I have one table like this ...
Pk EmployeeiD Date Time
1 Emp1001 5/8/2012 00:03:02
2 Emp1001 5/9/201200:03:02
3 Emp1001 5/10/201200:00:49
the above values are inserted successfully.....in their respective dates....
If i insert the above values again in the same table means
(ie..)Employeeid Date Time
Emp1001 5/9/2012 00:03:02
it will show some message like (Date Already Exists)....
I didnt use Constraints in my table... I didnt know about constraints...am a Beginner
