+         * 5. 非BLOB和TEXT类型在默认未指定NULL、NOT NULL时，默认default null
+         * 6. 在列变更时，不仅变更列名数据类型，同时各个约束中列名也会变更，同时如果约束中包含key length，则变更后的数据类型不应违背key length的约束（有长度的应大于key length；BLOB、TEXT应有key length；可以在存在key length情况下变更为无key length的数据类型，约束中key length忽略；等等）
+         * 7. 字符集每列（char类、eumn、set）默认保存，指定使用指定的，未指定使用表默认的，不受修改表默认字符集而改变，同表默认时，字符集显示省略
+         * 8. 新建表默认innodb引擎，latin1字符集
+         * 9. BLOB、TEXT会根据给定长度自动转换为对应的TINY、MEDIUM，LONG类型，长度和字符集也有关
+         * 10. unique约束在没有指定索引名是非幂等的，会自动以约束索引第一个列名称命名，同时以_2,_3这种形式添加后缀
