HTTP Adaptor - Calling GET operations with parameters

Hi Guys,
I have to call a REST HTTP service on an external system. This is a GET operation (that the HTTP Adaptor has an option for so no initial prob there).
However, a REST GET seems to not accept an xml message as input and in fact needs to be called as a URL string. Further more, the parameter format has to be 'just right'....
The URL that needs calling is as follows, note the parameter format of <id type>.<value>
http://somewebsite/api/rest/acs/customer/uuid.1234
Now, what I don't know is how I can successfully ping this GET service using the HTTP adaptor -- I have been able to define the operation, mark it as a GET etc, but it seems to want a DTD for an input schema and this is not relevant here.... Also, if I didn't have a DTD for input schema, how could I set up the call in a Query transform in any case...?
I'm looking for advice on the HTTP adaptor generally for REST GET and POST calls, and also for the specific problem as above.
Any help would be fantastic!
Thanks,
Flip.

Hi,
Thanks for the response.
Can you elaborate a bit about the GET/SET and the non-support of REST? One of the settings when defining an HTTP Adapter operation is to specify if the operation is a GET or a POST -- doesn't this suggest that it does know how to call a REST GET in some way? Otherwise, what kind of things CAN be called via HTTP Adapter?
Thanks!
Flip.

  • FRM-92101 Error by calling the form with parameters

    Hi All!

    Hi Sergei,
    I've just finished a three day search for a FRM-92101problem, so I want to post my case, just in case it helps someone.
    My case is similar to yours, in that you have a Forms 6i form migrated to 10g and deployed on Linux, although my problem was "very" specific, and thus very hard to find, this might give you some light.
    I had a visual attribute that defined the property "Fill Pattern" as "none" applied to a canvas, and it deployed without any problem on 10gR2/Windows, but when deployed on Linux (10gR2/SUSE 9) it would abort the application getting a FRM-92101.
    The solution in this case was just changing "none" to "Transparent".
    Hope this helps.
    Regards,
    Miguel.

  • Calling stored procedures with parameters with the Database Connectivi​ty Toolkit

    Hi all,
    I am new to the forum and am having difficulty finding a solution to a particular problem I am having regarding using the LabVIEW Database Connectivity Toolkit on a project I am currently working on at my job.  I have a database in which I have tables and stored procedures with parameters.  Some of these stored procedures have input, output, and return parameters.
    I have been trying to follow this example but to no avail:  http://digital.ni.com/public.nsf/allkb/07FD1307460​83E0686257300006326C4?OpenDocument
    One such stored procedure I am working on implementing is named "dbo.getAllowablePNs", which executes "SELECT * from DeviceType" (DeviceType is the table).  In this case, it does not require an input parameter, it has an output parameter that generates the table [cluster], and has a return parameter which returns an integer value (execution status code) to show if an error occurred.  The DeviceType table has 3 columns; ID (PK, int, not null), PN (nvarchar(15), null), and NumMACAddresses (int, null).  I have gone over many examples and have talking to NI support to try to implement this and similar stored procedures in LabVIEW but have not been successful.  I am able to connect to the database with the Open Connection VI without error, but am running into some confusion following this step.  I am then trying to use the Create Parameterized Query VI to call the stored procedure and set the parameters.  I assume I would then use the Set Parameter Value VI for each parameter that is wired into the parameters input on the previous Parameterized Query VI?  I am also having some confusion during and following these steps as well.  I would greatly appreciate any advice or suggestions anyone might have in regards to this situation as I am not a SQL expert.  Also, I would be happy to provide any more information that would be helpful.
    Regards,
    Jon
    Solved!
    Go to Solution.

    Also, I don't know if this would be helpful but here is the actual stored procedure in SQL:
    CREATEPROCEDURE [dbo].[getLastSequenceNumber]
    @p1 nvarchar(10)='WO-00000'
    AS
    BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SETNOCOUNTON;
    -- Insert statements for procedure here
    selectmax(SequenceNumber)from Devices where WorkOrderNumber= @p1
    END

  • Calling Stored procedure with Parameters in PowerPivot DataModel

    Hi All,
    I wanted to call a SQL stored procedure from PowerPivot(Excel) on based on changing slicer's value. 
    Currently, we can call stored procedure wihtout any parameter from Data Model tab using 
    Exec stored_proc_name in Table Properties window.
    What if I want to call the same procedure with a parameter whouse value will come by changing slicer's value. I  meant, changing slicer value will act as a parameter to that stored procedure & it should return updated results. 
    Is this possible in PowerPivot?

    Hi Rameshwar,
    According to your description, you call a SQL Server stored procedure in PowerPivot data model, now the problem is that you need to pass a parameter to the stored procedure, right?
    Based on my research, it seems that we cannot achieve this requirement directly in current version of PowerPivot data model. Here is a similar thread for you reference.
    https://social.msdn.microsoft.com/Forums/sqlserver/en-US/5350228d-bc62-4a3b-a1a6-e847483e2858/powerpivot-for-excel-2013-call-execute-stored-procedure-with-parameters?forum=sqlkjpowerpivotforexcel
    If you have any concern about this behavior, you can submit a feedback at
    http://connect.microsoft.com/SQLServer/Feedback and hope it is resolved in the next release of service pack or product. Your feedback enables Microsoft to make software and services the best that they can be, Microsoft might consider to add this feature

  • In SQLScript, how to use EXEC to call another procedure with parameters in procedure?

    Hi experts,
    In SQLScript, How to use EXEC to call another procedure with input and output parameters in procedure？thanks very much

    Hi Sagar,
    thank you! I generate another procedure with an input parameter and an output parameter in a procedure. Then i need to call the generated procedure using EXEC. Here is my code:
    create procedure ftest1(out sum_num bigint)
    as
    begin
    declare fa_output bigint;
    declare v_sql_drop varchar(200);
    declare v_sql varchar(500);
    declare cursor c_cursor1 for select num from TABLE1;
    --v_sql_drop := 'drop procedure fe';
    --exec v_sql_drop;
    v_sql := 'create procedure fe(in i_num bigint,out o_num bigint) as begin';
    v_sql := :v_sql || ' o_num := :i_num * 2 + :i_num * :i_num;';
    v_sql := :v_sql || ' end';

    else
    sum_num := :sum_num + fa_output;
    end if;
    end for;
    close c_cursor1;
    end;
    The underline code is using exec to call the generated procedure. But this method cannot work. Any suggestion? thanks again!

  • How to call discoverer report with parameters over http link?

    Hi!
    I'm using oracle application server 9.0.4 (incl. discoverer).
    I have an oracle portal report where I want to call a discoverer report for each line over a http link. It is always the same discoverer report - with each line I want to pass parameters to my discoverer report.
    How can I pass parameters to the report? Is there another way rather than using GET parameters?
    Thanks
    Markus

    Hi Markus
    You need to determine whether you can in fact call a Discoverer report using a URL before linking it in Portal. You need to run the report in Viewer first and then see copy the URL from the address line of the browser. Then you open another browser and paste the URL. You may well be prompted for a username and password but hopefully the correct report with the right parameters will then execute.
    Assuming this works you then paste the same URL link into Portal and you should be able to get the report to run.
    Best wishes

  • Call stored procedure(with parameters) via odbc

    In my application I like to use the below statement to call a stored procedure with parameter and return a result set.

    If I change the statement to:
    {CALL PP.getPerson(?')}
    and bind a parameter and its value, it will work.
    My question is, is it possible to call a stored procedure via ODBC without binding parameters in application? I mean, what will be my SQL equivalent if I don't want to do parameter binding in my application?

    I have following problem: I wrote a plugin for Illustrator CS2 in C++ and now I would like to call a function of the plugin from outside of illustrator (from a JavaScript).
    This can be done with the Actionsuite. But how could I then give some parameters to my function?
    For example:
    In the plugin, I have a function "void myFun(char * test)" and I want to call this function in JavaScript with test="Hello World" for example.
    The only possible way right now seems to write parameters into a file and open that file in the plugin to "receive" them.

    Hi,
    Could you send your plugin coding.
    Regards,

  • How to call a function with parameters in ScriptStart function

    i am trying to call ScriptStart function from SUD dialog. This is how iam calling Call ScriptStart(path & "test.vbs","abc") abc is function which is written test.vbs. It is working. But when i want to pass some parameters to the abc function of test.vbs. It is not working why. can anybody suggest where i went wrong. I am calling the same function as Call ScriptStart(path & "test.vbs","abc(" & text1.Text & ")"). It is not working why ? Is the ScriptStart function only point to functions. it does not take any parameters or waht ?

    Hi abc421,
    Another option in addition to UserCommands would be to use ScriptInclude(path). If you execute a ScriptInclude(path) command at the beginning of your VBScript, then all the functions and Subs in the VBscript located at "path" are now available to you-- including passing parameters and receiving return values from functions. If you are calling a VBscript that uses only VBScript variables, then this is the preferred method.
    If instead you are calling a VBScript that uses global DIAdem variables declared in a VAS file (their variable names all end with the "_" character), then those parameters are already available at the subroutine called with ScriptStart(path, routine).
