… in INNODB_TRX The AUTOCOMMIT setting is a session variable, not a column in the INNODB_TRX table. This was causing 'Unknown column tc.AUTOCOMMIT' errors when querying the process list with transaction detection. Changes: - Removed tc.AUTOCOMMIT from the enhanced process list query - Set autocommit to undefined with explanatory comment - Transaction detection (inTransaction, transactionId) still works correctly The autocommit property was intended to show if a connection has autocommit enabled, but this information is not available from INNODB_TRX or threads. The Process interface already has this as optional, so setting it to undefined is safe and won't break the UI.
