sqlite3 - How can a create an SQL statement that offers multiple sum() totals? -

-

मेरे पास इस तालिका में SQLite3 है। 

  नाम | मात्रा | मूल्य | श्रेणी ----------------------------- जेड | 1 | $ 25 | एक वाई | 2 | $ 50 | बी एक्स | 3 | $ 100 | एक डब्ल्यू | 1 | $ 6 | सी वी | 2 | $ 15 | बी यू | 1 | $ 26 | एक

मैं प्रत्येक श्रेणी के लिए कुल (मात्रा * मूल्य) और एक एकल एसक्यूएल स्टेटमेंट के साथ सभी श्रेणियों की कुल (मात्रा * मूल्य) कैसे प्राप्त कर सकता हूं? यह वह आउटपुट है जिसे मैं खोज रहा हूं: 

  ए - $ 351 बी - $ 130 सी - $ 6 कुल - $ 487

क्या यह संभव है?

श्रेणी के अनुसार अपने_टेबल समूह से श्रेणी, राशि (मात्रा * मूल्य) चुनें
"post-text" itemprop = "text"> 
  सभी श्रेणी के रूप में 'कुल' चुनें , आपके_table से योग (मात्रा * मूल्य)
