Oracle Function with out parameters

Hi, I'm trying to access a stored function on an oracle server with 2 out parameters, 2 in parameters and an out ref cursor.
PL/SQL looks like this
nStatusCode OUT INTEGER,
sStatusMsg OUT VARCHAR2,
sUsrNr IN VARCHAR2,
sPassword IN VARCHAR2,
crsReturn OUT pck_cursor.retRecordSet
I drag the function onto dataset designer and it successfully maps the results to the datatable, it maps datatypes for first out parameters to decimal and string.
the method genearated for fill by looks like (out decimal?,out string,string, string, out object)
problem is, everytime i try to call this function it gives me casting exceptions for the first 2 out parameters, for the decimal it's not specified in more detail. for the other one it says there was an exception casting from OracleString to string. If I change the PL/SQL function to leave the first 2 out parameters away it works fine. Do I manually need to change the TableAdapter definitions??

Hi,
I think I found the problem but not a good solution. It seems to be a problem with auto code generation for TableAdapters in the Dataset wizard. In the Parameter Definition for the Command I set DbType.Decimal and DbType.Sting for the SqlDbtype Property of the out params. The GetData and Fill Method is generated with Fill(out decimal? out1, out string out2). When I look in the generated code ith first sets the SqlDbtype as written but after this also the OracleDbtype to OracleDbType.Decimal and OracleDbType.Varchar2. The casting these types before returning the throws the exception. Any idea how to change this behavior?

Calling a procedure from Oracle Forms with OUT parameter

HI,
Can anyone tell me in detail how to call a procedure with OUT parameters from Oracle Forms 6i ?
Thanks in advance.

Hello,
Just provide the out parameter in the call:
Declare
amount number; -- OUT number argument populated by the procedure
Begin
-- call the X procedure --
x( amount ) ;
End;Francois

I can't execute oracle functions with c#. i'm using oracle 9i version.

i have a problem trying to execute an oracle function with c#.net. The Oracle version i'm using is Oracle 9i.
This is the function definition: (it's defined and working right because i have tryed it with SQLWorksheet)
CREATE OR REPLACE Function NRegistros return integer is
Numero integer(4);
begin
select count(*) into Numero from singles;
return Numero;
END NRegistros;
But with c#.Net i can't acces it because i get an error: "this is not a procedure or is not defined". And i think the code is right. In fact in the same code you can see that i'm using an stored procedure and i have not problems. But with the function i have problems. Is it possible that "OracleClient" can't work with Oracle9i functions??. This is the code:
OracleParameter Parametro = new OracleParameter("Name", OracleType.VarChar,10);
OracleParameter ParametroFuncion = new OracleParameter("Retorno", OracleType.Int32, 4);
Parametro.Direction = ParameterDirection.Output;
ParametroFuncion.Direction = ParameterDirection.ReturnValue;
OracleConnection Conexion = new OracleConnection("Data Source=DISCOS;User Id=SYSTEM;Password=a0000;");
Conexion.Open();
OracleCommand Todos = new OracleCommand();
OracleCommand Procedimiento = new OracleCommand();
OracleCommand Funcion = new OracleCommand();
Todos.Connection = Conexion;
Todos.CommandType = CommandType.Text;
Todos.CommandText="select * from singles";
Procedimiento.Connection = Conexion;
Procedimiento.CommandType = CommandType.StoredProcedure;
Procedimiento.CommandText = "Procedimiento";
Procedimiento.Parameters.Add(Parametro);
Funcion.Connection = Conexion;
Funcion.CommandType = CommandType.StoredProcedure;
Funcion.CommandText = "NRegistros";
OracleDataReader Lector = Todos.ExecuteReader();
BindingSource Discos = new BindingSource();
Discos.DataSource = Lector;

Procedimiento.ExecuteNonQuery();
Funcion.ExecuteNonQuery();
lblRegistroProcedimiento.Text = Procedimiento.Parameters["Name"].Value.ToString();
lblNregistros.Text=Funcion.Parameters["Retorno"].Value.ToString();
Conexion.Close();

Question about function with in parameters

Hello,
I have a question about functions with in-parameters. In the HR schema, I need to get the minimum salary of the job_id that is mentioned as an in-parameter.
this is what I am thinking but I dont know if it's correct or not or what should I do next!
create or replace function get_minimum_salary (i_job_id in varchar2)
return number
as
begin
SELECT min_salary INTO min_sal
FROM jobs
where job_id = get_minimum_salary(xy);
RETURN i_job_id;
end get_minimum_salary;
thanks in advance
EDIT
Thanks for your help all.
Is it possible to add that if the i_job_id which is the in type parameter does not have a minimum salary then use the following function to register an error:
create or replace procedure insert_error (i_error_code in number,
i_error_message in varchar2)
as
begin
insert into error_table (error_user, error_date, error_code, error_message)
values (user,sysdate,i_error_code,i_error_message);
end insert_error;
This function is basically to say that an error has occured and to register that error, at the same time I need to print out the error using the dbms_out.put_line.
Any ideas of how to do that?
Thanks again

Using a StoredProcedure with OUT parameters in CrystalReports

Hi All,
I am creating a report using CrystalReport Designer 2008.I have a StoredProcedure which takes 2 input parameters,2 output parameters and a cursor.I am not able to add this SP directly using the DatabaseExpert. if I use
'call SP1(input1,input2,input3,input4,@output1,@output2)' from AddCommand option then it gets added as a Command but the tree under Command does not expand and it does not allow me to use the output parameters in my reports.
Hence,can anyone please help me here such that how should I use this SP with out parameters in my CrystalReports.Also note that I am able to use StoredProcedure with only input parameters,with input parameters and cursor in my CrystalReports.Should I do something extra to add this StoredProcedure in my CrystalReports?
Any help for this issue would be highly appreciated.
Regards.
Ajit

Ajit,
If you are using a Command, you execute a SP in CR with the same syntax that you would in the databases native environment.The only difference is that you'll need to add CR parameters so that the inputs can be added to the SP's input parameters.
So, using your example... 'call SP1({?input1}, {?input2}, {?input3} , {?input4}, output1, output2)'
I'm not familiar with this particular syntax but hopefully you get the idea.
If you want to hard code the input parameters (and not have them prompt in CR), just hard code them in the command.
HTH,
Jason

Function with incomplete parameters

I create a function with many parameters
and I call this function through my application
but when I call function I must declare all parameter inside this function like
ddd("a","b",0,0,0,0,0,0,0)
is there a method let function set a default value for parameter if code didn't declare it

You can send just few first parameters and the rest will be passed as false. If you need to pass, say, first and 7th parameter, then you put 6 commas between values, as there is no named parameters in VFP and all parameters are passed by position.

Do you have the Toad Debugger? Thats the extra cost option which you get for free in OracleSqlDeveloper.
If you have the ToadDebugger, Read the Manual

How to call a Stored Function with OUT parameter of %rowType from Java

Hi everyone,
I'm getting crazy trying to make this work.
I have a function (not developed by me) in Oracle 10g declared in this way:
type tab_RLSSP is table of TB_RLSSP_STOSTPRPAR_CL%ROWTYPE index by binary_integer;
FUNCTION DBF_PERL_LISTA_PRATICHE (
p_id_va IN NUMBER,
p_seq_partita IN NUMBER,
p_trattamento IN CHAR,
lrec_RLSSP OUT tab_RLSSP ) RETURN NUMBER;
And here is the code snipplet of my java method:
sql="{? = call "+SCHEMA+PACKAGE+"."+FUNCTION_LIST+"(?,?,?,?)}";
cs=connection.prepareCall(sql);
cs.registerOutParameter(1, OracleTypes.NUMBER);
cs.setLong(2,idVATitolare);
cs.setLong(3,seqPartita);
cs.setString(4,trattamento);// Caso Decesso
cs.registerOutParameter(5, OracleTypes.OTHER);
cs.executeQuery();
result = (ResultSet) cs.getObject(5);
if (result.next())
listaPratiche.add(readPraticaPartita(result));
The result (exception thrown at executeQuery with statement generated as
SQL : {? = call PEDBA.DBK_PERL_RATEI_SUPPLETIVI.DBF_PERL_LISTA_PRATICHE(?,?,?,?)}:
java.sql.SQLException: ORA-06550: line 1, column 13:
PLS-00306: wrong number or types of arguments in call to 'DBF_PERL_LISTA_PRATICHE'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
Changing to :
sql="{call ? := "+SCHEMA+PACKAGE+"."+FUNCTION_LISTA+"(?,?,?,?)}";
leading to
SQL : {call ? := call PEDBA.DBK_PERL_RATEI_SUPPLETIVI.DBF_PERL_LISTA_PRATICHE(?,?,?,?)}
don't change anything.
What's wrong? Any suggestion?

>
Taking for granted that it works, I wonder what's different, probably the output is defined as Cursor...

You mean because of this line?
cs.registerOutParameter(5,OracleTypes.CURSOR);You can either use a cursor or use a function that returns a SQL type instead of the PL/SQL type.
Here is sample code using a cursor
CREATE OR REPLACE TYPE SCOTT.local_type IS OBJECT (
    empno   NUMBER(4),
    ename   VARCHAR2(10));
CREATE OR REPLACE TYPE SCOTT.local_tab_type IS TABLE OF local_type;

         END LOOP;
         -- Put the modified records back into the ref cursor for output.
         OPEN p_ref_cur_out FOR
         SELECT * from TABLE(l_recs);

Procedure with OUT Parameters - Creating A Report

I have the following procedure that is used in our internal (non-APEX) apps:
PROCEDURE SelIssueActivityPublic (
                                            p_results           OUT     SYS_REFCURSOR,
                                            p_IssueID                    IN     ems.issue.issue_id%TYPE,
                                            p_TransactionID         OUT VARCHAR2
             ) The body of the procedure does a bunch of processing, and inserts data into a staging table. The cursor OUT parameter then returns a SELECT statement from the staging table. Since it's possible for this procedure to be hit multiple times (multiple users), the transaction ID is used to match the data in the staging table to the correct request. The procedure then deletes the data from the staging table. (I'll post it if necessary, but it's quite long, and since it's used in other applications successfully, I don't believe it's relevant to my issue.)
I have been asked to create an APEX report of the data generated by the procedure. I've never used a procedure with an OUT parameter to set up a report. I was hoping to assign the transaction ID to a hidden variable on page load, and then using it to poplulate the report. I'm not interested in the cursor OUT parameter, I've written my own SELECT statement to grab data from the staging table.
I tried to create a page computation that did this - item :H_P19_TRANSID, Before Header, computation = EMS.EMS_READER.SelIssueActivityPublic(:H_P19_CURSOR, 454551, :H_P19_TRANSID) [454551 is a test issue id], but I get the following error: ORA-06550: line 1, column 43: PLS-00222: no function with name 'SELISSUEACTIVITYPUBLIC' exists in this scope ORA-06550: line 1, column 7: PL/SQL: Statement ignored flowComp=H_P19_TRANSID
Error ERR-1030 Error executing computation expression. It seems to be thinking that SelIssueActivityPublic is a function, and I'm not sure why.
Basically I need to know how to use this existing procedure to set up my report. Once I can get the transaction ID into a page item, I'll be set.

I never got a chance to finish this report, as I was shuffled to something else with a higher priority. Now that I'm coming back to it, I still have a few issues.
I created a new function that does all the processing (inserting into the staging table etc.), and returns the transaction id. I then tried to set up a page computation on a hidden item to run this function and store the transaction id.
In the computation, if I put
reader.SelIssueActivityPubnocursor(:H_P19_ISSUEID); as the computation, I get ORA-06503: PL/SQL: Function returned without value flowComp=H_P19_TRANSACTIONID as an error. If I put return return reader.SelIssueActivityPubnocursor(:H_P19_ISSUEID); as the computation, I get ORA-06550: line 1, column 50: PLS-00103: Encountered the symbol "EMS" when expecting one of the following: . ( * @ % & = - + ; < / > at in is mod remainder not rem <> or != or ~= >= <= <> and or like like2 like4 likec between || multiset member submultiset The symbol "." was substituted for "EMS" to continue. flowComp=H_P19_TRANSACTIONID as the error. Can someone tell me what's going wrong?

Executing procedures with OUT parameters using Named notation

I have a procedure with two out parameters (p_errortext and p_returncode) and i want to execute this proc in SQL*plus using named notation(using association operator ' => '). For position based execution i usually declare variables to hold the OUT parameter's value. But how can i do this while executing using named notation (using => )
begin
     packagename.generate_ref_record(p_userid => 'THELMA',
                                  p_ref_code       => '9A',
