• Duplicate values generated by an Oracle sequence

  Hello

  Since a few days we are facing a weird problem in our application where the sequences seem to be generating duplicate values. Previously I thought is this is not possible, but now it seems to be a problem. Here are the details:

  Select * from v$ version;

  Oracle Database 11 g Enterprise Edition Release 11.2.0.2.0 - 64 bit Production

  PL/SQL Release 11.2.0.2.0 - Production

  CORE Production 11.2.0.2.0

  AMT for Linux: Version 11.2.0.2.0 - Production

  NLSRTL Version 11.2.0.2.0 - Production

  We use to insert it into a table column of the last sequence value that is of course the primary key of the table column. Today, we received a violation of unique constraint on the column of the primary key (which is driven by the sequence). Below is the last value of the PK column

  SELECT MAX(PCCURVEDETAILID) OF T_PC_CURVE_DETAILS;

  162636

  and below, was the last value in the sequence that has been less than the PK column

  SELECT S_PCCURVEDETAILS. NEXTVAL FROM DUAL;

  162631

  Then we checked the data of the user_sequences and found the next sequence value (LAST_NUMBER) to be 162645 which was greater than the current value of the sequence:

  Select * de user_sequences one où a.sequence_name as "S_PCCURVEDETAILS" ;

  SEQUENCE_NAME

  MIN_VALUE

  MAX_VALUE

  INCREMENT_BY

  CYCLE_FLAG

  ORDER_FLAG

  CACHE_SIZE

  LAST_NUMBER

  S_PCCURVEDETAILS

  1

  1E + 27

  1

  N

  N

  20

  162645

  I then modified the nocache sequence:

  change sequence S_PCCURVEDETAILS NoCache ;

  Select * de user_sequences one où a.sequence_name as "S_PCCURVEDETAILS" ;

  SEQUENCE_NAME

  MIN_VALUE

  MAX_VALUE

  INCREMENT_BY

  CYCLE_FLAG

  ORDER_FLAG

  CACHE_SIZE

  LAST_NUMBER

  S_PCCURVEDETAILS

  1

  1E + 27

  1

  N

  N

  0

  162633

  SELECT S_PCCURVEDETAILS. NEXTVAL FROM DUAL;

  162632

  We also face the same type of problem of violation of primary key to another sequence-driven table, a few days before.

  In our code, I also checked that the primary key in the table value is inserted using only the value of the sequence.

  Can anyone please suggest any reason this issue for

  Concerning

  I faced a similar problem about 3 years ago. Here's the story, suddenly in my UAT environment a job that inserts data in some tables began to throw exceptions of primary key violation. After investigation, I found that the sequence is x, but the primary key for the table is x + y. investigation more - DBA moved all production data without even notifying the application support team.

• Package to generate random values, based on a model

  I need to generate thousands of test strings based on a template (LLNNNNLL, where L stands for letter and N represents the numbers).
  I was able to create, on a table, any useful combination: the next step is to get that 'good' a few tickets.
  
  My problem is that using the following syntax I get tickets with "close to" number... just because I created using a sequence

  SELECT TICKET_CODE
  FROM TICKET_WELL SAMPLE (1) 
  WHERE OWNER = 'OWNER_NAME'
  AND rownum < 10;

  I mean: AB1001CD, AC1003CB, BB1002AD...
  while I need to get these tickets: AB1001CD, AC4667CD, SD8592GD etc...
  
  First question: is there a like DBMS_RANDOM package that accepts as input a boss so I can simply replace MY package to create the TICKET_WELL table?
  Second: Is there another way (right) to select a table trying to get the lines in a random order?
  Third: If both answers are not... is there a way to mix the rows of a table to another?
  
  Any suggestions are welcome.
  
  Thank you

  Here's a function I hit upwards to generate a randon number, based on an input mask.

  create or replace
  function random_string( p_mask           in varchar2)
  return varchar2
  as
  v_random_number integer;
  v_random_letter varchar2(1);
  v_mask varchar2(20) := p_mask;
  v_character varchar2(1);
  v_random_string varchar2(20);
  begin
  for i in 1 .. length(v_mask)
  loop
  if substr(v_mask,i,1) = 'L'
  Then
      v_random_number :=  dbms_random.value(1,26);
      v_character := chr(64+v_random_number);
  elsif substr(v_mask,i,1) = 'N'
  then
     v_random_number := dbms_random.value(0,9);
     v_character     := v_random_number;
  end if;
  v_random_string := v_random_string||v_character;
  end loop;
  return v_random_string;
  end;
  

  To select lines in a random order, you need to store the random number with a column, for example rowno and create an index on rowno.

  create table random_rows
  (rowno number,
    random_string varchar2(20)
  );
  

  then to get a random line, you can use

  declare
  v_rowno integer; -- must be integer
  begin
  v_rowno := dbms_random.value(1, v_rows_in_table);
  select random_string
  into v_random_string
  from random_rows
  where rowno := v_rowno;
  end;
  

  You can also replace the random line of the next generated random_string.
  The only thing is that you can not guarantee that the random_string is unique,
  If you need a unique index on the column of random_string, and he tries to insert a duplicate, you should try to insert another random number;

  Not a bad homework problem.  Do it with pencil and paper.  Write your table and pretend you're the computer.  What you want to do (step by step)?  What questions do you have?

  Now that the translation a bit to computers.  You mentioned that the data is in an array of strings.  What structures (LabVIEW) work with tables?  [Do you know how to work with tables?  [Otherwise, review some of LabVIEW Tutorial material - see top right of the first page of the Forum].  What do you know about channels?  What questions you need to ask questions on the channels?  What do you know about string functions?

  Watch these things in some LabVIEW code, 'feed' some data and see what he does.  If it seems to do things "unexplained", you can try to look at the block diagram to run by turning the performance highlight (and if you don't know what that means, use the help of LabVIEW and see the tutorials).

• Check all the duplicate values in the column COUNT()

  Hello
  
  I'll do some tests, and for this I need to retrieve data based on a single column for example test_data_col, which-
  1 to 3 or more count (test_data_col) for a given set of columns for example grp_col1, grp_col2, grp_col3 group
  2. overall recovered lines, this particular column has some duplicate values. I don't need displayed duplicates, just whether or not duplicates exist.
  
  Which could explain what I'm trying to do -
  
  grp_col1, grp_col2, grp_col3, test_data_col
  
  1, A, xyz, HELLO
  1, A, xyz, HELLO
  1, a, xyz, BYE
  1, A, xyz, goodbye
  
  2, C, pqr, WELCOME
  2, C, pqr, GOOD MORNING
  2, C, pqr, BAD MORNING
  
  So for condition 1, I do something like that.
  

  SELECT COUNT(test_data_col) cnt, grp_col_1, grp_col2, grp_col3
  FROM test_tab
  GROUP BY grp_col_1, grp_col2, grp_col3
  HAVING COUNT(test_data_col) >= 3;

  In this request, I want to do something that will tell me if the aggregate COUNT (test_data_col) has all the duplicate values it contains. Yet once, display the duplicates is not important here.
  

  SELECT COUNT(test_data_col) cnt, grp_col_1, grp_col2, grp_col3,
  /*some logic*/ dup_val
  FROM test_tab
  GROUP BY grp_col_1, grp_col2, grp_col3
  HAVING COUNT(test_data_col) >= 3;

  With the correct to replace coding / * some * logic /, I have following values.
  
  CNT, grp_col_1, grp_col2, grp_col3, dup_val
  
  4, 1, a, xyz, Y
  3, 2, C, pqr, N
  
  I have dup_val column to explain what I'm trying to achieve... Another way to know the existence of duplicates in the aggregate count will be fine.
  
  My version of Oracle's Oracle Database 11 g Enterprise Edition Release 11.1.0.7.0
  
  Do you like the answer!

  Your somewhere logical can be like that

  case when COUNT(test_data_col) != COUNT(distinct test_data_col) the 'Y' else 'N' end dup_val

  You can do this with all values.

  Display a test script complete (including CREATE TABLE and INSERT statements for some examples of data with your query) for people who want to hellp you can recreate the problem and test their ideas.
  It is very difficult to tell what you're doing wrong without knowing what you are doing.

• Returns all the duplicate values in object lookup (PHP, drop-down list)

  Hi, I have a PHP page I designed as a search page. I have a number of drop-down lists that get their dynamic values from the fields in a MySQL database.

  At present, if there are any entries that have duplicate values in a certain area, they are all listed, in the order of the index database. For example:

  City:

  Derby

  Stoke

  Stafford

  Stoke

  Derby

  Derby

  Stoke

  etc...

  Now, I want to do is be able to show all results for a given city. In the find what drop-down list box, I would than each of the cities to appear only once rather than every time it is registered. included in this, I would like the page of results to then display ALL results that match this search criteria.

  Thus, in the example above, "Derby" appears only once, but when the user has selected 'Derby', it would return all three results in the results page.

  My results page is built on a dynamic form, so I am confident that the results page would make it according to the needs. However, how can I get the drop-down list box to ask him?

  > 'SELECT DISTINCT table1.champ1, table1.champ2, table1.champ3 FROM Table1 ";

  Duplicate rows to remove the DISTINCT keyword strength SQL. In other words, that it will only return the unique combinations of fields in your selection list. If you examine your results set, you will see that each line is separate, although there may be duplicates in a particular area. Because you want to populate a drop-down list, you must include a field in your select list only, otherwise you get of the dupes.

  I would like on the following query select the value of the new_cost of the column that belongs to the line with the new date in the column m.creation_date, instead of using max (new_cost)

  and m.inventory_item_id = s.inventory_item_id
  group by s.segment1, s.segment2, m.organization_id 
  order by s.segment1, s.segment2, m.organization_id

  Hello

  Another way is to use the FIRST aggregation or the LAST function:

  select    s.segment1, segment2, m.organization_id, sum(primary_quantity)
  ,       MAX (new_cost) KEEP (DENSE_RANK LAST ORDER BY m.creation_date NULLS FIRST)     AS latest_new_cost
  from        inv.mtl_material_transactions       m
  ,        inv.mtl_system_items_b       s
  where       s.segment2          = 1000435
  and        m.organization_id     = 83
  and       s.organization_id     = 136
  and       m.inventory_item_id     = s.inventory_item_id
  group by  s.segment1, s.segment2, m.organization_id
  order by  s.segment1, s.segment2, m.organization_id
  ;
  

  MAX (new_cost) tells what to do in the case of a tie (where two or more lines in the same group have same latest date_creation). MAX means taking the biggest contenders. If these links are impossible to your table, then it does not matter if you say MAX or MIN it.

  If it's an array you want to deduplicate then here is a script [for use in the Script Processor] I prepared earlier:

  var result = new Array();

  var added = new Object();

  If (input1 [0]! = null)

  {

  for (var i = 0; i)< input1[0].length;="">

  {

  var point = input1 [0] [i];

  If (! added [item])

  {

  added [item] = 1;

  result [result. Length] = item;

  }

  }

  }

  Output 1 = result;

• reload the page when SQL query returns a value

  Hello world

  the title of this discussion may seem strange, but I'll try to explain why I need this:

  A user has the ability to connect on my APEX application. There are several tabs in my application that are visible only if a certain SQL statement returns a value which is not the case by default. The user has also the ability to download a file that is transferred to an external system that analyzes the file and writes the data in the database. During this writing process - which may take several minutes - conditions for some of the tabs to show the will becomes real (-> the query will return a value). When the user refreshes the page manually, the tabs will be displayed. However, I want the tabs will appear automatically when the condition is met.

  Is it possible to refresh the page as soon as the query returns a value? It is perhaps possible to check it on the client side and trigger a refresh of the page when the condition is met. It would be even better if only the tabset has been updated, but refreshing the full page is fine as well.

  Thank you!

  Here is an overview of how it can be done

  This is possible thanks to a dynamic action being performed on a timer.

  View default tabs and dynamic action hide them on loading the page if they are not to be considered

  Create a dynamic action that will execute your query every 5 seconds or more

  If the query returns data, you can use the dynamic action to show your tabs using javascript

  Declaratively reading the value of the attribute of the currently selected line

  It is very common that when a line is selected in a table, you can update

  other fields in the user interface or call some specific operations with attributes of the selected

  line. There is an easy way to retrieve the attributes you want for the current of line

  definition of the attribute for the attribute binding.

  To set the attribute binding, do the following:

  1. double-click on the file page definition to open the presentation Editor.

  Alternatively, if you have the JSF page opened in the designer

  window, and then by selecting the links tab will open the corresponding

  page definition file editor.

  2. Select the links and the executable tab and click the Green plus icon to

  create a control's binding icon that will be displayed on the bindings panel.

  3. in the dialog window insert an element, select the generic category of links (if it)

  is not selected by default) in the menu drop down and select attribute values

  as the point to be created. Click OK to proceed to the next step. In the

  Create the attribute Binding dialog box, select the desired data source

  (instance of the view object) and then the attribute you want to read

  the line selected in the data source. Click OK to have the dialog box.

  The following is an example for a binding attribute value defined by choosing the

  Collection Departments as data source:

  It's in the page definition XML file

  ID = "DepartmentName" >

  Once you have defined the attribute bindings, you can refer to them using the

  EL of the client binding expression. For example, the value of the previous attribute

  reference can be made using the expression of ADF link as follows:

  #{bindings. DepartmentName.inputValue}
