sql server - Inside a stored procedure. How can I tell if an UPDATE worked? -

मेरे पास है: 

  अद्यतन तालिका 1 एसईटी कॉल 1 = 'एक्स' WHERE Val1 = @ Val1   
 मैं यह कैसे बता सकता हूं कि उसे अद्यतन करने के लिए एक पंक्ति मिल गई है या नहीं?  
 इसके अलावा मैंने SET NOCOUNT पर गौर किया  
 क्या कोई मुझे बता सकता है क्या यह क्या करता है?   
 
 
 का उपयोग करें  @@ ROWCOUNT  से प्रभावित पंक्तियों की संख्या प्राप्त करने के लिए निष्पादित बयान संग्रहीत कार्य में:  
  अद्यतन तालिका 1 SET Col1 = 'X' WHERE Col21 = @ val1 यदि @@ ROWCOUNT & gt; 0 शुरू - अधिक तर्क निष्पादित करें - और भी अधिक तर्क निष्पादित करें   
 यह जानना पर्याप्त है कि क्या अपडेट काम किया है। आप अपने डेटा परिवर्तनों का पूरा विवरण प्राप्त करने के लिए  आउटपुट सम्मिलित ....  तर्क का उपयोग कर सकते हैं। इसे यहां देखें

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...

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...

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...
