आप info_schema (हारून ... मुझे पता है, INFORMATION_SCHEMA;) का उपयोग करके अपना "तालिका बनाएं" कथन बना सकते हैं।
मैंने इस उद्देश्य के लिए कुछ कोड लिखा है, लेकिन यह INFORMATION_SCHEMA का उपयोग नहीं करता है। मुझे पता है, अगर पुराने सिस्टम टेबल का उपयोग करता है जिन्हें शायद हटाया जाना निर्धारित है। यह कुछ अतिरिक्त जानकारी भी जोड़ता है (जिसे आप हटा सकते हैं, क्योंकि आपको इसकी आवश्यकता नहीं है)। बस तालिकाओं की सूची को @INCLUSIONLIST में डालें और इसे उस डेटाबेस में चलाएँ जहाँ तालिकाएँ रहती हैं।
SET @INCLUSIONLIST = '|table1|table2|';
