• -You also get an invalid identifier error when executing this query sql for a data model, but not in TOAD/SQL Developer?

  Hello OTN.

  I don't understand why my sql query will pass by in the data model of the BI Publisher. I created a new data model, chose the data source and type of Standard SQL = SQL. I tried several databases and all the same error in BI Publisher, but the application works well in TOAD / SQL Developer. So, I think it might be something with my case so I'm tender hand to you to try and let me know if you get the same result as me.

  The query is:

  SELECT to_char (to_date ('15-' |)) TO_CHAR(:P_MONTH) | » -'|| (To_char(:P_YEAR), "YYYY-DD-MONTH") - 90, "YYYYMM") as yrmth FROM DUAL

  
  

  Values of the variable:
  

  : P_MONTH = APRIL

  : P_YEAR = 2015

  I tried multiple variations and not had much luck. Here are the other options I've tried:

  WITH DATES AS

  (

  Select TO_NUMBER (decode (: P_MONTH, 'JANUARY', '01',))

  'FEBRUARY', '02',.

  'MARCH', '03'.

  'APRIL', '04'

  'MAY', '05'.

  'JUNE', '06'.

  'JULY', '07',.

  'AUGUST', '08'.

  'SEPTEMBER', '09'.

  'OCTOBER', '10',.

  'NOVEMBER', '11'.

  "DECEMBER", "12."

  '01')) as mth_nbr

  of the double

  )

  SELECT to_char (to_date ('15-' |)) MTH_NBR | » -'|| (TO_CHAR(:P_YEAR), 'DD-MM-YYYY') - 90, "YYYYMM")

  OF DATES

  SELECT to_char (to_date ('15-' |: P_MONTH |)) » -'|| ((: P_YEAR, 'MONTH-DD-YYYY')-90, "YYYYMM") as yrmth FROM DUAL

  I'm running out of ideas and I don't know why it does not work. If anyone has any suggestions or ideas, please let me know. I always mark answers correct and useful in my thread and I appreciate all your help.

  So I thought to it. It seems that there is a bug/lag between the guest screen that appears when you enter SQL in the data model and parameter values, to at model/value data.

  Here's how I solved my problem.

  I have created a new data model and first created all my settings required in the data model (including the default values without quotes, i.e. APRIL instead "Of APRIL") and then saved.

  Then I stuck my sql query in the data model and when I clicked ok, I entered my string values in the message box with single quotes (i.e. "in APRIL' instead of APRIL)

  After entering the values of string with single quotes in the dialog box, I was able to retrieve the columns in the data model and save.

  In the data tab, is no longer, I had to enter the values in single quotes, but entered values normally instead, and the code worked.

  It seems the box prompted to bind the values of the variables when the SQL text in a data model expects strings to be wrapped in single quotes, but no where else. It's a big headache for me, but I'm glad that I solved it, and I hope this can be of help to other institutions.

  See you soon.

• Can I use data string Web App (image) in a CSS hover function?

  I'm developing a profile of employee of company "show and tell" using the Web application. I built my item in the list and details. Works very well. However, I have no hover function. So, I created a few css - one div id and added a background image then hover div with another image to hover. It worked. I moved the code of Dreamweaver in British Colombia - inside (the list template) Web application. I replaced the paths of the image with the data string Web App - image (e.g. {tag_employee photo}). Then I did the same thing to hover - I changed the image of the data string (e.g. {tag_employee photo2}). It does not work now.

  All CSS is written inside the body, so it's not pulling to the outside path. I thought that a path from the outside may not understand the data string.

  How can I get this to post a link with the chain of image data? Am I missing something?

  How can I create an image using CSS switch and function WITH the BC Web App data strings hover?

  Here's how I wrote the id of the DIV:

  
  

  # {List_photo

  height: 200px;

  Width: 200px;

  background-image: url("{tag_employee photo (200px)}" ");

  position: relative;

  margin-bottom: 10px;

  Display: block;

  }

  # {List_photo:hover

  height: 200px;

  Width: 200px;

  background-image: url("{tag_employee photo (hover)}" ");

  position: relative;

  margin-bottom: 10px;

  Display: block;

  }

• How to get the query of the region "PL/SQL function body returns the query string"?

  Hello
  
  is it possible to get the query string from the region of type "PL/SQL function body returns the query string"?
  
  I can get the definition of the region as a PL/SQL procedure, but I am interested in the returned query. I tried to write something like
  
  < pre > v_return_query: = «...» » ;
  : P49_QUERY: = v_return_query;
  Return v_return_query; < / pre >
  
  to save the return on hidden item P49_QUERY string, but it does not work. I get the error message: ERR-1002 cannot find the item for the "P49_QUERY" element ID in the application '4000 '.

  If you need to make reference to a page element in the block then you can use this type of control to avoid having to use generic column names:

  if apex_application.get_current_flow_sgid(:APP_ID) = apex_application.get_sgid then-- runtime  :P9_SQL := vSQL;else-- design time  null;end if;
  

  But if all you want to do is capture the SQL debugging you can take all the references element in the block and use the insert statement (in a debug table) as I showed earlier.

  Concerning

• PL/SQL functions as LOV to use in another display object

  Hello

  We had a custom search to extract data from a display object and the data displayed as a Table of ADF. Now, there are few requests for searches on this report. Go see criteria and Panel request if we allow saved search. But the fields used in the research are going through a lot of logic and thus the PL/SQL functions are implemented. We used to call these functions and lists separated by commas and then divided the list into individual elements and put in the component "select options".

  The value (String) returned by the pl/sql function is something like - APAC, EMEA, NORTH AMERICA, FDA

  I am creating a LOV based on SQL-query "Select getRegions() from dual;

  Now, I want the list separated by commas to divide so that I could use this LOV in an another view and try the display criteria and saved searches.

  I tried to assign as LOV just to check and the criteria drop-down view for region displays same value as single element - "APAC, EMEA, NORTH AMERICA, LAD."

  I want it to be 4 separate - elements

  APAC

  EMEA

  NORTH AMERICA

  DVL

  Is there anyway to achieve this?

  Or better is at - it another way to do this (maybe I'm wrong)

  Thank you.

  JDev: 11.1.2.4

  Instead of a programmatic VO of PL/SQL, I found sometimes easier to write PL/SQL functions that return a table - need to CREATE a TYPE for the data items to be returned and a TYPE of TABLE IMBRIQUE tabular form of the first kind.  The function returns the type of table, and can even be a PIPElined table function.  Then I create a VO with the following text:

  SELECT * from TABLE (my_function_returning_table)

  The function can even take parameters, which you fill with variable BIND your VO.

• No support for oracle sql functions

  Hi all
  
  Please can someone explain why the B-tree indexes are not capable of supporting SQL queries using the built-in functions of Oracle.
  
  We have indexes of tree b on account_no column.
  
  Select * from test_table where account_no = 11005208
  
  the above query use the index on account_no
  
  Select * from test_table where superior (account_no) = 11005208
  
  But this query does not use the index on the account_no, going for the full table scan.
  
  My question here is account_no is the numeric data type.
  Then, there is no difference between the data in the columns account_no and upper (account_no) column data, so why he does not use index when using sql functions in an sql query?

  Hello

  If you apply the upper function, Oracle implicitly converts its argument to a string, so your query is actually upper (to_char (account_no)).
  There is none HAVE fully functional in the optimizer and you do not expect to know everything and do all the conclusions that a human being can do. Why should Oracle re - write this type of query analysis the data type of the columns and features when it seems more natural programmer write a correct query (without capital letters in this example) or, if necessary, create an index based on a function?

• Problem inserting new line in a VO with SQL functions and subqueries

  Hello
  
  I use JDeveloper 10.1.3.4 and and stuck with insertion of a new line when the values to insert into some fields of the new line are returns of SQL functions and subqueries.
  
  At the sqlplus prompt, the following sql statement is tested and developed successfully:
  

  insert into VALIDATIONS values (
     '111223333', 'JANE', 'DOE',
     SYSDATE,
     (select to_char(sysdate, 'yymmdd') from dual)||
     (select to_char(count(TRANSACTION_DATE)+1,'fm0999') from VALIDATIONS
        where trunc(TRANSACTION_DATE) = to_char(sysdate))
  );

  Note that the values for the fields of 4th and 5th are returns of subqueries and SQL functions.
  
  Ideally, it would be simple to assemble a SQL and executed him as he did to the old way of servlet:
  

  String sql = "insert into VALIDATIONS values ('" + id + "', '" + firstName + "', '" + lastName + "', SYSDATE, (select to_char( ......)))";
  statement.executeUpdate(sql);

  I'm not sure it can be done in JDeveloper, and it was not found in the developer's guide. What I found was rather:
  

  // 1. Find the ServiceRequests view object instance.
  ViewObject svcReqs = am.findViewObject("ServiceRequests");
  // 2. Create a new row and insert it into the row set
  Row newSvcReq = svcReqs.createRow();
  svcReqs.insertRow(newSvcReq);
  // 3. Show effect of entity object defaulting for Status attribute
  System.out.println("Status defaults to: "+newSvcReq.getAttribute("Status"));
  // 4. Set values for some of the required attributes
  newSvcReq.setAttribute("CreatedBy",308); // Nancy Greenberg (user)
  Date now = new Date(new Timestamp(System.currentTimeMillis()));
  newSvcReq.setAttribute("RequestDate",now);
  newSvcReq.setAttribute("ProdId",119); // Ice Maker
  newSvcReq.setAttribute("ProblemDescription","Cubes melt immediately");
  // 5. Commit the transaction
  am.getTransaction().commit();

  In my case, it would be OK for the first three fields as shown below (in the code of transactionsRecords is a display object). But what about the 4th and 5th fields?
  

  Row newTransaction = transactionsRecords.createRow();
  transactionsRecords.insertRow(newTransaction);
  newTransaction.setAttribute("StudentId", id);
  newTransaction.setAttribute("FirstName", firstName);
  newTransaction.setAttribute("LastName", lastName);
  
  newTransaction.setAttribute("TransactionDate", <how to put "SYSDATE" here?>);
  newTransaction.setAttribute("ConfirmNumber", <how to put subqueries here?>);

  A big thank you to those who know or have experience before!
  
  
  Newman

  Newman,
  You can do this via a procedure call. This technique is described here
  I guess you can't do this directly in the EO or VO.
  You can do it the old way to create a prepared directly query and call it as you described. To get the declaration use getDBTransaction () .createPreparedStatement (...) method available in the module of your application.
  Be aware of the implications using the given solution. The framework doesn't know anything of what you are doing. So to see the changes that you used to update the tables that you change.

• PL/SQL function to calculate the non-working days

  Hello

  I have the following pl/sql function which generates a number of days between two selected dates (i.e. excluding weekends). However, I also need to exclude specific holidays - day of Christmas etc. These holiday dates are stored in a table in our database (11 GR 2) called "HOLIDAY".

  How can I integrate the holidays which is held in the table of holidays in the following query to exclude these dates as well? I know how to write a separate funtion pl/sql for a number of days between two dates using SELECT... BUT I can't work out how to bring together them in a single query.

  Could someone show me how with the pl/sql / dates below please?

• Help SQL function

  Hi all

  I have a table which includes

  ID, first_name, last name and date of birth

  I want to retrieve all the records that have the same name and DOB

  for example.

  ID, first_name, last name, DOB

  1 xyz abc 01/01/2012

  hij 2 efg 15/05/2012

  3 xyz abc 01/01/2012

  4 xyz abc 01/01/2012
  

  so in the output of 1, 3 and 4 rows will appear only.

  can someone advise please on the appropriate SQL function

  Thanks in advance

  Hello

  One way is to use the analytical COUNT function:

  WITH got_num_rows AS

  (

  SELECT id, first_name, last_name, dob

  , COUNT (*) OVER (PARTITION BY first name

  last_name

  ,             dob

  ) AS num_rows

  FROM table_x

  )

  SELECT id, first_name, last_name, dob

  OF got_num_rows

  WHERE num_rows > 1

  ;

  The subquery is needed here, because the analytical functions are calculated after the WHERE clause has been applied.  To use the results of an anlytic function in a WHERE clause, you must calculate the function in a subquery, then you can use the results where you want (including the WHERE clause) of a Super query.

  Who today replaces "ora: see?

  On 11.2, ora expansion feature: view() is deprecated in favor of the fn:collection("oradb:/") method:

  http://docs.Oracle.com/CD/E11882_01/AppDev.112/e23094/xdb_xquery.htm#BABECFFD

  My DBA database have installed Oracle XML DB to use the XMLType and XMLTable, I thought that these features among other things speed up the creation of XML.

  What are the benefits of using XQuery and XMLTable and XMLQUERY functions?

  Which version of the database you use?

  Please read: http://docs.oracle.com/cd/E11882_01/appdev.112/e23094/xdb_xquery.htm#CBAGCBGJ

  Is there another method to expedite the creation of XML?

  Publication of SQL/XML functions are probably the best way to create custom relational data XML documents.

  The basic functionality of XQuery is not to the RDBMS query tables or views, although Oracle provides extensions to do.
  Most of the time, I use XQuery (via XMLTable and XMLQuery) to do exactly the opposite, i.e. to extract XML data in a relational form, or the transformation of XML fragments.

  If your actual requests are slow - even if you need to define what that means and that you are pregnant - then maybe the SQL/XML functions are not the real problem.

  In a "Where clause" as I turn, I have several "outer join". Here is an example.

  where
  PPM. NSU_PPM = w.NSU_PPM and FRNS. NSU_FRN (+) IS FCO. NSU_FRN and FCO. NSU_FCO (+) IS PPM. NSU_FCO
  and T2O. NSQ_T2O (+) IS PPM. NSQ_T2O
  and T51. NSQ_T51 (+) IS PPM. NSQ_T51
  and TWU. NSU_STT (+) IS PPM. NSU_STT
  and T01. NSQ_T01 (+) IS PPM. NSQ_T01
  and vpm.cod_rmp_vpm (+) = "PRA".
  and vpm.num_vsn_vpm (+) = PPM.vsn_sup
  and w.nsu_ppm = A.nsu_ppm (+)
  and W.NSU_SOO = A_HEADER. NSU_SOO and A_HEADER. NOR_SOM = 0

  Yes, it's exactly what I was talking about.
  Transposing the logic for XQuery 1.0 is not the approach more simple (to say the least), because there is no direct support OUTER JOIN.
  XQuery 3.0 provides the functionality, but it is not yet here in the database.

  My suggestion would be to stick to the publication of SQL/XML functions.
  If you have a specific question about the performance, we (as the members of the forum) will be happy to help you.

• PL/SQL function for the addition of "days."

  I created a function that, at a date and a number, adds many days to the date. The problem is that there are parameters to include Saturday, Sunday or Monday as these days. Here is an example of the call
  
  DAYSBETWEEN('01-Aug-11',5,0,0,0) will give 5 calendar days since August 1, 2011 (that you would not exclude Saturday, Sunday or Monday)
  
  DAYSBETWEEN (August 1, 11 ', 5, 1,1,0) would give you 5 working days since August 1, 2011
  
  DAYSBETWEEN('01-Aug-11',5,0,1,1) would give you 5 days of August 1, 2011 spring break Sunday and Monday.
  
  My current role is:
  

  create or replace
  FUNCTION DAYSBETWEEN(
        DAYIN  IN DATE ,
        ADDNUM IN NUMBER ,
        EXSAT  IN NUMBER ,
        EXSUN  IN NUMBER ,
        EXMON  IN NUMBER )
      RETURN DATE
    IS
      dtestart DATE;
      intcount NUMBER;
      holidays NUMBER;
    BEGIN
      dtestart       := DAYIN;
      intcount       :=1;
      WHILE intcount <= ADDNUM
      LOOP
        dtestart     := dtestart + 1;
        IF NOT((EXSAT = 1 AND TO_CHAR(dtestart, 'd')= 7) OR (EXSUN=1 AND TO_CHAR(dtestart, 'd')= 1) OR (EXMON=1 AND TO_CHAR(dtestart, 'd')= 2)) THEN
          intcount   := intcount + 1;
        END IF;
      END LOOP;
      RETURN dtestart;
    END DAYSBETWEEN;

  This works for a small set of values for the date, but when there is a bigger set of dates, it takes hours to complete because of the time loop and multiple or statements.
  
  Y at - it another game of logic, I could use to improve this query, using possibly not the while loop / or statements?

  Hi again:

  This is the query, reformatted in the form of a function, exectuing the same thing I did in the above query:

  1 row selected.
  

  The only variable not factored is holiday, but I saw that you were for them in your LOOP function either.

  Due to the nature and variability holiday, it is better to have a table with the listed holidays, and those who could be elminated of charges together in the same 'exculsions' query where I used the TO_CHAR and DECODE to exclude the Fri, sat and Sun.
