मेरे पास एक छोटी सी समस्या है

  1. तालिका (user_table)

    आईडी | उपयोगकर्ता नाम | नाम | पासवर्ड

  2. तालिका (न्यूज़लेटर)

    आईडी |

  3. सारणी (न्यूज़लेटर_पॉस्ट्स) & lt; - यह तालिका मेरी समस्या के लिए बहुत महत्वपूर्ण नहीं है।

User_table लचीला है, इसका मतलब है, कभी-कभी मैं नए उपयोगकर्ता बना देता हूं, कभी-कभी मैं उपयोगकर्ता हटा देता हूं।

न्यूज़लेटर तालिका भी लचीला है।

इस महीने 

  1 | 12345678

अगले महीने 

  2 | 23456789

और इतने पर ...

लेकिन मैं कैसे सभी समाचार पत्रिका और सभी उपयोगकर्ताओं के लिए एक पढ़ा / अपठित तालिका बना सकता हूँ मेरे पास लगभग 100 उपयोगकर्ता हैं और प्रति वर्ष 12 न्यूज़लेटर हैं।

ग्रीटिंग्स

डेनिस

आप एक तालिका बनाते हैं जो न्यूज़लेटर तालिका को उपयोगकर्ता तालिका से संबंधित करती है। 

  न्यूज़लेटर_यूज़र ---------------- id user_id newsletter_id एक पंक्ति के अस्तित्व में घटित होना चाहिए (डालें) जब कोई उपयोगकर्ता समाचार पत्र पढ़ता है यदि कोई पंक्ति नहीं है, तो उपयोगकर्ता ने समाचार पत्र को नहीं पढ़ा है User_id, newsletter_id पर एक अद्वितीय अनुक्रमणिका बनाएं
