কিছু পদ্ধতি ব্যবহার করে আপনি যখন কোনও টেবিলের অনুলিপি তৈরি করেন আপনি সূচীগুলি, পিকে, এফকে ইত্যাদি হারাবেন উদাহরণস্বরূপ এসকিউএল সার্ভারে আমি বলতে পারি:
select * into dbo.table2 from dbo.table1;এটি টেবিলের কেবল একটি সাধারণ অনুলিপি; সমস্ত সূচক / সীমাবদ্ধতা অনুপস্থিত। আমি কীভাবে কোনও টেবিলের কাঠামো অনুলিপি করতে পারি (ব্যাকআপ ব্যবহার না করে)?
আমি প্রাথমিকভাবে এটি ম্যানুয়ালি করতে চাইছি, তবে যদি এটি সম্ভব না হয় তবে আমি কোনও সমাধান গ্রহণ করব।
উত্তর:
আপনি অবশ্যই ইউআই ব্যবহার করে তুলনামূলকভাবে সহজ কোনও টেবিলের স্ক্রিপ্ট করতে পারেন:
এটি একটি CREATE TABLEস্ক্রিপ্ট আউটপুট দেবে এবং আপনাকে কেবল নতুন নামের সাথে পুরানো নামটি সন্ধান করতে হবে এবং প্রতিস্থাপন করতে হবে (এবং যাচাই করুন যে নতুন নামের কোনও বস্তু ইতিমধ্যে বিদ্যমান নেই)।
তবে আপনি যদি এটি স্বয়ংক্রিয় করার চেষ্টা করছেন (যেমন কোডে টেবিল স্ক্রিপ্ট তৈরি করুন), এটি কিছুটা জটিল more উপরের স্ক্রিপ্টিং বিকল্পটি কেবল CREATE TABLEমেটাডেটার একক অবস্থান থেকে পুরো ডিডিএলকে টানবে না; এটি শেষ CREATE TABLEস্ক্রিপ্টটি তৈরি করতে কোডের পর্দার আড়ালে পুরো জাদুতে কাজ করে (আপনি প্রোফাইলারটি এটির ডেটা কোথায় তা দেখতে ব্যবহার করতে পারেন তবে এটি কীভাবে এটি একত্রিত করে তা আপনি দেখতে পারবেন না)। আমি এর জন্য একটি বিকল্প প্রস্তাব করেছি:
http://connect.microsoft.com/SQLServer/feedback/details/273934
তবে এটি খুব কম ভোটের সাথে মিলিত হয়েছিল এবং মাইক্রোসফ্ট খুব তাড়াতাড়ি গুলি করে মারা হয়েছিল। স্কিমা উত্পন্ন করার জন্য ২ য় পক্ষের সরঞ্জামটি ব্যবহার করা আপনার পক্ষে আরও সার্থক হতে পারে ( আমি এই সম্পর্কে ব্লগ করেছি )।
এসকিউএল সার্ভার ২০১২-তে নতুন নতুন মেটাডেটা ফাংশন রয়েছে যা আপনাকে ২০০৫, ২০০৮ এবং ২০০৮ আর 2 এর যে কাজটি করতে হবে তার থেকে অনেক বেশি এগিয়ে যাওয়ার সুযোগ দেয়, মেটাডেটা থেকে কলামের তথ্য একসাথে ছড়িয়ে দেয় (যার মধ্যে প্রচুর ক্যাভেট রয়েছে, উদাহরণস্বরূপ যদি এটি হয় তবে দশমিক আপনাকে নির্ভুলতা / স্কেল যোগ করতে হবে, যদি [n [var [চর]] আপনাকে দৈর্ঘ্যের স্পেসিফিকেশন যোগ করতে হয়, যদি এন [ভার্] চর আপনাকে অর্ধেকের মধ্যে সর্বোচ্চ_ দৈর্ঘ্য কাটাতে হয়, যদি এটি আপনাকে একটি ম্যাক্স হয় -1 ম্যাক্স, ইত্যাদি এ পরিবর্তন করুন)। এসকিউএল সার্ভারে 2012 এই অংশটি কিছুটা সহজ:

-- Creates a copy of a table with optionally all indexes and constraints depending on parameters
-- Updated by : Brent Willis
-- Date Updated : 09-11-2019
-- Changes: Added the ability to create a table with clustered index and constraints only or to
-- CREATE just the non-clustered indexes. This is helpful so a table can be created,
-- loaded then non-clusted indexes added so it can them be swapped into a partitioned
-- table with freshly created indexes to lower fragmentation.
--
-- Also fixed an issue when a unique index was defined the index resulting table was not unique.
