Combine data deletion of nulls

• correct handling of foreign keys in unique constraints for operations ON DELETE SET NULL

  During my troubleshooting at a client site, I came across an interesting setup where I would like to ask your opinion.

  
  Consider two tables ADTB and TBLB.

  ADTB:

  INT COLA1

  COLA2 INT

  TBLB:

  COLB1 INT

  COLA2 is COLB1 as a foreign key ON DELETE SET NULL value.

  COLA1 and COLA2 are combined into a UNIQUE for the BATTERY constraint.

  I have two records of TBLB:

  (1)

  (2)

  and two DRUM recordings:

  (1, 1)

  (2, 2)

  so far, all the constraints are valid.

  During my research, I learned that I can not put COLA2 null in ADTB for two lines at the same time:

  TBLA UPDATE set COLA2 = NULL where COLA1 = 1;

  -> OK

  TBLA UPDATE set COLA2 = NULL where COLA1 = 2;

  -> VIOLATED UNIQUE CONSTRAINT

  Unfortunately, it's something my application needs, anyway. In order to get this resolved, but I try to understand, what would happen if I:

  REMOVE THE TBLB;

  ?

  It should set COLA2 in ADTB "Null" on the two lines, which is not allowed due to the UNIQUE CONSTRAINT.

  Can someone shed light on this issue? Thank you.

  Unfortunately, as you say, you can't not NULL values in such a unique constraint.  It would be the same as if you had a composite primary key and try to allow one of the columns will be null in several rows with the same value in the other column.  NULL is treated as an "unknown" value, it is possible that it could be the same value (it may or may not be, but Oracle does not know), so it must assume that it might be and that's why treat it as if there is the potential for a duplicate... so it's not unique.

  In short, do not allow null values in your unique constraints.

  The default is in the drawing, not in the way that Oracle is the treatment.  Fix the design if you do not have NULL values.

  In terms of relational database design, it seems that you are trying to transform the 1:M relations M:M relations, and which requires an intermediate table if you have M:1 and 1:M between 3 tables instead.

• Create the query by combining data from DBSS_Data_Model and HostModel

  Hello

  I am trying to create a dashboard with the host server list and instances of SQL Server running on the host.

  And I am interested in creating a query by combining data model of data in SQL Server (DBSS_Data_Model) and the host (Hosts) data model, say: which connects DBSS_SQL_Server_Host and host.

  I wonder if there is way to do it?

  Thank you

  Mark

  Something like this function should work:

  def physicalHost = nullqueryStatement = server.QueryService.createStatement("(Host where name = '$hostName')")result = server.QueryService.executeStatement(queryStatement)objs=result.getTopologyObjects()
  
  if (objs != null && objs.size() > 0) {     physicalHost = objs.get(0)}return physicalHost
  

  When the input parameter "hostName" is DBSS_SQL_Server_Host.physical_host_name

  Kind regards

• Date range prompt--Null default value

  Hello

  It is a follow-up on post Date invites default NULL

  I have a similar case but using database directly request the report and have implemented a variable presentation with two date ranges. I want to leave the default value of the date white values in the dash prompt, but have the ability to enter values in the other guests and ignore the date of the application

  I have 4 variables of presentation being placed in the SQL query, two of which are the date ranges (between)

  I use OBIEE 10.3.1.4, is there a workaround to run the report using the other prompt values and ignoring the date values null?

  Hello

  Keep your 1900 filter in report itself and no default value chosen at the prompt. If this value is not visible in the dashboard and it will fly too when the user selects a value from the command prompt.

• All the members (but 1) are removed from the entity dimension in planning and deployed to essbase. -What are the data deleted in essbase so? / The data can be restored by restoring the entity dimension?

  All the members (but 1) are removed from the entity dimension in planning and deployed to essbase.

  -What are the data deleted in essbase so?

  The data can be restored by restoring the entity dimension? EPMA the entity dimension is still in tact.

  It is unclear what exectly arrived, but looks like a change was made in the dimension entity planning (not EPMA) and then deployed (successfully).

  In essbase, we see that the entity dimension has only one member left for the appropriate plan types, as in the planning.

  If you remove members and then push that yes the essbase data is deleted, if you need back then you will need to go back to your restore process.

  See you soon

• Deletion of nulls

  Hello
  
  To maintain the integrity of Refrential, we have included nulls for some of the columns in the database, but when I use the columns of the guests at his watch these nulls as well. For now, I got deletion of nulls SQL results. I was wondering is there all work around for the removal of null values instead of using filter conditions and writing sql for you ask?
  
  Thank you
  Phani.

  If do not want these nulls frontend...
  You can restrict their in LTS... to the RPD content filtering

  go to this particular logical dimension table where this column comes from form and then content tab.
  you find where clause parameters it (called content filtering) then using button of eclipse, you can apply this filter...:

• Exclude a combined field data field empty (null)

  Hello

  I have a simple (I hope) question I'm stuck...

  At one point in our form, we ask for the cell at home and work numbers. These are optional.

  later we want to re - use the phone contact information provided earlier

  the second place (call it field X in our example) where these data are using I was going to just go something like

  this.rawValue = A.rawValue + rawValue. b + c. rawValue;

  where A, B, C are cell phone, work fields and home earlier and that = X.

  But this happen inserted fields NULL if the user leaves the initial blank (for example is they only have a cell and thus leave the House empty).

  So I would test to see if the field is null, before it can be used

  can anyone suggest a code that allows the following logic

  x.rawValue = A.rawValue + B.rawValue + C.rawValue SO LONG AS A, B AND C all THE PHONE NUMBERS IN

  otherwise if ONLY A AND B have given then x.rawValue = A.rawValue + B.rawValue

  otherwise if ONLY A and C

  or only has

  etc.

  then the correspondent only filled fields of x rawvalue-

  I have experienced various syntax but can not get it quite right - someone ' can someone help or does have a sample of something similar that I can mold my needs?

  Thanks in advance

  var strAValue, strBValue, strCValue

  Get a value

  If (A.rawValue == null |) A.rawValue is"")

  strAValue = "";

  on the other

  strAValue = A.rawValue;

  Get the value B

  If (B.rawValue == null |) B.rawValue is"")

  strBValue = "";

  on the other

  strBValue = B.rawValue;

  Get the value of C

  If (C.rawValue == null |) C.rawValue is"")

  strCValue = "";

  on the other

  strCValue = C.rawValue;

  X.rawValue = strAValue + strBValue + strCValue;

• Enterprise remote data deletion

  Hello everyone, I'm still new in the it field. I got a year ago, with a degree of general partners of a school local tech. I'm currently studying for my Windows 8 cert. I read an e-book and came across remote deletion of corporate data. I was talking to a colleague who is interested and wants to learn more. I'm doing some research on this subject. What I understand users can use their smartphone or laptop and connect to the network/domain to access the data. If the laptop or the phone goes missing, we can use this tool to remotely wipe the device or temporarily to make the data on the device unusable. I understand that RBDR is using Exchange ActiveSync to management along with Active Directory for authentication. Many of our customers use Office 365, so everything is done in the cloud. I have done a lot of research on Google but have not found much RBDR except that it is. Can someone help me understand this tool or point me to a good article that explains a bit more in depth about how this works.

  Any help is very appreciated. I'd like to understand what this tool and how it works.

  Thank you.

• Trigger to insert data on the null columns

  Hi all

  How can I create triggers to insert data into a column null, this column is a Varchar2.

  Thanks in advance.

  Start

  : new. MYCOLUMN: = nvl(:new.) MYCOLUMN, 'A value');

  end;

• 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])
  }
