Trigger creation context of table `%s`.`%s` is invalid
MySQL throws error 1604 with message "Trigger creation context of table db.tbl is invalid" when the metadata stored inside a trigger definition no longer matches the table's current environment. The discrepancy can involve SQL mode, definer, character set, or collation recorded at trigger creation time.
The error appears while executing DML on the table, running SHOW TRIGGERS, or during backup and replication. Fixing it is critical because invalid triggers are skipped, leading to data integrity issues.
Each trigger stores the SQL mode, definer user@host, and default character set present at creation. When those settings change or the definer account is removed, MySQL cannot guarantee identical semantics and flags the trigger as invalid, raising error 1604.
Altering the table charset, changing GLOBAL sql_mode, or restoring a dump on a server with different defaults frequently breaks the stored context and surfaces this error.
Safest fix is recreating the affected trigger under the intended definer, SQL mode, and character set. First capture the body with SHOW CREATE TRIGGER, then DROP TRIGGER and run a fresh CREATE TRIGGER statement.
If the original definer no longer exists, create that account temporarily or replace the DEFINER clause with a valid privileged user before recreating the trigger. Always test in staging.
After migrating a database, triggers reference the old server's strict sql_mode, so UPDATE statements fail. Set sql_mode to match or recreate the trigger immediately.
Replication stops because a trigger uses a definer absent on the replica. Create the user on the replica or modify the trigger definition, then resume replication.
Standardize GLOBAL and SESSION sql_mode across environments and track them in configuration management. Use explicit character set clauses when creating tables and triggers.
Deploy triggers through version control so recreating them in CI pipelines is simple. Audit triggers regularly with SHOW TRIGGERS and flag any whose definer lacks a valid account.
Error 1445 ER_TRG_CANT_CHANGE_ROW fires when a before trigger tries to modify the same row. Error 1227 ER_SPECIFIC_ACCESS_DENIED_ERROR appears when the definer lacks required privileges. Both can follow environment changes and are fixed by reviewing trigger logic and user rights.
The trigger was created under STRICT_TRANS_TABLES or other modes that have since changed, invalidating its context.
The user specified in the DEFINER clause was deleted or privileges were revoked, so MySQL cannot execute the trigger.
Altering the table or database character set after trigger creation causes a mismatch with the stored metadata.
Dumping a database on one MySQL version and importing to another with different defaults often breaks trigger contexts.
Raised when a before trigger tries to change the same row. Review trigger logic to fix.
Occurs when the trigger definer lacks required privileges. Grant proper rights or change definer.
Appears during CREATE or ALTER DEFINER statements when the user does not exist. Create the user first.
Dropping the table removes its triggers, so the error disappears, but you lose data logic. Recreating triggers is safer.
No direct setting bypasses the context check. Recreate the trigger or align sql_mode to resolve.
mysqldump exports triggers verbatim. Importing to a different environment can still cause error 1604 until triggers are recreated.
Galaxy surfaces invalid triggers in the schema browser and lets you edit and recreate them quickly in its IDE, reducing downtime.
