Labview control caption passed as parameter name

Hi,
Why is the Caption of a Labview control, when the control is assigned as a terminal on the VI connector, passed to Teststand as the parameter name ?
I would have expected the Label of the control to be the parameter name passed to Teststand.
In the past I've used the control's Caption to locally modify the front panel text, and the Label is used to represent the data's\variables name.
regards,
Gary.

Hi Gary,
My name is Kevin and I am an Application Engineer at NIUK.
The original idea was to show the caption (if not empty) of a control instead of the label in case the user decides to localized the control by modifying the caption which we can dynamically change. The LV adapter stores both the caption and the label. The caption is only shown if it is not empty.
Changing the behavior to always show labels will not affect compatibility since we already store them. Most of the time, the label and the caption are the same and if they are not the same I don't see a problem with just showing the caption. I have never seen a VI that shows both the caption and the label at the same time and if the caption is different that is what it is shown instead of the label.

Control's label/caption passed from calling vi

I would like a way to pass the control name and data to a subvi so the subvi control names are overwritten. I want the subvi to take each name from the calling program and make a text header using the calling names (not the subvi control names). The files I've attached aren't exactly what I want, but may give the general idea of what I want to accomplish. I would like to NOT pass anything other than the control into the subvi (as I have currently have it, if possible). If this question is not clear, please let me know.
-Thanks in advance.

You cannot change the label of a control during runtime. This is why LabVIEW incorporates Captions.
I will take a look at your VIs later (when I turn on my workstation) and look at your implementation to see if I can offer any further advice. I used a method similar to this to pass data to indicators and sent a string to the caption to adjust the display to indicate the "label" of the value.

Passing the database name as a PL/SQL procedure parameter

How do I pass the name of the database as a parameter to a procedure?
If dbs is the variable name to which I pass the database name as shown in the example,
CREATE OR REPLACE PROCEDURE Extract_gl_acct_Tbl(dbs varchar2)
and I use dbs in the code as follows,
SELECT ACCOUNT,
SETID
FROM SYSADM.PS_GL_ACCOUNT_TBL@dbs
It gives me an error saying 'ORA-04054: database link DBS does not exist'.

You will need to use dynamic SQL to handle this:
create or replace ...
is
type rc is ref cursor;
v_rc rc;
begin
open v_rc for 'select ... from sysadm.ps_gl_account_tbl@' || dbs;
fetch v_rc into ... -- some variables
-- if multiple rows, you'll need to do the fetch in a loop and exit when v_rc%notfound.
close v_rc;
end;

How to run a webdynpro multiple times by passing different parameters each time and save webpages with parameter name?

Hi Experts,
I am a BW consultant and new to webdynpro. Not sure how to run RSO_METADATA_REPOSITORY multiple times and by passing different parameter values each time(either taken from an a standard BW table or user provided - anything is fine) and build web pages with parameter name. Need help with direction on where to start.
Let me step back and explain my requirement:
In BW we have an object called transformation.
One way of generating documentation for transformation is highlight transformation and press F1. Then its documentation will be opened as a local web page.
I need these web pages for all transformations. This is my requirment.
I came to know that RSO_METADATA_REPOSITORY is beeing used to generate this web page.
The web link is something like below:
http://ubw05.xxx.com:8005/SAP/BW/DOC/METADATA/?page=BW_O_D&SystemID=BWPCLNT100&ClassID=TRFN&ID=0KHR6J65AIIUTCJZEC093K6XDFV909PB&objectVersion=A&sap-language=EN&sap-client=100
When i run this link seperately(not by selecting transformation and pressing F1) i need to enter login credentials to BW system.
My challenges is how do i pass login credentials and multiple transformation IDs to generate multipe web pages with each page named by transformation ID?
WHere to start? First of all is RSO_METADATA_REPOSITORY Webdynpro JAVA or webdynpro ABAP or can i use anything?
Since it is beeing opened as local webpages i assume it is webdynpro JAVa is that correct?
Thanks,

Passing Inner class name as parameter

Hi,
How i can pass inner class name as parameter which is used to create object of inner class in the receiving method (class.formane(className))
Hope somebody can help me.
Thanks in advance.
Prem

No, because an inner class can never have a constructor that doesn't take any arguments.
Without going through reflection, you always need an instance of the outer class to instantiate the inner class. Internally this instance is passed as a parameter to the inner class's constructor. So to create an instance of an inner class through reflection you need to get the appropriate constructor and call its newInstance method. Here's a complete example:import java.lang.reflect.Constructor;
class Outer {
    class Inner {
    public static void main(String[] args) throws Exception{
        Class c = Class.forName("Outer$Inner");
        Constructor cnstrctr = c.getDeclaredConstructor(new Class[] {Outer.class});
        Outer o = new Outer();
        Inner i = (Inner) cnstrctr.newInstance(new Object[]{o});
        System.out.println(i);
}

File name and path should be passed as parameter

hi all,
i am writing a set of statements into the text file. But i have to pass the file name and also path as a user enterable parameter.
please suggest me to proceed further.
for ex: i am storing it as
output:=text_io.fopen(c:abc\def\out.txt','w');
right now i am giving like this and storing the data, but now i have to allow file name and path as user parameter.
please suggest me.
Thanks..

please suggest me.Well, how hard can it be?
You have to get those two parameters from your application into two variables, say "v_filename" and "v_pathname", and then create the file just the same way using the variables to construct the full path :
output:=text_io.fopen(v_pathname || '\' || v_filename,'w');

Pass parameter name as table name

I tried to append a parameter name (area) to the name of the table through a stored procedure. As we're using CIS, the @area reference doesn't work -- instead we use ?. The SP is simple:
declare @sql nvarchar(2000)
set @sql = 'select 1,2,3 from table_'+@area+'where <condition 1>'
execute sp_execute @sql
Executing this SP shows up a long list of errors.
Any help is deeply appreciated.

Post the actual and complete procedure and not just the part you think is relevant.
Post at least some of the complete and actual error messages you have received.
Lastly I will assume that your code has been edited for posting. Assuming you did not add any additional errors during this editing, then perhaps you simply need to add a space between the table name and your where clause. In other words, change
from table_'+@area+'where <condition 1>'
to
from table_'+@area+' where <condition 1>'
And as always, it would help you and your readers to post the actual string that you are attempting to execute. Simple logic errors in assembling your string are difficult to diagnose when you don't actually "see" the executed statement.

How do I Pass a parameter to a SQL Component Task where the source SQL statement is also a variable

Hi,
I have been tasked with making a complex package more generic.
To achieve this I need to pass a parameter to a SQL Component Task where the source SQL statement is also a variable.
So to help articulate my question further I have create a package and database as follows; -
USE [KWPlay]
GO
/****** Object: Table [dbo].[tblTest] Script Date: 05/14/2014 17:08:02 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[tblTest](
[ID] [bigint] IDENTITY(1,1) NOT NULL,
[Description] [nvarchar](50) NULL,
CONSTRAINT [PK_tblTest] PRIMARY KEY CLUSTERED
[ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
I populated this table with a single record.
I unit tested the SQL within SSMS as follows;
SELECT * FROM dbo.tblTest
Result; -
ID
Description
1
Happy
DECLARE @myParam NVARCHAR(100)
SET @myParam = 'Sad'
UPDATE dbo.tblTest SET [Description] = @myParam FROM dbo.tblTest WHERE ID = 1
SELECT * FROM dbo.tblTest
Result; -
ID
Description
1
Sad
Within the package I created two variables as follows; -
Name: strSQL
Scope: Package
Data Type: String
Value: UPDATE dbo.tblTest SET [Description] = @myParam FROM dbo.tblTest WHERE ID = 1
Name: strStatus
Scope: Package
Data Type: String
Value: Happy
I then created a single ‘Execute SQL Task’ component within the control flow as follows; -
However when I run the above package I get the following error; -
SSIS package "Package.dtsx" starting.
Error: 0xC002F210 at Execute SQL Task, Execute SQL Task: Executing the query "UPDATE dbo.tblTest SET [Description] = @myParam FR..." failed with the following error:

The Execution method succeeded, but the number of errors raised (1) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the
errors.
SSIS package "Package.dtsx" finished: Failure.
I also tried; -
Name: strSQL
Scope: Package
Data Type: String
Value: UPDATE dbo.tblTest SET [Description] = ? FROM dbo.tblTest WHERE ID = 1
However I received the error; -
SSIS package "Package.dtsx" starting.
Error: 0xC002F210 at Execute SQL Task, Execute SQL Task: Executing the query "UPDATE dbo.tblTest SET [Description] = ? FROM dbo...." failed with the following error: "Parameter name is unrecognized.". Possible failure reasons: Problems with

Therefore the answer was to put the parameter number rather than the parameter name under the parameter mapping tab-> parameter name column.

I need to use a reserved word as parameter name in proc called from URL

Let me preface this post by saying I already know this is terrible to attempt, but it's short term fix only.
Ok, so I have to create a procedure that will be called by a vendors application via a API that calls our URL to send data over. The terrible part is
that the API they have uses the parameter FROM=vendor_data A change is on the way so in the future the API won't use FROM as a paramter, so this isn't something I want to do, but it's a workaround.
So the nastiness is this..., I can create a procedure that'll compile when I enclose FROM in double quotes "FROM" as my input parameter
but if I try to call my procedure via URL (as their application will do) the procedure isn't working. I searched for someway to do an inline
replace of the FROM parameter to something else, but no luck. I'm open to all positive comments. I cannot go outside of Oracle
to do this, so I can't call a shell script and replace. Basically I need some way to use a reserved word as a parameter name, and then be able to call
that proc from a URL, or someway to change the FROM in the URL inline. Any help on this admittedly whacky situation would be appreciated much.
I tried ...\myproc?from=text
...\myproc?"from"=text
...\myproc?'from'=text
proc is simple test procedure
create or replace procedure myproc
("from" in varchar2 default 0)
is
v_from varchar2(30);
begin
v_from:="FROM";
insert into test(col1) values(v_from);
end;
**** Update
I didn't get any more replies but came to a solution that I thought I'd post. It's much better, more elegant and maybe can help others.
So instead of using FROM as the parameter name I did some research and decided I can use flexible parameters. Basically you end up having
2 input parameters for a procedure, one holds a parameter name the other holds the parameter value. They get loaded into arrays
and you access the values with regular name_array(1), value_array(1), etc. ?v=parameter&v2=value
Once I figued I could use flexible parameter it took me tons of research to find out the actual syntax. I'll post some examples for others
later, but was suprised with the lack of resources consideriing how "flexible" they are.
Thanks again for the replies. Cheers.

Scott,
Thanks for the reply. I'm not familiar with the wwv_flow_epg_include_mod_local, however I know that the
myproc is available via URL. I passed the my procedure name(myproc) on to the dba a while back to make it "accessible" so, I'm assuming that he
added it to this the www_flow_epg_mod_local (assuming this has something to do with access control).
If I modify myproc procedure and remove "FROM" as the input variable, and replace with say,
IN_FROM I can then call the procedure via the URL ./myproc?in_from=test without any problems.
I'm pretty confident that it's the "FROM" that is the hurdle and not a security or setup issue. The proc is fine to call from the URL until I got the curveball that the only available parameter was FROM. How the URL should be when inputing to that parameter?

Pass a parameter from webi to Xcelsius

Hi all,
Anybody knows how to pass a parameter from a webi report to Xcelsius via URL?
I need to refresh the Xcelsius data with a parameter coming from the webi report. With Live Office works but only the first time: the data is not being refreshed in Xcelsius everytime I change the parameter in the webi report.
I'm thinking in someting like openDocument.jsp but how do I read this parameter in Xcelsius? Which connection should I use?
Thank you very much,
jon

Hi Peter,
the link provided refers to Xcelsius V4.5.
In Xcelsius 2008 you have to control Flash Vars in the Data Manager.
Go to the Data Manager, Add the Flash-Var Connection Type, Select CSV-FlashVar and define a name and a range.
But i am not sure if Xcelsius Engage can handle FlashVars, because i am only working with Enterprise.
Please take a look at your manual.
For sure there are other ways to import data during runtime. Take a Look at the Connections provided by Data Manager. (e.g. QaaWS, SSRS, LiveOffice, Webservices, ...)
Also take a look at the link below. It might be another nice option for "pseudo" data connectivity

MDO select query: how to control sort order using parameter

Hi experts, is there a way of controling the sort order of an MDO select query using some parameter?
I was thinking about using some statement like CASE [Param.1] WHEN 'abc' THEN [ORDER_NO]...END in sort section of the query but it is not working.
Of course I colud go for various select queries...but I am wondering if it can be done using only one?
Any ideas?
Thanks for any help

Hi Marco,
Yes this can be achieved dynamically using SortExpr under dynamic link assignment in MDOAction block if you are using a transaction to call it.
Please check below thread:
Re: MDO Query Action Block In MII Transaction
Or else, this [Param.1] thing should work as well provided it doesn't get the logic part in it, just pass the columns names separated by comma. Haven't tried it though, will check it for you.
Best Regards,
Swaroop

Ref Cursor - how to access through parameter name

Hi,
I'm using the below table and sample data. The below script named 'Script1' works well, my concern is values for the first and second parameters need to be used for the thrid and fourth one as well.
When I try with 'Script2' it gives "ORA-01008: not all variables bound ORA-06512: at line 17" error. I know Paramterized cursor can handle this effecively, since it is a dynamic SQL, I need to use from a parameter table, I don't have any control over the number of parameteters, parameter name, type and other things. So, I cannot go for parameterized cursor.
As of now, for my requirement, Script1 works fine, is there any way to make Script2 to work as well, I need to pass paramters by name, not by position, please give your suggestions, thank you.

This link shall answer your Question. PL/SQL Dynamic SQL.
If it had been an Anonymous Block, your code would work through.
Please see demonstration below:
create or replace procedure emp_data (dep_id    number, sal   number, emp_id    number)
is
l_cnt   number;
begin
select count(*)
    into l_cnt
    from hr.employees
   where department_id = dep_id
     and salary >= sal
     and employee_id > emp_id;
dbms_output.put_line('Count :: ' || l_cnt);
end;
declare
l_cnt           number;
begin
execute immediate 'begin emp_data(:1, :2, :2); end;' using 20, 100;
end;
anonymous block completed
Count :: 2
--Trying the Similar example as in your OP.
--Execute the same Select statement as in emp_Data with Bind Variables;
declare
l_cnt           number;
begin
--execute immediate 'begin emp_data(:1, :2, :2); end;' using 20, 100;
execute immediate 'select count(*)
    from hr.employees
   where department_id = :1
     and salary >= :2
     and employee_id > :2' into l_cnt using 20, 100;
dbms_output.put_line('Count :: ' || l_cnt);
end;
Results in error :- ORA-01008: not all variables bound

Passing a parameter while calling a web dynpro application on portal

hi
I am having a web dynpro application which retrieves data from R/3 system via RFC using Jco destinations define in the Portal.
Now we have different kinds of portals running on the same WAS, now I want the application to run which access data from different R/3 systems thru different JCo destinations.
I need to create a logic such that mu application runs fine on any portal with any Jco destination.
Is there any provision to achieve this.
kindly let me know about this.
Thanks and regards
kris

Gopi,
there's an parameter called "sap-wd-arfc-useSys" you can pass to the application, to change the used JCo-Connection (read more at http://help.sap.com/saphelp_erp2005/helpdata/en/f4/651741f163f023e10000000a155106/frameset.htm)
so, if you're running the WD-aaplication on <b>one</b> WAS and call it from different portals, you have to create three (or six with the META-connections) JCo-Connection on your WD-WAS.
In a WD-application you can access URL-Parameters with:
WDWebContextAdapter.getWebContextAdapter().getRequestParameter("<your URL Parameter-Name>");
