• 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.

  Back AFTER using the exception block is fine as long as your code actually REACHED the exception block.

  When there are no errors, then your code will not enter the exception block, but you still NEED to return a value, since it is what functions a function wants to return a value, that's what the functions are made for.

  Spot the differences between the following 3 functions. Understand how they work.

  The first function has only a return in the exception block but runs correctly. Result: error, because the back is missing in the code block.

  The second function has a return in the exception block and one in the block of code and runs correctly. Result: no error, because the return is not missing in the code block.

  The third function has a return in the exception block and one in the block of code and is forced into an error. Result: no error, because the return of the exception handler is used (instead of retriggering of the error, which you would normally do).

• 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.

• XQuery SQL function

  Hello
  
  In a query XQuery is posssible to call a function or procedure SQL (PL / SQL)?
  Here is an example of what I had accomplished:
  
  
  SELECT THE PRD. XMLCOLUMN of
  XMLTABLE (' for $i in ora: view("P_iXXX")/LINE)
  $j in ora: view("P_jXXX")/LINE.
  where
  ($i / NSU_xxx = $j/NSU_xxx)

  $i / NSU_xxx,

  Return()
  }

  () "PATH of XMLType 'XMLCOLUMN' COLUMNS 'resultsqlfunction' INTEGER PATH 'xsql_xxx' INTEGER ACCESS to 'NSU_xxx' path 'NSU_xxx', '.') as the PRD;
  
  Thanks in advance for your answers
  François

  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.
  Provides the steps necessary to reproduce the problem, including some examples of data.

• 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?

• Pass a list of values to a pl/sql function

  I would like to pass a list of values to a pl/sql function where the list will be used in an IN clause. Ideally, I would like to do the following:
  
  CREATE or REPLACE FUNCTION (dept_list in varchar2)
  Start
  Select... where dept in (dept_list);
  
  use: process_list ('7730,7735,7740,7745');
  
  I can't find an example to do based on pl/sql, but it seems feasible.
  Is there a way to do this?

  use: process_list ('7730,7735,7740,7745');

  The first thing is that you need an appropriate data type for storing a list of numbers. A unique value that look you like a list of numbers, is not actually a list of numbers but a single character value.

  This example uses the built in odcinumberlist data type in a procedure, you can do the same in function

  Re: Pass an array to an Oracle stored procedure

  If you have an older version of the database, you may need to create your own type with the same definition of odcinumberlist.

  Can someone help me how to call...

  Call it in function, not as a procedure you do

  try {
  String stmt =
  "begin :1 := XXWFS_SANCTIONS_PKG.CHECK_SANCTION(:2,:3,:4,:5,:6,:7,:8,:9,:10,:11,:12); end;";
  st = getDBTransaction().createCallableStatement(stmt, 0);
  st.registerOutParameter(1, Types.VARCHAR);
  st.setNull(2, Types.VARCHAR);
  st.setNull(3, Types.NUMERIC);
  st.setObject(4, customerID);
  st.setNull(5, Types.NUMERIC);
  st.setNull(6, Types.NUMERIC);
  st.setObject(7, locationID);
  st.setNull(8, Types.NUMERIC);
  st.setNull(9, Types.NUMERIC);
  st.setObject(10, tail);
  st.setObject(11, tailNum);
  st.setObject(12, result);
  st.execute();
   = st.getString(1);
  

• Action dynamic pl/sql function setvalue

  Hello
  
  I have a table of currency with Exchange rate column.
  I've created a form that allow the user to select the currency of the table and enter the rate elements of page Px_RATE.
  I want to implement using dynamic action in the apex 4
  Please help me on this case
  
  Thanks and greetings

  Hello

  You can do this by defining a dynamic action as follows...

  #1-do a right click on the item page to select the currency (let's call it P1_CURRENCY for this example) and select 'create the dynamic Action '.

  #2-Select 'Advanced' that we use the type of dynamic action "set the value, which is not available in the 'Standard' of the Assistant branch.

  #3-name your dynamic action, say "RATE of GETTING", click on "next".

  #4-let the "When" default attributes, it simply defines that the dynamic action is triggered whenever the currency item, click 'next '.

  #5-pour the "real Action > Action' select 'Put the value'"

  #6-think if you want to set the value on the loading of the page of the dynamic action too, if so let the 'Fire when loading the Page' box checked.

  #7 [assuming that you have a simple API of PL/SQL that returns the rate of say get_rate, for example] select 'Set Type' of the 'body of the PL/SQL function.

  #8-pour "Body of the PL/SQL function" says something like:

  return get_rate(:P1_CURRENCY);
  

  #9 "Page to submit elements", specify the element to P1_CURRENCY currency, and then click "next".

  #10-pour "items affected" specify "Item" and then select the page element where you want to return the value of the rate, say P1_RATE.

  #11-click on 'create '.

  Let me know if it works for you or if you have other questions.

  Kind regards
  Anthony.

• assign a value to a text element using the PL/SQL function body

  Hello
  
  I want to assign a value to a text element using PL/SQL function body option in the Source elements. But the below error when I try to apply it.
  
  Source code:
  
  declare
  name varchar2 (100);
  Start
  If v ("P3_CREHIDD") = 'Edit' then
  Select ename in the name of cpy_emp where empno = v('P3_EMPNO2');
  
  end if;
  end;
  
  
  ERR-1904 unable to calculate the default item: type = computation_type = function body declare name varchar2 (100); so start v ('P3_CREHIDD') = 'Edit' and then select ename in the name of cpy_emp where empno = v('P3_EMPNO2'); end if; end;.
  
  Thank you
  David.

  Hello

  Your body of the function doesn't return anything.
  Maybe it works

  declare
    l_name varchar2(100);
  begin
    if v('P3_CREHIDD') = 'Edit' then
      select ename
      into l_name
      from cpy_emp
      where empno = v('P3_EMPNO2');
    end if;
    RETURN l_name;
  end;

• call the XMLQuery pl sql function

  Hi all.
  Is anyone know how to call the function sql pl by XMLQuery query?
  
  For example:
  
  I pl sql function "test()".
  
  And the desire to write this way:
  
  Select XMLQuery (' let $t = test()' returning content);
  
  How to change to work?
  
  Thanks for all the answers.
  Kind regards
  Anton.

  following should give you an idea:

  SQL> select xmlquery(('if (2*2 = ' || power(2,2) || ') then 1 else ()') returning content) x from dual
  
  X
  -----
  1
  1 row selected.
  

• Allowing access only through a PL/SQL function

  What is the technique of letting a user to do something by a PL/SQL function that would normally not have the privilege to do so, without granting the possibility to do outside the PL/SQL function?
  
  I have a need to allow a user to change the global_name of the database, in the resolution of ORA-02082 errors. In short, the product using Oracle (we can not change code) loopback database links, and the only way to drop them (according to the Oracle support) is to temporarily change the global_name, drop the link and change the global_name return.
  
  This happens on a semi-regular basis, so rather than having to involve a DBA, I favor.
  
  My thought was to create a PL/SQL procedure that performs the Rename/move/rename. I don't want the user to be able to change the global_name of DB to what he wants, but I want him to have the possibility to change through the PL/SQL procedure at will.
  
  My question is, how to do this without allowing the user to update on sys.global_name?
  
  Let's see:
  
  (1) create a role (say LOOPBACK_DBLINK_DROPPER)
  (2) create a procedure (say LOOPBACK_DBLINK_DROP) makes the Rename/move/rename
  (3) grant and then execute the procedure to the role
  (4) ??? .. .the I need to give an update on sys.global_name for the role. But if I then assign the role to a user, is not that means he can also update sys.global_name on its own without using the procedure, because it would have the sys.global_name privilege update?

  Create the schema belonged procedure that has the necessary privileges.
  GRANT EXECUTE on LOOPBACK_DBLINK_DROP to NON_PRIV_USER

  That's all!
