I need to set UNIQUE_CHECKS to 0 for a specific PHP file that has bulk insert, I just wanna know how long does it remain 0? Do I have to set UNIQUE_CHECKS to 1 after the bulk insert manually or it will automatically be changed to the default GLOBAL variable value?
UNIQUE_CHECKSis a MySQL variable which is set per connection. The moment the connection is closed (normally at the end of the script or when using the appropriate MySQL client command), the setting has ended it’s lifetime.Next time a new connection starts, the value from MySQL configuration is taken again.
