• How to set a default value in the Import Wizard delimited for the date?

  Hello community,

  I am currently trying to import some files delimited in a SQL table via the Import Wizard (right-click on a Table "import data... ") with delimited as input (.dsv) files.

  In step 4 of the wizard, I put the columns in the Source files for the target of the columns of the Table.

  Now, this is where my problem. Whenever a target column has the format "date", I define the mask of translation you want for each column.

  I would like to define a mask by default so that the same format is always used.

  User interface, it looks like this field also exists:

  

  However I can't put it in the wizard itself, and I'm not able to find the option in the preferences.

  I tried the following preferences (Oracle SQL Developer 4.0.2):

  Preferences-> database->-> all NLS date 3 preferences set to "HH24:MI:SS DD. MM YYYY ".

  Preferences-> Migration-> translators-> Format of Date Source default value "HH24:MI:SS DD. MM YYYY ".

  Preference-> Migration-> data move Options->

  

  But still, I have to type it every time.

  Can someone explain how to set the default value?

  You can not.

  But.

  In the next major release, we seek to:

  • selection of a menu selector common date formats drop-down
  • Save your import settings session and their reloading for later import

  I think you have a good idea, maybe it defaults to MRU. When we start the process of the Beta/early adopter, be sure to check and let us know what you think. For the moment, and what I'm doing, I copy the date format string and paste them in such as required. I'm not a super big fan of having default values in 'automatically' added because it can lead to mistakes, and in this case, data corruption issues.

• How to set a default value for the bar to EXPLORE in Office XP Explorer?

  When I explore my PC Explorer bar to the default left hand blue component with what is called frequent tasks. I ALWAYS click on the folder icon (or view > bar explore > files).

  I would like to open like that by default - is a registry setting or remove this?

  Thank you
  Neal

  1st post!

  Hey Neal.uj,

  Welcome to the forum!

  You can set the default action on a folder to explore instead of to achieve this effect. To do this:

  ·         Click Start

  ·         Click on Control Panel

  ·         Open Folder Options

  ·         Click the File Types tab

  ·         Click the folder

  ·         Click on Advanced

  ·         Click on Explorer

  ·         Click set as default

  ·         Click OK

  ·         Repeat the same process for file

  ·         When you're done, click close

  Hope that helps, I look forward to hearing from you.

• How to find null values in the table

  Hi experts,
  
  my version is oracledb10g:
  
  I am doubted simple.
  
  for example:
  
  create table ex1 (e varchar2 (20));
  
  Insert ex1 (null).
  
  insert into ex1 (e)
  
  number of will be: 2
  
  I can easily find the value "e".
  
  so my question is:
  
  How can I find null values in the table and I want to remove the null values from the table.

  It depends on what you expect. If you issue count (*) you ask Oracle "how many lines there. If you issue a County () you ask Oracle 'how non null values for are there. "

  delete from 
  where  is null;
  

  Ideally you would simply place a NOT NULL constraint on the column in question, thus prohibiting NULL values into the system (assuming that your business needs, it is that the column MUST always have a value).

• How to set a null column in a where clause clause involving a statement box

  In oracle APEX, I a (selection list) element called: P32_STATUS. It contains two values of interest (for this discussion): 'Available' and 'checked '. In my report, I have a column called vc_status that contains two values: "Checkbox" and NULL. In my application I want to use a case statement in my where clause similar to the lines of

  where

  .

  .

  .

  AND (vc_status = CASE WHEN: P32_STATUS = "Checkbox" THEN : P32_STATUS )

  WHEN : P32_STATUS = 'Available' THEN NULL END)

  The 'box' filtering works but the filtering to try to vc_status the NULL value does not work. Can someone help me? Thank you!

  (P.S. My intuition says that there because I can not put vc_status = NULL, but I must say that vc_status IS NULL... However, I don't know how to do execution IS ZERO inside a CASE statement)

  Hello

  Your intuition is right...

  In Oracle NULL is a bit special:

  NULL = NULL is false

  NULL <> NULL is false

  Thus, instead of the parameter a NULL value in the CASE WHERE there is just set a value on the other side:

  NVL (vc_statut, 'Available') =: P32_STATUS

  That's all! Simple, clean and functional

• Evolution of the null value in the data view tab

  Is it possible to update a null value in the data view table tab? When I delete the value, it creates a sql such as
  
  Update table set column is where id = 1;.
  
  How to fill a null from the data tab?

  I met (and displayed) on this same problem some time. (See forum article "invalid column index: getValidColumnIndex" in SQL Developer 1.5.4 . "") Jim Smith pointed out it seems to be the reappearance of an old bug.

  There are some alternatives. One is "do-it-yourself" in the SQL or SQL worksheet * more. (I.e., "UPDATE someTable SET someColumn = NOTHING WHERE tablePKColumn = pkValue;". The other is to use an earlier version of SQL Developer for that in the view of table data. (I still have Developer SQL 1.5.1 installed just for this reason).

  I hope this helps.

• How to use setViewportBounds (Bounds value) to the ScrollPane?

  How to use setViewportBounds (Bounds value) to the ScrollPane? This method is, visually, what for? I tried to put a specific Bounds.minY to have a precise scrolling in the axis Y in vain. I use the setVvalue() method to scroll, but it is not convenient to exactly locate a position in the coordinates of the node content listed in the scroll pane.

  The viewportBounds are the limits of the viewport (i.e., the visible part of the content) in the scrolling pane itself, if I understand correctly. The way to access programmatically is by setting the vValue property.

  I have not tried, but if you do something like

  scrollPane.setVmin(0);
  DoubleBinding vmax = new DoubleBinding() {
       { super.bind(scrollPane.viewportBounds(), content.heightProperty()); }
       @Override
       public double computeValue() {
          return content.getHeight() - scrollPane.getViewportBounds().getHeight() ;
       }
  };
  scrollPane.vmaxProperty().bind(vmax);
  

  to configure your component to scroll, then you can call setVvalue (...) and just pass a location of coordinates for your content node. This assumes that your content node is a region or a control; you will have to perhaps a little logic in the method computeValue() to deal with the cases where the display window is greater than the additional content.

• Need to null values with the values of filling the date before weekend/holidays

  What could I do?

  Hello

  You can use the analytic LAST_VALUE function to get the last day of work before each date into your table. It will be the same as the current day for every day of work.
  Do it a self-join to combine each current line (c) with the last day of work (l):

  WITH     got_last_work_day     AS
  (
       SELECT     dt, type, rate
       ,     LAST_VALUE ( CASE
                      WHEN  type  IS NOT NULL
                      THEN  dt
                     END
                     IGNORE NULLS
                    ) OVER (ORDER BY dt)     AS last_work_day
       FROM     table_x
  )
  SELECT       c.dt, l.type, l.rate
  FROM       got_last_work_day     c
  JOIN       got_last_work_day     l  ON       (    c.dt          = l.dt
                           AND  c.type          = l.type
                           )
                         OR     (    c.last_work_day     = l.dt
                           AND  c.type          IS NULL
                           )
  ORDER BY  c.dt
  ,       l.type
  ;
  

  Among other things, I guess that the type is NULL if (and only if) the line represents a holiday or weekend, and that the combination (dt, type) is uniuqe.
