  Hi all

  Currently I am working on Oracle 11 g

• How to remove duplicates from comma separated string

  
  Hi all

  I have an obligation to remove duplicates of string separated by commas:

  Some examples of code (real data can be in millions)

  {code}

  create table test_dup_del (num number (10), dup_val varchar2 (100));

  insert into test_dup_del values (1234, '1, 2, 3, 4, 3, 1');
  insert into test_dup_del values (4567,'1, 2, 2, 4, 4, 1');

• How to train a xml using a comma separated string in Xquery

  Hi all
  
  In my application, I need to write an Xquery query that should be an xml document. Admission to the XQuery function is an xml with an element that has the strings separated by commas. For
  
  example of
  
  < root >
  < StringComma > Hi, Hello, welcome < / StringComma >
  < / root >
  
  I need form an xml in such a way that it should have as many tags as the strings in < StringComma > element of the foregoing. For example, is what I want
  
  < Root1 >
  < String1 > Hello < / String1 >
  < String2 > Hello < / String2 >
  Welcome < String3 > < / String3 >
  < / Root1 >
  
  something like that. How could we do it using XQuery. Kindly help me in this.
  
  
  Thank you.

  Hello

  You can do it like this:

  Since you don't have 11 GR 2, making it a lot easier, I would use INSTR/SUBSTR to break the values, and then use START WITH / CONNECT BY to group the separate values of back together. I avoid the REGEXP stuff when I can because he uses a lot of CPU.

• Values separated by a nested as comma from string table

  I would insert the contents of a table nested in the form of comma-separated values in a string.
  
  
  For example, I created:
  
  CREATE TYPE u_results AS TABLE OF VARCHAR2 (10);
  /
  
  CREATE TABLE example_table)
  number of obj_id,
  obj_results u_results)
  NESTED TABLE obj_results STORE AS obj_results_t;
  
  INSERT INTO example_table (obj_id, obj_results) VALUES (1, u_results ('OK', 'NOK', 'NN'));
  INSERT INTO example_table (obj_id, obj_results) VALUES (2, u_results ('OK', 'NOK'));
  
  CREATE TABLE example_table2)
  number of obj_id,
  obj_results2 VARCHAR2 (100));
  
  So, in the example_table2 table I would have obj_results values in obj_results2 as string separated by commas.
  
  for example
  OBJ_ID obj_results2
  1 OK, NOK, NN
  2 OK, NOK
  
  Any ideas? Thank you

• Why the function of integrated separator string is missing in Oracle?

  Hi all

  It's maybe a generic/discussion question. And it's purely for learning about how Oracle prioritizes its development on the functions in construction.

  Well, we have very userful built-in functions (http://docs.oracle.com/cd/B19306_01/server.102/b14200/functions001.htm) is transformed during the versions of Oracle from simple to very complex (syntactic xml and data mining functions)

  But why is this important function to split a string has been neglected (may not be the right word) by Oracle.

  Be a learner curious and admirer of such a wonderful technology database called Oracle, I always thought that it must have a dedicated channel, divide the function.

  My question is: is this something that can be generalized in a built-in function?

  or

  Is he coming releases?

  At least a simple function first (I guessed right his name would be splitstr and the very basic features to do our job of splitting, maybe I'm wrong in thinking this way, please correct me if...) Thank you in advance!)

  splitstr('A,B,c',',','col')-> (separator ',' and the fractionating column mode)

  Output: A B C (three separate columns)

  splitstr('A,B,c',',','row')-> (separator ',' and the mode line split)

  Output:

  A

  B

  C

  ----------

  If oracle has this, there will be a lot of code reduced and we can be saved by connect or recursive with clause or as a matter of fact even xmltable (with or without tokenizer ) for the separation of the channels.

  What you have to say about this? You can ignore this naïve question if is not a value you answer.

  And thanks for everyone who reads this discussion!

  See you soon,.

  Manik.

  Can you please help me understand why Oracle has its participation in develping and DBMS_UTILITY.COMMA_TO_TABLE now then?

  http://docs.Oracle.com/CD/B19306_01/AppDev.102/b14258/d_util.htm

  Oracle can only tell you why they have developed this particular function. But the fact that Oracle included in a package of "utility" tells me that they do not consider that there was a generic number of use cases. These functions often begin as internal functions that Oracle decides to publish.

  But if you read this API spec you'll see that he does that to a VERY PARTICULAR use case and has several restrictions.

  The list must be a list separated by commas of non-vide: another thing that a comma-separated list is rejected. Do not count the commas inside double quotes.

  Entries in the list separated by commas may not include multibyte and dashes (-) character.

  Also, returns a collection which would normally be used only for a very limited number of items.

  It is not yet near a general-purpose function.

  A major complication with such a function in SQL is sql is generally used with more than one, or even millions, of lines.

  How you specify to Oracle where to put the collection on each of these lines?

  New - Oracle is a relational database. With the help of sql to manipulate collections is NOT a relational paradigm.

  Just my opinion. Others can and will disagree. But you may have to wait for the weekend for these answers.

• comma separator

  Hello

  In Oracle 10 g, I need to split comma separation like that.

  data:

  '1,3,2,3,4,6'

  to divide like this

  Col1 col2

  1        3

  2        3

  4        6

  Thanks in advance

  Hello 00125

  This might be a solution:

  WITH TMP_TAB

  AS (SELECT '1,3,2,3,4,6' AS DOUBLE TXT)

  SELECT REGEXP_SUBSTR (txt, ' [^,] +', 1, 2 + 1 *(level-1)) AS Col1

  REGEXP_SUBSTR(txt, '[^,]+', 1, 2*level) AS Col2

  OF TMP_TAB

  CONNECTION OF level <= round((length(txt)="" -="" length(replace(txt,="" ',')))="" 2) ="" --="">10g characteristic

  ;

  Less than 11g, you can write it's simpler:

  CONNECTION OF <= regexp_count(txt="" ||="" ',',="" ',')="" 2 ="" --="">11g characteristic level

  I hope it helps.

• The research of a column with comma separated values with ora-text

  I use the Oracle 11 g 2 XE and Oracle Text to a web search engine.
  
  I've now created and text indexed a CLOB keywords column that contains words separated by spaces. This allowed me to expand the search, as Oracle Text returns the rows that have one or more keywords that are stored in this column. The contents of the column are visible to the user and serves to 'expand' the search. This does not work as expected.
  
  But now I need support several words or even sentences. With the current configuration, Oracle Text will only search for each keyword. How should I store the phrases and configure Oracle text so that it will search entire sentences (exact match is better, but the partial match is fine too)?
  
  Example of content column of two lines (values separated semicolon):
  "Hello, Hello; y at - it anyone out there? Nope; »
  "the just; basic facts; »
  I found a similar question: looking for a column with values separated by commas, except that I need a solution for Oracle 11 g with it's freetext search.
  
  Possible solutions:
  1st solution: I thought to redraw the DB as follows. I would like to make a new array of keywords (pkID NUMBER, nonUniqueID NUMBER, singlePhrase VARCHAR2 (100 BYTE)). And I want to change the column previous keyword to KeywordNonUniqueID, holding the ID (instead of a list of values). At the time of the research I had INNER JOIN with the new keyword table. The problem with this solution is that I will get several lines containing the same data except for the sentence. I guess this will destroy the ranking?
  
  2nd solution: is it possible to store sentences as an XML in the column key of origin and somehow say Oracle text to search for in the XML?
  
  3rd solution: separate individual phrases with spaces, but replace the spaces in sentences with the underscore or something (making a single word). If a phrase "why Hello there, Johnny!" is saved as "Why_hello_there, _Johnny!
  
  4th solution?:
  
  Note that, generally, there is a lot of sentences (less than 100), nor that they will be long (one sentence will be up to 5 words).
  
  Also note that I am currently using CONTAINS, and needs some of its operators, to my full-text searches.

  When you talk about "phrase", do you mean "a list of words separated by a comma other sentences?

  Isn't that the definition of "sentence" used by Oracle Text, where it simply means "a list of words in the order defined."

  If I understand your requirement, you want to have data such as:

  "aa bb cc dd".
  "aa ee dd ff.

  and give priority to the first on the second if someone looking for "dd".

  First, to conduct research in the comma separated list, you should look for in a section. You can either explicitly define sections of field such as
  AA bb cc dd
  Or you can use the PHRASE special section and set the sentence delimiters correctly. This is done with the attribute BASIC_LEXER punctuation

  Then you have the number you want to find only words where they are the only words in the section. That's the same problem, I address in the last post of this forum entry:
  Contains: match exactly

  Our solution will be substantially the same, some surrounding text with special markers, and then prioritize a phrase search with these special markers each side of the word.
  We need to do a treatment some additional, although, as we need to surround each "sentence" (in your terminology) with special markers. I did it by surrounding the text with "XX1"... Condition2"then by replacing every comma with"Condition2, XX1"as part of a MULTI_COLUMN_DATASTORE:

  drop table names;
  create table names (id number primary key, text varchar2(50));
  
  insert into names values( 1, 'just and kind, kind and loving' );
  insert into names values( 2, 'just, kind' );
  
  exec ctx_ddl.drop_preference  ( 'mylex' )
  exec ctx_ddl.create_preference( 'mylex', 'BASIC_LEXER' )
  exec ctx_ddl.set_attribute    ( 'mylex', 'PUNCTUATIONS', ',' )
  
  exec ctx_ddl.drop_preference  ( 'mcds' )
  exec ctx_ddl.create_preference( 'mcds',  'MULTI_COLUMN_DATASTORE' )
  exec ctx_ddl.set_attribute    ( 'mcds', 'COLUMNS', '''XX1 ''||replace(text, '','',''XX2, XX1'')||'' XX2''' )
  
  exec ctx_ddl.drop_preference  ( 'mywl' )
  exec ctx_ddl.create_preference( 'mywl', 'BASIC_WORDLIST' )
  exec ctx_ddl.set_attribute    ( 'mywl', 'SUBSTRING_INDEX', 'YES' )
  
  create index namesindex on names(text)
  indextype is ctxsys.context
  parameters( 'datastore mcds wordlist mywl' )
  /
  
  select score(1),id,text from names where contains( text, '
  
    
      
         XX1 kind XX2 
         kind
      
    
  
  ', 1) > 0
  order by score(1) desc
  /
  

  Output of this is:

• SQL - Multiple Fetch in a single column with a comma separator

  Hello Experts,
  Good day to all...
  
  I need your help on the following scenarios. The following query returns all channels titleID. Rather than print them one under the other as a result of the query, I want the output to be in the batch of 25 values.i.e than each line must have 25 values separated by commas. IE if there are 100 titles satisfying the output, then there should be only four lines with and each line with 25 titles in comma separated way.
  

  SELECT DISTINCT title_id

• Combine several values of rank in a line like comma delimeted string

  Hello
  
  I have a requirement to combine several values of rank in a line as the comma delimeted string as below
  
  INDEX_NAME COLUMN_NAME POSITION_COLONNE
  EMP_EMAIL_UK EMAIL 1
  EMP_EMP_ID_PK EMPLOYE_ID 1
  EMP_DEPARTMENT_IX DEPARTMENT_ID 1
  JOB_ID EMP_JOB_IX 1
  EMP_MANAGER_IX MANAGER_ID 1
  EMP_NAME_IX LAST_NAME 1
  EMP_NAME_IX FIRST_NAME 2
  I write in a SQL and the output I need is, for example EMP_NAME_IX LAST_NAME, FIRST_NAME.
  
  I can't write any function as well.

  SELECT index_name,
         ltrim(sys_Connect_by_path(column_name, ','), ',') column_names
    FROM (select index_name,
                 column_name,
                 row_number() over(partition by index_name order by column_position) rn

• looking for a specific string in a comma separated column

  I have a column of table called content that shows the following values.
  
  Content ID
  = ====
  1 jkl, abc, def, xyz
  2 jkl
  3 jklm, xyz
  4 abc
  
  I need to write a sql statement to find all records that has 'jkl', the result I want is 1 and 2. Any suggestions?
  
  Thank you.

  Something like

    with t1 as (
    select 1 id, 'abc, jkl, def, xyz' content from dual
    union select 2, 'jkl' from dual
    union select 3, 'jklm, xyz' from dual
    union select 4, 'abc' from dual)
    select id
      from t1
    where ', '||content||',' like '%, jkl,%';
  

  You can avoid record 3

  Now, it should work!

• Split comma delimited string CONNECT BY Clause

  Hello
  I had a problem by dividing a strings separated by commas into lines.
  
  I explain the following use cases:
  
  I have an x in table
  -> create table x (id number, int_status varchar2 (100), c_ref varchar2 (30), s_ref varchar2 (30));
  
  I inserted values in the table:
  
  insert into x (id, int_status, c_ref, s_ref) values (1, 'a1, a2, a3, a4 ', 'A',' AS');
  insert into x (id, int_status, c_ref, s_ref) values (1,'b1, b2, b3, b4 ',' B', 'BS');
  insert into x (id, int_status, c_ref, s_ref) values (1,'c1, c2, c3, c4 ", 'C', null);
  insert into x (id, int_status, cust_ref, site_ref) values (1, NULL, would be ', NULL);
  
  
  I need to split the int_status separated by commas into individual lines. This means that my result is:
  
  . What I need or are looking as expected result:
  -----------
  1, has, HAVE, a1
  1, has, HAVE, a2
  1, has, HAVE, a3
  1, has, HAVE, a4
  1, B, BS, b1
  1, B, BS, b2
  1, B, BS, b3
  1, B, BS, b4
  C, 1, null, c1
  C, 1, null, c2
  C, 1, null, c3
  C, 1, null, c4
  
  I currently have a solution using Regex. But this solution uses the UNIQUE keyword.
  
  The solution that I currently have:
  
  Select UNIQUE c_ref, s_ref, regexp_substr (int_status, "[^,] +', 1, level") error_code
  x
  connect regexp_substr (int_status, "[^,] +', 1, level") is not null;
  
  
  I need a better solution. Pointers?
  
  Thank you

  Hi Omar,.

  I mentioned the solution of Odie for similar problem some time ago...
  and in my opinion the easiest to solve your task would be:

  SELECT id,c_ref,s_ref,str error_code
    FROM x_imp,
         XMLTABLE ('ora:tokenize($v, ",")'
                   PASSING int_status AS "v"
                   COLUMNS str VARCHAR2 (12) PATH '.');
  

  output:

  ID     C_REF     S_REF     ERROR_CODE
  1     A     AS     a1
  1     A     AS     a2
  1     A     AS     a3
  1     A     AS     a4
  1     B     BS     b1
  1     B     BS     b2
  1     B     BS     b3
  1     B     BS     b4
  1     C          c1
  1     C          c2
  1     C          c3
  1     C          c4
  

  See you soon,.
