mybatis的原因！！！！！
数据库这个样子
在postman中调用接口：SQL
select * from T_TRAIN_MARSHALLING where TRAIN_NUM is null and PRE_TRAIN_NUMBER is null and RECEIVE_SEND=#{RECEIVE_SEND}
union all
select * from T_TRAIN_MARSHALLING where TRAIN_NUM = #{TRAIN_NUM} and PRE_TRAIN_NUMBER is null
查询结果：
在SQLserver中的测试如下：
然后就开始找原因，解决方案就是加trim，这个很恶心，或者mybaits下就不要用char了
select * from T_TRAIN_MARSHALLING where TRAIN_NUM is null and PRE_TRAIN_NUMBER is null and trim(RECEIVE_SEND)=#{RECEIVE_SEND}
union all
select * from T_TRAIN_MARSHALLING where TRAIN_NUM = #{TRAIN_NUM} and PRE_TRAIN_NUMBER is null
