  I have a column with two values, separated by a space, in each line. How do I create 2 new columns with the first value in one column and the second value in another column?

  Add two new columns after than the original with space separated values column.

  

  Select cell B1 and type (or copy and paste it here) the formula:

  = IF (Len (a1) > 0, LEFT (A1, FIND ("", A1) −1), ' ')

  shortcut for this is:

  B1 = if (Len (a1) > 0, LEFT (A1, FIND ("", A1) −1), ' ')

  C1 = if (Len (a1) > 0, Member SUBSTITUTE (A1, B1 & "", ""), "")

  or

  the formula of the C1 could also be:

  = IF (Len (a1) > 0, RIGHT (A1, LEN (A1) −FIND ("", A1)), "")

  Select cells B1 and C1, copy

  Select cells B1 at the end of the C column, paste

• OPV with distinct values for the guests

  Hi all

  Could you get it someone please let me know where/what I'm wrong. I created the couple of OPV to get distinct values, as I can't use the view that has millions of data to load guests.

  These OPV is not directly attached to my main table but joined someother tables; After you add the guests in the responses, is to show the below error

  [nQSError: 14070] can't find coverage source logical table to the columns of the logic: [bp Manager]. Please check more detailed level keys are correctly mapped. (HY000)

  I wan to the OPV use only for guests and pass the values to help requested on the main table filters

  I have no warnings/errors in my model. What could be the problem? Thank you for your time

  REDA

  Just go with PSV.

  Check it cool - bi.com for "what happens when we select all the column values.

  Table x got to join the only 1OPV then how can you expect comes from BI to the other 2 open-pollinated varieties? Likewise, we cannot write query!

  If you can create a domain for each OPV then proceed with a command prompt with the UNION of 3 open-pollinated varieties clause

• update of NULL in the column with the values of the adjacent column

  Examples of data

  with test_data as
  (select 1 as one, null as two, 2 as three,5 as four, 6 as five, null as six from dual
  union all
  select 1 as one, null as two, 2 as three,5 as four, 6 as five, null as six from dual)
  select * from test_data;
  

  This is one of those cases, the case may be where any value of a column can be null

  or two similar columns can be null. If the column is null then I want to update the adjacent column

  average value of the column, if the first column is null so I want to take the next non-null column and update, if the last column is null

  so I want to take prev not zero column and to update.

  In this case would be my expected output

  1	1.5	2	5	6	6
  1	2	3	5	6	6

• Adding a UNIQUE CONSTRAINT to an existing column with duplicate values

  Oracle Forums Hello, I have a table that contains rows 11 901. I tried to define the UNIQUE constraint on the column of xcode, but encountered an error: the column already contain duplicates! I rescued following SQL 'SELECT COUNT (*) FROM States;' the result is 11 901 and 'SELECT COUNT (DISTINCT (xcode)) FROM States;' the result is 11 680. So to enforce this unique key I have to remove the 221 lines. Please how can I do this?

  REMOVE duplicates...

  For example, as

  delete from your_table t
  where rowid <
     (
     select max(rowid)
     from your_table r
     where t.unique_column = r.unique_column);
  

  Thne create the constraint.

• How to update columns with the value of other lines in the same table

  Hello
  
  I use Oracle 11.2, I'd use SQL statements to update a column based on values in other rows in the same table. Here are the details:
  
  create table TB_test (number 4 myId, crtTs date, date of MDPU);
  
  insert into tb_test (1, to_date ('20110101', 'YYYYMMDD'), null);
  insert into tb_test (1, to_date ('20110201', 'YYYYMMDD'), null);
  insert into tb_test (1, to_date ('20110301', 'YYYYMMDD'), null);
  insert into tb_test (2, to_date ('20110901', 'YYYYMMDD'), null);
  insert into tb_test (2, to_date ('20110902', 'YYYYMMDD'), null);
  
  After you run the SQL code, I would like to have the following result:
  
  1, 20110101, 20110201
  1, 20110201, 20110301
  1, 20110301, null
  2, 20110901, 20110902
  2, 20110902, null
  
  Thanks for your suggestion.

  I guess you need this, otherwise please explain logic correctly:

• Populating a drop-down menu form with the values from MySQL database

  I'm creating a simple CMS that will allow staff to add new items on their site (sale of furniture).

  I want them to be able to choose from the list of values for some fields to ensure that the items are displayed on the website correctly (IE to avoid typos etc.).

  I have spent a lot of time to trawl forums and have so far obtained the code below.  When it was working I could only get the dropdown menu options of data contained in the database, as opposed to the list of DEFINED values that initially, I would put in my database.

  For example under the field named 'Type', I assigned these values: all ('table', 'chair', 'buffet', 'convenient', 'bottles', 'library', 'mirror', 'drawers','s chest', 'display', 'tvunit', "bedside", reads, "wardrobe", 'dressingtab', 'blanketbox', 'Office', 'filing cab', "workstation")

  Here's what I want to display in the drop-down, not only the five values of elements already in it.

  However, my CMS page is nothing display now not in the drop down and I can't understand why not!

  So my question is, first of all any ideas what's wrong with my code?  And second, how to fill the bottom of the fall with SET values?

  Thank you very much in advance for your help!

  I didn't want to bore you, then the code below is just the bit that is relevant to my question, rather than any connection $POST and info php etc.

  It is in my code php at the top of my page

   $sql = mysql_query("SELECT DISTINCT id, supplier, room, type, material, finish, bespoke, image FROM furniture ORDER BY ASC");
  
                      while($row = mysql_fetch_assoc($sql))
                      {
                  $supp .= "<option value=\"{$row['supplier']}\">{$row ['supplier']}</option>";
                  $room .= "<option value=\"{$row['room']}\">{$row['room']}</option>";
                  $type .= "<option value=\"{$row['type']}\">{$row['type']}</option>";
                  $material .= "<option value=\"{$row['material']}\">{$row['material']}</option>";
                  $finish .= "<option value=\"{$row['finish']}\">{$row['finish']}</option>";
                  $bespoke .= "<option value=\"{$row['bespoke']}\">{$row['bespoke']}</option>";
                      } 
  

  It's in my html code

  <form action="<?php echo $editFormAction; ?>" method="POST" enctype="multipart/form-data" name="form1"  id="form1">
  
                  <label for="supplier">Manufacturer</label>
                  <select name="supplier" id="supplier" title="<?php echo $row_add['supplier']; ?>" >
                    <? echo $supp; ?>
                   </select>
         
  
                   <label for="room">Room</label>
                  <select name="room" id="room" title="<?php echo $row_add['room']; ?>" >
                    <? echo $room; ?>
                   </select>
  
                         <label for="type">Type</label>
                        <select name="type" id="type" title="<?php echo $row_add['type']; ?>">
                         <? echo $type; ?>
                        </select>
     
  
                        <label for="material">Material</label>
                        <select name="material" id="material" title="<?php echo $row_add['material']; ?>">
                        <? echo $material; ?>
                            </select>
         
                            <label for="finish">Finish</label>
                        <select name="finish" id="finish" title="<?php echo $row_add['finish']; ?>">
                          <? echo $finish; ?>

                        <input type="hidden" name="MM_insert" value="form1" />
                        </form>
  

  > So, don't you think not with my different approach?

  Yep, that's how it should be done.

  Note the OP also mentioned that they are filled with 6 drop-down lists:

  > 6 fields I want to post, drop downs in my a form are: provider, room, type of material, finish and custom.

  So you can create a table for each separate... but what I would probably do is store everything in a single table (depends of if you need to store additional information or if it's just a list of choice):

  optionsTbl

  Category ID value

  ------------------------------

  1 provider abc

  2 vendor xyz

  3 living room

  4 dining

  Enter values using a set of multiple records in the query: Select value of optionsTbl category WHERE = 'suppplier. " Select the value optionsTbl category = "room"; etc.

  Then fill the drop-down lists by looping through each query in the recordset and use next_result() to perform a loop on the next game.

• How to build a collection ArrayCollection with distinct values of an XMLListCollection?

  Hello, I'm really bad with what seems like it should be a very simple task. I have a XML of course object which consists of only the names of course. I just want to create a new collection of ArrayCollection which consists of only the names of DISTINCT/UNIQUE course in the XML list to use in a combobox control. I tried all sorts of things but nothing I try seems to work. I have a few listed below MXML.
  
  Any help would be appreciated! Should be simple im sure, and once I understood that, it will make my app built much easier! The value of myDistinctData is the final ArrayCollection collection. For simplicity, I left my attempts failed the loop foreach. THANKS TO ANYONE WHO CAN OFFER HELP!

  I don't know how to remove duplicates in an ArrayCollection collection or otherwise.
  But since you already have an XML and require only a text node inside.
  I go through the easiest way.

  Course 1
  
  
  Course 2
  
  
  Course 3

  Course 3
  
  ;

  you need to do collection here ArrayCollection instance before put something u.
  this.myDataDistinct = new ArrayCollection();

  E4X selection
  var xmlList:XMLList = myData.course.name;

  for each (var xml in xmlList)
  {
  trace (XML); you will see that we have now.

• Return only the columns with different values.

  Hi all
  
  I am trying to solve a seemingly trivial problem but can't seem to get any clear answer anywhere in any forum. Consider a single table with 5 columns and only two lines:
  

  row_id           first_name         last_name        age            gender
  1                    John                  doe               27             M
  1                    Jane                  doe               27              F  

  Assume that there is no primary key or any other constraint. Also assume that there are only and only two lines of this table. So I need basically a query that, overall above lines, would return first name and sex, because they are only different columns in two lines, as well as their values. Even if I can get sort of column names that are different and that would be enough that I can easily access the values later. It is also important to remember that I may not know the names of the columns in the columns, so basically, somehow, I use user_tab_columns in the process.
  
  Any help appreciated.

  This assumes that you have really a table, then you can use ROWID to distinguish the lines, since there is no primary key.
  If this isn't the case, you first assign ROW_NUMBER in a subquery.

  It is supposed to look like this:

  *Accounts* 
  
  AcctNum   Prefix   Suffix
  -------   ------   -------
  123-0097    123     0097
  X089-056
  123-0097
  123-0098
  F3377-D
  X089-057
  X089-058
  3-009712

  That's what I came with, but it does not work because it is basically putting multiple values into a single cell:

  update accounts
       set prefix=(select substr(acctnum, 1, instr(acctnum,'-')-1) from accounts),
       suffix=(select substr(acctnum, instr(acctnum, '-')+1) from accounts)
       where acctnum=(select prefix||'-'||suffix from accounts);

  I want this query is incredibly easy and I have forget something. Any help is greatly appreciated.

  UPDATE accounts a
  SET    ( prefix, suffix ) = (SELECT Substr(acctnum, 1, Instr(acctnum, '-') - 1),
                                      Substr(acctnum, Instr(acctnum, '-') + 1)
                               FROM   accounts b
                               WHERE  a.acctnum = b.acctnum);
  

• ORDER BY a column with NULL values only

  Hello
  
  The order of column has all null values for the results of my query set.
  
  Ex:
  
  Select a, b, c from table1 where type = 'type1' and ID = "id1" order by column1
  
  In the above query, "column1" contains nulls for 'type1 '. The order of the records in the result set is different for different ID values if the values of a, b and c are always the same.
  What is happening in the 10g database.
  
  I have also observed that the order of the records for the same query conforms in the 9i database.
  
  (1) is the difference due to the difference in versions of database?
  (2) is there a way to get the order even records independently entry ID?
  (3) I cannot in the same order in 10 g DB too as the order in 9i DB?
  
  Thank you.

  If two or more rows have the same values (or NULL) for each ORDER BY expressions, then you may not be sure what order they will be. The system is free to do whatever he finds convenient. What the system identifies Dresser can vary depending on many factors, including the version, the size of the table, the conditions in the WHERE clause, there is a GROUP BY clause, or not... In all cases, it is not something that you can depend on. If you want the output in a certain order, to specify the order in the ORDER BY clause.

  (1) is the difference due to the difference in versions of database?

  Could be. In all versions, Oracle said that you cannot count on the order being compatible, except if the ORDER BY clause, it is consistent.

  (2) is there a way to get the order even records independently entry ID?

  Add more expressions at the end of the ORDER BY clause, as tie-breakers.
  For example:

  ORDER BY  column1
  ,         a
  ,         b
  ,         c
  

  If table1 is really a table (not a view), you can add a ROWID.
  In most cases, you can ORDER BY expressions that are not in the SELECT clause. So if you have a primary key, you can usually ORDER BY it, even if you don't see it.

  (3) I cannot in the same order in 10 g DB too as the order in 9i DB?

  Of course, ORDER BY works the same in all versions. If you have an ORDER BY clause to unambiguously, the output will be exactly the same order in any version.
  Remember that the absence of ORDER BY has no effect in all versions. If you have an ORDER BY of ambiguous clause, you can not count on the coming out in a particular order in any version.

• Filter a column with the value of another

  Hello. Hope someone can help with this... On my search page, I want to use the value of the first list/drop-down menu to filter the values of the second list/menu. I use PHP and DW 8.0.2.
  
  Example: The first column has each of the 50 States. second column has 3 000 counties. If a user selects New Jersey, I want to just 21 NJ counties to appear as options in the second menu downwards rather than 3 000 counties.
  
  First Recordset works very well for the States. But in my second recordset, I say 'select distinct County of the said County WHERE AS var1'... and var1 is $recordset1 [County]. But the 2 column is empty. How can I actively pass the value of the first column in the second while the user is still on the same page?

  >>
  Assuming that your table has a field named "State":
  «select County of States WHERE state = "var1""
  >>

  You can use this solution when the first menu page 1 and the second menu on page 2 (IE passing the value of a query on page 2), but as assumingly, you need to have this functionality within a single page, basic need based on a javascript solution 'drop-down menus of dynamic load' to load the menu2 - options "in situs.

  There is an extension for Dreamweaver stand alone for this on the site of Tecnorama , that also wants to work without the relationships between the tables, in other words, with the data in a table, which matches your scenario.

• String column with some formats from date to date

  Hello!
  IM new in Oracle :)
  I need to convert a string column {VARCHAR2 (70 bytes)} to this day. But this column have some type os dates... I found three types:
  
  17/02/12 06:00:04, 403398 - 02:00
  19 MARCH 12 06.00.07.936287 AM - 03:00
  06:00:03:000 30/03/2012
  
  How can I convert this column to date? I have hours, just need the date...
  IM using Oracle 10 g.
  
  Thank you very much!

  The fact is that any analysis fails for a date like 10/11/12.
  You have only one chance if you know for sure that the order of the months of the year and the day is always the same. otherwise you can only guess.

  If guess is good enough depends on the importance of the process of using it for the success of your business...

  Good bye
