• Purpose of "null is not null" and "null is null" statements

  Hi all

  Please can someone explain the purpose of these statements and what it means.

  1 null is not null

  2 null is null

  (a) NULL should be treated in a special way in the comparisons - see values NULL SQL - IS NULL and IS NOT NULL or SQL ISNULL(), NVL(), IFNULL() and COALESCE() functions

  (b) If you really clauses Null is not null or Null is null (meaning: the first is not a variable) it could replace "always wrong" and "always true"; Maybe in some test queries

• difference between IS NULL and = NULL

  Hello guys,.
  
  10 gr 2, what is the difference between IS NULL and = NULL
  
  Thank you
  Imran

  NULL is not equal to zero or a specific value
  NULL means unknown

  the first form will work, given that the value of a field may be unknown (= IS NULL)

  the other will not work, because a specific value is not equal to unknown
  the first is the correct form, the second will always be false
  same NULL = NULL can be distorted, because unknown is unknown

• One of my favorites of the toolbar is "null" and cannot be accessed or deleted, all the patches?

  The bookmarks bar displays only the 'left' of the null bookmark bookmarks. When I open the bookmark list, the offending link is always visible, but when highlighted, it shows no url.

  This may be a problem with the places.sqlite file that stores the bookmarks and history.

• road cars motion to follow leader (object null) and maintain a fixed distance

  I am trying to create a model of my local intersection where a car will facilitate a stop at a red light and the string of cars behind will follow and stop a remote fixed behind the car to the front desk

  I'm so close and yet so far to the solution to this, I'm still pretty new to expressions if I need a little help. I previously made a highway with a 1 000 cars using a tutorial dedicated to the CG snake Jerzy Drozda Jr to maltaannon.com, but from the next project that I realized that this method did not allow the cars maintain a fixed distance.

  
  

  I then read Dan Ebberts "creation of trails" section of www.motionscript.com and found that of Jerzy Drozda method, so that the ideal for small projects, is problematic with a large amount of objects because it uses a phrase "cascade", where in one layer refers to the previous layer, which refers to the previous layer, etc. This can significantly increase the amount of work After Effects needs to do to each image. I got first hand with this when I did my freeway. After effects was almost impossible to use because there was a lag of 10 seconds after each click.

  
  

  Which brings me to my current problem, get this expression to work I have attached the file that I work as a download link for my reader of Google here
  

  
  

  Here's the original motionscript.com formula - if you want to see just research guide "//start model query time" in Google and click on the first link.

  
  

  I tried so many things with this expression, but the dam car simply refuses to follow the null object!
  

  
  

  in the Position property:

  STRT = 0; time of beginning of model movement

  end = 4.0; end time of query model

  t = thisComp.layer ("template");

  offset = (t.effect ("offset")("Slider")/100) * (index - 1);

  travel = linear (t.effect ("travel")("Slider")/100, strt, end);

  t.position.valueAtTime(travel-offset)

  in the Orientation property:

  
  

  STRT = 0; time of beginning of model movement

  end = 4.0; end time of query model

  t = thisComp.layer ("template");

  offset = (t.effect ("offset")("Slider")/100) * (index - 1);

  travel = linear (t.effect ("travel")("Slider")/100, strt, end);

  If (trip < = offset) {}

  VECT = t.position.velocityAtTime (0);

  } else {}

  VECT = t.position.velocityAtTime (travel - offset);

  }

  lookAt (position, position + vect)

• Plugin using the html bridge with DataProvider which includes DataProviderAdapter and PropertyProviderAdapter

  Hello

  We have extended our plugin to include views that use the html Bridge.

  The first step was to display the data on our custom types. Applications range from the gui - to the DataAccessControlller as seen in the samples of chassis.  Then a RequestSpec is generated and sent to the dataService:

  dataService.getData (requestSpec).

  The dataServices then forwards the request to our DataProviderAdapter - as in the example. Everything works fine.

  Now we want to rewrite some of the other views (for guests, vcenters etc.) to use the html Bridge as well, but these views use PropertyRequestSpecs for data.  These requests should be sent to the PropertyProviderAdapter - where all code wrote

  I tried something like the following:

  If (targetType is customType) - build a RequestSpec and send it to the dataService

  If (targetType == managedObjectType (as a host) - build a PropertyRequestSpec and send it to the dataService.)  This

  does not work, because the dataService only takes RequestSpecs as the parameter to GetData.

  I looked at the samples for vsphere and saw that they also make RequestSpecs and send them to the dataService.  These applications, however, do get sent to their PropertyProviderAdapter - and I have found no difference in the way in which the RequestSpecs were built.

  The difference between the 2 samples and my DataProvider, it is that I have both a DataProviderAdapter and a PropertyProviderAdapter in the same DataProvider.

  So the question is: is it possible to have the dataService send the request to the adapter is correct (or both) - based on the targetType?

  Thanks for any ideas

  Cathy

  The DataService interface is:

  public Response getData(RequestSpec request);
  

  RequestSpec has a picture of QuerySpec

  public QuerySpec[] querySpec;
  

  The QuerySpec a ResourceSpec and constraint:

  public ResourceSpec resourceSpec;
  
  public Constraint constraint;
  

  In the ResourceSpec you have PropertySpec

  public PropertySpec[] propertySpecs;
  

  In the PropertySpec you have the property names:

  public String[] propertyNames;
  

  Now after all this being said, if you have a PropertyProviderAdapter, who provides the 'foo' VirtualMachine type property, you must pass the DataService a RequestSpec with

  ObjectIdentityConstraint c = new ObjectIdentityConstraint();
  c.target = vmMor;
  c.targetType = "VirtualMachine";
  requestSpec.querySpec[0].resourceSpec.propertySpecs[0].propertyName[0]="foo";
  requestSpec.querySpec[0].constraint = c;
  

  Now when you pass this requestSpec, the DataService will build the PropertyRequestSpec and call your adapter.

  Based on your last post that only good data must match exactly and your definition of junk:

  WHERE (decode (substr (A.col5, 1, 1), ' ~ ', 'junk mail', null, 'null', 12/31/9999 ', "junk," A.col5 ") = decode (substr (B.col5, 1, 1), ' ~ ', 'junk mail', null, 'null', 12/31/9999 ',"junk", B.col5"))

  AND (decode (substr (A.col6, 1, 1), ' ~ ', 'junk mail', null, 'null', 12/31/9999 ', "junk," A.col6 ") = decode (substr (B.col6, 1, 1), ' ~ ', 'junk mail', null, 'null', 12/31/9999 ',"junk", B.col6"))

  And so on for the six columns.  This assumes that this junk * still * starts with a ~.  In addition, it assumes that the unnecessary and null words are not in the form of good data.

  You should not ' equal to ' a NULL string. A NULL string is an unknown value in Oracle. You can't IS NULL or IS NOT NULL.
  You should not perform
  = NULL
  =''
  ! = NULL

• Is it possible to change the nulls and numbers?

  Experts-
  
  I have xml... PRODUCT GROUP, PRODUCT, QUANTITY, PRICE columns. (QUANTITY, PRICE are numbers)
  
  There are empty values here and there in the price, the quantity columns...
  I'm my XML in the co-location model and thus have <? sum (current - group (/price))? > and <? sum (current - group (/price))? > in the report.
  
  Because NULL values, it gives me NaN in the sum.

  I wasn't expecting to see because the doc said about scan limited index full "...". and at least one column in the index key has the NOT NULL constraint,"which would be foolish to say if the rowid was what filled that. There are currently only 2 factory codes and code 1 company (not nulls - Oracle does know that?), so I was kind of expected Oracle to reorder the predicates with an index skip scan. Take a fresh look on the doc, I wonder if I should not specify the company code in the query and maybe spend employee and job_number in the index. I hope it's obvious that this index has been added for other queries. This request could be taken out a change in the requirements of anyway, but I don't know when.

  Joel,

  I just had this 'already seen' (new) sense to speak of it.

  Mentioning the reference 11.1 gave you:
  

  
  + "Index full scans are an alternative to a full table scan when the index contains all the columns needed for the query, and at least in the index key column has the constraint NOT NULL. A full scan can access the data of the index itself, without access to the table ' + '.
  

  This so obviously must be bad that I couldn't decide if I was proven wrong or was amazed to find that I couldn't he show the falsity. (Just because something is obvious, it does not mean it is true – Terry Pratchett.)

  However, here is the obvious counter-example - that I came across 8.1.7.4 because it's the oldest version of Oracle that I have now:

  create table t1
  as
  select
       rownum               id1,
       rownum               id2,
       rownum               id3,
       lpad(rownum,10,'0')     small_vc,
       rpad('x',100)          padding
  from
       all_objects
  where
       rownum <= 10000
  ;
  
  create index t1_i1 on t1(id1, id2, id3);
  
  begin
       dbms_stats.gather_table_stats(
            ownname           => user,
            tabname           =>'T1',
            cascade           => true
  
       );
  end;
  /
  
  set autotrace traceonly explain
  
  select
       /*+ index_ffs(t1) */
       id1, id3
  from
       t1
  where
       id2 = 99
  ;
  

  No 'NOT NULL columns". But any line I will have a (non-null) value for id2, then it should be in the index - then Oracle should be able to do a full scan and get the right answer. Here is the map (I have no need of Council - but your configuration may be different):

  Execution Plan
  ----------------------------------------------------------
     0      SELECT STATEMENT Optimizer=ALL_ROWS (Cost=4 Card=1 Bytes=12)
     1    0   INDEX (FAST FULL SCAN) OF 'T1_I1' (NON-UNIQUE) (Cost=4 Card=1 Bytes=12)
  

  If you change the predicate to: "id2 is zero", then the only legal path is an analysis.

• Hide/show text when field null and not null

  I discovered how only display a field in a query using Dreamweaver 8, PHP, and MySQL when the value of the field is zero in showing this:
  http://www.Adobe.com/cfusion/webforums/Forum/MessageView.cfm?forumid=12 & catid = 189 & ThreadID = 1005921 & arctab = & highlight_key = y & keyword1 = see the % 20region
  
  However, how can I put text next to the field data when there are data in the field? Therefore, 1) hide textes_ data when the value in the record field is zero and 2) show text data and when the fields of records is not null.
  
  I tried to put the text with the echo, but then the text is displayed without the data from the field when the field is null.
  
  The code I have so far is:
  <? PHP if (! is_null ($row_rsProperties ['US_List_Price'])) {echo $row_rsProperties ['US_List_Price'] ;}? >
  
  rsProperties is the recordset and US_List_Price is the field
  
  Thank you!

  The is_null() function checks a NULL value. I suspect that your
  the fields are empty instead of NULL. Change the code to do this:

  
  "Text". $row_rsProperties ['US_List_Price'] ;} ?>

• Is not null and null join

  Hi, I am trying to correctly display a list of tasks for a project, but without a join with the project number (which I was aware of) and the employee table, I get over 500 results.
  
  The task can be created without a responsible employee of her as well, so that the page does not require the field to fill.
  
  Here's the SQL, someone at - it ideas?
  

  select
      pd.pk_proj_detail_id    "Task Number",
      pd.task_title           "Task Title",
      pd.DETAIL_STATUS        "Task Status",
      pm.name                 "Associated Project",
      pps.last_name||', '||pps.first_name||', '||pps.middle_initial||'.' "Assigned Employee",
      pd.TRACKIT_NUMBER       "TrackIt! Number", 
      pd.CREATEBY_DATE        "Date Entered",
      pd.DATE_BEGIN           "Date Began",
      pd.ESTIMATED_DATE       "Estimated Completion Date",
      pd.DATE_END             "Date Completed"
  
  from
      PROTRAC_DETAIL pd,
      protrac_master pm,
      cobr.vw_pps_payroll pps,
      resources r
  
  where
      pd.fk_proj_master_id = pm.PK_PROJ_MASTER_ID
      and r.fk_master_id = pm.PK_PROJ_MASTER_ID
      and (r.emp_id = pps.emple_no
          or r.emp_id is null)

  Hello

  Replace:

  res.last_name||', '||res.first_name||', '||res.middle_initial||'.' "Assigned Employee",
  

  with

  res.last_name
  ||    CASE
            WHEN  res.first_name IS NOT NULL
            THEN  ', ' || res.first_name
        END
  ||    CASE
            WHEN  res.middle_initial IS NOT NULL
            THEN  ', ' || res.middle_initial || '.'
        END     AS  "Assigned Employee",
  

  Here's why:

  If all res columns have a NULL value (which can happen because of the outer join), then

  res.last_name||', '||res.first_name||', '||res.middle_initial||'.' "Assigned Employee",
  

  is equivalent to

  NULL ||', '|| NULL ||', '|| NULL ||'.' "Assigned Employee",
  

  The punctuation is there to separate the three columns.
  If a column if the NULL value, you don't need to separate, so you need to make some sort of if-else operation to test if the punctuation is needed and show only if it is necessary.

  CASE expressions above will also give you a nicer output if some columns are set to NULL, but others are not.
  (For example, if the middle_initials are rarely saved.)
