How to add prefix of all tables in mysql

Question

How can I add prefix to all tables in mysql using query.

For example:

I need to add \"dr_\" in all tables which are available in mysql database.

Answer 1

Add a prefix to all of your database tables.

Supposing that your database was called "my_database" and the prefix you want to add is "my_prefix", execute the following query:

SELECT Concat('ALTER TABLE ', TABLE_NAME, ' RENAME TO my_prefix_', TABLE_NAME, ';') FROM information_schema.tables WHERE table_schema = 'my_database'

Your result set will be a bunch of queries that you can copy and paste into your favorite MySQL editor (Sequel Pro, phpMyAdmin, whatever). Just paste those in and execute, and you're all done.
