MYSQL查询日期时间先入后出

Question

我正在尝试查询 table 名员工，他们的时间是通过门禁控制生成的，以创建出勤工资单。我得到了第一个 IN 和最后一个 Out 的员工。

所以，这是查询：

select * from(select distinct Value as EmployeeNumber ,UID1FirstName+' '+UID1LastName as EmployeeName, convert(varchar(18), dtDate, 1) as LogDate, convert(varchar(18), dtDate, 108) as LogTime, case when ReaderName like '%Entry%' and convert(varchar(18), dtDate, 108) < '13:00:00:00' then 'FirstIN'
when ReaderName like '%Exit%' then 'LastOut' end as Users from Log_Transactions inner join UserCredentials on UID1 = CredentialId inner join UserDefinedFields on HostUserId = UserID where CredentialId = '63' and Event = '2000' and dtDate between '2018-07-01' and '2018-07-13' and FieldNo = '1') as Userssssss PIVOT ( max(LogTime)FOR [Users] IN ([FirstIN], [LastOut])) AS Time1 GROUP BY EmployeeNumber,EmployeeName,FirstIN,LastOut,LogDate order by LogDate asc

下面是查询结果：（我得到了Employee的LastOut但是我没有正确得到日期和时间的FirstIn）

See image result here

如果我在第一个 IN 的 table 上获得正确的数据，它会显示员工的第一个 IN 数据，而我在上面显示的第一个查询中没有获得正确的数据。请帮忙。因此，这是选择她第一个 IN 的员工的所有交易的结果。

Answer 1

create table Door ( Employee varchar(60), Direction varchar(5), Stamp datetime )

go

insert into Door (Employee, Direction, Stamp ) values
( 'Fred', 'Entry', '2018-01-10 08:00:00.000' ),
( 'Fred', 'Exit',  '2018-01-10 08:30:00.000' ),
( 'Fred', 'Entry', '2018-01-10 11:00:00.000' ),
( 'Fred', 'Exit',  '2018-01-10 14:00:00.000' ),
( 'Fred', 'Entry', '2018-01-10 14:20:00.000' ),
( 'Fred', 'Exit',  '2018-01-10 16:00:00.000' ),
( 'Fred', 'Entry', '2018-01-11 08:15:00.000' ),
( 'Fred', 'Exit',  '2018-01-11 08:45:00.000' ),
( 'Fred', 'Entry', '2018-01-11 17:00:00.000' ),
( 'Fred', 'Exit',  '2018-01-11 18:00:00.000' ),

( 'Mary', 'Entry', '2018-01-10 07:00:00.000' ),
( 'Mary', 'Exit',  '2018-01-10 09:30:00.000' ),
( 'Mary', 'Entry', '2018-01-10 11:15:00.000' ),
( 'Mary', 'Exit',  '2018-01-10 15:45:00.000' ),

with 

-- Break the timestamp into separate Date and Time
DoorA as 
( select Employee, Direction, 
         cast(Stamp as date) as DoorDate, 
         cast(Stamp as time) as DoorTime from Door ),

-- Group together records for each Employee and Date.
-- This will give the earliest and latest Entry,
-- as well as earliest and latest Exit
DoorB as 
( select Employee, Direction, DoorDate, 
         min(DoorTime) as First, 
         max(DoorTime) as Last from DoorA 
         group by Employee, Direction, DoorDate ),

-- Pull out the MIN values for the Entry records,
-- together with the MAX values for the Exit records.
DoorC as

         'First Entry' as FirstOrLast,

  select Employee,DoorDate,
         'Last Exit'   as FirstOrLast,
