• XML PIVOT QUERY QUESTIONS

  I'm new to PIVOT queries.  I was making reference to the discussion that follows, but ran into a problem.  https://forums.Oracle.com/message/9393302

  When I added the XML to format data, I started to have NULL values rather than what I was looking for.

  WITH (AS PIVOT_DATA)

  SELECT * FROM)

  SELECT THE REGION, FCST_PERIOD, PRIME_PART, FINAL_FORECAST

  OF XYZ WHERE FCST_PERIOD > = last_day (trunc (sysdate)) + 1 and FCST_PERIOD < = last_day (add_months(sysdate,12)) AND PRIME_PART IN ('BLAH')

  )

  PIVOT XML (SUM (FINAL_FORECAST) FOR FCST_PERIOD IN (SELECT DISTINCT FCST_PERIOD OF XYZ))

  )

  SELECT PRIME_PART, REGION,

  EXTRACTVALUE(FCST_PERIOD_XML,'/PIVOTSET/ITEM[1]/COLUMN[2]') FCST_PERIOD1,

  EXTRACTVALUE(FCST_PERIOD_XML,'/PIVOTSET/ITEM[2]/COLUMN[2]') FCST_PERIOD2,

  EXTRACTVALUE(FCST_PERIOD_XML,'/PIVOTSET/ITEM[3]/COLUMN[2]') FCST_PERIOD3

  OF PIVOT_DATA;

  RESULTS IN:

  PRIME_PART	REGION	FCST_PERIOD1	FCST_PERIOD2	FCST_PERIOD3
  BLA	MIDWEST	(NULL)	(NULL)	(NULL)
  BLA	WEST-NV	(NULL)	(NULL)	(NULL)
  BLA	SOUTH-EAST	(NULL)	(NULL)	(NULL)
  BLA	WEST-CA	(NULL)	(NULL)	(NULL)
  BLA	SOUTHWEST	(NULL)	(NULL)	(NULL)
  BLA	EAST	(NULL)	(NULL)	(NULL)

  The second part of my question is how would I do a group when you use a pivot query.  When I finished, I've has several parts and would like to group by REGION.

  Thank you!

  Names of elements and attributes in XML are case-sensitive.

  Try with:

  EXTRACTVALUE (FCST_PERIOD_XML, ' / PivotSet/item [1] /column [2]') FCST_PERIOD1

  There is also a good chance that EXTRACTVALUE is frowned upon in your version. Instead, use XMLQuery or XMLTable.

  That being said, using XML PIVOT just to grind it later into a number known columns is pretty useless.

  The same can be achieved much more efficiently with regular PIVOT operator (and if necessary analytical function).

  Post some examples of data in the table of your database and your final result expected to get useful assistance.

• Progressive, Question on the fields of dynamic/DocID/Query Question of profiling

  This may seem like a newb question but someone has a logical division of the BOM designation DocID?

  In the course, we are responsible to use DocID = 1 and DocID = 2, but when/why would you use DocID = 3 or higher?

  Any help would be greatly appreciated with the portion of dynamic fields/query string of the progressive profiling course.

  Thank you.

  The DocID is a complete example. You can actually assign the query string to be what you want. I recently use cmpID for the campaign ID, where I spent to map identity of the campaign and then sent the URL to redirect dynamically the campaign ID field. In my case, we worked with 10 different docs or goods, so we had to actually 10 unique codes. In this case we would have, for example cmpID = 483h76d; cmpID = 9j872hd, etc, etc. If you want to learn more about how you can use the query string values, see this post: how Progressive E10 profiling using the component of cloud - scroll down to step 6 and you'll see how to set up dynamic rules using query strings.

• Query does not work on my iPad (was: media query question)

  I am a site for mobile/tablet/Office of coding and while my office and the iphone respond to the CSS, my ipad does not work. The changes that I do take the tablet in dreamweaver, but when they go live the ipad does not. Of course, my media query must be incorrect, but I can't understand the question. Any help is very appreciated.

  Thank you.

  Yes.  It is inevitable because smart phones are getting bigger while tablets are smaller & more.  He's always going to be some crossover.   Think of it this way, when a Tablet is behaving as a mobile device, he takes over the mobile network.  When the shelf behaves more like a desktop computer, you need the layout of office.

  Similarly, a great smartphone in landscape mode is likely to resemble the layout of your tablet.

  See the FluidGrid example below:

  http://ALT-Web.com/FluidGrid/Fluid2.html

  Office = 4-col layout

  Tablet = 2-col layout

  Mobile = 1-col layout

  For purposes of illustration, I added a thick border of gold at the disposal of the Tablet only.

  / * Tablet Layout: 481px to 768px. Inherits the styles of: Mobile layout. */

  @media only screen and (min-width: 481px) and (max-width: 768px) {}

  .gridContainer {width: 92%; border: 16px solid gold}

• BI Publisher data model / query question

  Hello
  
  I'm designing a report of BI Publisher where I need to show negative numbers in red. I'm perfectly fine with the help of the conditional formatting to do this (just using the default value is conditional formatting in the add-in in MS Word, that generates code like this:)
  
  <? If: number(Cost_-_MTD) < 0? > <? attribute@InContext:color;' Red '? > <? end if? >
  
  BUT...
  
  I have columns returning who sometimes have a NULL value in them, and when they have the value NULL, it causes the foregoing to the pipe upwards. So I thought, 'I'll just add IfNull() in queries defined in the model data, and who will take care of the problem... "
  
  that works - a little. Now, my problem is if I have to go back and change the query for some reason, I get an error "query cannot be parsed, please modify the query manually. I really don't want to do that, I wish that other developers do NOT have to manually change the queries.
  
  So my question is - is it possible to add in the IfNull() directly in the query designer, so it should not be changed manually from that moment?
  
  p.s. using IfNull OBIEE server as our data source.
  
  Thanks in advance,
  Scott

  I don't think there is a way to add the ifnull condition in the query designer. So, you will need to manually change the query...

  In your model so you can add additional control like this:
  <0?>...

  Thank you!

• SQL Query Question campaign

  I have a table that has at least 40 values that I need to use as variables in CCA. My question is. If I write the query as follows:
  
  SELECT AS $Var1 of the value1, value2 AS $Var2, ETC... I do for 40 fields. Would it work if I just do a query where I
  
  SELECT * FROM DBNAME WHERE CALLER = "$ANI."
  
  and then simply use the column as variables names?

  If you need 40 variables in your campaign to act on and use in logic, then you must list and assign all 40 as your first example.

• SQL query question, how to improve it?

  Hello everyone, I want to create a query with result in the following output. Each first-person Department starts with the letter A and goes to the top like this:
  
  Name Department
  A Person1 3
  B Person2 3
  C channels3 3
  D Individu4 3
  Person10 E 3
  
  A 10 Person6
  Person7 10 B
  Person8 C 10
  
  An Individu4 13
  B Person9 13
  
  
  It must be a SQL query, unfortunately no PL/SQL
  
  I was able to create this query, but its lack. Department_id will be a variable, a person can choose a Department or several departments, so the request varies in size.
  
  Select department_id, chr (64 + rownum)
  from (select name, department_id
  employees
  where department_id = 3
  order of id_but, naam

  The employees table has the following columns:
  ID, name, department_id
  
  Can someone help me with this query? Perhaps with the With clause?

  Hello

  You can use the analytic ROW_NUMBER function instead of ROWNUM. Like all analytical functions, ROW_NUMBER can do a calculation separated for each unique value in the PARTITION BY clause:

  select        chr ( 64
             + ROW_NUMBER () OVER ( PARTITION BY  department_id
                           ORDER BY        id_but
                           ,             naam
                         )
             )     AS r_num
  ,        name
  ,       department_id
  from       employees
  where       department_id     IN (3, 10, 13)
  order by  id_but
  ,       naam
  ;
  

  If you do this in SQL * Plus, you can save for the departemnts user input (if it is a list separated by commas as ' 3, 10, 13', or a single value as "99") in a substitution variable (let's call it deptartment_id_list) and use the following WHERE clause:

  where       department_id     IN (&department_id_list)
  

• PTC connector query questions

  I develop a connector and had some questions about the presentation of the petition. I tried to read the documentation and help, but saw no reference to these issues. I know that some of these things may not still have public API, but any help would be appreciated.
  
  (1) is it possible to disable the entry blank for a ComboBox and set one of the values? I am referring to when you click on the button '+' on a query and selecting a comboBox field. I tried the 'enableEmptyEntry' attribute but could do not seem to work.
  
  (2) is there a way to prevent several lines for the same domain? I'm trying to match a web interface that allows values separated by commas in certain areas and not others. Trying to decipher the intent of the user if they use multiple lines for the same field becomes confused.
  
  (3) is there a way to disable 'Match All' or 'match any '?
  
  Thank you

  After further review, the removal of the empty the box entry drop-down list on the query page is not possible.

  One feature that we've added in the last release to support the case where the user needs to find records with a null or empty value for this combobox field. For example, finding bugs without test status. We have generic for all drop-down list boxes.

  The 'enableEmptyEntry' attribute is intended to work with the attribute "emptyEntryValue" as a pair. The user can do something like this in def.xml:
  enableEmptyEntry = 'true '.
  "emptyEntryValue =""
  Our framework poster in the drop-down list instead of empty or the default value .

  We recorded a feature request for this for a future version. Currently, writer connector is not a way to customize our application page, including the MatchAll, MatchAny option.

• where query question

  Ive HI you try to run a query that uses an apex link var to add a where clause per month on a date field

  Select print_month, to_char (PRINT_MONTH, 'Month') of print_schedule

  This query returns

  "PRINT_MONTH", "M".

  ' 01/12/2015', 'December '.

  ' 01/12/2015', 'December '.

  ' 01/10/2015', 'October '.

  ' 01/10/2015', 'October '.

  ' 01/08/2015', 'August '.

  Now then I try this query

  Select print_month, to_char (trunc (PRINT_MONTH), 'Month') of print_schedule where to_char (trunc (PRINT_MONTH), 'Month') = 'December '.

  I have some found data.

  The print_month field is a date column.

  Oracle 12 c

  HI, I fixed that I noticed when I opened the csv file in a text editor so that I could paste the result in the post that there are spaces at the end of month names string, so I added in the trunk as I thought that would fix it, but it didn't so I added now in a PLATE and it works

  Select print_month, RTRIM (to_char (trunc (PRINT_MONTH), 'Month')) from print_schedule where RTRIM (to_char (trunc (PRINT_MONTH), 'Month')) = "December".

  So I have some might explain why this is the case, why should I cut the tank a date version?

  Measure out why add white space on the end?

• SQL Query Question of multiple criteria

  Select emp_id, mgr_id, RESP

  of mydata

  When resp = 'Y '.

  and rownum < = 1

  Connect prior mgr_id = emp_id

  Start by emp_id = 4;

  EMP_ID

  What query is the fastest to get all employees to a certain level of responsibility?

  So, you want to quit looking more far down the tree when you come to a node with an RESP = 'Y', right?

  Just include an RESP = ' don't (or resp. <> 'Y' or NVL (RESP, 'Y' <> 'Y') in the CONNECT BY State, like this:)

  Select emp_id, mgr_id, RESP

  of mydata

  connect mgr_id = emp_id prior

  and RESP = "n"-* NEW *.

  Start by emp_id = 1;

• pivot query question

  I have a query in Oracle 11:
  

   select to_char(da,'DY-DD') days
  from (
          select rownum -1 + to_date('2012-10-15','yyyy-mm-dd') da, l
          from   (select level l
                  from   dual  connect by level <= to_date('2012-10-21','yyyy-mm-dd') - to_date('2012-10-15','yyyy-mm-dd')+1)
          order by 1) 

  Result

  "DAYS"
  MON-15
  TUE-16
  WED-17
  THU-18
  FRI-19
  SAT-20
  SUN-21

  What I need which is present in a row instead of a column:

   MON-15  TUE-16  WED-17  THU-18  FRI-19  SAT-20  SUN-21

  This should be done with pivot requests? Any suggestion please!
  Thanks in advance.

  I need in 7 different columns.
  Oracle version is 11.2.0.1.0. Could you give an example of how to do this with pivot query?

  Here's one way:

  WITH     all_days     AS
  (
       SELECT     LEVEL  AS n
       ,     TO_CHAR ( TO_DATE ('2012-10-15','yyyy-mm-dd') + LEVEL - 1
                 , 'DY-DD'
                 )     AS dy_dd
       FROM    dual
       CONNECT BY  LEVEL <= TO_DATE ('2012-10-21','yyyy-mm-dd') + 1
                          - TO_DATE ('2012-10-15','yyyy-mm-dd')
  )
  SELECT     *
  FROM     all_days
  PIVOT     ( MIN (dy_dd)
         FOR  n  IN (  1  AS col_1
                        ,  2  AS col_2
                        ,  3  AS col_3
                        ,  4  AS col_4
                        ,  5  AS col_5
                        ,  6  AS col_6
                        ,  7  AS col_7
                        ,  8  AS col_8
                        ,  9  AS col_9
                        , 10  AS col_10
                 )
        )
  ;
  

  This always displays exactly 10 columns.
  If the subquery produces less than 10 dates, then the last columns will be NULL.
  If the subquery produces more than 10 dates, will be not shown the 11th (and later versions).

  There is nothing special about the number 10; You can have any number of columns you want. The number of columns and their names is fixed when you write the query, regardless of what is in the subquery. If you want a dynamic number of columns, or names derived from data, see {message identifier: = 3527823}
