User-Defined Function and Context Manipulation

Hi Mapping Gurus, I need your help.
I have a user-defined function and one of my input parameter (c) is in a loop (EDI segment).  So one, if I execute my function I get:
Exception:[java.lang.ArrayIndexOutOfBoundsException: 0]
If I change the context or use the remove context node function it’s working but it’s always taking the first row in consideration since I'm using c[0] .  Here is the logic:
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[0]"'";
So since c is an array [], I have tried different logic to get to the right row.
1- I tried using another parameter (e) to pass a counter or an index to my function.  So each time it's looping, it's passing a new value to the function but I’m still getting the first row and I’m not to sure why?
int G = Integer.parseInt(e[0]);  // e[] = My counter field
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[G]"'";
2- I tried using a parameter stored in the container:
String Num;
Num = (String)getParameter(“counter”);
if (Num == null)  G = 0;
else
G = Integer.parseInt(Num);
G = G + 1;
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[G]"'";
Num = "" + G;
setParameter(e[0], Num);
and I’m still getting the first one, look like it’s using a different container each time it’s looping so the Value is always the same?
4- I created a new user-defined function with the container logic, then it’s working but I’m back to the same problem in my main function, it’s only looking at e[0] for my counter all the time.
5- I tried using the Seeburger Java Variables and guess what in the main fonction, as new UDF,... and guess what, same result!
So anybody out there that was able to get UDF's working into a multiple context scenario?
Am I missing something?
I will reward points and beer for any help!

This is one of the text with passing a counter to the function to try to go to the right row in the array since I'm doing a remove context and I'm getting all the d_234's:
public void ReadTable(String[] a,String[] b,String[] c,String[] d,String[] e,ResultList result,Container container){
int G = Integer.parseInt(e[0]); // My counter
String var;
String DBTABLE = a[0];
String lookUpField = d[0];
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[G]"'";
Now this one was with the internal container logic:
int G;
String DBTABLE = a[0];
String lookUpField = d[0];
String Num;
Num = (String)getParameter(e[0]);
if (Num == null)  G = 0;
else
G = Integer.parseInt(Num);
G = G + 1;
Num = "" + G;
setParameter(e[0], Num);
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[G]"'";
And now with the Seeburger Variables:
int G;
try {
VariableBean be=VariableFactory.getVariableInstance("");
G = Integer.parseInt(String.valueOf(be.getStringVariable("yves")));
} catch (Exception f) {
throw new RuntimeException(f);
String DBTABLE = a[0];
String lookUpField = d[0];
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[G]"'";
try {
G = G + 1;
Num = "" + G;
VariableBean be=VariableFactory.getVariableInstance("");
be.setStringVariable("yves",Num);
catch (Exception f) {
throw new RuntimeException(f);
All 3 logics were returning always the first row or a counter of 1 if the logic is in the main ReadTable function.

  • Where are User Defined Functions and Stored Procedures kept in SQL Server?

    Hi,
    I have a growing list of Stored Procedures and User-Defined Functions in SQL Server, and would like to be able to list all my user SP and UDF easily.
    Is it possible to write a query to list all SP and UDF?
    I saw the following specimen code in an SQL book, but am not sure this is what I need because I could not make it work.
    SELECT *
        FROM INFORMATION_SCHEMA.ROUTINES
    WHERE SPECIFIC_SCHEMA = N'CustomerDetails'
        AND SPECIFIC_NAME = N'apf_CusBalances'
    I tried:
    SELECT *
        FROM INFORMATION_SCHEMA.ROUTINES
    but it does not work.
    Suppose all my SP are named following this pattern:
        dbo.usp_Storeproc1
    How would I modify the above code? or is there a better code?
    Thanks
    Leon Lai

    Hi ,
    try this to get list of all stored procedures:
    SELECT *
    FROM sys.procedures where name like 'dbo.usp%'

  • User-defined function in FILTER clause

    hi,
    can i create the user-defined functions and use them in the FILTER clause in the sem_match function? there are some built-in functions for the FILTER clasue. however, only one function (DATATYPE(literal)) support for date/time in the built-in functions. i want to implement some user-defined funcitons in the FILTER clause which can check time intervals in ontology. there are some functions about valid time in the WorkSpace Manager such as WM_OVERLAPS, WM_CONTAINS,WM_MEETS, etc. so, can i write some functions using the these valid time functions in WM and use them in the FILTER clause? thanks a lot in advance.

    Hi Hong,
    You don't need user-defined functions to do time interval comparisons. You can directly compare xsd:dateTime values with the built-in comparison operators: <, >, =, !=, <=, >=
    For example, the query pattern below could find events that happened during event1 if we have data such as:
    :event1 :startTime "2013-01-01T03:15:00Z"^^xsd:dateTime .
    :event1 :endTime "2013-02-01T02:15:00Z"^^xsd:dateTime .
    :event2 :startTime "2013-01-11T14:15:00Z"^^xsd:dateTime .
    :event2 :startTime "2013-01-14T12:15:00Z"^^xsd:dateTime .
    SELECT ?e2
    WHERE
    { :event1 :startTime ?e1_st; :endTime ?e1_et .
    ?e2 :startTime ?e2_st; endTime ?e2_et .
    FILTER (?e1_st < ?e2_st && ?e2_et < ?e1_et) }
    In general, it is trivial to convert interval relations such as meets and overlaps to conditions on start and end times.
    Hope this helps.

  • User Defined Function Error - Can't find function

    Hi All,
    Version: 11.1.1.4
    I created a user defined function and added it to one of my BPEL Processes. I can see the function in JDeveloper and can compile the project without issue. We placed the jar file out on the SOA Server following the oracle user defined function examples. After placing the file out on weblogic I was able to successfully deploy the project.
    Oracle Deployment Steps:
    To deploy user-defined functions to runtime:
    1. Copy the user-defined function JAR files to BEA_Home/user_projects/domains/domain_name/lib or a subdirectory of lib.  Where domain_name is the name of the Oracle WebLogic Server domain (for example, soainfra).
    2. Restart the Oracle WebLogic Server.However, when I try to run the composite application I get the below error. I am not really sure why it can't find the Function? The jar is out on the server and the jar was added to the project?
    Error:

    try putting the jar location explicitly in weblogic server's classpath i.e. add BEA_Home/user_projects/domains/domain_name/lib to wls classpath and restart server.

  • Java user-defined function for mapping a complex structure

    All,
    Hope one of you can help me with this. I have a structure with over 15 fields and would like to concatenate all the fields into one target field and while I do this, I need to ensure that each field is padded with blanks as defined the data type. Can one of tell me if this is possible with a java user-defined function and if so, what type of logic is needed.
    Input_MT
    Field_1  string len=10 "need"
    Field_2  string len=6 "java"
    Field_3  string len=7 "help"
    Field_4  string len=8  "asap"
    etc,
    Output_MT 
    DataOut string  "need      java  help   asap    "
    (for some reason the exact spaces in between the words disappear in my Preview message)
    I have several fields in the input mt and therefore I find graphical mapping using concatenate and my own user defined function padWithSpace too messy.
    Thank you for you help.

    Hi,
    If your final req is to write all these fields next each other in a file, you can configure this in receiver file adapter by specifying the fixed length for each field.
    If you want the padded string as your MM o/p, you can create a simple user defined funtion with 15 fields as input and 15 constants for their lengths, and find out the length of the each string and pad it with required no of spaces.
    int max_len = 10;
    int actual_len;
    actual_len = a.lengh();
    for(int i=0; i < (max_len-actual_len; i++)
    a = a.append(" ");
    return a;

  • Getting "Unexpected end of formula" error in user-defined function

    I created a user-defined function and registered it successfully in Discoverer Admin (10g), and it shows up in Discoverer Plus. However, when I call the function, I get this error:
    "Error in formula -- unexpected end of formula"
    If I hard-code in parameters, I can successfully run the function as such from Oracle SQL Developer:
    SELECT PAYLINETOT('2324', '111', to_date('01-Sep-2010'), to_date('31-Oct-2010'))
    FROM DUAL;
    But I still get the same error if I enter this in the calculation dialog in Discoverer:
    PAYLINETOT('2324', '111', to_date('01-Sep-2010'), to_date('31-Oct-2010'))
    Any idea what's going on and how to get this to work?

    Michael,
    I tried your suggestion, and this time I got a different error message that said that the function had not been registered with the EUL. I thought I had registered it, but when I checked, the return data type was wrong. I corrected it, and the function is "valid" in Discoverer Admin. Yet, when I go back to Discoverer Plus and attempt to use the function (and yes, I logged out and logged back in), I get the same error message:
    "Error in formula - unexpected end of formula - Error: Function PAYLINETOT has not been registered with the EUL."
    Any idea where the disconnect is? Are these two separate errors? How could Discoverer Admin tell me that the function is registered and Discoverer Plus tell me otherwise? And yes, I've made sure that the "Available in Desktop/Plus" checkbox is checked.

  • User - defined functions for calculating the taxes of state and country

    hi expects,
        how can write user-defined function in message mapping in which i want to calculate the states taxes (2500) and country taxes (5000) and give the result as grand total in output.please help me?

    Hi,
    Activities
    1. To create a new user-defined function, in the data-flow editor, choose Create New Function (This
    graphic is explained in the accompanying text), which is located on the lower left-hand side of the
    screen. In the menu, choose Simple Function or Advanced Function.
    2. In the window that appears, specify the attributes of the new function:
    Name
    Technical name of the function. The name is displayed in the function chooser and on the data-flow
    object.
    Description
    Description of how the function is used.
    Cache
    Function type (see above)
    Argument Count
    In this table, you specify the number of input values the function can process, and name them. All
    functions are of type String.
    3. In the window that appears, you can create Java source code:
    a. You can import Java packages to your methods from the Imports input field, by specifying them
    separated by a comma or semi-colon:
    You do not need to import the packages java.lang., java.util., java.io., and java.lang.reflect. since
    all message mappings require these packages and therefore import them. You should be able to
    access standard JDK and J2EE packages of the SAP Web Application Server by simply specifying the
    package under Import. In other words, you do not have to import it as an archive into the Integration
    Repository. You can also access classes of the SAP XML Toolkit, the SAP Java Connector, and the
    SAP Logging Service (see also: Runtime Environment (Java-Mappings)).
    In addition to the standard packages, you can also specify Java packages that you have imported as
    archives and that are located in the same, or in an underlying software component version as the
    message mapping.
    b. Create your Java source text in the editor window or copy source text from another editor.
    4. Confirm with Save and Close.
    5. User-defined functions are limited to the message mapping in which you created the function. To
    save the new function, save the message mapping.
    6. To test the function, use the test environment.
    The new function is now visible in the User-Defined function category. When you select this category,
    a corresponding button is displayed in the function chooser pushbutton bar. To edit, delete, or add the
    function to the data-flow editor, choose the arrow next to the button and select from the list box
    displayed.

  • Using a User Defined Function as a constraint within a temporary table.

    Hello, 
    I am trying to create a temp table that uses a UDF in a constraint. I'm getting the following error message 
    Msg 4121, Level 16, State 1, Line 1
    Cannot find either column "dbo" or the user-defined function or aggregate "dbo.CK_LoseTeamSportExists", or the name is ambiguous.
    I've tested the function and it works in other contexts. Any idea? All code below:  
    Thanks, 
    - Bryon
    create function dbo.CK_LoseTeamSportExists (@loseteam int, @sportid int)
    returns bit
    as
    begin
    declare @return bit
    if exists 
    select TeamID, sportid from Link_TeamSport
    where 
    TeamID = @loseteam 
    and
    SportID = @sportid
    set @return = 1
    else set @return = 0
    return @return
    end
    go
    create table #check
    SportID int
    ,WinTeamID int
    ,LoseTeamID int
    ,check 
    (dbo.CK_LoseTeamSportExists(LoseTeamID,SportID) = 1)

    Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules. Temporal data should
    use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect. 
    This is minimal polite behavior on SQL forums. 
    >> I am trying to create a temp table that uses a UDF in a constraint. <<
    You do not understand how SQL or any declarative language works! 
    We do not use UDFs (procedural programming)
    We do not use bit flags (assembly language).
    We do not use temp tables (mag tape files).
    We do not use integer as identifiers (what math do you do on them?)
    Your silly “Link_TeamSport” implies a pointer chain; we have no links in SQL. Where is the DDL? 
    Constraints are always predicates in any declarative language. 
    Do you know why you have to create a local variable to pass the non-relational flag back to the calling environment? FORTRAN I and II! These early languages has to use hardware registers in the first IBM computers to return results. In your ignorance, you mimic
    them! 
    We do not use if-then-else control flow in any declarative language. We have CASE expressions that we put where you have a local variable getting an assignment. 
    I see you also put the comma at the start of the line. We did that with punch cards, so we could re-use them 50 years ago. 
    In SQL, we would use REFERENCES to assure a team reference exists. We use names for teams because they are entities, not quantities: 
    CREATE TABLE Game_Results
    (sport_name CHAR(10) NOT NULL PRIMARY KEY,
     win_team_name CHAR(12) NOT NULL
      REFERENCES Teams(team_name)
       ON DELETE CASCADE,
     lose_team_name CHAR(12) NOT NULL
      REFERENCES Teams(team_name)
       ON DELETE CASCADE,
     CHECK (win_team_name <> lose_team_name));

  • User Defined Function Missing In EF 6?

    I'm using Entity Framework 6 and I have imported several user-defined functions like the one shown below, but it doesn't
    appear when I try to select the function in intellisense and the model doesn't recognize this function as a method on the EF context.  How do I call this function in EF 6?
    <Function Name="getCycleDate" Aggregate="false" BuiltIn="false" NiladicFunction="false" IsComposable="true" ParameterTypeSemantics="AllowImplicitConversion" Schema="dbo" ReturnType="date" />
    MCSD .NET developer in Dallas, Texas

    Hello DallasSteve,
    >> I have imported several user-defined functions like the one shown below,
    What is your UDF? If it is a TVF, starting from EF5, it is supported already:
    https://msdn.microsoft.com/en-us/data/hh859577.aspx
    However, it is a scalar function, unfortunately, as far as I know, even entity framework 6 doesn't suport generating calls for scalar functions by default. The workaround is to write a custom method like this inside your DbContext class, for example, there
    is scalar function as:
    CREATE FUNCTION [dbo].[Function20150410]
    @param1 int,
    @param2 int
    RETURNS INT
    AS
    BEGIN
    RETURN @param1 + @param2
    END
    When we imported it to the model, it would generate code in SSDL as:
    <Function Name="Function20150410" Aggregate="false" BuiltIn="false" NiladicFunction="false" IsComposable="true" ParameterTypeSemantics="AllowImplicitConversion" Schema="dbo" ReturnType="int">
    <Parameter Name="param1" Type="int" Mode="In" />
    <Parameter Name="param2" Type="int" Mode="In" />
    </Function>
    While, it will not generate a call method as a store produce, for a workaround, we could write a custom function as:
    [DbFunction("DFDBModel.Store", "Function20150410")]
    public ObjectResult<int> GetContentByIdAndCul(int id, int culture)
    var objectContext = ((IObjectContextAdapter)this).ObjectContext;
    var parameters = new List<ObjectParameter>();
    parameters.Add(new ObjectParameter("Id", id));
    parameters.Add(new ObjectParameter("Culture", culture));
    return objectContext.CreateQuery<int>("DFDBModel.Store.Function20150410(@Id, @Culture)", parameters.ToArray()).Execute(MergeOption.NoTracking);
    I suggest that you write this custom method a separate cs file since if we update the model, the original context call would be reset.
    Calling it as:
    using (DFDBEntities db=new DFDBEntities())
    var result = db.GetContentByIdAndCul(1, 1).FirstOrDefault();
    }s

    Regards,
    Varun

    Hi Varun,
    I guess I have answered a similar question just a few minutes before on very similar post from you. Just pasting the same here .................
    Are you trying to access the ASMA values from the SOAP header of the XI message for the source file name?
    First of all you need to Set the Sender File Adapter for Set ASMA and then file name. So it will work fine when you actually run the scenario end to end.
    But in the mapping tool when you test the mapping - there is not message header updated with the actual source filename - and whenever you try to read the FileName attribute in the message header from the UDF - it cannot find the object and returns a NullPointerException.
    I would suuggest for your mapping tool testing to be successful, have a check in the java code for null values,
    DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
    DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
    String ourSourceFileName = conf.get(key);
    If (ourSourceFileName != null)
       Return ourSourceFileName;
    Return "NoFileName.txt";
    Let us know if this works.
