Re: creating dynamic associative arrays

Hi, I need some advice on the following problem. I develop code that allows me to copy & paste a spreadsheet into a TextArea and parse text pasted to dynamically generate a DataGrid control. I assume that the first line of text contains the headers of each column, parse the line and dynamically generate the columns to the DataGrid control. Now I need a way to generate each Clotilde the DataGrid from the rest of the lines. The question that I'm struggling with (new Flex) is. I think I need to create an associative array of the form:

var asArray:Object = {col1: 'value1', col2: "Value2", etc.}

The problem is that all the column names in a table and each value is stored in another table. How to dynamically create a construction which will be

take me to represent a row in a DataGrid as described in EnTableau? In other words, is there a way to dynamically generate a statement like the one above?

Grateful for your help!

If I understand correctly, you are able to analyze all your data to two types of arrays:

var table: columns = {"column1", "column2",...}

var rowValues:Array = {, ",...}

So as you can see I guess that each value in rowValues table has light-emitting column name in the columns table. So you can build your 'associative' (in fact it is just a simple object) like this:

var rowObject:Object = new Object();

for (var i: int = 0; i< rowvalues.length;="" i++)="">

rowObject [GBA [i]] = rowValues [i];

}

The heart of the loop is the third line and the use of hooks on an object.

    Yes,

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

    Kind regards

    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

  • PLS-00201 when adressing field in an associative array

  • Associative array syntax

    I want to create an associative array, but using variables instead of coding hard.

    example of

    Instead of

    Assoc ['field1'] = data;

    I want to

    Assoc [fieldname] = data;

    I read for centuries and can't seem to find anything. I tried the above and it does not work.

    Any suggestions?

    Okay, I think that I managed to solve it. It seems to work although I don't know if maybe I've not initialized properly. I had a number of things wrong with the previous code. One was to have the push in the loop of passes and the other has changed the way to configure the array.

  • How to create dynamic arrays parallel/side-by-side in Adobe cycle

    Is it possible to create dynamic arrays parallel/side-by-side in Adobe cycle?  If so, how?

    Given that the tables have different sizes, in that I am running wrapping issues with running adjustment of Western characters and characters from the pagination with checkpoint.  Any other ideas?

    In fact, I had tried this solution ("wrapping the tables in a subform of position and set to automatically adjust the height and allow page breaks"), but it did not work.  Something to do with nested subforms of position within a subform control flow etc.  So to make it work, I set the page to be a subform of position and the auto-hauteur value and allow page breaks and I unpacked the paintings while they were only 'wrapped up' of the page itself.

  • Associative array of index files by varchar2 - PLS 00382

    I have a SQL anonymous block that creates a report. At the end of each section, I need to summarize the data by "renting". The list of locations is finished (approx. 15 in a table) and not all sections will have data for each location, but I want the locations to order the same so I thought I'd use an associative array to store summary data. But when I try to initialize the associative array (I simply put the slots in the array in the "correct" order) I receive PLS-00382 expression is of the wrong type.

    Here is the code (the lines where the error occurs are in bold):

    TYPE summary_data () IS RENDERING
    Summary1 NUMBER,
    NUMBER of summary2
    NUMBER of summary3
    );

    Summ_arr TYPE IS TABLE of summary_data INDEX OF VARCHAR2 (5);

    location_summary summ_arr;

    aLoc VARCHAR2 (5);

    PROCEDURE init_summ (aSummArr IN OUT summ_arr) IS
    BEGIN
    aSummArr.Delete;

    BEGIN
    FOR in aLoc (select name - name is VARCHAR2 (5))
    table
    control key)
    LOOP
    aSummArr (aLoc) .summary_1: = 0;
    aSummArr (aLoc) .summary_2: = 0;
    aSummArr (aLoc) .summary_3: = 0;
    END LOOP;
    EXCEPTION
    -exception handling
    END;

    END;

    If this is not allowed, or I do something wrong? I tried substituting:

    Summ_arr TYPE IS TABLE of summary_data INDEX OF VARCHAR2 (5);

    with

    Summ_arr TYPE IS TABLE of summary_data INDEX table.key%TYPE;

    Nothing helps.

    Thanks in advance for your help with this.

    ANNUAL GENERAL MEETING

    ALOC is a record variable. You need to refrence the column in the file said. So, something like this:

    aSummArr(aLoc.name).summary_1 := 0;

  • 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.

    You did not create a SQL type as I said. tbl_integer is still declared in the PLSQL code you have posted.

    Reread my initial response and look at the example I posted (the very first thing that is done is to create a SQL type).

  • An associative array in PL/SQL: key = varchar2, value = varray (varchar2)

    I'm doing an associative array, where the key is a string and the value is an array of strings.

    I tried to declare it like this:

    PROCEDURE myProcedure IS
    tableau_donnees argument type is varray (200) of VARCHAR2 (20);
    Column TYPE IS an ARRAY OF tableau_donnees INDEX BY VARCHAR2 (20);
    my_collection columns; -collection of multi dimensional pl/sql
    BEGIN
    my_collection ('test') (1): = "Hello"; -It is the idea...
    "my_collection ('test') (2): = ' 8128 is the number";
    my_collection ("some other field' ') (1): = 'foo';
    -etc etc.

    But I get the error Oracle ORA-06531, reference to an uninitialized collection:

    Cause: A service of element or member of a nested table or varray has been referenced (where an initialized collection is necessary) without the collection has been initialized.

    Action: Initialize the collection with an appropriate constructor or assignment of the whole object.

    I tried to use 'extend()' initialize the varray, but no help...
    my_collection('test').extend (200);

    -----
    I also tried this:

    PROCEDURE myProcedure IS
    Data TYPE of TABLE IS OF VARCHAR2 (20);
    Column TYPE IS an ARRAY OF data INDEX BY VARCHAR2 (20);
    my_collection columns; -collection of multi dimensional pl/sql


    But it's always the same. I am quite new to PL/SQL, if any help would be great!

    And if you want to add elements in varray:

    create or replace
  procedure myProcedure
    is
        type data_array
          is
            varray(200) of varchar2(20);
        type coltype
          is
            table of data_array
            index by varchar2(20);
        my_collection coltype;
    begin
        my_collection('test') := data_array('hello');
        my_collection('test').extend;
        my_collection('test')(2) := '8128 is the number';
        my_collection('some other field') := data_array('foo');
end;
/

    Or:

    create or replace
  procedure myProcedure
    is
        type data_array
          is
            varray(200) of varchar2(20);
        type coltype
          is
            table of data_array
            index by varchar2(20);
        my_collection coltype;
    begin
        my_collection('test') := data_array(); -- initialize
        my_collection('test').extend;
        my_collection('test')(1) := 'hello';
        my_collection('test').extend;
        my_collection('test')(2) := '8128 is the number';
        my_collection('some other field') := data_array('foo');

  • join an associative array with table

    I'm new to associative arrays.

    Here, I'm doing the equivalent of as follows:
     create table mytable as select n1,padding from T1 where rownum <=5;
Table created.
    And join this table with T1 and the corresponding records to get top 10
      1   SELECT * FROM
  2   (
  3     SELECT
  4              T1.n1
  5            , T1.small_vc
  6            , mytable.padding
  7      FROM
  8             mytable
  9            , T1
 10      WHERE
 11            mytable.n1 = T1.n1
 12   )
 13* WHERE ROWNUM <= 10;
    Now with the assicative bays
      1  DECLARE
  2          type array is table of T1%rowtype index by binary_integer;
  3          l_data array;
  4          l_rec T1%rowtype;
  5  BEGIN
  6          SELECT
  7                    *
  8          BULK COLLECT INTO
  9          l_data
 10          FROM T1
 11          WHERE ROWNUM <=5;   -- the top 5 records
 12          FOR i IN 1..l_data.count
 13          LOOP
 14                BEGIN
 15  --
 16               SELECT
 17                     *
 18               INTO
 19                     l_rec
 20               FROM
 21                     T1
 22               WHERE
 23                     T1.n1 = l_data(i).n1;
 24             EXCEPTION
 25               WHEN OTHERS THEN
 26                       DBMS_OUTPUT.PUT_LINE(to_char(SQLCODE) || ' - ' || substr(SQLERRM,1,200));

    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.
