ms access - SQL Nested Select with faculty members -

- 

  SELECT FacSSN, FacLastName, संकाय से facDept जहां फ़ॉस्सेन (जहां से ऑफ़सेट = 'शीतकालीन' मेरे पास एक सवाल है जो परीक्षा के लिए संशोधन के लिए है, यह सवाल है: नाम की सूची बनाएं। (पहले और आखिरी) और संकाय विभाग, जो केवल सर्दियों की अवधि 2006 में पढ़ रहे हैं  
 हालांकि एक व्यक्ति जिसकी सर्दियों 2006 और गर्मियों 2006 में व्याख्यान है, सवाल उस व्यक्ति की सूची नहीं करना चाहता है <   
 
 
 इनके बजाय EXISTS खंड का उपयोग करने की कोशिश करें:  
  SELECT FacSSN, FacLastName, फैकल्टी से फैसिलिटी जहां मौजूद है (जहां से ऑफ-ट्रिम = 'शीतकालीन' और ऑफइया की पेशकश का चयन करें आर = 2006 और FacSSN = फैकल्टी। FACSSN) और नहीं (जहां से (ऑफ़टर्म & lt; & gt; 'शीतकालीन' या ऑफयोर & lt; & gt; 2006) और FacSSN = Faculty.FacSSN) का चयन करें  
 < P> वहाँ भी subqueries में DISTINCT का उपयोग करने की आवश्यकता नहीं है।

I was trying to write a solution, which is a different and a manual for calculating a mean and STD The way. I have created a = ["Apple", "Banana", "Cherry", "Apple"] B = [3,4,7,3] C = [5,4,1,4] D = [7,8,3,7] Pd DF = PD to import pandals DataFrame (index = class (4), column = list ("ABCD")) DF ["A"] = A DF ["B"] = BDF ["C"] = C DF ["D"] = D Again, I made a list of A duplication. Then I went through the group all the time of the objects and calculated the solution. import as np l = list (set (df.A)) df.groupby ('A', As_index = False) listMean = [0] * len (df.C) ListSTD = [0] * L in the LAN (df.C) X: s = np.mean (df [df ['A'] == x] for C =.) = Z = [index for index, enumerate In the object (df ['a']. Value] x == item i for z: listMean [i] = s in: s = np.std (df [df ['a'] == X] .cvalues) z = index for index, enumerate item (df ['a']. Value) if x ==...
