Calling external C procedures from PL/SQL

Hello,
The first two development steps for external C procedures are:
1. Create and compile the external procedure in 3GL.
2. Link the external procedure with the standard shared library at the operating system level.
For others, for example for 3. Create an alias library schema object to map to the operating system's shared library, i can see details of how to do this, but for first two, i see "Varies for each operating system; consult documentation".
My question is, how can 1 and 2 be done, in case of Windows? So i have the .c file, where i've written a procedure. And next what should i do for the first two steps?
Thanks

The "standard shared library at the operating system level", is that .dll file, isn't it?Yep. On Linux/Unix these are actually called shared libraries.

  • How to call external Perl routines from Pl/SQL - Urgent

    Available software in the Test Environment:
    1. Sun Unix 2.8
    2. Oracle 8.1.7 ( 8i)
    3. Perl 5
    Iam trying to call/execute perl scripts from PL/SQL using the DEMO_RDBMS.mk. I am able to call C scripts from PL/SQL, but actually want to call Perl scripts.
    The steps followed for for C are -
    1. Create and compile a simple C program to execute a unix command (eg., touch a file).
    2. Make a shared library of the above compiled program (object), i.e., load the compiled object module into a dynamic load library.
    3. Declare the above library in Oracle using SQL*Plus.
    4. Define a PL/SQL function or procedure to call the external routine.
    5. Test the external routine.
    The above steps run good for a C program, but step 2 fails when run for a Perl script.
    When I tried to use the following command for step 2 -
    make -f $ORACLE_HOME/rdbms/demo/demo_rdbms.mk extproc_callback \
    SHARED_LIBNAME=cmd_lib.so \
    OBJS=tst_cmd.pl
    got the following error -
    ld: fatal: file tst_cmd.pl: unknown file type.
    ld: fatal: File processing errors. No output written t cmd_lib.so
    *** Error code 1
    This gives me an indication that demo_rdbms.mk does not understand/interpret Perl scripts. Going through the demo_rdbms.mk suggests the same.
    My questions is - How do we call external Perl scripts/routines from PL/SQL ??
    Do I have to get a different version of "demo_rdbms.mk" ?
    PS: The perl scripts used above (tst_cmd.pl) is error free and works as intended in the unix environment.

    Iam trying to call/execute perl scripts from PL/SQL using the DEMO_RDBMS.mk. I am able to call C scripts from PL/SQL, but actually want to call Perl scripts. Well, C is a "compiler" language and Perl is interpreted. In a sense, C is not "scripts".
    When I tried to use the following command for step 2 -
    make -f $ORACLE_HOME/rdbms/demo/demo_rdbms.mk extproc_callback \
    SHARED_LIBNAME=cmd_lib.so \
    OBJS=tst_cmd.pl
    got the following error -
    ld: fatal: file tst_cmd.pl: unknown file type.
    ld: fatal: File processing errors. No output written t cmd_lib.soI guess this compiles an extproc "stub" with your object file, generating an external procedure. So the object file really needs to be an object file :-)
    My questions is - How do we call external Perl scripts/routines from PL/SQL ??I'd guess you need an embedded Perl interpreter in the external procedure.
    Not much help though I'm afraid :-/

  • Error when calling a stored procedure from a SQL Script

    Apologies if this is a really dumb question but I can't seem to call a procedure in package from a SQL script. I have a simple package.procedure containing a loop to populate a table. I would like to include a call to this procedure from my database install script, that also includes my CREATE and INSERT statements. I run the script using "@install_databae" and the CREATE and INSERT statements run fine. The script gives an error when it reaches the line below:
    exec lazarus.PopulateGridPositions;
    and gives the error.....
    BEGIN lazarus.PopulateGridPositions; END;
    ERROR at line 1:
    ORA-04063: package body "LAZARUS.LAZARUS" has errors
    ORA-06508: PL/SQL: could not find program unit being called: "LAZARUS.LAZARUS"
    ORA-06512: at line 1
    The procedure and package have both compiled without errors and the statement on its own works fine in SQL*Plus.
    I've obviously missed some fundamental concept with scripts and SQL. Please can anybody help me?

    And just checking:
    You have schema called LAZARUS, which holds a package named LAZARUS, which holds a procedure called POPULATEGRIDPOSITIONS?

  • Problems calling external C routines from PL/SQL

    Hi everybody!
    I'm not familiar with C programming in Unix, but I'm trying to make work an example to execute external procedures (developed in C) from PL/SQL.
    The example includes .c and .pc source files, which I have compiled succesfully.
    After that, links the .o files into .so to declare later as libraries in the Oracle database.
    The problem appears when I try to execute this procedures (from PL), when a I get the error:

  • Calling Managed CLR Stored Procedure from C++ SQL Server 2008 fails with Msg 2809

    I am trying to call a stored procedure from C++ (VS 2010).
    Here is what the stored procedure looks like:
    public class Validate
    [Microsoft.SqlServer.Server.SqlProcedure(Name = "ClientTest")]
    public static void ClientTest(out String res )
    { res = "50";}
    To create a stored procedure I deploy at first the assembly

    GO
    CREATE ASSEMBLY ClientTestAssembly
    AUTHORIZATION testLogin
    FROM 'C:\Users\test\Documents\Visual Studio 2010\Projects\TestCreationAssemblyCSharp\TestCreationAssemblyCSharp\bin\x64\Debug\TestCreationAssemblyCSharp.dll'
    and call 
    USE test
    GO
    CREATE PROCEDURE ClientTest (@res NVARCHAR(40) OUTPUT)
    AS
    EXTERNAL NAME ClientTestAssembly.Validate.ClientTest
    I can call my procedure direct in SQL Server Management Studio without any errors
    declare @res nvarchar(10)
    execute ClientTest @res OUTPUT
    print @res
    But when I try to call this procedure from C++ using CALL syntax
    SQLBindParameter(sqlstatementhandle, 1, SQL_PARAM_OUTPUT, SQL_C_CHAR,

    &pcbValue);
    res = SQLExecDirect(sqlstatementhandle, (SQLCHAR*)("{CALL ClientTest(?) }"), SQL_NTS);
    I get the Error 2809 with SQLSTATE 42000 and with statement 
    The request for 'ClientTest'
    (procedure) failed because 'ClientTest' is a procedure object.
    However, if I wrap my CLR stored procedure into a T-SQL stored procedure, like
    CREATE PROCEDURE myProc (@res NVARCHAR(40) OUTPUT)
    AS
    EXEC ClientTest @res OUTPUT
    and call then myProc instead of ClientTest
    res = SQLExecDirect(sqlstatementhandle, (SQLCHAR*)("{CALL myProc(?) }"), SQL_NTS);
    everithing works fine and I get 50 as result.
    I have no ideas what is the reason for that behavior.
    Thanks very much for any suggestion.

    I'm not an ODBC expert, but you might try following the sample here:
    Process Return Codes and Output Parameters (ODBC)
    To see if it also behaves differently for your CLR proc.

  • I want to call External Java class from the PL/SQL

    Hi,
    I am using Oracle Apps R11i (11.5.7), I wanted to call external Java class from the PL/SQL. This external Java class is residing in another application server.
    How do I do this.
    I know one way. Develop C routine in Oracle Apps to call external java class and call this C routine from the PL/SQL.
    Is there any simple method available? or any other method?
    Thanks in advance.
    -Venkat

    First of all, this is a Java application you're talking about, right (i.e. it has a main() function)? It's not just a class that you're trying to instantiate is it? If it's an application, you obviously have to start a new virtual machine to run it (rather than using the virtual machine built into the database like stored java). I'm a little leary of your mention of an "application server" as this would more commonly mean that a virtual machine is already over there running with access to this class. In which case, you'd typically interface with SOAP or some other RPC API.
    All that aside, as long as you have physical disc access (through NFS or whatever) to the class file, you could use a java wrapper class with a system call to do this. In fact, there is a thread in just the last day or so on this very forum that has the code to do just that (see " Invoking OS Commands from PL/SQL"). However, it's worth noting that the virtual machine will be running on the database server in this case and not the application server.

  • Calling a Web Service from PL/SQL Procedure

    How can you call a web service from a pl/sql package , also is it valid to call a web service from pl/sql according to Fusion Standards..

    Hi,
    On way we can call a web service is to pass the Web Service URL to UTL_HTTP package:

  • Is it possible to call a activeX control from PL/SQL...?

    Hi all,
    Is it possible to call a activeX control from PL/SQL...? If yes, please give me sample code or any link.
    Thanks,
    Pal

    The LoadLibrary() Win32 call is used to find the physical DLL and load it into memory. This API call first look in the current directory for the file, and then uses the PATH environmental variable to try and find the file.
    Thus you need to make sure PATH is properly set. A Win32 process runs in a 32bit VM (Virtual Machine). Been a very long time since I did Windows server side development, but as I recall this VM inherits the default o/s environment (unlike Unix where the parent process environment is inherited).
    You can set the environment using the Properties menu of the System desktop icon (or via Control Panel).
    However.. Oracle does not run as your user. Typically it is installed as the o/s user Oracle and this user owns all the Oracle processes (listener, instance, etc).
    So you will need to make sure that this user's environment is correctly configured... Further more than this, I'm out of my depth. Did a lot of Windows stuff back in the 90's, but for many years now I'm only using Unix/Linux professionally - with Windows being my console platform for playing games at home. :-)
    On the Linux/Unix side, I configure the environment variable via the Listener. E.g. Under the entry SID_LIST_LISTENER, I configure the external procedure handler as follows:
    (SID_DESC =
    (SID_NAME = PLSExtProc)
    (ORACLE_HOME=/tjs-dev/app/oracle/product/10.2.0)
    (PROGRAM = extproc)
    (ENVS = "EXTPROC_DLLS=ANY")
    )No idea how this applies and works on the Windows side.

  • Calling a stored procedure from within a ViewObject

    Is it possible to make stored procedure call from within a BC4J ViewObject? Basically something like this:
    select * from table(f1(3)); where f1 is a table function. Using Oracle's pipelined table functions?
    If not, is it possible to call a stored procedure from Java and have the returned results be put back into a BC4J RowSet.
    In addition, is there a way to create a JDBC Resultset from a BC4J RowSet?
    We need to be able to dynamically create our SQL statements (the entire SQL, not just the where clause) but are required to have these sql statements generated/executed from within a pl/sql stored procedure in the database.

    Is it possible to make stored procedure call from within a BC4J ViewObject? Basically something like this:
    select * from table(f1(3)); where f1 is a table function. Using Oracle's pipelined table functions?
    Yes. Using our expert-mode query feature this is possible.
    is it possible to call a stored procedure from Java and have the returned results be put back into a BC4J RowSet.
    Yes. See this article about basing a view object on a REF CURSOR:
    http://radio.weblogs.com/0118231/2003/03/03.html
    In addition, is there a way to create a JDBC Resultset from a BC4J RowSet?
    No. Not directly. What's the business requirement here so I can understand better?
    We need to be able to dynamically create our SQL statements (the entire SQL, not just the where clause) but are required to have these sql statements generated/executed from within a pl/sql stored procedure in the database.
    REF CURSOR would work fine, or if it's just the statement that needs to be generated dynamically, you could fetch the text of the SQL statement from the stored procedure, then use createViewObjectFromQueryStmt(). Although this has runtime overhead involved with describing the query.
    The REF CURSOR based approach is probably best for this.

  • Calling Oracle Stored Procedure from BC4J JSP App

    I am on an extremely tight deadline and am trying to get my JSP application to use an Oracle Stored Procedure. I need to take some input from the user and send these values as parameters. Has anyone worked with Stored Procedures in JDev3.1? Please reply with some sample code if possible.
    Thanks.

    Hi,
    Someone posted a similar request the other day. Here is my response to them:
    Basically, you need to create a custom method from your JSP's ViewObject, which calls the stored procedure. You can then call the ViewObject's custom method from the JSP client.
    Here is how I have done it:
    1. Choose the ViewObject that your JSP is based on and choose 'Edit' from the context menu.
    2. On the Java tab of the ViewObject wizard, choose Generate Java File checkbox for the View Object Class and click the Finish button. A file is created under the ViewObject node in the Navigator named 'viewobjectImpl.java'.
    3. Open the viewobjectImpl.java file in the code editor and create a method to call your stored procedure (see sample code below).
    4. Compile the VOImpl.java file.
    5. Choose the view object again, and choose Edit again from the context menu.
    6. On the Client Methods tab, you should now see your method appear in the Available field. Select it and shuttle it to the Selected field.
    7. Click Finish to leave the VO wizard, and rebuild your Business Components project.
    8. In your JSP, call the custom method (see sample code below).
    sample code for custom method calling a stored procedure from VOImpl.java file:
    public int getTotalHits(String mon, String year) {
    CallableStatement stmt = null;
    int total;
    // the call to the PL/SQL stored proc
    String totalhits = "{? = call walkthru.total_hits(?,?)}";
    // use the AM conxn 2 call storedproc
    stmt = getDBTransaction().createCallableStatement(totalhits, 1);
    try
    // Bind the Statement Parameters and //Execute this Statement
    stmt.registerOutParameter(1,Types.INTEGER);
    stmt.setString(2,mon); stmt.setString(3,year);
    stmt.execute();
    total = stmt.getInt(1);
    catch (Exception ex)
    throw new oracle.jbo.JboException(ex);
    finally
    try
    stmt.close();
    catch (Exception nex)
    return total;
    sample render code for calling custom method from JSP custom bean:
    public void render() {
    int totalhits;
    try
    Row[] rows;
    // Retrieve all records by default, the qView variable is defined in the base class
    qView.setRangeSize(-1);
    qView.first();
    rows = qView.getAllRowsInRange();
    // instantiate a view object for our exported method
    // and call the stored procedure to get the total
    ViewObject vo = qView.getViewObject();

  • Calling packaged stored procedure from Java

    Hi All,
    I'm trying to call a stored procedure from Java but I'm having
    problems with registrating the output parameter. I'm getting
    the error: Conflicting parameters.: sqltype=2003
    This is the stored procedure which is located in a package in
    the Oracle database:
    package Pack_GetAgencyInformation as
    Type InfoType is record ( agen_code varchar(3), agen_designation
    varchar(30), agen_adresse varchar(60), agen_tel varchar(12) );
    function GetAgencyInformation( P_AGENCE VARCHAR )
    return Pack_GetAgencyInformation.InfoType
    end Pack_GetAgencyInformation;
    This is the Java source from where I'm calling the procedure:
    //DriverManager.registerDriver (new
    oracle.jdbc.driver.OracleDriver());
         Class.forName("oracle.jdbc.driver.OracleDriver");
    Connection conn = DriverManager.getConnection
    ("jdbc:oracle:thin:@164.48.69.125:1521:ventes", "system", "*****
    // @machineName:port:SID,
    userid, password
    CallableStatement cs = conn.prepareCall("{ ? = call
    Pack_GetAgencyInformation.GetAgencyInformation( ? )}");
         try {
              cs.registerOutParameter( 1,
    oracle.jdbc.driver.OracleTypes.ARRAY);
         } catch (SQLException e) {
              e.printStackTrace();
         cs.setString(2, "001" );
         //ResultSet rset = cs.executeQuery();
    The stacktrace:
    java.sql.SQLException: Parametertypen conflicteren.:
    sqlType=2003
    at oracle.jdbc.dbaccess.DBError.throwSqlException
    (DBError.java:168)

    oracle.jdbc.driver.OracleCallableStatement.registerOutParameter
    (OracleCallableStatement.java:350)
    at dbAccess.main(dbAccess.java:25)
    I think it has to do with the type InfoType which is created in
    the Stored Procedure. I'm absolute no Oracle expert and I
    prefer not to make changes to the Oracle database. So any
    solution in Java is welcome!
    BR, H.Rietman

    I managed to get it to work only by changing the stored
    procedure. I have changed the return type record to a Ref
    Cursor type (had to change alot of code for this). It seams
    that Oracle JDBC drivers DON'T support the Record type as a
    return type.
    So the next question is: is it possible to typecast a record
    type to a ref cursor type in Oracle. In this way I can easily
    change the return type for the stored procedures.

  • Calling Oracle store procedure from Crystal 11 command

    I need to call Oracle store procedure from Crystal Command. The Store proc has ref cursor. Is it possible. Can you post few examples?
    Also, is it possible to have multiple sql statements in a Crystal Command, when working with Oracle 10g?
    It is working for SQL server.

    Please re-post if this is still an issue to the Data Connectivity - Crystal Reports Forum or purchase a case and have a dedicated support engineer work with you directly.
