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

In case of using Mysql query browser, SET FOREIGN_KEY_CHECKS=0; does not have any impact in version 1.1.20. However, it works fine on Mysql query browser 1.2.17
