Custom sequences or functions with default parameters

Hello!
Using the Stimulus Profile Editor, I am finding that using a sequence within a sequence to be cumbersome. This is because it requires you to declare in the main sequence, every parameter that the sub-sequence will use.
I would like to have a 'configure' sequence whose parameters are all default and do not need to be declared or passed through by every sequence that calls it. Right now, if I change one argument of the 'configure' sequence I have to go to every sequence that references it, and update the parameters and the sequence call.
Essentially, I would just like an independent subfuction that has no inputs and returns a few outputs. If the profile editor is not capable of this, what would be my next best option?
Thanks!

Hello,
You can take advantage of the new features in NIVS 2014 to help against re-defining default values for your RT Sequences. Take a look at the documentation in 2014 which explains in more detail how you can use channel references in your sequences:
What's New in NI VeriStand 2014
http://zone.ni.com/reference/en-XX/help/372846H-01/veristand/whats_new/
Variables for Reading and Writing Channels in a Real-Time Sequence

Example 1a: Reading and Writing Channels Directly from a Real-Time Sequence
http://zone.ni.com/reference/en-XX/help/372846H-01/veristand/spe_tutorial_example1a/
By using channel references, you won't have to re-set default parameters. Let me know if you have any questions.

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.

Auto run report with default parameters in Viewer

Hi,
Can any one tell me if it's possible to automatically run reports in Disco Viewer with default parameter values?
For example, I have a worksheet with a parameter like 'Term like :Term Code' which has a default value of '%'.
When I open the sheet in Viewer I'm presented with the Confirmation screen with default parameter values displayed and then click OK to run report. Is there a way to skip the confirmation screen and just run the sheet with default values as soon as it's opened?
I tried using the 'Run Query Automatically' option in Query Governor preference but this results in Viewer opening the Edit Parameters screen instead of the confirmation screen.
What I'd ideally like to do is bypass both the Confirmation and Edit Parameters screen to automatically run the worksheet with default parameters as soon as it's selected.
Any thoughts appreciated,
Ien Hien

Hi,
Option 1
If the user is clicking on a URL for the report you could code the parameters directly into the URL thus, they are passed on startup. Section 13.5.2 Example 2 of the below URL provides an example:
http://download.oracle.com/docs/html/B13918_03/urlstart.htm#i1014363
Option 2 (Not Exactly what your looking for)
This would still require a user to click something but, if your passing a wildcard it should probably be considered,
If the parameter might be a wild card your better off making it an Optional Parameter which is now possible in Discoverer Plus 10.1.2. Thus, instead of passing an expensive % sign the condition will simply be ignored.
Hopefully this helps....

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

HI
I have made little bit changes in ur code. try this
create or replace function get_minimum_salary (i_job_id in varchar2)
return number
as
v_Min_sal jobs.salary%type=0;---- Variable declaration
begin
SELECT min_salary INTO v_ min_sal
FROM jobs

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.

Calling a stored procedure with default parameters

Dear all,
I am trying to call a stored procedure that has not all the parameters compulsory, and indeed, there are some I am not interested in. Therefore, I would like to call the stored procedure initializing only some of the parameters but if I miss some of them, I have an SQLException thrown. Is there any way to do that?
Thanks
Marie

Hi
One way to do it is ---
By using Default Parameters you can miss few parameters while calling a procedure.
=================================================================
As the example below shows, you can initialize IN parameters to default values. That way, you can pass different numbers of actual parameters to a subprogram, accepting or overriding the default values as you please.
Moreover, you can add new formal parameters without having to change every call to the subprogram.
PROCEDURE create_dept (
new_dname VARCHAR2 DEFAULT 'TEMP',
new_loc VARCHAR2 DEFAULT 'TEMP') IS
BEGIN
INSERT INTO dept
VALUES (deptno_seq.NEXTVAL, new_dname, new_loc);
END;
If an actual parameter is not passed, the default value of its corresponding formal parameter is used.
Consider the following calls to create_dept:
create_dept;
create_dept('MARKETING');
create_dept('MARKETING', 'NEW YORK');
The first call passes no actual parameters, so both default values are used.
The second call passes one actual parameter, so the default value for new_loc is used.
The third call passes two actual parameters, so neither default value is used.
Usually, you can use positional notation to override the default values of formal parameters.
However, you cannot skip a formal parameter by leaving out its actual parameter.
For example, the following call incorrectly associates the actual parameter 'NEW YORK' with the formal parameter new_dname:
create_dept('NEW YORK'); -- incorrect
You cannot solve the problem by leaving a placeholder for the actual parameter.
For example, the following call is illegal:
create_dept(, 'NEW YORK'); -- illegal
In such cases, you must use named notation, as follows:
create_dept(new_loc => 'NEW YORK');
===============================================================
For more details refer URL http://technet.oracle.com/doc/server.804/a58236/07_subs.htm#3651
Hope this helps

Curve fitting problem: simultaneously fitting two datasets to two different model functions with shared parameters

Hello! As stated above, I have the following problem: I have 2 sets (different systems) of measurement data (Voltages measured as functions of applied frequency). I would like to make curve fits with Levenber-Marquardt-method to both datasets (the datasets have the same x-values = frequencies), fitting the 2 datasets to their own separate model functions. However, the different model functions should have same values for the shared parameters (this prevents me from doing 2 totally separate curve fittings).
I have LabVIEW version 7.1, if anybody could help me with the problem, I would appreciate it very much. Thank you!

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?

Select from function with named parameters doesn't work

Hello,
I'm trying to execute the next sql statement:
SELECT mypack.getvalue(user_id => 231, status => 'closed') AS someAlias FROM DUAL;
I'm getting the next Error:
Error: ORA-00907: missing right parenthesis
But the next works fine:
SELECT mypack.getvalue(231,'closed') AS someAlias FROM DUAL;
What I'm doing wrong?
Is there a way to call a Function and return it's result as a single-row query?
Thanks for any suggestions.

Thanks for your answers.
Just want to explain what I want to accomplish:
I want to create PL/SQL statement which:
1) Calls Function in named notation way;
2) Returns a query which contains a single row - a Function result.
I know in Transact-SQL I can accomplish this the next way:
DECLARE @return_value INT
EXEC[myproc]
@id=2,
@status='ok',
@ret_param=@return_value OUTPUT
SELECT @return_value AS my_return_value
The last SELECT call returns a query with one row in it.
How can I do the same in Oracle?
Thanks a lot!

hi, i think you are only passing 6 parameters when you called out the procedure p_supperion_enrg. your procedure requires a 10 parameters.
if you do not want to include Trig,Etat,TypMod and IndRev you can simply put a null value.

Problems with procedures with DEFAULT parameters on 9i

The Forms builder shuts down when compiling a block that contains the reference to a stored procedure (packaged or not) that contains a defaulted parameter.
Sometimes it just terminates the connection (ORA-3113)
Is there a patch or a parameter setting that circumvents this failure?

Hi Hema,
There could be various things that explain this, but from your symptoms it looks like the engine is hung processing this report. This could be as simple as a PL/SQL trigger that is in an infinite loop. Anyway, a simple thing to do is to add TRACEFILE=filename&TRACEMODE=append&TRACEOPTS=TRACE_ALL onto your URL. This will create the specified file and dump information into it about what Reports is doing as it is processing your report. If it is hung in an infinite loop, you should be able to see how far it got when you kill it.
Also, you can see the status of the reports job queue by using the http://.../rwcgi60?showjobs command. If the report is executing forever, you'll see it sitting there in the job queue.
regards,
Stewart
