Check if a row in a table is locked

• Update a variable based on the expiration date checking against now() in each row of a table

  I use Coldfusion 9,0,0,251028 on Windows 7 64 bit with a Microsoft Access 97 database.

  I am creating a query that loops through all the rows in a table and checks if the current date is earlier than the date of expiration or later. 

  If the expiration date column is earlier to now(), it sets the column "is_current" to 0, which is a variable that determines if a message appears on a page (breakingnews.cfm) different. 

  The column that has the expiry date is "exp_dat" in the "news" table. The query I have at the moment is:

  <cfquery name="expire" datasource="#db#">
  

  Two things:

  1 - a query will never affect rows that you did not. So if new lines have the is_current set to 0, then it's because you want to set or out in the instructions of your return or you set a default value to the column. Just make sure that you set the 1 column when you insert the new line.

  2. Why are you doing this at all? Say you run your update query (which is relatively intensive) a millisecond before the expiration of one, it will still appear on your page. Why you not just do "SELECT * FROM MaTable WHERE correspondents > now() '?

  Obviously using cfqueryparams, but this is just an example. It seems for now what you do is store obsolete data in a database and cause you more work and overhead.

• How to set Max number of rows in a table?

  Hello
  I'm working on a SCADA interface. In this application, there are different tables with vertical scroll bar.
  I prefer to make it visible only initialized lines (I've initialized 40 empty rows in a table with an array of strings). Since the window contains all 40 lines, but only 20 rows, I put the number of lines in the "table properties window" at 20; So I added a vertical scroll bar.

  Now, when a user, do scroll the scroll bar, it can check not only the initializated 40 lines, but any number of lines.
  There is a way to view only a limited number of lines?

  Thanks in advance!

  
  

• problem of adjustment of height of the rows in the tables in CS6

  I read all the debates devoted to setting the height of the rows in the tables and I can't find the answer to my problem.

  I placed a table that was created in Word.  I've done several times, but now I can not adjust the heights of less than 5mm line without losing the text in the line.  I went up to line on "exactly".  As soon as I try to reduce the height of the text disappears, but there is plenty of space above and below the text.   Hoping someone can help.

• Rows in the table LT until merger of all workspaces

  Database 11.2.0.4

  In our environment, we ran a few important updates in the workspaces and then merged these live workspaces.  Up to 25% of the data has been updated in those workspaces.  When these update batch workspaces have been created, previous workspaces exist who are not yet ready for the merger.

  I noticed that the underlying tables of the LT now have about 25% more lines than the live view.  We have now discovered that dbms_wm.refreshWorkspace works really poor.  This statement is used to take seconds or minutes to the maximum, but can now take half an hour or more.

  We recorded a support with Oracle request and provided details of the plan to see if we can get some resolution/advice explaining.

  In the meantime, I have a question for the forum help my understanding of the works of the Manager of the workspace.

  In the example below, I have table "wm_test_table", "test_workspace1" and "test_workspace2".  In "test_workspace1", I update all rows in the table - the table LT now has 2 rows for each record.  I merge 'test_workspace1' live and LT still has 2 rows for each record.  The other lines are not removed until "test_workspace2" is merged and removed.

  Is it possible to safely remove the extra lines in LT without waiting until we merged the workspaces that existed before the update batch has been done?  I hope that it will so improve the performance of refreshWorkspace.

  
  

  I thought that something like this can do, but it does not remove the other ranks, is:
  

  execute dbms_wm.PurgeTable(
   table_id => 'test.wm_test_table', 
   archive_table => null, 
   where_clause => 'id not in (select id from test.wm_test_table)', 
   instant=>null, 
   workspace => 'LIVE', 
   purgeAfter => false);
  

  This question is similar to

  Lines left in the table LT after removal of the direct workspace and the removal of all workspaces

  and

  How to delete soft deleted records?

  but I'm still not sure.

  Thank you

  Hello

  This behavior is expected and it is due to the test_workspace2 workspace.  A compression operation will not allow compressed range to include a backup implicit point that is created for a child workspace.  This is done to preserve the integrity of this workspace.  The initial 1000 lines are all lines that are visible from test_workspace2.  Removal of these lines would leave test_workspace2 will 0 lines in there.  Lines 1000 updates are the lines that do not appear on LIVE.  So, given that the two sets of lines are needed, none of the lines can be deleted physically.  A compression operation will never change the view of data for any workspace.  It only removes the unnecessary records.  The two options in order to be able to compress these lines is to either delete (as you did) or refresh test_workspace2.  The refresh operation would move the implicit savepoint for the workspace to a version that isn't after all 2000 lines in the table _LT and allow the dressing to remove first half of them because they are no longer needed by any child workspace.

  With respect to the performance of RefreshWorkspace, I would need to see a trace of the transaction file.  But who should rather get through the SR you filed.

  Kind regards

• LOV in richeTableau resets the value after the deletion of rows from the table

  Hello. I'm on 11g R2

  I have a table with columns in the box and a button in the toolbar that removes the lines checked

  I have build it based on the following article in her string code

  http://www.Oracle.com/technetwork/developer-tools/ADF/learnmore/index-101235.html

  
  

  When I run the "delete" button I execute the following code (taken as is article)

  
  

  public void deleteSelectedRows() {}

  create a second line, the value do not affect all lines

  used in ADF

  Set of rows duplicateRowSet = this.createRowSet ("duplicateRowSet");

  first row to avoid "the attempt to access the value of lines."

  exception line was dead.

  duplicateRowSet.first ();

  retrieve the current row of the table for after

  re-running the VO

  Line currentRow = this.getCurrentRow ();

  Boolean currentRowDeleted = false;

  get all rows that have the transoent attribute

  "MarkForDelete' set to true

  Row [] rowsToDelete =

  duplicateRowSet.getFilteredRows ("MarkedForDelete", true);

  If (rowsToDelete.length > 0) {}

  run only throizgh this code, if there is something to

  delete

  for (line rw: rowsToDelete) {}

  If the row is marked as the current in VO, ts value

  Boolean flag

  If (rw.getKey () .equals (currentRow.getKey ())) {}

  currentRowDeleted = true;

  }

  remove the line - do not yet commit

  RW. Remove();

  }

  rerun VO

  this.executeQuery ();

  reset the current line if it has not been removed

  If (! currentRowDeleted) {}

  this.setCurrentRow (currentRow);

  }

  duplicateRowSet.closeRowSet ();

  }

  }

  "MarkedForDelete" is a transient attribute used to mark the line delete

  The lines are removed very well.

  The problem is with lines that I do not delete.

  For example I LOV column. I chose the value LOV in a few lines, and after that choose to delete several lines (not the same lines where I modified the LOV) but some other lines.

  After I click "delete", the lines that I marked to remove deleted indeed, but the value of the LOV in other rows (I have not scored for delete) are disabled.

  How to preserve value LOV so it will remain also after I deleted some lines?

  P.S. I've tried autosubmit = "true" - it did not help

  It is expected because I see that you rerun the query.

  Once you re - run, it retrieves from the database again. Thus, your values are lost because they are not posted.

  I don't think that run query is necessary, try to have a programmatic part trigger on the table after you remove all of the lines.

  Thank you

• all rows in the table are not eligible for the specified partition

  P2 Partition Exchange with XYZ Table

  ERROR on line 2:
  ORA-14099: all rows in the table are not eligible for the specified partition
  
  The exchange partition works fine for the first time. However, if we try to swap the 2nd partition it gives the error.
  How to solve this error?
  How can I find the lines which are not qualified for a specific part. is there a query to find out the same thing?

  >
  Well, exchange of syntax and logic is not clearly as it should (IMHO). There is no element of syntax that tells Oracle we want to Exchange partition data in a table that is not partitioned or not partitioned into partition table data.
  >
  What? Not sure where you got that but maybe it was before you had first cup of coffee? ;)

  An "Exchange", it's just that; an Exchange. Partition data end up in the non-partitioned table and vice versa. It is meaningless and totally obsolete if "we want Exchange partition data in a table that is not partitioned or not partitioned into partition table data".
  >
  It was decided by Oracle not partitioned table control. If the non-partitioned table is empty, it means you want to Exchange data partition in a non-partitioned table. And if not partitioned table is not empty, it means you want to Exchange data in the table that is not partitioned into partition.
  >
  There is no decision to make. The segments are swapped. Oracle doesn't check, know or even care if one or the other or both segments are empty. 'Control' which is carried out (by default except if NO CONTROL is used) only consists of ensuring all the data in the segment intended for the partition belongs to this partition.

  It is what gives the example of John. This can NEVER work if table1 is empty unless p1 is empty at the beginning:
  1 Exchange p1 with table1
  2 Exchange p2 with table1

  As John explains, assuming that no other operations are trying to put the data from p1 P2 which is not possible if p1 actually contains data.

  You can save it for next April 1!

• Deletion of rows in a table while the filter condition is in another table

  Hi all
  
  I am facing a problem of deletion of a row in a table where the condition is in the other table. To ealaborate the scenario further Let's say I have two tables T1 (the transactions table) and T2 (Master Table). I want to delete a record in the table T1 by checking conditions lies in table T2.

  THE top. TID = TP. TID
  WHERE at the top. DEAL_SITE_ID = inputparameter1
  AND (TP. SEGMENT <>inputparameter2 OR tp.segment is not null));
  
  Here the record is deleted in the two tables, but I don't want to delete the data in my table master i.e table T2.
  
  Any help would be much appreciated. Thanks in advance.

• Why a whole page of rows in the table is duplicate in FrameMaker 10?

  I have a long table in one of my chapters in FrameMaker 10. The table is seven pages long, but a whole page of dollars of rows in the table is duplicated, if the table really should only be six pages long. The first four pages look like this:

  Page 1: Lines 1-7

  Page 2: Lines 8-16

  Page 3: Lines 8-16

  Page 4: Lines 17-28

  Headers and footers are completely unaffected. All the markers from index in the rows of the table are also doubled, so all of the Page 3 index markers are also appearing in the IX file. I've combed through the file on unresolved references, but I can't find. Also, if I insert a blank line in Page 2, all lines is duplicated is no longer. If I insist on the entire table, Page 2 does not seem to be highlighted. I can't select or change anything on the Page 2.

  I'm absolutely baffled why this is happening. A glimpse of what is causing this rowset ghosts to appear?

  Some ideas to play with:

  • Did you wash MIF file to clean small codes that may have been imported?
  • Have you checked the duplicate lines to check that they are defined in the body and not header?

• Display the option button if the number of rows in the table is equal to 1

  I'm having issues there buy maybe a simple script out there.

  I have a table which can have up to four lines. If the table contains only one row, an option button can be clicked to change the format/entry of cells in this row. I have to hide this box of a user option, if they added more of a line to the table and make it available again if they reduce the number of lines to one.

  I have everything else works well (radio buttons change line format, add/delete rows in the table using buttons, number of rows in the first column)

  Anyone have any ideas?

  See you soon

  Bobby

  You can place it in the code that adds more lines when running... If you have questions send the fomr to [email protected] so I can check it out...

• Problem with the removal of the first row of the table

  Hi all

  I have a problem with my forms with tables where I have buttons to add or remove rows from the table. Adding the lines works fine but deleting lines has a problem when deleting the first row. Example: Here is a table with two rows where column 1 has the add and remove buttons and column 2 user imput that looks like this:

  Column 1	Column 2
  Add and remove buttons here	rank 1
  Add and remove buttons here	rank 2
  Add and remove buttons here	rank 3

  If the user deletes line 2 the table looks like which is correct:

  Column 1	Column 2
  Add and remove buttons here	rank 1
  Add and remove buttons here	rank 3

  If the user deletes line 1 then the table looks like which is false since the ranks 2 and 3 should be left:

  Column 1	Column 2
  Add and remove buttons here	rank 1
  Add and remove buttons here	rank 3

  The code is pretty simple:

  Table3.row2.instanceManager.addInstance (1); for the click event of the button Add line

  Table3.row2.instanceManager.removeInstance (1); for the click event of the button Delete line

  What I am doing wrong?

  Thanks in advance!

  The expression will be based on your structure... done .This refers to the current object, parent refers to the container parent of this object and index is the index of this object. So watching your hierarchy and from the key, you will need this.parent to join the line subform is it in (usually it is th esubform that repeats). If it's in a subform, you will need to add another parent. Continue on this road until you get to the repeating subform and then ask its index. Your expression might look like this.parent.parent.parent.index. Using this.index, you find the instance of the button object and there are just people and that's why you always get 0.

  Make sense?

  BTW your form is attached not... so I can't check what you should put it.

• Game max fixed the number of rows in a table

  Hi all
  
  I created a table that should contain only one line and avoid the possibility to add other lines to it, I used the following:
  

  CREATE TABLE <table_name> (
      <field_1> <field_type> unique,
      ...
      <field_2> <field_type>
      CONSTRAINT <field_1_ck> CHECK (<field_1> = <value>) 
  );

  It works, but it seems a bit heavy for me... Is there a better way to define a fixed/maximum number of rows in a table?

• Error when inserting rows into a table

  Hello
  
  We have recently migrated to 9i and 10g. We have a scheduled task on our database who first removes all rows from a table and then inserts them back by selecting the lines of 5 tables. This table has a composite primary key based on 6 columns in it. In 9i, when I try to insert rows in the table after you remove all of the lines, I am able to insert the data successfully. However, in 10g, when I try to do the same operation, it fails with error ORA:
  
  ORA-00001: unique constraint violated
  
  The same query that works perfectly in 9i fails in 10g
  
  If anyone has some ideas on how to solve the same, kindly let me know.
  
  Thanks in advance.

  Hai
  To display a check box my table on page jspx, I created a transitional attribute, the salt and the type select as Boolean.Then when I drag and drop my page jspx viewObject. The table cantain id, name, designation, salary, salt
  Then I deleted the link in the column of salt and drop a checkbox select Boolean to this column. Then in the property inspector, I bind the value # {row.sel} for box...
  Suppose that there are 5 lines in my table... I checked only 3 of them. When I pressed a button, the corresponding to the id must be extracted and checked lines in the table and I want to show more details corresponding to this id of in another table in the jspx page. I use jdev 11

  Hello

  So if I find correct this time, you do not want to select the lines by clicking on the row in the table but rather by selecting the check box that you created. Fix? Sorry, previous confusion is because of me "thinking in Trinidad. Anyway, you can then set the rowSelection of the table as zero, as you select the line in this way. Try the code below.

  public String doSomething() {
      List rows = getAllRows(getTable1());
      for (Row row : rows) {
          if ((Boolean)row.getAttribute("sel")) {   // Check if it's true which (should) indicate the checkbox as being selected
              System.out.println(row.getAttribute("id"));   // Your selected id based on the checkbox you selected.
          }
      }
  }
  
  public List getAllRows(RichTable table) {
      List rowList = new ArrayList();
      Row row = null;
      FacesCtrlHierNodeBinding rwData = null;
      int total = table.getRowCount();
  
      for (int i = 0; i < total; i++)  {
          rwData = (FacesCtrlHierNodeBinding)table.getRowData(i);
          if (rwData != null) {
              row = rwData.getRow();
              rowList.add(row);
          }
      }
  
      return rowList;
  }
  

  A few points to note. The getAllRows method loops through the entire VO. So if you have 10,000 rows, shut up 10,000 times. If you are dealing with large records or who want to optimize the code, you will need to loop through the "displayed" only lines. To do this, you need to change the code.
