First of all my knowledge of Oracle is very limited.
I have inherited a large Delphi project using Oracle, it have been upgraded to Oracle Cloud. And now I have some problems calling a Stored procedure :
Lets start with the SP's (It is placed in a package )
PROCEDURE GetAccessObjects(AAccessObjects OUT CURSOR_TYPE);
Then the Delphi Code:
procedure TDBApi.GetAccessObjects(var ResultSet: TADOStoredProc);
var
SP: TDbStoredProc;
begin
SP := CreateStoredProc(SQLPackage + 'GetAccessObjects');
try
SP.MaxRecords := mrAll;
SP.Open;
ResultSet := SP;
except
SP.Free;
raise;
end;
end;
When executing the Delphi code I get the error
PLS-00306: wrong number or types of arguments in call to
'GETACCESSOBJECTS'
And calling the SP from SQL Developer (exec DDK.GetAccessObjects()) I get the same error.
I can read and understand the error message: Missing parameter. But what beats me is the fact that this code have been running for years. At least 5.
I have at least 10 SP's with this "problem" so its not a simple typo.
So in short how do I move on from here?
How do I call this SP?
Can I set some kind of global setting so I don't have to pass this parameter?

This is only my second time diagnosing a PL/SQL procedure. I need to test the code in the stored procedure, and I'm trying to call it in SQL Developer. I have run the error details report, and the code has no obvious bugs in it.
So now I am trying to run it through a test window so I can see if the output is correct. However I can't seem to get the right argument for the 3 parameter. Here are the parameters in the the procedure.
CREATE OR REPLACE PROCEDURE ADVANCE.WW_DEATHDATE_REPORT(begindate varchar2, enddatevarchar2, RC1 IN OUT du_refCUR_PKG.RC) AS
Here is the Code I am trying to use to call the procedure. What do I need to do to get it to run correct? I keep getting error messages saying I'm using a wrong value in the parameter.
BEGIN
ADVANCE.WW_DEATHDATE_REPORT('20100101','20150101',du_refcur_pkg);
END;
There are multiple ways to do this, one way is like the below,
DECLARE
du_refcur_pkg SYS_REFCURSOR;
BEGIN
OPEN du_refcur_pkg FOR SELECT ... ;
ADVANCE.WW_DEATHDATE_REPORT('20100101','20150101',du_refcur_pkg);
END;
Another way would be,
BEGIN
ADVANCE.WW_DEATHDATE_REPORT( '20100101','20150101', CURSOR (SELECT ... ) );
END;
I need a generalized method to get list of runtime parameters (values) when I call a procedure. I need something similar to the $$PLSQL_UNIT that returns the name of the running procedure.
(plsql Oracle 10g)
E.g. look at this sample procedure:
(it simply prints its own name and parameters )
CREATE OR REPLACE PROCEDURE MY_PROC(ow in varchar2, tn IN varchar2)
IS
BEGIN
dbms_output.put_line('proc_name: '||$$PLSQL_UNIT||' parameters: '|| ow||' '||tn );
EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE('ERRORE: ' ||SQLERRM);
END MY_PROC;
/
Running procedure produces the following output:
SQL>
1 BEGIN
2 IBAD_OWN.MY_PROC('first_par', 'second_par');
3 END;
4 /
proc_name: MY_PROC parameters: first_par second_par
PL/SQL procedure successfully completed.
I'm not satisfy because I can't copy and paste in all my procedures because I have to hard code each procedure to set their right parameter variables.
Thanks in advance for the help.
It isn't possible to dynamically retrieve the values of parameters passed to a procedure in Oracle PL/SQL. The language simply isn't designed to handle this kind of operation.
Incidentally, in a procedure that is located within a package, $$PLSQL_UNIT will only return the package's name. I find it's better to define a consistently-named constant within each procedure that contains the procedure's name.
When I wanted the same functionality as yours I didn't find any good built-in solution.
What I did is: wrote DB-level trigger which modifies original body of function/procedure/package.
This trigger adds immediatly after "begin" dynamically generated piece of code from "user_arguments".
Plus, after that I include into this trigger the code, that logs calls of procs when exception occures.
Plus, you can trace procs calls, and many more interisting things.
But this solution works fine only for preproduction because performance decreases dramatically.
PS. Sorry for my bad English.
I wrote a stored procedure in oracle to check weather given input file name exists in defined path. It is working fine. When i call this procedure in power-builder 12.0 i tested like this. First time i entered wrong file name it is works fine. Then i entered correct file name it is saying that Procedure has already been executed. How can i re-execute this procedure again. MY code to declare the procedure in package is
DECLARE PROC_FILE_EXISTS PROCEDURE FOR
HICSWIN_ORACLE.PACK_UPDATE_TSHML_HICSWIN20.PROC_CHECK_FILES_RELEVANCE
(
FILE_NAME => :as_file_name
) ;
EXECUTE PROC_FILE_EXISTS;
IF SQLCA.SqlCode < 0 THEN
MessageBox('eroor',SQLCA.SQLErrText)
MessageBox('Connection failed','An error occured while connecting to database, please contact your administrartor')
RETURN 0
end if
FYI i am using windows 7 with oracle 11g
You need to close the procedure call (in a way similar to a cursor use : Declare / Open / Fetch / Close):
close PROC_FILE_EXISTS;
Call it from a datastore. Create a new dw with a stored procedure source, and the string retrieval argument. PB includes all the appropriate cursor syntax automatically. Calling Oracle SPs may be more complex - I believe you have to return a ref cursor to call one from a dw...
This problem came up when trying out the Unit Testing capabilities of SQLDeveloper.
When running a test for a procedure that is created within my schema I am seeing an error however when the same procedure is run in one of the oracle supplied schemas it works without an issue.
SQL Developer generates the following calls:
1) This one doesn't work (error is shown below):
BEGIN
"IANC"."SIMPLE_PARAMETER"(P_X => 123);
END;
2) This one does:
BEGIN
"HR"."SIMPLE_PARAMETER"(P_X => 123);
END;
This is the procedure:
CREATE OR REPLACE PROCEDURE SIMPLE_PARAMETER
(
P_X IN NUMBER
)
IS
BEGIN
null;
END SIMPLE_PARAMETER;
The following is the output from SQLPLUS, where you can see when the procedure is run in my schema I see an error whilst when running the same procedure in another schema the procedure works as expected:
In case of need my I am using Oracle Enterprise Edition 11.2.0.1.0
Update
Screen shot showing procedure signatures
I should also mention that if I remove the schema name from the procedure call then the procedure runs and completes as expected.
Thanks in advance for any help received.
Are you sure that the SIMPLE_PARAMETER procedure in IANC is the same (or at least has the same signature) as the one in HR? What do you get from `DESCRIBE "IANC"."SIMPLE_PARAMETER".
(P.S. since your identifiers are all upper-case, you shouldn't need the double quotes at all.)
Added: Another possibility is that you have a package called IANC in the IANC schema, so Oracle is looking for a procedure in that package called SIMPLE_PARAMETER that does not exist. Example:
SQL> exec bigdecimaltest
PL/SQL procedure successfully completed.
SQL> exec dcosta.bigdecimaltest
PL/SQL procedure successfully completed.
SQL> create or replace package dcosta as
2 end;
3 /
Package created.
SQL> exec dcosta.bigdecimaltest
BEGIN dcosta.bigdecimaltest; END;
*
ERROR at line 1:
ORA-06550: line 1, column 14:
PLS-00302: component 'BIGDECIMALTEST' must be declared
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
This seems like buggy behavior -- if the attempt to resolve the name as package.member doesn't succeed, I think Oracle ought to then try it as schema.object, but it looks like once it has found a match on the package name it won't reconsider that.
I'm trying to call an Oracle stored procedure that accepts no input parameters. However, when running the procedure, I get an error back that states
PLS-00306: wrong number or types of arguments in call to 'MY_PROC'
To call the proc, I'm just entering the following text into TOra:
BEGIN
SCHEMA.MY_PROC();
END;
I've also tried (same error though)
EXEC SCHEMA.MY_PROC();
I'm familiar with MSSQL and I'm able to execute SP with no problem using SQL server, but I can't figure out how to do the same with Oracle. I can't view the actual code for the stored procedure, but from the limited documentation I have, it appears it accepts no input parameters and the return value is a ref cursor. I have a feeling that I need to pass in a ref cursor somehow, but everything I've tried in that regard has not worked.
I just want to view the results of the SP as if I had done a SELECT statement, that is, with the records populating the data grid in the results panel in the TOra interface.
It sounds like the procedure does have an OUT parameter (in Oracle, procedures do not return anything but can have OUT and IN OUT parameters, functions return something). So you would have to pass in a variable for that OUT parameter. Something like
DECLARE
l_results SYS_REFCURSOR;
BEGIN
schema.my_proc( l_results );
END;
should successfully call the procedure. But then you want your GUI to display the results from that cursor. That, unfortunately, gets a little more complicated because now you're talking about a GUI-specific issue.
I don't use TOra, so I don't know what you need to do in TOra to get the cursor to display. In SQL*Plus (or SQL Developer, Oracle's free GUI), you could do something like
create or replace procedure my_proc( p_rc OUT SYS_REFCURSOR )
as
begin
open p_rc
for select 1 col1
from dual;
end;
/
variable rc refcursor;
exec my_proc( :rc );
print rc;
This creates a stored procedure with an OUT parameter that is a cursor, declares a host variable that can be passed in, and then prints the results.
