如何查看mysql支持的存储引擎
作者:zhanhailiang 日期:2013-03-07
要想找出你的服务器支持哪个存储引擎,执行下面的语句:
mysql> SHOW ENGINES\G*************************** 1. row *************************** Engine: FEDERATED Support: NO Comment: Federated MySQL storage engineTransactions: NULL XA: NULL Savepoints: NULL*************************** 2. row *************************** Engine: MRG_MYISAM Support: YES Comment: Collection of identical MyISAM tablesTransactions: NO XA: NO Savepoints: NO*************************** 3. row *************************** Engine: MyISAM Support: YES Comment: MyISAM storage engineTransactions: 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: MEMORY Support: YES Comment: Hash based, stored *************************** 6. row *************************** Engine: CSV Support: YES Comment: CSV storage engineTransactions: NO XA: NO Savepoints: NO*************************** 7. row *************************** Engine: ARCHIVE Support: YES Comment: Archive storage engineTransactions: NO XA: NO Savepoints: NO*************************** 8. row *************************** Engine: PERFORMANCE_SCHEMA Support: YES Comment: Performance SchemaTransactions: NO XA: NO Savepoints: NO*************************** 9. row *************************** Engine: InnoDB Support: DEFAULT Comment: Supports transactions, row-level locking, and foreign keysTransactions: YES XA: YES Savepoints: YES9 rows in set (0.00 sec)
还可以使用下面的语句代替SHOW ENGINES,并检查你感兴趣的存储引擎的变量值:
mysql> SHOW VARIABLES LIKE "have%";+----------------------+----------+| Variable_name | Value |+----------------------+----------+| have_compress | YES || have_crypt | YES || have_csv | YES || have_dynamic_loading | YES || have_geometry | YES || have_innodb | YES || have_ndbcluster | NO || have_openssl | DISABLED || have_partitioning | YES || have_profiling | YES || have_query_cache | YES || have_rtree_keys | YES || have_ssl | DISABLED || have_symlink | YES |+----------------------+----------+14 rows in set (0.00 sec)
