MS Access SQL 查询出勤时间

Question

HI,

I'm doing a project which involves time and attendance management. When I download data from the biometric reader, I got the records in the following format,

Lunch Break & Work Time Problem

Attendance Log Table Name: dbo_CHECKINOUT The user Table name is: dbo_USERINFO

SELECT t.userid, dbo_USERINFO.NAME, DateValue(t.checktime) AS [date], 
Max(IIf(t.counter=0,t.checktime,Null)) AS Log_In, 
Max(IIf(t.counter=1,t.checktime)) AS LB_Out, 
Max(IIf(t.counter=2,t.checktime,Null)) AS LB_In, 
Max(IIf(t.counter=3,t.checktime)) AS Log_Out, 
Format((Log_In-LB_Out)+(LB_In-Log_Out),"hh:nn:ss") AS WorkTime, 
Format(LB_In-LB_Out,"hh:nn:ss") AS LunchBreak
FROM (
    SELECT t.*, 
      (select count(*) from dbo_CHECKINOUT where userid = t.userid and datevalue(checktime) = datevalue(t.checktime) and checktime < t.checktime) AS [counter] FROM dbo_CHECKINOUT AS t)  AS t INNER JOIN dbo_USERINFO ON t.USERID=dbo_USERINFO.USERID
GROUP BY t.userid, dbo_USERINFO.NAME, DateValue(t.checktime);

I want to show the above records as follows, (the Log_In, LB_Out, LB_In, Log_Out, WorkTime and LunchBreak are based on 'time') Someone from StackOverFlow helped me out to make this query

userid      date         Log_In        LB_Out        LB_In       Log_Out    WorkTime    LunchBreak
1           16-Feb-20   11:10:10 AM   7:51:57 PM                
1           17-Feb-20   11:28:17 AM                 
2           16-Feb-20   9:57:48 AM    1:58:19 PM    2:33:39 PM  9:29:29 PM  10:56:21     00:35:20

4           16-Feb-20   10:36:01 AM   9:29:46 PM                
4           17-Feb-20   10:28:54 AM                 
5           16-Feb-20   9:33:08 AM    1:57:46 PM    2:48:26 PM  9:29:25 PM  11:05:37     00:50:40
5           17-Feb-20   9:31:47 AM  

Results:

Now the problem is, as you can see Userid:1 & Userid: 4 doesn't have a LunchBreak. So their 1st log would be Log_In & 2nd Log would be as a Log_Out & total work time would be between 1st(Log_In) & 2nd(Log_Out).

Please help to make this possible for me.

This fancy query will return the lunch breaks:

SELECT 
    dbo_UserInfo.UserId, 
    DateValue([CheckTime]) AS [Date], 
    TimeValue(Min([CheckTime])) AS LogIn, 

    (Select Max(TimeValue(T.CheckTime)) 
    From dbo_UserInfo As T 
    Where T.UserId = dbo_UserInfo.UserId 
    And DateValue(T.CheckTime) = DateValue(dbo_UserInfo.CheckTime) 
    And T.CheckTime >
        (Select Min(S.CheckTime) 
        From dbo_UserInfo As S 
        Where S.UserId = dbo_UserInfo.UserId 
        And DateValue(S.CheckTime) = DateValue(dbo_UserInfo.CheckTime))) As LogOut,

    (Select Min(TimeValue(T.CheckTime)) 
    From dbo_UserInfo As T 
    Where T.UserId = dbo_UserInfo.UserId 
    And DateValue(T.CheckTime) = DateValue(dbo_UserInfo.CheckTime)
    And T.CheckTime > 
        (Select Min(S.CheckTime) 
        From dbo_UserInfo As S 
        Where S.UserId = dbo_UserInfo.UserId 
        And DateValue(S.CheckTime) = DateValue(dbo_UserInfo.CheckTime))
    And T.CheckTime <
        (Select Max(S.CheckTime) 
        From dbo_UserInfo As S 
        Where S.UserId = dbo_UserInfo.UserId 
        And DateValue(S.CheckTime) = DateValue(dbo_UserInfo.CheckTime))
    Having Count(*) > 1) As LBIn,

    (Select Max(TimeValue(T.CheckTime)) 
    From dbo_UserInfo As T 
    Where T.UserId = dbo_UserInfo.UserId 
    And DateValue(T.CheckTime) = DateValue(dbo_UserInfo.CheckTime) 
    And T.CheckTime > 
        (Select Min(S.CheckTime) 
        From dbo_UserInfo As S 
        Where S.UserId = dbo_UserInfo.UserId 
        And DateValue(S.CheckTime) = DateValue(dbo_UserInfo.CheckTime))
    And T.CheckTime <
        (Select Max(S.CheckTime) 
        From dbo_UserInfo As S 
        Where S.UserId = dbo_UserInfo.UserId 
        And DateValue(S.CheckTime) = DateValue(dbo_UserInfo.CheckTime))
    Having Count(*) > 1) As LBOut
FROM 
    dbo_UserInfo
GROUP BY 
    dbo_UserInfo.UserId, 
    DateValue([CheckTime]);

From this you can easily calculate the work hours.
