টার্মিনাল থেকে সমস্ত টেবিল একবারে ফেলে দেওয়ার সহজ সমাধান।
এটি আপনার মাইএসকিএল শেলের ভিতরে কয়েক ধাপ জড়িত (যদিও এক ধাপের সমাধান নয়), এটি আমার কাজ করে এবং আমার দিনকে বাঁচায়।
সার্ভার সংস্করণে কাজ করেছেন: 5.6.38 মাইএসকিউএল কমিউনিটি সার্ভার (জিপিএল)
পদক্ষেপগুলি আমি অনুসরণ করেছি:
1. generate drop query using concat and group_concat.
2. use database
3. turn off / disable foreign key constraint check (SET FOREIGN_KEY_CHECKS = 0;),
4. copy the query generated from step 1
5. re enable foreign key constraint check (SET FOREIGN_KEY_CHECKS = 1;)
6. run show table
