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.

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

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
where job_id = i_job_id;
RETURN v_Min_sal;
end get_minimum_salary;

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!Would you like to try this:

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! -

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

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.

AddEventListener and Function with Parameters
Hello guys
I got this situation
nameTxt.addEventListener(FocusEvent.FOCUS_IN,formTextHandler);
private function formTextHandler(text:String):void{
where i want to send some additional information too
so how could i do that?
Thankshi,
it seems like you will need to extend your text Component and Event class as well. Its not clear from your code that what component you are referring to . so generally you will extend your required component .
you will need to addEvent Listener
FocusEvent.FOCUS_IN
in your custom extended component and in the handler of that focusEvent you will dispatch your new custom event with the parameters from this FocusEvent you received and as well as new parameters that are also required by your new extended Event.
Method of extending events is straight forward. e.g this a sample for extending Events you will need to modify it with the paramaters you require in your event .
package
import flash.events.Event;
public class AccountEvent extends Event
public var accountObj:Object
public static var NewAccount:String='newAccount'
public function AccountEvent(type:String,newAccount:Object)
super(type)
this.accountObj=newAccount
and here is the code how to use this event
package
import flash.events.Event;
import flash.events.FocusEvent;
import AccountEvent
import mx.controls.TextInput
public class customText extends TextInput
public function customText()
super();
addEventListener(FocusEvent.FOCUS_IN,onFocus)
private function onFocus(e:FocusEvent):void{
dispatchEvent(new AccountEvent(paramaters.....///here you will add your custom paramerters and
//you will catch this event in your main application rather then catching the focus in event -
Crystal Reports from R/3 function with parameters
I can create reports from functions that doesn't require parameters, but for one function, the R/3 admin created the function that needs parameters (start and end date) to return records in that range. Does anyone know how to supply the parameter? I tried to select records by start and end date, but didn't work.
thanks
JennyHi Ingo:
Thank you for replying. It seems I have created the report correctly, but the function is not properly configured. So I'm forwarding the issue back to our R/3 admin.

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.
RajeshRajesh,
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.

How to use Count with Date Parameters
Hello,
I am having issues using the Count() function in conjunction with date parameters.
This is a Siebel report and in my report I have 2 date parameters(From Date, To Date). In a nutshell I am basically trying to count Opportunities that has a start date within the given date period. However I don't see a reasonable way to put my date parameters within the Count() function. The reason being is that I need to have a huge chunk of code to convert the dates into a common format that can be compared, and it won't even fit within the code block in my rtf template. I am not even sure how to put multiple conditional statements inside a Count() function since all the examples I have seen are very simple.
Anyone have a suggestion on how to use Count() with date parameters?
Thanks.Any chance you can get the date formats in the correct format from siebel?
I don't know Siebel - so I can't help you with that. If you get the correct format it is just
<?count(row[(FromDate>=date) and (date<=ToDate))?>
Otherwise the approach would probably need to use string function to get year/monthd/day from the date
and store it into a varialbe and compare later the same way
<?variable@incontext:from; ....?>
<?variable@incontext:to; ...?>
<?count(row[($from>=date) and (date<=$to))?>
Potentially you can use the date functions such as xdofx:to_date to do the conversion
[http://download.oracle.com/docs/cd/E12844_01/doc/bip.1013/e12187/T421739T481158.htm]
But I am not sure if they are available in your siebel implementation.
Hope that helps -
How to call stored procedure with multiple parameters in an HTML expression
Hi, Guys:
Can you show me an example to call stored procedure with multiple parameters in an HTML expression? I need to rewrite a procedure to display multiple pictures of one person stored in database by clicking button.
The orginal HTML expression is :
<img src="#OWNER#.dl_sor_image?p_offender_id=#OFFENDER_ID#" width="75" height="75">which calls a procedure as:
procedure dl_sor_image (p_offender_id IN NUMBER)now I rewrite it as:
PROCEDURE Sor_Display_Current_Image(p_n_Offender_id IN NUMBER, p_n_image_Count in number)could anyone tell me the format for the html expression to pass multiple parameters?
Thanks a lot.
SamHi:
Thanks for your help! Your question is what I am trying hard now. Current procedure can only display one picture per person, however, I am supposed to write a new procedure which displays multiple pictures for one person. When user click a button on report, APEX should call this procedure and returns next picture of the same person. The table is SOR_image. However, I rewrite the HTML expression as follows to test to display the second image.
<img src="#OWNER#.Sor_Display_Current_Image?p_n_Offender_id=#OFFENDER_ID#&p_n_image_Count=2" width="75" height="75"> The procedure code is complied OK as follows:
create or replace
PROCEDURE Sor_Display_Current_Image(p_n_Offender_id IN NUMBER, p_n_image_Count in number) AS
v_mime_type VARCHAR2(48);
v_length NUMBER;
v_name VARCHAR2(2000);
v_image BLOB;
v_counter number:=0;
cursor cur_All_Images_of_Offender is
SELECT 'IMAGE/JPEG' mime_type, dbms_lob.getlength(image) as image_length, image
FROM sor_image
WHERE offender_id = p_n_Offender_id;
rec_Image_of_Offender cur_All_Images_of_Offender%ROWTYPE;
BEGIN
open cur_All_Images_of_Offender;
loop
fetch cur_All_Images_of_Offender into rec_Image_of_Offender;
v_counter:=v_counter+1;
if (v_counter=p_n_image_Count) then
owa_util.mime_header(nvl(rec_Image_of_Offender.mime_type, 'application/octet'), FALSE);
htp.p('Content-length: '||rec_Image_of_Offender.image_length);
owa_util.http_header_close;
wpg_docload.download_file (rec_Image_of_Offender.image);
end if;
exit when ((cur_All_Images_of_Offender%NOTFOUND) or (v_counter>=p_n_image_Count));
end loop;
close cur_All_Images_of_Offender;
END Sor_Display_Current_Image; The procedure just open a cursor to fetch the images belong to the same person, and use wpg_docload.download_file function to display the image specified. But it never works. It is strange because even I use exactly same code as before but change procedure name, Oracle APEX cannot display an image. Is this due to anything such as make file configuration in APEX?
Thanks
Sam
