MySQL Error 4090: Assigned GTID_NEXT Blocks Command
Description
This error indicates that MySQL cannot execute a given command because the `@@SESSION.GTID_NEXT` variable is explicitly set to a specific GTID (e.g., 'UUID:NUMBER'). MySQL enforces this restriction to maintain GTID consistency, particularly in replication scenarios, preventing operations that could disrupt the GTID sequence. It typically occurs when attempting DDL or DML statements after manual GTID assignment.
Error Message
Can't execute the given command when @@SESSION.GTID_NEXT == 'UUID:NUMBER'.
Known Causes
3 known causesManual GTID_NEXT Assignment
The `@@SESSION.GTID_NEXT` variable has been explicitly set by a user or script to a specific GTID value, which prevents subsequent command execution.
Attempting Restricted Operations
Certain DDL or DML statements are not permitted when `@@SESSION.GTID_NEXT` is assigned, as MySQL requires strict GTID sequence integrity for these operations.
Unreset Session State
A previous administrative task or script might have set `@@SESSION.GTID_NEXT` and failed to reset it, leaving the current session in a restricted state.
