  The area of the stored products the list separated by commas in the names of products, which the company deals in.
  
  I want to know the number of companies for each product and organize the product list in descending order of their number
  
  For example, the sample data as follows
  
  The company produced ID
  1 a readers of portable barcode of desktop computers, the readers of barcodes, computer laptop, system memory,
  2B Handcrafted Wallets leather, holders of credit card in leather, handbag leather, ladies handbag, Designer handbag
  C 3 laptops, desktops
  4 d, leather wallet, handbag ladies
  5 E ladies handbag, ladies, ladies Sandals boots
  6 F designer handbag, handbag ladies
  
  Now, here's the result I want

  Hello

  [This thread | http://forums.oracle.com/forums/thread.jspa?threadID=717813&tstart=25] shows how to split a delimited (like your products column) parts list, one line per element.
  There is a solution for Oracle 9. In Oracle 10 (and more) that the solution (using SUBSTR and INSTR) will still work, but I recommend to use

  REGEXP_SUBSTR ( products
                , '[^,]+'
                , 1
                , n
                )  AS product
  

  Instead, to get the item of the n - th from the products in the list separated by commas.

  Once you have divided the column of the goods in parts, the main request is just

  SELECT    product
  ,         COUNT (*)  AS no_of_companies
  FROM      subquery
  GROUP BY  product
  ORDER BY  no_of_companies  DESC
  ,         product;

  Create list of patches in a table and use an outer join:

  with patch as (
                 select 111 patch,to_date('1-Jan-10','dd-mon-rr') applied_date from dual union all
                 select 222,to_date('1-Feb-10','dd-mon-rr') from dual union all

• Need help to write to Oracle and SQL Server in the Oracle triggering

  We have a third which feeds data for us. Their client application feeds directly to some source tables in our Oracle database 10g. We have triggers on those tables that sort and treat lines as they come.
  
  We have a new operation and try to write some of these incoming data now to a SQL Server database through heterogeneous services - essentially the same exact data in two databases. I have a related database that works very well for the selection, but I've never tried to write Oracle PL/SQL to write in a DB SQL Server 2008. My first attempt was met with the following error: "ORA-02047: impossible to join the current distributed transaction.
  
  I found another thread where they say that the only way to do it is by using a stand-alone transaction, but they do not give an example. Here is the section of relaxation that I use:

    select to_char(new_date,'MM-DD-YYYY') into sql_txt from dual;
    insert into mancamp_location@sqlweb
         ("UnitID", "ManCampID", "Lat", "Long", "UpdateDT", "VehSpeed", "VehDirection", "Landmark")
      values (v_truck, f_unit, f_lat, f_long, sql_txt, f_spd, f_dir, f_ldmk);

  Can someone point me to a way to accomplish this simple insertion?

  An example of a standalone trigger is:

  Suppose you have a table in Oracle:

  CREATE TABLE emp_sal
  (
  EMPNO NUMBER 4,
  SAL NUMBER (7.2));

  and a similar table in a SQL server:
  SQL Server:

  CREATE TABLE emp_sal
  (
  EMPNO NUMERIC (4).
  SAL NUMERIC (7.2));

  Then, you can create an insert trigger that replicates the data:
  CREATE OR REPLACE TRIGGER dg4odbc_repl AFTER INSERT ON emp_sal
  FOR EACH LINE
  DECLARE
  PRAGMA AUTONOMOUS_TRANSACTION;
  BEGIN
  INSERT INTO 'emp_sal"@MSODBCSQLSERVER_DG4ODBC_EMGTW_1123_DB '.
  VALUES (: new.empno,: new.sal);
  COMMIT;
  END;
  /

  -Note the validation, otherwise risk of ORA-6519

  When you now insert a record into the Oracle database:
  insert into emp_sal values (1234, '1200,89');
  the trigger is activated and inserts the record in SQL Server:
  Select * from 'emp_sal"@MSODBCSQLSERVER_DG4ODBC_EMGTW_1123_DB;
  EMPNO, SAL
  ----- -------
  1234 1200.89

  It works fine when you post data insert, but as soon as restore you the insert only data Oracle will be cancelled - data will remain as long as the independent transaction dedicated to its SQL Server insert:

  insert into emp_sal values (1384, '1200,89');
  Rollback;
  Select * from emp_sal;
  EMPNO, SAL
  ----- -------
  1234 1200.89

  Select * from 'emp_sal"@MSODBCSQLSERVER_DG4ODBC_EMGTW_1123_DB;
  EMPNO, SAL
  ----- -------
  1234 1200.89
  1384 1200.89

  So I strongly recommend to use the DG4MSQL gateway which is able to participate in distributed transactions and allows validation/restore transactions.

  DG4ODBC lie on OTN (http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html-online check out the "See all" link for your favorite platform), cloud of delivery of software Oracle (https://edelivery.oracle.com/) or "My Oracle Support". My Oracle support welcomes the latest version 11.2.0.3. In My Oracle Support goto patches and updates, then search for 11.2.0.3 data set Patch 10404530patch: 11.2.0.3.0 PATCH SET for ORACLE database SERVER, choose your preferred platform and see the Readme which CD contains the gateway software.

• Need help on the regular expressions and query

  Hi guru s, I hope that you all made great!
  
  I have a scenario where I need to insert data into the table.
  
  I have three scenarios:
  

  select 'Kodali,Raj,S' str from dual
  union 
  select 'Alex Romano' from dual
  union 
  select 'ppppp' from dual
  
  Alex Romano
  Kodali,Raj,S
  ppppp

  What I want is now.
  
  1 Alex Romano
  is there space between the chain and then I want to insert in the last name and first name columns
  2 Xavier, Raj, S
  If there is a comma between the chain and I want to insert in the last name, first name and middle name
  3. If there is one channel then insert even in first name and last name.
  
  I wrote the request more early to manage only by commas and now I'm trying but not able to use this all scenarios
  Can you please help me.
  

  WITH t AS (
   
  select 'Kodali,Raj,S' str from dual
  union 
  select 'Alex Romano' from dual
  union 
  select 'ppppp' from dual

     FROM   t
    CONNECT BY regexp_substr(str,'[^,]+',1,level) IS NOT NULL
    GROUP BY str
  ) ;

  Currently I put a b and c if its null value.
  
  
  Thanks in advance!

  Hello
  You can do what you asked for in pure SQL like this:

  WITH     got_pos          AS
  (
       SELECT     str
       ,     INSTR (str, ',')     AS comma_pos
       ,     INSTR (str, ' ')     AS space_pos
       FROM     t
  )
  SELECT    str
  ,       CASE
             WHEN  comma_pos > 0
             THEN  REGEXP_SUBSTR (str, '\w+', 1, 2)
             WHEN  space_pos > 0
             THEN  SUBSTR (str, 1, space_pos - 1)
             ELSE  str
         END     AS fname
  ,       CASE
            WHEN  comma_pos > 0
            THEN  REGEXP_SUBSTR (str, '\w+', 1, 3)
            ELSE  TRIM (REGEXP_SUBSTR (str, ' \w+ '))
         END     AS mname
  ,       CASE
             WHEN  comma_pos > 0
             THEN  SUBSTR (str, 1, comma_pos - 1)
             ELSE  REGEXP_SUBSTR (str, '\w+$')
         END     AS lname
  FROM       got_pos
  ORDER BY  str
  ;
  

  But look how it is difficult, even for this simple example of data.

  I suggest you write a PL/SQL function to analyze the name. It will be much easier to deal with a combination of spaces and commas, the names of more than 3 words, etc.

• Need help to write sql query

  I am trying to write the SQL for a single recordset.

  I have a table with all the info from the standard article and an item_colorID.

  I have a table with 2 columns, item_colorID and color_ID color_lookup

  I have a table with 2 columns, color_ID colors and color

  I want to join the tables and filter it so that a repeat region shows dynamic data by the name of article, thumb, description, price

  and also a dynamic list/menu populated by color

  filtered so that each element is in the list/menu only available element colors.

  I have tried different variations of this sql

  SELECT * items INNER JOIN color_lookup ON color_lookup.item_colorID = items.item_colorID INNER JOIN colors ON colors.color_ID = color_lookup.color_ID WHERE items.itemCatID = 3 ORDER BY items.itemName

  but the list/menu shows each color choice, multiplied by the number of items in this color

  That is to say white will show 80 + times.

  Thanks for your help,

  Jim balthrop

  Hi JB, I think I understand the situation, but of course, I'm not familiar with the interface of the cart software you are using. It seems that you will not be able to use the choice "research from the recordset" because the color is a different Recordset. You can't really understand the color in the main recordset because it would cause the main repeating region show the item once for each available color, which is not what you want.

  I also see that the drop-down color is in its own form. If you have placed this process in the main form, would be the behavior recoginize it and treat it differently? In other words, the cart accepts entry options outside the main form element it uses:

  I don't know that the shopping cart software contains other methods to add to the cart you can be forced to use.

  What shopping cart software are you helping? They have a forum which you could get more targeted assistance?

• need help to write sql code

  Hi all

  I need to write a sql that retrieves data from the status table and check for this time in the ESHIFT table if the flag was or not. If is there, then it will keep the record as it is Furthermore, there

  did not understand at the time the flag was N suppose ESHIFT table has one record where you N 13:00:01-13:30 then the status register which is 13:00-13:59 min 59 s, we should get 13:00 - 13: records of 00:00 1 and 2 of 13:30:01-13:59 min 59 s

  create table ESHIFT (From_date date, date, to_date, flag varchar2 (2));

  insert into ESHIFT values (' 1 February 12 09:00 ", February 1, 12 13:20 ', 'Y');

  insert into ESHIFT values (' 1 February 12 13:20:01 ", 1 February 12 13:30 ',' don't);

  insert into ESHIFT values (' 1 February 12 13:30:01 ", February 1, 12 16:00 ', 'Y');

  SELECT * from eshift;

  create table status (date of From_date, to_date date, status number);

  insert into values of status (1 February 12 11:00 ', February 1, 12 12:00 ', 1);

  insert into values of status (1 February 12 12:00:01 ', February 1, 12 12:20 ', 2);

  insert into status values ("1 February 12 12:20:01", 1 February 12 12:59:59 ', 1);

  insert into status values ("1 February 12 13:00", February 1, 12 13:59:59 ', 1);

  insert into status values ("1 February 12 14:00", February 1, 12 14:59:59 ', 2);

  SELECT * STATUS;

  In the case above should get sql

  1 FEBRUARY 12 11:00 1ST FEBRUARY 12 12:00 1

  FEBRUARY 1ST, 12 12:00 1ST FEBRUARY 12 12:20 2

  FEBRUARY 1ST, 12 12:20:01, 1 FEBRUARY 12 12:59:59 1

  FEBRUARY 1ST, 12 13:00 1ST FEBRUARY 12 13:20 1

  FEBRUARY 1ST, 12 13:30 1 FEBRUARY 12 13:59:59 1

  It will be really great if someone can help me how I can get the desired result.

  Thank you very much in advance.

  Please provide instructions creating table and data. It makes it so much easier to answer.

  I think you want:

  Select (s.from_date, e.from_date) greatest from_date, less (s.to_date, e.to_date) to_date, s.status

  s status e eshift join on s.from_date < e.to_date="" and="" s.to_date=""> e.from_date and e.flag = 'Y '.

• need help to write a conditional query recordset

  I have two fields or not in the database. VeteranMarker and VeteranNoMarker. Answering one can be Y or N.
  I want to write a statement for my detail page where there is a label "veteran? If VeteranMarker or VeteranNoMarker has a Y in the database, then I want to display "YES" next to the label of "veteran? If neither has a Y, then I want to say 'NO '.
  
  The recordset is called DetailRS1, the fields would be so (I think) DetailRS1.VeteranMarker and DetailRS1.VeteranNoMarker.
  
  I have no idea how to write a conditional statement to achieve this.
  
  Thanks in advance,
  Miriam

  I think I have it solved. Here is the code, and it seems to work. If this is correct, I hope it can help someone else too.

• Need help to write a MySQL query that returns only the peer matching records

  Because I don't know how to explain it easily, I use the table below as an example.
  
  I want to create a MySQL query that returns only the records that match counterparts where 'col1' = 'ABC '.
  
  Notice the ' ABC / GHI' record does not have a Counter-match ' GHI / ABC' record. This record must not be returned because there is no Counter-Party correspondent. With this table, the ' ABC / GHI' record should be the one returned in the query.
  
  How can I create a query that will do it?
  
  
  ID | col1 | col2
  --------------------
  1. ABC | DEF
  2. DEF | ABC
  3. ABC | IGS
  4. DEF | IGS
  5. IGS | DEF
  
  
  * Please let me know if you have no idea of what I'm trying to explain.

  I wanted to just the results where col1 = ABC, but I already got the answer I needed on another forum. Thank you anyway.

  SELECT a.col1,
  a.col2
  FROM table_name AS a
  LEFT OUTER
  Table_name JOIN b
  ON b.col1 = a.col2
  AND a.col1 = b.col2
  WHERE b.col1 IS NOT NULL AND a.col1 = 'ABC '.
