mysql8学习手册第五部分 Transactions 事务以及Binlog日志的使用

第五章：Transactions

• Performing transactions

• Isolation levels
• Locking

Transactions should also satisfy Atomicity, Consistency, Isolation, and Durability(ACID) properties.
事务应该保持原子性、一致性、隔离性、永久性

InnoDB , the default storage engine in MySQL, supports transactions whereas MyISAM does not support them.
InnoDB 支持事务，但是MyASIM引擎不支持事务
