The execution of a function in the procedure, passed as parameter string

Hello

He must create a function, pass the name of the function to a procedure, and then run this function in the procedure.

For example:

Hello from the FUNCTION to CREATE or REPLACE

RETURN NUMBER

IS

BEGIN

RETURN 23;

END;

/

CREATE OR REPLACE PROCEDURE pro_fun (v_fun VARCHAR2, v_cal OUT NUMBER)

IS

BEGIN

v_cal: = exec v_fun; <-error on this line

END;

/

Now my plsql block annonymous where I'm passing function as sting of procedure:

DECLARE

VARCHAR2 (30) v1.

NUMBER of v2;

BEGIN

v1: = "Hello";

pro_fun (v1, v2);

DBMS_OUTPUT. Put_line ('VALUE IS' | v2);

END;

/

pro_fun (v1, v2);

*

ERROR on line 6:

ORA-06550: line 6, column 1:

PLS-00905: object SCOTT.PRO_FUN is not valid

ORA-06550: line 6, column 1:

PL/SQL: Statement ignored

How below line of procedure must be written to perform this function.

v_cal: = exec v_fun;

Try something like this:

create or replace function forum_hello return number

is

Start

Back to 123;

end forum_hello;

/

create or replace procedure forum_call_function (function_name_in in varchar2)

is

number of l_returnvalue;

Start

run immediately "begin: l: = ' |" function_name_in |'; end;' using l_returnvalue;

dbms_output.put_line (l_returnvalue);

end;

/

exec forum_call_function ('forum_hello')

Sincere greetings,

  • SQL that passes to the procedure as a parameter query

    I'm trying to accomplish what seems so simple and yet I can't do things. I want to pass a sql query via a parameter to a procedure. In this procedure, I want to loop through the results and create options for a selection list. I tried to use EXECUTE IMMEDIATELY, sliders, SYS_REFCURSOR, etc, but nothing seems to be quite right. Any ideas on how to achieve this? Thank you!

    A variation would be to use DBMS_SQL to ANALYZE and DESCRIBE the results.

    In this way, you can check to make sure that you have found a SELECT statement that returns only 2 columns.

  • Opt for the PROCEDURE or FUNCTION


    Hi all

    I wonder if someone tell me that when will I go to the PROCEDURE orFUNCTION?.. I did research and I think if we have to perform some sequence of statements then we use procedure and if we need to perform some calculation then we create function. In addition, When we need to assign function return value into variable. Appreciate you valuable suggestion... Many Thanks

    Hello

    An important distinction is that only functions can be called from SQL statements.

    SOM restrictions apply.  If a function is called by a SQL statement, this function does not perform any DML (for example, INSERT), or call any other function or procedure that does it.  If a function is called by a SQL statement, you should not have any OUT or IN OUT arguments.

    How do you intend to use the procedure or function?  Give specific examples of things you can do in PL/SQL, and then people can give you accurate answers.

    CREATE OR REPLACE PROCEDURE FORMAT_STRING ( string_in IN OUT VARCHAR2) AS

    variable session_var varchar2(200)
call join_strings ('I Love','you') into :session_var;

    If you want to do it in PL/SQL, you can use an anonymous PL/SQL block like that.

    set serveroutput on
declare
  session_var varchar2(200);
begin
  session_var := join_strings ('I Love','you');
  format_string(session_var);

exec :session_var := join_strings ('I Love','you')

exec format_string(:session_var)

    Strange question to ask.

    Yes. This is the standard behavior in most (if not all) procedural and object oriented languages.

    A procedure, function or a method is a unit of code.

    You can call one of the other units. Units can call themselves (recursion). Technically, this means simply by pushing the battery current (to save the stack of the current device memory), the call to the new unit and then popping up battery when control is returned to the unity of the appellant.

    There are very few exceptions to this. The only one that comes to mind programming languages I've used through the years, is natural 1 - could not call a new unit of code to replace the existing one in memory. If no call-and-return was possible.

    Exactly what did you ask this question? Some newcomers to confused Oracle SQL and PL/SQL - two different languages aside server. And then also mistaken for PL/SQL client command vocabulary of SQL * more.

    You will need to make sure that understand the basics of programming (applies to most current programming languages) and Oracle concepts.

  • 403 Forbidden error of execution of the procedures of the URL of the browser stored

    I am currently trying to run a simple stored procedure (ea.hello_world, where "ea" is the pattern and "hello_world" is the name of the procedure) a URL from the browser, but am getting a 403 Forbidden - error message "you don't have permission to access /pls/apex/ea.hello_world on this server. I use APEX 3.2 with Oracle 11 g and mod_plsql and gave the steps of apex_public_user. Any thoughts on what I am doing wrong?

    Here is the process I have used so far:

    Create the "Hello_World" procedure in the "EA: schema

    create or replace
    procedure hello_world
    is
    Start
    HTP. Print ("'Hello World!");
    end;

    I then successfully granted to run the apex_public_user procedure:

    Grant execute on ea.hello_world to apex_public_user;

    Then, I tried to call the stored procedure from the browser using the following syntax:

    http:// < Server >: < port > / pls/apex/< schema >. < Procedure & gt;

    I also experimented with the use of a public synonym and the configuration of the wwv_flow_epg_include_mod_local, but I do not think that the function s relevant since I'm using mod_plsql and not the embedded pl/sql gateway.

    Hello

    If you have below the line in dads.conf, then wwv_flow_epg_include_mod_local sets

    PlsqlRequestValidationFunction wwv_flow_epg_include_modules.authorize

    Try:
    Create public synonym

    CREATE PUBLIC SYNONYM hello_world FOR ea.hello_world;

    Grant privilege to execute procedure to the public

    GRANT execute on hello_world to public;

    Then change the APEX_030200.wwv_flow_epg_include_mod_local function

    CREATE OR REPLACE FUNCTION
APEX_030200.wwv_flow_epg_include_mod_local(
    PROCEDURE_NAME IN VARCHAR2)
RETURN BOOLEAN
IS
BEGIN  

    IF UPPER(procedure_name) IN (
          UPPER('hello_world'))
   THEN
        RETURN TRUE;
    ELSE
        RETURN FALSE;
    END IF;
END;
/

    Then try
    http://:/pls/apex/hello_world

    If you can now run your procedure in URL, you can then low and e.g. grant execute procedure to the user of DAD.

    You can try to create a table to record the execution time of each procedure...
    For example:

    -table of log´s
    create table executation_log (obj_name varchar2 (120),)
    VARCHAR2 (120) of the event.
    time_execute timestamp);

    -log´s procedure
    create or replace procedure prc_log (p_obj_name in varchar2,
    p_event in varchar2)
    is

    pragma autonomous_transaction;

    Start

    insert into executation_log (obj_name, event, time_execute)
    values(p_obj_name,p_event,SYSTIMESTAMP);

    end prc_log

    declare

    Start

    -call the log´s procedure
    prc_log (p_obj_name-online 'frist_object',
    p_event-online 'start');

    -call your drifter
    frist_object;

    -After the procedure of log´s you call compare the process start and end
    prc_log (p_obj_name-online 'frist_object',
    p_event-online "finish");

    -new
    prc_log (p_obj_name-online 'second_object',
    p_event-online 'start');

    second_object;

    -call once again, once again, once again
    prc_log (p_obj_name-online 'second_object',
    p_event-online "finish");

    end;

    -Drifter, then select table log´s
