MySQL Error 1568: Transaction In Progress Modification
Description
MySQL Error 1568 indicates that an attempt was made to change a transaction characteristic, such as the `AUTOCOMMIT` setting or `TRANSACTION ISOLATION LEVEL`, while an active transaction was already in progress. MySQL prevents these changes mid-transaction to maintain data integrity and consistent behavior within the current transaction scope.
Error Message
Transaction characteristics can't be changed while a transaction is in progress
Known Causes
3 known causesChanging AUTOCOMMIT Mid-Transaction
This occurs when an attempt is made to alter the `AUTOCOMMIT` setting (e.g., `SET AUTOCOMMIT = 0`) while an explicit transaction (started with `START TRANSACTION` or `BEGIN`) is still active.
Altering Isolation Level Mid-Transaction
Trying to change the `TRANSACTION ISOLATION LEVEL` (e.g., using `SET TRANSACTION ISOLATION LEVEL SERIALIZABLE`) after a transaction has already begun will trigger this error.
Modifying Access Mode Mid-Transaction
Changing the transaction access mode (e.g., `READ ONLY` or `READ WRITE` via `SET TRANSACTION READ ONLY`) after a transaction has started is not permitted by MySQL.
