• How to deal with Menu select when there are NULL or a value with SQL

  I have a Menu(:P_55X) SELECT with:

  "NULL VALUE DISPLAY" = NULL

  'NULL RETURN VALUE' = NULL

  The graphical query is as follows.

  
  

  SELECT NULL LINK,
  START_DATE "FOR_MONTH",
  ROUND(AVG("SLA"),3) "SLA_UPTIME"
  from SLA_TIMES_ZABBIX
  LEFT JOIN (SELECT DISTINCT NODE_NAME,OS_TYPE from CMS.CMS_NODE_OS where remove_dt is NULL) OSNODE on LOWER(SLA_TIMES_ZABBIX.NODE_NAME)=LOWER(OSNODE.NODE_NAME)
  where OS_TYPE=:P55_X group by START_DATE order by START_DATE ASC;
  

  How can I accout for the (: P55_X) variable is sometimes NULL and not null sometimes. which means I can't use the '=' when values is null because I need an IS NULL it.

  The column in the database has a value or is set to NULL.

  Thank you

  Robert

  where (OS_TYPE = :P55_X OR (:P55_X IS NULL and OS_TYPE IS NULL))
  

• Search, select and delete Pages Null?

  While trying to find a way to quickly reduce the size of large PDF files that are read online, I thought I would highlight a keyword on the pages that I need and then delete pages without annotations. I decided to replace step 2 action to search and highlight words with my own script. The script I came up with, (my first) works very well on the 35-page document that I used to develop:

  var pageArray =]

  for (var i = 0; i < this.numPages; i ++)

  {

  Aannots = this.getAnnots (i);

  If (Aannots is nothing)

  {

  pageArray.push (i);

  };

  pageArray.sort ();

  pageArray.reverse ();

  }

  for (var j = 0; j < pageArray.length; j ++)

  {

  this.deletePages (pageArray [j], [j] pageArray)

  }

  but when run on a very grand, 2000 + page doc, it removes some of the pages, then crashes or finishes with:

  «TypeError: invalid argument type.»

  Undefined Doc.deletePages:62:Batch: Exec

  = > Start parameter. » »

  in the console.

  If I continue to run this code in the console, it subsequently deletes all pages not annotated.

  Since the arguments come from the matrix, I print and am surprised that it is not in reverse numerical order, than I expected.

  Could it be the problem?  or one of them?

  Thanks for any help you can give... to 65, I don't know if I'll live long enough to understand this!

  When you remove items from any kind of table, it is always a good idea to loop top from the end of the beginning, because you delete items inside you effectively change the size of the array and this can screw up the next steps in your loop.

  Otherwise, you will need to reverse the order of the table (which your code is trying to do, but it does not work because of how works the sort function). Try this code instead:

  var pageArray=[]
  for (var i = 0; i <  this.numPages; i++) {
      Aannots = this.getAnnots(i);
      if (Aannots == null) {
          pageArray.push(i);
    };
  }
  pageArray.reverse();
  
  for (var j = 0; j < pageArray.length; j++) {
      this.deletePages(pageArray[j],pageArray[j])
  }
  

• From 0 to NULL

  Hi buddies!
  
  I am faced with a situation where I need to convert the values 0 to empty string or NULL.
  
  For example,.
  
  I have a 3 column table Testing
  
  column at the beginning, middle, end
  
  They are of type varchar2 (20) that contains numbers.
  
  If the column had to display 0, I should replace it with NULL.
  
  How can I do that. Please guide me.
  
  Should I provide more details?
  
  Thank you.
  
  Benard

  Use a DECODING

  Thus

  decode(col_1,'0',NULL,col_1)
  

  converts null values for '0', but if the line is not a '0', it returns the actual value.

  Why 3) plan is so bad? (In any case, it's like "UNION ALL" of 1) and 2).

  Thanks in advance,

  We do not know if one of them is 'bad' plans.

  In fact, there is no such thing as a bad plan, one or several inaccurate estimates.

  To determine whether a plan is 'bad', you really see who believes are inaccurate - and which means the time of execution of the execution plans and runtime enforcement measures.

  Please take a look at the notice in the following thread:

  HOW to: Validate a query of SQL statement tuning - model showing

  What happens in the third SQL, is that because you referenced the subquery WITH twice, Oracle decides to materialise it in a temporary table for the reason that it is cheaper that to do the same thing one subquery normally twice - a reasonable approach.

  It is probably more likely that the third query estimates are more accurate than the other two.

• Select list or view Auto text

  Hi guys,.
  
  I'm trying to disable my tabular presentation the Application column . If the data exists, it must be blocked, but if the user clicks the Add button the selection list should appear.

  document.getElementById('f05_000'+i).disabled = true;
  
  $x('f05_000'+i).readOnly = "readonly";
  ......
  
  But when I click on submit button I got error of constraint because the list selection change of value null.
  
  now I'm doing it
  
  Select
  ID,

  v('REQUEST') = "Add" THEN

  But it does not work too. Can you give me some suggestions?
  
  I use Apex 4.1.1
  
  
  Thank you

  After you turn off the value of the selection list, you can't get the value of the selection list. In your case, you can hide the selection list until you create a text element with the value selected in the select list, try the code below in DA

  $('select[name="f05"]').each( function(i) {
  
       var rowSelected= $(this).attr("id").substr(4);
  
          var appSelect= $('#f05_'+rowSelected).attr("id");
  
            //To change the background color for Application column
  
             $x(appSelect).style.background = "#F2F2F5";
  
            //To get the value from "Application" select list and hide it
  
            var fake = $(""+$("#f05_"+rowSelected+ " :selected").text()+"");
            $("#f05_"+rowSelected).before(fake);
            $("#f05_"+rowSelected).hide(); 
  
          }
  );

  and     'R'     = nvl (:PARAM_STATUS, 'R')
  ;
  

  SQL is sufficient for this purpose; you needn't PL/SQL.

  It will probably be more effective to your .NET application so check param_status is 'A', 'R' or NULL first, then branch to one of the 3 most effective query.

  I hope that answers your question.
  If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.
  Explain, using specific examples, how you get these results from these data.
  If the problem involves (for example param_status) parameters that are not in any table, and then after a few differetn sets of parameters and the results you want from the same sample for each game data.
  Always tell what version of Oracle you are using.

• How to write a select statement inside the case operator

  Hi all
  
  I want to write a query that get the result of another table of case operator.
  
  for example
  
  Select a, b, c of the double
  where a = 1
  and b = case when b is null then 'select any value from the other table' any other purpose;
  
  
  Please help me to write this query.
  
  Thank you

  Select a, b, c of the double
  where a = 1
  and b = case when b is null then 'select any value from the other table' any other purpose;

  Guilty plea

  Select a, b, c from tableA a
  where a.a = 1
  and a.b = (select decode (a.b, null, (select 1 from tableB b where rownum = 1), a.b) double)

• for j in (select one, c (select 1 of the double),) loop... end loop;... error

  declare
  begin
   for cur in (select (select 1 from dual) col from dual)
   loop
    null;
   end loop;
  end;

  TOAD, OK, BUT in the wrong FORM!

  As you may or may not know, the PL/SQL engine forms is not the same as that of the database; Forms is generally a lower version than the database. As for your code block, please try this instead:

  BEGIN
    FOR cur in ( SELECT col1 FROM ( SELECT 1 AS col1 FROM dual) ) LOOP
      NULL;
    END LOOP;
  END;
  

  This form of the loop For cursor to compile in 10.1.2 Forms. The problem was that the Forms PL/SQL engine could not derive your view online column.

  Hope this helps,

• create the table in SELECT (question)

  Hello
  
  In regards to create the table as subquery, I read that:
  
  The data type of column definitions and the NOT NULL constraint are passed to the new table. Note that only the explicit NOT NULL constraint is inherited. The PRIMARY KEY column will not function NOT NULL column null. Any other rule of constraint is not passed to the new table. However, you can add constraints in the column definition.
  
  Can someone explain to me how to do this? Or, how we need to specify the constraints (and also the default values for columns, because it is possible) for the columns in the column definition?
  
  In addition, I do not understand this: the PRIMARY KEY column will not function NOT NULL column zero.
  Can someone give me some small examples regarding these?
  For example, it generates an error:
  

  create table test1 (a, b, c default sysdate) 
  as 
  select 1, 'b' from dual

  Thank you!

  Hello

  When you set a primary key consists of a unique constraint and a constraint not null, but they are both implicit with the primary key. When you create the table because it will copy only the explicitly declared NOT NULL constraints so it isn't look upward than the implicit NOT NULL primary key.

  However, a primary key can reuse existing constraints and indexes instead of declaring new. For example, we can explicitly declare a constraint not null on the column id and then create a primary key. This means that we will now inherit the constraint not null in the ETG, as it has been explicitly declared and is a constraint separate in there own right that has been 'borrowed' by the pk constraint.

  Regarding the definition of the default values, you must always specify the column in the select, but doing so means follow you the semantics of a default in a standard INSERT statement, i.e. you specified the column, you must provide a value, in which case even if the value is null, the default value will not be used. However, the new inserted rows where the column with the default value is not specified will revert to the default.

• Insert data from a particular region.

  I have two region report...
  
  I use apex item to insert data into a table. When I try to insert the data from the 2nd report region, region 1 data get insert instead of the 2nd region report data.
  
  How to distinguish the point of apex from one region to another region?
  
  This is my 2nd region (doc) report

  insert into doc values(apex_application.g_f02(i),apex_application.g_f03(i),apex_application.g_f04(i));

  How to solve this problem?
  
  SKUD.

  Hello

  Make sure that the columns of report 2 region should not have same value p_idx.
  Example-

  Report 1 query
  
  select apex_item.text(1 , null);
  
  Report 2 query
  
  select apex_item.text(1, null);
  

  In the example above if you see the both the query have same p_idx value in 1...

  In this case, if you try to save the data in the second report it will save the data in the first report.

  To avoid this, you must make sure that the p_idx value is different... This is... If you the first query has five columns with p_idx the value 1, 2, 3, 4, 5... so for next report make sure that the value of p_idx must be greater than 5... for example... 6, 7, etc.

  Kind regards

• display of the values of selected option buttons

  Hello
  
  It is an application that would allow users to go through a step-by-step process to build their product, in this case, it's ice cream.
  
  
  Description:
  
  There are six option buttons, four belonging to a radiobuttongroup and two others belonging to an another radiobuttongroup. In addition, there is a mx:TextArea (including the editable value false).
  
  This Panel will most likely go into a mx:ViewStack as a "first step" in the process of personalization of the ice cream. The selection of a radiobutton to every radiobuttongroup must be required to move forward (go to the next "step", as in the Panel following in the ViewStack).
  
  Problem:
  
  Allowing the user to select an item in each of the two radiobuttongroups and write values of these two selected radiobutton [such as specified by the value of the radiobutton = property 'radioButtonValue'] to the mx:TextArea, on different lines.
  
  I have been moderately successful in trying to do it, but I didn't know how to write two values in the same text box
  without crushing them each other.
  
  Misc.
  
  At first, I tried something to the effect of: ( changed from the 2 flex components Explorer)
  
  < mx:Script >
  <! [CDATA]
  
  Import mx.events.ItemClickEvent;
  
  Event handler function to display the selected button
  in a text box.
  private void handleConeType(event:ItemClickEvent):void
  {
  If (event.currentTarget.selectedValue is "sugarCone")
  {
  iceConeTextBox.text = "Sugar cône";
  }
  on the other
  {
  If (event.currentTarget.selectedValue is "waferCone")
  {
  iceConeTextbox.text = 'Wafer cone. "
  }
  }
  }
  }
  []] >
  < / mx:Script >
  Quite exaggerated to get something to work, I know. It was not very effective, and I sincerely hope that there are better ways to do this.
  
  I would like if possible avoid using two mx:textareas.
  
  Example of
  
  Here is a link to better describe what I'm talking about (Note: View Source is enabled).
  
  ConeChooser Application
  
  
  Thank you!

  You can access the selected radio button value the id of Group of radio button groups, you don't need to check each radio button individually. Then coneType.selectedValue will give you the value of a button radio is selected in the group, and the coneType.selection.label will give you the label of the currently selected option button or null if none is selected.

  Try this code:

  
  http://www.Adobe.com/2006/mxml '.
  Width = "100%" height = "100%" layout = "absolute" >
  

  private function updateText (): void {}
  var totalSelected:uint = 0;
  var cone: String = "";
  var size: String = "";
  If (coneType.selectedValue! = null) {}
  Cone = coneType.selection.label;
  totalSelected ++;
  }
  If (coneSize.selectedValue! = null) {}
  size = coneSize.selection.label;
  totalSelected ++;
  }
  iceConeTextBox.text = '\r', cone + size;
  If (totalSelected == 2) {}
  next_btn.enabled = true; to go to the next view in the viewstack
  }
  }

• How to select the default printer

  Hi all
  
  Here's the scenario:

  Report Version:2.5.5.2.7 (I know really old :) )
  Form Version: 4.5.7.1.6
  OS: Windows Xp with SP2

  Whenever the user clicks on the button PRINT an invoice form, the report should
  print directly without showing no preview (is a different button for preview).
  I choose the number of copies that must be printed in a table in DB.
  Make a list of parameter (for destype, desname, copies, etc.) and call the report. (RUN_PRODUCT)
  It is if I take the name of the printer to DB something like \\machine_name\printer_name and assign it to desname, it works very well.
  However, instead of picking it from the DB, I want to know if I can get the default name of the printer directly from the machine where the report is running.
  
  Reason: If a printer goes wrong and the user wants to print to a different printer, I don't have to keep on changing the values in the comic book.
  
  All entries/tracks will be appreciatted.
  
  Thank you
  Bobin
  
  P.S : I bestow points like cookies ;)

  Hi Buqa,
  Nice to see you in the forum reports ;) if I saw you in the forum of pl/sql.

  In fact if you want to print to the default printer. Then just the DESTYPE PRINTER setting there. The report will go directly to the default printer and if you mention the DESNAME then it will go to the selected printer you. I mean if the printer selected, you'll pass null, then you can just move the DESTYPE then report will go directly to the default printer.

  By NOTHING, I mean not to pass the parameter in the case of the DEFAULT PRINTER.
