• 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

  Deepak

  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.

  Morale - pretty obvious

• 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
  

• Obtaining duplicate values.

  Hi all
  
  I have a table with collums as follows:
  

  create table uni_ids 
  (ID varchar2(10),
   field number,
   activity number,
   frequence number,
   field_1 number,
   field_2 varchar(100));

  and the following data:

   insert into uni_ids (ID,field,activity,frequence,field_1,field_2) values('N1999',1,2,600,15,'SOME TEXT');
   insert into uni_ids (ID,field,activity,frequence,field_1,field_2) values('N1999',1,2,600,15,'SOME TEXT');
   insert into uni_ids (ID,field,activity,frequence,field_1,field_2) values('N1990',1,3,600,15,'SOME TEXT');
   insert into uni_ids (ID,field,activity,frequence,field_1,field_2) values('N1990',1,4,600,15,'SOME TEXT');
   insert into uni_ids (ID,field,activity,frequence,field_1,field_2) values('N1990',1,2,600,15,'SOME TEXT');
   insert into uni_ids (ID,field,activity,frequence,field_1,field_2) values('N1991',1,2,600,15,'SOME TEXT');
   insert into uni_ids (ID,field,activity,frequence,field_1,field_2) values('N1991',1,3,600,15,'SOME TEXT');
   insert into uni_ids (ID,field,activity,frequence,field_1,field_2) values('N1991',1,3,600,15,'SOME TEXT');
   insert into uni_ids (ID,field,activity,frequence,field_1,field_2) values('N1992',1,2,600,15,'SOME TEXT');
   insert into uni_ids (ID,field,activity,frequence,field_1,field_2) values('N1997',1,2,600,15,'SOME TEXT');
   insert into uni_ids (ID,field,activity,frequence,field_1,field_2) values('N1995',1,8,600,15,'SOME TEXT');

  What I would get with my querry is duplicated files, so resoul of it should be like:
  

  ID               field     activity     frequence          field_1               field_2
  N1999          1          2               600                    15                    SOME TEXT
  N1999          1          2               600                    15                    SOME TEXT
  N1991          1          3               600                    15                    SOME TEXT
  N1991          1          3               600                    15                    SOME TEXT

  Insofar as that I came up with this SQL that does not work as it should. It returns the other (do not duplicate) values as well...
  

  select
  
      a.id,
      a.field,
      a.activity,
      a.frequence,
      a.field_1,
      a.field_2
      
  from uni_ids a
  
  where a.rowid <> (
  select 
    max(b.rowid)
  from  uni_ids b
  where a.id= b.id 
        and a.field = b.field 
        and a.activity = b.activity)
  
  ORDER BY a.id;

  If anyone can help please post solution
  
  Thank you!

  Select
  a.ID,
  a.Field,
  a.Activity,
  a.FREQUENCE,
  a.Field_1,
  a.Field_2
  of uni_ids one
  where
  (id, domain, activity, frequency, Champ_1, Champ_2) in
  (select id

• 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.

  Use the folliwng in PRE-INSERT-TRIGGER.

  There is not a lot of changes with the exception

  where CANCELLATION_USERID =: CANCELLATION_USERID;

  and

  If valExists > 0 then

  declare
  
   valExists number;
  
  begin
  
   select count(*) into valExists
   from USERDELETION
   where CANCELLATION_USERID = to_char(:CANCELLATION_USERID);

• How to select several values with a select statement with other columns

  Hi all

  I have a small request related to the selection of values in a table.

  create table employees (eid, ename varchar2 (20));

  insert into employee values (1, 'Nik');

  insert into employee values (2, "Prashant");

  commit;

  
  Now, I have a small list of say A, b, C, I want to choose this list with all the lines as

  with test1 as)

  Check the eid, ename for employee

  )

  Select eid, ename, 'A' col1 in test1

  UNION ALL

  Select eid, ename, 'B' col1 in test1

  UNION ALL

  Select eid, ename, 'C' col1 in test1

  but the problem with that is that in production my employee table has millions of records and it scans the employee three times table (or the number of constant values)

  Is there another way to do this.

  Thank you

  Nik

  Here is an approach with the scanning of a single table test1

  Select t.eid, t.ename, c.col1

  t test1

  Cross join (select 'A' col1 of union double all the)

  Select 'B' of all the double union

  Select the double ' C') c

• From dynamic column change for quick selection of values.

  Hello

  Requirement is based on the selection of value FAST I need to change the column values as like: "QTD_MONTH"

  
  

  for example. If the prompt value is February then the column value must be "QTD_February"

  

  

  This QTD_February is must be dynamic based on the quick selection.

  Thank you

  A Penning.

  Hello

  Instead of making the quick selection. Build separate column in the report. According to the requirement.

  Try the following formula,

  for example,.

  FILTER ("measue' to the HELP of CAST (SUBSTRING("TIME_Dimension"FROM 2 FOR 2) AS INTEGER) IN (@{wk} {26}))

  Thank you.

• How to find duplicates of a field value? For example - in a field, I have values like {123,345,346,123}, now I want to remove the duplicate value in the field so that my output looks like {123,345,346}

  How to find duplicates of a field value? For example - in a field, I have values like {123,345,346,123}, now I want to remove the duplicate value in the field so that my output looks like {123,345,346}

  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;

• By the way Select list value to another page via report link

  Hello

  I have a page 1001 with an item from the selection list (SLI), a button (BTN) and a report (EPR).

  After selecting a value of the element of selection it s possible to click on the button.

  After clicking the report button will display the data. Report structure: ID, COL1, COL2, COL3, COD values in COL1 is the links to the page 1011.

  I managed to pass the value of a column in the report, but how to pass the value of SLI this link?

  I tried: SLI, SLI, #SLI # and & SLI... but nothing has worked.

  You have an idea?

  Use the exact static text substitution method to reference the value of the element. This requires an end point ('.) ») :

• selecting a value in the drop-down list but page must not get recharged again.

  Hello
  I created a drop-down list. After you have selected a value from him, I can get a value in the box of text below according to updon one sql query. but the problem is that I HAV to select Page Action when the changed value parameter to the set value and redirect. Thanks to her whenever I have to select a value from the drop-down list, page get updated. Is there a way that will satisfy the requirement but page does not get new dependants.
  I use apex 4.2.
  Thank you

  You can create A dynamic Action to set the value while changing the value in the Select list (drop-down list).

  Event: change
  Selection type: item (s)
  Article (s): choose your selection list item
  Action: Execute the PL/SQL Code
  PL/SQL code:

  begin
  select colum_name into :Px_text_item_name from table where column_name=:px_select_list_name;
  end;
  

  Page elements to send: px_select_list_name
  Page referred to return: Px_text_item_name

  Its work for me without refreshing the page. Assume that, if you want to pass this value to the element in another page, then use the branch for redirection and assign the value to the element on the page of another.

  Thank you

• I created a PDF form with several drop downs, all with the same drop-down values. When I select a value of 1 in the drop-down list fields, it breeds in all others - which I don't want. How can I fix?

  I created a PDF form with several drop downs, all with the same drop-down values. When I select a value of 1 in the drop-down list fields, it breeds in all others - which I don't want. Can I fix?

  I am fairly new to this, but I think it has to do with the way you have drop them downs named. Copy you a then keep stick in each area? If so, that's the problem. You must rename each with a different number: Dropdown1, Dropdown2, etc. I think this might solve the problem.

• How to call a method defined in AM when I select a value in LOV

  Lets say there is a LOV. The scenario is as soon as I select a value in LOV, a method should be called I wrote in the AM. And the output of the method in an output text area.
  
  I am not able to understand how to call a method when the user selects a value from the LOV.
  
  
  This is wht I did. I had created the connection for the method. One replaced the property autosubmit to the LOV for real and in the properties of the output area, in partial submission trigger property, the ID of the LOV. But I don't have any place where I need to call the method. I'm also not able to remove a listener for action on the LOV
