mybatis在更新数据或者插入数据为空的时候必须指定jdbcType类型
1：传入的参数是对象类型
User user =new User(); INSERT INTO t_user ( id, uid, sn, EXPIRY_DATE, STUS, REASON, REMARK, )VALUES( SEQ_user.NEXTVAL, #{uid,jdbcType=VARCHAR}, #{sn,jdbcType=VARCHAR}, #{expiryDate,jdbcType=DATE}, #{stus,jdbcType=VARCHAR}, #{reason,jdbcType=VARCHAR}, #{remark,jdbcType=VARCHAR}, )
如果传入的参数是此""而不是null值，则可以不用指定jdbcType
如果不设置值或者设置Null则必须指定jdbcType
2:传入参数是一个个传入的
public Integer updateRechargeStus(
@Param("sn") String sn,
@Param("stus") String stus,
@Param("reason") String reason) throws DaoException;
<update id="updateStus">
update t_user t set t.STUS=#{stus},t.REASON = #{reason} where t.sn=#{sn}
</update>
如果传入的sn或者stus都是此""，则不用指定jdbcType;如果传入null则需要指定jdbcType
3:对于查询也是，传入的参数不能为null指
4：拓展
如果把所有的数据类型指定后，传入的null值不会报错，在查找数据的时候就需要注意这些。

最近使用oracle，一些笔记都直接记载到了有道云笔记里面去了，慢慢整理下了。
