Hi,
Thank a lot for your advise. I really want what you mentioned "
showing that Latness should come from the MIN(time_in) record and Overtime should come from the MAX(time_out) record. If this is correct then we need to do this with two queries and a UNION."

Yet, the sql I written only give me the last lateness and overtime records, how can i use two sql with union to do what I want. Please advise me with example
Thank a lot.



>> emp_id C(4)
>> emp_name C(30)
>> date D
>> in_time T
>> out_time T
>> lateness C(4)
>> overtime C(4)

If this is correct then we need to do this with two queries and a UNION. The SELECT I give you above is going to carry the Latness and Overtime fields from the last record found in the Group By.
