写在前面

一、Mysql

和存储引擎有关

CREATE TABLE t1 (i INT) ENGINE = INNODB;
CREATE TABLE t2 (i INT) ENGINE = MYISAM;
-- Simple table definitions can be switched from one to another.
CREATE TABLE t3 (i INT) ENGINE = CSV;
CREATE TABLE t4 (i INT) ENGINE = MEMORY;
CREATE TABLE t5 (i INT) ENGINE = ARCHIVE;      

只生成了四个表，CSV的存储引擎加载不正确，

二、Oracle
