Question : Attendance Report [Access]

Hey,
I recently joined a company and they gave me to work on some old attendance database system.

There are two tables:

Table 1: Staff Details
 - Name
 - Rate_Per_Hour

Table 2: Staff Attendance
 - Name
 - Date
 - Time_IN
 - Time_OUT

Now I want a query which will ask the user to ask the From_Date and To_Date, and the query will calculate the (Total Hour as Time_OUT-Time_IN) * Rate_Per_Hour * (No_of_Days as To_Date-From_Date) with Distinct Names

So it will be displayed as:
Name | Rate_Per_Hour | No_of_Day | Total Income ( Rate_Per_Hour * No_of_Day)

Please help.

Answer : Attendance Report [Access]

Here's a change to parameterize the date:

Select s.Name, s.Rate_Per_Hour, count(*) as No_of_day,
sum(datediff("n",a.Time_in,a.Time_out))/60 * s.rate_per_hour  as Total_Income
From
tblStaff as S inner join tblAttendance as A
on s.Name = a.Name
where a.date between [Enter First Date]  and [Enter Last Date]
group by s.name, s.rate_per_hour


For number of days, the query returns number of days worked.  If you want number of calendar days, then change "count(*)" to "datediff("d", min(a.date), max(a.date))

Your total income calculation does not make sense.  I will gladly sign a 1 year contract at $1 per hour:

number of days * number of hours * rate per hours
 
260 *  2080  *  $1  =   $540,000
