUT auction_cur, IN_AUCTIONID IN NUMBER) AS
BEGIN
open out_cursor for
select auctionid, name || ' ' || year auctionname
from auction
WHERE AUCTIONID = IN_AUCTIONID
order by auctionends desc;
END READ_AUCTIONS2;




Then I define a user parameter in Reports Builder called IN_AUCTIONID with a type number

Then edit the PL/SQL statement in the above post to pass the user parameter to the stored procedure

function QR_1RefCurDS return pkg_auction_crux.auction_cur is
refcur pkg_auction_crux.auction_cur;
begin
pkg_auction_crux.READ_AUCTIONS2(refcur, :IN_AUCTIONID);
return refcur;
end;

Easy Squezzy!

Thank you, Mark! It seems that today I learnt something new. I'll have to try it, once.

Hello Mark!

I have a pagkage in oracle 10g which contains a function returning a ref cursor in Oracle 10g.

In the Oracle reports I have selected the 'ref cursor query' and created the required query.
The query is compiled perfectly.
But at run time it is generating the REP-1285 error.

Also there are no fields displayed in the data model.

Please give me some solution.

Thanks,

Erne

It seems that you did something wrong.

Oracle

REP-1285: Query '<query name>' has no select elements.

Cause: Your data model contains a query that does not select anything. Each query in your data model must select at least one element.

Action: Enter a SELECT statement in the query, selecting at least one element.
