[JS] Adding methods to associative arrays

• Associative array declaration Inline?

  I would like to declare an associative array with the keys based on the constants using the method inline.

  The documentation shows inline declarations of associative array as follows:

  var assocArray:Array = {key: "value", key2: "Value2", key3: "Value3"};

  the problem here is that the following does not work:

  var assocArray:Array = {this.const1: "value", this.const2: "value2", this.const3: "value3"};

  To work around this problem, I had to do the following so far:

  var assocArray:Array = new Array();

  assocArray [this.const1] = 'value ';

  assocArray [this.const2] = 'value2 ';

  assocArray [this.const3] = "Value3";

  How can this be done online?

  It cannot be done online.

• Add items to an associative array

  I would like to add items at the end of an associative array. The approach I take is this:
  

  myArray(myArray.LAST + 1) = <some_value>

  Is there a better way to do it? As with a kind of method?

• Associative array question

  Hi all
  
  I searched through this forum trying to find I need information about the associative arrays with an index of varchar2 without success. What I'm looking for is a way to get the index or the 'key' values in the table without knowing what they are. Which means, I wouldn't know the index value in the design of the table, but would be able to use the values during execution. For those who are familiar with Java, it would be like calling the method keySet() of a map object.
  
  So if I have a table of TYPE COLUMN_ARRAY IS TABLE OF VARCHAR2 (4000) INDEX OF VARCHAR2 (100) is it possible to dynamically get the index values without knowing what they are?
  
  Any help is appreciated.
  
  Thank you

• How to: compare 2 associative arrays element-by-element

  After playing, I decided to go with the approach of the two sets of data of their own associative array.  The code and the results of this are below.  My question is the comparison.  For each element within the matrix of order, check all the items in the details table to see if there's a football game.  If there is a match > > > move to the next item in the control panel and check all the items in the details table to see if there is a football game.  Go until the whole is considered to be a match (in number of rows and values).  If no match, take the exit.

  Below, you'll see my logic to get both sets of data into their respective tables.  The results with a note attached to one of the elements is also pasted here (hereinafter the code).

• 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 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

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

  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

• 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.
