time-and-attendance

问题 We have EP300 device working in server mode. I've implemented Anviz Client application in PHP language in accordance with this protocol description. I have noticed some unexpected stuff in a handler for Get record information (0x3C) command: from time to time, with expected response (with ACK 0xBC), I'm receiving additional lines like this: a500000001df00000e000000000a259a2b6501030000001bd9 . Here is complete "parsed" example of such response: STX | CH | ACK | RET | LEN | DATA | CRC16 --- | -

问题 I have models for Students, Courses, Enrollment, and Attendance. Each course has a different number of days of attendance and I need to be able to edit attendance for those days. I use the following models: public class Student { public int StudentID { get; set; } public string LastName { get; set; } public string FirstMidName { get; set; } public virtual ICollection<Enrollment> Enrollments { get; set; } // To keep track of what classes in which the student is enrolled } public class Course {

问题 I am trying to mark attendance. But I am not able to get the code. My submit should send the input to database for each student. Any suggestion for doing this in better way is welcome. My models.py is as follows It has Employee, Mentor and Student and below is the model where values can be changed. class ClassName(models.Model): class_name = models.CharField(max_length=20) class_date=models.DateField(blank=True, null=True) Mentor= models.ForeignKey(Mentor, related_name='class_mentor') student

问题 I am trying to build an online attendance system where employees sign in and check in daily except for weekends and vacations. so , my idea was to create a daily attendance record as a table in the database. Attendance_date_daily date Employee_ID number(auto generated) Check_in_time time Check_out_time time Attendence_status varchar I am using codeigniter v 3.0.0 it's easy to create a model to get the current time and save it in the database when the user check in/out. but the problem is that

问题 I'm having troubles with writing a query in Microsoft Access. This is how my table looks like and where i want to retrieve data from: I want to write a query that has the following result: As you can see in the first table an employee can check IN and OUT more than 2 times a day. When a employee checks in for the first time the Date/time should be placed in the first colum "CheckIn". When he checks in for the second time the Date/time should be placed in the second column "CheckOut". When he

问题 I have a situation where employees have time-in , and time-out but they are saved into a single column with a type [in =1 ,out = 2] , I need to fetch a single employees time (in-out) in a single row separating with Time-In, Time-Out headers. Here is the example of table that I have , CREATE TABLE #Employee ( empid int, name varchar(20), age int ) CREATE TABLE #TIMEINOUT ( id int, empid int, timeinout datetime, [type] tinyint ) INSERT INTO #Employee values(1,'Benny',35) INSERT INTO #Employee

问题 I'm having difficulties creating a stored procedure that would update rows based on employeeno , checktime and id . Here is my table: I am creating an employee attendance system. Basically we have biometrics finger scanning device to track time and stored it to database but the device was not capable of storing time as checkout it could only be checkin as shown in CheckType column. Now I want to do is to change the Checktype column from I to O Example : If the employee 465-04-01 login at 7:46

问题 I have developed a time monitoring system using fingerprint where the employee will scan his/her finger then it will record the time in and time out. But my problem is logging in and logging out by the employee is unlimited. Is there a solution where the employee can log in and log out ONCE IN A DAY ? Every employee will log in and log out once. Here is my code for my Daily Time Record Form: (Im using visual studio 2010/Digital Persona UareU for my scanner) Imports MySql.Data.MySqlClient

问题 I'm using Fingerprint system to record the IN OUT log of all employee in 4 shifts .Normal shift(08:00-> 17:00) , Shift 1:(06-> 14:00), Shift 2: (14:00-> 22:00) Shift 3:(22:00-> 06:00 tomorrow) . I have 2 main table : When I use the left join : select e.Id as EmpID,CAST(PunchTime as DATE)CheckDate,MIN(cast(a.PunchTime as Time))[TimeIN], max(cast(a.PunchTime as Time))[Time_OUT] from Employee e left join AttLog a on a.EnrollNumber=e.EnrollNumber group by e.Id,CAST(PunchTime as DATE) and when I

问题 We have a sports training camp which is regularly attended by various teams in the city. We have a session per day spanning 2 hrs(9-11 AM) and the time slots could vary for different teams. We would like to capture who attended the training camp on a daily basis. We arrived at the following model to capture attendance. (id, user_id, date, present). Assuming the user attends camp daily (say 30 days in a month), you will see that many records in the database. Assuming we are interested only in
