हम अद्वितीय गैर-पंक्तियों के साथ पंक्तियों को वापस करने का प्रयास कर रहे हैं उस यूजरआइड के लिए अधिकतम साइक्लेनंबर से मिलान करने वाला पीटिंग यूजर आईडी अभी क्वेरी विभिन्न cyclenumbers के लिए एक ही userid कई बार लौट रहा है। हमें पूरी तरह से निश्चित नहीं है कि सही क्वेरी के साथ कैसे आगे बढ़ना है। किसी भी मदद की सराहना की जाएगी।

आप इसे अपने उपखंड के साथ कर सकते हैं जहां खंड की तरह कुछ: 

  का चयन करें u.UserID, UserLastName, UserFirstName, उपयोगकर्ता नाम, अधिसूचित, CycleNumber, CycleCurrentStep, CycleDateReported, से [उपयोगकर्ता] cycleid यू पर (u.UserID = c साइकिल ग में शामिल होने के लिए छोड़ दिया। UserID) UserDivSection हम पर शामिल होने के (u.UserID = us.UserID और us.DivSectionID = 26) जहां cyclenumber = (अधिकतम (cyclenumber चुनें) चक्र से जहां cycle.userid = u.userid)
< P> मुझे यद्यपि UserDivSection भाग के बारे में निश्चित नहीं है।
