* EDIT6: * This is what ended up working for me (from accepted answer):
var ret1 number
var tran_cnt number
var msg_cnt number
var rc refcursor
exec :tran_cnt := 0
exec :msg_cnt := 123
exec get_account(Vret_val => :ret1, Vtran_count => :tran_cnt, Vmessage_count => :msg_cnt, Vaccount_id => 1, rc1 => :rc)
print :tran_cnt
print :msg_cnt
print :rc
The SQL Developer makes this super-hard / impossible?. I do not care if the utility is command-line-based; I just want to be able to run and view it quickly. It would be nice if it captured errors well as well. it would be nice to be able to log in gradually(interactively), as well as specifying everything at once (similar to how a typical ftp / sftp cmd-based client works).
My platform is Windows Server 2008 + Cygwin.
EDIT: Perhaps you would know how to script this using Python?
EDIT 2: In MSFT SQL server I can simply type this:
get_user 1;
then highlight it and hit F5, and I get:
login name
NULL Somename
printed to the output window. The Oracle SQL developer does not help with this at all. I am not sure how to pass in a 1, I am not sure how to see the actual rows/records that come back.
EDIT3: When I type just var rc refcursor;
and select it and run it, I get this error (GUI):
An error was encountered performing the requested operation:
ORA-00900: invalid SQL statement

I get an error:

Why does it say line 1, column 134? No line stretched that far ...
Not only is there a way to do this, there is more than one way to do this (which I concede is not very Pythonic, but then SQL*Developer is written in Java ).
I have a procedure with this signature: get_maxsal_by_dept( dno number, maxsal out number)
.
I highlight it in the SQL*Developer Object Navigator, invoke the right-click menu and chose Run. (I could use ctrl+F11.) This spawns a pop-up window with a test harness. (Note: If the stored procedure lives in a package, you'll need to right-click the package, not the icon below the package containing the procedure's name; you will then select the sproc from the package's "Target" list when the test harness appears.) In this example, the test harness will display the following:
DECLARE
DNO NUMBER;
MAXSAL NUMBER;
BEGIN
DNO := NULL;
GET_MAXSAL_BY_DEPT(
DNO => DNO,
MAXSAL => MAXSAL
);
DBMS_OUTPUT.PUT_LINE('MAXSAL = ' || MAXSAL);
END;
I set the variable DNO to 50 and press okay. In the Running - Log pane (bottom right-hand corner unless you've closed/moved/hidden it) I can see the following output:
Connecting to the database apc.
MAXSAL = 4500
Process exited.
Disconnecting from the database apc.
To be fair the runner is less friendly for functions which return a Ref Cursor, like this one: get_emps_by_dept (dno number) return sys_refcursor
.
DECLARE
DNO NUMBER;
v_Return sys_refcursor;
BEGIN
DNO := 50;
v_Return := GET_EMPS_BY_DEPT(
DNO => DNO
);
-- Modify the code to output the variable
-- DBMS_OUTPUT.PUT_LINE('v_Return = ' || v_Return);
END;
However, at least it offers the chance to save any changes to file, so we can retain our investment in tweaking the harness...
DECLARE
DNO NUMBER;
v_Return sys_refcursor;
v_rec emp%rowtype;
BEGIN
DNO := 50;
v_Return := GET_EMPS_BY_DEPT(
DNO => DNO
);
loop
fetch v_Return into v_rec;
exit when v_Return%notfound;
DBMS_OUTPUT.PUT_LINE('name = ' || v_rec.ename);
end loop;
END;
The output from the same location:
Connecting to the database apc.
name = TRICHLER
name = VERREYNNE
name = FEUERSTEIN
name = PODER
Process exited.
Disconnecting from the database apc.
Alternatively we can use the old SQLPLus commands in the SQLDeveloper worksheet:
var rc refcursor
exec :rc := get_emps_by_dept(30)
print rc
In that case the output appears in Script Output pane (default location is the tab to the right of the Results tab).
The very earliest versions of the IDE did not support much in the way of SQL*Plus. However, all of the above commands have been supported since 1.2.1. Refer to the matrix in the online documentation for more info.
"When I type just
var rc refcursor;
and select it and run it, I get this error (GUI):"
There is a feature - or a bug - in the way the worksheet interprets SQLPlus commands. It presumes SQLPlus commands are part of a script. So, if we enter a line of SQL*Plus, say var rc refcursor
and click Execute Statement
(or F9 ) the worksheet hurls ORA-900 because that is not an executable statement i.e. it's not SQL . What we need to do is click Run Script
(or F5 ), even for a single line of SQL*Plus.
"I am so close ... please help."
You program is a procedure with a signature of five mandatory parameters. You are getting an error because you are calling it as a function, and with just the one parameter:
exec :rc := get_account(1)
What you need is something like the following. I have used the named notation for clarity.
var ret1 number
var tran_cnt number
var msg_cnt number
var rc refcursor
exec :tran_cnt := 0
exec :msg_cnt := 123
exec get_account (Vret_val => :ret1,
Vtran_count => :tran_cnt,
Vmessage_count => :msg_cnt,
Vaccount_id => 1,
rc1 => :rc )
print tran_count
print rc
That is, you need a variable for each OUT or IN OUT parameter. IN parameters can be passed as literals. The first two EXEC statements assign values to a couple of the IN OUT parameters. The third EXEC calls the procedure. Procedures don't return a value (unlike functions) so we don't use an assignment syntax. Lastly this script displays the value of a couple of the variables mapped to OUT parameters.
