  Hi, Tobias,.

  This can be more efficient, because it does not use CONNECT BY or regular expressions. Instead of splitting the string to the level of every comma, just find the target string and count how many commas occur in front of her.

  WITH     got_found_pos          AS
  (
       SELECT     list_txt
       ,     INSTR ( ',' || list_txt || ','
                  , ',bambi,'
                  )          AS found_pos
       FROM    table_x
  )
  SELECT     list_txt
  ,     found_pos + 1
              - LENGTH ( REPLACE ( SUBSTR (list_txt, 1, found_pos)
                                    , ','
                           )
                    )          AS item_num
  ,     found_pos
  FROM    got_found_pos

  Delimited lsits storage is usually a bad idea in a relational database. It is best to store each item in the list on a separate line.

• Problem using the list separated by commas with nested table element

  Hello
  
  I have a list separated by commas like this:

  H23004,H24005,T7231,T8231,T9231

  And want to create a function that creates a where clause clause for each element with an output like this:

  UPPER('H23004') IN (UPPER(charge))
  OR UPPER('H23005') IN (UPPER(charge))
  OR UPPER('T7231') IN (UPPER(charge))
  OR UPPER('T8231') IN (UPPER(charge))
  OR UPPER('T9231') IN (UPPER(charge))

  Here's my test function that is not working properly:

  create or replace function FNC_LIST_TO_WHERE_CLAUSE(v_list in VARCHAR2) return varchar2 is
   -- declaration of list type
   TYPE batch_type IS TABLE OF pr_stamm.charge%TYPE;
   -- variable for Batches
   v_batch batch_type := batch_type('''' || replace(v_list,',',''',''') || '''');
   return_script varchar2(1000);
  
   BEGIN
   -- loop as long as there are objects left
   FOR i IN v_batch.FIRST .. v_batch.LAST
   LOOP
     --DBMS_OUTPUT.PUT_LINE(offices(i));
     -- create where clause
     IF i = 1 THEN
       return_script := 'UPPER(' || v_batch(i) || ') IN (UPPER(charge))';
     ELSE
       return_script := return_script || ' OR UPPER(' || v_batch(i) || ') IN (UPPER(charge))';
     END IF;
   END LOOP;
  
   return (return_script);
   end;

  The out put looks like this:

  UPPER('H23004','H24005','T7231','T8231','T9231') IN (UPPER(charge))

  I don't know what I did wrong? It calculates the amount of the incorrect array element! (v_batch. Must be 5)
  v_batch. FIRST = 1
  v_batch. LAST = 1
  
  Kind regards
  
  Tobias

  Try this...

  declare
  text varchar2 (1000): = "H23004, H24005, T7231, T8231, T9231;

  text: = substr (text, instr(text,',',1) + 1);

• REGEXP_SUBSTR for the list delimited by commas with null values

  Hello
  
  I have a column that stores a list of values comma-delimited. Some of these values in the list may be null. I'm having some trouble trying to extract the values using the REGEXP_SUBSTR function when null values are present. Here are two things I've tried:

  SELECT
     REGEXP_SUBSTR (val, '[^,]*', 1, 1) pos1
    ,REGEXP_SUBSTR (val, '[^,]*', 1, 2) pos2
    ,REGEXP_SUBSTR (val, '[^,]*', 1, 3) pos3
    ,REGEXP_SUBSTR (val, '[^,]*', 1, 4) pos4
    ,REGEXP_SUBSTR (val, '[^,]*', 1, 5) pos5
  FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);
  
  POS P POS P P
  --- - --- - -
  AAA   BBB

  SELECT
     REGEXP_SUBSTR (val, '[^,]+', 1, 1) pos1
    ,REGEXP_SUBSTR (val, '[^,]+', 1, 2) pos2
    ,REGEXP_SUBSTR (val, '[^,]+', 1, 3) pos3
    ,REGEXP_SUBSTR (val, '[^,]+', 1, 4) pos4
    ,REGEXP_SUBSTR (val, '[^,]+', 1, 5) pos5
  FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);
  
  POS POS POS POS P
  --- --- --- --- -
  AAA BBB DDD FFF

  As you can see that neither calls work correctly. Anyone know how to change the regular expression pattern to handle null values? I tried various other models but could not get anyone to work in all cases.
  
  Thank you

  Hi, Martin,.

  That's what you want:

  SELECT
     RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 1), ',') pos1
    ,RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 2), ',') pos2
    ,RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 3), ',') pos3
    ,RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 4), ',') pos4
    ,RTRIM (REGEXP_SUBSTR (val || ','
                        , '[^,]*,', 1, 5), ',') pos5
  FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);
  

  The query above works in Oracle 10 or 11, but in Oracle 11, you can also do it with only REGEXP_SUBSTR, without using RTRIM:

  SELECT
     REGEXP_SUBSTR (val, '([^,]*),|$', 1, 1, NULL, 1) pos1
    ,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 2, NULL, 1) pos2
    ,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 3, NULL, 1) pos3
    ,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 4, NULL, 1) pos4
    ,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 5, NULL, 1) pos5
  FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);
  

  The problem with your first request was that he was looking for sub channels of 0 or more non-virgules. There was as a substring. consisting of 3 characters starting at position 1, he returned "AAA", as expected. Then there was an another substring, the 0 characters, starting at position 4, so it returned NULL. Then, there was a substring of 3 characters starting at position 5, so he returned 'BBB '.

  The problem with your 2nd request was that he was looking for 1 or more non-virgules. 'DDD' is the 3rd this substring.

• list separated by commas - extraction of each element in an array?

  Is there a quick way to make a field that contains a list of items separated by commas and put them in a table or perhaps separate variables?

  for example.

  a single line in the database contains the field [matches_with] and would generally contain the following elements:

  rings, bracelets, necklaces

  I need to be put in a variable

  < cfset item1 = 'rings' >

  < cfset item2 = 'bracelets' >

  < cfset item3 = necklaces >

  or if its more simple, put them in a table

  agenda [1] = 'rings '.

  point [2] = "bracelets".

  point [3] = "necklaces."

  There is a built-in ListToArray function to CF.

• Count the items in a single list or table

  I use a multiple selection in MX list control. I can get a simple list of the selected items, but when I try to determine the number of items is selected, I get an empty return value.

  Here is the code I use:

  selectedItems = .selectedItems sprite (19)

  selectedCount = selectedItems.count

  After that the first call returns, selectedItems contains an array of two objects. Each object contains two field (data and label). The call of the County always returns void. I tried selectedItems.count () which indicates that both parameters are mandatory and another every permutation I can think.

  What is the secret to count the number of items in a list?

  Your problem is perhaps that the returned object is an object AS and not a list (jargon). What happens if you try

  selectedCount = selectedItems.length

  You do not want a list separated by commas. You want to move a collection. Then

  CREATE TYPE num_tbl
  AS
  TABLE OF NUMBER;
  
  DECLARE
    l_list_of_ids num_tbl := num_tbl( 10, 20, 30 );
  BEGIN
    ...

• How to set the value of the box check the plug-in in session state using a DA

  I tried the code proposed to

  Paul, in fact, you can use a dynamic Action.

  Say your question change event, say P1_CHECKBOX.

  So here's the clincher.

  Action: execute the PL/SQL Code

  PL/SQL code:

  Start

  null;

  end;

  Page to submit items: P1_CHECKBOX

  That's all.

• Export data from Oracle table to a .csv file by putting a condition on the value of a column

  Hello gurus,

  My output should look like

  1,Oracle,12.1,12/28/2013

  1,Oracle,10.2,06/12/2010

  Here, I want to pass the value as a parameter dynamically

  Can someone help me with the sql/plsql.

  || ',' || version_col

  || ',' || To_char (date_col, 'HH24:MI:SS of Mon-DD-YYYY') AS csv_text

  from your_table

  where rowid_col IN (& input_values);

  then & input_values can be a unique number (e.g. 1) or a list separated by commas (for example, 1,2,3) numbers.  Don't put NO space around the comma.
