sql - Order by in a subquery -

यहाँ मेरी क्वेरी है:

  काउंट (i) में select count (1) में एमआईसीएआरएक्सिस्ट्स CAR से ID_MODEL = (मॉडल से आईडी चुनें जहां TYPE = 'SUV' और rownum & lt; = 1 आदेश DATE_UPDATE तक);    मैं  गिनती  से  CAR  में नवीनतम पंक्तियों का नवीनतम संस्करण ( DATE_UPDATE desc ) करना चाहता हूं  मॉडल   'एसयूवी' । 
  इस प्रश्न के साथ, मुझे  ORA-00907 मिला है: सही कोष्ठक नहीं मिला  ... 
  मैं ओरेकल डाटाबेस 10 का उपयोग कर रहा हूं।

  
  उस त्रुटि के बारे में पहले भूलें आपकी क्वेरी कार्यात्मक रूप से गलत है 
  आप 12c पर नहीं हैं, इसलिए आपको  पहले  ऑर्डर करना होगा और फिर  का उपयोग करें जहां rownum = 1 < / कोड> बाहरी क्वेरी में वरना, 12 सी में, यह शीर्ष-एन क्वेरी के रूप में  पहले 1 पंक्तियों को केवल  
 
  लाने के लिए काफी आसान है

From the MongoDB site:  "Documents stored in a collection require a unique _id field which acts as the primary key. Since ObjectIds are small, most likely is unique, and Fast to generate "    The primary key and probably some other data are related to them.   If you want to keep the id like 1,2,3,4,5 ... you have to set u...
