mybatis plus or and 合并写法

int count =(new EntityWrapper<HrDeliverEmployContractEntity>()
                .eq("pool_id",()).andNew().lt("contract_start_date",()).or().gt("contract_end_date",())  );

对应的SQL

 
 SELECT COUNT(1)
 FROM hr_deliver_employ_contract
 WHERE (pool_id = 1) AND (contract_start_date < '2018-07-01 00:00:00.0' OR contract_end_date > '2018-10-31 00:00:00.0');
 
 

mybatis plus or使用

1 2 3

QueryWrapper queryWrapper = new QueryWrapper(); queryWrapper .and(wrapper -> (“sim”).or().eq(“sim”, “”)); queryWrapper .eq(“is_delete”, “0”);

  对应SQL

select * from vehicle where name=‘测试' or sim=‘2'
