Executing Procedures with an ODBC Passthrough query

Hi all,
Our current environment is oracle 8.1.7 db with an MS Access front end.
We are currently working on migrating the backend to 9.2.0.4, however testing has shown that sql passthrough statements that call stored procedures on the database now throw an ODBC error.
Has anyone else encountered this? and what was your solution.
P.S. budget restrictions preclude the obvious prefered solution - the front end will not change.

I recall seeing some documents in Microsoft's Knowledge Base back when 9i was new that said that things like ODBC and OLEDB were not going to support connectivity to Oracle 9i. For 9i .NET would have to be used instead. I don't know if this is still true, but the MS KB should be a good place for you to look.

Calling a Stored Procedure with output parameters from Query Templates

This is same problem which Shalaka Khandekar logged earlier. This new thread gives the complete description about our problem. Please go through this problem and suggest us a feasible solution.
We encountered a problem while calling a stored procedure from MII Query Template as follows-
1. Stored Procedure is defined in a package. Procedure takes the below inputs and outputs.
a) Input1 - CLOB
b) Input2 - CLOB
c) Input3 - CLOB
d) Output1 - CLOB
e) Output2 - CLOB
f) Output3 - Varchar2
2. There are two ways to get the output back.
a) Using a Stored Procedure by declaring necessary OUT parameters.
b) Using a Function which returns a single value.
3. Consider we are using method 2-a. To call a Stored Procedure with OUT parameters from the Query Template we need to declare variables of
corresponding types and pass them to the Stored Procedure along with the necessary input parameters.
4. This method is not a solution to get output because we cannot declare variables of some type(CLOB, Varchar2) in Query Template.
5. Even though we are successful (step 4) in declaring the OUT variables in Query Template and passed it successfully to the procedure, but our procedure contains outputs which are of type CLOB. It means we are going to get data which is more than VARCHAR2 length which query template cannot return(Limit is 32767
characters)
6. So the method 2-a is ruled out.
7. Now consider method 2-b. Function returns only one value, but we have 3 different OUT values. Assume that we have appended them using a separator. This value is going to be more than 32767 characters which is again a problem with the query template(refer to point 5). So option 2-b is also ruled out.
Apart from above mentioned methods there is a work around. It is to create a temporary table in the database with above 3 OUT parameters along with a session specific column. We insert the output which we got from the procedure to the temporary table and use it further. As soon the usage of the data is completed we delete the current session specific data. So indirectly we call the table as a Session Table. This solution increases unnecessary load on the database.
Thanks in Advance.

Rajesh,
please check if this following proposal could serve you.
Define the Query with mode FixedQueryWithOutput. In the package define a ref cursor as IN OUT parameter. To get your 3 values back, open the cursor in your procedure like "Select val1, val2, val3 from dual". Then the values should get into your query.
Here is an example how this could be defined.
Package:
type return_cur IS ref CURSOR;
Procedure:
PROCEDURE myProc(myReturnCur IN OUT return_cur) ...
OPEN myReturnCur FOR SELECT val1, val2, val3 FROM dual;
Query:
DECLARE
MYRETURNCUR myPackage.return_cur;
BEGIN
myPackage.myProc(
MYRETURNCUR => ?
END;
Good luck.

Reg:execute procedure with in out parameters

hi,
what is the code to execute a procedure with in out parameters.can anyone give me an example

thanks for the reply.
i am very much new to oracle database.i need this code to put in one of my informatica mapping.
so can you just elaborate what does 'karthick' mean?is it the name of the procedure.No, karthick is the value of the variable that is being passed into the procedure called "P" in karthicks example, then if that procedure changes the value inside, the variable will have that new value passed back out of the procedure to it.
PROCEDURE prc_mv (name VARCHAR2)
IS
BEGIN
dbms_mview.refresh (mv_name);
END prc_mv;
PROCEDURE refresh (response IN OUT NUMBER)
IS
BEGIN
dbms_mview.refresh('mv1','C');
dbms_mview.refresh('mv2','C');
response := 1;
EXCEPTION
WHEN OTHERS
THEN
response := 0;
END refresh;
can you give the code for this procedure.Yes.
DECLARE
v_response NUMBER;
BEGIN
refresh(v_response);
END;Though your code is awful. There's no point in having the response parameter as an IN OUT if you're not going to pass IN a value and use that in the code anywhere. In your case it only needs to be an OUT parameter because you're just passing back OUT a value. You are also masking any exceptions that happen by using a WHEN OTHERS clause.
Better code would be something like...
FUNCTION refresh (mv_name) RETURN NUMBER IS
v_response NUMBER := 0; -- default response value
e_mv_not_exist EXCEPTION; -- exception variable
PRAGMA EXCEPTION_INIT(e_mv_not_exist, -23401); -- connect exception name to internal oracle error number
BEGIN
dbms_mview.refresh(mv_name,'C');
v_response := 1;
EXCEPTION
WHEN e_mv_not_exist THEN -- handle specific expected exception
    -- if the materialized view does not exist, handle it gracefully as we don't want to stop
    response := 0;
END refresh;
declare
v_response NUMBER;
begin
v_response := refresh('mv1');
if v_response = 0 then
    -- the materialized view did not exist
else
    -- the materialized view refreshed ok
end if;
end;where your exception handler explicity checks for expected exceptions such as :
ORA-23401: materialized view "SCOTT"."FRED" does not exist... and any other exceptions that you're not expecting will be raised for you to see.
It's also better as a function because you don't need to pass in a response value, you just want to get a response value back.
There's rarely a good need to use OUT or IN OUT parameters. (there's some cases, but it's not something to consider doing as part of your regular design)

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',

Problem Calling MaxDB stored procedure with output from MII Query template

Hi,
I am using Max DB Database studio to write stored procedure, I am calling stored procedure from MII Query using CALL statement.
Can anyone guide me how to pass output values of stored procedure.
Examlpe::
call ProcName('[Param.1]','[Param.2]','[Param.3]','[Param.4]','[Param.5]', :isSuccess, :Trace)
In the above line of code I am not able to get the output values of stored procedure that is isSuccess and Trace values in Query template when executed. But same thing I get when executed in Database studio.
How do I call with outputs for any stored procedure in MII.
Any help would be appriciated.
Thanks,
Padma

My call statement is like this
call RESULTDATA_INSERT('[Param.1]','[Param.2]','[Param.3]', :isSuccess, :Trace)
I am able to insert record in DB, But I am not getting output values in Query template.I have done this in Fixed Query, when I execute it throws me "Fatal error as Loaded content empty".
I tried giving select below call but it dont work.

Hi Luk,
if you work with reference personnel numbers you will also consider infotype 0031 for your procedure. There is a relationship (Q0000-RFPNR) between the infotypes 0000 and 0031.

Executing procedure with collection TYPE as IN param

Hi ,
I am using Oracle Version 10.2.0.4.0.
I have created a TYPE AE_SEQ_TAB1 IS TABLE OF number;
This is my SP header:
PROCEDURE test_data
ip_table_nm IN VARCHAR2,
ip_ae_seq_no IN      AE_SEQ_TAB1,
op_error_cd OUT VARCHAR2,
op_error_desc OUT VARCHAR2,
op_active_data OUT SYS_REFCURSOR
I want to pass multiple values to ip_ae_seq_no while testing this SP. So I am doing like.
DECLARE
REF_CUR SYS_REFCURSOR;
ERR     VARCHAR2(1000);
ERR1     VARCHAR2(1000);
ip_ae_seq_no ae_seq_tab1;
BEGIN
ip_ae_seq_no :=ae_seq_tab1(1,2,3);
test_data('CP_TBL',ip_ae_seq_no,ERR,ERR1,REF_CUR);
END;
This gives me the error with :
ORA-06550: line 8, column 1:
PLS-00306: wrong number or types of arguments in call to test_data
Whats the mistake I am doing in this?
Also can I check the count of elements from this table at run time something like
SELECT COUNT(1) INTO l_tab_type_cnt from TABLE(ip_ae_seq_no);

Executing Procedure with default parameters !!

hi want a small help ...
I have a
procedure p1(p1 in number default 2, p2 in number default 3)
begin
end;
When the procedure will be called without passing parameters it will execute with default parameters.
That time I want to dispay message saying
" AS paramters are not passed, procedure is being executed with foll. default parameters:
Param 1 = 2
Param 2 = 3 "
Now issue is how do I capture this condition that , the parameters are being passed and it is using default parameters ?
Thanks

The IF NOT NULL check for the parameters cannot be inside the same procedure becuase when you reach that statement, even though the parameter are not passed to this procedure, at that stage, the parameters will acquire the dfault values already assigned to them. So you never reach the else part of it.
That;s why i said, use third parameter and assign the value to this third parameter from the calling environment.
here is the short test case that might help you to understand better.

Execute procedure with WebRowSet

I want to execute stored procedures created in a sql 2000 database using webrowset.
I tried the following:
1. wrs.setCommand("proc1")
2. wrs.setCommang("exec proc1")
both of them gave me the following error:
java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]No rows affected.
I need to use the webrowset for xml
How can i then execute the procedures using webrowset??

Well, I couldn't find any way to execute stored procedures directly using WebRowSet. Instead I used a statement that queries a stored procedure and populated the resulting resultset with a webrowset, like this:
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("proc1");
WebRowSet xmlSet = new WebRowSetImpl
xmlSet.populate(rs);
This method works

Hi,
I was able to solve the problem.. My cursor was declared like this.
TYPE journal_def IS RECORD
          journal_sid                    NUMBER(10),
          journaltext                    CLOB,

TYPE journal_cursor                    IS REF CURSOR RETURN journal_def;
I used the journal_def type to fetch the records.
Here is how my final sql looked like.
DECLARE
P_PROJECT_SID NUMBER;
P_JOURNAL_CURSOR journal_cursor;
P_J_CURSOR journal_def;
BEGIN
P_PROJECT_SID := 11171;
-- Modify the code to initialize the variable

BEGIN
--open P_JOURNAL_CURSOR;
loop
fetch P_JOURNAL_CURSOR into P_J_CURSOR;
exit when P_JOURNAL_CURSOR%NOTFOUND;
DBMS_OUTPUT.put_line(P_J_CURSOR.journal_sid);
end loop;
--close P_JOURNAL_CURSOR;
END;
END;
This gave me results. Thanks a ton ALL for your help..... :)..

How to execute procedure with dynamic where condition.

Hi All,
I am facing a probelem
Issue :
I am having a parameter p_id in my procedure based on the value of this parameter i want to change the where condition.
How to do so?
Code:---------
create or replace procedure p_1
( p_id in emp_dummy.empno%type)
is
parameter_1 varchar2(2000);
v_sal number;
begin
if p_id = 1 then
parameter_1 := 'where empno = 1';
else
parameter_1 := 'where 1=1';
end if;
select salary into v_sal from emp_dummy||' '||parameter_1;
end;

Dynamic SQL is not the best of ideas, but if you must...
EXECUTE IMMEDIATE 'select salary from emp_dummy where empno=nvl(:x,empno)' into v_sal using p_id;Then if you pass in the p_id to the procedure it will select the salary for that employee and if null is passed in then it will select the salary for all employees. Now here's a problem because you are trying to return a single value and if you don't specify the employee then it will try and return multiple values from that select, so you probably want to do something like give the sum of the salaries...
EXECUTE IMMEDIATE 'select sum(salary) from emp_dummy where empno=nvl(:x,empno)' into v_sal using p_id;

Your reference is invalid:
WHERE TravelType = ST_GetTravelTypeID.TravelType;
This should not (cannot) refer to the name of the procedure - but simply to the variable in it. I.e.
WHERE TravelType = TravelType;
However, as you can see, the variable name is now the same as the column name.
One method around this is to use explicit scope reference. E.g.
SELECT
t.TravelTypeCode,
t.TravelTypeDesc
FROM ST_MS_TravelTypes t
WHERE t.TravelType = TravelType;I suggest that you consider this a standard for your PL/SQL programming. Always alias SQL tables in PL/SQL code and use explicit column references.
Another standard we use is to use underscore characters for columns - camel case is fine for variables in a programming language. This is not really acceptable for column names, as by default Oracle uses uppercase. Thus "TravelType" is valid as variable name, but invalid as a column name - it should be defined/written as "travel_type" or "TRAVEL_TYPE" instead.

Executing procedure for period

Hi all,
My need is to execute procedure with parameter date for period from 01.03.2011 till 31.03.2011.
One way is to type dates one per line:
EXEC schemename.pkg_name.procedure_name date '2011-03-01';
EXEC schemename.pkg_name.procedure_name date '2011-03-02';
EXEC schemename.pkg_name.procedure_name date '2011-03-30';
EXEC schemename.pkg_name.procedure_name date '2011-03-31';But how do I execute it using more simple code?

Hello
It kind of depends what you mean by simpler. If you want to avoid having 31 separate calls to the procedure listed on 31 lines, you can use a loop like so...
SQL> DECLARE
2
3      ldt_StartDate       DATE := TO_DATE('01/03/2011','dd/mm/yyyy');
4      ldt_EndDate         DATE := TO_DATE('31/03/2011','dd/mm/yyyy');
5
6 BEGIN
7
8      FOR lc_Dates IN (   SELECT
9                              ldt_StartDate + (rownum -1) dt
10                          FROM
11                              dual

Return code for EXECUTE PROCEDURE (native SQL)

Hi Experts,
I've seen in the Note 364707 that the field %_ERRCODE is no longer supported since WAS 6.10 for stored procedures like this:
EXEC SQL.
EXECUTE PROCEDURE proc [(parameter list)] %_ERRCODE INTO :rc
ENDEXEC.
So an Upgrade to WAS 7.00 gives this programms an error.
Has anybody an idea for an alternative?
Regards,
Stefan

Hello Peluka,
i have seen you have worked with 'execute procedure'.
I want to execute a procedure with two Parameters and one structure. Example:
EXECUTE PROCEDURE test.p_getdata ( in :i_ls_nr , in :vdatum , out :vtest ).
vtest has the simple structure with field lieferscheinnr (char25).
When i execute the procedure, i get the error <b>wrong number or types of arguments in call</b>.
Do you know, whether execute procedure with structures is not possible?
Thank you in advance.
