Employees and departments database query with Sql -

-

मान लें कि मेरे पास एक जंक्शन टेबल है 

  कर्मचारी आईडी विभाग -------- ------ 1 1 1 2 1 3 2 1 2 2 2 3 3 1 3 2 4 1 5 2 5 3 6 1 6 2 6 3

इसलिए 1 कर्मचारी कर सकते हैं कई विभागों में काम करते हैं

मेरी समस्या यह है कि कौन सा कर्मचारी कई विभागों में काम करता है?

उदाहरण के लिए

यदि मैं एक कर्मचारी खोजना चाहता हूं जो विभाग के लिए काम करता है < कोड> 1,2,3 , परिणाम होगा: 1,2,6

अगर मैं एक कर्मचारी खोजना चाहता हूं जो विभाग के लिए काम करता है 2 & amp; 3 परिणाम होगा 1,2,5,6

अगर मैं एक कर्मचारी खोजना चाहता हूं जो विभाग के लिए काम करता है 1 & amp; 2 परिणाम होगा 1,2, 3,6

मैंने निम्नलिखित प्रश्नों के साथ कोशिश की 

  a) चयन भिन्न EmployeeId FROM dbo.EmpDept जहां में DeptId (2,3)

मुझे गलत परिणाम मिला 

  ख) dbo.EmpDept जहां से अलग कर्मचारी का चयन करें DeptId =  
  एनबी  ~>  
  
 मैं केवल अपने वास्तविक समय परियोजना परिदृश्य सिम्युलेटेड।  
 पहले से धन्यवाद   
 
  
 Itemprop = "text"> 
 यह प्रश्न उन सभी कर्मचारियों को मिलेगा जो 1 से अधिक विभागों के लिए काम करते हैं।  
  कर्मचारी का चयन करें, (*) कर्मचारी द्वारा dbo.EmpDept समूह से गणना (गिनती) *) & Gt; 1;  
 
 यदि आप विशिष्ट एम्पीडीपेट्स के एक समूह के बीच पार करने वाले कर्मचारियों के आंकड़ों को इकट्ठा करने की उम्मीद कर रहे हैं, तो आप स्वयं का उपयोग कर सकते हैं: 
 
  a.employeeid का चयन करें Dbo.EmpDept से, dbo.EmpDept b जहां a.employeeid = b.employeeid और a.deptid = 1 और b.deptid = 2;  
 
 इस पद्धति का उपयोग करके, आपको हर नए विभाग के लिए जोड़ना होगा जो आप चाहते हैं।

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

What is expire header and how to achive them in ASP.NET and PHP? -

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
