Does MySQL foreign_key_checks affect the entire database?

Question

When I execute this command in MySQL:

SET FOREIGN_KEY_CHECKS=0;

Does it affect the whole engine or it is only my current transaction?

Answer 1

I had the same error when I tried to migrate Drupal database to a new local apache server(I am using XAMPP on Windows machine). Actually I don't know the meaning of this error, but after trying steps below, I imported the database without errors. Hope this could help:

Changing php.ini at C:\xampp\php\php.ini

max_execution_time = 600
max_input_time = 600
memory_limit = 1024M
post_max_size = 1024M

Changing my.ini at C:\xampp\mysql\bin\my.ini

max_allowed_packet = 1024M
