• What is the difference between associative arrays and nested tables?

  Hello
  What is the difference between associative arrays and nested tables?
  
  nested tables cannot be indexed by other than pls_integer and unlike nested tables table associative cananot be declared at the schema level.
  
  is there any other difference set apart from the diff above 2?

  What is the difference between associative arrays and nested tables?

  Name-value pairs (associative) against a list of values (table standard/nested table).

  nested tables cannot be indexed by other than pls_integer

  They are not "indexed" the way in which an associative array is indexed. A standard table is referenced by the position of the cell in the table. This position is essentially the offset of the memory of the cell from the start address of the table.

  Can not solve a cell in an associative array directly via a memory offset index. You place a cell reference value it by his 'name' (a search in the linked list/hash table).

  The following example shows the difference between the pairs of name / value and a list of core values.

• Interpolation and Garbage Collection problem

  No matter what I I can not solve a problem with AS3 Garbage Collection of tween I'll have it is havoc on my tween instances works correctly/consistently. Some Sprites never tween at all, some do it but only part way. And it different effects almost every time.
  
  I recently read about AS3 Garbage Collection and badly referenced interpolations and other asynchronous forums is picked up in the Middle process fairly. I feel the inconsistent behavior of signature that the I have read.
  
  I tried to use the static properties level and not static class to store the references to my Tween instances so that they will not be shown for the GC. No luck. I placed references to these in the class-level tables, I also used static to() TweenMax method, which ensures that there will be the shield of GC and its static constructor instantiation not alt., with persistence: true. I have also set up another package custom; GCSafeTween(), others says it's as it should be, but it does not work in my case.
  
  To test the GC problem, I edited the two eventListerners() in the Adobes fl.transitions.Tween so that their default weakReference property was false. This is properly the work of Tween. But this is a terrible solution.
  
  Here is my code. Its a bit stripped down just to show the configuration.
  Thank you for helping me solve this one!
  
  
  

  The problem is finally solved.
  I had another Alpha tween StackDisplay targeting a Sprite that is nested inside the main Sprites that I tried to tween Alpha. I noticed that if I planned other properties of the target Sprites they work always as interpolated. It was only the Alpha which would get stuck from time to time.

  JPSoul thanks for helping me to tackle the problem in a different way and get finally resolved.

• What is the preferred means of data transmission as a type of record between the nested table of pl/sql program or an associative array

  What is the preferred means of data transmission in the associative array of the nested table record vs

  Choose between Nested Tables and associative arrays

  The two nested tables and associative arrays (formerly index - by tables) use similar index notation, but they have different characteristics when it comes to persistence and ease of passing parameters.

  Nested tables can be stored in a column of data, but can of associative arrays. Nested tables can simplify the SQL operations where you would normally join a single-column table with a larger table.

  Associative arrays are appropriate for relatively small lookup tables where the collection can be constructed in memory whenever a procedure is called or a package is initialized. They are good for the collection of the information volume is unknown beforehand, because there is no fixed limit on their size. Their index values are more flexible, as associative array indices can be negative, can be no sequential and can use values of string instead of numbers.

  PL/SQL automatically converts between the bays of the host and the associative arrays that use values of digital keys. The most effective way to move the collections to and from the database server is to implement data values in associative arrays, and then use these associative arrays with erections in bulk (the FORALL statement or BULK COLLECT clause).

• Associative arrays

  Quoting docs.oracle.com lines
  
  
  Associative arrays are used to represent sets of data of arbitrary size, with quick search of an individual element without its position in the table and without
  having to loop through all the elements in the array. Here is a small example
  
  DECLARE
  TYPE population_type IS TABLE OF NUMBER INDEX OF VARCHAR2 (64);
  country_population population_type;
  continent_population population_type;
  howmany NUMBER;
  that VARCHAR2 (64);
  BEGIN
  country_population ('Greenland'): = 100000; -Creates the entry
  country_population ('Iceland'): = 750000; -Creates the entry
  -Research associated with a value chain
  howmany: = country_population ('Greenland');
  continent_population ('Australia'): = 30000000;
  continent_population ('Antarctica'): = 1000; -Creates the entry
  continent_population ('Antarctica'): = 1001; -Replaces the previous value
  -Returns "Antarctic" which comes first in alphabetical order.
  who: = continent_population. FIRST;
  -Returns "Australia", which comes last in the alphabetical order.
  who: = continent_population. LAST;
  -Returns the value corresponding to the last key, in this
  -case of the Australia population.
  howmany: = continent_population (continent_population. LAST);
  END;
  /
  
  
  
  my doubt is in what regards the statement "with a quick search of an individual element without its position in the table".can someone give a small relevant example. Therefore the associative arrays is also appropriate for relatively small lookup tables where the collection can be constructed in memory eachtime, a procedure is called? Thanks in advance...

  Think of it as gradually close equivalent to a hash of key/value pairs. When you want to insert an item provide you the key, Oracle axe key to find the entry in the hash table. It doesn't matter if the entry is the first, last, or any other arbitrary position in the table.

  The scope of the variables of the procedure is only the duration of the procedure. They are built when the procedure is called and destroyed when the procedure ends.

  If any associative array created in the procedure must be small to minimize the impact on the performance of the table fill. If the procedure performs complex calculations or ETL one record at a time, it is more efficient to get a value from the array instead of having to re - query a database table for him.

  For example, for the United States, a list of 50 State and their full name abbreviations that can be stored in an associative array and procedure could extract the code of the State of a data element, and quickly find the name of the State of the table. It would be faster than executing a query on the database on a lookup table.

• Table of multiplication using associative arrays

  DB version: 10.2.0.1.0
  
  Here is a code for the multiplication of 14 up to 100 table. How can I store these values in an associative array and each element of the Bulletin Board so that it produces the same output as the code below.

  Declare
  --TYPE v_number_type IS TABLE OF number INDEX BY PLS_INTEGER;
  
  v_number     number:= 14;
  v_multiplied_by     number:= 1;
  v_result     number;
  begin
  
       for i in 1..100
       loop
            v_result:=     v_number * v_multiplied_by;
            dbms_output.put_line(v_number||' multiplied by '||v_multiplied_by||' = '||v_result);
            v_multiplied_by:=v_multiplied_by + 1;
       end loop;
   
   end;
   /

  Result would be

   14 multiplied by 1 = 14
   14 multiplied by 2 = 28
   14 multiplied by 3 = 42
   14 multiplied by 4 = 56
   14 multiplied by 5 = 70

  It's a bad habit to "select into... of double" where you could just assign a value.
  It's your code, that boiled down to this:

  DECLARE
     TYPE v_number_type IS TABLE OF VARCHAR2(40)
        INDEX BY PLS_INTEGER;
  
     v_number     PLS_INTEGER   := 14;
     v_res_type   v_number_type;
  BEGIN
     FOR i IN 1 .. 100 LOOP
        v_res_type(i) := TO_CHAR(v_number) || ' multiplied by ' || TO_CHAR(i) || ' = ' || TO_CHAR(v_number * i);
     END LOOP;
  
     FOR j IN v_res_type.FIRST .. v_res_type.LAST LOOP
        DBMS_OUTPUT.put_line(v_res_type(j));
     END LOOP;
  END;

• How to prepare list for garbage collection after drag and drop operation

  Hi all

  I have a view in a mobile application that contains a list with the help of drag / move. The problem I encounter is that the NativeDragManagerImpl maintains a reference to this list in its _dragInitiator and _relatedObject properties. It is not a memory leak by - say, because the reference will be replaced the next time make drag and drop is used, however, my view that preclude any garbage collection, causing an unacceptable peak memory.

  Here is an example which illustrates the problem (app default AIR using Flex 4.5.1):

  Main.MXML

            </s:List>
  </s:Group>
  
  

  If you drag items to the list on the right, there is always at least one instance of ListGroup stuck in memory for the duration of execution (as seen in the profiler).

  Is there a way to perform cleanup on the DragManager (or in fact the underlying DragManagerImpl) upward to a time of my choosing? Thoughts or ideas will be greatly appreciated!

  Thanks a lot for your time!

  I think I'd be monkey-patch NativeDragManagerImpl.  And create a bug report.

  You call unload() on objects that you cancelled - where the error.

  You should do something like:

  {if (loader2)}

  loader2. Unload();

  }

  As for the null value passed into the function - null is a default value. In this way, you can call the low past nothing:

  Down()

  Or you can use it as a handler in which case it will be called by the Auditor:

  Down (mouseEventInstnace);

• Garbage Collection, external swf and XML

  I did tons of research on the AS3 garbage collection. I have a decent knowledge of it, but I CAN'T find any info about the deletion of xml data. The worst thing is, I have no control over the version of the file (AS2 or AS3) swf file I'm loading. Unfortunately, I'm loading AS2 swf (with an outside provider that will not show you any code) in a film of AS3. When I run garbage collection, the data from the xml file / is not deleted and I can't understand how get rid of it. The problem is, once a file is loaded which calls an xml file, no other files cannot load an xml.
  
  If anyone knows how to clear the XML, please fill me in.
  
  Thank you!

• Difference between the nested table and an associative array

  Hello
  While going through the link http://download.oracle.com/docs/cd/B10501_01/appdev.920/a96624/05_colls.htm
  I came across the statement that
  Nested tables can be stored in a column of data, but of associative arrays
  
  So I tried the following statement for the associative arrays where he works

  create type t_nm is table of number index by binary_integer

  The t_nm of type above name is stored in USER_TYPES.
  
  
  So how can we say that associative arrays can not be stored in DB.
  
  Please correct me if I'm wrong.
  
  Thank you

  Concerning

  REDA

• Settlement and associative array (?)

  I adapt a class as explained in 'Flash Application Design Solution'. The code is used to power a system of menus.
  
  In the original code, the dashboard menu system is hardcoded in this way:
  var MenuData:Array = [{title: 'Advanced Flash Interface Design'}, {title: 'Flash 3D Cheats Most Wanted'}, {title: 'Flash 8 Essentials'}, {title: "Flash Cartoon Animation"}];
  
  This is an associative array?
  
  In my code, I would rather use an XML file to populate MenuData, but something is missing in my understanding. The code below does not work since there is no title 'label' associated with my table data.
  
  

  I found the solution:
  MenuData.push ({title: photos . attributes.nom});
  

• Associative array

  I have a table proj_test .i want to recover the data in the associative array.

  How to do?

  create table proj_test as  
    select 1 as id, 1 as rn, 'Fred' as nm from dual union all  
    select 1,2,'Bloggs' from dual union all  
    select 2,1,'Scott' from dual union all  
    select 2,2,'Smith' from dual union all  
    select 3,1,'Jim' from dual union all  
    select 3,2,'Jones' from dual  
  
  

  You need not Associative array if you do a bulk of collect. You can use the nested PL/SQL table type.

  11g and more

  declare

  is of type tbl table of the proj_test % rowtype;

  tbl l_tbl;

  Start

  SELECT id, rn, nm bulk collect into l_tbl

  of proj_test;

  because me in 1.l_tbl.count

  loop

  dbms_output.put_line

  (

  RPAD (to_char (l_tbl (i) USER.USER), 10, ' ')

  || RPAD (to_char (l_tbl (i). (RN), 10, ' ')

  || l_tbl (i) .nm

  );

  end loop;

  end;

  Before 11 g

  declare

  type id_tbl is table of the proj_test.id%type;

  type rn_tbl is table of the proj_test.rn%type;

  type nm_tbl is table of the proj_test.nm%type;

  id_tbl l_id;

  l_rn rn_tbl;

  l_nm nm_tbl;

  Start

  SELECT id, rn, nm bulk collect into l_id, l_rn, l_nm

  of proj_test;

  because me in 1.l_id.count

  loop

  dbms_output.put_line

  (

  RPAD (to_char (l_id (i)), 10, ' ')

  || RPAD (to_char (l_rn (i)), 10, ' ')

  || l_nm (i)

  );

  end loop;

  end;

• Associative array as a type of database

  As it is very well create an associative array inside a stored procedure:

    type urltype  is table of varchar2(32767) index by varchar2(30);
  
  

  Can it be created as a type of database at the level of the schema?

  Non - associative arrays are a function of PL/SQL.

  See table 5-1 in the doc of the PL/SQL language for a description of each type of collection and where (pl/sql, sql, etc.) they can be used.

• Associative arrays... items in the index

  I can control the index of an associative array like that...
  

   TYPE aat_id IS TABLE OF PLS_INTEGER INDEX BY PLS_INTEGER;
    aa_ids aat_id;
  
  BEGIN
  
       aa_ids(1) := 3;
       aa_ids(2) := 8;
       aa_ids(2) := 10;
       
  aa_ids.delete(2);
  
  dbms_output.put_line(aa_ids.count);
  
  END;

  How can I control the index in the statement of collection in bulk as follows... so that I can delete records using this index
  

   SELECT decode(mod(rownum,2),1,1,2), object_name BULK COLLECT INTO aa_recs
       FROM   all_objects WHERE  ROWNUM <= 6;

  Thank you

  Using not PL/SQL and bays of PL/SQL at all - just using simple native SQL.

  Before bulk collection and construction of an associative array, for the use of the values in table for future SQL operations, I rather to store the collection of values in a TWG (global temporary table) instead. A TWG can be indexed - and can thus provide much better access to the data as an associative array. He played better. It can be used via SQL, native mode.

  The best place for the data is in the database. Not in the PL/SQL layer. This means that in SQL tables and not in PL/SQL tables or collections.

  There are very few situations in PL/SQL, which require the use of associative arrays. If few, the majority of the PL/SQL code using associative arrays, IMO do badly. And what you've posted so far, I do not see a specific requirement for associative arrays.

  So be sure you use the correct feature - and make sure that it is also well put to use in your code.
