asp.net - Update main table based on rows from a secondary table -

-

मेरे पास एक कर्मचारी ड्राइंग प्रकार आवेदन है, टेबल दिखते हैं: 

  कर्मचारी , नाम, चयनकार्ड) चयन (कर्मचारीआईडी, आईपीएड्रेस)

अब मुझे एक अपडेट क्वेरी की आवश्यकता है जो प्रत्येक कर्मचारी आईडी के लिए चयन की संख्या को गिना जाएगा (अद्वितीय आईपीड्रेसस के साथ), और चयन को अद्यतन करें तालिका कर्मचारी।

ऐसा कुछ काम करना चाहिए: 

  के साथ चयनकॉइंट (एम्प्लॉइएड, सिलेक्शनकाउंट) एएस (सेलेक्ट एस एम्प्लॉइआईडी, COUNT (अलग आईपीएड्रेस) एस चयन के ग्रुप द्वारा एस एम्प्लॉइआईडी द्वारा) चयनकर्ता कर्मचारी एसईटी सिलेक्शन क्वालिटी = एसईसी। सिलेक्शन क्वांटमेंट से सिलेक्शन कैप एसडी WHERE ID = sc.EmployeeId

इसकी जांच नहीं की, ताकि वाक्यविन्यास पूरी तरह से सही न हो।
