Executing A Stored Function

I created the function below to generate four random number and to have them inserted into a table called RANNUMBERS.
CREATE OR REPLACE FUNCTION randnumber RETURN NUMBER IS
BEGIN
declare
i number;
inivar_v number;
     rannumb      number;
multi_v1 number;
addm_v number;
inicon_v number;
duocon_v number;
divisor_v number;
begin
i := 1;
inivar_v := 3;
inicon_v := 4;
duocon_v := 1;
divisor_v := 9;
loop
multi_v1 := inicon_v * inivar_v;
addm_v := multi_v1 + duocon_v;
rannumb := mod(addm_v,divisor_v);
insert into rannumbers values ('rannumb');
i := i+1;
inivar_v := rannumb;
exit when i > 4;
end loop;
return rannumb;
end;
COMMIT;
END;
I then run the script in sql* Plus and the result I had was:
Function Created.
I checked the table to see if the four random numbers had been inserted but alas the table was empty. I then realized the function had not been invoked or executed. But, how do I execute a fuction? Could someone please help.

Why can't you use the package 'DBMS_RANDOM' to generate random numbers?

  • Execute a stored function from command line

    Hello,
    I have a db stored function and I need to execute it from command line. I've tried by this way:
    (I need to connect with sys credentials)
    sqlplus sys/mypwd@mydb AS SYSDBA @myfile.sql
    and myfile.sql is:
    exec myschema.sf_test;
    but I get this error:

    You can use exec command for the execution of a procedure with out bind variable, but for a function always use bind variable.
    Function should return a value, so you must have to assign the function return value to a variable.
    like given below(or simply query the function using select statement)

  • Executing stored function using Native SQL

    In SAP documentation, I can see how to execute an Oracle stored procedure in an external database using:
    EXEC SQL.
      EXECUTE PROCEDURE procname
    ENDEXEC.
    I want to execute a stored FUNCTION within a package.  I have tried executing it using the syntax for PROCEDURE above and get a "ORA-06550 wrong type or number of arguments" error.  Since the function has one argument in and one argument out, I think I am counting the number of arguments correctly.  Has anyone executed from within ABAP an Oracle function stored in an external database?
    Thanks

    Janice - from help.sap.com:
    Stored Procedures
    The command EXECUTE PROCEDURE proc allows you to call a procedure stored in the database. When you call it, you can pass a list of host variables as parameters. When yuo call a procedure, you must specify for each parameter whether it is an input parameter ( IN), output parameter (OUT) or changing parameter (INOUT).
    Example
    Calling a Procedure:
    DATA Y TYPE I VALUE 300.
    DATA Z TYPE I.
    EXEC SQL.
    INSERT INTO AVERI_CLNT (CLIENT, ARG1, ARG2, ARG3)
    VALUES ('000', 9, 2, 47)
    ENDEXEC.
    EXEC SQL.
    CREATE OR REPLACE PROCEDURE PROC1 (X IN NUMBER) IS
    BEGIN
    UPDATE AVERI_CLNT SET ARG3 = ARG3 + X;
    END;
    ENDEXEC.
    EXEC SQL.
    CREATE OR REPLACE PROCEDURE PROC2 (X IN NUMBER, Y OUT NUMBER) IS
    BEGIN
    SELECT ARG3 INTO Y
    FROM AVERI_CLNT
    WHERE CLIENT = '000' AND ARG1 = 9 AND ARG2 = 2;
    UPDATE AVERI_CLNT SET ARG3 = ARG3 - X;
    END;
    ENDEXEC.
    EXEC SQL.
    EXECUTE PROCEDURE PROC1 ( IN :Y )
    ENDEXEC.
    EXEC SQL.
    EXECUTE PROCEDURE PROC2 ( IN :Y, OUT :Z )
    ENDEXEC.
    IF SY-SUBRC <> 0 OR Z <> 347.
    WRITE: / 'Wrong result for EXECUTE PROCEDURE:', Z.
    ENDIF.
    EXEC SQL.
    DROP PROCEDURE PROC1
    ENDEXEC.
    EXEC SQL.

    Iam using PowerBuilder 8 as a FRONT END Tool ( connecting to ORACLE db - 10gR2 through ODBC driver) for executing the above function where i will pass the stored procedure name ( CONCATNAME ) as an argument.
    The function is executing fine when i execute through ISQL interface.
    While executing this function from the front end tool( POWER BUILDER ) iam getting the following error.
    ORA-03113: end-of-file on communication channel.
    I dont know, why this error is coming ? As the function is executing fine
    through ISQL ?
    I think this error will come if you execute the above function from any front
    end tool( like .Net etc. ).
    Can anybody help me ? How to avoid this error ( ORA-03113 ) ?
    For Your Information: All other simple functions are executing fine through POWER BUILDER in my application.

    ORA-03113: end-of-file on communication channel is a client driver error. It is a symptom of a problem - it is not the problem itself.
    This error message simply says that your client was still talking to the database service process servicing your client session, when that (TCP/IP socket) connection was unexpectedly torn down by the server.
    This is often caused by that database service process crashing due to an internal (ORA-0600) error - and taking the TCP/IP connection down with it.
    You need to ask your DBA to have a look at the alert log file for the Oracle instance. The crash will be recorded there. In addition a trace file should have been created.
    Using the 1st parameter of the ORA-0600 message for the crash in the alert log file, the DBA should lookup the possible causes of the crash on Metalink note 153788.1

  • Incorrect Update Count by executing a stored procedure from Java

    Hi Guys,
    I am calling a stored procedure from the java program which is modifying the rows of a table. Now I want to know how many rows have been modified by executing the stored procedure. I am writing the following code for the purpose:
    OracleCallableStatement stmt =
    (oracle.jdbc.driver.OracleCallableStatement)con.prepareCall("{callsp_um_setForumID(?,?)}");
    stmt.setInt(1,101);
    stmt.setInt(2,666);
    n = stmt.executeUpdate();
    System.out.println(n + " row(s) updated");
    This procedure is actually modifying the table(When I query the databse it has modified 1 row). But it is returning a value 0 and is printing "0 row(s) updated".
    Is there a way by which I can find out the number of rows updated by executing the stored procedure?
    Thanks

    I'm no expert on this, but I have a similar call where I fetch
    an Oracle REF CURSOR from a call to a stored function. If you
    fetch the cursor as an Object from your CallableStatement, you
    can then cast it to a ResultSet e.g.
    mystatement.executeUpdate();
    ResultSet rs = (ResultSet) mystatement.getObject(1);
    Then you should be able to loop through your ResultSet as usual.
    Good luck!

    If you want to return a result set (result of a query) from
    your PL/SQL, you will have to do what Daverms suggested and convert
    your function to a procedure
    and use a reference cursor to return your result set. Your
    procedure will have to be contained in a package in order for you
    to declare a ref cursor "globally" so that it can be accessed by
    CF.
    Oh, and be sure to change your cfstoredproc procedure
    parameter to add the package name to the proc name.
    <cfstoredproc procedure="your_pkg.GetAction"
    datasource="test_DSN">

  • Execute oracle stored procedure from C# always returns null

    Hi,
    I'm trying to execute a stored procedure on oracle 9i. I'm using .Net OracleClient provider.
    Apparently, I can execute the stored procedure, but it always returns null as a result (actually all the sp's I have there returns null)! I can execute any text statement against the database successfully, and also I can execute the stored procedure using Toad.
    This is not the first time for me to call an oracle stored procedure, but this really is giving me a hard time! Can anyone help please?
    Below are the SP, and the code used from .Net to call it, if that can help.
    Oracle SP:
    CREATE OR REPLACE PROCEDURE APIECARE.CHECK_EXISTENCE(l_number IN NUMBER) AS
    v_status VARCHAR2(5) := NULL;
    BEGIN
    BEGIN
    SELECT CHECK_NO_EXISTENCE(to_char(l_number))
    INTO v_status
    FROM DUAL;
    EXCEPTION WHEN OTHERS THEN
    v_status := NULL;
    END;
    DBMS_OUTPUT.PUT_LINE(v_status);
    END CHECK_CONTRNO_EXISTENCE;
    C# Code:
    string connStr = "Data Source=datasource;Persist Security Info=True;User ID=user;Password=pass;Unicode=True";
    OracleConnection conn = new OracleConnection(connStr);
    OracleParameter param1 = new OracleParameter();
    param1.ParameterName = "v_status";
    param1.OracleType = OracleType.VarChar;
    param1.Size = 5;
    param1.Direction = ParameterDirection.Input;
    OracleParameter param2 = new OracleParameter();
    param2.ParameterName = "l_number";
    param2.OracleType = OracleType.Number;
    param2.Direction = ParameterDirection.Input;
    param2.Value = 006550249;
    OracleParameter[] oraParams = new OracleParameter[] { param1, param2 };
    OracleCommand cmd = new OracleCommand("CHECK_EXISTENCE", conn);
    cmd.CommandType = CommandType.StoredProcedure;
    cmd.Parameters.AddRange(oraParams);
    conn.Open();
    object result = cmd.ExecuteScalar();
    conn.Close();

    Hi,
    Does that actually execute? You're passing two parameters to a procedure that only takews 1 and get no error?
    Your stored procedure doesnt return anything and has no output parameters, what are you expecting to be returned exactly?
    If you're trying to access V_STATUS you'll need to declare that as either an output parameter of the procedure, or return value of the function, and also access it via accessing Param.Value, not as the result of ExecuteScalar.
    See if this helps.
    Cheers,

    I have tried various combinations but it always have same complaint.
    Thanks in advance for help.

    Hello,
    It is complaining because the DatabasePlatform being used doesn't support functions. So the problem is that it is using the DatabasePlatform instead of the Oracle10Platform that you are expecting. How have you defined it? Could you have multiple sessions.xml files, and the one that is being picked not define the Oracle10Platform? Or could you be overriding the login somehow (prelogin event etc) and setting it to use the default DatabasePlatform by accident?

    Chris

  • Stored function not returning result set unless recompiled

    Hi,
    I have a strange situation going on with a basic Java (1.6.0.17) application talking to an Oracle 11g (11.2.0.1.0) database. Basically what is happening is that sometimes a stored function's return value (a result set) is not making it as far as JDBC/Java, unless I recompile the stored function (with absolutely no changes to the application or function's code). I am always able to successfully see the result set if I call the function directly from within SQL Developer, just not on the Java app/JDBC side.
    I've tried running with 3 different physical Oracle 11g servers and tried running the app on a couple of machines. I'm wondering if this is either some kind of caching issue or perhaps a JDBC bug/misconfiguration.
    Any help would be greatly appreciated. Attached to this message:
    1. stored function code
    2. snippet of Java app code
    3. ODBC trace output when returned a empty result set (ie failure scenario)
    4. ODBC trace out when returned the correct result set (ie success scenario)

    ** as they're large I've just extracted the sections that had differences. Leave a message here and I can send you the full ones if necessary.

  • Cannot call ANY stored functions from my Java program

    My problem is that I cannot call ANY stored procedure from my Java
    program. Here is the code for one of my stored procedures which runs
    very well in PL/SQL:
    PL/SQL code:
    CREATE OR REPLACE PACKAGE types AS
    TYPE cursorType IS REF CURSOR;
    END;
    CREATE OR REPLACE FUNCTION list_recs (id IN NUMBER)
    RETURN types.cursorType IS tracks_cursor types.cursorType;
    BEGIN
    OPEN tracks_cursor FOR
    SELECT * FROM accounts1
    WHERE id = row_number;
    RETURN tracks_cursor;
    END;
    variable c refcursor
    exec :c := list_recs(11)
    SQL> print c
    COLUMN1 A1 ROW_NUMBER
    rec_11 jacob 11
    rec_12 jacob 11
    rec_13 jacob 11
    rec_14 jacob 11
    rec_15 jacob 11
    Here is my Java code:
    import java.sql.*;
    import java.io.*;
    import oracle.jdbc.driver.*;
    class list_recs
    public static void main(String args[]) throws SQLException,
    IOException
    String query;
    CallableStatement cstmt = null;
    ResultSet cursor;
    // input parameters for the stored function
    String user_name = "jacob";
    // user name and password
    String user = "jnikom";
    String pass = "jnikom";
    DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
    try { Class.forName ("oracle.jdbc.driver.OracleDriver"); }
    catch (ClassNotFoundException e)
    { System.out.println("Could not load driver"); }
    Connection conn =
    DriverManager.getConnection (
    "jdbc:oracle:thin:@10.52.0.25:1521:bosdev",user,pass);
    try
    String sql = "{ ? = call list_recs(?) }";
    cstmt = conn.prepareCall(sql);
    // Use OracleTypes.CURSOR as the OUT parameter type
    cstmt.registerOutParameter(1, OracleTypes.CURSOR);
    String id = "11";
    cstmt.setInt(2, Integer.parseInt(id));
    // Execute the function and get the return object from the call
    cstmt.executeQuery();
    ResultSet rset = (ResultSet) cstmt.getObject(1);
    while (rset.next())
    System.out.print(rset.getString(1) + " ");
    System.out.print(rset.getString(2) + " ");
    System.out.println(rset.getString(3) + " ");
    catch (SQLException e)
    System.out.println("Could not call stored function");
    e.printStackTrace();
    return;
    finally
    cstmt.close();
    conn.close();
    System.out.println("Stored function was called");
    Here is how I run it, using Win2K and Oracle9 on Solaris:
    C:\Jacob\Work\Java\Test\Vaultus\Oracle9i\FunctionReturnsResultset>java

    Any help is greatly appreciated,
    Jacob Nikom

    Thank you for your suggestion.
    I tried it, but got the same result. I think the difference in the syntax is due to the Oracle versus SQL92 standard
    conformance. Your statament is the Oracle version and mine is the SQL92. I think both statements are acceptable
    by the Oracle.

  • Why returning string from java stored function failed ?  HELP ME, PLEASE

    Hi everybody,
    I created java stored function: it's doing http post, parsing xml from http reply, and returning string result.
    Sometimes, it doesn't return any value. What can be a reason ?
    The high level procedure, has following form:
    class SBE {
    public static String call(String arg0) {
    SBE sbe=new SBE("d:\\oracle\\ora81\\network\\log\\SBE.log");
    String result=SBEParser.go(sbe.sendRequest(arg0, ""), sbe.logger);
    sbe.logger.log(result);
    sbe.logger.log("Finish SBE intetraction");
    return result;
    PLSQL wrapper has a simple form:
    create or replace package PG_SBE as
    function CALL(arg0 in varchar2) return varchar2;
    end;
    create or replace package body PG_SBE as
    function CALL(arg0 varchar2) return varchar2 as language java name 'SBE.call(java.lang.String) return java.lang.String';
    end;
    In log file ("d:\\oracle\\ora81\\network\\log\\SBE.log"), I can find message :
    "Finish SBE intetraction"
    but query:
    select pg_sbe.call("any argument") from dual;
    doesn't finish.
    What can be a reason ? What can I do to trace stage of convertion java string to varchar ?
    Please help me...
    Best regards
    Marek

    Maybe your call is wrong... Shouldn't there be a "?" instead of "1"?
    Your code:
    String myquery = "begin :1 := jspTest; end;";
    I provide my (working) call from java as an example. Maybe it is of any help... :)
    import java.sql.*;
    import oracle.jdbc.driver.*;
    public Vector getAllHosts() throws SQLException {
    //return getHosts(false, -1);
    Connection conn = null;
    CallableStatement cs = null;
    Vector hostV = new Vector();
    try {
    conn = getConnection();
    String query = "{ ? = call curTestPkg.curTestFunc}";
    cs = conn.prepareCall(query);
    cs.registerOutParameter(1, OracleTypes.CURSOR);
    cs.execute();
    ResultSet rs = ((OracleCallableStatement)cs).getCursor(1);
    while (rs.next()) {
    Host host = new Host(
    rs.getInt("hostid")
    , rs.getString("name")
    , rs.getString("descr")
    , rs.getString("os"));
    hostV.add(host);
    cs.close();
    return hostV;
    } finally {
    close(conn, cs);

    hi Stefan thanx.....even after changing the call statement i get the same error. i changed query string as...
    String myquery = "{ ? = call jspTest}";
    CallableStatement cst = con.prepareCall(myquery);

    PS : THIS IS THE FIRST TIME I AM WORKING WITH PL/SQL AND IT IS URGENT

  • Named parameters in stored function

    Hi,
    I am trying to execute stored function from java in oracle . I am using Oracle 9.2.0.1.0 and the newest JDBC drivers, ie. for 10g which are compatible. I have flicked through JDBC Named Parameters example but it only addresses stored procedures.
    The problem I have is that I do not know what name the return value of stored procedure has.
    stored function parameter names:
    1. ????
    2. test1 Mode: IN
    3. test2 Mode: IN
    ?=call test_function(?,?);
    When I am trying to set values as indexes everything works perfect.
    CallableStatement cs = .....
    cs.registerOutParameter(1, Types.VARCHAR);
    cs.setString(2, "a");
    cs.setString(3, "b");
    cs.execute();
    String returnedValue = cs.getString(1);
    However, when I am trying to use named parameters the code looks like this:
    CallableStatement cs = .....
    cs.registerOutParameter(1, TYPES.VARCHAR);
    cs.setString("test1", "a");
    cs.setString("test2", "b");
    and the question is what is the name of return parameter.
    I have tried to put the same name as the name of stored function but is reports error.
    Instead I had to first getmetadata from oracle and in case of stored functions utilize it, unfortunatelly getting metadata has perfomance issues and I heard that oracle 10g is even slower in getting metadata.
    If anyone knows the answer to my question, please answer.

    I have the Motorola Surfboard SBG900, but was wondering if there are newer (and better) combo cable modem/wireless routers now available. Also, is cable still much faster than DSL, and, if not, are there good combined modem/routers for DSL? Thanks.
