• replace the digital value with spaces

  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.

• 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

• Data in table, overwritten by the null value

  I work on writing a VI that simulttaneously reading speed and pressure, then record them on separate tables.  Hit a wall at about 90% of the way through.

  The data (represented by random numbers for testing sake) comes in this central loop case then a VI "add to the table."  Here is where it gets Sticky: when I use a null at the beginning of this table (top of the page highlighted) my data continually gets crushed in the row of the '0' table of each loop.  But when I leave aside the value zero (low highlighted) my data are added to the table very well, but when I stop the VI together and restart, the new data values are just added at the bottom of the table.  Any help would be appreciated.

  Forgive my drawings Caveman to a VI, learning of the system on mine and just happened to a point of optimization.  Thank you!

  -Blaster

  

  Hello Blaster,

  What you did (perhaps accidentally) is created a uninitialized shift register, which will retain its value until the VI leaves memory. This can be an extremely powerful tool and can be used to create things like Motors of the Action, but if you need to erase the data between tracks, you will need to do additional work.

  Looks like what you want to do is to maintain the value of your table, while the application is running, but clear is when restarting the application - which is correct?

  If this is the case, then you have a few options.  My recommendation would be to leave the uninitialized loop and use the primitive 'first call?"to check whether or not it is the first time your processing loop reiterated and replace the table 'used' with an empty array and null.

  You might also consider using initialized worldwide feedback nodes, or half a dozen other methods that have benefits and different disadvantages.  Congratulations on the job through the application, by the way!

• 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)
                      {
                          safetyTable = new Hashtable();

                      }

                      {
                          orderedKeys=new Vector();
  
                          if (safetyTable.size()>0)
                          {

  I have to remove the NULL values in column 1, the problem is that the position of the NULL values are not fixed, and it can be any position. If all the lines of the columns are null, then throw it away.

  If multiple NULL values are here so I have to do the math as follows to update null with the eigenvalues

  1. If the first line is null then take the 2nd value in row and update it.

  2. If the lines between both is null then take avg of prev and next value not null and refresh it.

  3. If the last value in the column is null, then then take prev and update, in this case last two are null, so I have to take value of prev 14 value line update in

  15th and 16th ranks.

  I want to put this pl/sql logic, somehow, that I thought have loop and counter aapproach and loops through the elements and check and update.

  But always looking for something better before looking to write code. No idea or help will be useful for me.

• check NULL values with expressions

  I'm having a problem with an expression that I work with.

  I'm trying to produce a dynamic graph (among other information) that seems to be controlled by a stream - stream artificial is created by a handful of sliders and a wiggle expression.

  The chart is a simple graphic line which works very well. It is created with a null value (MarkPos) that the position is controlled by Captain wiggle expression that I've mentioned before, that follows.

  This next bit is where I have problems:

  I want to score minimum or maximum, the line has reached on the chart by moving a dotted line, one for weak points and the other for the top.

  Focus only on the bottom line;

  I have the following expression associated with the line, which brings together the current position of the value null (MarkPos) and compared with the current position of the line to see if it has all moved further away down, if she has it moving the line to the new pos are lower. However, all that happens is the line following the null value.

  x = thisComp.layer("MarkPos").transform.position.valueAtTime (time) [1];

  y = transform.position.valueAtTime (time) [1];

  z = transform.position.valueAtTime(time-thisComp.frameDuration) [1];

  If (x > y) {}

  [0, x]

  } else {}

  [0, z]

  }

  After a lot of debugging, I now know the issue is with the else statement - what his weight is compensating the to the high movement frame by frame 1 - so how do you define an order of "keep your current position in y ' in this case?

  [0.1] just it back to its original position and it is not possible to just have the ' if(x>y) {[0, x]} "bit without the"else {}.

  Suggestions fo how to fix this, or a better way to do it?

  This should give you the value of y min:

  p = thisComp.layer("MarkPos").transform.position;

  minVal = 999999;

  for (f = timeToFrames (time); f > = 0; f-) {}

  minVal = Math.min (digraph, p.valueAtTime (framesToTime (f)) [1]);

  }

  [value [0], minVal]

  and this should give you the most:

  p = thisComp.layer("MarkPos").transform.position;

  maxVal = - 999999;

  for (f = timeToFrames (time); f > = 0; f-) {}

  maxVal = Math.max (maxVal, p.valueAtTime (framesToTime (f)) [1]);

  }

  [value [0], maxVal]

• Is it possible to replace the hard drive with an SSD? or would it be too expensive?

  Is it possible to replace the hard drive with an SSD?

  or would it be too expensive?

  Yes.  There are several alternatives.  I found a way relatively inexpensive, using a map of mSATA (very small SSD) and an adapter to connect it to the connector IDE 44 pin internal of my PowerBook.  It works very well.  Rather than repeat what I posted previously, you can watch these two topics (which also has good info, other users)

• Re: Tecra A9 - 11M - replace the HARD drive with a larger

  I have a Tecra A9 - 11 M with Windows XP Professional installed. I would like to replace the hard drive with a larger drive and install Windows 7 Professional.

  Any suggestions on recommended records say 500 MB?

  Difficulties to install Windows 7 on this model?

  Hey,.

  > Any suggestions on recommended records say 500 MB?
  I assume you mean 500 GB and not 500MB, right? ;)

  Well, the Tecra A9 already supports SATA interface and there is no limit of capacity on SATA interface, so you can install a 500 GB HARD drive or more (750 GB, etc.). Just make sure that it s 2.5 SATA HDD.

  You can choose each brand of HARD drive because each model will not work. You can buy a Toshiba HDD, Western Digital HARD drive or another. No problem ;)
