  The title you chose for this thread is "inner join is not eliminating duplicates!
  Inner joins (or other types of joints) are not supposed to remove duplicates. Use SELECT DISTINCT to remove duplicates, which is exactly the same lines.
  You don't have to duplicate. For example, these lines of your result set:

  `        CNAME     CNAME
  1     Perira     Hoffman
  10     Hoffman     Perira
  

  are not identical; Indeed, the two columns are different.

  Ideally, it should up to 5 rows, but it does not return these lines for an e.g. Hoffman perish since I'm Perira Hoffman already.

  Please report the exact output of the sample data you want. (As said by Hoek, post CREATE TABLE and INSERT statements for the sample data too.)

• 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');
  insert into test_dup_del values (7894,'1, 2, 1, 3, 3, 1');

  insert into test_dup_del values (2589, '1, 2, 1, 2, 1, 2');
  commit;

  (code}

  my output would be:

• Structure from case string "&lt;------"-LabVIEW converts the string

  Hello

  I want to parse the string lines read from a data file.  Some chains start with the characters ".<\".  when="" i="" enter="" this="" kind="" of="" string="" as="" a="" case="" in="" a="" case="" structure="" the="" string="" is="" being="">

  For example, I'm going home. "<\C" (upper-case="" c)="" as="" my="" case="" string,="" it="" changes="" to=""><\f".  if="" i="" enter=""><\c" (lower-case="" c)="" as="" the="" string="" it="" becomes="">

  I am currently using LabVIEW 2012.

  Any ideas what's happening?

  Thank you

  Ian

  Some ASCII characters are nonprinting control characters (less than 32 values). These are sometimes encoded using the backslash code and it seems that is what makes the structure of matter - when you type \C, the structure of the performer as "oh, you want the value 0x0C ASCII, which in the code for backslash is represented" as \f (means 'form feed). "When this is the case, you typically use one-to represent the------characters, so you really need set the structure to match on.<>

• How can I get rid of duplicates from folder?

  I have a HP Win 7 system that I bought in November 2009. I moved all the backed up files, I created a Vista system and saved on an external hard drive and put them in the appropriate in Win 7 folders. Along the way, about a month or two ago, the 'My music' folder decided to duplicate himself in the folder "my pictures." Anything to be added or removed from rehearsals in the other folder as well. I want to delete the one in "My pictures", such that it caused all kinds of freeze ups when you do something in there, caused by the activation of Windows Media Player to go online and search for updates file. This makes any process to become unusable as all the system waits for WMP let go of his prey. It must be the folder the file images who created this music. If I download a clean folder, empty, newly created, the problem does occur.

  Also, when I try to delete one or the other, or move them, it gives a message stating: "the action cannot be performed because the file or the file is open in another program. Close the folder or file and try again. »

  Sometimes even if the Task Manager shows only one of them open at the time of the attempt to remove.

  Hello

  Recent changes on your computer?

  Try the process for my music and my pictures folders (Windows 7 it's just music and images) below.

  2. click the default button.

• Remove duplicates from the oracle table using 2 columns

  Hello

  I need to remove the duplicates of an oracle table based on 2 columns in the table.i tried to remove duplicates using the join, but get the error like sql error ora-00933

  Thank you

  Hello

  Here's one way:

  DELETE FROM table_x

  WHERE ROWID NOT IN)

  SELECT MIN (ROWID)

  FROM table_x

  Col_1, col_2

  );

  I hope that answers your question.

  If this isn't the case, please post a small example data (CREATE TABLE and only relevant columns, INSERT statements), and the results you want from this data.

  In the case of a DML operation (for example, REMOVE) the sample data should show what look like the paintings before the DML, and results will be the content of the or the tables changed after the DML.

  Explain, using specific examples, how you get these results from these data.

  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

  See the FAQ forum: Re: 2. How can I ask a question on the forums?

• Removing spaces from a string

  I have a string where there is a particular sequence, I want to replace.

  The sequence is ' / p e r.

• Extract the string from the string

  Hello guys,.

  I have a small question. I would like to extract a string to another string. Imagine the following string:

  param1 = value1 param2 = value2, param3 = value3, param4 = value4

  I would like to be able to extract value2 and value3 to this string. I know that the design of the db is not perfect and should be like this. but it is historical and I have to use this way. Any suggestion?

  Thank you

  to retrieve param2

  Select

  substr (s

  , instr (s, '=', 1, 2) + 1

  , instr (s, ',', 1, 2) - instr (s, '=', 1, 2) - 1

  ) r

  from (select "param1 = value1 param2 = value2, param3 = value3, param4 = value4's double)

  or

  Select regexp_substr (your_string, "[^,] +' 1, 4") from your_table

  for example

  Select regexp_substr ("param1 = value1 param2 = value2, param3 = value3, param4 = value4 ',' [^,] +' 1, 4") param2 double

• REGEXP_REPLACE return strange results and eliminating duplicate characters

  SELECT REGEXP_REPLACE(p_str,'[^[:digit:]][^[:alpha:]]','.') FROM (SELECT 'AAA bb' double p_str);

  > AA.bb

  I hope that answers your question.
  If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) and also publish outcomes from these data.
  If you ask a DML statement, such as DELETE, the sample data will be the content of the or the tables before the DML, and the results will be the State of the or a modified tables when it's all over.
  Explain, using specific examples, how you get these results from these data.
