• Bulk collect with sequence Nextval

  Hello
  
  
  Oracle Database 10 g Enterprise Edition Release 10.2.0.4.0 - 64 bit
  
  
  Had a doubt about the collection in bulk with nextval sequence. You need to update a table with a sequence of Nextval.

  Hello

  It depends on what results you want. All updated rows would take the same value, or should all get unique values?

  Whatever it is, you don't need the sliders and loop. Just a simple UPDATE statement.

  If each line requires a unique value of the sequence, then

  UPDATE  loads
  SET     prop_id     = prod_id_s.NEXTVAL
  WHERE     prop_id     IS NULL
  ;
  

  If all the lines that have a need to the same value null, then:

  SELECT     prod_id_s.nextval
  INTO     v_prop_id
  FROM     dual;
  
  UPDATE  loads
  SET     prop_id     = v_prop_id
  WHERE     prop_id     IS NULL
  ;
  

  Don't forget to declare v_prop_id as a NUMBER.

  I hope that answers your question.
  If not, post a small example of data (instructions CREATE and INSERT, only relevant columns) for all the tables and the involved sequences and also publish outcomes from these data.
  If you ask on a DML statement, such as UPDATE, the sample data will be the content of the or the tables before the DML, and the results will be the State of the or the tables changed when it's all over.
  Explain, using specific examples, how you get these results from these data.
  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

• In bulk vs cursor loop for

  Hello
  
  I'm on a mission :)
  
  I want to convince our development department to encourage loose on cursor for loops. But it is more difficult to do what I expected. Just a link to many Web Sites with well-known people, saying ' use in bulk "is not enough. So, I'm going to create a unit test that measures the difference.
  
  But 11g (also 10g) is smart. Simple test cases are converted. Oracle ignores the cursor for loop and do as a statement in bulk. What can I do against it without changing the settings?

  Does anyone know a little trick to prevent oracle to optimize this cursor for loop? Perhaps via the compiler settings or something with the recursive function calls or anything like that.
  DML incidentally is no option, because this will lead to discussions with the wrong focus.

• bulk collect with limit

  code is: cursor here can fetch a large amount of data (22000 records). So I have to go with the limit clause. I use two foralls. This code snippet is correct with regard to the two foralls, exit and % bulk_rowcount sql statement? I have to use in production. Is there something that can break the code?
  
  OPEN c1;
  LOOP
  C1 FETCH BULK COLLECT WITHIN the limits of the 100 id_array;
  FORALL i IN id_array. FIRST... id_array. LAST
  Update statement;
  BECAUSE me IN id_array. FIRST... id_array. LAST
  LOOP
  v_cnt: = v_cnt + SQL % BULK_ROWCOUNT (i);
  END LOOP;
  FORALL i IN id_array. FIRST... id_array. LAST
  Insert statement;
  WHEN id_array EXIT. COUNT = 0;
  END LOOP;
  CLOSE c1;
  
  In addition, how context switching works when we use the llimit clause?
  without limit:
  collection is completely filled. then prepares to all the DML statements and go to sql and exeutes one by one.
  right?
  tasted clause say limit = 100
  100 indexes collection gets populated.then prepares all the DML statements for these 100 indices and go to the DTF sql and exeutes. And then back to pl/sql. fills the same 100 indices collection with 100 records and prepares the DML and goes to sql to run and returns to pl/sql and so on? Is this true?
  right?

  large volume of data (22000 records)

  This isn't a large volume of data.

  In addition, how context switching works when we use the llimit clause?

  Commit point has nothing to do with how many rows treat you. It's purely commercial leads. Your code implements a commercial operation, right? So if you're getting into before any trancaction (from the commercial point of view) other sessions will be already see changes that are (from a business point of view) incomplete. In addition, what happens if rest of trancaction (from the commercial point of view) goes down?

• move the MCs with loop for?

  I am trying to find a way to move video clips with a for loop

  I have 10 points called t1d-dt10, and I want to be able to put them all to y = 200.

  I understand that I can put i = 1; i < 11; i ++

  as

  for (i = 1; i < 11; i ++) {}

  DT i._y plus 200 ;}

  or

  for (i = 1; i < 11; i ++) {}

  String("DT"+i)._y = 200 ;}

  but the rest is a mess, and does not, work or glitches. I still have to find a loop help file for the movement of several video clips.

  If you just want to immediately change the positions of the bodies, then using a for loop works fine, you just use the notation of support [] to have the strings to be interpreted as the name of the instances...

  for (i = 1; i<>

  This ["dt" + i] ._y = 200;

  }

• Do nothing in the case structure with loop For

  Hello

  I am trying to extract data from my signal (0.3 0.4 0.6...). I want to extract values greater than 0.5 and put it in a table. If I use a loop For which I can determine each index of my data to be compared and it happened in the structure of the case. In the 'Real' box, I wanted the value to extract outside the loop For. And I want to "do nothing" if my value falls within the box 'False. ' However, it displays error, saying "' Tunnel: lack of assignment to the tunnel '."

  I tried to select 'Default', but it does not work since I use a Boolean comparison. I tried to use the registry to shift, but in vain too.

  Someone could guide me on this to extract only a value greater than 0.5 and index them?

  For example "0.6 0.7 0.8; 3 4 7 index.

• Table row with loop for each group to set the variable.

  HI: There is probably a simple answer for this, but I don't the have not found...
  
  I have a single row table to move through a group to set a variable containing a sum running. I'm not display the amount in the table but when I saw the report, I see that the table is expanding (add lines) for each loop.
  
  The only line table has 3 columns.
  
  1st column
  <? for-each: AC_GROUP? >
  
  2nd column
  <? xdoxslt:set_variable ($_XDOCTX, 'xAmtVar', xdoxslt:get_variable($_XDOCTX,'xAmtVar') + CURRENT_AMOUNT)? >
  
  3rd column
  <? end foreach? >
  
  Can I use <? for each group? > or something else. My requirement is to set the value of the variable with the total running, but because the loop is adding lines for each value he travels (though not displayed), it's also affecting other areas of the presentation of the page.
  
  Hope it makes sense. Thanks in advance.

  You can do it many ways.

  No need to loop
  You can create a variable and specify the amount of the sum directly to that.

  or

  loop through, then add as you do.

  give any space or enter characters in a word between them, just put it in a single form field will be

  But as I said, I'd definitely go with the first option.

  3 table parameter means;
  "> create or replace the NUMBER TABLE (10.2) of TYPE"NUMBER_ARRAY"AS"
  
  Questions
  Q1. Can I sort and sum with table group?
  Q2. Type of income can be increased or decreased subsequently. This is why I don't want to fix it.
  How can I implement this dynamically?
  
  
  Any good idea?
  
  Thanks in advance
  Dan

  You are looking for something like this

  create or replace type objIncome as object(incomeType varchar2(50), income number(10,2))
  /
  create or replace type tblIncome as table of objIncome
  /
  declare
    lIncomeTbl tblIncome := tblIncome();
  begin
    lIncomeTbl.extend;
    lIncomeTbl(1) := objIncome('cash','500');
    lIncomeTbl.extend;
    lIncomeTbl(2) := objIncome('Service','100');
    lIncomeTbl.extend;
    lIncomeTbl(3) := objIncome('cash','100');
    lIncomeTbl.extend;
    lIncomeTbl(4) := objIncome('penalty','50');
    lIncomeTbl.extend;
    lIncomeTbl(5) := objIncome('Service','200');
    lIncomeTbl.extend;

    for i in (select incometype, sum(income) income

  This ["m2" + i] .addEventListener (MouseEvent.Click, clicking);
  }
  }

  function clicking(event:MouseEvent):void {}
  trace ("I am clicking on the button" & event.target.name);
  }

  Remember that you have to work with the positioning and the TextFields overlap takkis, that the click is possible only in a minor fraction of the takkis.

• UNION operator with BULK COLLECT for one type of collection

  Hi all
  
  I created a table as given below:
  create or replace type coltest is table of number;
  
  Here are 3 blocks PL/SQL that populate the data in variables of the above mentioned type of table:
  
  
  BLOCK 1:
  
  DECLARE
  col1 coltest: = coltest (1, 2, 3, 4, 5, 11);

  Can someone explain please the output of the BLOCK 1 and 2? Why not in bulk collect in col1 and col2 11 return as County?

  If I remember correctly, the part INTO the query to initialize the collection in which it will collect the data, and you gather in the collections that you are querying, you end up deleting the data out of this collection until she is interrogated.

  Not really, wise trying to collect data in a collection that you are querying.

• Using bulk collect into with assistance from the limit to avoid the TEMP tablespace error run out?

  Hi all

  I want to know if using bulk collect into limit will help to avoid the TEMP tablespace error run out.

  We use Oracle 11 g R1.

  I am assigned to a task of creating journal facilitated for all tables in a query of the APEX.

  I create procedures to execute some sql statements to create a DEC (Create table select), and then fires on these tables.

  We have about three tables with more than 26 million records.

  It seems very well running until we reached a table with more than 15 million record, we got an error says that Miss tablespace TEMP.

  I googled on this topic and retrieve the tips:

  Use NO LOG

  Parallel use

  BULK COLLECT INTO limited

  However, the questions for those above usually short-term memory rather than running out of TEMPORARY tablespace.

  I'm just a junior developer and does not have dealed with table more than 10 million documents at a time like this before.

  The database support is outsourced. If we try to keep it as minimal contact with the DBA as possible. My Manager asked me to find a solution without asking the administrator to extend the TEMP tablespace.

  I wrote a few BULK COLLECT INTO to insert about 300,000 like once on the development environment. It seems.

  But the code works only against a 000 4000 table of records. I am trying to add more data into the Test table, but yet again, we lack the tablespace on DEV (this time, it's a step a TEMP data)

  I'll give it a go against the table of 26 million records on the Production of this weekend. I just want to know if it is worth trying.

  Thanks for reading this.

  I really need check that you did not have the sizes of huge line (like several K by rank), they are not too bad at all, which is good!

  A good rule of thumb to maximize the amount of limit clause, is to see how much memory you can afford to consume in the PGA (to avoid the number of calls to the extraction and forall section and therefore the context switches) and adjust the limit to be as close to that amount as possible.

  Use the routines below to check at what threshold value would be better suited for your system because it depends on your memory allocation and CPU consumption.  Flexibility, based on your limits of PGA, as lines of length vary, but this method will get a good order of magnitude.

  CREATE OR REPLACE PROCEDURE show_pga_memory (context_in IN VARCHAR2 DEFAULT NULL)

  IS

  l_memory NUMBER;

  BEGIN

  SELECT st. VALUE

  IN l_memory

  SYS.v_$ session se, SYS.v_$ sesstat st, SYS.v_$ statname nm

  WHERE se.audsid = USERENV ('SESSIONID')

  AND st.statistic # nm.statistic = #.

  AND themselves. SID = st. SID

  AND nm.NAME = 'pga session in memory. "

  Dbms_output.put_line (CASE

  WHEN context_in IS NULL

  THEN NULL

  ELSE context_in | ' - '

  END

  || 'Used in the session PGA memory ='

  || To_char (l_memory)

  );

  END show_pga_memory;

  DECLARE

  PROCEDURE fetch_all_rows (limit_in IN PLS_INTEGER)

  IS

  CURSOR source_cur

  IS

  SELECT *.

  FROM YOUR_TABLE;

  TYPE source_aat IS TABLE OF source_cur % ROWTYPE

  INDEX BY PLS_INTEGER;

  l_source source_aat;

  l_start PLS_INTEGER;

  l_end PLS_INTEGER;

  BEGIN

  DBMS_SESSION.free_unused_user_memory;

  show_pga_memory (limit_in |) "- BEFORE"); "."

  l_start: = DBMS_UTILITY.get_cpu_time;

  OPEN source_cur.

  LOOP

  EXTRACTION source_cur

  LOOSE COLLECTION l_source LIMITED limit_in;

  WHEN l_source EXIT. COUNT = 0;

  END LOOP;

  CLOSE Source_cur;

  l_end: = DBMS_UTILITY.get_cpu_time;

  Dbms_output.put_line (' elapsed time CPU for limit of ')

  || limit_in

  || ' = '

  || To_char (l_end - l_start)

  );

  show_pga_memory (limit_in |) "- AFTER");

  END fetch_all_rows;

  BEGIN

  fetch_all_rows (20000);

  fetch_all_rows (40000);

  fetch_all_rows (60000);

  fetch_all_rows (80000);

  fetch_all_rows (100000);

  fetch_all_rows (150000);
