A script to change all tables and fields to the utf-8-bin collation in MYSQL

Question

Is there a SQL or PHP script that I can run that will change the default collation in all tables and fields in a database?

I can write one

Answer 1

In scripts above all tables selected for convertation (with SHOW TABLES), but a more convenient and portable way to check the table collation before converting a table. This query does it:

SELECT table_name
     , table_collation 
FROM information_schema.tables
