+  * 參數檔內的 CONFIG_mysql_dump_single_transaction 設為'yes' 來解決 <file>
+:
+# While a --single-transaction dump is in process, to ensure a valid dump file (correct table contents and
+# binary log coordinates), no other connection should use the following statements: ALTER TABLE, CREATE TABLE,
+# DROP TABLE, RENAME TABLE, TRUNCATE TABLE. A consistent read is not isolated from those statements, so use of
+# them on a table to be dumped can cause the SELECT that is performed by mysqldump to retrieve the table
+# contents to obtain incorrect contents or fail.
+CONFIG_mysql_dump_single_transaction='yes'
+# http://dev.mysql.com/doc/refman/5.0/en/mysqldump.html#option_mysqldump_master-data
