TransactionState changed.
implicit transaction: no autocommit, stmt against transactionable table without START TRANSACTION explicit transaction: START TRANSACTION
read_unsafe: read-operation against non-transactionable table read_trx: read-operation against transactionable table write_unsafe: write-operation against non-transactionable table write_trx: write-operation against transactionable table stmt_unsafe: an unusafe statement was executed like RAND() resultset: some resultset was sent locked_tables: some tables got locked explicitly
'resultset' may be triggered without 'read_trx' and 'read_unsafe' if a 'SELECT' was executed against 'dual' or without table.
