使用mybatis的Criteria 查询、条件过滤用法

1、如果业务查询中,有的条件要用括号()括起来达到想要的效果,如:第2个and后面的条件要括起来
【此业务大概是这样的,即要查他自己所有的,还要查别人share_status=0的,(别人share_status=1的不能查出来)】
select * from tb_examination where 1=1 and create_user_id in ( SELECT id from nsrep_identity.identity_user where company_id = 'xxxxx' ) and (
create_user_id = 'xxxxx' and share_status = 1 or share_status = 0
)
2、用mybatis的Criteria写法怎么查?
那么要使用两个critera,如下:
Example example = new Example(Examination.class); Example.Criteria1 criteria = example.createCriteria(); criteria1.andIn("createUserId", userIds); Example.Criteria criteria2 = example.and(); criteria2.andEqualTo("createUserId", userId); criteria2.andEqualTo("shareStatus", 1); criteria2.orEqualTo("shareStatus", 0);
上面的criteria代码,相当于sql:where (criteria1的条件) and (criteria2的条件)
select * from tb_examination where 1=1 ( and create_user_id in ( SELECT id from nsrep_identity.identity_user where company_id = 'xxxxx' ) ) and ( create_user_id = 'xxxxx' and share_status = 1 or share_status = 0 )
注意的问题:and share_status = 1 or share_status = 0 这里1和0顺序写反了,结果完全不一样,调了老子半天才发现
。
