05-MySQL5.6所支持的存储引擎

4.3.1 MySQL5.6所支持的存储引擎

MySQL提供了多个不同的存储引擎，包括处理事务安全表的引擎和处理非事务安全表的引擎。在MySQL中，不需要在整个服务器中使用同一种存储引擎，针对具体要求，可以对每一个表使用不同的存储引擎。MySQL 5.6支持的存储引擎有：InnoDB，MyISAM，Memory，Merge，Archive，Federated，CSV，BLACKHOLE等。可以使用SHOW ENGINES语句查看系统所支持的引擎类型，执行结果如下。

mysql> SHOW ENGINES \G 1.row Engine: FEDERATED Support: NO Comment: Federated MySQL storage engine Transactions: NULL XA: NULL Savepoints: NULL 2.row Engine: MRG_MYISAM Support: YES Comment: Collection of identical MyISAM tables Transactions: NO XA: NO Savepoints: NO 3.row Engine: MyISAM Support: YES Comment: MyISAM storage engine Transactions: NO XA: NO Savepoints: NO 4.row Engine: BLACKHOLE Support: YES Comment: /dev/null storage engine (anything you write to it disappears) Transactions: NO XA: NO Savepoints: NO 5.row Engine: CSV Support: YES Comment: CSV storage engine Transactions: NO XA: NO Savepoints: NO 6.row Engine: MEMORY Support: YES Comment: Hash based, stored in memory, useful for temporary tables Transactions: NO XA: NO Savepoints: NO 7.row Engine: ARCHIVE Support: YES Comment: Archive storage engine Transactions: NO XA: NO Savepoints: NO 8.row Engine: InnoDB Support: DEFAULT Comment: Supports transactions, row-level locking, and foreign keys Transactions: YES XA: YES Savepoints: YES 9.row Engine: PERFORMANCE_SCHEMA Support: YES Comment: Performance Schema Transactions: NO XA: NO Savepoints: NO 9 rows in set (0.01 sec)

Support列的值表示某种引擎是否能使用：YES表示可以使用，NO表示不能使用，DEFAULT表示该引擎为当前默认存储引擎。
