MariaDB Error 1686: Changing Binlog Flag in Stored Routines
Description
This error indicates an attempt to modify the `binlog_direct_mode` flag or similar binary logging behavior within the scope of a stored function or trigger. MariaDB restricts such operations inside these routines to ensure data consistency and predictable binary log contents. It typically occurs when SQL statements that alter session variables related to binary logging are executed within a function or trigger definition.
Error Message
Cannot change the binlog direct flag inside a stored function or trigger
Known Causes
3 known causesDirect Binlog Mode Alteration
The most common cause is an explicit `SET SESSION binlog_direct_mode` statement being executed within the body of a stored function or trigger.
Legacy Code or Migration
This can occur when migrating code from older database versions or other systems where similar operations within stored routines might have been permitted, but are restricted in current MariaDB versions.
Contextual Restrictions Misunderstanding
Developers might be unaware of MariaDB's limitations regarding modifying global or session-specific binary logging parameters within the isolated context of stored functions and triggers.
