Execution of a stored procedure in a Package in an Oracle schema?

I found solutions to guidance how to run stored procedures to an Oracle DB, for example http://blogs.oracle.com/adf/entry/call_db_stored_procedure_using.

However, I have a database where procedures are in the packages and I want to know if there a way, that they can be run using enterprise Java Bean.


See you soon.

Calling stored procedures has nothing to do with the Enterprise Javabeans directly. What you want to do, is to use JDBC to create a callable statement and follow these steps:

     Connection conn = ...; // fetch from a datasource for example
     CallableStatement ps = conn.prepareCall("call PACKAGENAME.PROCEDURENAME(?,?,?)");

      ps.setString(1, "InputParam1");
      ps.setString(2, "InputParam2");
      ps.registerOutParameter(3, java.sql.Types.VARCHAR);

      ps.execute();
      String res = ps.getString(3);

This example accepts two input parameters and an output parameter. Adapt to your own needs. And don't forget to add exceptions and a finally clause in which you close the statement and connection.

  • ODP 12 c version 3 with EF 6.1.1 I can't add Stored Procedure of a package to my model

    I use the ODP 12 c Release 3 (12.1.0.2.1), with Entity Framework 6.1.1 with the first database in MS Visual Studio 2013 update 4

    I have a MVC 5 (.Net Framework 4.5.2) project that connects to Oracle 11 G R2 Database server, an existing database (Tables, views and a pack of Stored procedures)

    I can add tables and use them successfully in my model
    I can add a simple stored procedure

    Here's the problem:
    I have my .edmx file right click and click on "update model from database...". «, on the 'Add' tab, I chose «Stored procedures and functions»
    I can see the list of procedures stored in the package (format packageName.usp) and check the box for the stored procedure of my package, then click 'Finish' to start the update process.

    No stored procedures have been added to my Model.Store


    The only possible exit I get the 'entity data model' is:
    Generated template file: Model1.edmx.
    Loading metadata from the database took 00:00:00.5803351.
    The model generation took 00:00:00.3761861.

    How to add a stored procedure from a package with the Entity Framework 6.1.1?

    I found the answer.

    When in the edmx model and you right click "Update Model database.

    Uncheck "Import selected stored procedures and functions in the entity model", select the package and update procedures. (It works)

    Then in "Model Explorer" under "Model. Store\ stored procedures/functions" you will see your procedures in the package (finally). Then their card in "Function Imports".

    I don't understand why unchecking import stored procedures works, but it does.

    I also found easier to simply call the procedure directly and not using Entity Framework, as all my procedures are: insertion, update and deletions and not all parameters mapped on the model for the view.

    This behavior is probably not related to the ODP and will happen when you run the same procedure as the same user of SQLPlus directly for example, so the PLSQL forum is probably a more appropriate place for assistance.

    What is 'KIKO. PACK_SP', line 205? Roles are disabled inside stored procedures, so you must have the permissions that are granted directly.

    It will be useful,

    Bind variables cannot be used for the dynamic execution of stored programs. Dynamic SQL using lexical rather than bind substitution must be used to run when the program name is not known until execution of the programs.

    declare
      sproc varchar2(25);

      sproc := :procname;
      dbms_output.put_line('procedure:'||sproc);

    end;
    

    It is a fundamental design flaw and a security disaster. It's stops essential compilation controls is performed and is open to attack by SQL injection and other security vulnerabilities. There is no good reason to do this.

    Hello

    Sorry for the inconvenience. After I posted this question I took a break and saw that the error was nothing, but I had given FNAME as parameter name in MS SQL. In oracle when I created the sp I created the parameter with p_FNAME. Where the schema defined in the language SSDL and CSDL, MSL had to be changed to MS, but since I want to that it would be same in different databases, I choose to have changed it in oracle stored procedure. The error msg is confusing, it should be something not found parameter or incompatibility etc.

    Thank you

  • The execution of a stored procedure from inside the cursor for loop?

    I posted this in the SQL Developer forum, but I tried in SQLPlus and get the same error, so I think it's an encoding issue.
    I have a piece of code that I'm trying to write that will only be executed once. The goal: we have three tables relating to the pieces of information. Each table has a column that stores the number of site that belongs to the part. We want to copy the parts of a site to about 130 sites which don't have any info on parts. The number of site is stored in another table. So I created three stored procedures, one for each of the three tables that we, who take 2 inputs: a source and destination site. Procedure names are: ptfile_copy_fac, ptxref_copy_fac and ptvndrs_copy_fac.

    The problem I have is that I can run the procedures in a separate worksheet in SQL Developer, but when they are integrated in this cursor for loop, I get the following message from SQL Developer:

    ORA-06550: line 23, column 11:
    PLS-00103: encountered the symbol "PTFILE_COPY_FAC" during the expected in the following way:
    := . (@ %; immediate)
    The symbol ': = ' was replaced by 'PTFILE_COPY_FAC' continue.

    He repeated this for each of the three methods. I have attached the code I am trying to run below. He expects an assignment operator, but I have no idea why.

    If there is a better way to do this, by all means let me know. I'm a SQL Server guy, I'm not sure how to do what I do using PL\SQL.

    Update the comments you make more sense of the code.

    EXECUTE is a SQLPlus command, change your code to

    dest_fac := fac_row.facility_num;
    ptfile_copy_fac(source_fac, dest_fac);
    ptxref_copy_fac(source_fac, dest_fac);
    ptvndrs_copy_fac(source_fac, dest_fac);

  • Compilation of a stored procedure that is frequently consulted

    RDBMS version: 10.2.0.4.0 in a 2 RAC node

    Our Production database is 24 x 7. Our development team has made a change in the code of the procedure frequently consulted.
    At some point this stored proc is accessible by at least 5 sessions.
    I was asked to compile this procedure with the new changes.
    Since this is a frequently viewed, I think that the only option I have left to compile this proc is stopped by the DB and launch it using
    STARTUP RESTRICT
    and then compile it. But, this procedure is actually headed by a DBMS_JOB, so even if I stop, when I restart, the work will resume i.e. that execution of the stored procedure. Right?

    I can't knock local listeners because they are listening to an another DB in the cluster.

    Is there another better way?

    ALTER system set job_queue_processes = 0 will stop the ease of use.

    You might also consider to define windows service and stop the practical execution of cowboy.

  • Forms - calls to rather than shares of standard database stored procedures

    After seeing the reports, I now start with shapes in the APEX. :)

    While I like the basic features offered by different Assistants, there is one thing that bothers me. After you create your form, you get basically 3 buttons (not counting cancel them) for different actions, each corresponding to an Action of database (SQL INSERT/UPDATE/DELETE). That's nice, but is not exactly what I want. I would replace the actions of database directly by the calls of stored procedures (in a package), one for each action. Would be nice, of course, to keep the benefits of the wizard, in particular in view of the fact that I would like to find a simple way to create standard forms. So, basically, I would create my forms in this way, but instead of linking the button action predefined database, do call a stored procedure. It's somehow possible and what would be the best way to achieve this?

    I am running 4.0.1.00.03 on an Oracle XE database APEX.

    Erwin

    Unfortunately it is only three as a limit.

    Instead (to link a page), you can change your link (s) to the form via a URL using the following syntax:

    f?p=App:Page:Session:Request:Debug:ClearCache:itemNames:itemValues:PrinterFriendly
    

    Use substitution variables, as in that above syntax and ItemNames and ItemValues through comma lists of names and values in the respective order and in this way you can send more than three on the next page.

    Hello

    What statemet is UserBean.java:35)?

    Second, create a new SysUserEOImpl()!

    If you want to call stored proc, put the java code calling stored proc in ViewRowImpl/ViewObjectImpl/ApplicationModuleImpl and export this code in the customer interface. Then put this method in the pageDef as a call him as an OperationBinding

  • How can I force DAC to run always full load for one of the task that executes the stored procedure? And remaining tasks load incremental in the second and sub sequent executions.

    Hello

    How can I force DAC to run always full load for one of the task that executes the stored procedure? And remaining tasks load incremental in the second and sub sequent executions.

    Thank you

    Jay.

    Hi if your task is running an informatica mapping you can set your DAC task to run the full mapping for incremental and full loads, so tab task just point to the mapping.

    Hope that helps.

    Thank you

  • Need to query to find stored procedures that takes great execution time

    Hi all

    I use the oracle version below:

    Oracle Database 11 g Release 11.2.0.3.0 - 64 bit Production

    PL/SQL Release 11.2.0.3.0 - Production

    CORE Production 11.2.0.3.0

    AMT for Linux: Version 11.2.0.3.0 - Production

    NLSRTL Version 11.2.0.3.0 - Production

    is it possible to find the name of stored procedure that take too long to run, I need those optimized all SPs.

    Is there a query as top queries that are used to find queries albums that have great time for execution...

    or y at - it another way to find the names of MS. I try with AWR report but showing only used the names of MS.

    Thank you

    No, it not there no such request as far as I know.

    or y at - it another way to find the names of MS.

  • execution of stored procedure in sql developer/sql more with a table setting?

    Hello

    I create a package with a procedure which has a cursor ref as output and a type as an input parameter.  Here is my definition of the package

    PACKAGE 
    -------
    CREATE OR REPLACE PACKAGE TEST
    As
      TYPE RefCursorType IS REF CURSOR;
      type intTableType is table of varchar2(50) index by binary_integer;
      
      PROCEDURE GETDATA (
              P_RECORDS OUT RefCursorType,           
               YEAR_LIST IN intTableType
      );  
    END;
    
    
    PACKAGE BODY
    -----------------------
    
    SET DEFINE OFF
    CREATE OR REPLACE PACKAGE BODY TEST
    AS 
    PROCEDURE GETDATA
    (
      P_RECORDS OUT RefCursorType,  
      YEAR_LIST IN intTableType  
    )
    AS 
    iYearList  IDTableType;
    BEGIN 
      --GET ARRAY COUNT
      IYEARLIST := IDTABLETYPE();
      IYEARLIST.EXTEND(YEAR_LIST.COUNT);
      
      --LOOP THROUGH LISTS AND POPULATE ARRAY
      FOR I IN YEAR_LIST.FIRST .. YEAR_LIST.LAST
      LOOP
      IYEARLIST(I) := IDTYPE(TO_CHAR(YEAR_LIST(I)));
      END LOOP;
      
       OPEN P_RECORDS FOR 
       SELECT CITHTML AS FORMATTED
        FROM dbTest.FORMATTED_HTML
      WHERE YEAR IN (SELECT * FROM TABLE(IYEARLIST))
      ;
      END GETDATA ;
    END TEST ;
    /
    
    

    I want to perform this procedure from the sql or sql developer more to see if it works properly.   The year field dbTest.FORMATTED_HTML is defined as varchar2 (20 bytes).  He has many years as well as text.

    I've used this in the past with simple stored procedures, but not those with a table setting

    var r refcursor;

    exec GETOLDDATA(:r,40);

    print r;

    How can I modify this to allow him to run my stored procedure?

    Thank you

    Just declare SQL, not type of PL/SQL:

    CREATE OR REPLACE

    TYPE Str50TblType

    AS THE TABLE OF THE VARCHAR2 (50)

    /

    CREATE OR REPLACE

    THE TEST PACKAGE

    IS

    GETDATA PROCEDURE)

    P_RECORDS ON SYS_REFCURSOR,

    YEAR_LIST IN Str50TblType

    );

    END;

    /

    CREATE OR REPLACE

    TEST OF PACKAGE BODY

    IS

    GETDATA PROCEDURE)

    P_RECORDS ON SYS_REFCURSOR,

    YEAR_LIST IN Str50TblType

    )

    IS

    BEGIN

    OPEN P_RECORDS

    FOR

    SELECT CITHTML AS FORMATTED

    OF dbTest.FORMATTED_HTML

    WHERE YEAR IN)

    SELECT *.

    TABLE (YEAR_LIST)

    );

    GETDATA END;

    END TEST;

    /

  • Cursor to another stored procedure return package

    Hello
    I am new to Oracle, and I have the following problem:

    I have a slider in a package that is defined like this:
    create or replace
    PACKAGE 'TestPACKAGE' AS
    DOWNLOAD_CURSOR cursor's select A.* from A Table1, Table2 B
    END TestPACKAGE;
    In reality, there is more than one package with different cursors. I want to use this DOWNLOAD_CURSOR in a stored procedure, function, or another package, to return to the client in a ref cursor
    Something like this:
    create or replace
    procedure aa_test (retCURSOR to sys_refcursor) is
    Start
    retCURSOR: = TestPACKAGE.DOWNLOAD_CURSOR;
    end;
    or replace this procedure with another method to return data and use in a .NET application.

    961449 wrote:
    There are so any solution to access TestPACKAGE. DOWNLOAD_CURSOR to .NET web application. I found how to access a stored procedure that returns a ref cursor
    And the package cannot be change, add a stored procedure that returns a ref cursor

    In this case, it is not possible. Your .NET code cannot directly access the static cursor declaration, because at this point it's just a statement, not an open cursor.
    Cursors declared that are opened using the PL/SQL code, using the OPEN cursor_name statement or variable IN the syntax of other cases.
    .NET and other external applications require a ref Cursor, so the only way you can get this query in a Ref cursor is to open the ref cursor in the query itself.
