As a follow-up to the question "Get resultset from oracle stored procedure", is there a way to show the results of a stored procedure that returns a REFCURSOR in a grid (instead of the plain text Script Output window) within SQL Developer?
EDIT: The answer helped, but I'm still having a problem displaying the result set in the "View Value" window:
The columns can only be expanded a small amount, probably due to the number of results being returned. Expanding the window with the resizer control doesn't help:
I don't think you can with a procedure.
Edit: Thanks to DCookie for simplifying my original answer.
But as a work-around you can write a function that calls the procedure and then invoke that using SQL.
e.g.
create or replace function callmyproc
return sys_refcursor
IS
rc sys_refcursor;
BEGIN
myproc(rc);
return rc;
END;
Which you can then call with:
select callmyproc()
from dual;
When this example is run, the SQL Developer data grid shows one result but if you scroll right and click on the edit button, you will see the results in a grid.

I am trying to display the results of a query in a region. However, the region just displays "New" and not the actual output. Could you please help?
PL/SQL code:
DECLARE
V_APP_COUNT NUMBER;
BEGIN
SELECT COUNT(*) INTO V_APP_COUNT FROM APPLICATION;
DBMS_OUTPUT.PUT_LINE(V_APP_COUNT);
END;
Query you posted suits better to a report (pick any you want - interactive, classic or grid), not to PL/SQL Dynamic Content. It expects from you to actually "draw" the page using HTML code. Basically, your PL/SQL would use htp.p calls in order to display the result.
As I said - use a report.
I'm new to Oracle, and I use Toad Data Point to create and test stored procedures.
I created this simple stored procedure:
CREATE OR REPLACE PROCEDURE dummy_sp (
p_recordset OUT SYS_REFCURSOR) AS
BEGIN
OPEN p_recordset FOR
select sysdate, user from dual;
END dummy_sp ;
/
I executed this, and the result from Toad is Executed Successfully.
Now, I would like to view the results of this stored procedure. In Toad Data Point I type the following:
variable mycursor refcursor;
call dummy_sp ( :mycursor );
I get a popup asking for a parameter. I click OK and I get the error ORA-00900: invalid SQL statement.
How can I see the result of SP dummy_sp in Toad Data Point?
In SQL Server I can run exec usp_sales and see the results of a select statement. There has to be something like that in Oracle and Toad, right?
Here you go, using Toad Data Point.
Execute the stored procedure with a bind variable in it, like :mycursor, and then make sure to configure the type as CURSOR and direction as OUT when Toad Data Point prompts you for the bind variable settings.
Here's the result:
Finally, if you wish to avoid the popup for bind variables, you can execute the procedure directly from the object explorer:
Right-click the procedure and choose Operations / Execute Procedure, and Toad will run it, without prompting for data type.
In case you need a workaround while you wait for help with your tool, the default, free IDE for Oracle Database makes this pretty easy.
If you execute the program using the code editor, it will automatically grab any outputs, whether those be OUT params or RETURNs from a function, including your refcursor
Or if your GUI has proper SQLPlus script execution support (SQL Developer does, not sure about your program):
var x refcursor
exec dummy_sp(:x);
print :x;
And the output:
PL/SQL procedure successfully completed.

I am working on a system where Oracle 11g is the back end database.
I have very limited permissions on the database and as such all I can do is call procedures that reside in packages.
Gerally, these procedure return their result set via an OUT parameter of type sys_refcursor.
I can call them fine in C# and get data from the cursor via the C# OracleDataset type.
Here is my question.
I want to be able to run these procedures and see the results via SQL Developer.
I can execute the procedure fine, but seeing the contents of the sys_refcursor OUT parameter is boggling me.
I've done some gooling and people ar saying about creating type and other solutions I simply do not have the permissions to persue.
So, how can I possibly see the result set contained in a sys_refcursor?
So say I have a procedure with this signature....
procedure an_oracle_Proc(p_ref IN varchar2,
p_result_set OUT sys_refcursor);
I call it like this....
DECLARE
l_ref VARCHAR2(10);
l_result_set sys_refcursor;
BEGIN
oracle_pkg.an_oracle_Proc(p_ref => l_ref,
p_result_set => l_result_set);
--How to select from l_result_set with limited permissions
END
How can I look at the contents of l_result_Set?
This is repeating the answer I linked to before really but specifically for your code:
VARIABLE result_set refcursor;
DECLARE
l_ref VARCHAR2(10);
BEGIN
l_ref := 'whatever';
oracle_pkg.an_oracle_Proc(p_ref => l_ref,
p_result_set => :result_set);
END;
/
PRINT result_set
... and run all of that as a script from an SQL Worksheet. The contents of the ref cursor will be shown in the script output window.
Thought I'd have another look and found this - amazing what stepping away from the computer can do. ;)
I just have to select the appropriate variable on the left pane.

Still - it would be nice to write my own SQL to do this rather than using the execute window.
Sys_refcursor form an anonymous block is bit tricky. Use the sql-developer, explore the package or procedure , right click and execute the procedure/package.
Sql-developer will open an input/output UI where you can key in values. And you can see the output on the same UI as well. Let me know if you need more details. I was actually debugging the same a couple of weeks back successfully.
I'm having some troubles executing oracle stored procedure from package.
I've intalled PL/SQL developer on local machine, and when I try to test procedure I get generated code like this:
begin
-- Call the procedure
owner.mypackage.getallrequests(res => :res,
id=> :id);
end;
But I can't modify this query to return me data. Would really appreciate help.
Assuming you've got to this point by right-clicking on the procedure in the object explorer and choosing 'test', you'll have a Test Window with the anonymous PL/SQL block you showed. You haven't said, but I assume id is an in variable, and res is the out cursor variable. In the variable section in the bottom half of the window, type in the ID value you're searching for, then execute it (clicking the gear, or hitting F8).
Nothing obvious will change if those are the only variables; non-cursor out or in out variables would be highlighted in yellow if their values had changed, but the cursor is not, and in variables by definition won't have changed.
At the far right of the res cursor variable in the bottom of the test window, there's a small button with ... in it, which the help pages refer to as the 'cell button'. Click that, and a new window will open showing the cursor result set.

Issue: Want to output a procedure OUT cursor into the SQLDeveloper SQLWosksheet.
Anyone know how to use the Oracle "Select * from Table( PipelinedFunction( Param ) ) " to check procedure code output cursors?
I am using Crsytal Reports off of an Oracle stored procedure. Crystal requires that a procedure return a cursor, which it fetchs and reads.
The procedure code I have is currently working, but I want to find the easiest way to view the effects of changes to the procedure code. I have SQLDeveloper available, and I'm doing my creation and sql testing in that. I would like to get a quick result visible in the SQL Developer Query Result window ("SQL Worksheet").
Is there a (simple) way to use a Function to read the cursor from the procedure? (and pipe that out to the Table function?)
Convoluted, I know, but I deal best when I can just see the results of code changes. If I can view the record results directly, it will speed up development of the report.
I know of the Table function and a little about pipelining in Oracle. I know a little about cursors in general and sys_refcursor. I know diddly about types and why I need them. (Isn't sys_regCursor supposed to get us away from that?)
The current procedure does an adequate but ungraceful series of queries, inserts to global temp tables (GTT), joins from GTT and original tables, more inserts, and more self-joins and then SELECTS the results into the OUT cursor. I might be able to do better relying on just cursors and such, but the current method is good enough to get results to the report.
I think I can handle SQL pretty well (for our purposes), but I am not an Oracle-specific developer... but I need help.
Anybody run across this? The whole idea was to speed my development for the procedure code, but I've spent a couple of days looking for a way to just get at the output... not what I had in mind.
Update:
I have tried some hare-brained schemes based on slivers that I've seen on the web... such as
Create or replace FUNCTION GET_BACKPLANE (
Node VARCHAR2 ) RETURN SYS_REFCURSOR
AS
RESULTS SYS_REFCURSOR;
BEGIN
Open Results for
Select Backplane(Results, Node) from Dual ;
... etc.
and
Create or replace Function GET_BACKPLANE (
NODE VARCHAR2 ) RETURN My_Table_Stru%ROWTYPE PIPELINED
AS
BEGIN ...
I don't think that Oracle is even considering letting me re-reference the output cursor from the procedure ("Results" is a sys_refcursor that holds the results of the last SELECT in the procedure). I don't know how to define it, open it, and reference it from the procedure.
I never got to the place where I could try
SELECT * FROM TABLE(GET_BACKPLANE( ... etc )
Sorry for any typos and bad Oracle Grammar... it's been a long several days.
SQL Developer allows us to use SQL*Plus commands in the Worksheet. So all you need to do is define a variable to hold the output of the ref cursor.
I may have misinterpreted the actual code you want to run but I'm assuming your actual program is a procedure Backplane(Results, Node) where results is an OUT parameter of datatype sys_refcursor and node is some input parameter.
var rc refcursor
exec Backplane(results=>:rc, Node=>42)
print rc
The output of the print statement is written to the Script Output pane.
Note that the use of SQL*Plus commands means we have to use the Run Script option F5 rather than execute statement.
Thanks for the help. In the end, I wound up brute-force-ing it...
Step by step:
Make a query, test a query,
create a global temp table from the structure,
add code to make another query off of that GTT, test the query,
create a global temp table from the structure,
etc.
In the end, I wound up running (anonymous block) scripts and checking the GTT contents at every stage.
The last part was to use the same last query from the original procedure, stuffing everything into the Cursor that crystal likes...
tomorrow, I test that.
But, I'll just force it through for the next procedure, and get it done in a day and a half instead of 2+ weeks (embarrassed).
Thanks,
Marc
