• Collection as a parameter in the function - help needed

  I have a function that returns 3 different values according to a given in parameter.
  Now, I want to return these three values.
  Instead of using three out parameters, how can I use a collection for return values.
  
  Please tell me the best way that returning multiple values (more than 3)

• Appeal procedure in another procedure using the Out parameter slider - lesson

  Hello

  I am new to Oracle development so first I wonder if it is a good place with a simple way of the of on how to create stored procedures?  I'm looking for the most part at this stage for a quick read.

  Second, currently have hacked and slashed my way into getting one built.  It has 3 parameters and an output parameter sys_refcursor.  This procedure works.

  I want to have another created procedure that will call the above procedure and loop through each row in the setting out and write to a file.  Can someone point me to an example of this by any chance?

  Thanks for the help.

  Hello

  Thanks for the reply.

  Here's what I have, but I'm getting many errors.  When I seem to fix one that I get a new one. Kind of like what it show me all questions vs one question at a time.  I never know if I create another error of my attempts at fixing what, in my view, could be the problem.  In any case, something to get used to.

  When you do any type of programming, take baby steps.  Write less code as possible, test what you wrote ' worm and, if it contains errors, correct them and test again.

  The PL/SQL compiler tries to show all errors, but often it is impossible to say what is a separate mistake, and which is a consequence of a previous error.  For example, the DECLARE statements in your code are perfectly valid PL/SQL statements, but they are the mistakes in the sense that they are not what you think, and you may not use them.  PL/SQL does not know that (I don't really know that, either, but I'm willing to guess in this case).  The works of compiler on the explanation that you really wanted to say SAID, until what it becomes obvious, maybe several lines later, that something makes no sense, but at this time, there is no way he could say that the undesirable DECLARE was the cause.

  So here is where I am stuck currently.  What I want should first, run the stored procedure and I think I do as you suggest.  Which returns data in the output parameter, which is of type sys_refcursor.  I think I would need to loop through each element that cursor and output to the file using the dbms_output you reference and like I did below.  This should be it.  Sounds simple enough, but it's where some of the basics for me.

  For example, by creating the procedure some examples have the name of the procedure and then some "AS", "IS".  When use the beginning and the end and when not I need?

  There is no difference betwwen

  CREATE PROCEDURE... AS and

  CREATE PROCEDURE... Use IS the one you prefer.  You must always one or the other, however.

  PL/SQL is written in blocks.  The basic structure of a block is

  DECLARE - optional, sometimes involved

  ...

  BEGIN

  ...

  -Optional EXCEPTION; forget it for now

  ...

  END;

  Almost all of the PL/SQL code is part of a block.  In fact, you could argue that anything not in a block isn't really PL/SQL.  (For example, CREATE PROCEDURE is really an SQL, PL/SQL not, it indicates the SQL that some PL/SQL compiler is coming.)

  You should always BEGIN and END keywords in a PL/SQL block; None is never optional.

  I think I'm doing the for loop correctly but I get an error on the portion of loop-end.  It is a part of these simple things that become I think that.

  That's what I have:

  CREATE OR REPLACE PROCEDURE APPS.boact_report_3

  AS

  DECLARE v_cur SYS_REFCURSOR;

  DECLARE v_file_out UTL_FILE.file_type;

  BEGIN

  I said earlier, DECLARED may be implied.  It's one of those places if there is nothing after CREATE PROCEDURE... IS and before STARTING, it is supposed to be a statement.

  You can have as many statements (0, 1, 2 or more) that you want in this section of the statement.  The semicolon at the end of each of them is all the separation you need each other; you don't need any keyword as STATED.

  Open the v_cur for

  bo_report (p_sv_id, p_start_date, p_end_date, out v_cur);  -stored procedure that girls v_cur witch is a sys_refcursor parameter.  It works

  END;

  BEGIN

  Don't forget, how to call a procedure is

  bo_report (x, y, z);

  not

  bo_report (x, y, z OUT);

  The key words are only necessary (and only used) in the declaration of a procedure, not in his appeal.  When you create a procedure, you decide if each argument is going to be an argument IN, an OUT argument, or IN OUT argument, and you tell the compiler that you decide.  When you call a procedure, you have no choice; each argument is IN, OUT or IN OUT has already been decided, and suffice to say compiling what are the variables (or expressions) that you use to play these predetermined roles.

  Dbms_output.put_line ('Date: ');

  v_file_out: =.

  UTL_FILE.fopen (' / public/scripts/smorau02 ', 'w_act.csv', 'W');

  FOR x IN v_cur

  LOOP

  () UTL_FILE.put_line

  v_file_out,

  x.cl_num | ','

  || x.wa_id | ','

  || x.Description | ','

  || x.a_date | ','

  || x.a_by | ','

  || x.v_Name | ','

  || x.SITE_NAME | ','

  || x.stage | ','

  || x.in_queue);

  END LOOP;

  UTL_FILE.fclose (v_file_out);

  END;

  Thanks again for the help.

  You have not to send the code to bo_report, so I can't run the procedure.  I do not notice any obvious mistakes immediately superior.

• Doubt about the passage collection (Pl/SQL table) in a procedure.

  Hi all
  
  I have developed a package of sample with procedure 1. Here, I spent the output to a table in the collection data and I am passing the array of the collection as a parameter out.
  When I run the proc, it worked for 1 scenario, but did not work for the other. I posted two scenarios after the code.
  

  pkg spec:
  
  create or replace
  PACKAGE IMP_EXP_BKUP_PKG
  AS
    TYPE test10_tbl2 IS TABLE OF test10.t1%type INDEX BY BINARY_INTEGER;
    v2_test10 test10_tbl2;
    PROCEDURE manpower_list(v1 number, v2 out test10_tbl2);
  END IMP_EXP_BKUP_PKG;

  create or replace
  PACKAGE BODY IMP_EXP_BKUP_PKG

  PROCEDURE manpower_list(v1 number, v2 out test10_tbl2)  AS
  BEGIN
    SELECT t1 BULK COLLECT INTO v2 FROM test10 WHERE t4 = v1; 
  END;
  END IMP_EXP_BKUP_PKG;

  Scenario 1:

  DECLARE

• Questions about apex_web_service.make_request and collections

  Hello
  
  I began using with Apex Web services, and I have a few questions about the apex_web_service.make_request procedure. You can pass a name of the collection as a parameter. I'm a little confused on this parameter from the collection...
  
  This is perhaps a silly question, but the documentation is not very clear, so... This procedure always inserts just a line in the collection (with the XML returned by the web service call), or are there cases where several lines will be inserted?
  
  If there is still only a single row, what are the practical reasons to use a collection for her? I ask because in most cases interest you about the columns/rows to display in a form or a report in the Apex and I don't see the advantage to store in a collection of single-row, but I may be missing something...
  
  If the response contains several rows of data, it will be automatically extract the lines and insert them into the different lines of the collection? (posts...)
  
  What is the best approach then to extract several rows returned in the XML response and insert them into a collection? Currently I use XMLTABLE in a loop and call apex_collection.add_member for each row returned. is there a better way to do it?
  
  Thank you
  Luis

  Luis,

  the webservice returns only one row in the results collection.

  XMLTABLE using is a good idea, instead of using a loop, you can also use APEX_COLLECTION. CREATE_COLLECTION_FROM_QUERY or CREATE_COLLECTION_FROM_QUERY_B (B for bulk which may mean 'fast').

  brgds,
  Peter

• access a type of user to another schema (collection)

  /
  
  CREATE TYPE TT_my_table  OID '0815'

  I use the TT_my_table collection as a parameter of a procedure type.
  
  Intended to test, I would like to call this procedure from another schema (SQL-developers UT repository). This is why I need 'access' to the collection type of this test pattern.
  
  What are the rights I give to achieve?

• using the collection as an array

  I'm a collection to the parameter and want to join another collection that lines with another table. I want that, because if I'm going to do the operation loop taking elements one by one and in comparison with the record in the DB table, the performance should be degraded.

• Error-307650 during a sequence in real-time with API LV

  I created a basic real-time sequence that checks the time it takes a signal reach a certain threshold.

  

  On the side of the LV, I use the API to call this sequence. I make sure that all channels and settings are defined as in the examples. However I get 307650 error that says "NEITHER VeriStand: Index was out of range." Must be non-negative and less than the size of the collection.

  ' Parameter name: index.

  Any suggestion to help here? THX. Code is attached.

  There are two problems here:

  1. The Stimulus profile editor is not indicating that there is an error with this sequence, although there is a. Note that the variable InitialTime is used in an expression, but is not declared as a parameter or a local variable.

  2. you get an error at runtime because of it, but it's not terribly useful (index out of range).

  You can fix this by adding a local variable of InitialTime to your sequence. I dropped the CAR 338386 about this bug.

  Once you do this, there is something extra, you will need to set in your VI which runs the sequence so he could get the results of the sequence properly. You use correctly the value of the sequence name to read the back of the sequence Variable. You use the Session name used during the deployment of the sequence. Which does not match the name sequence.

  To get the name of the sequence, use VI to get all the names sequence on your session profile of stimulus to get the array of names for all of the top level of the session sequences, then index on the first point, given that you only use a single sequence. Example below:

  This default Adobe navigation can be great for some applications, but not mine. Indeed, it makes navigation more confusing since I was a dedicated exit the menu for my navigation app.

  Is there some way to disables the default / built by striking horizontal swipe, top menu and scrubber? Thank you, thank you.

  There isn't a way to disable it. There are a few hacks involving overlays full HTML screen, but that will not interfere with your sliding menu.

  In 2015, DPS, you can disable the horizontal navigation within a collection using a parameter on the collection, but you will always get the top to the top menu when the reader clicks on the page. There is no Purifier DPS in 2015.

  results of a table and use it.

• refcursor or object?

  Working on a stored procedure that is called by the java application.
  
  I do not know which of the following option is better and in which case:
  
  1 stored procedure return/accepting a SYS_REFCURSOR parameter
  or
  2. at the level of schema:
  
  TYPE AS OBJECT emp_attrb_obj (attribute_type_id NUMBER (10),)
  attribute_val VARCHAR2 (50)
  );
  create or replace
  TYPE emp_attrb_type AS THE emp_attrb_obj TABLE;
  
  and then have a stored procedure accepts or returns a parameter of type emp_attrb_type
  
  Thank you

  Well, a java application is unlikely to be able to pass a ref cursor, your procedure will therefore not need to accept a. Other than that, it really depends on how the data that you expect to get past back.

  I have a number of stored procs called by java applications that return a single row in a table. In these cases, I often return an object, since it saves a step for Java guys who can use it more or less directly. Is there is not a limit on the number of rows returned exlplicit, then I would always return a refcursor.

  If the java app must pass a set of values in the stored procedure (for example get this list of employees), then I would have java pass an array of objects (an array of records) to the stored procedure. It keeps me from having to parse a delimited string of values.

• Call a procedure only once for the last place of the trigger FOR EACH ROW

  Hello world
  
  I wonder if someone could help me in the execution of the trigger. My use case what follows:
  
  -a trigger after each INSERT or UPDATE operation;
  -use FOR EACH ROW algorithm for relaxation;
  -collect certain values inserted/updated fields as: new.uuid and store in a set defined on the layer of the package;
  -only for the last inserted/updated line call a procedure from the global collection with the values collected as a parameter;
  
  Is it possible to be implemented for the type of the LINE FOR EACH of the trigger? Fact one: new identifier or trigger itself have special attributes such as COUNTY, SIZE to set a size of data inserted or changed to conditional logic? Is there another solution to possible workaround for thoughtful use cases.
  
  Thank you

  Hi, Andrey,

  I suggest you use 2 triggers:
  (1) A FOR EACH ROW trigger, as you described, to collect relevant data and store it in a temporary table overall or variable poackage. Whenever the trigger is activated, it will overwrite all the data from the previous row.
  (2) AFTER ( NOT FOR EACH ROW) trigger that calls the procedure by using the saved data.
