• How to find the ANGLE b/w two edges in Oracle Spatial

  How to find the ANGLE b/w two edges on Oracle Spatial. I have two edge connected on the same node. I wanted to know the angle betwwn them. Can someone help me?

  Ok. My first example is an approximation. Further you get North or South of the Ecuador, gets the more vague.

• Find the intersection/union between two cards

  Hello.
  I'm trying to find out the changes of State between the two cards.
  I have two cards A and B, what I need to do is to find keys in A that exists in key and B in B that does not exist in a..
  If the key exists in both A and B I want to compare the values of these keys.
  What would be the most effective way to apply it.
  My first plan was to make a loop on the keys has to find b and browse the keys b and find in A, but I guess that there is a more efficient algorithm.
  I think also on the use of java.util.Collections to find union-intersection between the keys in the cards, but then I need to do a search in the two
  maps.
  Any suggestions?

  A state change occurs if there is a new node in the cluster, which means a new entry to the card since the last audit, or if a node

  By your senario above, I don't think that you have two objects on the map, there is a single object and you want to report the change in the GUI, whenever an object is the value added, deleted or by itself is changed (key is the same) to the map.

  Then, I suggest below things:
  (1) override hashcode and equals method. (Because each time the methods put and putAll are called the hash code equal method checks in the bucket for the equal and similar hash code and if its equal, and then change the GUI for the existing map).
  (2) as suggested earlier, substitute methods of deletion. (Whenever an object is deleted, accordingly you can change the GUI).
  (3) as was suggested earlier, override a method put and putAll (whenever a new object is added, so you can change the GUI).

  And to do this, I don't think you have to browse the map.

• Calculating the distance between two images... ?

  Hello

  I'm trying to calculate the distance between two images (A and F - there are other images between A and F), but I can't seem to understand how to make good sense.

  Image A.x is "(stage/2)-(A.width/2)" and the image of F.x is "provable - imgSpace" which is a negative value (all images x is a negative value for image A.x). "

  In my view, the calculation is F.x - A.x, and although it could be good I still ned the value to be non-negative.

  Does anyone know how to do this?

  Thanks in advanse...

  I think you can find out the distance with this equation,

  var len:Numer = Math.abs (A.x - F.x);

• Find the minimum date on multiple columns

  Hello
  
  I have two questions to find the minimum date on several columns:

• PL/SQL loop to find the minimum value

  I want to find the minimum value from a table using the pl/sql loop

  1 ABC 2000

  If rec.sal > fmin then

  end if;
  end loop;

  end;
  /

  I want to output 2 on top of code.

  Thanks in advance

  Why PL/SQL? SELECT MIN (SAL) OF TEST will be more rapid and much less coding. In any case:

  declare

  number of v_min_sal;

  Start

  for v_rec in a loop (select sal from emp)

  If nvl (v_min_sal, v_rec.sal + 1) > v_rec.sal

  then

  v_min_sal: = v_rec.sal;

  end if;

  end loop;

  dbms_output.put_line (' lowest salaray is "' |") v_min_sal | '"');

  end;

  /

  The lowest Salaray is "800".

• find the distance between two major axis chart point cloud

  Hello

  I have a scatter chart. Its the y-axis AutoScale property is set to false. The major and minor axes are by default. Interval is set by default.

  When draw the graph divisions displayed on the axis are defined according to the range provided. Sometimes, the interval between the major divisions, that is exactly what is defined in the Interval property and sometimes this isn't the same thing. As mentioned in the help the AutoScale property is set to true, sometimes by himself in order to avoid the congested labels.

  What I find is the distance beween two major axes of the value axis, as the interval is not the same as set in the property.

  Kindly let me know how to calculate the interval.

  Kind regards

  Nihad.

  yAxis1.AutoSpacingMajorInterval

  Replace yAxis1 by what is called your axis y on the scatter graph. If you don't know what it is, right click on the axis are the scatter graph, and then select Edit YAxes. Then a box will appear and you can see how it's called in the members section.
