Hi Gopal,
According to your description, it seems that the output needn’t include the row when EmpID=2. Because the DateTime for it in Table1 doesn’t included between FromDate column and ToDate column. After testing the issue in my environment, we can refer to the
query like below to achieve your requirement:
SELECT time.*,cost.EmpID,cost.Rate,(time.HoursSpend * cost.Rate)as [Total (HoursSond x Rate)]
FROM [Time sheet] as time
INNER JOIN
[cost table]as cost
ON time.EmpID = cost.EmpID
AND time.DateTime BETWEEN cost.FromDate AND cost.ToDate
If there are any other questions, please feel free to ask.
Thanks,
