sql - Why doesn't a "where not in (select statement)" criteria return the same resault as "where (select statement > parameter)"? -

-

यह एसक्यूएल स्टेटमेंट कोई रिटर्न नहीं देता: 

  SELECT [AutoNo], [PersonID] FROM [व्यक्तिटीबीएल] जहां किसी व्यक्ति को अपेक्षित नतीजे नहीं देता है:  
  
 
  SELECT [AutoNo], [PersonID] से [PersonTBL] WHERE (SELECT TOP 1 FDate FROM अनुवर्ती टीबीएल कहां अनुवर्ती टीबीएल। PersonID = PersonTBL.PersonID ORDER BY FDate DESC) & lt; '0 9/24/2014 ' 
 
 मुझे उन सभी लोगों को वापस करना होगा जिनके पास '0 9/24/2014' के बाद कोई फॉलो-अप है, पहले एसक्यूएल क्वेरी क्यों काम नहीं करती? दूसरा प्रश्न सही डेटा वापस करता है! 
 
 क्या पहली क्वेरी वापस एक ही परिणाम बनाने का कोई तरीका है (मेरा मतलब है "IN (चुनें)" का उपयोग करें)?

मुझे सभी व्यक्तियों को वापस करने की जरूरत है जिसने '0 9/24/2014 'के बाद, पहले क्यों काम नहीं किया!

आपका पहला कथन आपके में नहीं खंड का उपयोग कर रहा है कहां स्टेटमेंट यह आपको वही चाहता है जो आप चाहते हैं

I need to convert a QByteArray into a structure. I have such a structure: struct mavlink_attitude_t {/// & lt; Summary & gt; Timestamp (millisecond from system boot) & lt; / Summary & gt; Quint 32 Time_boot_ms; /// & lt; Summary & gt; Roll angle (rad, -pi .. + pi) & lt; / Summary & gt; Float roll; /// & lt; Summary & gt; Pitch angle (red, -p + + pi) & lt; / Summary & gt; Boat pitch; /// & lt; Summary & gt; Angle of O (Red, -P. + Pi) & lt; / Summary & gt; Float yao; /// & lt; Summary & gt; Angular Speed ​​Roll (Rod / S) & lt; / Summary & gt; Float rollspeed; /// & lt; Summary & gt; Pitch angular momentum (rad / s) & lt; / Summary & gt; Float pitchspid; /// & lt; Summary & gt; Yoga's angular momentum (RD / S) & lt; / Summary & gt; Float Yspeed; }; And I come from a Quetbeat Serial Port. I was already using the union but I think it can not be used for QByteArray, i...

c# - How to know the number of Threads created and limit the Tasks accordingly -

-
It is very clear that with task as async / await Instead of calling the asynchronous call threads , my question is: Is there a way to monitor threads while completing these tasks? This is because I can decide an optimal number of times for the thread that the thread does not eat too many CPU cycles at the same time (the CPU is intensive to handle the work). We take an example below (output is also mentioned) Although the program is completed in 5 seconds, but it has two threads (id = 1,4 ) if I increase the number of 6 instead of 2, then it creates 4 threads I know that this is the CLR thread OS thread (which is 4 in my machine Are), but I would like to know how they are mapped O (with actions) and use the same CPU. Is there any way to get it? Test code Fixed zero main (string [] args) {RunTasksWithDelays (). ); } Static async Task Run Task with Dislay () {Stopwatch S = Stopwatch. Startup (); Console.light line ("thread id =" + thread.content.trade.manag...
