markdown [mybatis参考]关于mybatis #mybatis的一些片段

- about date jdbcType
  ```
  #{beginDate,jdbcType=DATE} (no time of the day), or
  #{beginDate,jdbcType=TIMESTAMP} (if you need to include the time of the day).
  ```

And the Java parameter you want to apply should be of type:
  ```
  java.sql.Date (date without time)
  java.sql.Timestamp (timestamp)
  java.util.Date (date and time).
  ```

- the Greater Than/Equal Operator and the Less Than/Equal Operators:
  ```
  ROWNUM >= 20
  ROWNUM <= 20
  ```
