• How to hide/show the column in a table

  Hello world
  
  I have a table based on the table "Dept".

  Dept_id
  supervisor_name

  Dept_id is the LOV, and it has value (11, 12,...) (20),
  Here, when the Dept_id value is selected as 20, then the field "supervisor_name" must be posted, for the rest of the values, that it must be hidden.
  How this can be done using Jquery?

• In windows 8 How do you do the column bookmarks 'flexible '? I used to be able to make it narrower.

  Windows 8 How do you do the column bookmarks 'flexible '?

  Sounds that you use the bookmarks Menu button that opens a drop-down list.

  Firefox has two buttons bookmark with a star in the window customize.
  
  A single star button has a drop-marker that opens the bookmarks menu and may appear on the Navigation toolbar or on the bookmarks toolbar if the menu bar is hidden.
  
  The other Star without the drop-marker button opens the bookmarks in the sidebar (view > sidebar > bookmarks).

• How can I calculate the total time in java?

  Hello!
  
  I need to calculate the total time!
  
  For example I start time:
  Format formatter1;
  Date date1 = new Date();
  formatter1 = new SimpleDateFormat("hh:mm:ss");
  Dim startTime = formatter1.format (date1);
  startTime = "14:20:40.
  
  And I have finishing time:
  Format formatter2;
  Date2 date = new Date();
  formatter2 = new SimpleDateFormat("hh:mm:ss");
  String finishTime = formatter2.format (date2);
  finishTime = '08:30:55;
  
  
  
  Also, having calculated manually, I get the total time: '18:10:15.
  
  How can I calculate the total time in java? (Using formatter1 and formatter2 I guess)
  
  What I need is to print 'total 18:10:15 '.
  
  Thank you!

  I did the following, but I think something's wrong here:

  I've defined before: Date date1 = new Date(); Date2 date = new Date();
  And it should be exactly 5 seconds between them.

  I found the delta between date1 and date2:

  Format formatter = new SimpleDateFormat("HH:mm:ss");
  timeInMilliFromStart long = date1.getTime () - date2.getTime ();
  Date date3 = new Date (timeInMilliFromStart);
  String timeInSecFromStart = formatter.format (date3);

  and I still get
  timeInSecFromStart = 02:00:05

  But it should be exactly 00:00:05.

  What is a problem?

  Because, as I said, a Date to measure a moment in time, not a period. So when you have 5000 ms, and you that transform a Date, this means that 5 seconds after the time, which equals 00:00:05.000 01/01/1970 GMT.

  As I said, if you are not currently in GMT, then you must set the DateFormat GMT TZ. Right now, it's to show you the time in your TZ. If you have included the date in your SimpleDateFormat, you would see the 01/01/1970 or 31/12/1969, function that TZ you find.

  Bottom line: you try to use these classes in a sense they are not intended for, and while you can get the results you want for a limited set of entries if you understand how these classes and how to work with it, it is a fragile approach and comes with all sorts of warnings warning.

• How do we calculate the growth of the database?

  I have the situation where I have to calculate the growth of the database. I'm new to this business. We have implemented new indexes on the database of production where it took freespace all that remains. So, we have increased tablespace because we still have a few clues more to compile. Unfortunately, we ran out of space on the server. I asked for more space on the server that is to say 50% of the current database size. Of course, there are other databases on the same server and management wants to know why I need that a lot of space. Now my question is
  
  1. How do we calculate the growth of the database?
  2. How do we know how much table space is necessary for the given index.
  3. while maintaining growth increased from DB in calculating how we predict future growth.
  
  Any help much appreciated. Thank you.

  Hello

  What exactly do you do?

  If you want to display the tables containing these columns, you can query the view data dictionary USER_TAB_COLS (or ALL_TAB_COLS, or, if you have privileges, DBA_TAB_COLS).

  For example:

  SELECT table_name, column_name

  Of user_tab_cols

  WHERE nom_de_colonne IN ('DNAME', 'FNAME', 'FIRST_NAME', 'LAST_NAME', 'LNAME') - or else

  ORDER BY table_name, column_name

• How will I know "the size of a table special VS size of RAM"

  Hi all

  How will I know "the size of a table special VS size of RAM"?

  I should know because I want to understand what join method to use.

  Please correct me if my attempt to catch the truth is crazy.

  Thanks in advance.

  You can get the size of a table of DBA_SEGMENTS.  I'm sure you can get the amount of RAM of other tables of data dictionary as well if you can define precisely what memory segment you are interested in (e.g. CMS?)  PGA?  The amount of physical RAM on the box?  The size of the buffer cache?  The amount of virtual memory available?)

  That being said, comparing the two is not as significant.  You, as a developer, are generally not in the business of choosing a join method.  It's the job of the optimizer.  And the optimizer takes into account a range of data that you have not begun to ask about yet.  The size of the table is not even particularly relevant for calculations - the optimizer the amount of data operations are back, the relative size of the data on each side of the join, the availability of indexes, etc. are all much more important than the raw size of the table (but the raw size of the array is a factor in the assessment of the amount of data that is returned).

• How can I change the OWNER of a table?

  How can I change the OWNER of a table entr2009mm?
  
  Or the OWNER of all TABLES including tablename match the pattern * 2009 *?
  
  Peter

  Hello

  There are different posiibilities, Import/Export can do.

  But, if it is not a too large Table, you can use ETG (from a user with DBA privileges for example).

  Create Table . as select * from .;.

  Then, you must re-create the dependent objects (Index,...) and remove the Table Source.

  If you have a set of Tables, it is preferable to use Export/Import.

  Hope this helps.
  Best regards

• How to not display the column heading in the table view?

  I don't want to display the column header in the table display, how I can make?

  If you use JavaFX 8, you can use the following text in an external style sheet:

  .table-view .column-header-background {
    -fx-pref-height : 0 ;
  }
  

  If you use JavaFX 2.2, the - fx-pref-height attribute is not available in css, so I think that you must resort to a search:

  final Region tableHeader = (Region)table.lookup(".column-header-background");
      tableHeader.setPrefHeight(0);
  

  As always, I am obliged to point out that I don't really like the research. Sometimes, they seem to be the only way, however.
