android - How to optimize SQLite database fetching time -

-

I have 6384 records in my database and I am using the following query: 

  SELECT T T_name, S.s_code, S.s_name, R.s_code, R.s_name, M.arrival_time, L.arrival_time, M.dest_time, MTNID, SID, RID from Trincilchudule M, Trencheschudual L, Train T, Station S, Station R, where S.S.name = 'Versova' and RS_Name = 'Ghatkopar' and M. Arrival-time & gt; '00: 00: 00 'and M. Arrival_time & lt; L. Arrival_time and MTNIID = LTN.ID and M.Dest_time = L.Edest_time and T.ID = MTNID and SID = M.Station_ID and R .id = L.Station_ID   
 This query takes 8 seconds to fetch data. I have indexed my table, but the time is being taken only for 2 seconds.  
 Schema:  
  create table [station] ([ID] INTEGER tap primary key AUTOINCREMENT, [s_code] VARCHAR (10) not tap, [s_name] VARCHAR (50 Not faucet); Create Table TRAIN_SCHEDULE (ID INT, station_id INT, train_id INT, arrival_tile NUM, departure_time NUM, dest_time NUM); Create a table train (ID INT, t_name text); Train index idx_arrival_time Make train_sebel (arrival_time); Train Make Index idx_dest_time train_schedule (dest_time); Create a train (id) on index idx_id;   
 How can I improve it?   
 
 
 You can check which indexes are being used.  
 In this query, the database needs to be scanned through the  STATION  table; This will improve in an index on the name column (though not with such a small table):  
  the construction index station_name at the station (s_name);   
 In addition, the  TRAIN_SCHEDULE  lookup on the table is done on many columns. Query Optimizer can not use more than one instance of an example table, so you should create a multi-column index. And a non-parallel comparison column must be finalized (see):  
  create index Schedule_Station_Train_DestTime_Time on training (station_id, train_id, die_time, arrival_time);   
 Also execute once to help Optimizer choose the right index.

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...
