mybatis返回多个map结果

• 如果返回一条结果，xml直接这样写：

    select
    t1.invest_id                      ,
    cast(t1.modify_time AS DATE) modify_time
    from t_c_wh_redeeminfo t1
    where 1=1
    and t1.invest_id =#{investId}

dao中：

Map searchncomedateByInvestID(investId);

• 如果返回多条结果，xml这样写：

        
        



    select
    t1.invest_id                      ,
    cast(t1.modify_time AS DATE) modify_time
    from t_c_wh_redeeminfo t1
    where 1=1
    and t1.invest_id in
    
        #{investId}
    

dao中：

List> searchncomedateByInvestID(List preinvestList);
