Using TABLE() syntax with collection types

• Workaround solution for use af:foreach with collection

  Hello
  
  I have a n to m relationship between the two tables to TRANSFER and the USER. I've implemented this n m relationship with a third table, called USR_ASS_REL.
  
  I have a page detailedUser.jspx which gives me detailed information on all users. If I drag the DataControls USR_ASS_REL field on the screen, I create an array with all of the responsibilities of the user. But this isn't what I want. Instead, I want to print all the assignments on the screen, just separated by a semicolon (by example, assignment1; assignment2;...). I tried to use af:foreach, but that doesn't support the collections. Will there be a chance to do this in a different way? It would probably work if I create a new query asking for assignments to a user, but I don't want to create an additional query for cases like this.
  
  Thank you

  Hi John, try instead of foreach and it should work. Recent have been prety much more simply in one of my pages:

• Using nilibddc dll with Python types

  I try to use this 'DiaDEM connectivity library' with Python to read files produced by our acquisition of data in the format *.tdms system, but examples of dll are all for C and Matlab. Has anyone else done that could give me advice? I made some progress (see below) by trial and error, but it is slow and I have to get it up and running quickly. I'm trying to reproduce the functions of the C example for reading a file (no need to write again).

  I'm using Python 2.6 on a Windows XP computer.

  Here's what I have so far:

  ------------------------------------
  # Module to manage a *.tdm and a *.tdms National Instruments TDM
  files in the format #.
  #
  types import *.

  #Define of the short names for the required dll functions
  DDCOpen = windll.nilibddc.DDC_OpenFile

  DDCReadGroups = windll.nilibddc.DDC_GetChannelGroups
  DDCGroupStrPropLen = windll.nilibddc.DDC_GetChannelGroupStringPropertyLength
  DDCGroupProperty = windll.nilibddc.DDC_GetChannelGroupProperty

  # File handles are pointers to 32-bit integer
  Czero = c_int (0)
  File descriptor = point (czero)

  # Retrieve a handle to the file
  DDCErrCode = DDCOpen (' Test_0919.tdms, 'PDM' file descriptor,)
  Print (DDCErrCode) # must be zero
  MyFile = real FileHandle.contents #The file handle

  # Find several groups
  grpnum = c_int (0)
  numPtr = point (grpnum)
  DDCErrCode = DDCNumGroups (myFile, numptr)
  Print (DDCErrCode)
  # Si DDCErrCode == 0: print (numptr.contents, grpnum)

  # Read groups [UNTESTED]
  groups = c_int (0) * grpnum
  grpptr = point (groups) # must be a pointer to the memory to organize grpnum
  Number of fields DDCChannelGrouphandle
  DDCErrCode = DDCReadGroups (myFile, groups, grpnum)
  Print (DDCErrCode)
  If DDCErrCode == 0: Print (groups)

  # Length of name of the Group [UNTESTED]
  namelen = c_int (0)
  nlenptr = point (name)
  DDCErrCode = DDCGroupStrPropLen (groups [0], 'name', namelen)
  Print (DDCErrCode)
  If DDCErrCode == 0: Print (namelen)

  #Make a buffer to hold the name, then get it back [UNTESTED]
  grpname = create_string_buffer(namelen+1)

  What are you talking about? Without doubt, one of the two generates a compile exception because the data type is incorrect...

  Monica wrote:
  STOP_STAT_RES is a collection of number abd the data types Date.

  Do you mean that you have created a user-defined type (e.g. CREATE TYPE >) which has attributes NUMBER and DATE? And that STOP_STAT_RES is a collection of such user-defined? Can you post the this user-defined type declaration?

  You already have the data in a table (tab_test_data), then why don't you just use the table inside the proce_temp? Why should I set a collection type and pass it as a parameter? Collections use the expensive PGA memory. If the application that you build this way may have some serious scalability issues.

  Sort of a technical solution would be like this. You can use BULK COLLECT.

  declare
  TABLE_TYPE v_table;
  Start
  Select to bulk column_name fired in v_table

• How to use a collection type of variable binding to execute dynamic statement

  Hello

  It works very well it takes an average of 10 seconds to copy around 14 paintings. We have an obligation to bring this time to 2 seconds. An observation was the clause
  "Select test_id of ' | '. from_schema |'. Table c"in the statement sql preceding repeats for many inserts. So, we thought bulk get this set of codes of practice and use a vatiable bind to collection for the immediate run clause type. Any suggestions on how to achieve this?

  Hi André,.

  You can create new types of collection (varray/table) in two ways:
  (1) in the browser - find 'Types of data' > 'Types of Collection' node menu dropdown - there just 'create new collection type' it
  (2) in the types of data model diagram - you can create collection "some type structured" or collection of references to the it - use 'new Collection... '. "tool and click first on sight structured type and after the structured type that will contain the collection - new attribute is added to the latter and if there is none this type of collection already didn't set the new collection type are created and you can change it later.

• Can I use only the a collection of photographs with Photos Apple '&' Adobe Creative Cloud

  I am new to Adobe Creative Cloud and have used Apple base 'Photos' collect/store my photos (mainly photographs of family more than 40 years) - Great to take pictures on my iPad to show parents.

  I bought Creative cloud not only to improve potentially good photographs of family and finally properly organize them, but to use it with my new found passion for digital SLR photography.

  However, I now seem to have two series double massive photographs. The one with the Photos of the Apple and the other with Lightroom. Is there a simple way, I use two Photos Apple & Lightroom just the single series of photographs, (though that I need to make changes to the image of files/folders exclusively through Lightroom) other than to have to constantly import/export photographs of an application to the hard drive before, before import/export photos to the other application?

  Thanking you in advance,

  M.

  Hello mv.

  The time that you have moved your iPhotos to Lightroom gallery, I believe that you used the Lightroom plugin to move the library

  There is also an option while you import images from iPhoto "keep files referenced in your iPhoto library.

  

  If this option is not duplicate images.

  Please let us know if it helps.

• Issue with Collections

  I created an obj_cond object and a nested table: nt_cond of type obj_cond. In the select statement, I'm a big collect in the nested table. I have 2 questions on this note
  1. my select statement gives a few duplicate values, but I don't want duplicates. When I use the distinct clause it did not allow me to do. How can we get the separate data in the nested table?
  2. Im trying to print the output of the nested table, but I am not able to print in a syntax unique dbms_output. There is reverse?
  Please, share your ideas.

  Remember that DBMS_OUTPUT is not a display device. It is an array of strings in memory expensive server - use sparingly to save/store text lines, the customer may request from the server and make the server output.

  With regard to the display of the content of an object. It makes more sense to set the display of this once - object using a member method. For example, using the sample code that I posted above:

  Adding a new Member to the type method:

  member function Display return varchar2
  

  Implementation of the method in the body type:

  create or replace type body TSomeObject as
         ..
  
          member function Display return varchar2 is
          begin

  A single definition of the way in which the properties of the object should be displayed as a string. Now, you can simply do the following:

  I used to work with Interbase and Firebird and used databases the keyword "domain".

  I am now switchig to Oracle as a primary database and would like to find a suitable

  Variant of 'area' in Oracle such that it appears he does ' t support the standard SQL syntax.

  for example:

  Create the int2 smallint field;

  create domain id2 int2 default 0 not NULL; / * for the primary key * /.

  create domain rel2 int2 default 0 not NULL; / * foreign key * /.

  I tried a couple of approaches to achieve this "area" is:

  1. create synonym - cannot be used with the basic types;

  2. create the type - type of work, but the implementation is rather clumsy

  and can be costly in terms of performance.

  Is there something else to Oracle that can emulate the feature "domain"?

  Thanks in advence, I got really approciate any help on this.

  Alex.

  Your best approximation is CREATE TYPE, but their is nothing of what is a 100% adjustment.

  For example, if you create a domain with a check constraint you need to implement than separately on each table.

• Slider with Collection performance comparison

  Dear all,

  In my package (existing production) same cursor is opened and closed many times. What is the performance benefit or impact of this method?  What are all the oracle process will be open and close a cursor?

  In my personal opinion, instead of opening and closing several times, same cursor using the collection preferred. Am I wrong?

  [code]

  DECLARE

  v_account_no VARCHAR2 (20);

  CURSOR c1

  IS

  SELECT FROM test_table WHERE account_id account_no = 121321;

  BEGIN

  OPEN c1;

  FETCH c1 INTO v_account_no;

  -make some process

  CLOSE c1;

  END;

  BEGIN

  OPEN c1;

  FETCH c1 INTO v_account_no;

  -make some process

  CLOSE c1;

  END;

  [code]

  instead of code above can I use code below for the improvement of the performance?

  [code]

  DECLARE

  v_account_no VARCHAR2 (20);

  type v_account_type

  IS

  TABLE OF test_table.account_no%type;

  v_account typ v_account_type;

  BEGIN

  Collect SELECT account_no in bulk

  IN v_account typ

  FROM test_table

  WHERE account_id = 121321;

  FOR I IN 1.v_account typ.count - in a single loop, we can make the entire process

  LOOP

  BEGIN

  -make the entire process

  END;

  BEGIN

  -make the entire process

  END;

  END LOOP;

  Dear Billy,
  Yes you are correct. but i could not change existing package.just want to know which logic is better.
  
  Thanks.
  S.Balraj
  

  Well well, or logic is really better, because none are active parallel and thread-safe, in order to scale. This is a serialized approach - I think inevitably a problem in data bases of today as volumes are growing and processing windows are required to be decreased.

  For the existing logic remember the following.

  Hit with a single pass data when possible. Several passages are not only more I/O, but potentially see different versions of what should be a coherent set of data in the same transaction.

  Context for the SQL engine switches are expensive. But the memory of the server assigned to the private use of process, may be MORE expensive. So by all means to reduce context switches. But not at the expense of negatively impacting the server memory.

  And these 2 questions, said that the current approach used, the best approach is one implicit cursor (optimized as an extraction in bulk by the PL/SQL engine) and inside the loop to do "all treatments.

  For example

  begin
    for c in( select .. ) loop  -- use FOR UPDATE if the selected rows are changed in processing
      do all processing;
    end loop;
    commit;
  end;
  

  A minimal code and moving parts. No need for an explicit cursor. Not need to make use of explicit a collection. No need to play stupid games "buffer cache" with collections in PL/SQL.

• problem with the type of local and global

  Hi the gems...
  
  I have a plsql package. In the package, I defined a proc that takes two input parameters of type simple number and a parameter of a type of output collection.
  
  create or replace package pack_1 as body
  procedure proc_1 (p_number1 in number, p_number2 number, p_tt_table to tt_table) as
  v_tt_table tt_table:=tt_table();
  type c_ref_cursor is ref_cursor;
  v_c_ref_cursor c_ref_cursor;
  v_sql varchar2 (20000): = < a large sql using bind variables p_number1 and p_number2 >
  
  Start
  Open the v_c_ref_cursor for v_sql using p_number1, p_number2;
  loop
  extract the v_c_ref_cursor in v_tt_table;
  When the output v_tt_table.count = 0;
  for idx in 1.v_tt_table.count
  loop
  < business logic >
  end of loop
  end loop;
  close v_c_ref_cursor;
  < excpetion_block >;
  end;
  
  < several codes for the rest of the package >
  
  
  
  When I execute the proc_1 then he throws me error of data type incosistent while to fetch the v_c_ref_cursor of cursor in the v_tt_table variable.
  ORA-00932: inconsistent data types: expected - was -.
  But I have checked that the output of the query is similar with the type of variable.
  
  Now, a few facts: the tt_table of the user-defined table type is made from ot_table (create or replace tt_table to ot_table Board).
  The parent type i.e. ot_table has the same columns of this query in v_sql my proc.
  The ot_table and the tt_table are global types.
  
  But when I did these two types as local types, then the proc works very well. But I need them as global types only according to the condition in java.
  
  Please help me. The database is 11 GR 2.
  
  Thanks in advance.

  I'm trying to keep it in the simplest form... Please take a look...

  Ah... Easy to solve.

  The projection of SQL must be an object of type ot_test_type for extraction in bulk work.

  Your projection of SQL look like this:
  cursor c1 is select object_name from user_objects;

  object_name is a string - it is not of type ot_test_type.

  You must change the projection to return ot_test_type. This is done by using the default constructor for that type of object.

  For example
  cursor c1 is ot_test_type (object_name) select as the user_objects OBJECT;

  He may now be in bulk recovered in tt_test_type.
