sql - Nested cursors, multiple result sets -

-

I am using SQL Server stored procedure to generate Excel reports. Basically, each "entry" in the report has three parts: objects, observations and points. The comments are in reference to the primary key of an object, and there is a reference to an overview of the number. It is a connection between parts (sorry if my terminology is closed, then I am being used to write in C # or Java, but still I am learning SQL.)

I want to The output should be like this: 

  - Object - All objects associated with that object - Under each observation, all points associated with that observation should be   
 And repeat for each object. I am using a cursor to create all the comments with each object, but I can not get points to come under every observation  
 I have read all on the internet that the cursor Bad, and I think nested cursors are very bad but I still have it. If you know a better way to do this, please let me know. I am open to completely reconstructing this if necessary.  
  announcement objects @Object_Cursor announced cursor @Observation_Cursor cursor Declaration for @i announced @j integer @row Integer = 1 set @Object_Cursor cursor = int (select PK_ObjectId) OPEN @ Object_Cursor FETCH while @ ahead of @Object_Cursor @@ FETCH_STATUS = Start select PK_ObjectID, name, select the timestamp of objects where PK_ObjectID = @i SET @ Objheshn_ Cursor = the CURSOR (SEK objection from @PK_ObservationID) OPEN @ Observation_Cursor @j Do not check next @Observation_Cursor while @@ FETCH_STATUS = 0 start timestamp , Notes, comments from users where FK_ObjectId = @i FK_ObjectID select Latitude, the points where ordered by Lng FK_ObservationID = Fetch @j Next @Observation_Cursor from @ Jay finally @i end off @Observation_Cursor deallocate @Observation_Cursor off @Object_Cursor deallocate @Object_Cursor Next Do not Launch From @Object_Cursor   
 In some way I feel like the order I am executing these loops, but I'm not able to get it. The current output is:  
  -Object- Observations for that object -mate point result set   
 Repeated results for the same object several times First for the next one, and the points are always empty.  
 Any help or signal in any direction is greatly appreciated.   
 
 
 The C # loop argument is not how you want to think about SQL ... 1 The statement is always better.  
 I think this is closer to what you have ... I'm guessing some things in my keys.  
  Select objects (pick up your fields here) items left from objects.PK_ObjectID = Observations.FK_ObjectID Pts.FK_ObservationID = observations.pk_observation_ID   Include comments when joining / div>

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

-
I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
