• Difference of procedure & function

  Hi all

  After citing some tutorials, I got to know that the difference between the procedure and the function is that the procedure may or may not return a value as the function must return a value to the calling program. Given below is my procedure. & He would compare the lower of the two numbers would be smaller than

  create or replace procedure findmin

  (

  x in number,

  there in numbers,

  z series

  )

  is

  Start

  if(x<y) then

  z: = x;

  on the other

  z: = y;

  end if;

  end;

  declare

  c number;

  Start

  findmin (23,45,c);

  dbms_output.put_line (c);

  end;

  Here's my function even if it does the same thing.

  create or replace function findmin_fun

  (

  x in number,

  y number

  )

  Return number

  is

  number of z;

  Start

  if(x<y) then

  z: = x;

  on the other

  z: = y;

  end if;

  Return z;

  end;

  declare

  Start

  dbms_output.put_line (findmin_fun (56,28));

  end;

  I would like to know under what are all the scenarios of the procedure and function would be used. And also I want to know could do dml as insert, update, and delete operations

  If so, could you guys explain me with some examples to expose DML operations on functions

  After citing some tutorials, I got to know the difference between the procedure & function is that the procedure may or may not return a value as the function must return a value to the calling program.

  Not quite.

  A procedure does NOT return a value - it can fill in the parameters OUT or INOUT but which is NOT considered to be "of return values.

  A function ALWAYS returns a value that can be null. The only exception is if the function throws an exception.

  My procedure is given below. It would be to compare the lower of the two numbers & would mean that smaller

  Not quite - the procedure returns NO value. You use it to try to fill one OUT parameter, but it's NOT the same.

  I would like to know under what are all the scenarios the procedure & function would be used.

  Functions can be used in SQL; procedures cannot be used in SQL.

  The functions return a value; procedures of does NOT return a value.

  Use the functions when you need to return a value; Use the procedures when you do NOT need to return a value.

  It is not possible to list 'all scenarios' for one or the other, because there may be ANY NUMBER of possible scenarios.

  And also I want to know could do dml as insert operations, update & delete

  What happened when you tried?

  The best and fastest, to learn is to actually TRY THINGS. Don't be afraid to break the Oracle by actually writing code and tests of things yourself.

  If so, could you guys explain me with some examples to expose DML operations on functions

  The Oracle documentation have a LOT of examples of using functions and procedures and include the code of the example.

  https://docs.Oracle.com/CD/E11882_01/AppDev.112/e25519/subprograms.htm#CHDBEJGF

  The internet has even more examples of code.

• Updated APEX collection error ORA-04044: procedure, function, package, type

  Hi all
  
  I am trying to update the APEX MEMBER of the COLLECTION and encounter errors:
  
  
  1 error has occurred

  The process will take place after SUBMIT and validation.
  
  The code I used to add a colletion APEX will work perfectly and is as below
  
  -Initialization Collection PHASE_COLLECTION
  BEGIN
  IF THIS ISN'T APEX_COLLECTION. COLLECTION_EXISTS('PHASE_COLLECTION') THEN
  APEX_COLLECTION. CREATE_COLLECTION ('PHASE_COLLECTION');

  What I tried to use APEX_COLLETION to check the overlap between the date_range.
  The requirement is just to display a warning if the user adds a record to the new phase or update record of current phase may overlap between the order of phase together.
  Table PHASE_MEMBERSHIP script is
  
  CREATE TABLE 'PHASE_MEMBERSHIP '.
  (
  ACTIVATE THE "MPM_ID" NUMBER NOT NULL,
  ACTIVATE THE "MPM_ENG_ID" NUMBER NOT NULL,
  ACTIVATE THE "PHASE_NUMBER" NUMBER (2.0) NOT NULL,
  "DATE_STARTED" DATE NOT NULL ACTIVATE.
  DATE OF THE "DATE_FINISHED."
  'NOTES' VARCHAR2 (2000 BYTE),
  'DATE_CREATED' DATE NOT NULL ACTIVATE.
  ACTIVATE THE 'CREATED_BY' VARCHAR2 (20 BYTE) NOT NULL,
  NUMBER (2.0) 'ACTIVE' DEFAULT 1 ACTIVATE NOT NULL)
  
  So, basically, I want to fill the documents associated with a particular to a collection of APEX called PHASE_COLLECTION MPM_ENG_ID.
  Then when the user specify date_started and date_finished, it will update/insert the APEX collection first.
  Then the rank based on audit collection date
  http://www.Oracle-base.com/articles/Misc/overlapping-date-ranges.php
  then display the warning to ask the user to confirm message.
  
  But then I'm stuck at the step of updating COLLECTION of APEX.
  
  If anyone has any ideas on what is wrong, please help.
  
  Thanks in advance.

  Your syntx error line number should give you the trick - it is not a member of the update, rather the SQL - you are referring to apex_collection, not apex_collections view dictionary.

• Database Validation function Question

  In the Page 37 of the APEX_listener_v1.pdf, it is mentioned that we can create a function "check_valid_procedure".
  
  I guess it's similar to the version of the EPG, wwv_flow_epg_include_mod_local.
  
  My problem is that the admin screen will not accept it.
  
  Request could not be processed due to the error:
  Sea 14 Jul 09:58:48 EDT 2010
  Database Validation function CHECK_VALID_PROCEDURE is not valid.
  
  
  Should what I use to create this function?

  You will need to prepend the proc with the diagram unless you've granted to public and have a public syn your help.

• Build a complicated procedure/function

  Hello world
  
  I am creating a complicated procedure.
  
  I have three columns:
  

  line     A          B        C
  1       5.5       3.2       -
  2       1.05     6.1       -
  3        0.6      7.8       -
  4        6.4     4.13      -
  5         -         -        8.98

  Column C contains a result. So, I need to find how this result was built. In other words, this procedure/function must answer the question:
  What are the numbers in columns A and B, which has contributed to achieve this result.
  In this example, we found that:
  

  C = B(1) + A(2) + A(3) + B(4) = 3.2 + 1.05 + 0.6 + 4.13 = 8.98

  (there is a condition: we cannot do so one number per line is selected.: A(1) + B(1).)

• solution in OWB, procedure/function

  I have different columns in different tables, with values 0 or 1.
  In the tables in the target, a 0 is no. and 1 Yes.
  
  What is the best way to implement this.
  a function/procedure on the database using as a transformation in OWB or
  is there a better solution in OWB.
  
  Another question: will I maps the columns separately or is there a way to map all columns through the 1 design element (transformation? expression?)?

  You will have problems with route mapping plug-in for the re-use of expressions since each use is considered to be a set of independent lines. That would leave functions as the first choice. ODI, reusable expressions can be made using the user-defined functions, with the latter in the code is placed online.

• Why is conversion of procedures &amp; functions due to lack of MySQL to Oracle?

  Hi all
  
  I'm trying to migrate a database from MySQL to Oracle using the Migration Workbench data in SQL Developer 1.5.4.
  I ran both the quick Migration Wizard and the Manual Migration process as described in the documentation.
  
  I get through the process very well, even if not everything is successfully migrated. Namely, stored procedures and functions of the database of third parties are not correctly migrated.
  The following text is listed in the Migration log for each of the stored procedures and functions:
  
  * "Limitation of the translation"procedure_audit requires a translation of the manual"met on the column of the stored procedure fse.procedure_audit line 0-0."
  
  If I look at the 'converted' model the procedure has been created and is set to NULL. The procedure of 'captured the model' original is commented out in the body of the procedure in the "convert" template Does anyone have any ideas as to why it's a failure? And how do I fix it?
  
  
  In addition, there seems to be a problem with the conversion of the index, particularly those that are 'MAJOR' indexes in MySQL not appear in models 'captured' or 'converted '.
  
  
  In addition, the migration log provides the following:
  
  * "Index 'customer_customer_id' on the 'customer' table ' has been ignored, because it is a duplicate of a constraint" * "
  
  Looking at the index in the original third party database, it does appear that an index on that column on the respective table. The ides why this happens?
  
  
  Here, any help would be immensely appreciated.
  
  Thank you

• DB procedure / function can return multiple values in a PL/SQL block

  Hi all

  
  

  I have a problem returning to the exit procedure following in PL/SQL because I have SELECT INTO variable but with no output back in my PL/SQL block even if I turned it into a function.

  
  

  . pls suggest.

  CREATE OR REPLACE PROCEDURE nominations (p_start_date AS, p_end_date IN DATE)

  IS

  v_day_id PLS_INTEGER;

  v_day_name VARCHAR2 (33);

  v_day_date DATE;

  BEGIN

  SELECT (2 + (p_start_date + (LEVEL - 1) + LEVEL - 1 - TRUNK (LEVEL - 1 + 1, "IW" + p_start_date)) AS day_id

  , TO_CHAR (LEVEL - 1, 'Day' + p_start_date) AS day_name

  , TO_CHAR (LEVEL - 1, "DD-MM-RRRR" + p_start_date) AS day_date

  IN v_day_id, v_day_name, v_day_date

  OF THE DOUBLE

  CONNECTION OF LEVEL < = 1 + p_end_date - p_start_date;

  END;

  /

  Your insert would be something like this:

  INSERT INTO PR_OPS_APPOINT_SETS (SPEC_CODE1, SPEC_CODE2, CLINIC_NO, SECTOR_ID, USER_ID, APPOINT_DATE)

  SELECT r.SPEC_CODE1, r.SPEC_CODE2, r.CLINIC_NO, r.SECTOR_ID, USER, d.APPOINT_DATE

  PR_OPS_CLINIC_RECS r

  CROSS JOIN)

  SELECT TO_DATE (TO_CHAR (LEVEL - 1, "MM/DD/RRRR" + p_start_date), "MM/DD/RRRR") AS APPOINT_DATE

  OF THE DOUBLE

  CONNECT BY LEVEL<= p_end_date="" -="" p_start_date="" +="">

  ) d

  WHERE SPEC_CODE1 = p_SPEC_CODE1

  AND SPEC_CODE2 = p_SPEC_CODE2

  AND CLINIC_NO = p_CLINIC_NO

  AND SECTOR_ID = P_SECTOR_ID;

  In terms of getting the parameters p_SPEC_CODE1, p_SPEC_CODE2, p_CLINIC_NO, P_SECTOR_ID...? I don't have enough information on your part.

• Plan does not show the local procedures/functions

  In the window structure the local procedure does not at all. Declared variables and cursors in the local procedure are displayed, but as if they where in the main proceedings.

  Local procedures and functions should be displayed in the window structure. It would be nice if the declares the variables and cursors of a local proceeding would be arranged in suchs a means, it is visible that they belong to this local procedure, perhaps using an indentation.

• 12.1.3 extension XSLT editor Query-database mapping function

  Hello

  , We are trying to move from 11.1.1.7 to 12.1.3 JDeveloper. We have developed a number of xsl maps in 11.1.1.7 using the function oraext:query - database Oracle extension (where the namespace oraext is xmlns:oraext ="http://www.oracle.com/XSL/Transform/java/oracle.tip.pc.services.functions.ExtFunc" "). This works in JDeveloper 11.1.1.7 when the test of the card where the call to the map looks like this:

  < xsl: value-of select = "oraext:query - database (concat (& quot; Select fvalue GetMapCodeList ("param1", "param2", "param3") of double, quot;), false (), false (), & quot;jdbc:oracle:thin:dbuser/dbpassword@dbhost:1521:dbservicename & quot;) "/ >"

  In the statement select above is "select GetMapCodeList" which is a function defined in the database which takes 3 parameters. This works very well for us in 11.1.1.7. We are new to 12.1.3 and we get an error test map XSLT in JDeveloper. The error is

  file:/[file path] / [file name] .xsl: XML-22044: function (error) Extension error: Error invoking 'queryDatabase':'java.lang.NoClassDefFoundError: oracle/jdbc/OracleConnection '.

  It seems that it cannot find the ojdbc6.jar file, but I don't see where that should be added.

  Edit:

  OK, I realized that the extension functions XPath of Oracle do not appear in my XSLT Map Editor component palette. I also see that when I change the XPath of the oraext:query - database is highlighted by JDev as being invalid. I think my problem is with the extension being not loaded XPath functions.

  Thanks in advance.

  Steve

  OK, after working with the support of the Oracle, the answer is that the ojdbc6.jar did indeed need to be added to the configuration of JDeveloper 12.1.3. To do this the following line was added at the end of the jdev.conf file:

  AddVMOption - Xbootclasspath/r:... /... /.. /oracle_common/modules/Oracle.jdbc_12.1.0/ojdbc6.jar

  The jdev.conf file is located in your Oracle_Home\jdeveloper\jdev\bin directory. Don't forget to adjust the relative path to match your environment. In addition, please note that the only spaces in the AddVMOption line are a space immediately after "AddVMOption".

  Another concern in this thread that the functions of data base in the XPath Group advanced components from the component Palette was missing. The groups Advanced general XPath XPath and XSLT components model will appear only in the component Palette if the application is a SOA application.

  A score more. I don't know if Oracle sees this as a bug and the ojdbc6.jar to be in the classpath without the user set it up like that in the jdev.conf. If it's a bug, and then if all goes well it will be resolved in a future release, and this configuration will be necessary.

• Get the CGI env variables in a database procedure using the new listener to the APEX

  I already posted this question in the earpiece of the Apex forum and still no response after a week. The original post is here:
  Download environmental CGI of APEX listener within the procedure of database
  
  So please forgive me for posting in this forum as well, but there is much more activity here.
  
  I would like to know how I can get the CGI environment to the listener of the APEX. For example, if I want to write a procedure that inserts into a table, the client web request originating IP address, how do it?
  
  I am familiar with the Oracle Http Server and mod_plsql, and I know how to call OWA_UTIL. GET_CGI_ENV to get this kind of information. How can I do this by using the earpiece of the APEX?
  
  In particular, how to do that when you call a custom (not in a workspace Apex) procedure? When I try now, I get an error owa_util. The cgi env seems to be empty or not initiated (owa.num_cgi_vars is null or zero).
  
  Specific settings:
  I have a web server running the last JDK, Glassfish and 1.1.4 Apex listener. It connects to another server running the last database 11.2. Apex is installed and running, but I'm not really developing a traditional Apex application in a workspace. I use it mainly as you would use mod_plsql. In other words, I have packages of pl/sql custom which are called directly via a URL. Applications must be sent by the listener to the database and DB executes the procedure and returns output using htp.p to send the text to the browser. And it works very well for this purpose. But if I want to call GET_CGI_ENV to get information such as IP address, the browser making the request, etc. I can't get with the OWA packages.
  
  Anyone can shed some light on this? If the listener of the Apex is not designed to do this, is it some kind of workaround that I can use to transfer such information to the database for each request?

  Hi Adam,.

  APEX is located on the top of the Toolbox for OWA. There is no appeal of the special procedure to be implemented.

  Kind regards
  Christian

• Calling a database procedure which returns the array as output parameters

  But what you can do...

  Try to create a new stored procedure, which returns the type of the database object.
  In this procedure, you can call the original procedure.
  Take what it returns and make the type object. That's what you need to retrieve your procedure ;-) (.. .huh?)

  function cf_2formula return number
  is
   val1 number;
   val2 number;
  begin
  
   val2 := :cf_1 * 100; -- or val2 := val1 * 100 --parameters not allowed in formula column function
  
   -- All the other code that you need inclusive of calling function, procedure as in any PL/SQL block can be placed 
  
   return (val2);
  
  end;
  

  Any calculation can be used in the service of the formula column
