• number of distinct values against a few distinct values

  Hello
  If I have a table with millions of records and I query this table with a where clause on a column with few unique values, it would execute faster than this column with many, many distinct values? If Yes, could someone please help me understand why? Where clause would simply like this:
  
  where column1 = 'xyz '.
  
  Could you please answer for cases where the column IS and is not indexed?
  
  Thank you!

  It is the opposite; the query can be faster if you have more distinct values.

  If Yes, could someone please help me understand why? Where clause would simply like this:

  where column1 = 'xyz '.

  Could you please answer for cases where the column IS and is not indexed?

  Oracle will tend to use the indexes that are selective, meaning that there are many distinct values, and thus only a smaller percentage of the table than a given value.
  Imagine you are in a library, and you are looking for an author of some books.
  One way to do that is to look for the author of the catalogue, print a list of all books by this author and search for each of them. This is similar to using an index on a table.
  Another way is to go through the rays, look at each book and see if there is the author of right. This corresponds to a full table scan.
  If 5 authors wrote all the books in this librrary, while about 20% of the books in this library are by a given author, then the 2nd way might actually be faster; looking at each book can be faster than the search for many books, including, more you save the work of assistance from the catalog and store the results of catalog.

  If the column is not indexed, it make much difference how many distinct values are in colum1.

• Drop Dynamics: distinct values

  Hello everyone. Newb here.

  I just started to work on a dynamic web page in Dreamweaver CS3. I use WAMP (MySQL/PHP). I have my web page set up, plugged in and everything works fine.

  I just created a drop-down menu to display the dynamic value (State) of my recordset. My table related to this recordset has a bunch of files with one of the fields in the State. There are several records of each State. When I saw the page in the browser, the menu displays the State of my table, but it displays each status several times (no doubt the number of records that come from that State). Here's the question:

  How can I get this drop-down menu to display the distinct values for the State field?

  i.e. show LA, MS, TX, GA instead of, THE, THE, THE, LA, MS, MS, MS, MS, TX, TX, GA, GA, GA

  Any help would be greatly appreciated.

  Hello kmcamara86

  Yes you place the Select Distinct in the wrong place. The "Select".

  Separate must be in the recordset for the drop, not the drop-down list.

  Open the recordset in the data tab, and then click Advanced to

  the Recordset. Change the sql statement for

  "SELECT DISTINCT (state) FROM table_name";

  If you can email me the code for your page, I can change the

  record set for you.

  Thank you

• 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.

• How to make an application for shaped on the list of dashboard values

  I have the dashboard with several pages that use a set of guests for a year and a month. For some reports, I use the value invited to display data only for this month, but some reports that I need to view the data in the previous 12 months, so I have set these guest not directly for the column, but with the formula as advised by Vincent in his post on the dashboard incentive (http://oraclebizint.wordpress.com/2008/02/26/oracle-bi-ee-101332-between-prompts-for-date-columns-using-presentation-variables/)
  
  The formula I use is "CASE WHEN 1 = 0 THEN ' Sun - Times '.» «Year"ELSE 2007 END", the drop-down list is displayed by SQL statement "SELECT DISTINCT" dim - periods ".» Benefit year "loss analysis" ORDER BY ' Sun - Times '. Year '.
  
  The problem is that, regardless of the setting in the form by default of column "Sun - times» Year', the values are shown with two decimal places, for example "2008,00" at the time.
  The question is - how can I get rid of the decimal places in the list of dashboard values?

  Add CAST as follows... (You need on the "show > SQL result" is part of the dash line, not to change the formula)

  SELECT DISTINCT CAST (' Sun - Times '.) Year AS INTEGER) of 'Profit loss analysis' ORDER BY ' Sun - times» Year '.

• Dynamic list of unique values

  I	II
  A	A
  A	B
  B	C
  B
  C
  C

  I wish I had a way to calculate the values in the column II of the values in the column I. I has many duplicates, and two column he only unique values. What is the best way to achieve this?

  Here's a method:

  

  Column B, the column in the Index, can be hidden.

  Formulas:

  in B2 and filled until the end of the column B:

  IF (COUNTIF(A$2:A2,A2) = 1, MAX(B$1:B1) + 1"," ")

  It counts the number of times the value of 'this line' column that has occurred in cells A2 to 'this line '. If the number is 1, the formula returns an index number one greater than the largest number already in the column in the index.

  In C2 and filled until the end of the column C:

  IF (LINE (−1) > MAX (B),"", LOOKUP (ROW () −1, B, A) ")

  The first part of this is a switch that prevents the SEARCH part to act if all the distinct values have been retrieved. If thye have not, SEARCH returns the value to the column of the row whose column B contains a number one at least the number of line of 'the line '.

• Show only distinct values in narrative mode

  Hi guys!

  Here again, we are trying to reach an ambitious goal.

  It is possible to show only distinct values in a narrative view? For example, I have a query that retrieves about 100 lines. In these lines, a few different years, it is something like this:

  1-2013, Jhon, 10

  2-2013, Brian, 15

  3-2013, Pete, 20

  ...

  10-2014, Steve. 5

  11-2014, Kevin, 12

  ...

  90-2015, Ray, 24

  91-2015, Michael, 2

  ...

  It is possible a mode display narrative only something like that?

  Years: 2013, 2014, 2015

  If I use the feature number @column, I get as many years the results are retrieved. It is not user friendly.

  Any help will be appreciated.

  Best regards

  Hi all!

  I found my own solution and I want to share with you. Maybe it helps someone in the future.

  I used JavaScript to iterate through each row value. By each line, I'll check if it value is added to the overall picture with unique values. If not added, I add it, otherwise, I do nothing.

  Here is my script (pay attention to each code block, it must be in its proper "narrative class"):

• 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

  Just go with PSV.

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

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

  Hello

  The specs say the order is "dependent application": fn: distinct values

  Summary so is (I guess), strict language point of view, should not rest on any apparent order in the resulting sequence.

  The results collected by the two queries probably be different for the same reason: different implementation.

  First one with XQuery Rewrite active is solved using the SQL operators and functions, something along these lines:

  SELECT 'CODEPOINT2STR_FUNC' ('SEQUENCE')

  DE)

  SELECT 'AGGREGATE_FUNC' (VALUE (T) SEPARATE) "SEQUENCES".

  TABLE ("SEQUENCE_FUNC"(99, 98, 97)) T

  ) ;

  While the second is evaluated by the XVM and apparently maintains the original order.

• Return distinct values in a fuction

  Hi all

  I create a function, where it must take two parameters of the input string and return the distinct values of the two channels

  input parameters are: 2.71A2, 2.71X15, 2.71x15 and 2.71A2, 2.71X15, 2.71a2

  I get the output as 2.71A2 parameters, 2.71X15

  need to convert lower case to upper case and compare.

  post needed more information.

  Thank you.

  One way is:

  Select listagg (ds, ",") the Group (control 1)

  from (select distinct superior (REGEXP_SUBSTR (s, "[^,] +', 1, rownum")) ds)

  from (select '2.71A2, 2.71X15, 2.71x15, 2.71A2, 2.71X15, 2.71a2's)

  the double)

  connect by INSTR (s, ',', 1, level - 1) > 0

  and prior sys_guid() is not null)

• XSL transformation - distinct values

  Hello
  
  I have a XML code that is needed using XSL, I think that this can be done using distinct values, however, I have no luck in getting this work. Could someone guide me on what function use. Any guidance / help is greatly appreciated.
  
  Here is the XML source, this scenario is that there are two different products, delivered in a box

  <p:Items>
      <p:Item ItemID="12">
        <p:ProductID>123456</p:ProductID>
        <p:Quantity>1</p:Quantity>
        <p:NetPrice>12</p:NetPrice>     
        <p:Packages>
          *<p:Package BoxID="1">*
            <p:Quantity>1</p:Quantity>
            *<p:TrackingNumber>12345678910111213</p:TrackingNumber>*
          </p:Package>
        </p:Packages>
      </p:Item>
       <p:Item ItemID="12">
        <p:ProductID>1400</p:ProductID>
        <p:Quantity>1</p:Quantity>      
        <p:NetPrice>10</p:NetPrice>      
        <p:Packages>
          *<p:Package BoxID="1">*
            <p:Quantity>1</p:Quantity>
            *<p:TrackingNumber>12345678910111213</p:TrackingNumber>*
          </p:Package>
        </p:Packages>
      </p:Item>     
   </p:Items>

  The XML has to be converted to,
  

   <ns2:package_Data>
              *<tns:package_id>1</tns:package_id>*
              <tns:package_Items>
                 <tns:vendor_item_number>123456</tns:vendor_item_number>
                 <tns:quantity_shipped>1</tns:quantity_shipped>
              </tns:package_Items>
                 <tns:package_Items>
                 <tns:vendor_item_number>1400</tns:vendor_item_number>
                 <tns:quantity_shipped>1</tns:quantity_shipped>
              </tns:package_Items>
              *<tns:trackingNumber>12345678910111213</tns:trackingNumber>*
  </ns2:package_Data>

  If two different products is shipped in 2 different boxes, which will have two box ID and Tracking # the source XML would look like this.
  

  <p:Items>
      <p:Item ItemID="12">
        <p:ProductID>123456</p:ProductID>
        <p:Quantity>1</p:Quantity>
        <p:NetPrice>12</p:NetPrice>     
        <p:Packages>
          *<p:Package BoxID="1">*
            <p:Quantity>1</p:Quantity>
            <p:TrackingNumber>12345678910111214</p:TrackingNumber>
          </p:Package>
        </p:Packages>
      </p:Item>
       <p:Item ItemID="12">
        <p:ProductID>1400</p:ProductID>
        <p:Quantity>1</p:Quantity>      
        <p:NetPrice>10</p:NetPrice>      
        <p:Packages>
          *<p:Package BoxID="2">*
            <p:Quantity>1</p:Quantity>
            <p:TrackingNumber>12345678910111215</p:TrackingNumber>
          </p:Package>
        </p:Packages>
      </p:Item>     
   </p:Items>

  The transformed XML should look like this,
  

   <ns2:package_Data>
              *<tns:package_id>1</tns:package_id>*
              <tns:package_Items>
                 <tns:vendor_item_number>123456</tns:vendor_item_number>
                 <tns:quantity_shipped>1</tns:quantity_shipped>
              </tns:package_Items>
              *<tns:trackingNumber>12345678910111214</tns:trackingNumber>*
  </ns2:package_Data>
  <ns2:package_Data>
              *<tns:package_id>2</tns:package_id>*
              <tns:package_Items>
                 <tns:vendor_item_number>1400</tns:vendor_item_number>
                 <tns:quantity_shipped>1</tns:quantity_shipped>
              </tns:package_Items>
              *<tns:trackingNumber>12345678910111215</tns:trackingNumber>*
  </ns2:package_Data>

  Here is the XSL code, I tried to use different values in the for-each leading to the error, the code below works fine for the second scenario mentioned above.
  

   <xsl:for-each select="/ns0:OrderStatus/ns0:Items/ns0:Item/ns0:Packages/ns0:Package">
              <ns2:package_Data>
                <tns:package_id>
                  <xsl:value-of select="@BoxID"/>
                </tns:package_id>
                <tns:package_Items>
                  <tns:vendor_item_number>
                    <xsl:value-of select="../../ns0:ProductID"/>
                  </tns:vendor_item_number>
                  <tns:quantity_shipped>
                    <xsl:value-of select="../../ns0:Quantity"/>
                  </tns:quantity_shipped>
                </tns:package_Items>
                <tns:trackingNumber>
                  <xsl:value-of select="ns0:TrackingNumber"/>
                </tns:trackingNumber>

• Select the records from the first n distinct values of column

  I need to write a query in plsql to select records for the first 3 values distinct from a single column (example below, ID) and all lines for the next 3 distinct values of column and so on until the end of the number of distinct values in a column.

  How to write a query for this inside a loop.

  Hello

  Thus, a panel will consist of the lowest id value, the 2nd lowest and the 3rd lower, reggardless of how many lines is involved. The next group will include the 4th lowest id, the 5th lowest and the 6th lowest. To do that, you must assign the numbers 1, 2, 3, 4, 5, 6,... for the rows in order by id, with all lines with the same id, getting the same number and without jumping all the numbers.
  This sounds like a job for the analytical DENSE_RANK function:

  WITH     got_grp_id     AS
  (
       SELECT     id, name, age
       ,     CEIL ( DENSE_RANK () OVER (ORDER BY id)
                 / 3
                 )          AS grp_id
       FROM     table_x
  )
  SELECT     id, name, age
  FROM     got_grp_id
  WHERE     id     = 1     -- or whatever number you want
  ;
  

  If you would care to post CREATE TABLE and INSERT statements for your sample data, then I could test it.

• XSL - distinct values

  Hi Vlad,
  
  I have a problem with the xsl transformation, if a value in the input xml file is same in same/orders multiple, unique values gets added in the same node, in the example below, I have a SKU order '2' with Qty '1' and SKU '4' with '2' quantity, so my csv file will come with 3 lines, 1 line for the lines of CODE '2' and 2 for SKU4. The output seems to add the two distinct values (such as < ns0:quantity_ordered > * 1 2 * < / ns0:quantity_ordered >) in the same node, as shown in the example below. I don't know if I'm a bad button in the Item_Data or something else,
  
  I believe, I do not use good condition to check the separate SKU or by using a condition for each stay, I don't know if that's the problem. I would be grateful if you could tell me the problem.
  
  Thank you
  VINET

  Don't know if is that the first node is 0 or 1 (there is a difference between the implementations)... There the previous does not work, try to replace [0] [1]...

  See you soon,.

• Select the distinct value of a column in the collection in bulk.

  Hi all
  
  Collecting the data of a query to a variable of type table. I need to select a separate of a perticular column value in the collection.
  
  Collection has followiing values inside.
  

  Col(c).articleid,
  Col(c).userkey,
  Col(c).origin,
  Col(c).addnlorigindata,
  Col(c).avdest,
  Col(c).dispfmt,
  Col(c).sourcecode,
  Col(c).success_ind,
  Col(c).error_code,
  Col(c).entry_createddate,
  Col(c).createdby,
  Col(c).filenumber,
  Col(c).linenumber,
  Col(c).acctnum,
  Col(c).assetkey,
  Col(c).autocompletedterm,
  Col(c).accessionnumber,
  Col(c).requestdatetime,
  Col(c).requestorip,
  Col(c).articleordinal,
  Col(c).userinitiatedind,
  Col(c).captchastatus

  I need to select distinct column values (for example: Col (c) .sourcecode) collection and the need to insert in the table if the value in this column does not exist in the table.
  
  Say, Col (c) .sourcecode has the value XYZ, ABC. If the "XYZ" value does not exist in the table, so I need to insert in the table and if "ABC" exists in the tables then don't insert it. (something like fusion) after seecting to the distinct values in a column in the collection.
  
  Thanks n regards
  Nana Akkivalli.

  The collection must be inserted before you can use this topic.

  In the Begin block, you have to collect a loose and insert inside: something like

  SELECT *
  BULK COLLECT INTO l_array
  FROM ALL_USER
  ...CONDITIONS...
