• A simple stored procedure - select with an if statement returning a cursor

  Hello

  I am creating a simple stored procedure, but having never worked with them, before that I'm not sure what I'm doing wrong.

  Here is my code:

  create or replace
  procedure contact_return(
      v_contact_id IN varchar2,
      p_cursor OUT SYS_REFCURSOR)
  AS
  begin
  
    set sql_statement varchar2(4000) := '
      SELECT URN,
        FIRSTNAME,
        LASTNAME,
        TITLE,
        CREATED_DT,
        AREA_URN,
        MOBILE,
        WORK,
        EMAIL,
        ORG_NAME,
        ADDRESS,
        POSTCODE,
        IN_USE
      FROM CONTACT';
      
    if v_contact_id is not null then
      sql_statement := sql_statement || ' where urn = ' || v_contact_id;
    end if;
    
    open p_cursor for sql_statement;
  end;
  

  It is actually 2 errors:

  • Error (7.3): PL/SQL: statement ignored
  • Error (7.7): PL/SQL: ORA-00922: missing or invalid option

  That seems to be a problem with my line fixed sql_statement, but it looks good for me?

  Thank you

  Do not know what language you are trying to use there for your variable declarations, but it is not PL/SQL.  Looks like you're mixing SQL * more syntax with PL/SQL UltraLite or something.

  Something more in this sense is perhaps what you are looking for...

  create or replace procedure contact_return (v_contact_id IN varchar2

  p_cursor ON SYS_REFCURSOR

  ) AS

  sql_statement varchar2 (4000): = '

  SELECT THE URN,

  FIRST NAME,

  LASTNAME,

  TITLE,

  CREATED_DT,

  AREA_URN,

  MOBILE,

  WORK,

  E-mail

  NOM_ORG,

  ADDRESS,

  Zip code

  IN_USE

  CONTACT

  where urn = nvl(:1,urn)';

  Start

  Open the p_cursor for sql_statement using v_contact_id;

  end;

• 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.

• Understanding stored procedures

  Hello

  Oracle 11.2.0.0.2

  I am trying to learn how stored procedures to use them later in the future web applications.  I was going through some documentation and found a simple stored procedure and I just wanted to see if someone could help to clarify if I understand how this stored procedure is supposed to work.

  TRIGGER XXX_TEST CREATE create a trigger with the name of XXX_TEST

  BEFORE INSERT Execute the trigger before it runs the command INSERT

  ON f.w5 FOR EACH ROW, do something "for each line' which is 'on' the table w5 belonged f schema

  START the starting point of the orders which will take place within this block

  Select count (1) IN the rt of 1934_e.doc where: new. U0 = docnum and 'AA' = a1 and a2 = 'DR' and a3! = « Z »)) ; Select all the records and put new 'in' the variable doc table belonging to f, where rt. U0 variable equals the docnum and column a1 is equal to 'AA' and column a2 is equal to 'DR' and a3 is not equal to 'Z'

  IF rt > 0 THEN conditional statement, if the rt variable is greater than 0, then below that

  : new.pt: = 9 | substr (PT 2);  concatenation of the variable which is set to match the 9

  : new. U1: = 'UNFAIR ';  sets the variable: new. U1: equal to 'EVIL'

  END IF;  end of the conditional statement

  delete from f.w5 where substr (pt, 1, 1) = 9 and U1 = "UNFAIR."  delete records from table w5 belonged to f where substring value 9 starting at position 1 with a length of 1 is equal to 9 and U1 is equal to 'FALSE'

  END;  the point of arrival of the "BEGIN"

  The part that I'm not sure of is the IF / END IF block.  I read that the | means the concatenation, but I don't really know what or why it is concatenation.  Another explanation is appreciated!  Thank you.

  Hello

  You have understood about correctly.

  There are many errors in this code.  For example, he referred to the local variables, rt and pt, but these variables are not defined anywhere.  For example, in the assignment you intrigued plus:

  : new.pt: = 9 | substr (PT 2);

  : NEW.pt initially made reference (rightly) of a column in the current insertion, but pt near the end line (without: NEW.) reference a local variable and I do not see where all the local variables are currently reported.  Perhaps the one who wrote this means use; NEW.pt in both places.

  SUBSTR (pt, 2)

  means the part of string pt starting with his 2nd character, so

  '9' || SUBSTR (pt, 2)

  a copy of the pt, but with its first character replaced by "9".

  Why the trigger would do this?  Your guess is as good as mine.  Apparently, the pt of the column is a kind of code, and the first character of the code is supposed to be "9" If there is no line in the table corresponding to the column of u0, doc and met certain other conditions, at the point where this line was inserted.

  (The | operator expected strings before and after it.)  If you use a NUMBER, such as 9, in a place where one expects a string, such as '9', Oracle will automatically convert the NUMBER to a string, but it is advisable to use the correct data in type.)

  Moreover, another error in this trigger is that he tries to DELETE rows from the same table that is based on.  A FOR EACH ROW trigger on tble f.w5 can't even read other f.w5 lines, let alone delete them.

• 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

    ;
    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,

  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)

• helps the stored procedure

  Hi all
  I am creating a simple stored procedure that updates a table which has initially been removed
  
  CREATE PROCEDURE CLASSTEST_01 IS
  BEGIN
  
  delete from temp_test_01;
  
  Select * from TEMP_CLASS_SCORE in temp_test_01;
  END CLASSTEST_01;
  
  However, it will not create.
  Pls can someone check if there is something wrong with the statement
  Thank you

  There is no need of stored procedure. All you need is:

  delete from temp_test_01;
  insert into temp_test_01 select * from TEMP_CLASS_SCORE;
  

  Or:

  truncate table temp_test_01;
  insert into temp_test_01 select * from TEMP_CLASS_SCORE;
  

  But if you decide to create one:

  CREATE OR REPLACE
    PROCEDURE CLASSTEST_01
      IS
      BEGIN
          delete from temp_test_01;
          insert into temp_test_01 select * from TEMP_CLASS_SCORE;
  END CLASSTEST_01;

• call a stored procedure with OUT VARCHAR2 parameter fails

  Hi all
  
  I use the Oracle 11.2.0.1 version OLE DB provider. I have a simple stored procedure that contains a VARCHAR2 OUT parameter:
  
  create or replace procedure TestOut (RESULT_CODE OUT VARCHAR2) is
  Start
  RESULT_CODE: = 'X '.
  TestOut end;
  
  The following c# code piece fails:
  
  String ConnStr = "Provider = OraOLEDB.Oracle; User ID = test; Password = test; Data Source = sandbox; « ;
  OleDbConnection Conn = new OleDbConnection (ConnStr);
  Conn.Open ();
  OleDbCommand Cmd new OleDbCommand();
  Cmd.Connection = Conn;
  OleDbParameter Param = Cmd.CreateParameter ();
  Param.ParameterName = "RESULT_CODE ';
  Param.Direction = System.Data.ParameterDirection.Output;
  Param.OleDbType = OleDbType.BSTR;
  Param.Size = 1;
  Cmd.Parameters.Add (Param);
  
  Cmd.CommandType = System.Data.CommandType.Text.
  Cmd.CommandText = "{TESTOUT (?). CALL} ";
  Cmd.ExecuteNonQuery ();
  
  If the stored procedure is modified to contain an OUT parameter, the same code works, after you change the type of parameter to appropriate OleDBType (OleDbType.SmallInt).
  
  What am I doing wrong when handling OUTPUT VARCHAR parameters? Y at - there any limitation on the types of parameters stored procedure using the Oracle OleDB provider?
  
  Published by: user957565 on 1/Ago/2011 06:31

  I get an access violation, using 11202. What do you get?

  In any case, it works fine for me using OleDbType.VarChar instead of OleDbType.BSTR.

  Hope this helps, comments welcome.

• How to call a stored procedure with a REF CURSOR output parameter

  I'm looking forward to example calling a function/stored procedure with a REF CURSOR output parameter and get the result.
  In other words, I have a stored function/procedure that runs a SELECT statement using the OCI library and then he could get the values of each row and each column.
  
  I put a code snippet, it have only the main thing to call a simple stored procedure and to print the name of each column of the cursor, but I couldn t to print out values in the table that calls the stored procedure.
  I understand that the next step is to call an OCIStmtFetch.
  How to associate the slider with the OCIStmtFetch?
  
  If you need more information, just tell me.
  
  I use ANSI C with HP - UX (HP - UX C) operating system and Oracle 10 g.
  
  
  Kind regards.

  Hi Antonio,.

  I see this:

  c_buf=(ub1 **)calloc(sizeof(ub1 *),3);
  
  ...
  
  rc=OCIDefineByPos(pOciStatCursor,&pdef,(OCIError *)pOciError,pos,c_buf[pos-1],size+1,(ub2)type,(dvoid *)c_indp[pos-1],(ub2 *)0,(ub2 *)0,OCI_DEFAULT);
  

  That I don't understand. You allocate space for 3 pointers ub1 but I don't see where these pointers are then initialized to point to where the data is to be stored.

  I do not read correctly?

  Sorry for posting code long, but here is an example of code that I have. It is much more 'code' for your code, but maybe that will be enough...

  NOTE: This is just the code example and not rigorous. For example, I don't check the memory, allocations etc in this code!

  Kind regards

• Simple question-how to call a stored procedure or function of apex?

  Simple question-how to call a stored procedure or function of apex?
  Thanks advance.
  Doug

  Hi Doug,.
  You can call a procedure or function of apex. It depends on what you want to do with the function or procedure. If you want to retrieve table data in a specific area, you can try something like this-

  The following statement creates the function get_bal on the oe.orders of sample table (PL/SQL is in italics):

  CREATE FUNCTION get_bal (acc_no in NUMBER)
  RETURN NUMBER
  IS acc_bal NUMBER (11.2);
  BEGIN
  SELECT order_total
  IN acc_bal
  Orders
  WHERE customer_id = acc_no;
  Return (acc_bal);
  END;
  /

  The function created in the previous example can be used in a SQL statement. For example:

  SELECT get_bal (165) FROM DUAL;

  GET_BAL (165)
  ------------

  hope this will help,

• SQL stored procedure input and output parameters

  Hello Gang,

  My dead end trying to call a stored procedure in SQL Server 2008 with the LV database tool.

  for purposes of experimentation, I've created a small procedure with an input parameter that returns an integer as return value.  It works describing a query, but all attempts at LV produce an error-2147217900 when executing query VI.  I did find examples of that.

  Sending a bunch of parameters to a stored procedure and checking the value of return seems to be pretty common stuff.

  I'll appreciate any help.

  Thank you

  Roger

  Hi Roger,

  There are a few prerequisites which I will list below. If you have not checked these things, so don't hesitate, as your hiccups can be there.

  Prerequisites:

  1. Ensure that you can read from a table in the database to verify that you can access the database (user permissions) and ensure that your login details are correct. Among other things, make sure that the. DSN switches to the correct database. (See the simple example below, SQL Select.vi)
     
  2. Make sure that your user (if you use SQL authentication) has permissions to run the STORED procedure by running the procedure in SQL Server Management Studio (you seem to have already done this)

  Example by calling a procedure without parameters (attached as SPROC_No_Parameters.vi):

  

  Example by calling a procedure with parameters (attached as SPROC_Parameters.vi):

  

  An article on the execution of stored procedures is here:

  http://digital.NI.com/public.nsf/allkb/07FD130746083E0686257300006326C4

  Don't forget to download the example VI since it includes the cases where you want an output parameter of the procedure rather than a table.

  I tested these against two very simple SPROCs and it worked fine (on SQL Server 2005, but 2008 should be the same).  Stored procedures have been:

  CREATE PROCEDURE [dbo]. [GetContacts]

  AS
  BEGIN
  -SET NOCOUNT ON added to avoid additional results sets from
  -interfering with SELECT statements.
  SET NOCOUNT ON;

  -Controls insert for procedure here
  SELECT * FROM Contacts
  END

  and

  CREATE PROCEDURE [dbo]. [MultiplyAges]
  @param1 INT = 1
  AS
  BEGIN
  -SET NOCOUNT ON added to avoid additional results sets from
  -interfering with SELECT statements.
  SET NOCOUNT ON;

  -Controls insert for procedure here
  SELECT (age * @param1) OF Contacts
  END

  I would like to know if these examples work for you or if you have any other questions.  Don't forget to go through this KB article and articles related to it, they should cover other situations.

• Y at - it a syntax better/more runs to get data to and from stored procedures?

  To test the stored procedure call, I created a simple package

  create or replace package TEST_PROCEDURES as
  
  procedure Test1 (
     arg1 in number,
     arg2 in number,
  
     res1 out number,
     res2 out number);
  
  end;
  
  

  and a page with fields number four (P1_INPUT_2, P1_OUTPUT_1, P1_INPUT_1, P1_OUTPUT_2) and a button excuting the code following PL/SQL:

  declare
    arg1 integer;
    arg2 integer;
    res1 integer;
    res2 integer;
  begin
    arg1 := :P1_INPUT_1;
    arg2 := :P1_INPUT_2;
  
    TEST_PROCEDURES.Test1(arg1, arg2,
                          res1, res2);
                      
    APEX_UTIL.SET_SESSION_STATE('P1_OUTPUT_1', res1);
    APEX_UTIL.SET_SESSION_STATE('P1_OUTPUT_2', res2);
  end;
  
  

  It works, but it looks like a lot of unnecessary code to me. Any suggestions?

  end;

  It works, but it looks like a lot of unnecessary code to me. Any suggestions?

  Why would you do that? APEX may be referenced in the same way as all the other bind variables (although it is worth noting that their type is always VARCHAR2, so in this case, it will rely on the implicit conversion):

  begin
    test_procedures.test1(:p1_input_1, :p1_input_2, :p1_output_1, :p1_output_2);
  end;

• Logic of tip insert - using a stored procedure?

  Here's my use case:

  • I have a table called TAGS that has two columns: id (number key, primary) and text (string)
  • the table has a constraint of database set that each text must be unique
  • the table also has a fixed sequence back next id available
  • I created an entity of the DB object and its default View object
  • I also created a page where I display a table read-only based on the View object
  • Finally, I added a text field and a button to the page
  • What I want to achieve is to insert all tags entered in the entry in the table fields, when the button is clicked. Note, however, that the entry field is a comma-separated list of tags, moreover, I have to insert only those tags that are new (to respect the constraint of database), and finally, I would like to use the sequence in insert or orders. Once completed, the page should also be updated.

  My first question is whether a stored procedure is the right way to perform such a step insert logical. If not, what other means must be used in the ADF.

  My second question is to know how to call the stored procedure and pass it the value of the input as a parameter field. I found this article http://andrejusb.blogspot.cz/2011/04/invoking-stored-procedures-and.html, but miss me a few transition points:

  1. How the callGreetingsFunction method call (I just get it that it's a method of the EO generated Java class?) after that the button is clicked?
  2. How to pass the value of the input field in this method as a parameter?

  Thanks in advance for your help.

  Now, what happens if I run it like this:

  A. the procedure is executed after a click on the button

  (B) the page is not updated (I had to do the research to get the new lines are visible in the table)

  C. the constraint is ignored (after discounting there were several lines with unique identification number, but pr is - empty)

  D. nothing has been committed to the database - if I closed the application window and it start again, the lines have disappeared from the table, but addition of new lines used number of increased seq

  E. Similarly, if I did directly inserts into the database, these lines did not appear until I transferred the application

  B. told it page to refresh. And that's usually enough to refresh your ViewObject with: viewObject.executeQuery)

  C. Si the constraint is not enforced for null values. And this has nothing to do with the adf, this is related to oracle db.

  D. you're calling commit.

  E. you must re-run your view object (viewObject.executeQuery ())

  Nevertheless, here is my rookie questions:

  There there a simple way to refresh the page (or just the table containing the data)?

  -How to validate changes (immediately after execution of the procedure)?

  -How is the constraint has been ignored? I am sure it would fail on validation, but I thought that it will be considered even for adding data to the table.

  -Are there a way to update the original Version of the database every time that the page is opened or refreshed?

  -Drag and drop operation Execute like button on your page (or call vo.executeQuery () by program)

  -Drag and drop the operation of posting as a button on your page (or invoke it by programming on the DBTransaction object)

  -ignored for what values? for null values? It is expected, because each null is "unique."

  -Yes, but you probably shouldn't do that for performance reasons, see this: Andrejus Baranovskis Blog: Cache results for ADF iterator property

• To proceed if a condition is fulfilled in a stored procedure

  Hello Experts,

  I have a fairly simple requirement and I was not able to solve, I hope someone could help me with this.

  I have an existing stored procedure that captures data in a cursor and writes it to a file using the UTL utilities. It works very well. I want to add a condition before the cursor, if this condition is met, it must proceed to the cursor and write the file, otherwise it's just not the procedure with an error message saying the unmet condition. I'm doing something wrong here, can someone please fix the part of the State. I think I could use 'IF EXISTS'. Please notify. Thank you in advance.

  This is the model,

  CREATE OR REPLACE PROCEDURE < PROC >

  as

  Define variables

  n_cnt number: = 0;

  ...

  ...

  ..

  -Here is the condition I want to go far from other I want to fail the procedure-

  BEGIN

  SELECT COUNT (TABLE_NAME) made a MISTAKE in n_cnt

  EXTRACT

  WHERE

  AND STATE = 'error ';

  IF n_cnt <>0 THEN go - continue the procedure -

  END else fail PROCEDURE - the procedure-

  -Creates a cursor/temp table that contains the data to be processed at line by line, which is used to write to a file

  <>SLIDER

  IS

  -Home select query starts here.

  SELECT DISTINCT FIRSTNAME

  LASTNAME

  NAMES

  ;

  BEGIN

  UTL_FILE. PUTF (v_FILE_HANDLE, '% s%s\n',

  'FIRST NAME' |' | ',

  "LASTNAME");

  CURSOR OPEN.

  -Get the cursor in the temporary folder

  CURSOR FETCH IN REC.

  CURSOR % WHILE

  -Using the loop to load data

  LOOP

  -Using the UTL package to write to a file

  UTL_FILE. PUTF (v_FILE_HANDLE, '% s%s\n',

  RECOMM. FIRSTNAME |' | ',

  RECOMM. LASTNAME );

  end loop;

  END '

  Hello

  You can do the following.

  IF n_cnt = 0 THEN

  RAISE_APPLICATION_ERROR (-20001, 'condition not met');

  END IF;

• disconnected rowset select CachedRowSet of a statement within the stored procedure?

  Hello everyone

  I'm using CachedRowSet returned from a parameterized select statement and it works very well.

  If I put the same select statement in a simple read only then stored procedure I get this exception: "a result set has been generated for the update.

  I'm not trying to update all lines in my code.

  I tried to make the CachedRowSet to be read-only, but this does not help, same error.

  Question 1: a stored procedure returns a single result set can be called to fill a CachedRowSet read-only? (in a similar way to a method of CallableStatement prepareCall with input/output settings).

  Question 2: in general is something to be encouraged for future development or are they deprecated or replaced with something else or better using CachedRowSet, FilteredRowSet (disconnected) and WebRowSet, JDBCRowSet (connected)?

  Thank you very much in advance

  It work? (be sure that your stored procedure done * nothing * before running this query)

  PreparedStatement p = conn.prepareStatement ("{call dbo.p_testCachedJDBCRowSet (?)}" ");

  p.setInt (1, 10);

  CRS CachedRowSetImpl = new CachedRowSetImpl();

  CRS. Populate (p.ExecuteQuery ());

• Re: "insufficient privileges" error when you run the Java stored procedure in another schema

  I get an "insufficient privileges" error when you run the Java stored procedure in another schema, see details below.  I don't know what are missing privileges (I already granted the EXECUTE privilege), suggestions?  -Thank you.

  Define a simple java class and deploy it as a Java stored procedure to test:

  
  

  Schema: User1

  test of the package;

  public class HelloWorld {}

  public HelloWorld() {

  Super();

  }

  public static String Hello () {}

  Return "HELLO";

  }

  }

  CREATE or REPLACE FUNCTION HELLO RETURN VARCHAR2 AUTHID CURRENT_USER AS LANGUAGE JAVA NAME ' test. HelloWorld.hello () return java.lang.String';

  Grant execute on USER2 HELLO

  Test the Java stored procedure through the PL/SQL function call (in the same schema):

  
  

  Schema: User1

  SET SERVEROUTPUT ON

  DECLARE

  v_Return VARCHAR2 (200);

  BEGIN

  v_Return: = User1. HELLO;

  DBMS_OUTPUT. Put_line ('v_Return =' | v_Return);

  END;

  anonymous block filled

  v_Return = HELLO

  Test the Java stored procedure through the PL/SQL function call in a different pattern:

  
  

  Schema: USER2

  SET SERVEROUTPUT ON

  DECLARE

  v_Return VARCHAR2 (200);

  BEGIN

  v_Return: = User1. HELLO;

  DBMS_OUTPUT. Put_line ('v_Return =' | v_Return);

  END;

  Error report-

  ORA-01031: insufficient privileges

  ORA-06512: at "User1." HELLO', line 1

  ORA-06512: at line 4 level

  01031 00000 - "insufficient privileges".

  * Cause: An attempt was made to change the user name or password

  without the privilege appropriate. This error also occurs if

  trying to install a database without the need for employment

  access privileges.

  When Trusted Oracle is configure in DBMS MAC, this error may occur

  If the user has been granted the privilege necessary for a higher label

  that the connection is active.

  * Action: Ask the database to perform the operation or grant administrator

  the required privileges.

  For users Trusted Oracle get this error, well that granted the

  the privilege that is suitable for the top label, ask the database

  administrator to grant the privilege to the appropriate label.

  You have created the function with AUTHID CURRENT_USER, which means that the function is executed with the rights of the applicant (but not with the rights of the author). This means that the applicant must have grants (directly or through roles) on all used/accessible objects in the service. In your case the user USER2 has not granted with EXECUTE on the class/source Java test. Class HelloWorld, causing the ORA-01031 exception. You create service without AUTHID CURRENT_USER (i.e. with AUTHID DEFINE, which is by default, if you do not have a specific reason to use AUTHID CURRENT_USER) or grant EXECUTE on JAVA test SOURCE. Class HelloWorld to User2.
