ऐसा प्रतीत होता है (इस समुदाय के अनुसार और क्योंकि मुझे अन्य संग्रहित प्रक्रियाओं के परिणाम सेट का उपयोग करके नई चुनिंदा तालिकाओं में तालिकाओं के रूप में संग्रहीत प्रक्रियाओं का कोई उदाहरण नहीं मिला) कि MySQL या तो इसका समर्थन नहीं करता है या यह कि मैं जो करना चाहता हूं वह हास्यास्पद रूप से कठिन है करने की उम्मीद है।
इसलिए संग्रहीत कार्यविधियों को कॉल करने के बजाय मैंने इस अंतिम प्रक्रिया में प्रश्नों की प्रतिलिपि बनाई।
