MariaDBERRORCommonSchemaHIGH confidence
Native table structure is wrong for this version
Production Risk
High — queries against system tables may fail until upgrade is completed.
What this means
A native MySQL system table (e.g., performance_schema or mysql schema) has an unexpected structure, usually because the server was upgraded without running mysql_upgrade.
Why it happens
- 1The server was upgraded but mysql_upgrade or the upgrade script was not run.
- 2System table definitions are out of date relative to the server version.
How to reproduce
trigger — this will error
trigger — this will error
-- Accessing a performance_schema table after a partial upgrade
expected output
ERROR 1631 (HY000): Table 'performance_schema.events_waits_current' has wrong structure.
Fix
Run mysql_upgrade
Run mysql_upgrade
mysql_upgrade -u root -p
Why this works
mysql_upgrade updates system table structures to match the current server version.
