MySQL Error 1679: Modifying binlog_format in Transaction
Description
This error occurs when you attempt to change the `@@session.binlog_format` system variable while an active transaction is in progress within your MySQL session. MySQL prevents this modification to maintain data consistency and ensure the integrity of binary logging and replication. It indicates that a critical logging parameter cannot be altered during a transactional state.
Error Message

Known Causes
3 known causesExplicit Transaction Active
You executed a `SET @@session.binlog_format` statement after initiating a transaction with `START TRANSACTION` or `BEGIN` that has not yet been committed or rolled back.
Implicit Transaction Pending
An earlier DDL statement (e.g., `CREATE TABLE`, `ALTER TABLE`) or a specific operation might have implicitly started a transaction that is still active in your session.
Conflicting Application Logic
Your application or script attempts to modify the `binlog_format` within the scope of an ongoing, uncommitted database transaction.
