• How to create an associative array

  Is it necessary to creat a table associated with?

  index by BINARY_INTEGER

  CREATE OR REPLACE TYPE WEBINST.string_state_table AS TABLE OF varchar2(100) ;

  Yes,

  You must use the index by clause to create an associative array. Other wise, it is called as a nested table.

• How to share an associative array throughout the entire instance?

  Hi all
  
  I have an associative array containing a lot of data and it would barely change, I want to keep in memory and share all throughout the entirety of an instance and make sure that all the sessions for all users, get the same table associative, is - it possible?
  
  Thanks in advance.

  I just want to keep it in memory and share them throughout the entire instance and make sure that all sessions of all users get the same associative array, is it possible?

  Why do you want to keep in mind?
  Will using a table for it, who has access frequently, almost will always be in the buffer cache, performance of the cause of the problems for you?

  The only other way to keep the data in memory in the world FLEURIDAS to all database sessions is to use the global application context functionality. With which you can store [name, value] pairs in memory and easily (read) access using integrated SYS_CONTEXT.

• Associative array in an array?

  I joined a project to a flash game, and being the only one that has any type of coding experience, I have, of course, make the ActionScript.

  However, the coding I did that day where, in PHP, not in ActionScript.

  so, even if we just started, I have a problem:

  I need to create a list of objects and enemies, that the game has.

  the elements? No problem:

  var items:Array = new array("Coin", "Tools",.....);
  

  so which works fine now, but the bad guys are not a problem, now, I have the same base table.

  Yet I need an associative array in another associative array.

  Since I have no idea how to do this in ActionScript, this is what I mean, but in the State would be in PHP:

  array("enemy_1" => array("drops" => "coins/10", "requires" => "credits/100"), "enemy_1" => array("drops" => "tool/
  Screwdriver")....)

  So I have an associative array of names of the enemy, and those who are associated with a new table showing information on the enemy.

  problem is that the above is PHP and I need that in ActionScript, I can figure out how to do an associative array, but not if you can pass an associative array as its value.

  Look into the Dictionary and Vector classes. Or just use the Object.

• An associative array, how the records using the loop counter?

  I'm trying to access a table on a click of a button element.  Complete creation, I have this: var = students ["Theo Arguna", "Leif Arneson", 'John Egan', "Sakura Nakahara", 'Rebecca Pilkington', "Debra Sutter"];

  the passage of the mouse button I put this:

  var myVariable = sym.getVariable("students.eq[0]");

  sym.getSymbol("message").$("Text4").html ("Click now to see" + sym.getVariable ("myVariable") + "working.");

  When I test I get "undefined" say where "$myvariable" is in the line above the code.

  Any suggestions on how to get the array element in this?

  Hello

  «"«You are almost there...»»»

  Put this in your creationComplete event:

  sets the variables table students

  sym.setVariable ("students", ["Theo Arguna", "Leif Arneson", "John Egan", "Sakura Nakahara", "Rebecca Pilkington", "Debra Sutter"]);

  And put it in your button mouseover event:

  get the array element you want

• How can you specify the default value for the undefined array elements

  According to aid LV, the tables have two default values, the normal default value and the default value for the undefined array elements.

  I assume that there must be a way to specify the default value for later, but I can't find it anywhere.  Any ideas?

  I know that you can drag the item out of the table container.  Change the default value on this scalar element.  Then drag the item in table tank.

  Hi, smile,

  If you want to see records, you must put the lines in your table. Here's a solution: in this solution, I only edit the search_obj procedure of your package like this:

   PROCEDURE search_obj (obj_type VARCHAR2)
     IS
        test_tab   test_ttyp;
        test_tab_r   c_c1%ROWTYPE;
     BEGIN
          --test_tab;
          --Here we put something in test_tab
          OPEN c_c1;
  
          LOOP
               Fetch c_c1 into test_tab_r;
               exit when c_c1%NOTFOUND;
               test_tab(test_tab.COUNT + 1) := test_tab_r;
           END LOOP;
          CLOSE c_c1;   
  
          FOR i IN 1 .. test_tab.COUNT LOOP
            dbms_output.put_line(test_tab(i).empno);
         END LOOP;
  
     END;
  

  Here is the result:

• Cannot run the autonomous block for input of associative array parameter

  Hello

  I have created an associative array in a package-PKG_CMT_DAP

  TYPE r_supply_type_id IS RECORD(

  TYPE t_supply_type_id IS TABLE OF r_supply_type_id INDEX BY BINARY_INTEGER;

  How to update successfully.

  Created a stand-alone as block below

  Could you please help me where I am doing wrong?

  Kind regards

  Claudy Kotekal

  Claudy,

  While calling the procedure, you must declare the variable of type table. Give the values for the elements in the begin block and then pass that variable in the procedure. Something like below:

  Declare

  in_array PKG_CMT_DAP. r_supply_type_id;

  Begin

  in_array (1) .supply_type_id: = 100;

  in_array (2) .supply_type_id: = 200;

  in_array (3) .supply_type_id: = 300;

  test_prc (in_array);

  end;

  NOTE: There might be a few problems with my code syntax, but logic would be same.

  Try this and let me know.

  Thank you

• need help in the associative arrays indexed by varchar

  Hi, I wanted to fill an associative array that is indexed by varchar, but I'm confused by incrementing the pointer so that the next lines gets inserted into the next available place.
  sample data:
  type ty_tb_tab_acc is record (account varchar2 (30));
  type ty_tb_indx_acct is table of index ty_tb_tab_acc by varchar2 (35);
  
  cursor sampls_cursor is
  Select an account in sam_tab where the clause goes in here
  
  say that my cursor returns 20 accounts. now, I want these 20 accounts will be inserted in the table associative ty_tb_indx_acct
  How should I buckle and incrment table?
  
  Please share your ideas

  This must be done using SQL. Not the tables or collections or associative arrays.

  SQL is the MOST powerful language, that you have in the Oracle RDBMS. It is faster than PL/SQL, when it comes to crunch data. It is more scalable.

  So why then pull data SQL in PL/SQL (expensive) memory? And then shoot some more SQL data in memory of PL/SQL (expensive)? And then use PL/SQL loop processing to compare the two sets of data?

  SQL can do that very quickly and very efficiently - as it was designed for this specific purpose.

  See the JOIN, INTERSECT , and LESS SQL operations to compare data sets.

  Does it fast enough and I think it is necessary for using the pipeline to multiple joins functions to update the tables of FACTS so to speak.

  A pipeline returns data that are not indexed. So by default, using data from a pipeline function involves a full production table scan. That's why native SQL tables are better than a pipeline - as these are accessible and used optimally (via the index partitions, bitmaps, clusters, etc.).

  Since PTFS uses memory structures as associative arrays do, what are the main benefits of using TFP compared to the associative arrays in addition to the fact that in MFP memory structures are presented in the SQL format?

  Not the same structure. An associative array is typically a list linked and "indexed" differently.

  A normal array is accessible by compensation. Let's say it's an array of bytes 4 IEEE floats. 1st entry is at position 0 in the structure of memory. The 2nd entry at position 4. Etc.

  Index number of the table is used to determine the offset of this table cell in the structure of memory.

  An associative array is "indexed" using strings or dates or numbers (not sequential). Thus a structure like a linked list must be used. Access to the range means a search in this linked to the match index list and then read the value of this cell in the table.

  The associative arrays do exist in the SQL engine. It is a unique data structure of PL/SQL engine.

  As to the benefits of a pipeline - this is when the data must be processed and plain vanilla SQL is not able to do this and PL/SQL is required.

  Simple example. A flat web service XML data structure. A table of pipeline can use UTL_HTTP to make the service web call, retrieve the XML code and that the output data as rows and columns - in effect turning a web service interface into something that looks like a SQL table and can be used as if it were a table SQL.

  Reading Tom on the use of pipelines comments:
  http://asktom.Oracle.com/pls/asktom/f?p=100:11:2814739467100916:P11_QUESTION_ID:19481671347143

  Also when can I use associative arrays functions insteard table in pipeline?

  Associative arrays are useful for the only PL/SQL data. For example, which deals with the pair name / value that are placed by a customer and that are used to determine which query or process data. For the majority of the PL/SQL code and the treatment, associative arrays are not necessary. And often wrongly used that developers do not seem to understand what an associative array is and how it differs from a normal table structure.
