In Access I have a table, where I enter the times I began and finished work for each day. Logically, these two numbers allow you to calculate how long you worked. In another Table I have currently four records, defining how long the lunch break has to be on a specific day, based on how long I worked that day, something like this
Minimum work time; Minimum break
0:00; 0:00
5:31; 0:15
7:01; 0:30
9:01; 1:00
In Excel I can use the Vlookup, set to work with approximate times. For example, if one day the duration was 7:42, the Vlookup would return "0:30", going to the closest lower value, 7:01, and returning 0:30. Is there a function in the formula editor in the query window of Access to solve this problem or does Access just lack this possibility? I'm just very curious about that.
Use a subquery to look up the break time:
SELECT
TableWork.Id,
TableWork.BeginTime,
TableWork.FinishTime,
CDate(FinishTime - BeginTime) AS WorkTime,
(Select Top 1
[Minimum break]
From
TableBreak
Where
[Minimum work time] <= ([FinishTime] - [BeginTime])
Order By
[Minimum work time] Desc) AS BreakTime,
CDate([WorkTime] - [BreakTime]) AS NetTime
FROM
TableWork
ORDER BY
TableWork.Id;
