• VMFS does not see the measuring devices?

  I ran into a problem with my ESX 4 deployment.  Recently, I expanded the size of a LUN in my SAN so that I could extend the data store associated with this volume.  The data store recognizes the new 300 GB size (image vmfs_prop), however, I'm not presented with options for a measuring device when I try to 'increase the ability to data store' (image vmfs_increase).  I've also updated the filter of vmfs in options advanced thinking that LUN was already associated with the data store and may have been filtered (image vmfs_filter).  Any advice?

  

  

  

  What I meant with "connect directly to the host ESX (i)" has been to connect by using the vSphere Client. Generally, you don't need to use the command line. Have you tried that before the more command line data store? It does not work?

• where clause to see if they contain the null value

  So I've finalized my function but now am having some problems:
  
  the bl field (or the v_bl parameter) has null values in it. When I run the function using the "Select FH ('ACCESS', NULL, 8675309') From dual; I get a NULL return value because it uses the variable to compare with q.bl and you can not have q.bl = null in a Where clause.
  
  The main problem is when the parameters are passed, a line can have the same prob and site, but the bl might be different as null, which would give a different lname.
  
  
  In where clause I need to have something that will compare the parameter with the bl field. Sometimes it's null sometimes is not, but we need to find the line concerned. I made the "BOLD" in the question police
  
  Here are two possible lines in the data
  prob bl site lname
  ACCESS Smith 8675309 (null)
  54321 8675309 Johnson ACCESS
  
  so in theory, if the function is called with the parameters FH ('ACCESS', NULL, 8675306')
  He would return the lname: Smith
  
  and conversely FH ("ACCESS", "54321 ', 8675309") would return Johnson
  
  Here's the function
  
  create or replace
  Function FH
  (v_prob IN varchar2, v_bl IN varchar2, v_site IN varchar2)
  RETURN varchar2
  AS
  v_lname varchar2 (16);
  
  BEGIN
  
  S.Lname SELECT INTO v_lname
  Of
  request q
  JOIN THE
  s response
  On
  (q.order = s.order)
  
  WHERE
  q.BL = v_bl AND - where it is
  q.site = v_site AND
  q.prob = v_prob AND
  s.Lname IS NOT NULL;
  
  RETURN v_lname;
  END;
  
  
  
  -When I run the FH ('ACCESS', NULL,' 86753) function, it returns an empty value and not the family name

  Matches the NULL value
  (1) either you have to say-> q.bl IS NULL
  OR
  (2) WHERE the NVL (q.bl-99) = NVL (v_bl-99) - this will be true if q.bl and v_bl both are NULL
  NULL = NULL evaluates to TRUE, so you use NVL

• How to convert the Null value to 0 after the outer join?

  Hello guys
  
  My requirement is in fact 2 of outer join tables (that's how), and I got the outer join works very well, so in my report, I have values null of measures in another table of facts as a result of the outer join...
  
  Is there a way I can convert these nulls to 0?
  
  I realized that the null value is not stored in the table, it is just following the outer join because the NULL do not match records in other... So by default, I'm expected to get NULL values...
  
  Is there way to present these nulls to 0?
  
  Thanks a lot for your advice

  In response, the syntax will be:

  IFNULL (, 0)

• NULL values for some elements of the XML reading tree

  I am confirming that I interpret correctly all the elements of a custom data XML structure defined by my application (the schema is completely under my control).  Some of the elements in my XML tree are read as NULL values, even if similar items are readind as expected.  I have checked some obvious things like misspelling the names of keys, but have not yet find the problem.  Anyone who has debugged similar questions - what else could cause this?

  Example XML:

  
      1.0.0.0
      1000
      MyAppsName
      
          
              1000
              userDefined
              StructName
          
      
  
  

  And extracted C++ w/comments at the end of each line about what I see (DataManager is my class of CRUD operations):

  In DataManager.hpp:

  QVariant mCustomDataStructsTopLevel;
  QVariantMap mCustomDataStructsTopLevelMap;
  

  In DataManager.cpp:

  mCustomDataStructsTopLevel = mXda.load(Utils::dataFilePath(customDataStructsFileName));  // XmlDataAccess; verified loading w/no errors
  mCustomDataStructsTopLevelMap = mCustomDataStructsTopLevel.toMap();
  
  qDebug() << "appName element value: " << mCustomDataStructsTopLevelMap["appName"]; // Outputs "MyAppsName" as expected
  qDebug() << "lastId element value: " << mCustomDataStructsTopLevelMap["lastId"]; // Outputs null (specifically: QVariant(, ) ) - this is NOT expected
  qDebug() << "appVersion element value: " << mCustomDataStructsTopLevelMap["appVersion"]; // Outputs null (specifically: QVariant(QString, "") )  - this is NOT expected
  

  OK, I got the feeling (and actually hoped) it was a silly mistake of face-palm on my part (compared to a problem of BB10 who had little chance of getting fixed).

  The problem is that I copy the structure of custom data from Starter to my Active dir to my data directory to first install but do not crush him on subsequent launches, as the copy in the data directory is what the user changes and relies on.  I was not a delete and reinstall on each of my iterations, so I wasn't really loading the modified versions of my XML I wanted--just, I was getting a day old stale version which was actually for the items I didn't expect NULL values for nulls.  DOH!

• PersistentStore.getPersistentObject returns the null value?

  I use a random key to retrieve a shape of the object PersistentStore

  persist is PersistentStore.getPersistentObject (KEY);.

  Works fine on the Simulator (OS 5), when I take the code signed to the device (BB OS 5.0 Bold 8900)

  For some reason, it returns null, without exception. Thereafter any API I inoke on PersistentStore / persist returns null without exception persist even when the null value.

  I don't know if it's one thing to eclipse debugger, but even if the debugger shows that objects are null. Controls null applied in the code seems to fail, what does code see these objects as non-null. Pheww! How is it possible.

  In this code still shows up as null, then safetyTable and orderedkeys. However, the value null check in the failure code.

  At a later stage in the code, when I try to access orderedkeys are null again! Are struggling with this problem for two days, all the pointers would be very comfortable.

                      persist = PersistentStore.getPersistentObject( KEY );
                      persistOrderedKeys = PersistentStore.getPersistentObject(KEY_ORDERED_KEYS);
                      safetyTable = (Hashtable)persist.getContents();
                      orderedKeys = (Vector)persistOrderedKeys.getContents();
                      if (safetyTable == null)

• How to reset the value of a list of entry of null values

  Hello

  How to reset the value of a list of entry of null values

  Thank you

  AR

  Place this code in your ViewRowImpl (base) class and use it when you need to reset _all attributes applied by LOV

  @Cvele: in fact, this will happen "by design" when you set the attribute which has attached lov to null, so there is no need of additional code.

  See also this blog: binary: prevent the execution of query unwanted in British Colombia ADF when used in Non - UI applications

  My previous answer is more related to this approach:

  DCBindingContainer bindings = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
  DCIteratorBinding iterator = bindings.findIteratorBinding("IteratorName");
  Row r = iterator.getCurrentRow();
  r.setAttribute("SomeAttrib", null);

• display of the output cursor empty with null values

  I have the below procedure of the State where he is shown the output to the client.

  The requirement now is if the select statement does not return a value any with the input given then output parameter should see NULL values instead of no line at all.

  
  One method is to get the number of the select query that is written in "open p_out for." And then write the condition as if count is 0 then null other show data.

  Could you please suggest me any other alternative to this.

  Create or replace procedure test (p_empno in number , p_out out sys_refcursor) is
  
  begin
   open p_out for 
   select e.ename, d.deptname, s.sal , p.addr , v.age

   where e.deptno = d.deptno and d.deptno = s.deptno
   s.sal_id = p.sal_id and p.id = v.id
  and e.empno = p_empno ;

• test for the null value to IN request (null, 'a ', ' b', 'c')

  Hello

  Oracle 10.2.0.4

  I think the following query is incorrect, in my opinion. (there is an index on the collar, but NULL values are ignored?

  SELECT COUNT (*) < table > where col in (null, 'a ', ' b', 'c')

  It works (no errors) and forth fast enough.

  However, I think the correct query would

  SELECT COUNT (*) < table > where IS NULL or neck neck ('a', 'b', 'c')

  It takes a lot of time. As I see it, he performs a table scan for part of the value NULL and use the index for the rest, as the index cannot be used for NULL values.

  I would appreicate an explanation on this matter, particularly why Oracle accepts the first query "where col in (null, 'a ', ' b', 'c')" without any problem.

  Thank you

  A null value is not equal to what whatsoever, not even another null value. This is consistent with the definition of the ANSI. For your first request is not what you think it does, even if it is not syntactically incorrect.

  The second query is correct. If you want to use an index, you must create a bitmap index (which requires Enterprise Edition licenses), because they do not include the values NULL, unlike B * tree index.

  Problem when I view the item hidden, I can see the value of checksum, but the P31_test is always null in load. When I hit refresh page P31_test valid and displays the value.

  The two elements are the value only when the value in session state is null.

  What could be the reason because it does not load even the process is defined as load before region / once per page visit...

  Thanks for your help.

  Okay - not sure then. On a new blank page I can have processes assign a value to the session state from the element and the element will have this value when the page is rendered (at least with this type of source). Work of dynamic actions. As I expect. I don't know what happens next 'unfair '.

  I'll only come back tomorrow, but here are a few tips:

  • create a workspace on apex.oracle.com and upload your page there. Share of the developer credentials and the name of workspace with us. In this way may inspect and do not need to do the back and forth until we reached something special we both lost from view.
  • When the page is loaded and you hit the session in the developer toolbar, what is the State of P31_TEST? Is it worth?
  • try to run the page in debug and see if you can spot something happens with the session state from P31_TEST - maybe you'll come across something

• NULL value in the print result

  I run a SELECT statement on the form below:

  SELECT col1 |' | ' || col2 |' | ' || COL3

  TABLE;

  It gives me the following outprint, which is what I need

  col1 | col2. col3

  VARCHAR2. number | VARCHAR2

  The problem is when col2 returns a NULL value, then I get this:

  VARCHAR2. VARCHAR2

  When what I want is this:

  VARCHAR2. (null) | VARCHAR2

  Is it possible to get my results of the query to print the value NULL (null)?

  I tried the function NVL NVL (col2, 'null'), but it won't work because there is a mismatch on data types. I can get the NULL value, printed by concatenating don't not columns and save results to csv, but that does not give me the formatting that I want.

  You can convert the character number column, and then look for the NVL.

  See below:

  with data as
  (
    select 'col1' col1, 1 col2, 'col3' col3 from dual union all
    select 'col1' col1, null col2, 'col3' col3 from dual
  )
  select col1 || '|' || nvl(to_char(col2), 'null') || '|' || col3

• Styling Null value in the column attributes

  I tend to the attributes of user input placeholder to display things like "Enter blah blah blah". Then I use the attributes of color CSS placeholder the placeholder with a value lighter than the normal entrance to style text. If the placeholder is paler than normal text entry.

  I would like to DISPLAY NULL VALUE text style that I provide to select LOV is in the same color. For a line given in table format placeholders and select LOV NULL DISPLAY VALUES are consistent.

  Someone knows how to do?

  For example, if I had a list of report selection. And I used a NULL DISPLAY VALUE of 'State of entry', I might have a # 444 color when "Enter State" is displayed and a #bbb color when you see "Georgia."

  I tried including the HTML to the NULL VALUE. Put something like a DISPLAY NULL VALUE < span class = "plus-couleur" > </span > state entry. That did not work.

• Return the first line with a non-null value in a column

  Hey there, gurus. Can someone give me a hand with this?
  
  I have a table with six columns: Class_ID, Course_ID, start_date, Last_Name, First_Name, company. When our students take a class and will fill in an evaluation form, they fill in the Class_ID Last_Name First_Name, and Company. The Course_ID and Start_Date are filled automatically based on the Class_ID.
  
  I am trying to generate a report that contains Class_ID, Course_ID and Start_Date, PLUS the value of the first not null in the column of company for a combination given to the three first columns. Here is my SQL that does not quite do the trick:
  
  Select distinct c.class_id, c.course_id, c.start_date, p.company
  class c, person p, student s
  where substr (c.course_id, 1, 3) = "OBI".
  and c.start_date > = SYSDATE-30
  and c.class_id = s.class_id
  and s.pid = p.pid
  order start_date, company, class_id, course_id
  
  At present, if in a given class, a student entered "CCCC" under the name of the company and another entry "Collin Co Comm Coll" and another between "Collin College", I would get three rows of this class when you use the SQL above. I want just one line. I don't really like which company names gets selected - one of them will be great for our needs. I just need to see a line for each class_id and single value that some students entered the area of the company. And I guess I have to say that if no student fills in the name of the company I need to see the value null, because I need to see the line no matter what.
  
  Looks like some sort of funky outer join or a coalesce, but it is beyond my ability to understand.
  
  Now I get this:
  During class 1234 SQL271 Date 22/07/2013 company XYZ Inc.
  Made up of class 1234 SQL271 Date 22/07/2013 company XYZ
  1234 SQL271 Date 22/07/2013 company XYZ, class
  
  What I want:
  Class 1234 SQL271 22/07/2013 Date course XYZ Inc. or one of the other 2
  
  Thanks in advance!

  select c.class_id, c.course_id, c.start_date, max(p.company) company
  from class c, person p, student s
  where substr(c.course_id,1,3) = 'OBI'
  and c.start_date >= SYSDATE-30
  and c.class_id = s.class_id
  and s.pid = p.pid
  group by c.class_id, c.course_id, c.start_date
  order by class_id, start_date, course_id
