| JdbcType | NVARCHAR | ||
| JdbcType | OTHER | ||
| JdbcType | REAL | REAL | REAL |
| JdbcType | SMALLINT | SMALLINT | SMALLINT |
| JdbcType | STRUCT | ||
| JdbcType | TIME | TIME | |

注意到, MyBatis的JdbcType中部分没有对应到Oracle和Mysql的数据类型中(或许由于自己遗漏)，不过不用担心，后续大家碰到再具体分析；同时上述对应关系不一定是一一对应，请大家了解。
大家主要掌握基本的数字、时间、字符串就足以应对日常开发了。
