MySQL Error 1228: Incorrect Scope for Variable Setting
Description
This error occurs when you attempt to modify a MySQL system variable using the `SET GLOBAL` command, but the specified variable is strictly a `SESSION` variable. `SESSION` variables are confined to the current client connection and cannot be altered globally for the entire server instance.
Error Message
Variable '%s' is a SESSION variable and can't be used with SET GLOBAL
Known Causes
3 known causesMisunderstanding Variable Scope
Users often confuse the distinct scopes of global and session-level variables, leading them to attempt universal changes for variables designed for individual connection settings.
Defaulting to SET GLOBAL
Executing `SET GLOBAL` for all variable modifications without prior verification of the variable's actual scope, incorrectly assuming all variables can be set globally.
Incorrect Persistence Strategy
An attempt to make a variable change permanent across server restarts by using `SET GLOBAL`, despite the variable being inherently session-specific and not intended for global persistence.
