示例

SHOW ENGINES;
+--------+---------+------------------------------------------------------------+--------------+------+------------+ | Engine | Support | Comment | Transactions | XA | Savepoints | +--------+---------+------------------------------------------------------------+--------------+------+------------+ | InnoDB | DEFAULT | Supports transactions, row-level locking, and foreign keys | YES | YES | YES | +--------+---------+------------------------------------------------------------+--------------+------+------------+ 1 row in set (0.00 sec)

MySQL 兼容性

  • SHOW ENGINES 语句始终只返回 InnoDB 作为其支持的引擎。但 TiDB 内部通常使用 TiKV 作为存储引擎。
