工人的每个

Question

天

第一和最后的检查，我需要每个员工的第一个入住和最后退房每一天的列表...

我得到的结果，从下面的查询什么只是，每天一个数据......

SELECT 
    p.prsnCode [Sicil No] 
    ,p.[prsnName1] 
    ,p.[prsnName2] 
    ,t.[ioTransactionDate] 

     ,[Giris/Cikis] = (
    case 
    when [ioStatus] = 0 then 'Giris' 
    when [ioStatus] = 1 then 'Cikis' 
    else 'Uzaya Gitti' end) 


    FROM [IOTransaction] t 

    left join dbo.Person p on t.ioPrsnRefId = p.prsnRefId 

    where t.[ioTransactionDate] = (select MIN(m.[ioTransactionDate]) from IOTransaction m 
            where m.ioPrsnRefId = t.ioPrsnRefId and CAST(m.[ioTransactionDate] AS DATE) = CAST(t.[ioTransactionDate] AS DATE) 
              group by m.ioPrsnRefId) 
     OR t.[ioTransactionDate] = (select MAX(m.[ioTransactionDate]) from IOTransaction m 
            where m.ioPrsnRefId = t.ioPrsnRefId and CAST(m.[ioTransactionDate] AS DATE) = CAST(t.[ioTransactionDate] AS DATE) 
              group by m.ioPrsnRefId) 

group by t.ioPrsnRefId, prsnCode, prsnName1 , prsnName2, t.[ioTransactionDate], ioStatus 


    ORDER BY P.prsnCode 

我也尝试这种group by m.ioPrsnRefId, CAST(m.[ioTransactionDate] AS DATE)添加到where子句，但它给错误...（子查询返回多个值。）

试试这个。如果我做了一些不正确的假设，我已经包含了样本表和我使用的数据。

create table person 
(
    prsnRefId int, 
    prsnCode varchar(50), 
    prsnName1 varchar(50), 
    prsnName2 varchar(50) 
); 

create table IOTransaction 
(
    ioPrsnRefId int, 
    ioTransactionDate datetime, 
    ioStatus int 
); 

insert into person values(1,'code1','Bob','Carolgees'); 
insert into person values(2,'code2','Diana','Dors'); 

insert into IOTransaction values(1,'01-jan-2016 09:00:00',0); 
insert into IOTransaction values(1,'01-jan-2016 12:00:00',1); 
insert into IOTransaction values(1,'01-jan-2016 13:00:00',0); 
insert into IOTransaction values(1,'01-jan-2016 18:00:00',1); 
insert into IOTransaction values(1,'02-jan-2016 09:01:00',0); 
insert into IOTransaction values(1,'02-jan-2016 12:01:00',1);

insert into IOTransaction values(2,'01-jan-2016 17:45:00',1); 
insert into IOTransaction values(2,'02-jan-2016 08:31:00',0); 
insert into IOTransaction values(2,'02-jan-2016 12:31:00',1); 
insert into IOTransaction values(2,'02-jan-2016 13:31:00',0); 
insert into IOTransaction values(2,'02-jan-2016 17:46:00',1);

    from IOTransaction 
    where ioStatus = 1 
) 
SELECT p.prsnCode [Sicil No] 
    ,p.[prsnName1] 
    ,p.[prsnName2] 
    ,t.[ioTransactionDate] 
    ,[Giris/Cikis] = (

    when [ioStatus] = 0 then 'Giris' 
    when [ioStatus] = 1 then 'Cikis' 
    else 'Uzaya Gitti' end)
