Truncate all tables (most of which have constraints). How to temporarily drop them

Question

I have a development database (MYSQL) which I would like to load with fresh data at some point. I would like to delete the content of all tables. What is the best way, as autom

Answer 1

Here's what I do from the command prompt:

 mysql -Nse 'show tables' DATABASE_NAME | while read table; do mysql -e "SET FOREIGN_KEY_CHECKS = 0; TRUNCATE table $table" DATABASE_NAME; done

Problem is, if you require authentication, you will need to add a -u YOUR_USERNAME -pYOURPASSWORD after both mysql commands.

If you don't want to enter your password at the command prompt (I don't ever), then you'll need to copy and paste the password after every prompt, which may be several times depending on the number of tables.
